Future Long-Range Assault Aircraft

The Future Long-Range Assault Aircraft (FLRAA) program was initiated by the United States Army in 2019 to develop a successor to the Sikorsky UH-60 Black Hawk utility helicopter as part of the Future Vertical Lift program. The UH-60, developed in the early 1970s, has been in service since June 1979. Like the UH-60, FLRAA variants would also serve United States Special Operations Command and the United States Marine Corps. Under the existing Joint Multi-Role Technology Demonstrator (JMR-TD) program, the Army has been gathering data from flying prototype designs that could fill the FLRAA role. The Army posted a request for information (RFI) in April 2019, which was intended to identify interested manufacturers. According to the RFI, the Army plans to bring the FLRAA into service in 2030, in anticipation of retiring the UH-60 after a 50-year life. On December 5, 2022, the Army selected the Bell Textron V-280 Valor powered by Rolls-Royce engines for the FLRAA contract award. The award was protested by the Sikorsky-Boeing team, however the Government Accountability Office denied the protest.
