An underwater explosion (also known as an UNDEX) is a chemical or nuclear explosion that occurs under the surface of a body of water. While useful in anti-ship and submarine warfare, underwater bombs are not as effective against coastal facilities.
An explosion is a type of spontaneous chemical reaction that, once initiated, is driven by both a large exothermic change (great release of heat) and a large positive entropy change (great quantities of gases are released) in going from reactants to products, thereby constituting a thermodynamically favorable process in addition to one that ...
The damage that an underwater explosion inflicts on a submarine comes from a primary and a secondary shock wave. The primary shock wave is the initial shock wave of the depth charge, and will cause damage to personnel and equipment inside the submarine if detonated close enough.
Underwater explosions using dry ice and liquid nitrogen are captured in high definition slow motion by The Backyard Scientist.
Shock factor is a commonly used figure of merit for estimating the amount of shock experienced by a naval target from an underwater explosion as a function of explosive charge weight, slant range, and depression angle (between vessel and charge).
Underwater blast Blast fishing , fish bombing , dynamite fishing or grenade fishing is a destructive fishing practice using explosives to stun or kill schools of fish for easy collection. This often illegal practice is extremely destructive to the surrounding ecosystem , as the explosion often destroys the underlying habitat (such as coral ...
During the Attack of Pearl Harbor, the USS Arizona was struck with an armor-piercing bomb which penetrated the upper deck and stopped inside the forward magazine. The bomb triggered an explosion which was powerful enough to cut the Arizona in half and is considered a sympathetic detonation as there was an apparent delay between the detonation of the bomb and the contents of the forward magazine.
Underwater dump sites off the Los Angeles coast contain World War II-era munitions including anti-submarine weapons and smoke devices, marine researchers announced Friday. A survey of the known ...
