The Bell V-280 Valor is a tiltrotor aircraft being developed by Bell and Lockheed Martin 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 Annual Professional Forum and Exposition in Fort Worth, Texas. The V-280 made its first flight on 18 December 2017 in Amarillo, Texas.The V-280 is designed for a cruising speed of 280 knots (320 mph; 520 km/h), hence the name V-280, 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). In one major difference from the earlier V-22 Osprey tiltrotor, 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. The wings are made of a single section of carbon fiber reinforced polymer composite, reducing weight and production costs. The V-280 will have a crew of four and be capable of transporting up to 14 troops. Dual cargo hooks will give it a lift capacity to carry a 10,000 lb (4,500 kg) M777A2 Howitzer while flying at a speed of 150 knots (170 mph; 280 km/h). The fuselage is visually similar to that of the UH-60 Black Hawk medium lift helicopter. When landed, the wing is more than 7 ft (2.1 m) from the ground, allowing soldiers to egress easily out of two 6-foot (1.8 m) wide side doors and door gunners to have wide fields of fire.
