My TEC ships use CSS prefix - Consortium Space Ship (as in ship that belongs in the Consortium space). As for the ships' names:
Kol Battleships: CSS Normandy, CSS Omaha, CSS Iwo Jima, ... (World War II battles)
Carriers: CSS Ohio, CSS Nebraska, CSS Virginia, ... (U.S. States)
Battlecruiser: CSS Cornwall, CSS Yorkshire, CSS Edinburgh, ... (U.K. place names. I dunno, I just get the image of British Navy destroyers in my head when using this ship)
Siege Battlecruiser: CSS Volgograd, CSS Rostov, CSS Voronezh, ... (Russian Cities)
Colony Ships: CSS Columbus, CSS Magellan, CSS Cook, ... (Explorers)
