Experiences of trench warfare on the Western front in 1914–1916 indicated that British artillery was unable to reliably destroy barbed-wire barricades, which required shells to explode instantaneously on contact with the wire or ground surface: British high-explosive shells would penetrate the ground before exploding, rendering them useless ...
The German Stachelbombe (nose-spike bomb) or stabo of WWII was a standard bomb, from 50 kg to 500 kg, modified for use from low altitude. [5] To avoid the risk of ricochet from the ground, a nose spike was fitted to penetrate first and anchor the bomb against bouncing — without this, there was a risk of the dropping aircraft not only missing ...
The main design consideration is that the bomb that the fuze is intended to actuate is stationary, and the target itself is moving in making contact. Naval mines Relevant design factors in naval mine fuzes are that the mine may be static or moving downward through the water, and the target is typically moving on or below the water surface ...
It recently took a team of 30 Marines, a few hours, and thousands of feet of detonation cord to set up one of these awe-inspiring infernos.
Today's punks (wood splints covered with ground plant pith or dung and then saturated with nitrate) used for lighting consumer fireworks are a type of slow match. A black match is a type of fuse consisting of cotton string coated with a dried slurry of black powder and glue. This acts as a simple pass-fire, and was used to fire ancient cannons.
The GBU-57A/B Massive Ordnance Penetrator (MOP) 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 exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much more ...
The Lexington Police Department’s bomb squad was called to the scene and safely removed the product from the building. No injuries were reported, according to Johnson.
