[2] The aircraft was officially unveiled at the 2013 Army Aviation Association of America's (AAAA) Annual Professional Forum and Exposition in Fort Worth, Texas.

[3] 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.

[6] In June 2013, Bell Helicopter announced that the V-280 Valor design had been selected by the US Army for the Joint Multi-Role (JMR) Technology Demonstrator (TD) phase.

The Army classified the offering as a Category I proposal, meaning it is a well-conceived, scientifically or technically sound proposal pertinent to program goals and objectives with applicability to Army mission needs, offered by a responsible contractor with the competent scientific and technical staff supporting resources required to achieve results.

[16] In October 2013, the U.S. Army awarded a technology investment agreement (TIA) to Bell for the V-280 Valor tiltrotor under the Joint Multi-Role program.

The TIAs give the four teams nine months to complete preliminary design of their rotorcraft, which the Army will then review and authorize the construction of two competing demonstrators to fly in 2017.

[22] Announcement of the selections was officially made on 3 October 2014, and the teams began building technology demonstration aircraft for test flights in 2017.

It is focused on the infantry squad and is to handle much like a helicopter in terms of low-speed agility to have unprecedented pitch, roll, and yaw response for those operations.

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).

[50][51][52] 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.

The U.S. Marine Corps is interested in having one aircraft to replace utility and attack helicopters, but the Army, which leads the program, is not committed to the idea and wants distinct platforms for each mission.

[12] Features in the interior include seats that wirelessly charge troops’ radios, night-vision goggles, and other electronic gear and windows that display three-dimensional mission maps.

Wing skins and ribs are made of a honeycomb-stiffened "sandwich" construction with large-cell carbon cores for fewer, larger, and lighter parts.

At the same time as increasing power from 5,000 to 7,000 horsepower, the AE 1107 is a known element in tiltrotor aircraft with its two decades of prior use, which lowers sustainment costs and decreases risks of the project.
