The Soyuz was a manned Russian spacecraft in service with the Russian Space Agency in the 20th and 21st centuries.
In 2143, an assignment patch for Soyuz T-6  , a joint Russian-French mission, was on display in the 602 Club. (ENT: "First Flight")
A sketch depicting the Soyuz spacecraft was contained in the library computer on the USS Enterprise in 2254. (TOS-R: "The Cage")
It is unclear if this database image depicts the Soyuz-TM or Soyuz-TMA spacecraft, as both have a virtually identical exterior appearance.
