History Bell Textron Inc.
Bell V-280 Valor is a tiltrotor aircraft
The Bell V-280 Valor is a tiltrotor aircraft being developed by Bell Helicopter for the United States Army's Future Vertical Lift (FVL) program.The aircraft was officially unveiled at the 2013 Army Aviation Association of America's (AAAA) Annual Professional Forum and Exposition in Fort Worth, Texas. The V-280 made its first flight on 18 December 2017 in Amarillo, Texas. On 5 December 2022, the V-280 was chosen by the US Army as the winner of the Future Long-Range Assault Aircraft program to replace the Sikorsky UH-60 Black Hawk. As of April 2024, limited user tests are planned for 2027 to 2028 with the first deployment expected in 2031
Design
The V-280 is designed for a cruising speed of 280 knots (320 mph; 520 km/h), hence the name V-280. It has a top speed of 300 knots (345 mph; 556 km/h), a range of 2,100 nautical miles (2,400 mi; 3,900 km), and an effective combat range of 500 to 800 nmi (580 to 920 mi; 930 to 1,480 km). Expected maximum takeoff weight is around 30,000 pounds (14,000 kg). One major difference from the earlier V-22 Osprey tiltrotor is that the engines remain in place while the rotors and drive shafts tilt. A driveshaft runs through the straight wing, allowing both prop rotors to be driven by a single engine in the event of engine loss. The V-280 will have retractable landing gear, a triple-redundant fly by wire control system, and a V-tail configuration.

Although the initial design is a utility configuration, Bell is also working on an attack configuration. Whether different variants of the V-280 would fill utility and attack roles or a single airframe could interchange payloads for either mission, Bell is confident the Valor tiltrotor platform can fulfill both duties.

Special emphasis has been placed on reducing the weight of the V-280 in comparison to the V-22, which would reduce cost.
