[ merged in 2013 in Aerojet Rocketdyne ]

Aerojet was an American rocket and missile propulsion manufacturer based primarily in Rancho Cordova, California, with divisions in Redmond, Washington, Orange, Gainesville (both in Virginia) and Camden, Arkansas.

Aerojet was owned by GenCorp. It was one of the rare companies that provide both solid rocket motors and liquid rocket engines. Its products include a range of motors, from main engines used on a number of NASA vehicles and ballistic missiles, down to station-keeping thrusters for spacecraft. The propulsion devices include rocket motors as large as the EELV Atlas V strap-on rocket boosters.

Aerojet provided almost all of the USA Army's tactical missile rocket motors. They develop and manufacture a range of air breathing ramjet and scramjet engines. They also do research in the area of electric ion and Hall effect thrusters.
