Excalibur-class isn't actually one of Pat's - it's an old SFM mesh, though I can't remember the exact credits. The Hyperion-class was originally for the Arizona-A; The Pathfinder-class Miranda was of course the title ship of the sim, but so was the Jupiter-class - that class was originally created for the Miranda-A. Incidentally, the Miranda originally was a Kelvin-class ship - think a Soyuz-esque Sovereign. Pat had a habit of blowing ships up when he got bored with them. Even the Miranda-B got pretty badly beaten down once so that he could redesign her.
