  1. too dark
    147
  2. Check out Ed Nash's Military Matters channel also Had planned this video a week or so ago but the Ursa Major ship attack trumped it
    124
  3. Yep. I am calling these jack ups for ease of comms, and because I think that they are, but not 100% confident. The sketch maybe needs a subtle adjustment to the waterline but too late now. Was thinking about that as I spoke but didn’t expect anyone to notice! Love this quality comment, thank you
    119
  4. haha, low views because I only uploaded a few minutes ago I hope
    110
  5. I'll give it some thought, thanks
    104
  6. It’s not :)
    101
  7. Appreciate you covering this forgotten conflict
    94
  8. https://www.youtube.com/watch?v=PdKkR_lbLN0

  9. Update: now a satellite overpass allows us to glimpse how effective it is against OSINT (Open Source Intelligence) using free satellite images. See -> http://www.hisutton.com/Russian-Navy-Deceptive-Camouflage.html It is reasonably effective, definitely will make it a lot harder.
    81
  10. Yes, that too. For example, shooting them around an island in the Swedish archipelago. I think that I wrote an article on it for Forbes a few years ago.
    67
  11. haha. understood
    60
  12. Noted!
    50
  13. Oh, wasn't aware, must check it out.
    50
  14. Couldn't resist, hopefully you get the reference? Australian skit https://www.youtube.com/watch?v=3m5qxZm_JqM
    45
  15. thank you!
    45
  16. Or the less good sense, depending on your perspective
    42
  17. Yes, you are describing a few variations which exit. Some of the fully submersible vessels (FSVs) are towed most of their way. And if uncrewed, it is termed a towed-narco torpedo.
    42
  18. I thought about it, but landed on Fateh Class
    40
  19. Thank you!
    39
  20. Authenticity! real youtubers will be copying my style before you know it
    37
  21. boom boom
    37
  22. Thanks, I'm glad you enjoyed it!
    36
  23. Yes, although I think the opposite is also true: these barges make steeper and rockier shores accessible too. There are quite flexible. Not disagreeing with your observations, but I was thinking that the type-1/3 are still quite shallow draft too, not sure how differentiating it is between the types. Still digesting these, they are new afterall
    36
  24. Wow, thanks
    35
  25. Exactly
    34
  26. Glad you like them!
    33
  27. This tracker only deals with anti-ship capabilities of both systems. Range rings for Kalibr used are 3M54K
    32
  28. Wow, thanks! I think I know the channel you mean. Not sure I am in that league, but I will take the compliment!
    32
  29. Thanks. Yes, possibly
    31
  30. Two very quick answers. Yes in many cases I think that they do transship mid ocean, as crazy as that might seem Only one design can really be tied to Russian engineers and that was 20 years ago. And others are nothing like that one. So in general, no real influence
    31
  31. interesting, wasn't aware
    31
  32. Thank you, glad it is all worth while
    30
  33. I never learn
    29
  34. submerged is more discrete
    28
  35. how far through the video did you watch?
    28
  36. Thank you. I will see about how to edit these points.
    26
  37. Yes saw this question, Maybe in future I will get to an article on torpedo tube arrangements etc, fascinating variations abound
    24
  38. Interesting thought. Saboteurs could screw a double hull sub pretty much as easily as long as they knew what they are doing I'd suggest. Subs are very vulnerable if targeted in port
    23
  39. I made some tweaks (typos in dates, added USS Argonaut). YouTube doesn't allow much in the way of improvements so had to re-upload
    23
  40. Oh, missed the anniversary. Pity, nice little interest point. Thanks
    22
  41. Never heard of Bondi Rescue. The script writers obviously hadn't watched the narco subs video
    22
  42. Thank you!
    22
  43. yes, great points.
    22
  44. Yes, I meant of BSF. This is unscripted, so sometimes miss details
    21
  45. In the context of USVs, the new capabilities this USV brings changes the equation. P.S. It's clear you cannot of watched the video before posting this, it hadn't been published long enough
    21
  46. Thank you! Cheers!
    21
  47. Touche! damn, I missed the opportunity for that joke!
    20
  48. haha, i will try to remember that
    20
  49. Thank you very much!
    20
  50. I made some tweaks (typos in dates, added USS Argonaut). YouTube doesn't allow much in the way of improvements so had to re-upload
    20
  51. Noted!
    20
  52. if i did longer ones i could send you to sleep :)
    19
  53. Thank you!
    19
  54. Nothing positive to say about that article, its a conspiracy theory.
    18
  55. Much appreciated!
    18
  56. Thank you!
    18
  57. Wow, thanks
    18
  58. Many thanks!
    17
  59. I would think (and I believe other analysts agree), that yes they are scuttled too. Re profitability, one trip is more than enough
    17
  60. Thank you!
    17
  61. Sounds fantastic to watch. Stay safe!
    17
  62. Much appreciated!
    17
  63. Check Spanish news and specialist shipping/naval sources. It will be, I am a defence analyst I tend to be ahead of much news media on these things
    16
  64. Or it shows the maintenance issues with the older ships?
    16
  65. Other German cruiser subs had a depth of 75 m (246 ft). This would have been the same, or probably less due to the complex structures amidships.
    16
  66. Thanks a ton
    15
  67. Coming soon! But for now, it has to wait.
    15
  68. What's my message?
    15
  69. ?
    15
  70. Stop water running up the exhaust into the engine, like the reverse of the ubend in your toilet
    15
  71. I wouldn't want to speculate, not something I know enough about
    15
  72. that's a question in my mind also
    14
  73. I try
    14
  74. I would have gone A, B, C based on size, then D,E... etc based on chronology after that. But using Tom's is better than adding my own ideas to the mix
    14
  75. I don't have 100k subs ;)
    14
  76. Thanks for the sub-sub!
    14
  77. Sorry about that
    14
  78. To clarify, the later ones were oil.
    13
  79. Hi Mark, interesting video. 2 things, staff officer demands of NATO/alliances and the possible advantages having senior officers gives us in that space(?), and scaling up. We can build ships quicker than we can train/develop senior staff officers (admittedly the snails pace we build Astute class submarines would be a bad example). The short of it is however, sadly, we badly need more ships, submarines and a massive fleet of uncrewed platforms.
    13
  80. Appreciate that
    12
  81. I geolocated it using Google Earth, no trick tools. The lack of background landmarks was a pain but familiarity with Chinese shipbuilding helped. Geolocation on this one is maybe 80% confident
    12
  82. haha
    12
  83. Spanish term is 'ghost gliders' (planeadora fantasma) if I recall correctly. Cool label
    12
  84. Yes, although in what way is a mulberry harbour not a pier? ;) We haven’t come up with a catchy name yet, invasion barges don’t sound a big deal but these are
    12
  85. Agreed. Meant to say that
    12
  86. "Operation of a submersible vessel or semi-submersible vessel without nationality", laws in US and I think Colombia which are used. Response specifically to narco subs
    12
  87. Glad it was helpful!
    12
  88. ?
    12
  89. This. China is actually the only country which can hide new submarines 'in plain sight' as well as this. DPRK etc maybe but different scenario. Re the Yuan Class, which I think that you are referencing, that's one which we don't know the real designations of, except the Type-039A. We have a -B, -C and maybe a -D variant but which counts as which is really speculation. China is in no hurry to help Western observers learn about their subs.
    12
  90. Narco subs, running in displacement mode with the deck awash, also do about 12 knots although some are a bit faster
    12
  91. thank you
    11
  92. thanks, yes!
    11
  93. Many thanks. Possibly might do a video on it some time
    11
  94. Possibly, but wouldn’t expect it to have a towed sonar and possibly not torpedo tubes
    11
  95. MS Paint Some shading in GiMP, some bits in PowerPoint
    11
  96. Interesting thought although I don't think so. Other Poseidon-carrying submarines do not have this capability.
    11
  97. Yes, although we'd still call them single-hulled. In practice all single-hull designs have some area of double hull for ballast, trim and equipment, even if only at the bow and stern.
    11
  98. 1. No 2. Maybe. There are a whole bunch of designs which are more interesting than the average, and this is one of those.
    11
  99. Yes, that is a technique especially in Dark Ships which turn off AIS. Radar satellites too. But they are not omnipresent, and often have issues with cloud etc. Plus most optical satellites don't image open ocean. So it is hardly a magic bullet
    11
  100. yes it's international shipping lane, Britain and France play by the rules. The ship was escorted by Royal Navy, then later Spanish Navy and Portuguese Navy
    11
  101. Glad it was helpful!
    11
  102. Thanks
    10
  103. Hi, yeah it's a Q&A video responding to questions from my twitter followers. No trick, it's not commercial or anything, I'm just a guy who started making Youtube videos after I discovered I could record them. Top-5 SSKs was the bravest question. No idea how chapters work on youtube. Hopefully if you are interested in submarines then the other questions are equally interesting.
    10
  104. Yes flight deck
    10
  105. Bound to be some fuel etc, but this wasn't a tanker
    10
  106. They exist, more popularly called ship spotters. Some knowing, some unwitting. But they have limited sight, endurance and are geographically contained. In wartime they may be deemed as spies etc.
    10
  107. It was a reference to Hunt for Red October
    10
  108. Found it in Studio, thank you!
    10
  109. Sounds fun, thanks
    10
  110. Evidently not very in the traditional sense, the ship returned to base under own power with no visible signs of damage. The attack was arguably successful as part of the wider shaping of Russian naval activity
    10
  111. The VLS in the A-26 is only an offering, no customers currently and no boats built. The first KSS-III was laid down in 2016 (and would have been designed years before). The A-26 models with VLS were first shared in 2017(?)
    10
  112. Much appreciated!
    10
  113. I nearly included Gepard or IRIS-T, or Patriot, or S-400.... but I realised I was trying too hard to find an iconic weapon in that category. I watch the AD space relatively closely, but I don't think these weapons are shaping the public narrative. Maybe the 'DragonFire' laser AD will, but difficult to predict the future.
    10
  114. Thanks
    10
  115. Yes massive typo running all the way through "GTP" not "GPT" ... rerecorded and reuploaded
    9
  116. Yes, thanks. Cannot edit this
    9
  117. Wow, thank you
    9
  118. Hope you enjoy!
    9
  119. I think a bigger reason is simply because history is largely written by the winners. And also that a lot of their later designs were 'last ditch' devices which, deservedly, are regarded as of limited effectiveness. Plus their better last ditch designs didn't see combat. Not saying that they were overall better, and they certainly had some limitations, but researching them has been full of surprises. In some respects they were ahead
    9
  120. Welcome aboard!
    9
  121. yes I think that also, if you have access to multiple elements, you could investigate erroneous coordinates etc. Maybe even screen them out, although you would want to be sure. But as end-users we can only speculate
    9
  122. AIP propulsion never materialized, lead boat of class will reportedly be retired early due to extent of its issues. Plus points, large sonar, powerful weapons and typical (high) Russian standards of stealth
    9
  123. I do not believe that the Dolphin-IIs larger tubes are for a larger torpedo. Instead cruise missiles. Here is a cutaway I drew, although also with a provisional take on the VLS https://www.navalnews.com/naval-news/2022/01/israels-submarine-secret-new-dolphin-class-boat-could-have-vls/
    9
  124. I appreciate that!
    9
  125. Is that a good thing?
    9
  126. not unusual weather there i think
    9
  127. Cheers!
    9
  128. There are two Russian subs called Akula The Pr.941 is called Akula (meaning shark) by the Russians. NATO reporting name is TYPHOON. To see why,, see http://www.hisutton.com/The%20REAL%20Red%20October%20-%20Typhoon%20SSBN.html The Pr. 971 is called Shchuka-B (meaning pike) by the Russians. NATO gave it the AKULA designation. This is the one you have heard about. I tend to use the military/navy norm of using capital letters for NATO code names and lower case for regular names. But it is hard to do always, especially when trying to write for a wider audience
    9
  129. Glad you like them!
    8
  130. Glad you enjoyed it!
    8
  131. They use degaussing
    8
  132. Glad you enjoyed it!
    8
  133. Thank you!
    8
  134. I've been informed that naval architects don't use MS Paint
    8
  135. It was unrealistic and would not be the choice thing to acquire
    8
  136. Hi, not a video, but might help https://www.navalnews.com/naval-news/2021/09/the-5-main-options-for-australias-aukus-nuclear-submarine-deal/
    8
  137. Thanks for the kind words The war in Ukraine has messed up the usual flow of topics, hope to be able to get back to focusing on submarines soon
    8
  138. Glad you like them!
    8
  139. I'm not monetized on Youtube
    8
  140. Agosta class was hard to categorize.
    8
  141. Thanks! Yes, Das Boot of course. No other answer would be acceptable. In German with subtitles too, ideally the TV series
    8
  142. It's mentioned https://youtu.be/iWmf3SvPFE0?si=7-s_wKuLVLYNc_2l&t=612
    8
  143. thanks!
    8
  144. Some sense because of the reserve buoyancy, but overall it's not the biggest factor for arctic ops. Submarines have to be hardened to break through the ice and USN and RN use single-hull subs.
    8
  145. Glad it was helpful!
    8
  146. decent call. Thinking more infamous than iconic?
    8
  147. Prepare for death! https://youtu.be/PdKkR_lbLN0
    7
  148. Good point. Maybe, pitting fore sure. Was thinking that the fact that they are at the leading edge of the first row of blades made me think it's more like impact, which is also a thing obviously. Many nuclear boats cannot bottom out so I guess that they get less damage
    7
  149. Glad you enjoyed it!
    7
  150. Glad you enjoyed it
    7
  151. thanks
    7
  152. Thanks for watching
    7
  153.  @BeKindToBirds thanks, this, plus it’s not monetised and not trying to maximise audience at the cost of content. Others have said it better than me, thanks all
    7
  154. Interesting!
    7
  155. thanks
    7
  156. Short answer is, early subs spent more time on surface than submerged. So needed to be more boat-like.
    7
  157. So nice of you
    7
  158. I think you might mean Lotus?
    7
  159. For what it is worth, criticisms are normally a) moving turret might have leaked, possibly causing its loss b) aircraft usefulness for spotting, c) concept of surface raiding submarine d) $$$$$$ My piece on her http://www.hisutton.com/Surcouf.html
    7
  160. I think it's more a factor of which criminal groups are involved
    7
  161. Thank you very much!
    7
  162. Whales and stuff goes much deeper. Nature is wonderous
    7
  163. Much appreciated! I do defense analysis so I build up the knowledge and sources over time, I have been watching Snake Island since Feb 24/25. This is why I am trying to share the info
    7
  164.  @ivancho5854 one ping only
    6
  165. Hope you enjoyed it!
    6
  166. Hey, thanks!
    6
  167. The 2015 deal? It wasn't a Naval base and stopped after the 2022 full-scale invasion of Ukraine
    6
  168. basically lead acid I think, with lithium based tech being the new thing
    6
  169. Interesting thought, but doesn't seem borne out by the way they are trialling them. So, don't think so.
    6
  170. Thanks
    6
  171. Sorry, I focus on other country's subs and gear
    6
  172. Shang Class
    6
  173. Thanks, will do!
    6
  174. Agreed, and in Libya.. but I think the Russo-Ukraine war gave it infinitely more world awareness
    6
  175. i think it's legit. The camera has multiple modes depending on circumstances, including IR
    6
  176. 1 x River Class, but not operational
    6
  177. 1950s A conning tower, at least typically, had a compartment in it for steering the submarine while submerged. In 1950s they stopped that and renamed them sails / fins / kiosks Sail is American and general Fin is Royal Navy lingo Kiosk is French term used generally for sail or conning tower (I think!)
    6
  178. Thanks I think I know the types of books you mean, they still inspire me
    6
  179. To clarify, the video doesn't say that it was developed from the KIROV class
    6
  180. Yes, agreed, but I do not feel qualified to do a video on these more political aspects
    6
  181. Most, otherwise they'd have stopped years ago I estimate about 1,000 have been built I have logged ~200 as being stopped
    6
  182. I need to do a video on submarine guns, mainly the awesome, crazy and obscure stuff. Added to the very long list
    6
  183. Glad it helped!
    6
  184. Japan is far from alone. X-rudders were first tested by US Navy in 1950s, then first adopted by the Swedes, then Yugoslavia, then Netherland. Japan, Germany, France all use them, UK and USA will soon, and China does on AUVs.
    6
  185. thank you
    6
  186. Analysis of movements/firings etc
    6
  187. No, they are blocked from entering the Black Sea by Türkiye, under a different part of Montreux
    6
  188. why?
    6
  189. Much more the former. I discuss the reason at the end of the video, it also has to do with economy
    6
  190. These would be my picks too.
    6
  191. No, none reported, not really suspected either
    6
  192. Yeah I wasn't happy with it. Once you upload Youtube gives you very limited options to edit it so ended up re-recording. Learning experience, still new to Youtube
    6
  193. Glad you enjoy it!
    6
  194. I appreciate that! Thanks
    6
  195. Yeah that bit wasn't clear, sorry. The chemical reaction I was referring to was in the metal hydride accumulators, and when I said "offloaded", "Used by the fuel cell" would have been a much better choice of words. At that moment in the recording I think I was wondering whether to go into reformers or not. Will try to edit the video but options are very limited once it is uploaded.
    6
  196. I'll try to remember next time I do a Q&A.
    6
  197. One problem with COTS products is that they often aren't stealthy enough. One of the reasons submarines are so expensive these days, every detail is important and so much has to be specially made.
    6
  198. Wow, thanks! Had no idea. Hopefully not Elbonia?
    6
  199. Thx Russia and of course UK also have anechoic tiles/coatings. the Russian one is quite sophisticated I hear
    6
  200. Good to hear! I don't always have a decent mic to hand, and this one is patchy. Definitely not a pro, just sharing
    6
  201. Thanks for listening
    6
  202. I'm probably just out of my depth
    6
  203. Appreciate it, glad you like the content
    5
  204. The barge becomes a pier essentially. It doesn’t transport the tanks, ROROs do. The tanks drove across the barge like a bridge
    5
  205. Awesome! Thank you!
    5
  206. Thank you. Good to know and wouldn't surprise me. Seawolf's might be different.
    5
  207. Definitely don't take pronunciation hints from Sutton
    5
  208. Glad you like them!
    5
  209. Possibly, it's the road ahead. Although that too requires development and integration. There have been reports of RuN trying Li tech batteries but not in this application yet
    5
  210. drawn in MS Paint, shaded in GIMP
    5
  211. There is a nuanced and complex agreement called Montreux Convention (https://en.wikipedia.org/wiki/Montreux_Convention_Regarding_the_Regime_of_the_Straits). Currently Russia is seen as pushing the limits regarding restrictions on submarine movements, and each party might want to remove limits placed on them. But really none of the parties want to throw it away either. In a way, it's doing its intended job. HOWEVER, right now, it gives Russia a Naval advantage in the Black Sea
    5
  212. You use a lot of good words in your reply
    5
  213. Yes high bandwidth 2-way comms for sure, likely satellite
    5
  214. 20,000 liiters
    5
  215. The diver doesn't stand much chance, won't see the dolphin coming. And any attack is anyway likely at night
    5
  216. British tactic used in Malaysia/Singapore etc during period of Indonesian confrontation
    5
  217. Awesome! Thank you!
    5
  218. it's not on my list I am afraid (I have to be honest here, my list is far too long), but Collins Class is
    5
  219. My pleasure!
    5
  220. With the benefit of more info, it appears that the USV attacks were not a diversion, but rather a separate action aimed at the tanker Yaz and arms transport Ursa Major which transited the Black Sea towards Bosporus. Possibly as many as 12 USVs were used in 4 groups. Details still emerging, usual caveats. Update on my Naval News article https://www.youtube.com/watch?v=OFfURH-qhEY Minor detail., at 6:13 it suggests the boat KS-701 was hit during this action, that's mistaken. KS-701 was hit Sep 3.
    5
  221. Thanks for the feedback!
    5
  222. ?
    5
  223. Makes sense, yes maybe
    5
  224. no
    5
  225. Drachinifel has a really cool channel, looking forward to his piece on torpedoes. Would be nice to collaborate some time but not sure if its practical, and doubt that he needs me
    5
  226. This does happen, however, a) it takes a lot to sink them, they tend to be fiberglass which floats. Setting fire to it is a common way. b) the crew are then relying on a rescue strategy, which is a health risk most are wary of. c) they go to jail anyway even without the cocaine being recovered. It is a crime to be in an unflagged semi-submersible. This law is relatively recent and makes it safer because it disincentives abandoning ship, which is dangerous for the crew d) LE can in some cases recover the sunken vessel anyway
    5
  227. Thank you kindly!
    5
  228. You're welcome
    5
  229. I am already aware of other names being used, it will evolve I am sure
    5
  230. I wouldn't
    5
  231. cardboard derivatives?
    5
  232. Thanks!

  233. The USET-80 isn't particularly influential on NATO naval planning. I am not sure what you mean that NATO instigated a proxy war, and if they did (they didn't), it wouldn't because of a torpedo
    5
  234. I appreciate that!

  235. Sorry, are you referring to the Brahmos missile which is illustrated? There are three missiles in my illustration, talk: Hyunmoo-4-4 - SLBM, I would think the main weapon going forward Hyunmoo-3C - SLCM, like Tomahawk. Low-supersonic - I do have an error/oversight in not mentioning the jet phase but cannot edit the video Brahmos - mentioned in context of P75I competition Re AIP, to clarify, I think that it is a game-changer to combine modern AIP with a VLS, and more so because of the small SLBMs. AIP has both pros and cons over nuclear. This video discusses pros and cons of AIP. https://www.youtube.com/watch?v=c2QS_aEsVuw This video was made before the AUKUS announcement. I haven't changed my view on the significance of the KSS-III Hope that this helps.
    5
  236. I wrote a piece on my blog about it http://www.hisutton.com/Sailless_Submarines.html maybe should do a video some time
    5
  237. I think that they did more or less, at least in the way you'd expect. There aren't any meaningful targets for them though so it didn't have much impact except blockade.
    5
  238. It was Rostov on Don
    5
  239. Hey, I use PPT too! :D
    5
  240. Yeah terrible timing!
    5
  241. Thank you
    4
  242. Yeah but I had to mention Sutton obviously
    4
  243. Yes, but the larger ones are understood to be for missiles. See my cutaway at https://www.navalnews.com/naval-news/2022/01/israels-submarine-secret-new-dolphin-class-boat-could-have-vls/
    4
  244. Yeah I try to say "lithium-based" instead of "Lithium-ion" but it's hard not to slip up. There are a few different variations being developed in different places, and submarine applications are likely to capitalize on the safest variations.
    4
  245. vaven't been able to confirm, but very likely compressed air based on the Whitehead torpedoes available at the time
    4
  246. "I wonder how much of the technology is Dutch.. Waard VIS - Sword Fish with a vvvvv same differences between f and v as there is between s and z...stop saying w when it clearly sais , vvv, and do your HOME WORK before you do a video, don't be so disespectful! Don't you yanks have schools???" Pardon?
    4
  247. Much appreciated
    4
  248. interesting suggestion
    4
  249. thank you
    4
  250. Yes, pretty much
    4
  251. In case you don't find it... https://www.youtube.com/watch?v=PdKkR_lbLN0

  253. I tend to use a loose orthographic projection to keep vertical straight up (not angled towards the viewer) so the deck spacings get distorted. I draw them by eye.
    4
  254. Happy holidays!
    4
  255. Thanks. Side note. USS Jimmy Carter has a pumpjet
    4
  256. By Türkiye And concrete
    4
  257. Just the paint, pretty normal across many countries. USN too on many classes
    4
  258. One has new crew, the other no men
    4
  259. This
    4
  260. Wow, thank you!
    4
  261. Yes the attack took place
    4
  262. The challenge is that it appears to be "many more beaches/coastal areas than before with traditional landing ships" - they basically open up vast swathes of previously 'safe' coast
    4
  263. No, not deliberate. I think that the Russian systems will be less iconic.
    4
  264. Thank you, I will
    4
  265. Yes, so your professor was CDR Bill Green? Both stories are true, I chose the scrapyard one as it had the serial number. See this excellent book (well worth buying!) See https://books.google.ch/books?id=p8WkkBIeKR4C&pg=PT351&lpg=PT351&dq=scrap+titanium+pennsylvania+alfa+submarine
    4
  266. thank you!
    4
  267. I might have, somewhat ;)
    4
  268. Agreed. The sailless sub is all the proof we need that China can be innovative and is looking to be leading edge
    4
  269. Hi, towards the end of this video I touch on that https://www.youtube.com/watch?v=c2QS_aEsVuw
    4
  270. Yeah classic
    4
  271. Crewed boat
    4
  272. thanks
    4
  273. an inflatable dingy maybe, life jackets probably.
    4
  274. Possibly this one? http://www.hisutton.com/Swiss-Pedal-Powered-Smuggling-Submarine.html
    4
  275. Seaeye Marine was a British company acquired by Saab in 2007
    4
  276. Yantar carries deep-diving submersibles, ROVs and likely UUVs. More survey than EW. Interesting ship http://www.hisutton.com/Yantar.html
    4
  277. thanks!
    4
  278. Yeah, if anything it's higher. I deliberately make my models conservative. However, we also need to consider that the number has fluctuated over time, with much less activity in some years etc. And the relative amount of payload per trip is also a factor. My 200 includes a few which completed their trips actually.
    4
  279. Interesting line of thought.
    4
  280. Yes, for torpedo reloads in the torpedo room. The A-10 Hajen-III Class too. And the A-13 Class had a rotary external launcher for 400mm torpedoes in the rear ballast tanks, like these A-11 designs. That's where they learnt it was a bad idea I think. Some general info http://www.hisutton.com/Swedish_SSN.html
    4
  281. The outer hull of a double-hull boat can be streamlined into the optimum hydrodynamic shape, but at the same time it's increasing the wetted area of the boat because the surface area is larger.
    4
  282. Thank you!
    4
  283. Hi, yes surely it does, but don't have any stats to quantify it
    4
  284. yes, among other places
    4
  285. Just to point out, the AI got that wrong, it said AKULA
    4
  286.  @skutchBlobaum  It is defence analysis
    4
  287. If the comparison is between two submarines with the same pressure hull diameter (not overall width), then the double-hull has more space inside the pressure hull (because frames on outside) plus more space in the outer hull, so overall more places to put layers of quietening
    4
  288. Yeah I wondered about Turtle tanks, but more infamous than iconic? Iconic has a positive connotation, even viewed from the 'enemy' side
    4
  289. FYI they are dragging Assad statues through the streets of Latakia this morning, and the toppled statue in Tartus was included in this video
    4
  290. I consciously use uncrewed, and it is also normal in British defence, and among many other operators, organisations etc
    4
  291. Oh she's a beautiful ship too. We need the Hellenic Navy's Trireme OLYMPIAS too
    4
  292. well put
    4
  293. https://youtu.be/OFfURH-qhEY?si=3CWypQD8aLEVDCeL&t=278
    4
  294. I wrapped them up within "FPVs" even though many such drones aren't actually FPV,.. that's the label I think will stick
    4
  295. Interesting, I see what you mean. I don't think that the guns can retract at all though. And not confident re the hoist. Especially at the stern set. But intriguing trying to decipher the plans. I am sure we both have plenty of experience looking at plans like this and submarines in general, but we are likely both equally guessing! That is part of what makes it so interesting.
    4
  296. It's a beluga pen
    4
  297. My pleasure!
    4
  298. This one is being taken back to port.
    4
  299. I prepare some slides to walk trough, but do not script what I am going to say. Just a guy talking about submarines
    4
  300. I had meant to mention that they are normally bronze, but forgot. Another hint that the screw is titanium is the absence of sacrificial anodes.
    4
  301. AUKUS (or CAUKUS?) or Barracuda SSN would be best choice, but doubt they will go that way. Barracuda DE, KSS-III, Sorju/Taigei, A-26, Type-212CD and S-80P are obvious candidates in design/political terms
    4
  302. generally agree. Narco torpedoes are also used, and you could argue the relative pros and cons. But the cartels see narco subs as filling part of their transport needs
    4
  303. Agree re buoyancy differences between warshots and training rounds for torpedoes. Erring on the side of caution, I didn't want to give people the idea that any torpedo which washes up is unarmed though. There have been examples of warshots on beaches, although I don't know the full circumstances. Re size. Some lightweight torpedoes have washed up, and there are some very large drones. Including 533mm ones for torpedo
    4
  304. The 100MT thing was speculation. 2 megatons seems much more likely.
    4
  305. they appear to be symmetrical airfoils which can be attached to the fuselage from either end. The outer wings the same, except they have a top/bottom obviously.
    4
  306. Same to you!
    4
  307. just storm, but i understand more like divine storm, religious reference
    4
  308. no, different ships
    4
  309. That's a whole topic in itself. A few factors though... At a time it was thought that the increased lethality of individual torpedoes meant fewer would need to be shot at once. This logic led the USN to drop to just 4 tubes, something they are now stuck with in current generation designs. In the Cold War German designs generally went for more tubes but few or no reloads (and those reloads less accessible). This allowed the boats to be smaller and the 'torpedo room' to primarily be accommodation. Thinking Type 206/9/14 etc Separately, there was a view developing during the Cold War that nuclear subs were SOOO combat effective that they would run out of torpedoes before being taken out. So they started carrying 35-40 torpedoes. Thinking SIERRA, AKULA, Astute, Seawolf, Yasen. In some cases, notably Seawolf and Yasen, this meant two torpedo rooms, so more tubes. Personally I think that more is better, especially as navies will want to put more types of weapon and UUV through them. If you only have 4 tubes, and two are for emergency self defense,... it's a pain to pick what to load into the remaining two.
    4
  310. thanks!
    4
  311. Glad you think so!
    4
  312. thank you!
    4
  313. unlikely
    4
  314. I guess would be no. If anything they'll use as many of the slots for SLBMs as possible so maybe no cruise missiles at all.
    4
  315. Yes, although these boat's anti-submarine potential is limited.
    4
  316. Yes I forgot to include the Narval, cannot edit it in now unfortunately. Agree re its significance.
    4
  317. There have been a couple which are true submarines in the conventional sense. And a few more which are close
    4
  318. They had 4 Improved-KILO plus one original KILO, the one-off Alrosa. Now 3 + 1
    4
  319. I just make the occasional video when the opportunity is there.
    4
  320. Glad you enjoyed it
    4
  321. ASW isn't really realistic for these
    4
  322. Have they been holding back on Ukraine?
    4
  323. unlikely, that would add massive complications to the operation and technical design
    4
  324. You cannot possibly have watched the video before commenting, it was barely uploaded a minute
    4
  325. FYI it’s not monetised
    3
  326. Thanks for coming
    3
  327. Recharging underwater is a topic, mainly for UUVs. Is less likely with submarines any time soon though Coastal subs will, generally, have less sophisticated/powerful sonar, etc.
    3
  328. You can swim out of a regular tube too. Many variables of course.
    3
  329. Try https://youtu.be/PdKkR_lbLN0
    3
  330. No, there are tanks at the sides which would get in the way. Also, the torpedo reloads would be facing aft in the plans if that was the case.
    3
  331. haha
    3
  332. Happy to help!
    3
  333. most are fiberglass with marine plywood elements
    3
  334. Photo at @9.05 appears to show a forward firing gun mounted on the wing?
    3
  335. Yeah a few people have wondered about how many subs etc. Working it out would be more time than I can spare, but one thing to consider is that most submarines in the world spend much more time in port than at sea. And at-sea time varies greatly based on multiple factors.
    3
  336. no
    3
  337. No. Have done some articles and videos on these USVs over the months, topic I follow. The observations in the conclusion of this video are new
    3
  338. thanks, cannot change it unfortunately
    3
  339. Hi, was alluding to them in the masses of data comment. Russia and China have decent ones. However submarines are quieter so overall these are less of an advantage than they were at times in the Cold War.
    3
  340. Glad you enjoyed it
    3
  341. Hi, it is mentioned at the end, under AIP
    3
  342. I am probably not the best person to cover that, I see it from an analyst's perspective not an engineers. But basically lead-acid has won so far because of low cost (relative!!!), reliability, robustness to being recharged, and service life. Lithium-based techs promise to revolutionize things because their higher energy density translates into real operational differences. But safety is the main thing slowing their adoption down. We are on the cusp.
    3
  343. Cool, thanks!
    3
  344. It does not appear that this specific ship was conducting shelling, and certainly not Mariupol.
    3
  345. Only seen the plans and general descriptions. But I expect it is part of the reason that steam submarines in general took minutes to prepare to dive.
    3
  346. Thanks a lot 😊
    3
  347. Check out Wave Gliders and similar USVs. The main limitation is power, there just isn't much to be had compared to what UUVs consume to do any work
    3
  348. Check out this time-lapse https://youtu.be/PdKkR_lbLN0

  349. Sorry. 65-76A specs: Caliber - 650 mm Length - 11.3 m Weight - 4750 kg est Warhead - 557 kg est Rrange - 50 km @ 50 knots, 100 km @ 30-35 knots Maximum speed - 50 knots Travel depth - 14 m Launch depth: - up to 150 m (according to the results of state tests, 1975) - up to 480 m Submarine speed at launch - up to 13 knots
    3
  350. my layperson understanding of Quantum is that it needs a lot of power It is already used aboard some larger submarines
    3
  351. Oh? Great! Thank you
    3
  352. I don't think he was arranging them like I did, he was just labelling sat imagery to differentiate the observed types
    3
  353. Iran has one, China has built two already
    3
  354. Almost
    3
  355. Yes, as I think I might have said, it's dated. If I didn't, I should have! I feel that the significance is how it is intended, and also as the cruiser at the center of a group. Overall thoughts on Ru anti-ship capabilities, although with caveat that focusing on 'carrier killing' capability. http://www.hisutton.com/Russian-Anti-Aircraft-Carrier-Weapons.html
    3
  356. Not sure I know which trunk you mean, but they do carry MANPADS 100%
    3
  357. Per the title, World War One not Two. Ultimate in design terms.
    3
  358. i nearly put it in
    3
  359. I don't think it's an approach which is being considered. Wouldn't flooding part of your sub just further add to the problems? There is a thing with nuclear submarines where they flood the bottom of the reactor compartment in some emergency scenarios, to act as a heat sink.
    3
  360. Video on Steam Powered submarines https://www.youtube.com/watch?v=pg_j8_NjZxw And one particularly interesting design https://www.youtube.com/watch?v=67IritgM79U

  362. See Su-30SM https://en.wikipedia.org/wiki/Sukhoi_Su-30#/media/File:Sukhoi_Su-30SM_in_flight_2014.jpg
    3
  363. Wow, thank you!
    3
  364. I have an answer... https://youtu.be/qWeg7OCGw4Y?t=989
    3
  365. With hindsight, yes. But asking to stop and then attacking is a new tactic. If you are on a civilian ship and the Houthis (or IRGC) instruct you to stop, you have a difficult choice.
    3
  366. 12-14 knots generally. Some might be faster in optimal conditions. generally 2,000 nautical miles but some 5,000 nm (estimate). One has demonstrated 3,920 nm
    3
  367. The uncrewed one at the defence show had a diesel generator too, although a small one
    3
  368. Agreed. The torpedo used by Venturer wasn't an "anti-submarine torpedo". Since the 1950s various projects focused on exactly that.
    3
  369. sounds unhealthy
    3
  370. Eventually. Check out http://www.hisutton.com/North-Korea-Submarines-Compared.html and http://www.hisutton.com/North-Korea-Submarine-Hero-Kim-Gun-ok.html
    3
  371. It's a great question, I think it shows how becoming iconic isn't so much about numbers. It's different from 'common' or ubiquitous, although some common and ubiquitous things can become iconic, for example the Jeep
    3
  372. You're welcome!
    3
  373. Good to know! Pure fluke

    3
  379. Think he's fine
    3
  380. Not at all, but this is something I have been mulling a long while, finally got around to it. I often find myself writing a short overview of the war so far, and that got me thinking.
    3

    3
  384. Yes I think so, but these videos I am told originated with Hush Kit (not Forgotten Weapons as I believed)
    3
  385.  @mydreamsaloft7040  I drew it
    3
  386. Flat bulkheads are found on a number of designs, doesn't necessarily mean not deep diving, at least by the standards of the day. DELTA class SSBNs are a great example, but there are more
    3
  387. Welcome aboard!
    3
  388. Yeah that video is great. The Gato Class was double hulled. Throughout WW2 era there were many of both types.
    3
  389. They say long range acoustic communication. Limited but not entirely implausible in my view
    3
  390. Glad you enjoyed it
    3
  391. Thank you too!
    3
  392. I appreciate that!
    3
  393. Yes. Some FSVs do appear to have ballast tanks, but not the one in the first cutaway. Some used lead weights too.
    3
  394. It's been proposed a few times. In general, when torpedoes are carried 'externally' they are still under the streamlined casing of the submarine. External means outside the pressure hull. There have been some concepts for carrying them external to even the casing, like on a plane. But no one has really gone for it except a few midget subs. There are pros and cons to external carriage, They cannot be maintained while underway and are not necessarily easier to reload.
    3
  395. I am not a pro, just use whatever I have to hand. No editing, no scripting... sorry but all I have time for
    3
  396. Hi, not aware of any evidence Russia placed area air-defense systems on the Island. I think that I mentioned that they only placed local air defenses
    3
  397. Glad you like them!
    3
  398. 2 missing last i heard. 14 off safe
    3
  399. Yeah. No periscope either. It had a conning tower of sorts.
    3
  400. Very challenging, communication would make coordination very difficult

  405. You're welcome
    3
  406. Yes maybe in the future. So many possible videos and articles though so no promises. But that specific topic is already on my mental list
    3
  407. Thanks, yes good info. Was aware re first of class having the screw, just not going into so much detail in a video. Re fragility, interesting. But have got the frailty from somewhere. You might like my article and cutaway of the T-boat. Not intended to be 100% accurate for very obvious reasons, but hopefully captures the feel. Also, mix of individual boats in internal arrangements. http://www.hisutton.com/Royal-Navy-Trafalgar-Class-Submarine.html

  413. Thank you!
    3
  414. On Youtube it's just this.
    3
  415. That's one way, as it describes for the Seawolf. But there are no plans for this now. In general better battery technologies will be what gives better ranges
    3
  416. yeah i thought about it, it is a contender, especially the later ones where you cannot excuse them for being the first nuclear sub Type-092, Type-033G, Type-035 and Type-039 too

  426. And still are, but I think they fall within the 'FPV' label even though many are not FPV (some are)
    3
  427. My audience are above average
    3
  428. Well put, I might steal that line for a future video As we know, Russia doesn't have the level of safety issues popularly claimed.
    3
  429. Because they gave up on having a Titanium screw it seems
    2
  430. Incredibly, yes. But its not a common inspiration See http://www.hisutton.com/Narco_Seehund.html
    2
  431. By the USN system. SSRN would be a radar picket submarine, which was a thing at the time. But Hollywood probably meant 'research' like you say. I didn't include SSRN because it is no longer relevant. But Seaview would be an SSAN in my view. Cool retro TV
    2
  432. Yes, I broke the story in USNI a few months back https://news.usni.org/2022/04/27/trained-russian-navy-dolphins-are-protecting-black-sea-naval-base-satellite-photos-show

  438. Easily, Bosporus is too shallow for a submerged transit, reputedly due to the concrete blocks intended to prevent exactly that
    2
  439. Somewhere between 16 and 89
    2
  440. I appreciate that!
    2
  441. Thank you, very cool contraptions

  443. The Syria Express used merchant ships to move military supplies and continued after Türkiye blocked the straights to warships of Russia and Ukraine. They stopped in early 2024 See https://www.navalnews.com/naval-news/2024/03/vital-russian-supply-lines-in-black-sea-cut-by-ukrainian-drones/
    2
  444. I think it's more a switch of focus
    2
  445. The 'rule' has varied over time and is different between navies. I used one at the deeper end
    2
  446. It's behind the smoke.
    2
  447. Very little. In JMSDF "classes" are as much about budgets as material differences in design
    2
  448. Yep. I broke the story for US Naval Institute back in April. https://news.usni.org/2022/04/27/trained-russian-navy-dolphins-are-protecting-black-sea-naval-base-satellite-photos-show
    2
  449. Brilliant stuff! Resonates
    2
  450. hi, those details are not public (at least wen I recorded this. Sorry)
    2
  451. For the moment it's where the machine gun was in WW1?
    2
  452. Thanks!
    2
  453. There are photos of the attacks throughout the video, and a sat image.
    2
  454. information
    2
  455. Those are cool, but wasn't able to find any which match. This is metal. Also, we could positively ID the jet drive as off a Sea Doo
    2
  456. Wow, thank you!
    2
  457. Yes you are correct, apologies,. Too rushed.
    2
  458. Yantar was in the general vicinity of Tartus in recent weeks, but like the rest of Russian ships, stayed outside the port. She called on Egypt and Algeria
    2
  459. Sometimes new info comes to light, for example see this sub http://www.hisutton.com/Russian-Navy-Belgorod-Submarines-Evolution.html
    2
  460. Yes, although more like a rail or liner system rather than discarding sabots
    2
  461. Not sure where they got that from but I would not give it any credence at all.
    2
  462. 1 would be useful. Depends greatly on what size/type and where they are laid.
    2
  463. Based on the TYPHOON class
    2
  464. I had meant to mention that they are normally bronze, but forgot. Another hint that the screw is titanium is the absence of sacrificial anodes.
    2
  465. fair
    2
  466. A bit like this? http://www.hisutton.com/Nautilus-2020_Luxury_Submarine.html
    2
  467. Glad you enjoyed it
    2
  468. They are likely very good
    2
  469. Glad you like them!
    2
  470. Glad you like them!
    2
  471. Not very long ranged, so Ru dolphins and I expect seals get carried in a small boat, like a RIB. Belugas would be harder but they do somehow
    2
  472. Yes, but I don't think anyone in USN thinks Seawolf is faster than PAPA Class
    2
  473. not inherently. You could argue that double hulls allow more space/layers of sound insulation but the specific quietening tech is a much bigger factor.
    2
  474. With the indirect method, yes. Peroxide AIP subs are mentioned at the end, along with nuclear. No one would call a Peroxide AIP sub a steam sub though, same for nuclear.
    2
  475. payloads vary, usually 35 million USD or more
    2
  476. https://www.youtube.com/watch?v=PdKkR_lbLN0 might help
    2
  477. good question. Most make it through, obviously. These are seen as safer than the go-fasts, but some must be lost at sea. I'd guesstimate less than 5% lost.
    2
  478. I was among those who thought it was pointless and doubted how serious the attempt was. Moot point now. Re repairs. I don’t have the research to answer that fully, but the recent French SSN which got hit by lightning is an extreme example. Fascinating in itself. Oh maybe I should mention this in the Q&A after all
    2
  479. I'll do a separate video on construction. It costs a few million USD. Very few have radar, exceptions rather than the rule
    2
  480. Short answers... Actually submarine pressure hulls are much thinner than you''d imagine. Tricky to put a figure on it, but thin. Yet they are incredibly strong. Titanium deforming is relative On a typical double-hull submarine like the Alfa and Sierra, the outer hull is thinner (known as lighter). It is normally made out of the same material as the inner hull to avoid differential metal corrosion. On these titanium subs it is titanium too. Non-magnetic is a factor, but not the main one.
    2
  481. Glad you enjoyed it!
    2
  482. Die feeling reassured
    2
  483. yep
    2
  484. Thank you for the kind words!
    2
  485. I thought about it, plus Type-035 and North Korean boats... but landed on Fateh
    2
  486. Mk 37s 19" weapons?
    2
  487. Try this Q&A video I made which covered pros and cons of sailless subs https://youtu.be/qWeg7OCGw4Y?t=989

    2
  489. The real pic has a Lenin poster, I put Ian over that
    2
  490. Bluesky
    2
  491. Yes I expect so
    2
  492. Actually Russia issued notices prohibiting merchant ships sailing the northern part of the Black Sea at the very start of the invasion. A Russian blockade was in full effect until the agreement in July
    2
  493. EO, from L3 Harris: https://www.navalnews.com/naval-news/2023/10/america-providing-advanced-systems-for-taiwan-new-submarine/

    2
  495. Torpedo loading hatch. The torpedo is shown
    2
  496. Glad you like them!
    2
  497. Yes length isn't standardized, but naturally the tubes built into subs puts natural parameters on this. In the 1950s some navies (e.g. USN, RN), built 'short' 533mm tubes into the stern of some classes. At the time they fitted specific models of torpedo. But subsequently these turned out to be almost useless as new weapons were no longer 'short'. (separately there were projects to reuse these tubes for other things like SDVs and towed arrays)
    2
  498. Glad someone spotted my childish sense of humour
    2
  499. Yes, but relatively few. We know it happens, there are graveyards at the bottom of the ocean were they finish their trips
    2
  500. season's greetings!
    2
  501. No real indications of that The issues in the Soviet system were generally overstated, at least in the sense that the quality and control issues (which there were), did not really change the overall combat viability of the force. Actually thinking about it, other countries have also had issues with workers at submarine yards etc. UK, US for sure
    2
  502. Thanks for watching!
    2
  503. no
    2
  504. I think that's RN. The USN system I think is "self-propelled submersible" Amounts to same thing, and anyway just "submarine" in normal terms
    2
  505. Appreciate it!
    2
  506. I appreciate that!
    2
  507. Thanks
    2
  508. i think I reference it at the end. Once only
    2
  509. Belgorod is massive, but only second largest ever after TYPHOON It is the largest built in 40 years, and will be the largest in service after last TYPHOON is retired
    2
  510. Fair enough I decided its better to use 'English' mispronunciations than hesitate trying to adjust. Same for most Russian ones etc. There's a certain city in Russia with a name I cannot say which comes up all the time
    2
  511. 3 / 3 are active at sea right now
    2
  512. Wow, thanks!
    2
  513. Belgorod also has regular torpedoes in addition to the Poseidon strategic weapons... yep, 533mm
    2
  514. real poster there was lenin
    2
  515. Glad you like them!
    2
  516. No, steel Last submarine constructed out of Titanium was Losharik. But there might be more in future
    2
  517. Thank you kindly!
    2
  518. I cover the pros and cons of X-form rudders here https://www.youtube.com/watch?v=qWeg7OCGw4Y
    2
  519. Try this https://www.youtube.com/watch?v=PdKkR_lbLN0
    2
  520. Yes verbal typo, Royal Navy
    2
  521. Thanks. But the point re this size is that it isn't because of any science reason like you describe. That's why I checked in with a lecturer on naval architecture. It was just that gradually torpedoes got bigger and eventually, around end of WW1, people decided that 21" was the most useful size because it was big enough to threaten any warship and had decent range. After that it was just the circular relationship of torpedoes and torpedo tubes
    2
  522. Brilliant, thank you.
    2
  523. Welcome!
    2
  524. They anticipate active sonar from all angles, but mostly the side. The missing ingredient is distance. For a submarine at 300m depth, the 'perfect angle' from above is approximately 400-200m away depending on exact angles of sides. That's really close.
    2
  525. Some subs use Kort nozzles but in general those are slow speed devices. They have a bigger gap between the shroud and the screw. Pump jets are much more finely tuned
    2
  526. I honestly don’t know. But the new Chinese Type-041 submarine has a ‘nuclear battery’ which is used like an AIP, with the traditional battery in reserve for when more power is needed, like a burst of speed.
    2
  527. Sorry about that
    2
  528. Glad you enjoy it!
    2
  529. Thanks. Proof https://youtu.be/PdKkR_lbLN0
    2
  530. Thanks!
    2
  531. For regular submarines they are going with ‘nuclear battery’ (aka tea kettle nukes) instead of lithium based technology, so different path to Japan and South Korea
    2
  532. Or, 21 real ones
    2
  533. Thank you
    2
  534. Hi, this does answer that. 533mm became the 'standard' in 1920s. It was never official though, just a default standard size. The first ones were earlier but from the end of WW1 onwards it was normal in almost every country (the exceptions are always interesting, but they prove the rule) Also, from 1800s until the creation of the USSR in 1917 Russia purchased torpedoes from the same manufacturers as western navies. There were local designs too in many countries, but ones like Whitehead dominated in Russia as much as anywhere else
    2
  535. Yes. Register it with your local authorities etc
    2
  536. The sonar pics I saw (likely same ones) were fake
    2
  537. Wanted to improve it. New to YouTube, learning you cannot edit after upload.
    2
  538. Thank you so much
    2
  539. If you are American using American satellites?
    2
  540. That was the normal way of showing it at the time, even quite recently in fact. A yard is roughly a meter. Doing historical stuff, and for an international audience, inevitably gets messy with units of measurement
    2
  541. Oh, like this new video? https://www.youtube.com/watch?v=pY4apzIiDgk great call, thanks!
    2
  542. Thanks!
    2
  543. No, nothing. Except that the length of the torpedo tubes can influence which torpedoes are carried obviously.
    2
  544. Good question, I think it would still be too much. I added sonar and torpedoes just to make sure. Either way, human endurance on a single crew submarine would limit it
    2
  545. Oil, presumably HFO
    2
  546. Here's the news https://news.usni.org/2018/01/03/houthi-rebels-find-likely-u-s-navy-unmanned-underwater-vehicle
    2
  547. The drawing is based on analysis of the satellite imagery, some of which is shown in the video
    2
  548. Thanks!
    2
  549. They will be SSNs, possibly with cruise missiles but not SSGNs (although some might spin them that way)
    2
  550. Thanks, yes it is on the list. Here is an article I wrote on it http://www.hisutton.com/Spy%20Sub%20-%20Project%2010831%20Losharik.html Actually I have written a lot of articles on it, all over the place. Sarov, Poseidon, other Poseidon related subs, they are all on the long list of possible videos
    2
  551. .50cal Barretts are used from helicopters to fire warning shots and shoot the engines. Not the people obviously
    2
  552. Sea Doo
    2
  553. Yes, thank you! As I remember it, Lupis may have not been the original inventor. But he was a major part of it.
    2
  554. The KILOs? Yes
    2
  555. Do not think that it as ever actually happened
    2
  556. I don't think that the M Class was steam. great subs, very interesting and impressive in their own right
    2
  557. Yes the inner hull is round, just a regular submarine construction. The outer hull is flooded so not under pressure
    2
  558. rarely
    2
  559. Actually Typhoon is shorter than the popular stats of 175m. See a helpful video I did on submarine lengths https://www.youtube.com/watch?v=Mv2no93jgzU
    2
  560. Yes partly I expect, it was happening at the same time and surely influenced requirements
    2
  561. Thanks 👍
    2
  562. I think it was just the only modern heavyweight torpedo anyone knew the designation of. But this wasn't that. It's an electric powered heavyweight weapon, likely complements the Yu-6 thermal types
    2
  563. This video is quite good on the topic https://www.youtube.com/watch?v=hk-0qJXyido
    2
  564. That was unrelated. The missing Seafox was known, just consider it 'found'
    2
  565. Welcome aboard!
    2
  566. The tubes are basically the right size, but would need the fire control etc to be fitted to the submarine to connect to it. For example Egypt bought some Ming Class submarines off China and then modified then to launch American torpedoes.
    2
  567. Thanks you!
    2
  568. Hope you enjoyed it!
    2
  569. Glad you think so!
    2
  570. I do not think so
    2
  571. hi, I think that the Type-VII is well covered by others. Not sure that I would have anything to add. I tend to focus on the more obscure types and topics
    2
  572. Maybe one day. In the meantime, try this article http://www.hisutton.com/Guide-to-heavyweight-533mm-torpedoes.html
    2
  573. Exactly
    2
  574. In Yemen, the vast majority of Shia Muslims are Zaydi, while Iran is Twelver Shi'ia
    2
  575. There is zero chance of the ship only needing 2 extra months Both are likely not recoverable, per video
    2
  576. I am not a pro, just use whatever I have to hand. No editing, no scripting... sorry but all I have time for
    2
  577. They are, certainly in the sub world. I have a lot of time for Swedish submarine history and design
    2
  578. Pr.971 AKULA Class, which is the one shown, has a single screw Pr.941 TYPHOON Class, aka Akula, has two with shrouds
    2
  579. Hi, yes I think you are correct. The damage is on the trailing edge not leading edge. I just noticed it at the last moment before the video and thought it would be useful weave in blade damage, which is also a real problem for certain submarines. Less SSNs which cannot bottom obviously. Actually I suspect that the screw is off К-324 after its collision with the towed array but cannot be sure. Anyway, I spoke to quickly, should have looked more closely.
    2
  580. @15.12
    2
  581. Thanks
    2
  582. Thanks, will do!
    2
  583. good question, don't know. Do not think so tough.
    2
  584. Yeah sorry, price of "unscripted and unedited"
    2
  585. check the author of that article
    2
  586. Yeah they are technically impressive, but limited use.
    2
  587. You're welcome!
    2
  588. Someone like Aaron at SubBrief might be better placed on Sonar
    2
  589. This is possibly a topic for another video. Here is why... Reporting names started in the Pacific theater in WW2, mainly for aircraft. The basic reason is that we are often talking about the submarine Before we know the home country's name. Even before the home country has decided on a name. In the 1990s-2000s, when NATO and Russia were on friendlier terms, some of the reporting names were chosen along a different pattern. Eg Severodvinsk Class. These names tend to be too long and generally harder to work with to be honest. People in the community call it Yasen (Russian) or Sev. The TYPHOON name has a specific story. That was what Soviet Leader Leonid Brezhnev called it during talks with US Secretary of State Henry Kissinger. See http://www.hisutton.com/The%20REAL%20Red%20October%20-%20Typhoon%20SSBN.html
    2
  590. Great line of thinking. I don't think it was a major factor, I didn't find arguments like that at all. But then I didn't find arguments at all really. But it is an advantage for 533mm tubes I do think that range and warhead were the driving factors
    2
  591. Good point.
    2
  592. With permission of course!
    2
  593. Influenced by it and borrowing some tech, but not really a copy
    2
  594. Agreed, I think I included it in a video on underrated subs
    2
  595. Thanks. Mention it just because otherwise I get a ton of comments from people who care about mics more than content. Trying to reduce that
    2
  596. It's Yantar
    2
  597. It is being reposted various places. As I understand it, originally appearing in Ru sources. Parts of it are at the beginning of this Instagram post for example: https://www.instagram.com/tv/CpKnYTxo3G5/
    2
  598. Ukrainian maritime drones (USVs) have been incredibly successful.
    2
  599. That's the A-26 class. Official artwork, the submarines are still under construction. See http://www.hisutton.com/A26.html
    2
  600. Thanks, was not aware of that
    2
  601. ?
    2
  602. Happy holidays!
    2
  603. ?
    2
  604. Double, although French and German designed single-hull boats are also present
    2
  605. Russia has been known to use their AK630s on surface targets during live firing exercises
    2
  606. All reasonable points, but sticking to Biber. Saying it could have been fixed, when over 300 were built... Far from a fan of Marder in this sense, many of the issues were shared (plus Molch, Delfin, Hai etc)
    2
  607. Yes. But it seems that they are discontinuing those.
    2
  608. Try twitter Naval aspects (mine) https://twitter.com/CovertShores OSINT gathering https://twitter.com/RALee85 Losses counting and monitoring https://twitter.com/oryxspioenkop More monitoring and counting https://twitter.com/UAWeapons Quality observations on land warfare https://twitter.com/WarintheFuture Many other accounts too, but those are the obvious one for this war
    2
  609. Doubt he's even heard of me. He does fantastic videos
    2
  610. If you are going to run the AIP, it is more efficient to use it to directly power whatever you need power for
    2
  611. Yes, in some respects sad to see her end, but a sinkex is a much better way to go than the scrap yard.
    2
  612. There have been quite a few submarines with external tubes. The main challenge is that you cannot perform maintenance on them while underway. As weapons move towards zero-maintenance rounds, we might see them coming back.
    2
  613. Very few at the moment, although the Cos.Mo.S MG-110 is an example Daphne was the last major class I can think of. Belgorod is the next major one, but special case applies. See https://www.youtube.com/watch?v=96ieEd-wTCo however, I look at a lot of submarine designs around the world and it frequently comes up, especially for smaller boats. Most of these designs never get built, but that's not because of the torpedo tubes. VLS / slant launch tubes on various classes are effectively this, just with missiles not torpedo's. Overall most navies think it is preferable to have a torpedo room. But the variables at play are likely to move, slowly, towards more external carriage in pre-sealed tubes.
    2
  614. Oh! apologies @hushkit6817
    2
  615. No, although there have been surfboard based USVs and larger USVs, like small speedboats.
    2
  616. Glad you like them!

  617. You are welcome!
    2

    2
  626. thank you
    2
  627. You're welcome
    2
  628. Does the flooded outer hull have to be reinforced for deep diving? Many deep diving subs have lightweight outer hulls, and NR-1 was single hull
    2
  629. Aye. The main sonar was in the leading edge of the sail for the earliest iterations with the rotary launcher As built, the A-11 had a conformal array in the bow
    2
  630. thanks!
    2
  631. Only one design can really be tied to Russian engineers and that was 20 years ago. There was a notable tech exchange with the Tamil Tigers (of Sri Lanka) c2007. But basically these are home-grown designs in Colombia
    2
  632. The superstructure is forward, it's listing to starboard. Agree re stability, cannot have helped.
    2
  633. I think they are letting it burn after the attack, but unlikely as a deception
    2
  634. Assad?
    2
  635. In general, I expect 533mm TT to be used mostly. But it is a fair point. Some tiny UAVs via external tubes, like countermeasure tubes, too.
    2
  636. Happy new year!
    2
  637. The main factor is to allow the crew to perform maintenance on the torpedoes while underway. In the future, with possible 'zero maintenance' weapons, we might see an increase in external carriage like you imagine
    2
  638. It means shark
    2
  639. Thanks for watching!
    2
  640. Glad it was helpful!
    2
  641. thank you!
    2
  642. Of the titanium hulled boats, I can only think of the MIKE class sinking. And that was caused by a fire.
    2
  643. I do my best
    2
  644. Cool, thanks!
    2
  645. Cheers!
    2
  646. Thanks!
    2
  647. A few inches. There are guide rails etc however, so still the case that a 21" tube isn't designed to shoot any larger diameter weapon.
    2
  648. Maybe, but I think overall people make too much of a connection. It is like the Poseidon gave defense writers an opportunity to show they knew of some obscure cancelled weapon from the past. I guess I am guilty too.
    2
  649. Was about to correct you then,.. oh

    1
  657. Glad you enjoyed it!
    1
  658. no i think that's not a launch rail for ordinance
    1
  659. Poseidon lacks the sonar to do that and anyway is carried by a host submarine until launched. So overall I think this scenario is one of the less likely ones

  674. Thanks, fixed
    1
  675. Yeah good point. Obviously those were shot from regular 533mm tubes, I mentally lumped them with the 533mm weapons, just more clearance. Was it ever intended to have a different size torpedo tube?
    1
  676. great!
    1
  677. There is also the Barracuda DE and KSS-III/DSME-3000 designs to consider.
    1
  678. You are welcome
    1
  679. Exactly, increasingly common for vessels which need to 'hover' like this. I just thought it would be interesting to point them out to people. They are rare on Russian intelligence ships and were ultra-modern for a naval vessel when she was built. Of course, they are rare on naval vessels, it's a compromise
    1
  680. The ideal with these submarine's screws is to run them as slowly as possible to reduce / avoid cavitation. Steel submarines generally use bronze screws
    1
  681. Lol
    1
  682. There were challenges making large enough diesels. Germany was ahead of Britain for this, so HMS X-1 which was the follow-on cruiser submarine after the K-Class, used captured German diesels.
    1
  683. Thank you very much
    1
  684. Not quite. These are illegal because they are unflagged, i.e. not registered wit any relevant authority.

  691. It's Pr.971 AKULA, not Pr.941 TYPHOON
    1
  692. Thank you!
    1
  693. A lot of people felt that way. The thing is, they really are doing what it said on the slide, at massive expense, so it is not 'fake news'. Your question becomes, what else are they doing? Well they have a whole bunch of these super weapons'
    1
  694. I don't think NATO have given a codename for this one. If they had I'd use it
    1
  695. it is a single piece which moves forward to extend out the front. We have good satellite imagery of them, including sailing to/from this exercise
    1
  696. Thanks!
    1
  697. Yeah I just screenshotted that to show the interface, was happy enough with Turtle but agree
    1
  698. Thank you, I do some quick sketches
    1
  699. yeah not much improvement expected. So far RuN reacts to Ukrainian moves quite slowly and heightened alertness is short lived
    1
  700. Beware reputations
    1
  701. Glad you enjoyed it
    1
  702. There was some serious flirtation with using Silver-Zinc batteries in the past, thinking 1950s-70s. Ultimately Lead-acid won out as much more practical and cheaper.
    1
  703. Drachinifel makes great videos
    1
  704. Yes, that was part of what made it more interesting I think. It was a technology which Russia evidently mastered, which the West did not, partly because the consensus was tat it wasn't realistic at all, too difficult. Submarine construction is on a different scale to aircraft for example.
    1
  705. Are you in US? Wondering whether Caesar vs M777 because we are slightly different media bubbles? Agree re impact of Russian glide bombs but not sure they are iconic

  712. I had meant to mention that they are normally bronze, but forgot. Another hint that the screw is titanium is the absence of sacrificial anodes.
    1
  713. thank you!
    1
  714. Glad it was helpful!
    1
  715. Reasonable lines of thinking. Note tat most of these, even the fully submersible ones, are made out of fiberglass., Lathes aren't normally part of the required equipment. Also are on detail of snorkel. In these cases my assessment is more based on the actual propulsion. We only call them snorkel subs if they require the snorkel above water to move forward. Its a detail, which is not always evident, which is why we put them as a subset of FSV even though they are technically not fully submersible.

  719. The water in the tanks is counted in the displacement figures
    1
  720. Great suggestion! Was thinking the same. But long list of video ideas
    1
  721. We do, the smaller torpedoes at the end of the video are two examples
    1
  722. Would be beautiful. The Royal Navy submarine museum (https://www.nmrn.org.uk/visit-us/submarine-museum) has one, and the Swedish maritime museum at Karlskrona has a very similar boat. Modern applicability, close to zero
    1
  723. no
    1
  724. Happy holidays!
    1
  725. Looks like they are largely just reporting what I wrote in Naval News and using my illustrations without permission?
    1
  726. My personal theory is that it has as much to do with the design bureau as the requirements.
    1
  727. no, that is a different one
    1
  728. Of course! There are a few more dotted about
    1
  729. Glad you enjoyed it
    1
  730. Check out my video on titanium submarines

  737. Yep. Mostly people who comment without watching the full video I suspect ;)
    1
  738. Thanks
    1
  739. Ah, the Alfa class. That was still massively bigger than this, and used a nuclear reactor. Given the physical limitations on the electric motor in this sub, I doubt that it is a super-fast submarine. My Alfa class article and cutaway http://www.hisutton.com/Alfa_Class_Submarine.html
    1
  740. Wow, thanks
    1
  741. It's not
    1
  742. If it was launched from within range, although it would only be militarily useful if it hit a train or vehicle. The warhead on a Switchblade is tiny.
    1
  743. Yeah missed a golden opportunity for that one. Along with Ursa Minor
    1
  744. It's 533mm in diameter, just like pretty much all submarine launched torpedoes, per the video
    1
  745. The ROMEO uses the 'knife' stern with the rudder behind the screw(s), influenced by German WW2 subs
    1
  746. Much appreciated!
    1
  747. Glad you enjoyed it
    1
  748. Torpedo tubes have to be specially made for the submarine. They have to have a depth rating at least equal to the occupied pressure hull (in simple terms)
    1
  749. Yes I think that's possible.
    1
  750. Don't think so

    1
  760. yes, 100%. Maybe for another video
    1
  761. Yes, absolutely, using sonar and/or other inputs
    1
  762. Interesting idea. I think it could be done, but cannot see why it would be better than regular electric torpedoes. Certain submarines operate wire-controlled ROVs (remote operated vehicles) but not like torpedoes
    1
  763. yes, but still deconfliction going on
    1
  764. 2500m might be a tad deep

  767. Appreciate it!
    1
  768. China does on occasion move submarine from one yard to another while fitting out. The latest Yuan class boat for example. I do not view this as suspicious in this way, nor the fact it leaked
    1
  769. Per the video, this ship carries ROVs and crewed submersibles well able to reach 2500m
    1
  770. Pr.1135M KRIVAK-II Class frigate Pytlivyy has been operating in the Black Sea, particularly escorting high value Russian gov ships. It was there when Ukrainian USVs attacked Sparta-IV on Aug 18, and another USV action near Kerch Bridge on Sep 1 (unconfirmed). See timeline http://www.hisutton.com/Timeline-2022-Ukraine-Invasion-At-Sea.html

    1
  778. Yes. Additionally however the physical scale and nuances of submarine construction are quite different. Aircraft parts can be welded in a sealed camber for example.

    1
  837. Yes
    1
  838. Thanks, all good food for thought. I did give the treaties etc a cursory look in my research and like you didn't find anything mentioning torpedo sizes. Your points made me think though. Two counter points surfaced... a) if "sticking to existing torpedo sizes more important" then why not 17.7" (aka 18")? b) if many parameters are limited, we can expect to see more innovation in the ones which aren't. I don't think we can take the naval treaty era out the context, and along with several other major factors (lessons in WW1, suddenly limited budgets, unrestricted submarine warfare, the cruiser sub red herring...) is part of the picture.
    1
  839. Hey, thanks!
    1
  840. Wow, thanks!
    1
  841. This is definitely a consideration. Although many would see the cost battle as Li-based batteries versus AIP, not versus traditional batteries. Fuel cell AIP is very expensive. One side benefit of Li-batteries is that the cells can be quite small. This means that the overall battery can, potentially, be molded into convenient shapes, thus taking up less space in overall terms. And because they are smaller, they should be easier to remove pier side. This in itself saves money. In some cases submarines had to be cut open to change the traditional batteries which is a ludicrous hidden cost. Overall I think Li is here to stay, unlike Silver-Zinc was. And cost probably won't inhibit its adoption.

  857. Depends what their motive is. Their sub tech is based on building German 209/214 boats, but it's developing fast. The politics are complex with Türkiye and the rest of NATO.
    1
  858. ? what about? Carriers in desert?
    1

  884. Yeah there are a few stories of ways they proved Titanium, and several of them are probably true. The thing about it being the deepest diving was incorrect, per the video. In the years since we have had decent data from Russia on the specs of these boats and its depth was very respectable, but not the deepest. And it had never been thought to be literally the deepest diving sub, just deeper than other SS/SSNs etc. The MIKE Class which followed really was deepest diving of the SS/SSNs. That used a special ballast system to allow it. We don't see such systems on ALFA
    1
  885. The rubber isn't enough to prevent it. Currently only a few Russian subs are titanium.
    1
  886. On all these subs, the outer hull is also Titanium. Even inside fittings had to be Titanium Using different metals would induce corrosion

  896. "Mini-sub" was a term coined in the late 1940s (from memory), by the Aerojet company. It has become a general term for a small submarine. Whereas Midget Submarine is a term generally used for naval submarines which are quite small, but in relative terms to typical naval subs. In modern times, less than about 35 meters long, although that's not exact. So there isn't a clearly defined difference. However, in general 'minisubs' are smaller or less capable than midget subs. Turkish midget subs? There are several, interesting designs, but then all submarines are. See http://www.hisutton.com/World-Small-Submarines-Compared.html and http://www.hisutton.com/Turkish-Indigenous-Submarine-Designs.html Also see https://www.youtube.com/watch?v=GRs_MVkrapY for submarine types

    1
  906. Thanks. here is a summary I did of AUKUS https://www.navalnews.com/naval-news/2021/09/the-5-main-options-for-australias-aukus-nuclear-submarine-deal/ hopefully not too much reading! Active sonar spoofing? yes the topic is discussed Re UCAVs, I assumed that the original question related to full size UCAVs since it mentioned the I-400. Small UAVs or loitering munitions, yes absolutely. But not plane-like UCAVs. I have seen a small sub launched UAV, was very impressed
    1
  907. Yeah I cannot think of any books where that’s a focus, you are right. Thicker books by the likes of Norman Friedman and Norman Polmar I am sure must

  908. Ah, good question. I nearly touched on the Mark numbers but thought it would only confuse people. However, since you ask... The RN had separate Mark series for 18 inch (I suspect actually 17.7 inch) and 21 inch weapons. So the Mk.VIII in 18" is a different weapon than the Mk.VIII in 21".

  912. Thanks for your comment. To clarify, when the video says 5 types, it means types, or categories, not classes. Classes is something else and applies to naval submarines (and the definition and usage of 'class' varies between navies).

  913. Great, welcome. I don't have a definite answer, but I think you must be right, any rafting must have come during refit surely. The quieter Soviet subs came a bit later, one or a few of the VICTOR-IIIs, then the AKULA, SIERRA, OSCAR, TYPHOON generation

  932. A decent line of logic except for a few things to consider a) often the torpedo loading hatch is not a crew access hatch. And it could be larger if they wanted. b) another way to load torpedoes is through the tubes themselves. Ideally the tubes are above the water, but Iran for example loads some boats by floating the torpedoes into the tube with the help of divers. Obviously the breach end of the tube is closed until the muzzle end is closed and the tube drained. c) Crew hatches can be larger than 21" So overall I don't think the crew hatches was a driver even though it's a tempting idea at first glance
