B90 nuclear bomb
Encyclopedia
The B90 was an American thermonuclear bomb designed in the mid to late 1980s and cancelled prior to introduction into military service.
The B90 design was intended for use as a naval aircraft weapon, for use as a nuclear depth bomb and as a land attack strike bomb. It was intended to replace the B57 nuclear bomb
used by the Navy. The B90 bomb design entered Phase 3 development engineering and was assigned its numerical designation in June 1988.
The B90 was 13.3 inches in diameter and 118 inches long, and weighed 780 pounds. The B90 had a design yield of 200 kilotons.
The B90 was cancelled in September 1991 along with the W89
and W91
nuclear warheads and AGM-131 SRAM II
and SRAM-T missile models. No B90 production models were built, though test units may have been; US nuclear weapon testing continued until 1992.
