Except for colony ships (CL-R, CL-G, CL-I) i use HP Lovecraft mitolgy names, so then, Shub-Niggurath (aka the Black Goat with a Thousand Young) is usually the name for a fighter carrier or a troop transport, Baoht Z'uqqa-Mogg (aka the Bringer of Pestilence) could be used for a Plague Bomb Ship or a Boarding Ship. obviuosly, Cthulhu is seldom used and hides an minesweeper or so
