The Operation Ivy test series was the first to involve a hydrogen bomb rather than an atomic bomb, further to the order of President Harry S. Truman made on January 31, 1950, that the US should continue research into all forms of nuclear weapons.
The blast created a crater 1.9 km (6,230 ft) in diameter and 50 m (164 ft) deep where Elugelab had once been; [24] the blast and water waves from the explosion (some waves up to 6 m (20 ft) high) stripped the test islands clean of vegetation, as observed by a helicopter survey within 60 minutes after the test, by which time the mushroom cloud ...

The operation consisted of 29 explosions, of which only two did not produce any nuclear yield.Twenty-one laboratories and government agencies were involved. While most Operation Plumbbob tests contributed to the development of warheads for intercontinental and intermediate range missiles, they also tested air defense and anti-submarine warheads with smaller yields.
The Nevada National Security Sites (N2S2 [1] or NNSS), popularized as the Nevada Test Site (NTS) until 2010, [2] is a reservation of the United States Department of Energy located in the southeastern portion of Nye County, Nevada, about 65 mi (105 km) northwest of the city of Las Vegas.

[55] [56] In January 2016, North Korea claimed to have successfully tested a hydrogen bomb, [57] although only a magnitude 5.1 seismic event was detected at the time of the test, [58] a similar magnitude to the 2013 test of a 6–9 kt (25–38 TJ) atomic bomb. These seismic recordings cast doubt upon North Korea's claim that a hydrogen bomb was ...
