Operation Buster/Jangle, conducted October and November 1951 at the Nevada Proving Ground, was comprised of five shots under Buster (Able, Baker, Charlie, Dog, Easy) and two under Jangle (Sugar, Uncle). The Los Alamos Scientific Laboratory sponsored all of the Buster events, while the Department of Defense (DoD) sponsored the first Jangle shot, and DoD and the Laboratory jointly sponsored the second event.

The two Jangle shots provided the first experimental data on the military effects of surface and underground nuclear detonations, determining response of structures to nuclear bursts, gamma radiation versus time and distance, and residual contamination from surface and underground bursts.
