ET52 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. Development China purchased around 40 Italian Alenia A244-S light ASW torpedoes in 1987 for evaluation and reverse engineering. At the time, China was in the process of working on the license production of the US Mk 46 Mod. 2 torpedo according to the deal first signed between China and the United States in 1985. The 705th Institute (also known as Xi'an Precision Machinery Research Institute, 西安精密机械研究所), tasked to evaluate and reverse engineering the A244-S torpedo, was also responsible for Mk 46 Mod. 2 torpedo program in China, with many of the team members working on both projects. Chinese researchers suggested that since Otto fuel II powered torpedo could cost as much as three times an electrically powered torpedo, the cheaper electrically powere ...

Torpedo
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 naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

A244-S
The A244-s is an Italian lightweight, fire-and-forget torpedo employed for anti-submarine warfare. It can be launched from surface vessels or from aircraft, and locates the target by means of an acoustic seeker. Description 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 by specially emitted pulses and signal processing. The latest version is the A244-S mod.3 torpedo. The A244/s are developed and manufactured by the Italian WASS (Whitehead Alenia Sistemi Subacquei) firm.

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark 46 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 torpedo An aerial torpedo (also known as an airborne torpedo or air-dropped torpedo) is a torpedo launched from a torpedo bomber aircraft into the water, after which the weapon propels itself to the target. First used in World War I, air-dropped torped ...es 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 (RETORC I), one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare.

Export Torpedoes Of China
Export torpedoes of China are Chinese-built torpedoes intended for international export. The series of torpedoes has the prefix "ET" and has been developed by the Chinese marine industrial company CSOC for export only. These torpedoes may have their domestic use correspondence but this is generally not officially admitted. Some of them have seen wide use by the navies of other countries. ^ ''Italics are not officially published parameters'' References {{reflist Torpedoes of China Foreign trade of China ...
