[@Deamon93IT]

Considering that the JMSDF already pushed the boundary with the "multirole destroyers" carrying F-35s I wonder whether the future iteration of subs will feature VLS as well, like the most recent South Korean SSKs.

[@ブリ出世魚]

It is difficult to effectively damage Russia and China with a small number of conventional warhead missiles on a narrow diesel submarine. Japanese submarines are likely to continue to specialize in underwater warfare.

[@tesokaaita6049]

I'm Japanese, but I don't think a submarine-mounted VLS will be realized if you imagine from recent public opinion. Japan has abandoned its offensive power against other countries by the Constitution Therefore, there are no ground-attack missiles at this time. However, from the current situation where it becomes difficult to intercept enemy ballistic missiles year by year. Politicians are arguing about the pros and cons of possessing a preemptive attack on enemy bases, but there is probably no VLS that can easily carry out a preemptive attack because public opinion that avoids the revival of imperialism is predominant. think

[@xx_sasuke_xx8726]

its not that they want to push the boundary, there basically being forced because of disputes with korea and china and the threats they impose to japan, they have to be capable of defending themselves. Plus the izumo class is far from being anything like a aircraft carrier while korea and china threaten japan directly with nuclear and ballistic missile capabilities

[@solarissv777]

@@tesokaaita6049 I wonder if advanced Sam's like SM6 can be launched from the submarine VLS, to be later guided by some aerial asset via link 16. Basically making submarine a hidden Sam site on the cource of the enemy aviation/missiles, or an extension of Japan's f35 payload bays. IMHO such payload will still adhere to defensive nature of the Japanese navy and allow some possibilities that were unseen before, like making submarines able to fight back against asw helicopters and planes. Also it just so happens that SM6 were successfully tested as anti-ship ballistic missiles.

[@Heldermaior]

The Li-ion batteries they are using are probably solid ones. With glass as the medium. They are less prone to fires and smaller in volume though energy density is the same. The advantage is that you don't need the AIP to get weeks long dives and the Li-ion will provide more power so that the boat can go faster than 2 or 3 knots. This is a capability game changer for non nuclear submarines. They will be faster and able to sustain that speed for longer which will make their deployments more interesting as their deployment radius increases dramatically. No instead of creeping at 3 kts to your target area to achieve surprise you can probably cruise at 8 kts which will reduce the deployment tine to 1/3rd. As a corollary, safe lanes will no longer be safe as intercepts will be able to happen much further in.

[@suntzu1409]

[@magicstix0r]

Souryuu's proper pronunciation is with a long o, "sou" and roll the R slightly while trying to say "you" with slightly long u sound. The "ryuu" part is the hardest to say. Souryuu means "blue dragon" and all class boats are all named after mythological dragons. "Hakuryuu" = "White dragon" "Unryuu" = "Cloud Dragon," "Kokuryuu" = "Black dragon," etc... Taigei means "Big whale" and similarly all class boats are named after mythological whales. The 2nd in the class, "Hakugei" means "White Whale." The -shio class boats, like Oyashio, are all named after currents around Japan. Oyashio = "Parent current" Kuroshio = "Black current" Natsushio = "Summer current" Harushio = "Spring current" Uzushio = "Whirling current," basically "Whirlpool"

For their long-perceived simplicity (crudeness?) when given the opportunity, Japanese WWI subs were indeed sophisticated and effective. After all, the I-19 launched one of the most effective torpedo attacks in history (and the only perfect score for a 6-torpedo spread?) when she sank the carrier USS WASP, destroyer USS O'BRIEN and damaging the battleship USS NORTH CAROLINA in Sept 1942.

[@daes9401]

I don't know if anyone has mentioned this -- it's been a minute since the video came out -- but I believe the navy ensign has not changed. It's the army, or however they call it officially, war flag design that is slightly changed (fewer rays and a partial gold border).

Excellent Video!, Post-war Japanese military equipment has been a real interest for me. Although I'll have a nitpick is that the JMSDF Naval Ensign and the IJN Naval Ensign proportion-wise are identical, the JMSDF's sun isn't offset like it was shown in the video and should be the same as the IJN's but the colors shown seem to be accurate.

[@jebise1126]

on one hand japanese ww2 submarines are under rated but mostly because japanese didnt use those properly. more scout missions than organized attacks. also those were riveted not welded and were in that technology way behind other nations

[@HISuttonCovertShores]

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

[@zolikoff]

How is going from AIP to battery a "step up" or "beyond"? I don't see it. Sounds like a step back. What is the pro there other than perhaps ease of maintenance? It's still gotta be a bigger fire risk though.

The first two Oyashio class submarines have been converted for training. I'm rather surprised that the Japanese are moving away from AIP. I wonder if it's a noise issue or if they think they can get enough time on station and power with lithium batteries. I thought the ROK KSS-III class had lithium ion batteries.

[@valiant8730]

Stirling is noisy, low output and too bulky because of its LOX tank. Lithium-ion battery-only endurance is actually tripled than Lead Acid battery-stirling AIP, and also you don't need to pay a lot for building new AIPs.

[@kirgan1000]

@@valiant8730 Stirling is NOT noisy, but it have a low power output. Fine if you are a Swedish submarine travel around in the smale baltic sea. Not so good if you are a Japanes submarine who want to travel around in the Pacific Ocean.

[@z_actual]

Australia looked at this very carefully, because it was on our menu to accept AIP in the refit. When it came down to it, it just wasnt worth it. Collins discretion rate is so low it wasnt worthwhile Since the hulls had to be cut to insert AIP, that was a compromise. Lithium battery are also not without problems and not combat tested and after all we could have used the added displacement of a hull stretch for additional existing battery chemistry and been better off.

They build 1 sub a year, their max number was 18 I think which meant decommissioning at less than 20 years. They got around this by calling a couple of the earlier class training subs, usually 2. They have decided to increase the number of active subs now to 20 iirc, but with Chinese aggression I wouldn't be surprised if they extended that by keeping their subs in service for up to 30 years like other nations do.
