Lockheed Martin’s Sikorsky unit is challenging the U.S. Army’s December 5th decision to award its Future Long-Range Assault Aircraft (FLRAA) contract to Bell and has filed a protest with the U.S. Government Accountability Office (GAO). The move was widely-anticipated. 

Bell had fielded and flown its V-280 tiltrotor while the Sikorsky-Boeing team offered the Defiant X based on Sikorsky’s X-2 coaxial compound helicopter technology. The FLRAA program was designed to produce aircraft to eventually replace up to 4,000 Sikorsky Black Hawks. The initial production aircraft are expected to be operational by 2030 and the entire program could have a value of up to $80 billion.
