Alliance cruisers possess more firepower than a frigate and more maneuverability than a dreadnought and form the backbone of the Alliance fleet. They lead frigate "wolf pack" flotillas.
Systems Alliance frigates, named after the great battles of human history, are among the larger warships capable of traveling between star systems in the interactive world of Mass Effect. Smaller combat support craft, fighters, and interceptors are used in a support role to the warships during combat. Fighters are a one-man craft used to perform close-range attacks on enemy ships. One of these is the SX3 Alliance Fighter.
