MK-46

Citation :
Torpedoes are self-propelled guided projectiles that operate underwater and are designed to detonate on contact or in proximity to a target. They may be launched from submarines, surface ships, helicopters and fixed-wing aircraft. They are also used as parts of other weapons; the Mark 46 torpedo becomes the warhead section of the ASROC (Anti-Submarine ROCket) and the Captor mine uses a submerged sensor platform that releases a torpedo when a hostile contact is detected. The three major torpedoes in the Navy inventory are the Mark 48 heavyweight torpedo, the Mark 46 lightweight and the Mark 50 advanced lightweight.

The MK-46 torpedo is designed to attack high performance submarines, and is presently identified as the NATO standard. The MK-46 torpedo is designed to be launched from surface combatant torpedo tubes, ASROC missiles and fixed and rotary wing aircraft. In 1989, a major upgrade program began to enhance the performance of the MK-46 Mod 5 in shallow water. Weapons incorporating these improvements are identified as Mod 5A and Mod 5A(S). The MK-46 Mod 5 torpedo is the backbone of the Navy's lightweight ASW torpedo inventory and is expected to remain in service until the year 2015. The MK 46 originated with the RETORC I (Research Torpedo Configuration I) program conducted by the US Naval Undersea Center (NUC) at Pasadena, CA.

MK-48

Citation :


The Mk-48 torpedo is designed to be launched from submarine torpedo tubes. The weapon is carried by all U.S. Navy submarines, including Ohio-class ballistic missile submarines, Seawolf, Los Angeles and Virginia class attack submarines. It is also used on Canadian, Australian and Dutch submarines. The Royal Navy elected not to buy the Mark 48, preferring to use the Spearfish instead.

Mk-48 and Mk-48 ADCAP torpedoes can be guided from a submarine by wires attached to the torpedo. They can also use their own active or passive sensors to execute programmed target searches, acquisition and attack procedures. The torpedoes are designed to detonate under the keel of a surface ship, breaking the ship's back and destroying its structural integrity. In the event of a miss, it can circle back for another attempt.

MK-50

Citation :

The Mk50 torpedo is a highly capable undersea weapon for U.S. Navy surface ships and aircraft. Developed to replace the Mk46 torpedo, it was first authorized for fleet use in October 1992. The Mk50 is designed to counter the fast, deep-diving, double-hulled nuclear submarine threat. Relative to the Mk46, the Mk50 has increased range, more sophisticated counter-countermeasure logic, and greater lethality, speed, depth, and endurance. Major technological advances include a Stored Chemical Energy Propulsion System (SCEPS). Another significant advantage is that the weapon’s tactics and signal processing are software driven. A Mk50 software block upgrade program was conducted in the mid-1990s to enhance the Mk50’s shallow water performance.

MK-54

Citation :
While it has some significant performance deficiencies, the MK 50 is the best air-dropped torpedo in the U.S. Navy inventory, and possibly the best in the world. Unfortunately, quantities of the expensive MK 50 are limited. The Navy currently is developing a Lightweight Hybrid Torpedo (LHT) that combines MK 50 search and homing with a MK 46 propulsion system, in the name of cost-effectiveness. The Lightweight Hybrid Torpedo, MK-54, to be introduced in FY 2003, will further improve the lightweight torpedo inventory performance in shallow water. This program will utilize available components of the MK-46 and MK-50 in addition to extensive use of COTS electronic components.

The LHT, with better sonar and processing capability than the MK 46, will still be handicapped by shortfalls in some characteristics. For this reason, the Navy's current plan to develop the LHT as a relatively cheap substitute for a MK 50 may not yield an operationally effective weapon in a war-fighting scenario without significant improvements in target locating ability and weapons placement accuracy.
The LHT program has been restructured. The restructure includes: shift of LHT IOC to FY03 vice FY01; shift in the testing program to FY99-FY02 from FY98-FY01, with continuation of the RDT&E E&MD contract to completion as originally planned; shift in LRIP to FY00/FY01, vice FY99/FY00; and shift in full rate production to FY02 vice FY01.

Sting Ray

Citation :

Sting Ray is a lightweight torpedo for carriage by aircraft (fixed-wing or rotary) and surface ships for use against submarine targets. It is electrically propelled and powered by a sea water battery which combines low-noise and manoeuvrability with a high speed and deep-diving capability. It is an autonomous weapon which, having received initial, pre-launch, environmental and target information from its launch platform, uses its active sonar and tactical software to search for, localise and prosecute its submarine target. Its tactical software provides the tactical algorithms needed to deal with complex countermeasure scenarios.
Sting Ray Mod 1 is intended to prosecute the same threats as Sting Ray Mod 0 but with an enhanced capability against small clad conventional submarines and an improved shallow-water performance

Spearfish

Citation :

Spearfish is a submarine-launched, heavyweight torpedo (HWT) for use against both surface and submarine targets. It is powered by an open-cycle, bi-propellant gas turbine engine, which provides the weapon with a high sprint speed, a deep-diving capability and high endurance. It is provided with a copper wire command data link to the launch platform but has an inherent capability to operate autonomously.
Once initialised with target and environmental data, the weapon searches for and homes in on the target, using a combination of passive and active sonar, the selection of which is controlled by the weapon's own tactical software. Within this software are tactical algorithms to enable the weapon to deal with complex countermeasure scenarios. The ultimate lethality of the weapon derives from its blast warhead.

LCAW
Citation :

LCAW (Low Cost Anti-submarine Weapon) is a miniature torpedo developed by Whitehead Alenia Sistemi Subacquei S.p.A (WASS). LCAW is developed to fill the gap between conventional depth charge and torpedoes, in the area where depth charges lack propulsion and guidance, while the cost of expansive torpedoes are increasingly becoming prohibitive. The program initially begun in 1987, and completed in 1992. In 1993, the program was adopted by Germany and Norway for their low coast anti-submarine weaponry program when the weaponry proved to meet the German and Norwegian requirement of maximum underwater attack range of 500 m from the point of entry into the water. Norwegians subsequently developed their own upgraded variant. In addition to regular deployment, LCAW is also used by Italian naval special force. The air dropped version is deployed from aerial sonar buoy dispensers. The weapon is primarily designed to engage targets in shallow water, especially midget submarines, swimmer delivery vehicle, human torpedo and other special operation uses.

Torpille d'Asie et de la Russie
APR-3E

Citation :

The APR-3E airborne light ASW acoustic homing torpedo is designed by Russian Tactical Missiles Corporation JSC to engage current and future submarines in at depth from the surface down to 800 metres at speed of up to 43+ kts, and it is a replacement for earlier APR-2 light antisubmarine acoustic homing torpedo.
APR-3E airborne light antisubmarine acoustic homing torpedo is designed to be carried by a various fixed wing and rotary wing platform including Tu-142, Il-38, Ka-28 and other aircraft. The torpedo requires at least 100 metres depth of water for the initial air-drop and can be deployed in conditions up to sea state 6.
Once entering water, the control surfaces of the torpedo enable the torpedo to travel in a spiral path with the help of gravity without starting the engine. During this stage, the acoustic seeker of the torpedo searches for targets. Once the target is identified, the engine starts and solid propellant rocket engine ensures the targets has virtually very little or no time to react, thus increasing the kill probability.

VA-111 Shkval

Citation :
The Shkval ("squall") is a high-speed supercavitating rocket-propelled torpedo designed to be a rapid-reaction defense against U.S. submarines undetected by sonar. It can also be used as a countermeasure to an incoming torpedo, forcing the hostile projectile to abruptly change course and possibly break its guidance wires.
The torpedo has a nearly flat, conical disk at its nose that creates the gas cavity for supercavitation. The disk tilts to help guide the weapon and keep it stable. The cavity is supported by rockets venting just abaft the cavitator. Four popout cylinders toward the aft end of the nose section keep the body of the torpedo stable and out of contact with the walls of the bubble in which it rides. At the rear of the torpedo are deflected control surfaces. Eight small rockets surround the main sustainer rocket. The main engine cuts in when the weapon has achieved supercavitation speed.
The solid-rocket propelled torpedo achieves a high velocity of 230 mph (386 kmh) by producing an envelope of supercavitating bubbles from its nose and skin, which coat the entire weapon surface in a thin layer of gas. This causes the metal skin of the weapon to avoid contact with the water, significantly reducing drag and friction.
The Shkval is fired from the standard 533-mm torpedo tube at a depth of up to 328 ft (100 m). The rocket-powered torpedo exits the tube at 50 knots (93 kmh) and then ignites the rocket motor, propelling the weapon to speeds four to five times faster than other conventional torpedoes. The weapon reportedly has an 80 percent kill probability at a range of 7,655 yd (7,000 m).
The torpedo is guided by an autopilot rather than by a homing head as on most torpedoes. The initial version was unguided. However, the Russians have indicated there is a homing version that starts at the higher speed but slows and enters a search mode.

ET52
Citation :

ET52 torpedo is the Chinese development of the Italian Alenia A244-S light ASW acoustic homing torpedo, and is considered by many domestic Chinese sources as Chinese equivalent of the A244-S Mod. 2 version. ET52 is essentially the A244-S torpedo with technologies of US Mk 46 Mod. 2 torpedo incorporated.
China purchased around 40 Italian Alenia A244-S light ASW torpedo in 1987 for evaluation and reverse engineering.At the time, China was in the process of mastering the license production of the US Mk 46 Mod. 2 torpedo according to the deal first signed between China and USA 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 of electrically powered torpedo, the cheaper electrically powered torpedo should be developed also. The suggestion was accepted, and it was decided to that the technologies of both the Mk 46 Mod. 2 torpedo and A244-S torpedo should be applied to each other to enhance the performance, and 705th Institute (also known as Xi'an Precision Machinery Research Institute, 西安精密机械研究所) was put in charge of A244-S torpedo project in addition to the Mk 46 Mod. 2 torpedo project. Although incorporating the best features to each other certainly improved the performance for both torpedoes, the greatest benefit by far was that due to many shared components, production techniques, and other technologies, the logistic support was significantly reduced and the overall cost was also significantly lowered. A derivative of ET52 has been exhibited at various defense exhibitions by China Shipbuilding Co., and this derivative uses Otto fuel instead of battery

Yu-7
Citation :

According to official information released by the Chinese government, several US Mark 46 torpedoes had been recovered by Chinese fishermen in the 1970’s and 1980’s, with the most advanced version as the Mk 46 Mod. 1 Block 2 torpedo recovered in October, 1978 from South China Sea. Decision was given to reverse the American torpedo under the name “Project 109” to produce the badly needed ASW light torpedo for the Chinese military. 705th Institute (also called Xi'an Precision Machinery Research Institute, 西安精密机械研究所) and Northwestern Polytechnical University were tasked with the research team, while the No. 872 Factory and No. 874 Factory were assigned as the production facility. Full scale development started in 1984, with over 90 enterprises country involved in assisting the 4 major enterprises to develop the torpedo. 705th Institute (also known as Xi'an Precision Machinery Research Institute, 西安精密机械研究所) was the responsible for shallow water control systems of the torpedo and Northwestern Polytechnical University was the responsible for shallow water control systems of the torpedo. The Yu-7 torpedo is consisted of over 5,000 spare parts and 4,500 instruments, while its blueprints numbered over 80,000 and technical documents totaled over 100,000 pages. The first two prototype torpedoes were assembled in No. 874 Factory in December 1984 and tested in the 750 Testing Range (750试验场) in Kunming in December 1985. By 1989 the Yu-7 torpedoes had successfully undertaken 68 launches in four separate sea trials.
In the meantime, the development of Yu-7 torpedo obtained a great boost from USA technical support in 1985, when China signed a US$ 8 million deal with USA in purchasing Mk 46 Mod. 2 torpedoes with technological supports for license assembly. Bush Administration had faced significant criticism from congress and many human rights activists groups for delivering the last batch of Mk 46 Mod. 2 torpedo to China after the Tiananmen Square protests of 1989, but the Bush Administration countered that the delivery was the completion of previous deal prior to the crackdown. Another great benefit to the Yu-7 torpedo program was the Chinese purchase of 40 or so Italian Alenia A244-S light ASW torpedo in 1987, with the 705th Institute assigned to reverse engineer this torpedo as well. The incorporation of technologies of Italian Alenia A244-S light ASW torpedo caused design changes and thus delayed the schedule, but according the western sources such as Jane's Information Group, the biggest factor that caused the delay in the schedule was the difficulties encountered in converting the British system to metric system and American Institute of Electrical and Electronics Engineers standards to international standards. Yu-7 torpedo finally received certification in 1994 and went to full production in late 1990s

Yu-6

Citation :


The Yu-6 is the 533mm wire-/acoustic-/wake-homing heavy torpedo designed by 705 Institute (also known as Xi’an Precision Machinery Institute), a R&D branch of the China Shipbuilding Industry Corporation (CSIC) in Xi’an, Shaanxi province. The Yu-6 is the most advanced and capable indigenous torpedo in service with the People’s Liberation Army Navy (PLAN), designed to engage both deep-diving submarines and surface ships. The torpedo entered the PLAN service in 2005, carried by the Type 039 (Song class) and Type 039A (Yuan class) conventional submarines, and possibly the newly launched Type 093 (Shang class) and Type 094 (Jin class) nuclear-powered submarines too.

In the mid-1980s, the PLAN decided to develop a new heavy torpedo for both anti-ship warfare (ASuW) and anti-submarine warfare (ASW) roles, by reverse-engineering a single Mk-48 torpedo recovered by Chinese fishermen in the late 1970s or early 1980s. The development project was later put on a halt after few prototypes were produced due to enormous technical difficulties and lack of funding. However, research on the Otto fuel II and wire guidance was continued by a small team.

As the PLAN realised that its current torpedoes were unable to meet its requirements for modern naval warfare, the Yu-6 project was officially revived in 1995, with Dong Chun-Peng appointed as the chief designer. The revised Yu-6 design has possibly incorporated some Russian technologies, particularly the unique wake-homing technology. A number of Chinese organisations were involved in the Yu-6 development, including Shanghai Jiaotong University that developed new alloy for the torpedo casing; Tianjin Rubber Research Institute that supplied the noise-reduction casing for the acoustic seeker; Harbin Electro Carbon Research Institute tasked to develop the graphite material used to make engine valves and other components; Yizheng Shuanghuan Piston Ring Co. Ltd. that developed the piston ring for the torpedo propulsion.

It was reported that the Yu-6 adopts a combined wire + active/passive acoustic + waking-homing guidance for different types of targets. It guidance system reportedly uses an Intel 80486-class microprocessor. The Yu-6 was also the first Chinese torpedo designed with the concepts of modular design and open architecture software programming in mind, so that new technologies and programmes could be readily incorporated whenever they become available.

Tu fais un super travail Fremo, maintenant plus personne ne pourra dire qu'il ne sait pas qu'une torpille peut avoir une portée dépassant les 50 km...
Merci rafi
ce sont les asiatiques qui ont la téchnologie des torpilles ayant cette portée à savoir le Japon et la Chine, les russes eux ont la torpille la plus rapide, 200Knts comme vitesse de croisiére, 250Knts Max

VA-111 Shkval

2 anecdotes concernant le Shkval:

1/ la dernière mission du Kursk avant son ''accident'' était la démonstration du Shkval pendant un exercice marin auquel était invitée une délégation chinoise, on dit qu'il y avait aussi des visiteurs ''non souhaitables'' à savoir le Toledo et le Memphis

2/ les iraniens ont semble-t-il réussi à en fabriquer sous licence ou commadé chez la russie discretement, bref... l'essentiel c'est que quand il l'ont testé pour la première fois il l'ont présenté comme étant une invention nationale et ont déclaré qu'ils ont réussi à produire par leur propres moyens la torpille la plus rapide du monde...

En fait c'est la Shkval de 2ème génération qu'il voulait présenté aux chinoix ( la 1ère génération il l'a possède déjà) c'est pourquoi les américains se sont discrètement intéressé aux essais russes..

Mais la visite ''imprévue'' a tourné rapidement au vinaigre... le Kursk charge le Toledo, puis le Memphis charge le Kursk pour défendre son petit frère... la suite vous la connaissez...

Underwater Missile

The supercavitating underwater missile is a technology demonstration program for close-in defence against underwater targets. It is equipped with a solid-propellant rocket motor, inertial measurement unit, autopilot and a conical tip which can be moved by means of an actuator system. The rocket motor provides the missile with a submerged speed of more than 400km/hr. The inertial measurement unit and the autopilot stabilize the missile so that the heading is held. The flexible nose cone provides steering just as a missile's fins do. Due to its high submerged speed, it moves in an air bubble, the so-called cavitation bubble, wherein almost vacuum prevails, thus greatly reducing its water resistance and enabling the high speed. To date, around a dozen test models of the underwater missile have been built and tested successfully. The tests focused on stabilization, guidance and maximization of agility, which is of great advantage for engaging rapidly moving underwater targets. The supercavitating underwater missile is suited for use from submarines and surface vessels.
diehl-bgt-defence

Le missile était appelé ''Barracuda'' mais je pense que le producteur Dieshl BGT Defence a rennoncé à ce nom car le nom n'existe plus sur le site web du producteur Dieshl BGT Defence, alors qu'il était mentionné avant. Sur le site en trouvait le texte ci-dessous qui a maintenant disparu au lieu de celui cité plus haut.

Barracuda

Barracuda is a technology demonstration program for a supercavitating underwater missile for defence against torpedoes and for engagement of submarines. It is equipped with a rocket motor, inertial reference unit/autopilot and a mobile, conus-shaped tip. The rocket motor provides Barracuda with an underwater speed of 360km/hr, the inertial reference unit/autopilot stabilizes the missile and the flexible nose cone provides steering. During underwater travel, Barracuda moves in an air bubble, the so-called cavitation bubble which greatly reduces the water resistance, thus enabling the high speed. Some test models of the underwater missile have been built, successfully demonstrating stable straight and curved path accuracy in several tests. Barracuda will be deployed from submarines and from surface vessels.

j'avais lu un article sur cette torpille qui avait été présenté à l'Euronaval 2008, elle possèderait un système de tracking redoutable casi inleurrable ( d'après ses concepteurs Very Happy )

sa fait moment que je cherhais son nom pour la présenter içi ...bien joué raptor Wink

PS: le barracuda est le nom donné au futur SNA français alors donné ce nom à une torpille sa le faisait pas trop .. Rolling Eyes

De plus tout comme dans le civil il doit y avoir des droits de propriété sur les noms

le Barracuda aussi, si je me rappelle bien, c'est le nom des SM portugais qui date des années 50/60, en cor en service qui sera remplacé par le Type214.

De toute façon le nom ''Barracuda'' a disparu, en cherchant j'ai trouvé le 2ème texte que j'ai posté plus haut dans une ancienne page de forum dna sun post qui date de 2005, mais le lien cité dans ce post donne maintenant le 1er texte.

Raytheon présente un kit d’adaptation GPS pour torpille


Un kit qui ajoute une capacité de guidage par satellite aux torpilles lancées depuis un avion ou un hélicoptère, voila la dernière avancée développée par Raytheon Missile Systems.




Le kit Fish Hawk de Raytheon — que la compagnie présente cette semaine au Singapore Airshow — est conçu pour être installé sur les torpilles légères MK-54 de ce constructeur. Elles sont lancées depuis un avion ou un hélicoptère de lutte anti-sous-marine.
Le kit guide la torpille vers une zone cible grâce au GPS et un système de navigation inertiel. Les informations sur la cible sont fournies par le contrôleur embarqué.
Une fois que le système arrive à basse altitude sur la zone donnée, le kit libère la torpille et un petit parachute la ralentit pour l’entrée dans l’eau.
Les systèmes internes de la torpille prennent alors le relais pour détecter le sous-marin.
Le Fish Hawk est développé par Raytheon pour l’US Navy, un programme destiné à développer de meilleurs armes pour contrer les sous-marins depuis les airs, à haute-altitude.
Il est conçu spécifiquement pour le nouvel avion de lutte ASM de l’US Navy, le Poseidon P-8.

Voici la réponse de LM à Raython, kit pour frappe longue porté ASW.
Destiné aussi à équiper les futurs Poseidons.
Tout comme sa cousine de chez Raython, le kit de chez LM libère la torpille avant immertion.

Terma and DCNS developed fully automatic anti-torpedo decoy system





At the Defense & Security Equipment International exhibition Terma and DCNS announced that their technical cooperation has resulted in an important improvement for ships with a need for protection against torpedoes

Terma and DCNS have developed a fully automatic anti-torpedo decoy system. The system uses the Terma 130mm Soft Kill Weapon System (SKWS) to fire DCNS CANTO-V anti-torpedo decoy. The SKWS upgrade for twin AAW and ASW purpose use the jointly developed software with advanced algorithm (embedding DCNS CONTRALTO-V reaction software) to support fully automatic firing. This provides the ship with an effective protection against torpedoes attacks. The decoys will be placed in the water in the best way to confuse the torpedo together with ship evasive manoeuvres proposal.

With advanced algorithms, this system will provide the best firing solution and protection of all types of ships against torpedo attack.

ATLAS ELEKTRONIK sets new range record for Torpedoes, reaching more than 140 Km

ATLAS ELEKTRONIK has increased the reach of its torpedoes substantially, setting a new range record for torpedoes. At a test-firing in March 2012, the heavyweight torpedo SeaHake® mod4 ER (Extended Range) achieved a range of over 140 kilometres.

SeaHake® mod 4 is the latest advancement of the DM 2 A4 heavyweight torpedo, which is in service with the German Navy as well as the navies of Turkey, Pakistan and Spain. By fully exploiting the system’s unique propulsion and battery technology, it became possible to surpass the maximum ranges usual for modern heavyweight torpedoes in the global market by considerably more than 50%.

“With this record, ATLAS ELEKTRONIK has set a new benchmark in torpedo technology. Until now, such ranges were hardly even conceivable. We are very proud to have made such a significant advance in torpedo technology, thus giving our customers new possibilities for sea defence,” said Kai Pelzer, Executive Director Naval Weapons at ATLAS ELEKTRONIK.

The new version of the SeaHake® mod4 is also fitted with innovative navigation and communications technology, enabling extremely precise navigation and control of the torpedo over the entire distance. The SeaHake® mod4 ER can be deployed from seagoing platforms as well as from special land-based platforms.

The sea trials took place in cooperation with the German Armed Forces Technical Centre for Ships and Naval Weapons in the Eckernförde Bay.

Certain d'entre vous ont'ils déjà entendue parle de torpille imitant un périscope en service dans les années 30/40/50?

Ces torpilles étaient destinées a trompé les navires de surfaces sur le cap est la vitesse su sous-marin attaquant.
