Someone Posted the Japanese is represented by 5 aircraft, while true - Val, Kate and A6m2 all represent PRE-1942.
It would be nicer to fill in the mid-late war slots with B6N and Judy dive bomber, Anything beyond Mid 1943 is not represented and leaving a huge gap in the lineup for PTO (naval wise).
Sea Hurricane would be a great addition only when the Hurricane gets upgraded, Seafire Mk III however would not likely be added any time soon.
Fairey Firefly is something I wouldn't mind added, its really a late war naval aircraft, it showed up in late 1944 (funny thing is it was designed in 43) - however it did some raids on Java and Borneo.
I would rather have the Seahurri and Japanese B6N/Judy added before anything else right now.
Seahurri is almost a must, being it served in every major theater of operation, and scored kills.
