The Bell V-280 Valor Will Replace the Army's Legendary Black Hawk

On Monday evening, the Army announced Bell as the victor in the longstanding Future Long-Range Assault Aircraft (FLRAA) competition to replace the Army's aging fleet of Black Hawk helicopters, marking the branch's largest rotorcraft purchase in more than 30 years.

The FLRAA competition was supposed to conclude in June, but Army leaders announced that they needed more time to review the two competing bids; Bell's V-280 Valor and a joint Sikorsky-Boeing compound helicopter platform dubbed the SB-1 Defiant-X. In November, the Army said they'd released their decision by the end of the year, citing "quality control" and "due diligence" as the reason for the delay.

With up to $1.3 billion on the line under the current contract decision, however, it does seem likely that the Sikorsky-Boeing partnership will file a protest, potentially prolonging the timeframe between the contract decision and the program actually moving forward.

According to Bell, the V-280 Valor is an extremely capable tiltrotor aircraft that offers a combination of conventional helicopter and airplane capability sets. With a claimed top speed as high as 305 knots (originally 280, hence its name), or approximately 350 miles per hour, the Valor beats the Black Hawk's top speed by better than 100 miles per hour, alongside a high sling-load capability and the skill sets you'd expect of a tactical helicopter, like allowing troops carried onboard to fast-rope out of the aircraft while it hovers.

Bellís V-280 Valor Tiltrotor Picked As Armyís Black Hawk Replacement

After a thoroughly strenuous and lengthy period of flight tests spread over several years, the Army has chosen Bellís V-280 Valor advanced tiltrotor to replace the venerable UH-60 Black Hawk helicopter.

Dubbed the Future Long-Range Assault Aircraft, or FLRAA, Valor is set to enter service in the mid-2030s and eventually will supplant the Sikorsky-built helicopter that has served as the Armyís workhorse utility rotorcraft for more than four decades.

The initial contract award is $232 million and includes no actual aircraft Ė the initial contract covers Valor's final digital design that Bell has generated as a result of the aircraft's five-year-long flight testing period and development campaign, inclusive of Army requirements. The total award, with options for physical aircraft, runs to $1.2 billion and then to $7 billion to begin building out the fleet, according to  Maj. Gen. Robert Barrie, the Armyís program executive officer for aviation.

The award is a huge win for Bell. The company recently completed planned deliveries of the latest versions of the venerable H-1 family of rotorcraft to the Marine Corps, built the OH-58D Kiowa Warrior that the Army retired years ago, and, with Boeing, developed variants of the V-22 Osprey for the Marines, Air Force, and Navy. However, it currently has no other major production contracts on the horizon with the U.S. military. The company has invested millions into manufacturing and digital design capabilities in various facilities in and around Fort Worth and Amarillo, Texas.

Valor posted hundreds of flight hours in its flight test campaign and notched more than the 280 knots speed it was named for and designed to achieve. Conventional helicopters cannot get anywhere near that speed. In fact, the V-280, which is a demonstrator and not a finalized design for the Army, broke the 300-knot barrier in testing.

Valorís first flight occurred on Dec. 18, 2017, and has since logged more than 200 hours in the air and met a number of ambitious speed and agility goals set by the Army under the Joint Multi-Role Technology Demonstration (JMR-TD) program.

Bell flew Valor for three and a half years before grounding the operational prototype in 2021. Sikorsky and Boeing continued to fly Defiant, which was still performing data-gathering sorties as recently as October but lagged behind the V-280 in flight hours because of developmental growing pains associated with its rigid composite main rotor blades and transmission system. The SB>1 first flew in 2019.

On Monday, the Army announced that Bellís V-280 Valor has won the Future Long-Range Assault Aircraft (FLRAA) competition aimed at fielding a modern replacement for the legendary UH-60 Black Hawk helicopter. The contract award, potentially worth as much as $1.2 billion, will fund ongoing development of the platform heading toward a production contract worth tens of billions of dollars.

But many have voiced concerns about the Valor's ability to do the job... So we set out to find answers to your most pressing questions.
