I usually run a 5:3 bomber:fighter ratio with a single carrier, 6:2 if I have more than one. The fighters are amazing dogfighters but too hopeless for anti-shipping to buy in large numbers, and the bombers are so slow and fragile that you have to use large numbers to get any through for a strike. Unless your opponent has never faced Al Malik bombers before, he will shoot the bombers to death ASAP, but they still serve a useful purpose that way - the shots needed to kill them are ones not hitting your gunships, which buys you time to gnaw on his ships.
