The Aerojet M-1 rocket engine was to be a beast of an engine. Bigger than the F-1 with almost as much thrust, it differed in being fueled with hydrogen. Its intended role was to power post-Saturn “Nova” type rockets. It got as far as testing major components, but no complete engine was ever test fired. The need for such an engine went hand-in-hand with the development of very large boosters; the M-1 could have been used for either first stage or upper stages, but no booster sizable enough for such an engine survived the mid-sixties, so the M-1 died away.
