The Joe-1 atomic bomb test by the Soviet Union that took place in August 1949 came earlier than expected by Americans, and over the next several months there was an intense debate within the U.S. government, military, and scientific communities regarding whether to proceed with development of the far more powerful Super.

Beginning in 1951, Cowan and Reines, both then scientists at Los Alamos, New Mexico, initially thought that neutrino bursts from the atomic weapons tests that were then occurring could provide the required flux. [8] For a neutrino source, they proposed using an atomic bomb. Permission for this was obtained from the laboratory director, Norris ...
With miniaturization, nuclear bombs can be delivered by both strategic bombers and tactical fighter-bombers. This method is the primary means of nuclear weapons delivery; the majority of US nuclear warheads, for example, are free-fall gravity bombs, namely the B61, which is being improved upon to this day.

The Scandalous Science Behind Nuclear Regulation. James Broughel. May 15, 2024 at 7:30 AM ... as fears of radioactive fallout from above-ground nuclear weapons testing dominated public discourse.
In 1942, there was speculation among the scientists developing the first nuclear weapons in the Manhattan Project that a sufficiently large nuclear explosion might ignite the Earth's atmosphere: heat from the explosion might fuse pairs of atmospheric nitrogen atoms, forming carbon and oxygen while releasing further energy which would sustain ...
The first nuclear explosive devices provided the basic building blocks of future weapons. Pictured is the Gadget device being prepared for the Trinity nuclear test.. Nuclear Weapons Design are physical, chemical, and engineering arrangements that cause the physics package [1] of a nuclear weapon to detonate.
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.
Twenty-eight nuclear blasts were detonated between 1961 and 1973. One of the first U.S. proposals for peaceful nuclear explosions that came close to being carried out was Project Chariot, which would have used several hydrogen bombs to create an artificial harbor at Cape Thompson, Alaska. It was never carried out due to concerns for the native ...
