The B61 nuclear bomb is the primary thermonuclear gravity bomb in the United States Enduring Stockpile following the end of the Cold War. It is a low-to-intermediate yield strategic and tactical nuclear weapon featuring a two-stage radiation implosion design.
W81 warhead and SM-2 missile. The W81 was a planned American warhead to be mounted on the SM-2 surface-to-air missile used by the United States Navy.The W81 was believed to be derived from the B61 nuclear bomb which forms the backbone of the current US nuclear gravity bomb arsenal and from which the W80 cruise missile warhead is derived.
The overall B61 bomb is 13.3 inches (340 mm) in diameter and 141 inches (3,600 mm) long, and weighs approximately 700 pounds (320 kg) across most mods. The nuclear device within the outer B61 envelope is probably the same overall dimensions and weight as the W80 warhead, which is 11.8 inches (300 mm) in diameter, 31.4 inches (800 mm) long and ...
