The Northrop Grumman B-21 Raider is a heavy bomber aircraft under development by Northrop Grumman. As part of the Long Range Strike Bomber program (LRS-B), it is to be a long-range, stealth strategic bomber for the United States Air Force capable of delivering thermonuclear weapons.[1][2] A request for proposal to develop the aircraft was issued in July 2014. The Air Force plans to purchase 80–100 LRS-B aircraft at a cost of $550 million each (2010 dollars).[3] A development contract was awarded to Northrop Grumman in October 2015. A media report states that the bomber could also be used as an intelligence gatherer, battle manager, and interceptor aircraft.[4]

At the 2016 Air Warfare Symposium, the LRS-B was formally designated B-21 signifying the aircraft as the 21st century's first bomber.[5] Secretary of the Air Force Deborah Lee James stated that the B-21 is a fifth-generation global precision attack platform that will give the US networked sensor-shoot capability, thus holding targets at risk.[6] The head of the U.S. Air Force Global Strike Command expects that 100 B-21 bombers will be the minimum ordered and envisions some 175-200 bombers in service.[7] Initial operating capability is expected to be reached by 2030.[5][8]

In March 2016, the USAF announced several tier-one suppliers for the program, including Pratt & Whitney, Spirit AeroSystems, and BAE Systems.[9]

The F-35 program manager Chris Bogdan stated that the commonality of the B-21's engines should reduce the cost of the Pratt & Whitney F135 engine.[10] The B-21 will be designed from the start with an open systems architecture.[11]

In April 2016, it was reported that the U.S. Air Force Global Strike Command (AFGSC) expected the required number to increase to a minimum of 100 B-21s.[12]

In July 2016, the U.S. Air Force stated they would not release the estimated cost for the B-21 contract with Northrop Grumman. The Air Force argued releasing the cost would reveal too much information about the classified project to potential adversaries. The Senate Armed Services Committee also voted to not publicly release the program's cost, restricting the information to congressional defense committees over the objections of a bipartisan group of legislators led by the Committee's Chairman, Senator John McCain of Arizona.[13] Senator McCain's proposed revisions to the National Defense Authorization Act for FY2017 would have reduced authorization for the B-21 program by $302 million "due to a lower than expected contract award value," while requiring "strict...program baseline and cost control thresholds," "quarterly program performance reports," and "disclosure of the engineering and manufacturing development total contract award value..."[14]

On 19 September 2016, the B-21 was formally named "Raider" in honor of the Doolittle Raiders.[15] The last surviving Doolittle Raider, retired Lt. Col. Richard E. Cole, was present at the naming ceremony at the Air Force Association conference.[16]

The Government Accountability Office (GAO) released a report on 25 October 2016 that sustained the Air Force's decision to award the LRS-B contract to Northrop Grumman. Cost was revealed to be the deciding factor in selecting Northrop Grumman over the Boeing and Lockheed Martin team.[17][18]
