Aerojet Rocketdyne Propulsion Powers the Fourth U.S. Air Force Advanced Extremely High Frequency Satellite Mission
Aerojet Rocketdynesupports the Air Force’s critical communications network, from the launch pad of United Launch Alliance’s Atlas V rocket to orbit to final end-of-life decommissioning of the satellite system. Aerojet Rocketdynechemical and electric propulsion onboard the AEHF satellites provide orbit raising, stationkeeping, attitude control, and repositioning capabilities.
- Compared to all chemical propulsion, AR’s electric propulsion results in a savings of more than 2,000 lbs. of propellant, reducing launch costs.

According to Lockheed Martin Space, “the AEHF satellite system delivers global connectivity and protected communications to national leaders and armed forces, 24 hours a day, through a secure constellation. Satellites are jam-resistant, highly-survivable and allow for critical information to be transmitted on ground, air and sea platforms.” This fourth satellite will round out the backbone of the network, which will gain another two satellites to complete the six-satellite system.
“Seamless and secure communication is vital to the effectiveness and safety of our servicemen and women across the globe,” said
