Sedan was a thermonuclear device with a fission yield less than 30% and a fusion yield about 70%. [3] [4] According to Carey Sublette, the design of the Sedan device was similar to that used in the Bluestone and Swanee tests of Operation Dominic conducted days and months prior to Sedan respectively, and was therefore not unlike the W56 high yield Minuteman I missile warhead.

The bomb later gained the name "Dirty Harry" because of the amount of off-site fallout generated by the bomb. [ 37 ] A 1962 United States Atomic Energy Commission report found that "children living in St. George, Utah may have received doses to the thyroid of radioiodine as high as 120 to 440 rads " (1.2 to 4.4 Gy).

Trinity, part of Project Manhattan, was the first ever nuclear explosion. The nuclear weapons tests of the United States were performed from 1945 to 1992 as part of the nuclear arms race. The United States conducted around 1,054 nuclear tests by official count, including 216 atmospheric, underwater, and space tests.
The MET was the first bomb core to include uranium-233 (a rarely used fissile isotope that is the product of thorium-232 neutron absorption), along with plutonium; this was based on the plutonium/U-235 pit from the TX-7E, a prototype Mark 7 nuclear bomb design used in the 1951 Operation Buster-Jangle Easy test.
On this day in 1957, the first underground nuclear test was carried out at the Nevada Test Site, a 1,375 square-mile research center located 65 miles away from Las Vegas.The 1,7 kiloton nuclear ...
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 test area, also known as Area 13, was a 10 miles (16 km) by 16 miles (26 km) block of land abutting the northeast boundary of the Nevada National Security Site. [3] Project 57 was a combination safety test. The high explosives of a nuclear weapon were detonated asymmetrically to simulate an accidental detonation.
