Manufactured by Rockwell, the B-1 Lancer bomber, affectionately known as the ‘Bone’ is a four engine supersonic aircraft with variable swept wings. The B-1 was originally thought to be a replacement for the B-52 Stratofortress. It entered service in 1986 as a nuclear bomber but has been widely used in a conventional role.
