USS Iktomi
USS Tempest
USS Sabbath
USS Nemo
USS Jupiter
I like Tempest, I was actually going to suggest it myself. I like Shan as well but I think it would be better for more of a warship. Nimbus was, as Dylan said a failed experiment though I don't mind it.
Some of my ideas:
USS Indefatigable (named after a famous Royal Navy ship)
USS Euryalus
USS Invincible
USS Indomitable
These are all old Royal Navy ships who's name I like.
