Operation Hardtack II

Operation Hardtack II was a series of 37 nuclear tests conducted by the United States in 1958 at the Nevada Test Site.

With test moratoriums on the horizon, American weapons labs rushed out many new designs. After the conclusion of Hardtack II, the United States announced a unilateral testing moratorium, which the Soviet Union joined until September, 1961.^[1] In September 1961, the Soviet Union resumed nuclear testing, and the United States followed suit with Operation Nougat.
