A depth charge is an anti-submarine warfare (ASW) weapon intended to destroy or cripple a target submarine by the shock of exploding near it. Most use conventional explosives and a fuze set to go off at a preselected depth in the ocean. Depth charges can be dropped by surface ships, patrol aircraft, or helicopters. The depth charge has now largely been replaced by anti-submarine homing torpedoes.
A depth charge fitted with a nuclear warhead is known as a nuclear depth bomb. These were designed to be dropped from a patrol plane or deployed by anti-submarine missile from a surface ship, or another submarine, located a safe distance away. All nuclear anti-submarine weapons were withdrawn from service by the United States, the United Kingdom, France, Russia, and China in or around 1990. They were replaced by conventional weapons that provided ever-increasing accuracy and range as ASW technology improved.

Famous quotes containing the words depth and/or charge:
“Man tells his aspiration in his God; but in his demon he shows his depth of experience; and casts light into the cavern through which he worked his cause up to the cheerful day.”
—Margaret Fuller (1810–1850)
“The Germans are called brutal, the Spanish cruel, the Americans superficial, and so on; but we are perfide Albion, the island of hypocrites, the people who have built up an Empire with a Bible in one hand, a pistol in the other, and financial concessions in both pockets. Is the charge true? I think it is.”
—E.M. (Edward Morgan)
