US Air Force Considering Saturn V F-1 Rocket Engine Derivative to Replace Russian RD-180s

A proposed U.S. rocket engine based on the iconic Apollo-era F-1 could replace the Russian technology found on many American military boosters, according to the firms behind its design.

What’s more, it could be compatible with both Pentagon and NASA rockets, so the same propulsion system that may someday send astronauts to Mars could also be used to launch military and spy satellites, they say.

The new engine, a liquid oxygen and kerosene-fueled system known as the AR-1, would be smaller than the F-1 that powered the Saturn V rocket, but have higher performance and provide some 500,000 pounds of thrust, according to Steve Cook, director of corporate development at Huntsville, Alabama-based Dynetics, which has partnered with Aerojet Rocketdyne to design the technology.

“Imagine taking a big old F-1 and being able to put it in a much more compact unit and get much more performance out of it,” he said in a telephone interview.

Under a contract for a program called Advanced Booster Engineering Demonstration and Risk Reduction, engineers at Dynetics in October 2012 began working on ways to lower risk — and thus cost — associated with building a future first-stage engine for the NASA’s Space Launch System, the rocket designed to carry astronauts to the moon, asteroids and eventually Mars.

One would think SpaceX would be a more appropriate company for partnership, as they designed, built and operated multiple LOx-kerosene rocket engines and currently plan to build a heavy booster engine with similar characteristics.
