The U.S. Air Force (USAF) will soon ask companies to propose new ideas for long-range hypersonic weapons that can be demonstrated rapidly.
The Air Warfare Directorate within the Air Force Research Laboratory (AFRL) plans to open the solicitation process within 30 days, an acquisition notice released Jan. 15 says.
The concepts call for weapons that can sustain Mach 5 speed and fly farther than 500 nm. Additional requirements and evaluation criteria will be detailed in the solicitation.
A vehicle capable of sustaining speed at Mach 5 or higher tends to refer to air-breathing propulsion systems, such as a supersonic combustion ramjet (scramjet), a rotating detonation ramjet or a turboramjet.
The selection process will begin with a request for white papers.
The proposed solicitation would continue a long series of hypersonic vehicle concepts sponsored by AFRL. The Boeing X-51A, which was partly supported by DARPA, demonstrated a scramjet-powered, waverider vehicle fueled by traditional kerosene nearly 13 years ago. Another project—a hypersonic strike-reconnaissance aircraft called Mayhem—was suspended in 2024.
