USS Tereshkova (NCC-637) was a Gagarin-class science scout active in the 23rd and early 24th centuries.

In 2284, Tereshkova, commanded by Captain Corinne Morgenthau, and the hospital ship USS John Mandeville assisted a disabled Trill science ship. (Star Trek: Shadowstar Station: "Rescue the Perishing")

Tereshkova discovered an abandoned Romulan science station close to the Federation side of the Neutral Zone in 2285. A boarding party found ancient documents purporting that the Romulans' cloaking device (known to the Federation for about 20 years) had originally been discovered in a "stasis box" created by the billion-years-gone Slaver Empire (Star Trek: Shadowstar Station: "Hegemony", Operation Blackjack).

In 2286, Tereshkova discovered a lost Earth colony on Califia Prime in the Triangle (Star Trek: Shadowstar Station: "Center of Attention"). Later that year, Morgenthau transferred to Starbase 41 to become its chief science officer.

T'Siena, a Vulcan xenobiologist, was assigned to Tereshkova from 2300 to 2302, then transferred to the USS Avenger. (Star Trek: Avenger: "The Circle")


Tereshkova was named for the first Terran woman in space, Valentina Tereshkova.
