Underwater explosions are categorized by the depth of the explosion. Shallow underwater explosions are those where a crater formed at the water's surface is large in comparison with the depth of the explosion. Deep underwater explosions are those where the crater is small in comparison with the depth of the explosion, [2] or nonexistent. The ...
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.
All mission-essential equipment on board military surface ships and submarines must be qualified for underwater shock loads caused by depth charges, naval mines, missiles, and torpedoes. An underwater explosion nearby a ship or submarine can be devastating to the combat readiness of the vessel. Damage may occur in the form of dished hull ...
Underwater explosions using dry ice and liquid nitrogen are captured in high definition slow motion by The Backyard Scientist.
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 ...
An explosion of a naval mine A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines . Similar to anti-personnel and other land mines , and unlike purpose launched naval depth charges , they are deposited and left to wait until, depending on their fuzing , they are triggered by the ...
This is to some degree compensated by a heavy payload, in some mines exceeding half a metric ton, but since the effect of an underwater explosion decreases with a factor of the distance cubed, an increase in payload of a depth charge from 100 to 200 kg would not result in more than a few meters in killing radius.
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 ...
