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.
Was built for the Imperial Japanese Navy shortly before World War II. She and her sister ship, Musashi, were the heaviest and most powerfully armed battleships ever constructed, displacing 72,800 tonnes. Her design plans were based upon Japan's belief that a powerful navy was the key to controlling the Pacific Ocean.
