Rockwell B-1B Lancer The highlight of opening day at Oshkosh was the arrival of the B-1B Lancer, a supersonic long range, heavy bomber nicknamed “the Bone”. It’s one of the three strategic bombers in the US fleet along with the B-2 Spirit stealth bomber and the B-52 Stratofortress. The B1-B can carry the largest conventional payload of both guided and unguided weapons of all America’s long-range bombers and can deliver those weapons against any adversary, anywhere in the world, at any time.
