"Aerojet Rocketdyne's diverse propulsion capabilities are critical to missions like this, trusted to not only assist with delivering the spacecraft to its final orbital destination, but also to keep it there, properly oriented, for its full intended mission life," said
"We are proud to be a long-time partner in ULA's Atlas V program and our team is especially excited about this system's role in protecting and improving the communications of our brave warfighters around the globe," said
"The proven reliability and success of the AJ60 Solid Rocket Boosters and the RL10 provide a winning combination of rocket propulsion, and we are proud to enable this technology that will support our troops at home and overseas," said
The five AJ60 SRBs were ignited at lift off, increasing the launch thrust of the Atlas V rocket by more than 1.9 million pounds. All Atlas V launches requiring extra boost performance have flown Aerojet Rocketdyne-produced SRBs and this particular flight includes the 49th Aerojet Rocketdyne SRB delivered to ULA last April. These motors have demonstrated a 100 percent success record in flight, having now flown 17 missions over the past 10 years almost to the day, since the first Atlas V launch with SRBs on
A single RL10A-4-2 engine delivers 22,300 pounds of thrust to power the Atlas V upper-stage, burning cryogenic liquid hydrogen and liquid oxygen propellants along the way. For more than 50 years, the RL10 has been one of
In addition to the five SRBs and upper-stage engine, 12 Aerojet Rocketdyne monopropellant (hydrazine) thrusters in four modules on the Atlas V Centaur upper stage provided roll, pitch and yaw control as well as settling burns for the upper stage main engine. Once separated from the launch vehicle, MUOS-2 will use 12 MR-103G 0.2 lbf and six MR-106L 5 lbf thrusters for in-flight maneuvers and final relocation.
Aerojet Rocketdyne manufactures the Atlas V Solid Rocket Boosters at its
Built by Lockheed Martin, MUOS-2 is a next-generation narrowband tactical satellite communications system that will provide mobile U.S. forces with reliable and secure global communication, including, for the first time, simultaneous voice and data capabilities.
Aerojet Rocketdyne is a world-recognized aerospace and defense leader providing propulsion and energetics to the space, missile defense, strategic, tactical missile, and armaments areas in support of domestic and international markets.
