@verdebusterAP ''Cost effective doesnt factor in''
Why wouldn't it factor in? Do you even know the primary rationale for F-35, the so-called, 'JSF'?
''The CVNs can use Cooperative Engagement Capability (CEC) with F-35C, F-18s , E2-D and FA/XX''
FA/XX is another fool's gold; U.S. needs to fix the main problem plaguing F-35 first: Buggy software, and non-durable, too fragile stealth coating, causing severe downtime issues, and unsustainable operating cost.
''For LHA/D which operate away from CVNs, the VAWS with F-35B is literally the only option''
Like I had said, F-35b is not cost-effective. ROK MC originally had planned for LHA with F-35b, but recently canceled it. The main reason: F-35b unreliability, combined with non-cost effective military effectiveness.
F-35b is the most expensive, the least reliable, and the least effective, both for air superiority, and CAS. It should not have been born. Why does USMC need F-35b in the first place? Their primary mission is amphibious assault; they can call USAF/USN for air superiority. For CAS, all they need is Apache. F-35b was nothing more than a 'turf' fight that got out of hand. Shame on USMC for robbing the tax payers for the 'egg roll' contest.

@verdebusterAP Dude, you're only pointing out pedantic tactical metrics; one does not judge how the war is going based on temporary tactical reports, but in terms of grand strategy.
Zelensky canceled the election: he's lost the people of Ukraine. They lost faith in him.
''Zelensky Refuses To Hold Elections in Wartime Ukraine''
The vaunted Ukrainian counter-offensive was a pathetic failure. Ukraine cannot last even 6 months without the Western support; Russia doesn't need foreign support to continue the war.
Ukraine is now running out of manpower. Whatever army Zelensky has is untrained, unfit, and unmotivated. Notice Cappi who supports Ukraine, is AWOL on Ukraine for a while. No mention of canceling the election, either. The writing is on the wall.
Remember the battle of Buldge? A temporary tactical advance, and Ukraine couldn't even duplicate, just some raid, and you call that a proof of success! That's the sign of desperation, not confidence.

@davidgoodnow269 ''Hyok Kim How is exhaust going to be made undetectable? Even cold propellants, like CO², have to expand outward under pressure. That creates a point of high heat at the point of pressure release. Can that be concealed from view? Yes. But the more thrust you need doing work, the harder that is to conceal.''
You didn't read what I had said. The missile could turn off the engine sometime before entering the IRST zone, so that by the time it enters the IRST zone, the exhaust would be at an ambient temperature.
''A hyper-velocity anti-aircraft missile being stealthed from RADAR, easily! (The missile itself. The compression shockwave and passage of that missile, not if the opponent is even marginally technically competent.) The thermal signature? The thermal track? Not in an atmosphere!''
There has been a breakthrough recently. You are not up to date.
Google, 'jae won hahn, stealth'
''The closest you can get is a glide-and-maneuver phase, staggered with thrust phases.''
Which hypersonic cruise missile has that capacity?
''That is similar to what hypercavitating torpedoes have to do, and for the same reasons. That provides opportunity to use active countermeasures to destroy or destabilize or spoof the missile (or torpedo)''
Would it work against this torpedo?
'Report: South Korea Is Developing a Super Torpedo That Could Attack at 200 Knots'
''Anyone who can't lacks either imagination or mechanical, technical, abilities. Taking down a hypervelocity ballistic missile requires two things to come from, "We had that in the '70's," to, "This is easy." High definition RADAR has improved into the current 7th generation, and that gives the necessary tracking precision and reach; sufficiently focused power transmission at fast enough speed of three-axis motion with sufficient speed. That latter is within reach, of Korea certainly, but no one is even trying! Everyone is content with head-on intercept at very high cost, rather than pursuing systems capable of side-on or even chasing engagement using comparatively cheap reusable systems.''
Are you talking about hypersonic cruise missile, or hypersonic ballistic missile?
''This is why they fail. I have, in retirement, formulated six completely different intercept systems that are, all of them, capable of intercepting any existing or proposed aircraft or missile, all cheaper than any existing system, all within current reach, and all based on the basic facts I just handed you. So, do you have adequate (A) knowledge of the laws of physics, and (B) imagination, to guess at least one?''
Would your system work on metamaterials based stealth system like Jae Won Hahn's?

@davidgoodnow269 ''Oh, yes, this is a tremendously effective and cost-efficient use -- stealthing something that is stealthy in its behavior, and has a largely fixed and known environment -- but just like a missile can be tracked by the "bow wave" it creates in atmosphere, submarines can be tracked by the water they compress and roil even at depth, by rolling colder or warmer water and creating a track. Both of those are old, established, highly refined mature techniques. Move slowly and thoughtfully enough, and the submarine will remain undetected.''
ROKN had already claimed as much: Nuclear subs are quieter than most conventional subs, but less than the state of the art AIP subs. Btw. Not all nuclear subs are the same: PRC nuclear subs are notoriously louder than even 80s Soviet nuclear subs.
Still, nuclear subs have the advantage of range, and speed over AIP subs, but that advantage is shrinking gradually by the advances in technology, and new strategy of employing subs.
ROK has recently perfected autonomous mass production technology of big ships, even warships, including subs; they can produce high quality warships/subs faster than anyone in the world.
Also, there is pibot, A.I. pilot robot that can be programmed to operate, planes, MBTs, and even subs.
'World's first humanoid pilot robot 'PIBOT' operates aircraft using AI technology'
What I consider ROKN's future strategy involving subs would be mass production of autonomous mini-subs, both nuclear, using ROK's own SMRs for offensive, AIP for defensive primarily, but could be towed by either nuclear subs to open deep ocean, and/or quantum photonic engine.
'Researchers realized a near-perfect photonic quantum engine driven by superradiance'
I hear the talk from ROKN that some of the later variation of up to 8 aircraft carriers ROKN is going to have by 2050 might end up using quantum photonic engine as well.
Obviously, with autonomous subs, once commissioned, they would not have to return to the port, but stay dormant till needed for decisive action, giving huge advantage in mobility, response speed, and logistics.
'Anechoic tiles will be something to put inside a submarine, then.'
Columbia class is going to use it on outside; great for MIC, bad for USN, and tax payers.
''Defeating any single hypercavitating torpedo is easy, and fairly cheap. You use depth charges, because against surface ships that is cheapest and easiest to fit, and supercavitating torpedoes cannot travel on or near the surface, they have to use an inversion of the anti-ship missile track. When a depth charge strips the envelope from a hypercavitating torpedo, that torpedo hits an incompressible wall of water at whatever speed it is traveling. Against surface ships, the tactic is to deploy two hypercavitating torpedoes which herd the target against each other, and use the noise from those to conceal two homing/guided quiet torpedoes to get them in close, then go silent before a final dash. Due to dealing with three dimensions, you double those numbers against a submarine. Submarines have difficulty using depth charges, they use small guided anti-torpedo torpedoes for defense. All of that is fairly open-source, even beyond being simple logic.''
The super torpedo ROKN was working on is the more stealth, smarter, and longer range version of the Russian Shkal.
It would approach the enemy high value target using electric motor, for much of the path, using the aforementioned metamaterial stealth, and home in guidance, and once it reaches 'Can't miss zone using super cavitation', then only then the super cavitation would be activated for the final drive to the target.

@davidgoodnow269 ''''To clarify, the achievements of Jae Won Hahn's working group is very impressive. It is, in my own unhumble opinion, unlikely to be employable in the ways a certain brief article described, to conceal soldiers in treated field uniforms!''
ROK has already come up with something far more robust than that.
'Fully stretchable self-charging power unit with micro-supercapacitor and triboelectric nanogenerator based on oxidized single-walled carbon nanotube/polymer electrodes'
''To explain that, one needs only to have served in a military in the field! The U.S. Army issued field uniforms treated with a chemical to shield its soldiers from thermal detection, in the 1990's. That chemical was destroyed by heat, it could only absorb so much . . . and the Army made its soldiers iron their uniforms. The U.S. Army issued boots treated with silicone to waterproof them . . . and made its soldiers strip the silicone from the leather, because it prevents boot polish from sticking . . . and the Army wanted those boots to shine!
Washing any clothes treated with the described nano materials will gradually and progressively remove the nano particles from the fabric, probably very quickly, but maybe not if deeply bonded at the atomic level. It would then depend on chemistry, as to whether the nano particles have a preferential bond to the molecular arrangement of the fabric, or to the cleansers or even dissolved minerals.''
ROK is universal mandatory conscription for males. He most certainly served.
''But his work is that of the engineer, not the theoretician, and the subject at issue is one theorized since Intel began using carbon nanotubes to provide cooling for computer processors in . . . hmmm . . . the late 1980's or early 1990's, I think it must have been. Back whenever the Pentium 66 or 90 MHz Pentium processor came out, and you really could heat a cup of coffee on one! (Though that did kill the processor, usually.)
Many, many people filed grant proposals to be paid to contemplate other possible applications for the same, and related, effects. Like most theory, it is often so long after papers are written that an idea becomes achievable, that the papers are largely forgotten. But meanwhile, countermeasures are planned, resources allocated, grants issued, because the clock starts for use and countermeasure at the same time.
I.B.M. waits until technology advances to the producible before filing its patent applications, on theory and math often decades old. Just do read a few dozen I.B.M. patents on the U.S. Patent Office website and you probably will see examples of that. The U.S. military is, I used to find, generally about thirty years ahead of the civilian world. That has changed with the adoption of "Commercial Off The Shelf" (C.O.T.S.) systems starting about thirty years ago, with the end of the Cold War. In theory, that would mean that those military systems are now at best equalled by civilian. But the civilian development economy does not parallel, much less follow, the military development thinking. The results are quite disparate. Technology developed for banking was far superior to a certain purpose than military technology, twenty years ago. It completely lacks properties essential to military purpose, then and now. And so it goes. Civilian technologies repurposed to military use often saves money, but that which is designed from the start to meet an essential military need is going to either end up completely without equal, or else laughably inferior to a commercial product. You never know until they are side-by-side and under military use-case!''
In ROK, any technology that is exclusive to military use cannot be patented to private entities; it belongs to government, and any company making weapons related to that technology can use it freely.
Of course, the company/engineer who developed the process would gain a cut of the weapon finally selected by the government, even if another company developed the final product selected by the government using that process.
This gives the private entities incentives to develop original process without the fear of missing out profit, on the final product, and at the same time, making the virtual economy of scale possible, making R&D so much more effective and efficient.
