A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive hydraulic shock. Most depth charges use high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters.
The Aichi B7A Ryusei was a large and powerful carrier-borne torpedo-dive bomber produced by Aichi Kokuki for the Imperial Japanese Navy Air Service during the Second World War. Built in only small numbers and deprived of the aircraft carriers it was intended to operate from, the type had little chance to distinguish itself in combat before the war ended in August 1945.
The Type 93 was a 610 mm (24 in)-diameter torpedo of the Imperial Japanese Navy (IJN), launched from surface ships. It is commonly referred to as the Long Lance by most modern English-language naval historians, a nickname given to it after the war by Samuel Eliot Morison, the chief historian of the U.S. Navy, who spent much of the war in the Pacific Theater. In Japanese references, the term Sanso gyorai is also used, in reference to its propulsion system. It was the most advanced naval torpedo in the world at the time.
Kaiten were crewed torpedoes and suicide craft, used by the Imperial Japanese Navy in the final stages of World War II.
The Mark 46 torpedo is the backbone of the United States Navy's lightweight anti-submarine warfare torpedo inventory and is the NATO standard. These aerial torpedoes are designed to attack high-performance submarines. In 1989, an improvement program for the Mod 5 to the Mod 5A and Mod 5A(S) increased its shallow-water performance. The Mark 46 was initially developed as Research Torpedo Concept I, one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare.
Type 53 is the common name for a family of 53 cm torpedoes manufactured in Russia, starting with the 53-27 torpedo and continuing to the modern UGST (Fizik-1), which is being replaced by the Futlyar.
The Type 91 was an aerial torpedo of the Imperial Japanese Navy. It was in service from 1931 to 1945. It was used in naval battles in World War II and was specially developed for attacks on ships in shallow harbours.
The VA-111 Shkval torpedo and its descendants are supercavitating torpedoes originally developed by the Soviet Union. They are capable of speeds in excess of 200 knots.
The Sting Ray is a British acoustic homing lightweight torpedo (LWT) manufactured by GEC-Marconi, who were later bought out by BAE Systems. It entered service in 1983.
The G7a(TI) was the standard issue Kriegsmarine torpedo introduced to service in 1934. It was a steam-powered design, using a wet heater engine burning decaline, with a range of 7,500 metres (24,600 ft) at 40 knots speed. In 1936, the Kriegsmarine's first electrical powered torpedo was introduced with the G7e(TII). It was replaced beginning in 1942 by the G7e(TIII). The G7a(TI) remained in service as the main torpedo of Kriegsmarine for the length of the war, being the only torpedo used from surface vessels, and alongside electric torpedoes on the uboats.
The I-201-class submarines were submarines of the Imperial Japanese Navy during World War II. These submarines were of advanced design, built for high underwater speed, and were known as Sentaka-Dai type submarine or Sentaka type submarine. The type name, was shortened to Suichū Kōsoku Sensuikan Ō-gata.
The Mark 37 torpedo is a torpedo with electrical propulsion, developed for the US Navy after World War II. It entered service with the US Navy in the early 1950s, with over 3,300 produced. It was phased out of service key with the US Navy during the 1970s, and the stockpiles were sold to foreign navies.
The Mark 16 torpedo was a redesign of the United States Navy's standard Mark 14 torpedo in use during World War II. It incorporated war-tested improvements into a weapon designed to be used in unmodified United States fleet submarines. Due to high unit cost and the Mark 14's unreliability issues being solved by mid-1943, they were never put into mass production.
The Imperial Japanese Navy Technical Department was the externally operating division of the Ministry of the Navy of Japan responsible for the administration of naval vessel construction. From 1923 onward, it took on the role of a research institution for the research and development of naval technologies and engineering. This included studying and investigating existing western naval technology, developing and overseeing Japan's domestic shipbuilding and arms industries, and training officers to become naval engineers and inspectors. The bureau was dismantled along with the naval ministry in November 1945 after Japan surrendered to the Allies at the end of World War II.
There have been a number of 18-inch torpedoes in service with the United Kingdom.
The Ibuki-class cruisers were the last class of heavy cruisers built for the Imperial Japanese Navy (IJN). In order to save design time, the ships were essentially repeats of the earlier Mogami class. Begun during World War II, only the lead ship, Ibuki, was launched, but she was in the process of being converted into a light aircraft carrier when construction was suspended in 1945. She was scrapped the following year. The unnamed second ship was scrapped less than a month after being laid down in order to clear her slipway for an aircraft carrier.
There have been several British 21-inch (533 mm) torpedoes used by the Royal Navy since their first development just before the First World War.
This is a list of Active Royal Navy weapon systems.
A nuclear torpedo is a torpedo armed with a nuclear warhead. The idea behind the nuclear warheads in a torpedo was to create a much bigger explosive blast. Later analysis suggested that smaller, more accurate, and faster torpedoes were more efficient and effective.
The Japanese submarine I-5 was the first aircraft-carrying submarine in the Imperial Japanese Navy and operated during World War II. The sole member of the Junsen 1 Mod. (巡潜一型改) class, the submarine was launched on 19 June 1931 at Kobe by Kawasaki. A single Yokosuka E6Y floatplane was carried. A catapult was fitted in 1938 but the capability to operate the aircraft was removed two years later and the boat was reconfigured as an attack submarine. By that time, I-5 had already seen wartime service.
