Aerojet M-1 hydrogen-oxygen rocket engine
Aerojet's M-1 was a historically significant liquid-hydrogen/liquid-oxygen upper-stage engine for the proposed Nova launch vehicle. NASA's Rocket Engine Test Facility history describes a 1.23-million-pound-class M-1, combustion-instability testing, and program cancellation in 1966 before a complete flight engine was realized; no flight installation is asserted.

- Note
- NASA's Rocket Engine Test Facility history identifies Aerojet's 1.23-million-pound-thrust M-1 liquid-hydrogen engine for the Nova upper stage, records combustion-instability testing, and states that NASA cancelled the M-1 program in 1966 before flight use.
