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.
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 Mod 2 nomenclature indicates the hardened version of the weapon designed to survive laydown delivery; earlier Mod 0 and Mod 1 weapons could not survive the forces involved. [13] The Y1 nomenclature indicates a W28 warhead with a yield of 1.1 megatonnes of TNT (4,600 TJ).
The last two effects travel close together, but the air blast goes much further, and it causes the most damage in a nuclear explosion by tumbling vehicles, toppling weak buildings, and throwing ...
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 ...
Nuclear bomb burned after B-47 aircraft accident B-47 aircraft crashed during take-off after a wheel exploded; one Mark 15 Mod 0 nuclear bomb burned in the resulting fire. [34] The aircraft was carrying the unarmed weapon in a ferry configuration in the bomb bay, and the nuclear capsule in the crew compartment.
Death is highly likely and radiation poisoning is almost certain if one is caught in the open with no terrain or building masking effects within a radius of 0–3 kilometres (0.0–1.9 mi) from a 1 megaton airburst, and the 50% chance of death from the blast extends out to ~8 kilometres (5.0 mi) from the same 1 megaton atmospheric explosion.
A nuclear close call is an incident that might have led to at least one unintended nuclear detonation or explosion, but did not. These incidents typically involve a perceived imminent threat to a nuclear-armed country which could lead to retaliatory strikes against the perceived aggressor.
