A depth charge is an anti-submarine warfare ... Very large depth charges, including nuclear weapons, may be detonated at sufficient depth to create multiple damaging ...
Perhaps the simplest of the anti-submarine weapons, the depth charge, is a large canister filled with explosives and set to explode at a predetermined depth. The concussive effects of the explosion could damage a submarine from a distance, though a depth charge explosion had to be very close to break the submarine's hull.
The Mark VII depth charge was the primary British anti-submarine weapon until 1944 when the anti-submarine projectile launchers the Hedgehog spigot mortar and Squid three-barrelled mortar introduced in 1943 and 1944 proved more effective. [1]
Starting with WW1 vintage 300-pound (140 kg) depth charges, a 600-pound (270 kg) version was developed. Torpex explosive, which is a 50% more powerful explosive than TNT, was introduced in 1943. Y-guns and K-guns were used to throw depth charges to the side of the escort vessel, augmenting the charges rolled off the stern and letting the escort ...
During the action, a few depth charges became loose aboard Christabel, and at great personal risk Ensign Daniel Augustus Joseph Sullivan secured them, earning him the Medal of Honor. [10] On June 6 U-151 attacked the British ocean liner SS Dwinsk about 400 miles east of the Bermudas. Twenty-two crewmen were lost, but the rest survived in the ...
Many submarines escaped during the time after an unsuccessful depth charge attack. Since Hedgehog charges explode only on contact, sonar tracking of the submarine is less likely to be disrupted by an unsuccessful Hedgehog attack. Proximity weapons (such as depth charges) need to be set for the target's correct depth to be effective.
On August 11, 2022, British deep-sea divers located the wreck of Jacob Jones off the Isles of Scilly at a depth of 377 feet (115 m). [20] Numerous artifacts were located, including the 80-pound (36 kg) ship's bell. [21] [22] [23] The divers, who found the bell lying on its side, flipped it upright and photographed and filmed it.

The BL 6-inch gun Mark VII (and the related Mk VIII) [h] was a British naval gun dating from 1899, which was mounted on a heavy travelling carriage in 1915 for British Army service to become one of the main heavy field guns in the First World War, and also served as one of the main coast defence guns throughout the British Empire until the 1950s.
