I am not one to name specific ships or classes anything badass or non-descriptive, so it will be a tie between the Itettsu (named for "headstrong", Tyrell Badd's japanese given name), the first of my intel gathering furtive ships (didn't get to do much more than blow some swarm out of the sky), and the Legislacerator-class Diplomatic ships, which optionally had a bunch of box launcher fighters on them. I am not very good at this.
