Blue Peacock was designed after the free-falling Blue Danube and weighed 7.2 long tons (7,300 kg). A total of two firing units were built: the casing and the warhead. Due to its large steel casing, it had to be tested outdoors in a flooded gravel pit near Sevenoaks in Kent. [3]
Hiroshima was the primary target of the first atomic bombing mission on 6 August, with Kokura and Nagasaki as alternative targets. The 393rd Bombardment Squadron B-29 Enola Gay, named after Tibbets's mother and piloted by Tibbets, took off from North Field, Tinian, about six hours' flight time from Japan, [126] at 02:45 local time.

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.
1968 – January 28 – An aircraft accident occurs when an American B-52 bomber armed with a Mark 28 nuclear bomb bound for Thule Air Base, Greenland, has an in-flight fire and is forced to make a crash landing in North Star Bay, resulting in the detonation of the bomb's conventional explosives and the release of radioactive contamination over ...
A bomb was mistakenly dropped by a U.S. Air Force Boeing B-47E-LM Stratojet near Savannah, Georgia when a man in the bomb bay area grabbed the emergency release pin by accident. Similar to the 1957 incident, safety precautions meant that the plutonium was not mounted to the bomb but rather stored elsewhere on the plane at the time.
At the first major theoretical conference on the development of an atomic bomb hosted by J. Robert Oppenheimer at the University of California, Berkeley in the summer of 1942, Teller directed the majority of the discussion towards this idea of a "Super" bomb. It was thought at the time that a fission weapon would be quite simple to develop and ...
[8] The piece used sound and light to startle the viewer. [9] Months (measured in seconds) are represented by a sound. [10] When a nuclear explosion occurs, a musical sound plays. [11] Different countries have different tones, which sometimes results in a polyphonic composition, [11] overwhelming the viewer.
The weapon was delayed until August 1963 due to issues with the timer. These included premature firing of the timer and issues with bearing materials. An interim Mk 54 Mod 0 weapon (now called the B54-0) was put into production in April 1963. Drop tests for this weapon were conducted at velocities up to 31 feet per second (9.4 m/s) vertical and ...
