Roketsan Akya
Akya is a new-generation heavyweight torpedo developed by Roketsan for the Turkish Navy. As of 2021, its tests completed, and it went in serial production. "Akya" is the Turkish name of Leerfish. History The heavyweight torpedo project was initiated by the ArMerKom ("Research Center Command") of the Turkish Navy in 2009. Roketsan was signed for the realization. The serial production of Akya started in 2021 after the test firings successfully completed in 2020, which began by July 2013. It is planned that the ''Reis''-class, ''Preveze''-class and ''Gür''-class submarines will be equipped with Akya. It will replace the torpedoes of type Mk 14, Mk 23, Mk 24 (Tigerfish) Mod.2, Mk 37 Mod.2 & Mod.3 and SST-4 Mod.0. AKYA successfully completed its first live firing trial on 27 December 2023, when it was fired from submarine TCG ''Preveze'' and destroyed target ship ex-TCG ''Gazal''. The first delivery to the Turkish Navy was conducted in May 2024. Features Powered by a br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-submarine Warfare
Anti-submarine warfare (ASW, or in the 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 involve 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 instanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Preveze-class Submarine
The Type 209 () is a range of diesel-electric attack submarines developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany. Five class variants (Types 209/1100, 209/1200, 209/1300, 209/1400 and 209/1500), including modifications thereof, have been successfully exported to 15 countries, with 68 submarines being built and commissioned to five different variants between 1971 and 2021. More boats have been built to modified designs. The original variant, the Type 209/1100, was designed in the late 1960s with Greece becoming its first adopter. Turkey is the largest adopter, having purchased 14 submarines consisting of eight Type 209/1400 and six Type 209/1200 submarines. A non-specific variant was adopted by Israel as its first ''Dolphin'' class. The Type 209 family is the most widely proliferated submarine in Latin America, having been adopted by seven countries. Development In the early 1970s, many navies began to need replacements for World War II-era submarin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
K731 White Shark
K731 White Shark () heavy torpedo is a submarine-launched torpedo developed by the Republic of Korea Navy in 2004. Production was delayed for a year after a program error in the guidance system resulted in 2 failed tests in 2003. This glitch was fixed while developing the lighter-weight Blue Shark torpedo. Production cost for each torpedo is at about 950 million won (US$790,000).

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. The homing head shell is a hydrodynamic optimised parabolic shape which aims to reduce torpedo self-noise and cavi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Shark Torpedo
The Black Shark is a heavyweight torpedo developed by WASS of Italy. Development Whitehead Alenia Sistemi Subacquei Italy developed the Black Shark torpedo as an evolution of the A184, with more advanced electronic counter-countermeasures (ECCM) abilities and sonar. The advancements in electric motor design and battery allowed an increase in both range and speed. Features The Black Shark torpedo offers fiberoptic wire for increased bandwidth and signal processing ability compared to copper wire-guided torpedo types. The sonar capability include non-doppler shifted target discrimination and multi-frequency capability that features advanced spatial and angular analysis abilities. The design goal for the torpedo was 300% improvement of passive acquisition and 200% active acquisition with its sonar system.

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 performanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Countermeasure
A countermeasure is a measure or action taken to counter or offset another one. As a general concept, it implies precision and is any technological or tactical solution or system designed to prevent an undesirable outcome in the process. The first known use of the term according to the Merriam-Webster dictionary was in 1923. Countermeasures can refer to the following disciplinary spectrum: * Medicine * Materials engineering * Electro-magnetic engineering * Policing * Information technology * International Law * Diplomatic security * Pollution prevention * Aviation Defense countermeasures are often divided into "active" and "passive". Active "Active" countermeasures mean the system user or the defender takes an active position because the incoming incident is known so the system takes active approaches to deal with such possible damage. Such an approach may include setting up a security method for the incident or actively trying to stop or intersect such damage. Passive "Pass ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances ( ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and sodar (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low ( infrasonic) to e ...

Warhead
A warhead is the section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket (weapon), rocket, torpedo, or bomb. Classification Types of warheads include: *Explosive material, Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. **Conventional weapon, Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. ***Blast wave, Blast: A strong shock wave is provided by the detonation of the explosive. ***Fragmentation (weaponry), Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. ***Continuous-rod warhead, Continuous rod: Metal bars welded on their ends ...

Proximity Fuze
A Proximity Fuse (also VT fuse or "variable time fuze") is a fuse that detonates an explosive device automatically when it approaches within a certain distance of its target. Proximity fuses are designed for elusive military targets such as aircraft and missiles, as well as ships at sea and ground forces. This sophisticated trigger mechanism may increase lethality by 5 to 10 times compared to the common contact fuse or timed fuse. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch, or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching the target or after passing it. At the start of the Bl ...

Electrochemical Cell
An electrochemical cell is a device that either generates electrical energy from chemical reactions in a so called galvanic cell, galvanic or voltaic cell, or induces chemical reactions (electrolysis) by applying external electrical energy in an electrolytic cell. Both galvanic and electrolytic cells can be thought of as having two half-cells: consisting of separate Redox, oxidation and reduction reactions. When one or more electrochemical cells are connected in parallel or series they make a Battery (electricity), battery. Primary battery consists of single-use galvanic cells. Rechargeable batteries are built from #Secondary cells, secondary cells that use reversible reactions and can operate as galvanic cells (while providing energy) or electrolytic cells (while charging). Types of electrochemical cells Galvanic cell A galvanic cell (voltaic cell), named after Luigi Galvani (Alessandro Volta), is an electrochemical cell that generates electrical energy from spontaneous ...
