Aerojet Rocketdyne Gets Another $70 Million for AR1 and RL10C-X Development

Aerojet Rocketdyne, Canoga Park, California, has been awarded a $69,804,323 modification (P00014) to a previously awarded other transaction agreement (FA8811-16-9-0003) for the development of the AR1 booster engine and the RL10CX upper stage engine for the Evolved Expendable Launch Vehicle program.

…

The work on the AR1 is expected to be completed by Dec. 31, 2019, and the work on the RL10CX is expected to be completed by Dec. 31, 2021. Fiscal 2017 research, development, test and evaluation (RDT&E) funds in the amount of $63,014,148; and fiscal 2018 RDT&E funds in the amount of $20,000,000 are being obligated at the time of award.

I don’t remember RL10 being part of the previously-awarded EELV propulsion contracts. Wonder if that’s related to the recent announcements that both Vulcan and OmegA will use the RL10 as their upper stage.
