Rockwell B-1B Lancer

The Rockwell B-1B is a derivative of the B-1 bomber, which was a planned 1980 replacement for the B-52. It was to be the third and most flexible of the Triad defence system, the other two being land and submarine based ballistic missiles. The first B-1 flew on December 23rd, 1974 and was assembled at Plant 42 in Palmdale California. The fourth B-1 flew on February 14th, 1979, and was the only complete plane to be fitted with full offensive and defensive weapons. In 1977 then President Carter cancelled the B-1 program in favour of the cruise missile development program.
