TheSoyuz-U2 (GRAU index11A511U2) was aSoviet, later Russian,carrier rocket. It was derived from theSoyuz-U, and a member of theR-7 family of rockets. It featured increased performance compared with the baseline Soyuz-U, due to the use ofsyntin propellant, as opposed toRP-1 paraffin, used on the Soyuz-U.^[1]

The increased payload of the Soyuz-U2 allowed heavier spacecraft to be launched, while lighter spacecraft could be placed in higherorbits, compared to those launched by Soyuz-U rockets. In 1996, it was announced that the Soyuz-U2 had been retired, as the performance advantage gained through the use of syntin did not justify the additional cost of its production. The final flight,Soyuz TM-22, occurred on 3 September 1995 fromGagarin's Start inBaikonur.

The Soyuz-U2 was first used to launch fourZenit reconnaissance satellites, then it delivered crewedSoyuz spacecraft to space stationsSalyut 7 andMir: missionsSoyuz T-12 toT-15 andSoyuz TM-1 toTM-22. It also supplied the stations withProgress cargo spacecraft:Progress 20 to Salyut 7,Progress 25 to42 to Mir, followed by the new generationProgress M-1 toM-18 and finallyM-23. Other missions included theGamma telescope and threeOrlets reconnaissance satellites. In total, Soyuz-U2 was launched 72 times and experienced no failures over its operational lifetime.^[2]^[3]
