I rarely play Vasari, so tend to enjoy naming my ships in a very human convention when I play TEC or Advent.
I used to prefix every name with EAS for Earth Alliance Ship, but found the characters that took up restricted what I could use for names.
I started off with my favoured route of Babylon 5-style mythical/classical history names, such as:
Apollo, Agamemnon, Cassius, Damocles, Kraken, Cerberus, Medusa, Gorgon, Chimera, Hydra, Griffon, Vesta, Juno, Ariadne, Alexander, Bucephalus, Wyvern.
In my view of space fleets, Battleships and Carriers are always the largest ships, even if they aren't in Sins, so my Kols/Sovas/Radiances will always be named one of:
Leviathan, Colossus, Behemoth, Titan, Zeus, Hades.
However lately I've had a bit of a penchant for some faux-classical names, as inspired by the genius that is Dan Abnett, and have been using the following:
Titus Invictus, Ajax Excelsior, Sicarea Faero, Imperius Rex, Deus Titanus, Brutitor, Raptorus Rex, Prince Manix, Augmenautus, Demos Annilus, Dominus Victrix, Imperius Dictatio.
To me, all these names inspire awe and pride in your fleets and allies, as well as fear and fealty in your enemies. After all, who wouldn't want to go to war accompanied by the majesty and power of the battleship Imperius Rex and her attendant escorts?
Alternately, which of the following messages would an embattled, outnumbered fleet admiral rather receive?
'Admiral, Sir, we're receiving a sub-space message, the carrier BigBoy is on her way!'
'Admiral, Sir, we're receiving a sub-space message, the carrier Leviathan is on her way!'
I know which I'd rather hear when enemy cruisers are bearing down on my position...
