nah, I think starfleet is a multicultural group just like the federation, why else do we see so many aliens in starfleet. I think the main reason we don't see many alien or even non-English names is the RW fact that it is an American show. Although I don't think it's that uncommon for non English/human ships, The Akira for example is a Japanese name, then there's the USS Zapata, the Tian An Men, the Akagi, the Tsiolkovskii, the Honshu and a few other cannon ships that have non English Earth names, we've seen a few Alien names too; the Shir'kahr, T'Kumbra, T'Pau, Surak and the Sitak are Vulcan names used by Federation ships.
