^I'm trying to create consistent naming styles. While they're not in the above post, I'm naming individual ships in the fluff as well. The Imerpium gets quasi-Latin, as it must. Things like IMS Periastron, Armentarius, and Ophiophagus. (Which is the Latin name for the genus to which Cobras belong. All the Cobras have gotten Latin snake names thus far. I do like to nest in some Easter eggs if I can.)
For the Rim gang I'm going with a system that derives mostly from US Navy practice, with just a touch of UK and French practice. Place names, people, concepts, mythological figures, and the occasional bit of mangled French out of respect to my English speaking city which cannot pronounce either its own name or those of its most ancient landmarks. Thus far I have things like TSS Blanding, Hirth, Achile, and Perun. (That last is a Slavic god of thunder, which seemed nice for what Citadel called a Thunderbolt.)
