Project Iceworm was a top secret United States Army program of the Cold War, which aimed to build a network of mobile nuclear missile launch sites under the Greenland ice sheet. The goal was to install a vast network of nuclear missile launch sites that could survive a first strike. This was according to documents declassified in 1996. [1]
On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki, respectively.The bombings killed between 150,000 and 246,000 people, most of whom were civilians, and they remain the only use of nuclear weapons in an armed conflict.
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 limiting value of the albedo for high-Z materials is reached when the thickness is 5–10 g/cm 2, or 0.5–1.0 free paths. Thus, a hohlraum made of uranium much thicker than a free path of uranium would be needlessly heavy and costly. At the same time, the angular anisotropy increases as the atomic number of the scatterer material is reduced.
The film is divided into two main segments. The first section of the film is a dramatization of a sneak attack by Soviet Union nuclear weapons against the United States.The premise of the attack is based on Soviet nuclear submarines approaching the United States West Coast and launching a barrage of missiles at ICBM silos and B-52 bomber bases, and other Soviet forces manage to destroy a ...
Two U.S. researchers say they have identified the probable deployment site in Russia of the 9M370 Burevestnik, a new nuclear-powered, nuclear-armed cruise missile touted by President Vladimir ...
The name Fat Man refers to the early design of the bomb because it had a wide, round shape. Fat Man was an implosion-type nuclear weapon with a solid plutonium core. The first of that type to be detonated was the Gadget in the Trinity nuclear test less than a month earlier on 16 July at the Alamogordo Bombing and Gunnery Range in New Mexico.
