The W56 (originally called the Mark 56) was an American thermonuclear warhead produced starting in 1963 which saw service until 1993, on the Minuteman I and II ICBMs.
The warhead had a yield of and a demonstrated yield-to-weight ratio of , very close to the predicted achievable in the highest yield to weight weapon ever built, the B41. Unlike the B41, which was never tested at its full yield, the W56 demonstrated its efficiency in the XW-56-X2 Bluestone shot of Operation Dominic in 1962.
