Rockwell's B-1 Lancer, also known as "Bone" (B-One), is basically a supersonic variable-sweep wing, heavy bomber used by the United States Air Force (USAF), and one of three strategic bombers in the USAF fleet as of 2017. The B-1B began deliveries in 1986 and formally entered service with Strategic Air Command (SAC) as a nuclear bomber in 1986. By 1988, all 100 aircraft had been delivered. The aircraft has a maximum speed of Mach 1.25 at higher altitudes. The B-1B is expected to continue to serve into the 2030s, with the Northrop Grumman B-21 Raider to begin replacing the B-1B after 2025. The B-1s currently in inventory will reach the end of their service lives by 2045. Click here to view the first image in today's viral picture gallery.
