History Northrop Grumman
Northrop Grumman B-21 Raider

The Northrop Grumman B-21 Raider is an American strategic bomber under development for the United States Air Force (USAF) by Northrop Grumman. As part of the Long Range Strike Bomber (LRS-B) program, it is to be a long-range, stealth intercontinental strategic bomber for the USAF, able to deliver conventional and thermonuclear weapons. The Air Force intends the B-21 to replace the Rockwell B-1 Lancer and Northrop Grumman B-2 Spirit by 2040, and possibly the Boeing B-52 Stratofortress after that.

The classified Long Range Strike Bomber (LRS-B) program began in 2011, and the Air Force issued a request for proposal to develop a LRS-B aircraft in July 2014. A development contract was awarded to Northrop Grumman in October 2015. Boeing and Lockheed Martin, who submitted losing bids for the project, filed bid protests; in October 2016, the Government Accountability Office (GAO) rejected the challenges and sustained the USAF's decision to award the LRS-B contract to Northrop Grumman. The GAO report revealed that cost was the deciding factor in selecting Northrop Grumman over the Boeing-Lockheed Martin team.

The Air Force began planning for the B-21 in 2011 and awarded the major development contract in 2015. The B-21 is expected to make its first flight in 2023 and enter service by 2027

Program Cost

In December 2022, the cost of a B-21 aircraft was estimated to be $700 million; at the time, Air Force officials estimated that they would spend at least $203 billion over 30 years to develop, purchase, and operate a fleet of 100 B-21s.)

Production

By February 2022, six B-21s were under construction. The first B-21 was moved to a calibration facility the following month. About 8,000 Northrop Grumman employees had worked on the program with greater than 400 suppliers from at least 40 different states.

Planned role in fleet

The B-21 is slated by 2040 to replace the U.S. Air Force's 45 B-1 strategic bombers, which date from the 1980s, and 20 B-2 strategic bombers, which date from the 1990s. The B-21 may also eventually replace the B-52, which is slated to remain in service for many decades

Potential related projects

The USAF is also planning to acquire a new long-range fighter from its Next Generation Air Dominance program, known as the F-X or "Penetrating Counter-Air", to escort the B-21 deep into enemy territory and help it survive enemy air defenses and intercepting fighters

American reconnaissance satellites first spotted the advanced Soviet Su-27 and MiG-29 fighter prototypes in 1978, which caused concern in the U.S. Both Soviet models were expected to reduce the maneuverability advantage of contemporary US fighter aircraft.
