What if the Japanese battleship Nagato was reactivated and pressed into JMSDF service?

They used these for ASW into the early 1960s...

Just keep the ship around in limbo until the Korea War and all of a sudden "well we have to rearm the japanese/germans to keep the reds from conquering the world"

you know kinda of what happened otl

also obviously rename it something else if it brings too much bad memories

That implies the Japanese even want a rusted out, barely maintained, out of date hulk
 
Would it be good for close fire support of landing forces like the Iowa? Assuming it never ever has to fight another ship.
No it needs its own supply stream and has been rusting without support for 5 years..... any USN ship in a fit state from its huge reserve better.

As the OP, I imagined a scenario where the Nagato or a Yamato-class battleship sailing alongside the USS Missouri shelling the North Korean coast in 1950-51. Just a thought I had before.

Kinda bummed that will only happen in ASB scenarios.

I have been thinking about this scenario for quiet some time now. So basically at the end of the war, Japan still had a few ships such as unfinished battleships, carriers, and submarines at the shipyards at the time of the Empire's surrender to the Allies. All of these became property of the United States government. Many of these were scrapped or turned into target vessels for live fire or nuclear tests in the South Pacific.

But what-if in this alternate scenario, the U.S. does not destroy these ships and by the time China falls to Mao Zedong's communist army, these are reactivated in an earlier-established JSDF. The Nagato would then serve as the flagship of the JMSDF alongside the reactivated ships and donated landing ship tanks and patrol boats.

How would Japan's East Asian neighbors react?

Her steam plant is burned out by sulfur contaminated improperly refined oil being run through it. What is the value of a floating paper weight? It might be a war trophy on Lake Michigan, but we had laws about that nonsense act of hubris by then. Razor blades. Japanese citizens have to shave.
 
If for some reason the US wanted Japan to rearm, Nagato is probably the last ship that Japan would want to keep operationnal.

There are a few new carriers (Unryu-class), cruisers (like the Tone, Agano, and Oyodo classes) and submarines (I-201 class) that were either intact, not completed, or sunk in harbor and salvageable at the end of the war.

And that is if the US absolutely want Japan to use Japanese equipment instead of selling them surplus US Navy ships (either barely used or brand new, just do not cancel them (*) )

(*) at the end of the war, dozens of ships were cancelled after construction had started and were broken up on the construction slips.

And if it were it would be unlikely to be a BB. That is overkill for what China had. Probably 3-4 Baltimore Class cruisers, 5-6 Cleveland Class Cruisers and maybe a dozen Gearing Class destroyers and this is stretching it. This is more than enough to handle China .

Or the Soviets and the North Koreans for that matter. I wonder what kind of ships and subs both the Red Navy and the KPN had at this period. Where they a threat to U.S. and UN ships?

Would those Unryu-class, Tone-class, Agano-class, and Oyodo-class be of proper era for the Korean War?

The US would probably use Japanese equipment for studying.

They did. Learned some useful lessons (aircraft carriers and subs) and applied them. Oyoda took too much bomb damage to be of any use and she was a one of a kind wrong lesson anyway.
 
If the US wanted to keep the Japanese navy operating former IJN ships, the late war DE (Matsu and Tachibana classes) would be the ones to keep. They could keep their DP 5'' guns, replace their 25mm AA with a mix of 40mm/20mm, remove their 24''TT and add more ASW weapons (Limbo?/Hedgehog?) .

The lack of a reliable semi-auto slam feed and a good multi-band altitude lead predict fire control system (sometimes referred to incorrectly as a high angle director) limited the Type 89 anti-aircraft guns severely. The destroyers were also very small and somewhat unstable with poor metacentric heights. Acceptable maybe in a wartime emergency (See that US destroyer classes had the same design fault as to stability.) but I can see better uses of the Matsus and Tachibanas as razor blades.
 
A horribly obsolete man power sink that has next to no escorts and would be seen as a symbol of Imperial Japan. Unless MacArthur was even more bonkers, and insisted the Japanese keep the ship she's of no value to Japan save as a reminder of their military that just got defeated, her value is in the metal she's made of as scrap value, thats about it.

I can't see Nagato lingering on that long. Here's a good piece on her postwar state:


If there was a reason for Japan to have a big-gun ship in the Cold War era, then that same reason means the USN will be hanging onto its newer battleships. So what's the reason? Maybe the Soviets build the Stalingrad class battlecruisers postwar, and several are assigned the Vladivostok? Or the Soviets provide one or two to China in an act of Comintern friendship?

If the Japanese Maritime Self-Defense Forces do need big-gun ships, the US has other option. A good one that might keep the neighbors less panicked might be to transfer Tennessee and California

That's South Dakota at bottom right blocking the end of the drydock.

In reserve at Philadelphia, both are pretty modern with their wartime rebuilds, but only good for 20 knots; they would fit a defensive posture pretty well. I have read that West Virginia, with similar rebuild, was considered the equal of a new battleship in all aspects but speed. They would need an AA refit, probably modern 3in/50s in twin mounts replacing the 40mm Bofors. Electronics would need updated as well.

If it was felt the Japanese needed 16in firepower, both Colorado and West Virginia are in reserve at Seattle. Again, they would need AA and electronic updates, and the Japanese could rebuild Colorado to a more modern (even more modern than West Virginia) standard.

If there was a need for Japan to have a faster ship, another option would be Hawaii, laid up in Philadelphia as well.

Hawaii at right in the bottom right nest of cruisers.

Hawaii has the advantage of using the practically mass-produced powerplant of the Essex class carriers, so spare for her engineering will never be a problem.

My thoughts,

It would be better to just get ex USN DE. But if you had to keep IJN ships in service, they would be the ones to keep.

Allow JJMSDF Kumano Maru. aircraft transport/landing ship, be converted to an ASW carrier during the Korean incident. Allow a dozen or more C/D Class kaibokan to serve rather than Tacomas. Allow modernization with US guns, radar and sonar.

With the USN based in Japan, what more do they need.

If you need a 'large' ship use Sakawa.

How obsolete was the Nagato along with their other ships still in dry dock? Would it be better if the U.S. donated some of their mothballed South Dakota-class battleships instead?
Nagato was built in 1920 and was originally partially coal fired. Even after the rebuild she was slow, barely capable of 24 knots. She had no place in post-WW2 naval warfare except as a manpower intensive, mobile gun battery that would require numerous escorts.
 
Not wanting to sound controversial, but how about the already built Alaskas (Guam or Alaska herself)? No threat to the USN, but quite well equipped and barely used. A reasonable answer to a Stalingrad, if this was the rationale.

How big was the JMSDF at the time in terms of personnel. Crewing of larger ships is always an issue for smaller navies.
