At Emu Field, a flat clay-and-sandstone expanse 480 kilometers northwest of Woomera, South Australia, Britain detonated its second atomic weapon -- a Blue Danube bomb mounted on a steel tower, 300 meters above the ground. The yield was 10 kilotons, slightly larger than expected. Twelve days later, a second device followed, producing 7 kilotons when planners had anticipated only 2 to 3. Together, these two blasts constituted Operation Totem, a test series whose purpose was technical and specific: to determine how much plutonium-240 could be tolerated in a weapon before it risked a fizzle.

Photo credit Unknown author, Public domain. The total cost of Operation Totem was 828,000 pounds, split between Britain and Australia. When the tests concluded, the Emu Field site was abandoned. Personnel flew out on RAAF aircraft. Penney returned to England. The site's remoteness, which had recommended it for secrecy, now...
