TsSKB-Progress (RKC Progress)

JSC RKC Progress (Rocket Space Centre Progress, formerly TsSKB-Progress) is a Russian aerospace organization headquartered in Samara, responsible for the production of Soyuz launch vehicles and a range of Earth observation spacecraft. Formed through the merger of the Samara Progress plant and the Central Specialized Design Bureau (TsSKB), it operates under the Roscosmos State Corporation.

RKC Progress is the primary manufacturer of the legendary Soyuz rocket family — the world's most-launched orbital launch vehicle with over 2,000 launches since 1966. Soyuz variants include the Soyuz-2.1a, Soyuz-2.1b, and the upgraded Soyuz-2.1v (using an NK-33 first stage engine). Soyuz has served as the crew transportation vehicle to the International Space Station for decades and launches from Baikonur, Plesetsk, Vostochny, and the European Guiana Space Centre.

Beyond launch vehicles, RKC Progress manufactures Earth observation satellites including the Resurs-P series (high-resolution optical imaging) and Bion-M scientific spacecraft. The company is also developing Soyuz-5, a next-generation medium-lift rocket powered by the RD-171MV engine, designed to compete in the commercial launch market.

With over 2,021 rockets launched and 1,006 spacecraft placed in orbit through 2026, RKC Progress holds an unparalleled track record in global launch history.
