Source-derived summary

The Northrop Grumman B-21 Raider is an American nuclear-capable subsonic stealth strategic bomber in development for the United States Air Force (USAF) by Northrop Grumman. Part of the Long Range Strike Bomber (LRS-B) program, it is to be an intercontinental strategic bomber that can deliver conventional and thermonuclear weapons. Named "Raider" after the Doolittle Raiders of World War II, the B-21 is meant to complement the Rockwell B-1 Lancer and Northrop B-2 Spirit, replace them by 2040, and possibly replace the 1950s Boeing B-52 Stratofortress after that.
