Drones de guerre des mines : Notification du marché franco-britannique MMCM

Drones de guerre des mines : Notification du marché franco-britannique MMCM | Newsletter navale | Scoop.it

Le 27 mars 2015, les agences d’acquisition des ministères de la Défense français et britannique, respectivement la Direction générale de l’armement (DGA) et DE&S, ont notifié le contrat « Maritime Mine Counter Measures » (MMCM).

Cette notification est le résultat d’un dialogue compétitif conduit par l’OCCAR (Organisation conjointe de coopération en matière d’armement). Ce contrat est attribué à Thales associée à BAE Systems avec parmi les sous-traitants français le groupe ECA. Il permet à la France et au Royaume-Uni d’initier conjointement le développement d’une nouvelle capacité stratégique et interopérable entre nos deux marines, tout en maintenant leur industrie au meilleur niveau mondial dans le domaine de la lutte sous-marine.

Le contrat notifié au consortium industriel porte sur la définition, la réalisation et la qualification de deux prototypes d’un système de drones navals, de surface et sous-marins, d’ici 2019. Ils seront mis en œuvre à partir d’un « bateau mère » ou depuis la terre. Les évaluations seront conduites par la Marine nationale et la Royal Navy. Par comparaison aux chasseurs de mines actuels, le système permettra de maintenir l’homme en dehors de la zone de danger.

La Marine japonaise met en service le 1er hélicoptère MCH-101 de KHI spécialisé dans la guerre des mines | Newsletter navale | Scoop.it

Finmeccanica – AgustaWestland and Kawasaki Heavy Industries (KHI) are pleased to announce the delivery of the first Airborne Mine Counter Measures (AMCM) equipped MCH-101 helicopter to the Japan Maritime Self Defense Force. The KHI MCH-101, a licence built version of the AgustaWestland AW101 helicopter, is equipped with the Northrop Grumman AN/AQS-24A airborne mine hunting system and the Northrop Grumman AN/AES-1 Airborne Laser Mine Detection System (ALMDS). Together these systems provide a complete surface-to-bottom mine detection capability. The AW101/MCH-101 is one of only two helicopter types capable of towing the AN/AQS-24A and the only modern helicopter type.

The development of the AMCM variant of the AW101/MCH-101 has been led by Kawasaki Heavy Industries, as prime contractor, with AgustaWestland providing technical support. KHI has responsibility for system integration and design of the AN/AQS-24A carriage, deploy, tow and recovery system that is installed in the cabin. AgustaWestland in addition to providing technical support also modified the aircraft’s Automatic Flight Control System (AFCS) to be able to perform coupled towing patterns with the AN/AQS-24A.
Following the handover ceremony at Kawasaki’s Gifu factory on 27th February, the Japan Maritime Self Defense Force aircraft was delivered to Iwakuni where it will perform evaluation trials with the 51st Experimental Squadron before entering operational service in 2016.
The AN/AQS-24A is the only operationally proven, high speed airborne mine hunting system in the world. It features a high-resolution, side scan sonar for real time, detection, localization and classification of bottom and moored mines at high area coverage rates and a laser line scanner to provide precision optical identification of underwater mines and other objects of interest.
The AN/AES-1 Airborne Laser Mine Detection System (ALMDS) uses pulsed laser light and streak tube receivers housed in an external equipment pod to image the entire near-surface volume potentially containing mines. The ALMDS pod is mounted on the port weapon carrier and data is displayed on the cabin mission console.
The first AMCM configured is the eighth of 13 AW101s that Kawasaki Heavy Industries is building under licence from AgustaWestland for the Japan Maritime Defense Force. The eight aircraft delivered to date comprise six MCH-101s and two CH-101s. The CH-101s are used to support Japan’s Antarctic research activities.

L'Inde finance la construction d'une nouvelle flotte de 12 chasseurs de mines sur son chantier GSL de Goa

L'Inde finance la construction d'une nouvelle flotte de 12 chasseurs de mines sur son chantier GSL de Goa | Newsletter navale | Scoop.it

India's Defense Acquisition Council (DAC) has awarded INR 30,000 crore (US$4.8 billion) contract for 12 mine countermeasure vessels (MCMV) or minesweepers to Goa Shipyard.

Last November, Defense Ministry had scrapped INR 2,700 crore (US$4.3 billion) for acquiring eight minesweeper vehicles from South Korean firm, Kangnam after the firm had employed middlemen, which is a violation of the tender conditions.

Earlier last year, the deal for eight MCMV from South Korean firm Kangnam Corporation were scraped as Defence Minister Manohar Parrikar discussed the idea of giving the order to Goa Shipyard.

Northrop Grumman livre de nouveaux "Mission Packages" spécialisés lutte de surface et guerre des mines pour les LCS

Northrop Grumman livre de nouveaux "Mission Packages" spécialisés lutte de surface et guerre des mines pour les LCS | Newsletter navale | Scoop.it

Northrop Grumman Corporation has received a $21.6 million contract from the U.S. Navy for two additional Littoral Combat Ship (LCS) mission packages. As the mission package integrator, the company will deliver one mission package for surface warfare and one for mine countermeasures.

The capabilities contained in the various mission modules directly support the three LCS primary missions – surface warfare, mine countermeasures and antisubmarine warfare. Mission modules facilitate efficient modular mission package embarkation, mission package operations at-sea, and debarkation / logistics support.

"As the mission package integrator for LCS we are committed to meeting the demanding requirements of our warfighters, while providing supplier base stability and reducing cost to the Navy," said Doug Shaffer, director, electronic attack/maritime systems integration programs, Northrop Grumman Aerospace Systems. "As more Littoral Combat Ships enter service, the U.S. Navy/Northrop Grumman team has stepped up to make sure the mission modules are available when needed to achieve initial operational capability (IOC)."

Northrop Grumman has delivered three mine countermeasures and three surface warfare mission modules for LCS. A fourth mine countermeasures mission module is in production and scheduled for delivery in 2015. The fourth and fifth surface warfare mission modules are also in production and scheduled for delivery in early 2015. Northrop Grumman performs the final integration work and completes delivery at the Mission Package Support Facility located at Naval Base Ventura County, Port Hueneme, Calif.

Northrop Grumman débute la production série du système laser détection mines ALMDS pour l'hélicoptère MH-60S des LCS

Northrop Grumman débute la production série du système laser détection mines ALMDS pour l'hélicoptère MH-60S des LCS | Newsletter navale | Scoop.it

WASHINGTON, 30 Dec. 2014. Ocean mine warfareexperts at the Northrop Grumman Corp. Aerospace Systems segment in Melbourne, Fla., will provide the U.S. Navy with a helicopter-based system designed to detect floating and submerged ocean mines with laser beams under terms of a potential $163.6 million contract announced last week.

Officials of the Naval Sea Systems Command in Washington awarded a $35.5 million contract to Northrop Grumman two days before Christmas to build and support the AN/AES-1 airborne laser mine detection systems (ALMDS).

The ALMDS electro-optical system will be mounted on Navy MH-60S helicopters based on the littoral combat ship (LCS). The laser-based mine-detection system uses streak tube imaging light detection and ranging (LIDAR) sensors to detect, classify, and localize surface and near-surface moored sea mines.

The ALMDS provides a revolutionary, high-area-coverage-rate capability that is organic to -expeditionary and carrier strike groups, Navy officials say. This contract includes options which, if exercised, would bring the cumulative value of this contract to $163.6 million.

The system, which will be part of the mine countermeasures (MCM) mission package aboard the new LCS, is designed for rapid wide-area reconnaissance and assessment of anti-ship mines in coastal waters, harbors, confined straits, choke points and amphibious assault areas where aircraft carriers and expeditionary strike groups must operate.

The ALMDS uses pulsed laser light and streak tube receivers housed in an external equipment pod on the MH-60 helicopter. These lasers are designed to search the water column from the surface to about 40 feet in depth -- the area where mines are the biggest threats and coincidentally where mine-hunting sonar systems are least effective. The system takes an image of the entire near-surface water column potentially containing mines.

The ALMDS projects a pulsed wide 538-nanometer blue-green laser beam into the water and samples at rates greater than 100 per second. ALMDS is capable of day or night operations without stopping to stream out or recover equipment and without towing any equipment in the water. It uses the forward motion of the aircraft to generate image data negating the requirement for complex scanning mechanisms.

The system is contained in a pod mechanically attached to the MH-60S with a standard Bomb Rack Unit 14 (BRU-14) mount and electrically via a primary and auxiliary umbilical cable to the operator console. Data is stored on a mass memory unit, and the ALMDS operator's console is common to all MH-60S airborne mine countermeasures systems.

The ALMDS was designed with VMETRO central electronics chassis (CEC) ---- liquid-cooled air transportable rack (ATR) systems with VMETRO CSW1 6U VXS (VITA 41) switch cards and VPF1 quad processor payload cards. The Curtiss-Wright Corp. Defense Solutions division in Santa Clarita, Calif., acquired VMETRO in 2008.

The CSW1 and VPF1 embedded computing boards process image sensor data using real-time multiprocessing over high-speed serial communications. The ALMDS CEC uses a combination of field-programmable gate arrays (FPGAs) and PowerPC processors.

Les LCS de l'US Navy effectuent des essais de "Mission Packages" guerre des mines et ASM (notamment un sonar remorqué)

Les LCS de l'US Navy effectuent des essais de "Mission Packages" guerre des mines et ASM (notamment un sonar remorqué) | Newsletter navale | Scoop.it

The Navy’s Littoral Combat Ship recently searched for submarines and sailed through a dummy mine-field off the coast of San Diego, California, to assess whether the vessel’s anti-submarine and mine-countermeasure technologies could find enemy submarines and successfully detect and destroy underwater mines, service officials said.

The anti-mine developmental and operational tests this past summer took place on board the USS Independence, or LCS 2. The tests involved many aspects of the LCS’ Mine-Countermeasures mission package, a collection of integrated mine-detecting technologies engineered to swap on and off the platform.

“The real purpose of the test was to stress the operational tempo. This is the first time we’ve really done end to end missions on the ship,” Capt. Casey Moton, LCS mission modules program manager, said.

Using a suite of counter-mine technologies, the ship traveled twice through the mock-mine field, successfully detecting the mines in each instance. The test was the first time all three elements of the MCM package were integrated on-board the ship, Moton explained.

The elements consist of a Remote Mine-hunting System below the surface and an Airborne Laser Mine Detection System, or ALMDS, above the water to locate the mines alongside an Airborne Mine Neutralization System, or AMNS, designed to destroy the mines once they are found, he added.

“We wanted to be sure the crew could handle a high-tempo. The crew did extremely well operating through the different stages – search, detect, destroy,” Moton said.

The RMS is comprised of an AQS-20 underwater sonar mine detection system which launches from an autonomous semi-submersible called the Remote Multi-Mission Vehicle, or RMMV.  The RMMV, which has both line-of-sight and over-the-horizon capability, is launched from the back of the LCS, Navy officials said.

As many as two RMMVs can operate from the LCS at one time.  The RMS works in tandem with the ALMDS, an airborne laser designed to scan the surface and shallow water for mines.  Data from both the RMS and ALMDS are assessed at a command center on-board the ship, he said.

“They will basically piece all that together to get a complete picture of where all the mines are. Air assets and the RMS are looking at two different things. The air assets are looking for mines near the surface and the RMS is looking for mines deeper in the water,” Moton explained.

The AMNS involves the use of an MH-60 helicopter which drops a vehicle into the water carrying neutralizer to blow up a mine that has previously been found.

The Navy is now in the process of further analyzing the results of the tests.

“I have to crunch all the data now and see what needs to be worked,” he added.

The MCM package is slated to be operational on board the USS Independence by next summer, Moton said.

Upon initial examination, anti-submarine and counter-mine warfare might seem to call upon the same detection technologies and methods.  Moton explained, however, that while there are some similarities, detecting submarines is actually much different that finding mines.

“Mines are harder to find. They don’t radiate any noise and the ranges are shorter. The sonars that are going against submarines have to be much longer range. A submarine is putting out its own noise signature,” Moton explained.

The Navy also recently finished testing of its Anti-Submarine Warfare mission package in September off the coast of San Diego, Calif., on board the USS Freedom, Moton said.

The ASW mission package, slated to be operational by 2016, is earlier in its development than the other two LCS mission packages, the Surface Warfare and Mine-Countermeasures mission packages.

The technologies for the ASW package include use of an active sonar called Variable Depth Sonar deployed off the back of the ship and a passive detection system called a Multi-Function Towed Array, or MFTA.

“We were towing an active and passive detection sonar. This was the first time where we had done a test on LCS where we had towed both of those systems,” Moton said.

An active sonar pro-actively sends out a “ping” or acoustic signal and then analyzes the return to determine the shape, distance and dimension of a given threat; passive sonar is merely listening or receiving pings.

The tests, which included detecting actual submarines, involved mechanical assessments at different speeds to make sure the two systems did not cross, Moton said.

The ASW package also uses MH-60 helicopters to detect and destroy submarines with sonobuoys and lightweight torpedos.

Light Weight Tow torpedo countermeasures, vertical-take-off-and-landing unmanned aerial vehicles and handling gear for the equipment are also parts of the ASW mission package, Navy officials said.

Moton said the Navy is exploring options for acquiring lighter weight handling gear for the ASW package on-board the LCS.

Textron obtient un contrat de 34 millions de $ pour le véhicule surface autonome de guerre des mines des corvettes LCS

Textron obtient un contrat de 34 millions de $ pour le véhicule surface autonome de guerre des mines des corvettes LCS | Newsletter navale | Scoop.it

A division of Textron Systems has won a $33.8 million Navy contract for an unmanned surface vehicle designed to sweep for acoustic and magnetic mines from the Littoral Combat Ship (LCS), company officials told USNI News last week.

The Unmanned Influence Sweep System (UISS previously known as the unmanned surface sweep system or USSS) is planned for the Mine Countermeasure (MCM) mission package planned for the Littoral Combat Ship (LCS).

The USV is designed to methodically sweep a patch of ocean towing a cable designed to trigger so-called influence mines — mines that activate when they detect sounds or magnetic signatures that correspond to those of a large ship.

“It’s a cable that you tow behind the USV,” Rear Adm. John Ailes, former program manager for LCS Mission Modules, told USNI News in 2013.

“It provided both acoustic — making noise like a ship — and the magnetic signature of a ship… It tells the mines, ‘I’m a ship, you should blow up’.”

UISS is based on Textron Systems Unmanned Systems’ Common Unmanned Surface Vessel (CUSV) the company has been testing for years, Bill Leonard of Textron Systems Unmanned Systems told USNI News.

“We started doing all of our lessons learned and came up with a fourth generation of our CUSV,” Leonard said.
“We made improvements to the hull form, we made the payload bay larger. Got a new propulsion system and just various other improvements that we’ve learned over the five or six years we’ve been doing this and that translate over to the Navy program.”

Textron now has two years to finalize the development of the UISS before a 2017 test of the MCM package.

The contract has a potential value of $118 million, according to a Sept. 30 Pentagon contract award under the Textron unit’s old name, AAI Corp.

UISS is planned for the third increment of the MCM package.

The first increment of the MCM package — designed to find and neutralize less complex but more plentiful contact mines — is slated to be tested onboard USS Independence (LCS-2) next year.

La Chine aurait testé un drone sous-marin UUV en exercice de guerre des mines

La Chine aurait testé un drone sous-marin UUV en exercice de guerre des mines | Newsletter navale | Scoop.it

China has completed a naval exercise in the South China Sea that could help it to counter Taiwanese defenses in the event of an invasion.

The exercise was aimed at neutralizing the types of anti-ship “smart mines” that Taipei has been developing over the past year.

A spokesperson for China’s People’s Liberation Army Navy (PLAN) said Chinese warships were able to find and detonate the mines from “hundreds of meters away.”

A US military source said this development is something that should “certainly concern” Taiwan.

US military advisers have been encouraging Taiwan to develop “smart mines” as a significant part of the nation’s anti-invasion defenses.

The Taipei Times reported in December 2012 that a new generation of “smart mines” was being developed for deployment in shallow water close to the coast, where they would be more effective in stopping enemy landings.

The report said that Taiwan’s west coast features a large number of estuaries — adding to the nation’s vulnerability — as an attacker would not have to invade across beaches, but can move upriver and disembark inland.

While the smart mines remain classified, it was reported that a budget had been approved for their development beginning last year.

It is understood that the mines are hidden on the ocean floor and can be remotely activated to detect enemy ships by their electronic and magnetic signals.

When an enemy ship comes close to a mine, it explodes.

Craig Hooper, a former teacher at the US Naval Postgraduate School in Monterey, California, has reported that the Chinese navy conducted its drills in formation for the first time.

The drills were carried out by ships from the Nanhai Fleet.

“The garrison approached the mines in varied formations corresponding to different conditions. After hours of searching, the flotilla discovered a number of smart mines hundreds of meters away and detonated them upon the commander’s order,” Hooper quoted Xinhua news agency as saying.

Chinese military specialist with the US International Assessment and Strategy Center Richard Fisher told the Taipei Times that the PLAN had one of the largest naval mine inventories in the world for use in both offensive and defensive operations.

Fisher said that over the past decade, the Chinese navy had made much greater investment in counter-mine technologies and new mine-sweeping ships.

“During both blockade or invasion operations against Taiwan, the PLAN will likely employ thousands of naval mines,” Fisher said. “They would be placed in minefields that block off both ends of the Taiwan Strait, as well as outside major Taiwanese ports. The PLA Navy even has torpedo-propelled mines that could swim inside a port and rest on the harbor bottom.”

Fisher was able to throw some light on the possible method used by PLAN to find and destroy “smart mines.”

“For about four years, the PLA Navy has been using a new small counter-mine unmanned underwater vehicle [UUV] to both find and dispatch mines, either by moored type or bottom-dwelling mines,” he said. “Such a UUV would allow the PLA Navy minesweepers to detonate smart mines hundreds of meters from their ship.”

Cérémonie de 1ère mise à l'eau du nouveau dragueur de mines russe Alexander Obukhov (Projet 12700)

MOSCOU, 26 juin - RIA Novosti

 La Marine russe recevra d'ici 2018 quatre dragueurs de mines dernier cri (projet 12700), le premier navire devant entrer en service en 2015, a annoncé jeudi le ministère russe de la Défense dans un communiqué.

 Le dragueur de mines de nouvelle génération Alexandre Oboukhov, construit par  les chantiers navals Sredné-Nevski de Saint-Pétersbourg, sera mis à l'eau vendredi, selon le communiqué.

 "Le dragueur de mines Alexandre Oboukhov est le navire amiral de la série. En avril 2014, le ministère de la Défense a signé un contrat de construction de trois navires de ce projet qui devraient être livrés d'ici 2016-2018", indique le communiqué.

 Le dragueur de mines Alexandre Oboukhov est destiné à la Flotte russe du Nord et pourrait entrer en dotation fin 2015.

 Long de 61 mères et large de 10 mètres, le navire a un déplacement de 890 tonnes. Sa vitesse est de 16,5 nœuds et l'équipage se compose de 44 personnes.

 Pour lutter contre les mines, le navire est doté de divers types de dragues ainsi que d'appareils sous-marins téléguidés.


Patrick H. 's insight:

Source "Le Marin" (janvier 2014) :

Les chantiers SNSZ de Saint-Pétersbourg ont annoncé la construction d’un dragueur de mines de 62,50 mètres en fibre de verre. Il devrait entrer en service en 2015. Vendu pour une vitesse de 15 noeuds, l’Alexandrit pourra accueillir 41 membres d’équipage pour une autonomie de 10 jours. Avec un déplacement de 800 tonnes, ce navire est construit par infusion sous vide, ce qui est une performance technique. Si les raisons de l’utilisation de matériaux composite pour des dragueurs de mines sont évidentes (ils réduisent au maximum les perturbations électromagnétiques), il faut souligner le peu d’entretien dont la structure du navire a besoin, comparé à un navire coque acier.

La Marine indienne intéressée par le véhicule sous-marin autonome Adamya de L&T déployable par TLT

La Marine indienne intéressée par le véhicule sous-marin autonome Adamya de L&T déployable par TLT | Newsletter navale | Scoop.it

February 17, 2014: The Indian Navy is now keenly tracking an advanced programme unveiled at the recently concluded Defexpo event: the Adamya autonomous underwater vehicle (AUV) developed and built in-house by L&T Heavy Engineering. While the navy has a stated requirement for AUVs, the Adamya has caught its attention for a reason. According to L&T, "Adamya is the next step into the world of unmanned naval warfare and coastal defence. Its unique design allows it to be launched from the torpedo tube of a submarine—a pioneering feat globally."

L&T has highlighted several features on the Adamya to the Navy, including the fact that the vehicle's modular design and depth-rated shells enable mission customisation as per the Navy's needs without having to resort to pressure-proofing of the internal electronic systems. Other qualities include short turnaround time and ability to be air-shipped conveniently. The Adamya is being pitched for naval applications that include hydrographic survey (the Hydrography Dept. incidentally is also looking for AUVs), mine countermeasures, intelligence-surveillance-reconnaissance (ISR), offshore survey, clandestine monitoring, environmental monitoring and optional anti-submarine warfare. The 18.7 feet, 850 kg platform sports an endurance of 8 hours at 4 knots (with maximum forward speed of 6 knots) with a customisable depth rating of 500 metres.

Kongsberg a débuté la production de série de planeurs sous-marins Seaglider

Kongsberg a débuté la production de série de planeurs sous-marins Seaglider | Newsletter navale | Scoop.it

Kongsberg Maritime subsidiary Kongsberg Underwater Technology, Inc. (KUTI, USA) has started full-scale production of the Kongsberg Seaglider autonomous underwater vehicle (AUV) from a new fabrication centre at its facility in Lynnwood, WA, USA. This follows KUTI’s acquisition of the exclusive licence to develop, manufacture and market the innovative Seaglider system from the University of Washington in May 2013.

Seaglider was developed at the University of Washington in Seattle with funding from the U.S. Office of Naval Research. It is an autonomous underwater vehicle (AUV), or underwater glider, developed for continuous, long-term measurement of oceanographic parameters. Rather than an electrically driven propeller, the vehicle uses small changes in buoyancy and wings to achieve forward motion. The system's pitch and roll are controlled using adjustable ballast, which is actually the vehicle’s battery. This unique approach enables deployment for up to nine months at a time.

Since obtaining the technology license, KUTI has been establishing an engineering, production and support operation for manufacturing the Kongsberg Seaglider, at its Lynnwood facility, which is just 12 miles north of the University of Washington. The Kongsberg Seaglider Team has completed extensive training with the university’s Seaglider Fabrication Center personnel. In addition to manufacture of new Seaglider vehicles, the facility is also performing refurbishment or upgrade of existing systems.

Rich Patterson, general manager Underwater Glider Systems at Kongsberg Underwater Technology Inc, said that in six months they have been able to establish an engineering and production group, and they are busy fulfilling orders for several systems that will be shipped during the first half of the year.

As the first vehicle from the new Kongsberg Maritime business unit, Underwater Glider Systems, Kongsberg Seaglider is capable of deploying a diverse range of sensors making it a cost effective instrument for collecting a wide variety of ocean data. Kongsberg Maritime is committed to developing additional capabilities for its new AUV whilst at the same time working on transition of the technology into the commercial sector.

Les nouveaux patrouilleurs hauturiers irlandais vont mettre en oeuvre des drones aériens et des mini sous-marins téléopérés

Les nouveaux patrouilleurs hauturiers irlandais vont mettre en oeuvre des drones aériens et des mini sous-marins téléopérés | Newsletter navale | Scoop.it

The Naval Service will more than halve the age of its eight-vessel fleet when the third ship in a €162m order is delivered by 2016.

The news came as the Navy's second new vessel, LE James Joyce, is now concluding sea trials and will be delivered within weeks for commissioning in May.

A sister ship to the LE Samuel Beckett which was delivered last year, LE James Joyce was built at Babcock Marine's shipyard in north Devon.

A third vessel, the order for which was confirmed by Taoiseach Enda Kenny, is now under construction and is scheduled for a late 2016 delivery.

The delivery of the as-yet-unnamed third offshore patrol vessel will dramatically reduce the age profile of the navy's Haulbowline-based fleet.

Literary

The vessel, like its sister ships, is expected to be named after an Irish literary figure.

The third new vessel will see five of the navy's main patrol vessels having entered the fleet since 1999.

At a cost of €54m each, the new vessels are the most hi-tech ever operated by the Naval Service and are capable of handling advanced technology such as drones and robotic submarines.

The LE Samuel Beckett replaced the 35-year-old LE Emer which was sold at auction in October 2013 to an African consortium.

The LE James Joyce will replace the LE Aoife (1979) which was decommissioned last January and has now been donated to the Maltese navy.

Each of the new ships are developments of the original design chosen for the LE Roisin/LE Niamh in 1997.

Naval Service officials confirmed that the new ships will dramatically increase the technological capacity of the Navy both in terms of surveillance and incident response times.

The ability to operate drones, which are already used by the Defence Forces, will also dramatically increase the navy's patrol and surveillance capabilities.

Each ship can similarly operate remotely controlled mini- submarines.

The new vessels are 12m bigger at 90m in overall length than the old LE Roisin/Niamh design. With a top speed of 23 knots, the new ships will also be over 30pc faster than the ageing vessels they replace.

The Government has insisted the deal represented exceptional value for money with shipyards offering cut-price contracts as they battle for orders.

obsolete

Defence minister Simon Coveney warned that Ireland cannot afford to revert to the "bad old days" of the 1940s and '50s when the Naval Service was totally reliant on a fleet of ageing and obsolete former Royal Navy corvettes. It is expected that the third new ship will replace LE Aisling (1980), which will have seen 36 years of service.

When all three are commissioned, the oldest ship in service will then be the LE Eithne (1984).

LE Eithne will also be the only remaining vessel in the fleet which was built in Ireland.

The three craft are the first new ships commissioned for the Naval Service since the LE Roisin (1999) and LE Niamh (2001) which displace 1,500 tonnes.

Le Kazakhstan (société Gidropribor) et la France (société ECA) vont coopérer pour la réalisation de drones sous-marins (UUV)

Le Kazakhstan (société Gidropribor) et la France (société ECA) vont coopérer pour la réalisation de drones sous-marins (UUV) | Newsletter navale | Scoop.it

Kazakhstan and France are to work together on unmanned underwater vehicles (UUVs), Kazakh national defence company Kazakhstan Engineering revealed on its website on 16 February.The company's Gidropribor subsidiary will be co-operating with French firm ECA Robotics in the field of UUVs. The agreement will see the Kazakhstan Navy procure 10 UUVs for use on survey work in the Caspian Sea, as well as for finding and destroying objects on the sea floor.Under the agreement signed by ECA Robotics and Gidropribor, the Kazakh firm will undertake local assembly of the platforms as part of the procurement contract, which will last through to 2017. As a result, the firm will be able to increase its workforce by 10 to 15%.Furthermore, ECA Robotics will work with Gidropribor to export UUVs and similar remotely operated vehicles to other countries in the region and in Asia. 

 

COMMENTThe move by ECA Robotics into the Kazakh market comes at a time when French defence companies may be looking to move away from the Kazakh and Central Asian market.Previously established joint ventures between Kazakhstan Engineering and Airbus Helicopters (formerly Eurocopter) and Thales are under evaluation. The Kazakh government revealed in March 2014 that it was allocating KZT10 billion (then USD54 million) to purchase the Airbus Helicopters 50% stake in the Eurocopter Kazakhstan Engineering joint venture. The Kazakh government is also selling its 50% stake in the Thales Kazakhstan Engineering joint venture, with tenders closing for a second time on the loss-making enterprise in February 2014. However, Thales' future strategy for the joint venture is unclear.Additionally, the company is limited in its customer base for the Caspian Sea, with Russia and Iran both under international sanctions. French firms have begun to make inroads into the Turkmenistani energy market, but the country's main infrastructure is geared towards onshore field development and overland pipeline transport.

U.S. Navy : la LCS-2 USS Independence effectue l'évaluation opérationnelle du Mission Package "guerre des mines"

U.S. Navy : la LCS-2 USS Independence effectue l'évaluation opérationnelle du  Mission Package "guerre des mines" | Newsletter navale | Scoop.it
USS Independence (LCS 2 ) departed San Diego Jan. 30 for Naval Air Station Pensacola, Fla., to conduct operational evaluation and testing of the mine countermeasures mission package.
Independence, the lead ship of the Independence variant of the littoral combat ship, will sail through the U.S. 4th Fleet area of responsibility, transiting the Panama Canal and making a port visit to Cartagena, Columbia.
Cmdr. Michael Smith, commanding officer of LCS Crew 201, the Spartans, credited the ship's "superb state of readiness" to the professionalism of the men and women in the LCS community.
"It's a true testament to the tremendous skill, determination and teamwork of her crews, the Spartans and LCS Crew 202, the Rattlesnakes, as well as the Sailors and civilians of Littoral Combat Ship Squadron (LCSRON) 1," Smith said. "Each member of the team worked diligently to ensure we departed San Diego ready for the transit and, more importantly, to arrive in Pensacola prepared to execute MCM mission package testing so critical to our Navy's mission."
Testing includes grooming the system for the remote multi-mission vehicle, and initial operational test and evaluation (IOT&E) of the mine countermeasure mission package integrated work-ups. IOT&E is the event that will transition the mission package from testing to fleet use.
The ship is expected to return to San Diego later this year.
LCS 2 is a trimaran-hulled small surface combatant built for high speed, which can conduct agile and mission-focused operations in the complex littoral environment. Built by Austal USA, the Independence variant of LCS can be rapidly reconfigured with specific Mission Modules to conduct Surface Warfare, Mine Countermeasures and Anti-submarine warfare.

L'Inde veut à présent construire ses batiments de guerre des mines au chantier GSL avec un partenaire étranger

L'Inde veut à présent construire ses batiments de guerre des mines au chantier GSL avec un partenaire étranger | Newsletter navale | Scoop.it

NEW DELHI: India is all set to scrap the long-pending deal for South Korean mine countermeasure vessels (MCMVs), which are highly-specialized smallish warships that detect, track and destroy enemy mines to keep shipping traffic safe, due to allegations of agents having vitiated the entire selection process.
Instead, in recognition of Navy's critical operational requirement for MCMVs, the defence ministry will "nominate" defence PSU Goa Shipyard (GSL) to build eight such specialized vessels with foreign collaboration through a fresh tender soon.
With defence minister Manohar Parrikar on Sunday returning to New Delhi from Goa, where he visited GSL and held talks with top officials, sources said the final decision to scrap the original MCMV tender is "likely in the next few days".
It was under the UPA-2 regime that the final price negotiations with South Korean company Kangnam Corporation had concluded in October 2011. Under it, two MCMVs and transfer of technology were to be acquired from Kangnam in a deal worth Rs 2,700 crore, with Goa Shipyard building another six such vessels for over Rs 6,000 crore.
The inking of the deal, however, was kept on hold due to the allegations swirling around it. Now, attorney general Mukul Rohatgi has recommended scrapping of the entire selection process for the MCMVs, which began way back in July 2005, since Kangnam hired agents to facilitate the deal. The MoD has already "encashed" the Rs 3 crore bank guarantee furnished by Kangnam under the pre-contract "integrity pact", as was earlier reported by TOI.
"Under the new tender or RFP (request for proposal), all the eight MCMVs will now be built in India by GSL. The defence shipyard will tie up with a foreign collaborator, which can include Kangnam since it's not being blacklisted," said a source.
The Navy has repeatedly sounded alarm over delays in the acquisition of MCMVs, down as it is to just seven ageing Karwar and Pondicherry-class of minesweepers for both the east and west coasts when it needs 24 to be comfortable. They have become all the more important due to the increasing forays of Chinese submarines, which can easily lay mines, into the Indian Ocean region.
Just last week, Navy chief Admiral Robin Dhowan again stressed the "urgent need" for MCMVs. "They are required to keep our harbours open and safe in the event of hostilities. The government has to take a decision since our force-levels of minesweepers/mine-hunters has gone down drastically," he said.
Underwater mines, which are cheap and relatively easy to plant, can create havoc by choking up harbours. The around 1,000-tonne MCMVs are used to "clear" harbour approaches or departure routes as well as offshore installations for shipping activity. With high-definition sonars, acoustic and magnetic sweeps, these specialised vessels can detect marooned and drifting mines. They then use remote-controlled systems like small underwater vehicles to then detonate the mines at safe distances.

ndia's Ministry of Defence (MoD) is poised to scrap the INR23 billion (USD383.33 million) acquisition of eight mine countermeasure vessels (MCMV) from South Korean firm Kangnam Corporation following allegations of wrongdoing in the tender process.

Instead, the MoD plans to locally build the eight MCMVs at the state-owned Goa Shipyard Limited (GSL) with overseas help.Indian Navy (IN) sources said new Defence Minister Manohar Parrikar is expected to terminate the MCMV tender on the recommendation of Attorney General Mukul Rohatgi after an internal investigation concluded that Kangnam had contravened the MoD's Integrity Pact by employing agents to secure the deal.Kangnam, which was selected over Italy's Intermarine Shipyard, denies any malpractice. The pact specifies that no agents or middlemen can be employed by the vendor to obtain the contract. It also stipulates that even after completion all deals can be terminated if the pact is contravened.In May, after the internal inquiry was concluded, the MoD cashed Kangnam's INR30 million bank guarantee, furnished along with its MCMV bid submitted in 2008-09.Derivatives of the Yang Yang class (itself a modification of the Ganggyeong or Swallow class) in service with the Republic of Korea Navy (RoKN), the MCMVs were to be built of composite material and high-grade steel to ensure minimal magnetivity. They were also to be equipped with high-definition sonars and acoustic and magnetic sweeps to detect underwater mines, along with underwater vehicles to detonate them. The IN has been pressuring the MoD against cancelling the tender, negotiations for which concluded in October 2011, on the grounds that its MCMV requirement was "operationally critical". On 14 November IN chief of staff Admiral R K Dhowan reiterated the "urgent need" for modern MCMVs to counter growing threats in the region."The government has to take a decision since our force levels of minesweepers and mine hunters has dropped drastically," he said during a four-day visit to India by French Navy chief Admiral Bernard Rogel that ended on 17 November.The navy wants to replace its six ageing Karwar-class (also known as Pondicherry-class) minesweepers, built locally as modified versions of the Soviet Natya I-class vessels and commissioned between 1986 and 1988. Under the MCMV contract, Kangnam's Busan shipyard was to construct two of the 800-ton vessels, while GSL would build the remaining six under a technology transfer. GSL aims to further build another 16 additional minesweepers for around INR160 billion.IN officials, meanwhile, told IHS Jane's that the tender to locally construct the eight MCMVs would be dispatched around the end of 2015 and the platforms would be constructed within six to seven years of the deal being signed. They added that Kangnam could participate as it had not been blacklisted by the MoD.

L'US Navy et Northrop Grumman vont déployer plus d'USV guerre des mines en opérations dans le Golfe en 2015

L'US Navy et Northrop Grumman vont déployer plus d'USV guerre des mines en opérations dans le Golfe en 2015 | Newsletter navale | Scoop.it

After successfully demonstrating real-world operations of a prototype unmanned mine-hunting system in the Gulf, Northrop Grumman Corporation is preparing to deploy two more of the units with the US Navy's (USN's) Gulf-based 5th Fleet in early 2015, officials told IHS Jane'son 9 October.

The Mine Hunting Unmanned Surface Vehicle (MHU), which comprises a remotely operated, navy-standard, 11 m rigid hull inflatable boat (RHIB) towing Northrop Grumman's AQS-24A mine-detecting sonar, was developed jointly by the company and the USN. In early 2014, a prototype was deployed to the Gulf to enable the development of tactics, concepts of operation, and design requirements for a future programme of record tied to the USN's Littoral Combat Ship.

The AQS-24A is the programme of record for the USN's anti-mine warfare helicopter squadrons. The MHU technology was first adapted from that helicopter-towed system in the late 1990s. It was then tailored for operations from small boat platforms and later transitioned to unmanned surface vehicle (USV) operations.

"On the helicopter, you have operators that control the system and do the object detection real-time [from] the helicopter. On the unmanned surface vessel, it's much more remote. We tow the system in the same way that the helicopter does, but we format the data on the USV and transmit it via radio back to a shore- or ship-based command-and-control van, where operators do the mine calls. The operator controls the platform via that radio link from that command-and-control van as well."

As the system can be operated both day and night, around-the-clock sweeping is feasible - unlike with the helicopter-borne system, added Cumm.

Inside the command-and-control van, two consoles allow for two operators to control the MHU. One operator controls the USV via a series of cameras and radars onboard the 11 m platform. The other monitors the sonar data and controls the AQS-24A vehicle. Up to two MHUs can be operated simultaneously.

For the Gulf demonstration, only one MHU was employed. The system was launched from a commercial shipping port in Bahrain. "It transited out into the shipping lanes and conducted a remote-controlled search from the mouth of the harbour, demonstrating the utility in harbour protection and undersea object detection and classification, which is very important in that part of the world," said Cumm.

A number of partners throughout the Gulf region and in the Asia-Pacific region, as well as NATO countries, are interested in the technology and capability, said Cumm, although he declined to identify the potential customers.

"Mine warfare has become a global activity. It's not just the US Navy or the [UK] Royal Navy; it's navies working together," said Cumm.

L'US Navy déploie son nouveau système de détection de mines par laser héliporté sur MH60S (ALMDS) pour la 1ère fois

L'US Navy déploie son nouveau système de détection de mines par laser héliporté sur MH60S (ALMDS) pour la 1ère fois | Newsletter navale | Scoop.it

The U.S. Navy has forward deployed the Airborne Laser Mine Detection System (ALMDS) to the 5th Fleet area of responsibility (AOR). ALMDS is a sensor system designed to detect, classify and localize floating and near-surface moored mines. Operated from the MH-60S helicopter, ALMDS provides rapid wide-area reconnaissance and assessment of mine threats in littoral zones, confined straits, and choke points.

Sailors from Helicopter Sea Combat Squadron (HSC) 26, Detachment 2, Laser Hawks, began the operational testing and demonstration of ALMDS in 5th Fleet on the system's maiden deployment August 4.

"The U.S. Fifth Fleet is focused on reducing the threat posed by sea-based mines in the region should that be necessary and the presence of ALMDS here in the theater adds to our capacity to do just that," said Vice Adm. John W. Miller, commander, U.S. Naval Forces Central Command, U.S. 5th Fleet, Combined Maritime Forces. "The international community has a critical shared interest in the free flow of commerce in this region. ALMDS, along with the many other counter-mine systems we operate in the Fifth Fleet allows the Navy to keep the sea lanes open."

"It's a laser-driven system that works like radar," said Lt. Cmdr. Theodore Lemerande, officer in charge of Laser Hawks. "It beams a laser down into the water and picks up reflections from anything it bounces off of. The system then registers the returned information and uses that data to produce a video image in order for technicians on the ground to determine what the object is."

The Navy's largest helicopter, the MH-53E Sea Dragon, has been a critical component of the Navy's ability to perform the airborne countermine mission in the Fifth Fleet and elsewhere for many years. ALMDS expands the countermine mission to smaller MH-60S helicopters.

"MH-60Ss have traditionally been a platform for anti-surface warfare, combat support, humanitarian disaster relief, combat search and rescue, aero-medical evacuation, and special warfare," said Lemerande. "ALMDS allows us to take airborne mine countermeasures technology to these smaller helicopters that can fly from smaller ships allowing us to take mine countermeasures into places that may not have been accessible before."

L'US Navy teste un nouveau véhicule sous-marin autonome multimissions ayant la forme d'un thon robotisé

L'US Navy teste un nouveau véhicule sous-marin autonome multimissions ayant la forme d'un thon robotisé | Newsletter navale | Scoop.it

Norfolk, Va. —- The Navy is testing a stealthy, 4 foot-long fish-shaped autonomous underwater vehicle designed to blend in with undersea life and perform combat sensor functions, service officials explained.

The so-called “bio-memetic” undersea vehicle is currently being developed as part of the Chief of Naval Operations Rapid Innovation Cell,  or CRIC – a special unit set up by CNO Adm. Jonathan Greenert in 2012 to explore the feasibility of rapidly turning around commercially available technologies for Naval military use.

“It mimics a fish. It looks like a fish. We call it robo-tuna, affectionately, but it is a UUV (unmanned undersea vehicle).  It does not have a propeller or a jet. It actually swims by flipping its tail around,” said Capt. Jim Loper, concepts and innovation department head, Navy Warfare Development Command, Norfolk.

The robot-fish is highly maneuverable and can accelerate quickly, reaching speeds up to 40 knots, Loper said. Being propelled by its tail instead of a shaft or propeller helps it remain stealthy and energy efficient. The shark-like sensor is engineered to carry a range of payloads from acoustic sensors to underwater cameras, he explained.

Built in Massachusetts by a firm called Boston Engineering, the robot fish could be used for a range of missions including undersea mine detection or prolonged surveillance of ships, ports and submarines.

“We’re imaging this can loiter for days, possibly weeks on a battery that allows it to maintain its position. This is a sensor we can put out there that matches in with the local life so to speak,” Loper added.

The UUV is currently configured with a lithium ion battery and is engineered so that its front end remains stationary in order to maximize sensor performance.

L'US Navy teste un nouveau radar et les roquettes APKWS sur un hélidrone MQ-8B Firescout pour les LCS

L'US Navy teste un nouveau radar et les roquettes APKWS sur un hélidrone MQ-8B Firescout pour les LCS | Newsletter navale | Scoop.it

The Navy is adding weapons and a new maritime search radar to Fire Scout drone, a helicopter-like vertical take-off UAS now conducting tests aboard the Littoral Combat Ship, service officials said.

The weapons being added to the Fire Scout are part of a program that fires laser-guided 2.75 inch, folding-fin rockets called Advanced Kill Precision Weapons System, or APKWS. Using laser guidance to paint and pinpoint targets for the Fire Scout, APKWS was able to conduct successful land-based test firings, said Capt. Patrick Smith, program manager for multi-mission tactical unmanned air systems.

“We’ve demonstrated an ability to designate and shoot APKWS from Fire Scout. The next-step is ship based testing,” Smith said.

Ship testing, however, is on hold due to ship availability, Navy officials said.

The live-fire testing for APKWS and Fire Scout took place at Naval Air Weapons Station China Lake, Calif. The Navy is considering having the Fire Scout MQ-8B fire APKWS rockets over the sea sometime in the future, he added.

In fact, while over-the-sea APKWS testing is uncertain for the MQ-8B, the Navy is planning to test APKWS on its newer, larger variant of the Fire Scout, the MQ-8C, in 2015, service officials said.

Meanwhile, a new radar, slated to deploy on the Fire Scout aboard the USS Fort Worth (LCS 3) in 2015, will greatly extend the intelligence, surveillance and reconnaissance, or ISR, range of the aircraft, Smith explained.

The existing electro-optical and infrared cameras on the Fire Scout have a range of six-to-ten miles, whereas the new maritime radar will be able to find targets at ranges out to 80 nautical miles, Smith said.

The radar, which can bring a ten-fold increase in surveillance range to the ship, is a commercial product built by a firm called Telephonics, Smith said.

The Navy is currently testing the radar on the MQ-8B Fire Scout at Patuxent River Naval Air Station, Md.

“The maritime search radar is not oriented specifically toward ASW (anti-submarine warfare) but it does have capability against smaller targets,” Smith said.

The Fire Scout is also slated to receive a new mine-detection sensor for littoral waters by 2017 called the Coastal Battlefield Reconnaissance and Analysis, or COBRA, Smith said.

Detecting mines with the Fire Scout in order to keep the LCS and its crew at a safe distance is COBRA’s primary function, however it will also be able to detect submarines near the surface, Smith said.

La Royal Navy teste un chasseur de mines téléopérable pouvant déployer des véhicules autonomes sous-marins

La Royal Navy teste un chasseur de mines téléopérable pouvant déployer des véhicules autonomes sous-marins | Newsletter navale | Scoop.it

The motorboat, called Hazard, is currently being put through its paces by a specialist team of sailors in Portsmouth naval base. The boat can also act as the ‘mother ship’ to an assortment of hi-tech remote-controlled and robot submersibles.

Collectively, they can search for, hunt and finally destroy mines faster than the Royal Navy’s Sandown and Hunt-class ships, and they also have the added benefit of keeping the sailors required to operate them out of harm’s way.

Modified versions of the same systems are also being looked at to carry out survey operations such as those performed by HMS Echo, currently looking for the missing Malaysian airliner, as part of the future mine-countermeasures and hydrographic capability programme.

The Maritime Autonomous System Trials Team (MASTT) is the small Portsmouth-based Royal Navy unit testing the new unmanned systems.

Lieutenant Commander Jack McWilliams, the officer in command of MASTT, said:

"This will be the seafaring equivalent of the unmanned aircraft which have revolutionised aerial warfare.

"It takes the sailor out of the minefield, but we are not taking them out of the equation. You will still need individuals with specialist mine warfare and hydrographic skills, a human being to identify a contact, but they will be much safer, and this is a much more effective way of doing our job.

"This technology is fantastic, and we are right at the forefront of it. It is the future."

The family of equipment MASTT is putting through its paces is headed by Hazard, a small, fast motor launch, capable of speeds up to 30 knots and able to be transported by an RAF Hercules.

The boat carries either the bright yellow, torpedo-sized Remus 600 or the much smaller Remus 100, which are sent off to scan the seabed at depths of up to 600 or 100 metres respectively.

After several hours in the water scanning the ocean floor, the submersibles return to their mother ships and the data is then collected downloaded and analysed by the Royal Navy’s mine warfare experts.

They can then send in another small submersible, steered onto a suspect object and identified by a mine specialist using its onboard camera. On the front line it would carry an explosive charge to destroy any mines; like the Seafox system used by Royal Navy minehunters off Libya and in the Gulf.

The immediate goal for the team is to fit this technology and unmanned sweep systems to a Hunt-class ship, but in the future the system could easily be run from any reasonable-sized warship, and sent anywhere in the world in just 48 hours.

The remote controlled system will be tested more widely by the Royal Navy before the end of the year.
