Progress M1 ( , GRAU: 11F615A55), also known as Progress 7K-TGM1, is a Russian uncrewed cargo spacecraft used to resupply space stations. It is a variant of the Progress spacecraft derived from the Progress M, modified to carry increased quantities of UDMH fuel and N 2 O 4 oxidizer for refueling the International Space Station (ISS). The Progress M1 entered service in 2000 and was retired from regular service in 2004. A further upgraded variant, the Progress M1-M (GRAU: 11F615A70), incorporating the digital flight control system from the Progress M-M was planned but canceled before entering service. The design reflected the needs of ISS logistics at the time, as the Space Shuttle provided large-capacity delivery of dry cargo and water but could not transport the hypergolic propellants required for the station's propulsion system. However, following the Space Shuttle Columbia disaster in 2003 and the subsequent grounding of the Shuttle fleet, ISS resupply priorities shifted toward increased delivery of dry cargo and water, as Progress became the primary cargo vehicle, contributing to the type’s retirement in 2004.
