SH4 contains several IJN heavy and light cruiser classes, such as "Mogami", "Takao", "Sendai" and "Agano". The "Ashigara" and "Tone" heavy cruiser classes are missing; of the battleship classes, "Nagato" is missing. To compensate, "Ise" and "Hyuga" are available as both full battleships and as carrier-battleships. Wonder what you could actually fly from them, though, never mind actually landing anything on their short flight decks.

I'd suggest converting a few merchantmen first before adding any warships, though- a few extra types would make a huge difference to the sim.
