In 2018, the program successfully conducted the weapon systems Critical Design Review, a comprehensive program-wide evaluation of design maturity, stability and risk. Northrop Grumman’s partners on the B-21 program include Pratt & Whitney, Janicki Industries, Collins Aerospace, GKN Aerospace, BAE Systems and Spirit Aerosystems.

The Air Force awarded the B-21 Engineering and Manufacturing Development contract to Northrop Grumman on October 27th, 2015.

The Department of the Air Force Rapid Capabilities Office leads the development of the B-21 Raider under the direction of the Under Secretary of Defense for Acquisition and Sustainment and the Secretary of the Air Force. The B-21 is being designed with open systems architecture to reduce integration risk and enable competition for future modernization efforts to allow for the aircraft to evolve as the threat environment changes. Additionally, it will be able to employ a broad mix of stand-off and direct-attack munitions. It will be nuclear capable and designed to accommodate manned or unmanned operations. The B-21 Raider will be a component of a larger family of systems for conventional Long Range Strike, including Intelligence, Surveillance and Reconnaissance, electronic attack, communication and other capabilities. Designed to operate in tomorrow’s high-end threat environment, the B-21 will play a critical role in ensuring America’s enduring airpower capability. The B-21 will form the backbone of the future Air Force bomber force consisting of B-21s and B-52s. The B-21 Raider will be a dual-capable penetrating strike stealth bomber capable of delivering both conventional and nuclear munitions.
