On August 1, 1958, Redstone rocket launched nuclear test Teak that detonated at an altitude of 77.8 km (48.3 mi). On August 12, 1958, Redstone #CC51 launched nuclear test Orange to a detonation altitude of 43 km (27 mi). Both were part of Operation Hardtack I and had a yield of 3.75 Mt
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 ).
Operation Dominic was a series of 31 nuclear test explosions ("shots") with a 38.1 Mt (159 PJ) total yield conducted in 1962 by the United States in the Pacific. [1] This test series was scheduled quickly, in order to respond in kind to the Soviet resumption of testing after the tacit 1958–1961 test moratorium.
