Your Air Power is low for both carrier fighters and seaplane fighters.

MAX Iwamoto, Iwai, F6F-3's, T0FM21(S), T0FM52(S) and Zero M52C(601AG) to fill the void in your carrier fighters, that +2 AA bonus can really make a difference, especially in maps with high air power requirements.
 * Improve the Model 21 (Skilled), they can aid your Hayabusas on long-range missions.
 * You can also close the gap by MAXing normal Zero Model 21 and doing Conversion Quest F22 and F25. The Improvement will be carried to the Skilled Fighters.

Develop two more Type 2 Seaplane Fighters; and do Conversion Quests F51 and F52 so you can further improve them after doing the quests. Ro.44's can only get you so far.

I recommend you read these:
 * Small Savings For Improving Type 0 Fighter Model 21/52
 * Mitsubishi A6M Zero Fighter Conversion Quests
 * Type 2 Seaplane Fighter Kai (Skilled) Conversion Quest
