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 uses a CIACIO-S seeker, consisting of an acoustic homing head containing the transducer assembly, transmitter, and related Beamforming circuits, and a frame housing all the remaining electronic components. The homing head is capable of active, passive, or mixed modes for closing onto its target. It can also discriminate between decoys and real targets in the presence of heavy reverberations especially emitted pulses and signal processing.
The latest version is the A244-S mod.3 torpedo, manufactured by Leonardo. [1]

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.
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a fish. The term torpedo originally applied to a variety of devices, most of which would today be called mines. From about 1900, torpedo has been used strictly to designate a self-propelled underwater explosive device.
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 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.
The Delhi-class destroyers are guided-missile destroyers of the Indian Navy. Three ships of this class are in active service. The Delhi-class vessels were the largest vessels to be built in India at the time of their commissioning. The ships were built by Mazagon Dock Limited (MDL) at a cost of ₹750 crore each.
The MU90 Impact is a Franco-Italian advanced lightweight anti-submarine torpedo of the third generation developed for the French and Italian navies, as well as for export. It is designed to outperform the United States-built Mark 54 in and was developed in a special MU90 Hard Kill version for anti-torpedo defence. It is built by EuroTorp, a consortium of French and Italian companies.
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 Laksamana class is a class of small missile corvettes comprising four ships currently in service with the Royal Malaysian Navy. All four ships of the Laksamana class are currently serving in the 24th Corvette Squadron of the Royal Malaysian Navy.
DM2A4 Seehecht is the latest heavyweight torpedo developed by Atlas Elektronik for the German Navy, as a further update of DM2 torpedo which was released in 1976.
The APR-3E airborne light ASW acoustic homing torpedo is designed by Russian Tactical Missiles Corporation JSC to engage current and future submarines at depth from the surface down to 800 metres at speed of up to 43+ knots, and it is a replacement for earlier APR-2 light antisubmarine acoustic homing torpedo.
Yu-2 torpedo was a Chinese development of the unguided straight-running Soviet ASuW RAT-52 torpedo with passive acoustic homing capability added. The historical background of Yu–2 is identical to that of Yu-1 torpedo and Yu-4 torpedo. Contrary to the higher number assigned, Yu-2 torpedo was the first Chinese domestically produced torpedo entering service, ahead of the Yu-1 torpedo.
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.
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.
The ET52 torpedo is the Chinese development of the Italian Alenia A244-S light ASW acoustic homing torpedo. It is considered by some to be an A244-S torpedo with technologies similar to a US Mk 46 Mod. 2 torpedo.
The Torpedo Advanced Light (TAL) Shyena is the first indigenous advanced lightweight anti-submarine torpedo of India, developed by the Naval Science and Technological Laboratory (NSTL) of the Defence Research and Development Organisation (DRDO) for the Indian Navy. The lightweight torpedo can be launched by ships, helicopters and previously the now retired Ilyushin Il-38, named after the divine hawk identified with Agni.
The K745 Blue Shark is a light anti-submarine torpedo developed for the Republic of Korea Navy in 2004.
The Type 97 Torpedo is a short-range torpedo developed and built by the Mitsubishi Heavy Industries for the Japanese Maritime Self Defense Force. This type of torpedo, like many other modern Japanese weapons systems, is not exported.
