The atomic bomb explosion generated a windstorm several kilometers wide that carried ash, dust, and debris over the mountain ranges surrounding Nagasaki. Approximately 20 minutes after the bombing, a black rain with the consistency of mud or oil came down carrying radioactive material for one to two hours before turning clear. [227]
When the Mk 20 bomb cluster is released from the aircraft, the arming wires (primary and/or optional arming) are pulled sufficiently to arm the Mk 339 fuze (and recently the FMU-140 fuze) and release the fins. The positive armed fin release arming wire frees the fin release band, and the movable fins snap open by spring-force.
The GBU-57A/B MOP (Massive Ordnance Penetrator) is a precision-guided, 30,000-pound (14,000 kg) "bunker buster" bomb used by the United States Air Force. [2] The GBU-57 (Guided Bomb Unit-57) is substantially larger than the deepest-penetrating bunker busters previously available, the 5,000-pound (2,300 kg) GBU-28 and GBU-37.
The GBU-39/B Small Diameter Bomb (SDB) is a 250-pound (110 kg) precision-guided glide bomb that is intended to allow aircraft to carry a greater number of smaller, more accurate bombs. Most US Air Force aircraft will be able to carry (using the BRU-61/A rack [ 16 ] ) a pack of four SDBs in place of a single 2,000-pound (910 kg) Mark 84 bomb .
A typical mission dropped 168 tons of ordnance, dropping the bombs over an area 1.5 by 0.5 miles (2.41 by 0.80 km) with an explosive force equivalent to 10 to 17 MOABs. [11] [12] [13] MOAB was first tested with the explosive tritonal on 11 March 2003, on Range 70 located at Eglin Air Force Base in Florida. It was tested again on 21 November ...
The remaining bomb casings are located at the Russian Atomic Weapon Museum in Sarov and the Museum of Nuclear Weapons, All-Russian Scientific Research Institute Of Technical Physics, in Snezhinsk. Tsar Bomba was a modification of an earlier project, RN202, which used a ballistic case of the same size but a very different internal mechanism. [16]
The US was 3-0 up inside the opening 15 minutes in its match against Japan, and the game was being played at a frantic pace. In a frenetic Women’s World Cup final, Carli Lloyd pounced on a loose ...
