Aerojet Rocketdyne announced April 11 it has received an order from United Launch Alliance for 116 engines for the upper stage of ULA’s Vulcan Centaur rocket.
United Launch Alliance will not be using an upgraded upper-stage engine in upcoming Atlas 5 missions as the company investigates the source of vibrations seen during a May 18 flight.
ULA finally selects BE-4 engine for Vulcan, marking an anticlimactic victory for Jeff Bezos and Blue Origin (and another disappointment for Aerojet Rocketdyne).
Years of Pentagon and NASA investments in nontraditional manufacturing technology appear to be paying off as government contractors step up the use of 3D printed components in space systems.
Aerojet Rocketdyne and the U.S. Air Force have revised an existing agreement supporting development of a new large rocket engine to include work on an updated version of an upper stage engine.
United Launch Alliance has picked Aerojet Rocketdyne’s RL10 engine to power the upper stage of its next-generation Vulcan rocket, the second such contract Aerojet has secured in as many months.
A United Launch Alliance Atlas 5 rocket launched a classified payload for the U.S. National Reconnaissance Office Dec. 12 from Vandenberg Air Force Base, California.
