I think the upper limit on ships the game can handle depends on the players ability to keep track of ships. It's a simple, paperless, game. The combat resolution table allows up to 16 weapons on a single target, but a rocketship can have more then 1 weapon and weapons with strength greater then 1. There are simple rules for ace pilots and other crack crewbeings. There is no allowance for different weapons such as torpedos.
