Progress-M

Also known as Progress 7K-TGM

Progress M (, GRAU: 11F615A55), also known as Progress 7K-TGM, is a Russian (formerly Soviet) uncrewed cargo spacecraft used to resupply space stations. It is a variant of the Progress series, developed in the late 1980s as a modernized version of the Progress 7K-TG spacecraft. Progress-M incorporated improved systems derived from the Soyuz T and Soyuz TM crewed spacecraft. The Progress M-M (GRAU: 11F615A60) introduced further upgrades, including digital flight control systems replacing earlier analog systems.
