The B-1 Lancer bomber is a "highly versatile, multi-mission weapon system," according to the Air Force, and it is "capable of tracking, targeting and engaging moving vehicles as well as self-targeting and terrain-following mode."
The aircraft carries the largest conventional payload of both guided and unguided weapons in the Air Force inventory" and is considered "the backbone of America's long-range bomber force," according to its description on the USAF website.
While 100 were originally built, fewer than 60 remain in service at Dyess Air Force Base in Texas and at Ellsworth, the AP reported.
