B-1 Lancer

The Rockwell B-1 Lancer is a supersonic variable-sweep wing, heavy bomber used by the United States Air Force. It has a payload capacity of 75,000 pounds, making it the heaviest payload of any U.S. bomber. The B-1 was first envisioned in the 1960s as a combination of the speed of the B-58 Hustler and the range and payload of the B-52, but its initial development was canceled in 1977 due to high costs and the introduction of the AGM-86 cruise missile. The program was restarted in 1981 and the B-1B variant entered service in 1986, initially as a nuclear bomber but later converted for conventional bombing. The B-1B has supported U.S. and NATO military forces in several conflicts and is planned to be replaced by the Northrop Grumman B-21 Raider after 2025.learn more on wikipedia
