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 ...

Electrochemical Cell
An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions. The electrochemical cells which generate an electric current are called voltaic or galvanic cells and those that generate chemical reactions, via electrolysis for example, are called electrolytic cells. A common example of a galvanic cell is a standard 1.5 volt cell meant for consumer use. A ''battery'' consists of one or more cells, connected in parallel, series or series-and-parallel pattern. Electrolytic cell An electrolytic cell is an electrochemical cell that drives a non-spontaneous redox reaction through the application of electrical energy. They are often used to decompose chemical compounds, in a process called electrolysis—the Greek word lysis means ''to break up''. Important examples of electrolysis are the decomposition of water into hydrogen and oxygen, and bauxite into aluminium and other chemic ...

Tigerfish Torpedo
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 Tigerfish was fitted with both active and passive sonar and could be remotely controlled through a thin wire which connected it to the launching submarine. Wire guidance permits a torpedo to be launched on-first-warning, i.e. when a target is first detected at long range. This permits the torpedo the time needed to close the range while target course and speed is being updated by the submarine's superior sensors and transmitted 'down-the-wire'. The torpedo can also be reassigned to another target or recalled. Typically, wire-guided torpedoes initially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spearfish Torpedo
The Spearfish torpedo (formally Naval Staff Target 7525) 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. It is one of the most advanced torpedoes in the world. Design The torpedo is driven by a pump-jet coupled to a Hamilton Sundstrand 21TP04 gas turbine engine using Otto fuel II and hydroxyl ammonium perchlorate as oxidiser. The addition of an oxidiser improves the specific energy of the fuel by reducing the fuel-richness of the Otto fuel. The Spearfish, which are capable of travelling at , were designed to catch high-speed, deep-diving Soviet threats such as the . A microprocessor enables the torpedo to make autonomous tactical ...

Mark 48 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. History The Mark 48 was initially developed as REsearch TORpedo Concept II (RETORC II), one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare. The Mk-48 torpedo was designed at the end of the 1960s to keep up with the advances in Soviet submarine technology. Operational since 1972, it replaced the Mk-37, Mk-14 and Mk-16 torpedoes as the principal weapon of U.S. Navy submarines. With the entry into service of the new Soviet in 1977, the decision was made to accelerate the ADCAP program, which would bring significant modifications to the torpedo. Tests were run to ensure that the weapon could keep up with the developments and the weapon was modified with improved acoustics and electronics. The new ve ...

DM2A4
DM2A4 Seehecht (export designation "''SeaHake mod 4''" ) is the latest heavyweight torpedo developed by Atlas Elektronik for the German Navy, as a further update of DM2 (Deutsches Modell 2) torpedo which was released in 1976. Description Being the successor of the DM2A3, it features an advanced electrical propulsion system and a fiber optic cable for torpedo guidance and communication, which, in conjunction with advanced signals processing and mission logic, makes the torpedo largely countermeasure resistant. The DM2A4/SeaHake mod 4 is the first torpedo ever to be guided by a fiber optic wire. With a fully digital system architecture, increased range and speed and its new conformal array sonar with a very wide panoramic sensor angle as well as the additional wake homing sensor, the DM2A4/SeaHake mod 4 provides greatly advanced performance over its predecessor.

Wake Homing
Wake homing is a torpedo guidance technique based on the wake trajectory left behind a moving target. The torpedo is fired to cross behind the stern of the target ship, through the wake. As it does so, it uses sonar to look for changes in the water caused by the passage of the ship, such as small air bubbles. When these are detected, the torpedo turns toward the ship. It then follows a zig-zag course, turning when it detects the outer edge of the wake, to keep itself in the wake while moving forward. This will eventually bring it to the stern of the ship, where its warhead can do the most damage to propulsion and steering. Advantages and disadvantages The system is difficult to jam, but it can be distracted by other ships crossing the wake. In 2013, the US Navy tested prototypes of a system known as the Countermeasure Anti-Torpedo (CAT), which had been designed to intercept and destroy the incoming torpedo. Deployment of the system did not proceed as planned due to performan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
