Aerojet Rocketdyne (AR) is delivering new RS-25 rocket engine hardware from its U.S. facilities to certify its new production process and is getting ready for the next phase of testing. More than a decade after production was discontinued, the engine maker is setting up assembly lines for major engine components at facilities in California and Florida and working towards delivery of six new flight engines for NASA’s Space Launch System (SLS).
UPDATE: On May 1, Aerojet Rocketdyne were awarded a further $1.79 billion to add another 18 new engines.
