The RUR-5 ASROC is an all-weather, all sea-conditions anti-submarine missile system. Developed by the United States Navy in the 1950s, it was deployed in the 1960s, updated in the 1990s, and eventually installed on over 200 USN surface ships, specifically cruisers, destroyers, and frigates. The ASROC has been deployed on scores of warships of many other navies, including Canada, Germany, Italy, Japan, Taiwan, Greece, Pakistan and others.
The Mark 24 Tigerfish was a heavyweight acoustic homing torpedo used by the Royal Navy (RN) during the 1980s and 90s. Conceptual development dates to the mid-1950s, and formally started in 1959 with a target introduction date in 1969. A lengthy development process led to a greatly reduced performance requirement, including the removal of anti-surface capabilities. The first prototype "Tiger Fish" examples were delivered in 1967.
The Spearfish torpedo is the heavy torpedo used by the submarines of the Royal Navy. It can be guided by wire or by autonomous active or passive sonar, and provides both anti-submarine warfare (ASW) and anti-surface warfare (ASuW) capability. Spearfish development began in the 1970s, with production starting in 1988, and deployment in 1992. By 2004, the new weapon had completely replaced the older Tigerfish torpedo.
The Mark 48 and its improved Advanced Capability (ADCAP) variant are American heavyweight submarine-launched torpedoes. They were designed to sink deep-diving nuclear-powered submarines and high-performance surface ships.
The Mark 50 torpedo is a U.S. Navy advanced lightweight torpedo for use against fast, deep-diving submarines. The Mk 50 can be launched from all anti-submarine aircraft and from torpedo tubes aboard surface combatant ships. The Mk 50 was intended to replace the Mk 46 as the fleet's lightweight torpedo. Instead the Mark 46 will be replaced with the Mark 54 LHT.
The RUM-139 Vertical-Launch Anti-Submarine Rocket is an anti-submarine missile in the ASROC family, currently built by Lockheed Martin for the U.S. Navy.
The Mark 54 lightweight torpedo is a standard 12.75-inch (324 mm) anti-submarine warfare (ASW) torpedo used by the United States Navy.
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 Mark 44 torpedo is a now-obsolete air-launched and ship-launched lightweight torpedo manufactured in the United States, and under licence in Canada, France, Italy, Japan and the United Kingdom, with 10,500 being produced for U.S. service. It was superseded by the Mark 46 torpedo, beginning in the late 1960s. The Royal Australian Navy, however, continued to use it alongside its successor for a number of years, because the Mark 44 was thought to have superior performance in certain shallow-water conditions.
The Mark 45 anti-submarine torpedo, a.k.a. ASTOR, was a submarine-launched wire-guided nuclear torpedo designed by the United States Navy for use against high-speed, deep-diving, enemy submarines. This was one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare. The 19-inch (483 mm) torpedo was fitted with a W34 nuclear warhead. The need to maintain direct control over the warhead meant that a wire connection had to be maintained between the torpedo and submarine until detonation. Wire guidance systems were piggybacked onto this cable, and the torpedo had no homing capability. The design was completed in 1957, and 600 torpedoes were built before 1976, whereupon ASTOR was replaced by the Mark 48 torpedo.
The Mark 24 mine is an air-dropped anti-submarine (ASW) acoustic torpedo developed by the United States during World War II; it was called a mine to conceal its capabilities. The torpedo entered service with the Allies in March 1943; the United States Navy (USN) used it until 1948. Approximately 4,000 were produced. Of the 340 deployed during the war, 204 were fired, sinking 37 and damaging 18 Axis submarines.
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 with the US Navy during the 1970s, and the stockpiles were sold to foreign navies.
The A244/S is an Italian lightweight, fire-and-forget torpedo employed for anti-submarine warfare. It can be launched from surface vessels or aircraft and locates the target using an acoustic seeker. The torpedo body conforms to the NATO 12.75-inch standard and is compatible with USN Mark 32 torpedo tubes.
Yu-4 (鱼-4) torpedo is the Chinese development of the Russian SAET-50 ASuW passive acoustic homing torpedo, and it is the Russian SAET-50 torpedo incorporating active acoustic homing guidance. Yu-4 torpedo is often erroneously claimed by many sources as the Chinese version of the SAET-60 acoustic homing torpedo, but Soviets had not completed the development of SAET-60 and only fielded the weapon in 1961, by then the relationship between former-Soviet Union and China had already worsened and China had not received any technical assistance on SAET-60 torpedo. The background of the development of Yu-4 torpedo is identical to that of Yu-1 torpedo and Yu-2 torpedo.
Yu-5 (鱼-5) torpedo is the first wire-guided torpedo developed by China. It is an ASW torpedo designed for conventional diesel-electric submarines. It is often erroneously referred as the Chinese copy of Soviet TEST-71 torpedo, which is incorrect as the Soviet torpedo was developed in 1971 and its successor TEST-71MKE was developed in 1977, at the worst time of Sino-Soviet split. With Yu-5 entering Chinese service in 1989, it was simply impossible to acquire any technologies of Soviet TEST-71 torpedo, which was not purchased by China until 1993, four years after the Yu-5 torpedo had already entered service. The Yu-5 is not a product of indigenous development and is based largely upon previous Soviet and American designs, with much of the propulsion system being derived from the American Mark 46 lightweight torpedo.
Yu-6 (鱼-6) torpedo is the Chinese counterpart of the US Mark 48 torpedo, and it is the first domestic Chinese torpedo designed to counter both surface ships and submarines from the very start. Guidance can be by wire, active and passive homing, or wake homing. Domestic Chinese sources have claimed that the Yu-6 torpedo is in the same class as the Mk 48 Mod. 4 torpedo, and it is believed to have been cloned from a captured sample, but official information on the Yu-6 torpedo is limited.
The Yu-7 is a lightweight torpedo developed by the People's Republic of China. It entered service in the 1990s as the principal anti-submarine weapon of major People's Liberation Army Navy (PLAN) warships. The Yu-7 is a derivative of the Whitehead Alenia Sistemi Subacquei (WASS) A244/S torpedo.
There have been a number of 21-inch (53.3cm) torpedoes in service with the Royal Navy of the United Kingdom.
The Mark 21 Mod 2 torpedo, was a passive acoustic homing variant of the Mark 13 torpedo. It used the widely used Mark 13 torpedo as a basis, with the addition of passive acoustic homing developed by Bell Labs.
Multiple 32 cm torpedoes are in use by the Japan Maritime Self-Defense Force, following the adoption of the standard in the second half of the 20th century.
