W25

The W25 was a small nuclear warhead developed by the United States Air Force and Los Alamos Scientific Laboratory for air-defense use. It was a fission device with a nominal yield of 1.7 kT. Development of the weapon began in 1954 at the behest of Douglas Aircraft for use against enemy bombers.The W25 was used for the MB-1 "Ding Dong", an unguided air-to-air rocket used by the F-89 Scorpion, F-101B, and F-106 interceptor aircraft. The MB-1 entered service in 1957, and was eventually redesignated the AIR-2 Genie. Limited numbers were still used for Air National Guard F-106 aircraft until December 1984.
