  1. Joseph if you could afford something like this you could afford a house where this thing would be a good 3 or 4 rooms from the nearest person. And roommates? Hahaha... "Hey, nice to meet you.. any idea how large the dorm rooms are here?" "Yeah, about the size of that giant metal thing strapped to the top of your car..."

  2. I think it depends how much pain you are, people who are in agony generally lose any inhibitions and could not care less who is watching because it stops registering, the majority of women giving birth while not caring who saw the business end of the delivery is proof of this. However if you're injured but the pain is manageable then your mind will operate as normal and so the thought of a crowd gathering around you while you're in a vulnerable or crippled state would make you very anxious, even more so if you were not a fan of crowds to begin with.

  3. If it's not broken, don't fix it.

  4. When a US sub goes to alert status do they 'sound general quarters' as they do on your surface ships? I heard somewhere that US subs 'sound action stations' like we do in the Royal Navy but you only use it on your submarines. In the UK we were originally general quarters for both, then it changed to 'sound battle stations' around the first world war and today it's "sound action stations".

  5. Try a Vietnam War shower - wait for it to rain and hand out the soap.

  6.  @googleaccount4159  The cameras likely had the battery switched out by whoever set up the drill. The key to a drill is to throw the crew a curveball - you will never be fighting a crisis on a submarine in ideal conditions and improvisation is something you must get used to.

  7.  @Shmey  I remember that episode of Mayday, that plane never stood a chance once those oxygen generators ignited.

  8. Except the Seawolf-class was designed to be leagues ahead of the Los Angeles-class. The SOD for an LA-class is around 300m so they were likely tested to around 410m and, due to their lower grade of steel, estimated to crush by 500m or 550m.

  9. Heavy equipment is placed along the keel, on a diesel boat this would be the banks of batteries but on a nuclear boat I assume it's the gas bottles that store all of the compressed air.

  10.  @Badeumus  Except for the fact that it was. U-1206 being the submarine.

  11. And here is your corrections.... USS Toledo was one of the latest and last Los Angeles class subs built. Diving Depth nowhere near 1km - Standard operating Depth 300m - crush depth 50% beyond that Speed : rare reports of 55-60kmh in certain conditions

  12.  @googleaccount4159  If your sub has just been hit by a torpedo do you think there would only be a single crisis and then it's all fine and dandy again? Your first crisis is making the boat safe by sealing compartments. Your second crisis is stabilising the boat so that it doesn't drop below crush depth. Your third crisis is restoring main power so the boat can maneuvre. Your fourth crisis, etc, etc, Do you think when USS Essex was crippled by a kamikaze pilot in WW2 that that was the end of their troubles?

  13.  @googleaccount4159  You completely missed my point, dude. If you have spent 8 hours putting out fires then your fire extinguishers WOULD be empty. Just as if you had spent 8 hours hunting fires behind bulkheads your thermal camera batteries WOULD be dead. A stricken sub or ship has finite supplies of everything and once they are gone they are gone, then it's time to improvise.

  14. The USS Los Angeles was a Flight 1 688 designed in the 60's while USS Toledo was a Flight 3 688i from the mid-90's, very different submarines.

  15. Have to wait until it returns, if it's an attack sub they may try to get a message to it during one of it's check-ins and then arrange to have the person picked up (highly unlikely) but if it is a ballistic sub then they have no choice but to wait for the sub to come home at the end of it's patrol.

  16. That was the Typhoons, they had three of them built throughout the 80's but the end of the cold war made them obsolete so they cancelled the rest and mothballed two of them - they still have the last one in operation though. The submarine in The Hunt for Red October was a Typhoon, since the movie was made just before the cold war ended they had no way of knowing what the inside of one looked like but they did get the dimensions correct and the sub was incredibly spacious compared to western subs.

  17. Would be tricky to make space for them as that is a premium on submarines.

  18. Except you can't break the laws of physics, if someone knows the shape of an object and the material it is made from they can just calculate it's crush depth using maths.

  20. I would assume this is a Los Angeles class so just Google "los angeles class schematic", there's tonnes of different cross sections of the sub from over the years. I haven't looked for a Seawolf class schematic but I would bet there are some seeing as the first boat is 24 years old now.

  21. Control is the name of the compartment the captain and senior officers are in, it's similar to the bridge on a surface ship.

  22. A nuclear-powered sub will be almost constantly submerged, an air-independent-propulsion sub will spend most of it's time submerged, and a diesel sub will be about half-and-half with as much time on the surface recharging batteries as it does submerged using up the batteries.

  23. I'd want a VR treadmill to be more like a giant baby-walker, you know.. so you can sit down still. Gimme a seat suspended above an omnidirectional treadmill instead. And let me sit in it wearing just a nappy like a baby.

  28. The US has lost two nuclear submarines. The Russians might have played fast and loose with their designs (mainly to catch up with the US) but you sound like the US is infallible, it is not, USS Thresher and USS Scorpion are testament to that.

  29.  @oriontherealironman  I agree with that. Sadly submarines, like any industry, benefit from the tragedies that come before and the experience makes them safer.

  30. That's crazy talk! If the US had 10 million subs you'd be able to walk across them from Europe to the US! j/k

  33. The only communications that can reach a submerged sub are Very Low Frequency signals and if you thought 90's dial-up internet was slow you'd be very shocked by how slow VLF is. It takes several minutes for a submerged sub just to receive a short text message of a few hundred characters so anything like real time radio or the internet is a no go unless you are both on the surface and close to land. The movie Crimson Tide shows how slow VLF is when the sub's radio breaks half way through a transmission and so the crew only receive half of their orders.

  35. USS Toledo is a fast attack sub, not a ballistic sub, it's job is to hunt down the submarines with nuclear arsenals.

  37. You'd have to cut a hole in the top of the submarine for photosynthesis to happen.

  39. They do on modern subs, the Toledo is 30 years old.

  40. That's why we designed our Astute and Vanguard class subs with hexagonal hulls, in case they get beamed into space.
