USS Tycho
From Star Trek: Theurgy Wiki
The USS Tycho was a 24th century Federation starship operated by Starfleet.
Wenn Cinn served aboard the Tycho before transferring to the USS Theurgy.
(It is not been revealed what class of starship the USS Tycho was, but it is mentioned in the TNG episode (Conspiracy) that took place in 2364 so likely that it was an early 24th century vessel such as an Ambassador, Constellation, Excelsior, Miranda, or New Orleans class.)
