Overview
The B-1 Lancer, nicknamed ‘The Bone’ (B-One), is a supersonic variable-sweep wing strategic bomber that has evolved from its original nuclear penetration role into the USAF’s primary conventional heavy bomber, dropping more ordnance in Iraq and Afghanistan than any other platform.
Design & Development
The B-1B features variable-sweep wings (15° to 67.5°), blended wing-body design for reduced radar cross-section, and three internal weapons bays capable of carrying 75,000 lb of ordnance. While the original B-1A prototype could reach Mach 2.2, the production B-1B was optimized for low-altitude penetration at Mach 0.92, with high-altitude dash capability of Mach 1.25.
Operational History
100 B-1Bs were built and entered service in 1986. Since 2001, the B-1B has been the workhorse of US strategic bombing campaigns. A single B-1B can carry the equivalent of an entire WWII bomber squadron’s payload. The fleet is being retired as the B-21 Raider enters service.
