Development

A request for proposal to develop the aircraft was issued in July 2014. The Air Force initial plans were to acquire 80 to 100 LRS-B aircraft at a cost of $550 million per unit (2010) and envisions some 175 to 200 to be in service eventually.[9][10] 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.

 

At the 2016 Air Warfare Symposium, the LRS-B was formally designated "B-21", signifying the aircraft as the 21st century's first bomber.Then-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 United States networked sensor-shoot capability, thus holding targets at risk. 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. Two internal USAF studies suggest that Air Force could increase its B-21 purchase from between 80 and 100 to as many as 145 aircraft.[16] Initial operating capability is expected to be reached by 2030.

 

In March 2016, the USAF announced seven tier-one suppliers for the program: Pratt & Whitney; BAE Systems of Nashua, New Hampshire; Spirit AeroSystems of Wichita, Kansas; Orbital ATK of Clearfield, Utah and Dayton, Ohio; Rockwell Collins of Cedar Rapids, Iowa; GKN Aerospace of St Louis, Missouri; and Janicki Industries of Sedro-Woolley, Washington.

 

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. The B-21 will be designed from the start with an open systems architecture.

 

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

The Northrop Grumman B-21 Raider is an American heavy bomber under development for the United States Air Force (USAF) by Northrop Grumman. As part of the Long Range Strike Bomber program (LRS-B), it is to be an advanced very long-range, large, heavy-payload stealth intercontinental strategic bomber for the USAF, able to deliver conventional and thermonuclear weapons.

The bomber is expected to enter service by 2025. It is to complement existing Rockwell B-1 Lancer, Northrop Grumman B-2 Spirit, and Boeing B-52 Stratofortress bomber fleets in U.S. service and eventually replace these bombers

Maintenance and sustainment of the B-21 will be coordinated by Tinker Air Force Base, Oklahoma, while Edwards Air Force Base, California will lead testing and evaluation. The B-21 is expected to operate out of bases currently servicing heavy bombers, such as Dyess Air Force Base, Texas, Ellsworth Air Force Base, South Dakota, and Whiteman Air Force Base, Missouri. On 27 March 2019, Ellsworth Air Force Base was selected as the Air Force Base to host the first operational B-21 Raider bomber unit and the first formal training unit
