- AR1 is designed by the company that has been involved in more than 2,100 successful launches, including every astronaut launched from U. S. soil.
- The AR1 employs advanced, highly-efficient oxygen-rich staged combustion engine technology that Aerojet Rocketdyne has continuously evolved for more than 20 years.
- Rapid development and certification of the AR1 is underway at the company’s premiere propulsion and innovation centers with delivery of a flight-qualified engine ready for launch in 2019. This results in a low-risk transition to affordable production using a known supplier base and a proven and skilled workforce.
- The AR1’s flexible, modular design allows the engine to be configured to support multiple launch vehicles, providing a U.S.-designed and manufactured propulsion system for the nation's most reliable launch vehicle that can be easily adapted to power other current and future government and commercial launch vehicles.
The only engine that is a direct replacement for the Russian-made RD-180, the AR1 is built by the company that is synonymous with the U.S. space program from the very beginning.
