The military makes a big deal out of when a rifle goes missing, not to mention when a nuke disappears. In spite of the fact the program is designed to be "zero defect," here are 7 examples of doomsday devices wandering off (including a few where they never came back):


1. 1956: B-47 disappears with two nuclear capsules

The USS Scorpion, a nuclear-powered attack submarine, was declared presumed lost on June 5, 1968. The loss was especially troubling for the Navy since the boat had been following a Russian research group just before its disappearance. At the time it was lost, the Scorpion was carrying two Mark 45 antisubmarine torpedoes (ASTOR). The wreckage would not be found until October 1968. The USS Scorpion is still on the floor of the Atlantic under 3,000 meters of water and the cause of the sinking remains unknown. The torpedo room appears to be intact with the two nuclear torpedoes in position, but the Navy can't tell for sure. Recovery of the torpedoes would be extremely challenging, so the Navy monitors radiation levels in the area instead. So far, there has been no signs of leakage from torpedoes or the reactor.
