map situation

Aircraft situation

ship's sunk

(I do believe at least one more Japanese carrier is sunk)
So far that's the situation I'm not entirely sure on how the Japanese eco is doing but otherwise the Japanese are in a great position for 43 as most of India is conquered and they have carrier supremacy for a time to come.
the rules can be adjusted as needed and PM me if interested.
