In July 1950, soon after the outbreak of the Korean War, the Joint Chiefs of Staff resolved to send ten Silverplate (nuclear-capable) Boeing B-29 Superfortress bombers to Guam as a deterrent to a People's Republic of China (PRC) attack on Taiwan, (Republic of China), and for possible future use in Korea, [4] each loaded with a Mark 4 nuclear bomb without the fissile pit.
Before the tank was filled, the system unexpectedly went critical. An estimated 3-4×10 16 fissions occurred and the temperature of the metal may have risen to 200º Celsius. Several personnel were exposed to non-lethal amounts of radiation, and the material was re-used for experiments within days. [4] August 21, 1945
[3] [4] The damaged B-47 remained airborne, plummeting from 38,000 feet (12,000 m) until the pilot, Col. Howard Richardson, regained control at 20,000 feet (6,100 m). [5] [6] The crew requested permission to jettison the bomb, in order to reduce weight and prevent the weapon from exploding during an emergency landing. Permission was granted ...
The Mark 4 nuclear bomb was an American implosion-type nuclear bomb based on the earlier Mark 3 Fat Man design, used in the Trinity test and the bombing of Nagasaki.With the Mark 3 needing each individual component to be hand-assembled by only highly trained technicians under closely controlled conditions, the purpose of the Mark 4 was to produce an atomic weapon as a practical piece of ordnance.
