The Northrop Grumman B-21 Raider is a heavy bomber 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 conventional or thermonuclear weapons.

The bomber is expected to enter combat service by 2025 and replace the B-1 Lancer and B-52 Stratofortress in U.S. service.

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). 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. 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. 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.Initial operating capability is expected to be reached by 2030.

In March 2016, the USAF announced seven tier-one suppliers for the program, including 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.
