The idea of a cruiser was not as a military vessel, but rather a mobile research station, or "Science Cruiser" and this is still open and mallable. But it wouldn't be hard for Outcasts to worm in some fighters and bombers when New York is plagued by Tridentes.
Sigmas and Taus would also be an option, however. Yes, nerfing down the bomber amounts would be a better idea. 5 bombers could destroy even a battleship escort.
