==Design== Declassified British documents describe the Mod 1 and Mod 2 versions of the weapon as having three yields between , while the Mod 3 enhanced radiation version was estimated to have a yield of The Mod 1 reportedly had more yield options than the Mod 2 warheads. The Mod 3 was reportedly 40% fission and 60% fusion, with two yield options. The weapon weighed , and was long and in diameter.
