At L3Harris, we are redefining the boundaries of speed, precision and innovation in hypersonic propulsion and weapons system technology. As the Trusted Disruptor in the defense industry, we leverage more than 40 years of hypersonic technology research, ground and flight test experience and cutting-edge manufacturing techniques to deliver trailblazing solutions that ensure our nation’s dominance across all domains.
L3Harris has been a trusted partner in advancing hypersonic propulsion systems, including ramjets, scramjets and solid rocket motors. Our dual-mode scramjet engine technology is a game-changer, operating seamlessly as a subsonic combustion ramjet at lower supersonic speeds (Mach 3-5) and as a supersonic combustion scramjet at hypersonic speeds (Mach 5+). This innovation delivers lighter, more efficient and higher-performing propulsion systems for long-range missiles and reusable hypersonic cruise vehicles.
Our scramjet engines have set industry benchmarks. Notably, the groundbreaking X-51A WaveRider, equipped with our scramjet engine, achieved aviation history in 2010 with the longest-ever supersonic combustion ramjet-powered flight. Today, we continue to push the limits of performance, leveraging advanced manufacturing techniques like 3D printing to reduce production time by 75%, cut costs by 75%, and simplify designs with 95% fewer parts.
L3Harris specializes in designing and manufacturing advanced, highly reliable electronics, avionics, telemetry systems and warheads that are qualified for use on hypersonic weapon systems to ensure precision, reliability and mission success. Key capabilities include:
Our commitment to innovation extends to our world-class facilities. From Huntsville, Alabama, where we support advanced manufacturing for hypersonics, to Camden, Arkansas, where we develop large solid rocket motors, to West Palm Beach, Florida, where we design high-performance air-breathing propulsion systems, and Orange County, Virginia, where we perform hypersonic testing, L3Harris is investing in the future. By incorporating secure digital engineering environments and expanding our capabilities in high-temperature alloys for 3D printing, we are driving down costs and accelerating production timelines.
As the leader in hypersonic technology, L3Harris is dedicated to delivering solutions that meet the evolving needs of our customers. Whether it’s optimizing propulsion systems for rapid global reach or delivering integrated telemetry systems tailored to any platform, we are committed to ensuring mission success.

What is Hypersonics
Dec. 3, 2019 - Aerojet Rocketdyne, prior to being acquired by L3Harris, successfully completes tests of subscale OpFires propulsion system as part of a Defense Advanced Research Projects Agency (DARPA) effort to develop a ground-launched hypersonic missile for tactical use.
L3Harris completes a successful series of hot-fire tests of an advanced air-breathing hypersonic engine under the USAF’s MSCC program. Some of the camera titling has been removed for a clearer image.
OpFires' variable-range second-stage motor enables payloads to defeat targets across the medium-range spectrum. Its launcher assembly loads onto fielded transportation vehicles with the push of a button. (Lockheed Martin Artist Concept)
