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.
Production of the GE T901 engine would also be delayed pending compatibility with the Boeing AH-64 Apache and Sikorsky UH-60 Black Hawk. [3] Development on the Future Long-Range Assault Aircraft (FLRAA) program and its winner, the Bell V-280 Valor, is continuing. [27]
In February 2022, Sikorsky-Boeing picked Honeywell's new HTS7500 engine, a derivative of the Honeywell T55 engine that powered the SB-1 demonstrator, as the powerplant. [24] In March 2022, Sikorsky-Boeing has selected Collins Aerospace to provide all three seating platforms and its Perigon as flight control computer .
Scott C. Donnelly, CEO of Textron, has said in April 2019 that the Bell 360 will be based on the Bell 525. [1] [2] The 360 and 525 will share an articulated rotor system, although the 360, which will only seat two (a pilot and gunner), will use a single engine and a four-blade rotor, whereas the 525 uses twin engines and a five-blade rotor and has a nineteen-passenger capacity.

The Boeing-Sikorsky team was selected to build the RAH-66 Comanche in 1991. [2] A pair of T800-powered RAH-66 prototypes were constructed and underwent flight testing between 1996 and 2004. The LHX program was canceled in 2004, primarily due to cost overruns during its lengthy development, and the US Army's changing requirements.
The tilt-rotor FLRAA demonstrator by Bell is flying unmanned (October 2019); it logged 100 hours of flight testing by April 2019. [97] Both Bell and Sikorsky-Boeing received contract awards to compete in a risk reduction effort (CDRRE) for FLRAA in March 2020. [98] [97] [99] The risk reduction effort will be a 2-phase, 2-year competition. The ...
The Boeing–Sikorsky RAH-66 Comanche is an American stealth armed reconnaissance and attack helicopter designed for the United States Army. Following decades of study and development, the RAH-66 program was cancelled in 2004 before mass production began, by which point nearly US$ 7 billion had been spent on the program.
The Boeing-Sikorsky design carried ordnance within upward swinging gull-wing doors in the sides of the fuselage and featured a fenestron tail rotor. The program's name was changed to Light Helicopter (LH) in 1990. [6] In April 1991, the Boeing-Sikorsky team was selected as the contest winner and received a contract to build four prototypes. [7]
