The setting sun silhouettes a B-1B Lancer, Dec. 12, at an undisclosed air base in Southwest Asia. Carrying the largest payload of both guided and unguided weapons in the Air Force inventory, the multi-mission B-1 is the backbone of America's long-range bomber force. It can rapidly deliver massive quantities of precision and non-precision weapons against any adversary, anywhere in the Central Command area of responsibility. (U.S. Air Force photo by Tech. Sgt.
