Thanks for the reply.
A follow up… if I have a bunch of fighters in an adjacent land zone to the SZ where the transports are, it appears that those fighters cannot help defend the transports (and would require a destoyer to do so anyways) in the sea zone.
ALso having an aircraft carrier with 2 fighters (34 IPC!) seems like a huge investment, would 4 Destroyers be better? Just curious…
