Operation Buster-Jangle
1951 - Nevada Test Site
Buster-Jangle was held at the Nevada Proving Ground (later NTS) and had a number of objectives. The Buster series was primarily a weapon development effort. A number of pit configurations were fired in a Mk-4 high explosive assembly to collect data for weapons design. The DOD also particpated in one of the Buster tests conducting the Desert Rock I exercise during the Dog shot. The Jangle series evaluated the usefulness of atomic weapons in cratering using ground-level and sub-surface bursts. The Desert Rock II and III troop exercises were held in conjunction with these tests. The purpose of the Desert Rock exercises was to gain experience in operations conducted in a nuclear combat environment.
