A Nebula-class Federation starship with an all-Vulcan crew under Captain Solok, which came to Deep Space 9 for repairs in 2375 and beat Sisko's team at baseball.
The USS T'Kumbra was a Nebula-class starship whose crew was made up entirely of Vulcans. Its captain, Solok, had been a rival of Benjamin Sisko since their Academy days, when he wrestled Sisko to defeat and then used the incident for years in papers arguing Vulcan superiority.
In Take Me Out to the Holosuite, the T'Kumbra puts in at Deep Space 9 for two weeks of repairs after months on the front line of the Dominion War, where the ship had earned a distinguished record. Solok challenges Sisko to a baseball game in the holosuite, having trained his crew as the Logicians.
The Vulcans beat Sisko's Niners ten runs to one, though the Niners' joy at scoring their single run leaves Solok baffled and annoyed.
