tell me what those planes did
the helldiver sunk the yamato
We don't have the Yamato, nor was it a significant factor in WWII. All it was was bragging rights.
B7A1s din't do much, being very late and in small numbers, but it was powerful and manueverable. The Tu-2s had widescale service and made thousands of attacks on German positions.
You might also like the Il-2's successor, the Il-10.
The Japanese fielded almost as many designs as the US becasue they also had the Army/Navy split that we did, but look at the relative size of the planesets. Sure, you can argue "what did any of them do?", but in that case why have any German or Japanese aircraft, they lost the war so obviusly they didn't do anything....
