Washington DC - The US Air Force will consider a supersonic engine among three propulsion options now under review for the long range standoff (LRSO) missile, according to an acquisition notice released on 26 February.
The LRSO is expected to replace the Boeing AGM-86 air launched cruise missile, a subsonic weapon powered by a Williams F107 turbofan engine.
The USAF is considering two subsonic engine options – a derivative of an existing engine with 5% greater fuel efficiency and an advanced engine offering up to 20% better fuel efficiency, according to the request for information released by the LRSO branch of the Air Force Life Cycle Management Center.
A third option under review is a supersonic engine that would be sized comparably to “existing small core expendable engines”, the acquisition document says.
