This depth charge contained 200 lb (91 kg) of Torpex. A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarines by detonating in the water near the target and subjecting it to a destructive hydraulic shock.
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]

Mk-101 Lulu NDB (Nuclear Depth Bomb). The Mark 101 Lulu was an airdropped nuclear depth charge developed by the United States Navy and the Atomic Energy Commission during the 1950s. It carried a W34 nuclear warhead, with an explosive yield of about 11 kilotons.
A nuclear depth bomb is the nuclear equivalent of a conventional depth charge, and can be used in anti-submarine warfare for attacking submerged submarines.The Royal Navy, Soviet Navy, and United States Navy all had nuclear depth bombs in their arsenals at one point.
Until depth-finding sonar became available (the first was the Royal Navy's Q attachment in 1943), there was a "dead period" during the final moments before a depth-charge attack began when contact with the target would be lost. U-boat commanders became adept at sharp course changes and direction speed at these moments to break contact and escape.
High Blast Explosive, or HBX, is an explosive used as a bursting charge in missile warheads, mines, depth bombs, depth charges, and torpedoes. History
USS Cony, which first detected the sub, USS Beale and other destroyers began dropping signalling depth charges of the type used for naval training, which contained very little charge and were not intended to cause damage. [21] Messages from the US Navy stating the type of depth charges being used did not reach B-59 or, it seems, Soviet naval HQ.
