Operation Buster–Jangle was a series of seven (six atmospheric, one cratering)
nuclear weapons tests conducted by the United States in late 1951 at the
Nevada Test Site.
Buster-Jangle was the first joint test program between the
DOD (Operation
Buster) and
Los Alamos National Laboratories (Operation
Jangle). As part of Operation
Buster, 6,500
troops were involved in the
Operation Desert Rock I, II, and III exercises in conjunction with the tests. The last two tests, Operation
Jangle, evaluated the cratering effects of low-yield nuclear devices. This series preceded
Operation Tumbler-Snapper and followed
Operation Greenhouse.
