A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs, a more compact size, a lower mass, or a combination of these benefits.
The Tsar Bomba is the single most physically powerful device ever deployed on Earth, the most powerful nuclear bomb tested and the largest human-made explosion in history. [65] For comparison, the largest weapon ever produced by the US, the now-decommissioned B41, had a predicted maximum yield of 25 Mt (100 PJ).
The initial explosion catapulted the 740-ton silo door away from the silo and ejected the second stage and warhead. Once clear of the silo, the second stage exploded. The W53 thermonuclear warhead landed about 100 feet (30 m) from the launch complex's entry gate. Its safety features prevented any loss of radioactive material or nuclear detonation.
The Fat Man weapon, containing a core of about 5 kg (11 lb) of plutonium, was dropped over the city's industrial valley. It exploded 47 seconds later at 11:02 Japanese Time [127] at 503 ± 10 m (1,650 ± 33 ft), above a tennis court, [207] halfway between the Mitsubishi Steel and Arms Works in the south and the Nagasaki Arsenal in the north.
A Mark 6 nuclear bomb, similar to the one dropped in the incident, at the National Museum of the United States Air Force.. On March 11, 1958, a U.S. Air Force Boeing B-47E-LM Stratojet from Hunter Air Force Base operated by the 375th Bombardment Squadron of the 308th Bombardment Wing near Savannah, Georgia, took off at approximately 4:34 PM and was scheduled to fly to the United Kingdom and ...
The first thing you'd see if a nuclear bomb exploded nearby is a flood of light so bright, you may think the sun blew up -- but don't try to drive away. If a nuclear bomb explodes nearby, here's ...
As of 2013 the Pentagon saw the B83 nuclear bomb as a "relic of the Cold War," believing that deploying a megaton-yield gravity bomb, the highest level nuclear weapon left in the U.S. inventory, to Europe was "inconceivable" at this point. It can also only be carried by the B-2 bomber, and integrating it onto additional aircraft would be costly.
The Mark 39 Mod 2 was initially pursued with the goal of providing the Mod 1 with a low-level release capability, where the weapon would "detonate some time after the weapon struck the target and came to rest". Work was initially done on creating a new parachute system, and the weapon system was initially called to Mark 39 Mod 1 Big Tail.
