Aerojet Rocketdyne Powers WGS-10 Military Communications Satellite from Launch Pad to Orbit
- RS-68A and RL10B-2 provide propulsion for United Launch Alliance Delta IV rocket
- HiPAT™ rocket engine helps deliver spacecraft to its final orbital position
- Delta IV pressure vessels manufactured by
Aerojet Rocketdynesubsidiary ARDÉ

Aerojet Rocketdyne’s role in the launch began when a single RS-68A engine ignited to boost the Delta IV off the pad, providing more than 705,000 pounds of lift-off thrust.
Following separation of the upper stage from the launch vehicle, an RL10B-2 engine provided 24,750 pounds of thrust to power the Delta IV upper stage using cryogenic liquid hydrogen and liquid oxygen propellants. Different models of the RL10 have been in service for more than five decades with nearly 500 engines flown in space.
Twelve MR-106H 9-lbf reaction control thrusters provide roll, pitch and yaw control for the upper stage through payload deployment.

Following spacecraft separation, WGS-10 will carry out several burns using Aerojet Rocketdyne’s HiPAT™ rocket engine to raise its orbit from a geosynchronous transfer orbit to its final geosynchronous orbital position. The HiPAT™ rocket engine produces 100 pounds of thrust and has a 100 percent mission success track record spanning more than 130 missions, including all previously launched WGS spacecraft.
