A propulsion technology Aerojet Rocketdyne developed for the Defense Advanced Research Projects Agency's hypersonic missile development program, called Operational Fires, has undergone a second round of tests. The company said Tuesday it conducted cold gas tests of OpFires propulsion system components seven months after completion of subscale test firings.

Aerojet Rocketdyne has fulfilled its task to produce hardware necessary for the propulsion of the rocket that would send a crewed Orion spacecraft around the moon as part of NASA's second Artemis mission. The company said Monday it completed the RL10 and RS-25 engines for the Space Launch System in support of Artemis II, the second integrated SLS-Orion flight and the first lunar flyby with crew.

Aerojet Rocketdyne has completed delivery of a milestone 600th delivery of boost motor and divert-and-attitude control system to the Missile Defense Agency's Terminal High Altitude Area Defense program.

The Johns Hopkins University Applied Physics Laboratory has integrated chemical and electrical propulsion systems from Aerojet Rocketdyne into a spacecraft for NASA’s Double Asteroid Redirection Test mission.

Aerojet Rocketdyne has demonstrated the static fire performance of a new solid rocket motor designed to provide bolstered propulsion with reduced operational and production requirements.
