Bombs typically rupture within 30 seconds to half an hour, dependent largely on the temperature of the air outside the bottle. [1] A dry ice bomb may develop frost on its exterior prior to explosion. [1] After explosion, it appears to have shattered, with the overall shape of the device intact. [1]
In mid-September 1954, nuclear bombing tests were performed at the Totskoye proving ground during the training exercise Snezhok (Russian: Снежок, Snowball or Light Snow) with some 45,000 people, all Soviet soldiers and officers, [3] who explored the explosion site of a bomb twice as powerful as the one dropped on Nagasaki nine years earlier.
Car bomb: A vehicle is packed with explosives and detonated. Cluster bomb: Over a hundred nations outlaw them now. The first one was Butterfly Bomb: Germany: General-purpose bomb: Glide bomb: Guided bomb: Improvised explosive device: Land mine: Explodes when pressure is applied to the bomb. Outlawed in 164 nations. 1832 Ming Dynasty: Laser ...
The 1951 Shot Uncle of Operation Buster-Jangle, had a yield about a tenth of the 13 to 16 Kt Hiroshima bomb, 1.2 Kt, [193] and was detonated 5.2 m (17 ft) beneath ground level. [194] No thermal flash of heat energy was emitted to the surroundings in this shallow buried test. [193] The explosion resulted in a cloud that rose to 3.5 km (11,500 ft ...
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.

Since the E1 component of nuclear EMP depends on the prompt gamma-ray output, which was only 0.1% of yield in Starfish Prime but can be 0.5% of yield in low-yield pure nuclear fission weapons, a 10 kt (42 TJ) bomb can easily be 5 * 8%= 40% as powerful as the 1.44 Mt (6.0 PJ) Starfish Prime at producing EMP.
The tamper had a radius of 17.5 centimetres (6.9 in) and a thickness of 11.3 centimetres (4.4 in), for a mass of 317 kilograms (699 lb). This was about 3.5 times the mass of the fissile material used. Tungsten carbide has a high density and a low neutron absorbency cross section.
[1] [3] The two wings of the PFM-1 allow it to glide after being released in the air, then spin, stabilizing it and slowing its descent, similar to maple seeds. [4] [1] The thick wing contains the liquid explosive. [4] The two wings together are 120 mm (4.7 in) long. [5] The plastic body can be produced in a variety of colours for best camouflage.
