A US corporation whose space accomplishments include the Atlas and Centaur rockets, as well as the space shuttle's mid-fuselage. It has also contributed to the Hubble Space Telescope, the International Space Station, and the Mars Exploration Rover. The Atlas was created by General Dynamics Corporation's Convair Division as an intercontinental ballistic missile and was later modified for NASA's space programme. The Centaur rocket was developed by the Space Systems Division to launch the space shuttle and satellites.

The General Dynamics Corporation formed its Convair Division in 1954. In 1985 it separated Convair's space programmes to create the Space Systems Division. The latter was sold to the US company Martin-Marietta in 1994, and the Convair Division was disbanded two years later.
