The Space Launch System (SLS) rocket that NASA hopes to send its astronauts to the Moon, asteroids and even Mars with, could soon be getting a new high thrust engine as part of its booster configuration. In fact, the engine may not be new at all. This was after Dynetics and Pratt & Whitney Rocketdyne (PWR) announced its partnership to off the Apollo-era Saturn V F-1 rocket engine for the competition which initially involves bidding for a NASA risk reduction analysis contract.
In a press release statement accompanying the announcement, Ron Ramos, Pratt & Whitney’s vice president for Exploration and Missile Defense, noted the F-1 engines high thrust-to-weight ratio and good reliability as he said: “We offer a domestic booster design that takes advantage of the – more – flight-proven Apollo-Saturn F-1, still the most powerful U.S. liquid rocket engine ever flown,”
Flightglobal/Ascend previously noted that manned moon exploration rockets needed bigger rocket engines - mentioning that there was a dearth of US rocket engines in the correct size.
With the LOx/kerosene burning F-1 back in the game things now look very different. The Dynetics/PWR team proposes mounting two of the proposed 1.8million lb (8,000kN) thrust F-1 derived engines ...
