  2. Thermonuclear weapon - Wikipedia

    en.wikipedia.org/wiki/Thermonuclear_weapon

    [55] [56] In January 2016, North Korea claimed to have successfully tested a hydrogen bomb, [57] although only a magnitude 5.1 seismic event was detected at the time of the test, [58] a similar magnitude to the 2013 test of a 6–9 kt (25–38 TJ) atomic bomb. These seismic recordings cast doubt upon North Korea's claim that a hydrogen bomb was ...

  3. Nuclear shaped charge - Wikipedia

    en.wikipedia.org/wiki/Nuclear_shaped_charge

    The nuclear shaped charge concept was also studied extensively in the 1980s as part of Project Prometheus, along with bomb-pumped lasers. Using a combination of explosive wave-shaping and "gun-barrel" design, up to 5% of a small nuclear bomb could reportedly be converted into kinetic energy driving a beam of particles with a beam angle of 0.001 ...

  4. Casaba-Howitzer - Wikipedia

    en.wikipedia.org/wiki/Casaba-Howitzer

    A conventional hydrogen bomb includes two stages; the primary is an atomic bomb normally based on plutonium, while the secondary is a mixture of fusion fuel and various boosters. The primary releases an intense burst of X-rays that heat channel filler materials (believed to be similar to styrofoam ) surrounding the secondary.

  5. Fusion rocket - Wikipedia

    en.wikipedia.org/wiki/Fusion_rocket

    The simplest way of building a fusion rocket is to use hydrogen bombs as proposed in Project Orion, but such a spacecraft would be massive and the Partial Nuclear Test Ban Treaty prohibits the use of such bombs. For that reason bomb-based rockets would likely be limited to operating only in space.

    This crash project was developed partially with information obtained via the atomic spies at the United States' Manhattan Project during and after World War II. The Soviet Union was the second nation to have developed and tested a nuclear weapon. It tested its first megaton-range hydrogen bomb ("RDS-37") in 1955.

    The hydrogen bomb, which carried the force of 50 million tons of conventional explosives, was detonated in a test in October 1961, 4,000 meters over the remote Novaya Zemlya archipelago above the ...

  9. High-altitude nuclear explosion - Wikipedia

    en.wikipedia.org/wiki/High-altitude_nuclear...

    The visual effects of a high-altitude or space-based explosion may last longer than atmospheric tests, sometimes in excess of 30 minutes. Heat from the Bluegill Triple Prime shot, at an altitude of 50 kilometers (31 miles), was felt by personnel on the ground at Johnston Atoll , and this test caused retina burns to two personnel at ground zero ...
