Just a few comments if you don't mind
(all just IMO its your AU)
Generally you have,
1) too big a range of weapons (IJN + USN + other) often in the same (or similar calibre doing the same job)
2) your ships are to advanced for date (and use systems that are to modern)
3) They are to big to fit (unless you radically change all the fleets in the world)
4) They are individually overweight and very tight.
Examples,(with numbers from above)
Arachne class
Type: 1930s light cruisers - Inspired by: Mogami class, tight already and now defiantly over 10,000t and still might not fit 16x6inch+ (3/4)
Kämpfer class - to early (2) Construction Period: 1935-1936 Number built: 100(Inspired by Sims class destroyer 37-40 Completed: 12
) , this ship is unique in that it has to few types of gun (no 2nd light guns)
Vostok CV - (4/3)+ why the 90mm (1)
Tesla class heavy cruiser - How much does she weight she is more BC than CA
(3+4)8, this also has way to many types of gun I count 8 ! (1)
Morskoye super BB - How much does she weight ! and she will still not fit everything and make that speed (30 or 36 ? Kn )
(3+4)8, this also has way to many types of gun mount I count 7 (1)
Overall you are building more than the USN +RN + (well the rest is really irrelevant but still to much for anything short of a world dominating empire) This will totally change history due to making all of WW2 at sea irrelevant.
(it would also be a good idea to put a full list of all the ships in one post to make them clear what and when they are built its hard to read at the moment with different version overlapping, you could edit the latest versions onto the first page ? )
