Red Snow was a British thermonuclear weapon,[1] based on the US W28 (then called Mark 28) design used in the B28 thermonuclear bomb and AGM-28 Hound Dog missile.[2] The US W28 had yields of 70, 350, 1,100 and 1,450 kilotonnes of TNT (0.29, 1.46, 4.60 and 6.07 PJ)[3] and while Red Snow yields are still classified, declassified British documents indicate the existence of "kiloton Red Snow" and "megaton Red Snow" variants of the weapon, suggesting similar yield options, while other sources have suggested a yield of approximately 1 megatonne of TNT (4.2 PJ).[4][5]

Red Snow is the British version of the U.S. Mk.28, which has been tested by the American Authorities. It follows that all current British nuclear weapons are based on tested designs.
