A Russian ship captain would probably be pushing things a bit far.
Why in the world would you think that? We've already had a canonical Russian admiral, Alynna Nechayev. Presumably she was a captain at some point. And there was a Captain Krasnovsky on the hearing board in TOS: "Court-martial." There have also been quite a few Starfleet vessels with Russian names, like the Potemkin, Tsiolkovsky, Prokoviev
, and two shuttles named Tereshkova
, not to mention an entire Korolev
class and Soyuz
In the Borg
computer game there's a Captain Nikolai Andropov. In Trek Lit, there are numerous Russian captains. One I created (or based on a barely-glimpsed extra) is Claudia Alisov of the USS Everett
in my DTI novels. Memory Beta's list of Starfleet captains
includes quite a few other Russian names along with a wide mix of other ethnicities and nationalities.
