Progress 11 (Russian: Прогресс 11) was a Soviet unmanned Progress cargo spacecraft, which was launched in September 1980 to resupply the Salyut 6 space station.


Progress 11 launched on 28 September 1980 from the Baikonur Cosmodrome in the Kazakh SSR. It used a Soyuz-U rocket.[2][4]


Progress 11 docked with the aft port of Salyut 6 on 30 September 1980 at 17:03 UTC, and was undocked on 9 December 1980 at 10:23 UTC.[3][5]


It remained in orbit until 11 December 1980, when it was deorbited. The deorbit burn occurred at 14:00 UTC.[3][5]
