Canada : le projet d'achat de 28 hélicoptères navals Cyclone de Sikorsky semble relancé

Canada : le projet d'achat de 28 hélicoptères navals Cyclone de Sikorsky semble relancé | Newsletter navale | Scoop.it

OTTAWA - The Harper government appears to have cooled on the idea of scrapping the purchase of the air force's CH-148 Cyclone helicopters and is back in talks with the manufacturer to salvage the troubled $5.7-billion program.

The plan to acquire 28 maritime choppers to replace Canada's 50-year-old CH-124 Sea Kings — which fly from the decks of Canadian warships — is years behind schedule, billions of dollars over the anticipated budget, and apparently beset with technical glitches.

Earlier this fall, the Department of Public Works indicated it was looking at other aircraft because Cyclone manufacturer Sikorsky had only delivered four test aircraft, which National Defence has refused to formally accept.

Louis Chenevert, the chairman of United Technologies Corp., the owners of Sikorsky, told analysts in a conference call on Thursday that the company is having "productive discussions with the Canadian government" on the Cyclone program and that the talks are in the "advanced stages."

Public Works Minister Diane Finley conceded the government "is in discussions" with Sikorsky to see if they can put together a plan to go forward.

Precisely what that entails, however, remains unclear.

"We are working. We had a third party come together and put a report together," Finley said Friday at an event to announce the purchase of hard-top military shelters.

Last spring, Finley's predecessor, Rona Ambrose, asked for an independent analysis of whether Sikorsky could deliver what it promised, and Finley says those recommendations are guiding the discussions.

The report suggested the government had 90 days from when it received the analysis to salvage the program, which was criticized by the auditor general a few years ago for being misrepresented as an off-the-shelf purchase rather than a development contract.

Finley's officials asked Sikorsky's rivals in October for detailed information, pricing, and potential delivery dates should the Conservative government cancel the existing contract.

AgustaWestland, which is marketing its HM-1 Merlin helicopter, and NH Industries, representing Eurocopter and the NH-90 chopper, both responded. Sikorsky was also asked for information about its other maritime helicopter, the MH-60 Sea Hawk, which is in service with the U.S. Navy.

Chenevert, however, said Thursday that his company intends to deliver eight helicopters this year, followed by eight more each in 2014 and 2015.

"The airplane is flying, people are training," said Chenevert, who offered up photos of the training effort, which is taking place at a military base in Shearwater, N.S.

"Obviously, it is binary. I mean, if everything gets resolved, eight get delivered; if not, they move into next year and we know exactly what the math will be, but at this point in time, we're planning eight, eight, and eight."

Throughout most of 2013, the government and Sikorsky have been engaged in a public tug-of-war over when a final version of the helicopter would be ready for service, despite two contract extensions and more money for engine improvements.

There have been ongoing technical concerns that prompted the air force's directorate of flight safety to issue a restricted flight certificate. Some of those worries involved whether the helicopter's sensitive electronics were sufficiently shielded to prevent electro-magnetic interference.

Internal documents viewed by The Canadian Press earlier this year revealed that air force evaluators warned nearly a decade ago that the Cyclone might not measure up in terms of engine performance, acoustic noise and its ability to resist electronic interference.

The purchase was nonetheless allowed to proceed.

Un think tank américain souligne le rôle vital de Gibraltar pour les opérations des sous-marins nucléaires de l'US Navy

Un think tank américain souligne le rôle vital de Gibraltar pour les opérations des sous-marins nucléaires de l'US Navy | Newsletter navale | Scoop.it

Gibraltar plays a ‘vital’ role for the US Navy’s submarine operations at a time of increased Russian naval activity, a US think tank said. The Heritage Foundation made the statement in its Index of US Military Strength 2015, a wide-ranging annual research project that assesses the ability of the United States Armed Forces.

The document notes that the US Navy keeps a number of submarines in the European region and that these contribute to the intelligence, surveillance and reconnaissance capacities of EURCOM, the US military’s Germany-based European Command.
Some of these submarines ‘frequently’ dock at the Z Berth in the naval base at Gibraltar, the Heritage Foundation said. “The US cannot dock nuclear powered submarines in Spain making access to Gibraltar’s Z berths vital,” the report added.
“Gibraltar is the best place in the Mediterranean to carry out repair work.” “Strong US–UK military cooperation assists the US in keeping submarine assets integrated into the European theatre.”
The Heritage Foundation cites retired US Navy Admiral James Stavridis, who in 2012 highlighted the importance of the US Navy’s European submarine operations against the backdrop of increased Russian naval activity. Since then, Russian ships have remained active in the Mediterranean and regularly sail through the Strait of Gibraltar, including calls at Ceuta for fuel.
“These [US submarine] capabilities are increasingly important as the Russian Federation Navy increases the pace, scope and sophistication of its submarine fleet,” Admiral Stavridis said.
The US Navy also has a fleet of P-3 Maritime Patrol Aircraft and EP-3 Reconnaissance Aircraft operating from US bases in Italy, Greece, Spain and Turkey. These aircraft complement the intelligence-gathering capabilities of US submarines.
In its regional assessment of the European operating environment, the Heritage Foundation also notes the strategic importance of the Strait of Gibraltar. At 40 miles long and 8 miles wide at its narrowest point, the strait is one of the world’s most important maritime choke points.
“More than 200 cargo vessels pass through the Strait of Gibraltar every day carrying cargoes between Asia, Europe, Africa, and the Americas,” the report notes.
“Its proximity to North Africa, combined with the narrowness of the strait, has presented security challenges for US and allied warships.”
The report notes the importance of the US military’s presence in southern Europe, particularly at a time of mounting instability across much of North Africa.
It highlights the role of US naval bases in Europe including the Naval Air Station in Sigonella, Italy; the Naval Support Activity Base in Souda Bay, Greece; and the Naval Station at Rota, Spain.
Naval Station Rota will be home to four destroyers equipped with the Aegis ballistic missile air defense system. In addition, the USS Mount Whitney, a Blue Ridge-class command ship, is permanently based in the region. This ship provides a key command-and-control platform, which was successfully employed during the early days of the recent Libyan operation.

Propulsion du futur destroyer russe : ce sera le nucléaire - Le portail des forces navales de la Fédération de Russie

Propulsion du futur destroyer russe : ce sera le nucléaire - Le portail des forces navales de la Fédération de Russie | Newsletter navale | Scoop.it

C'est en tout cas ce qu'a annoncé le commandant en chef de la marine russe, l'amiral Viktor Tchirkov, à l'occasion de la mise sur cale de deux nouvelles corvettes au chantier naval du Nord (Saint-Pétersbourg) le 20 février dernier.

 

Par ces déclarations, le commandant en chef de la marine russe semble clore un débat qui durait depuis la fin des années 2000 sur la nature de la propulsion du futur destroyer : turbine à gaz ou nucléaire. La rupture de la coopération militaro-technique avec l'Ukraine, dans le contexte de la crise qui dure depuis fin 2013, a dû influencer la prise de cette décision. La Russie recevait en effet ses turbines à gaz de l'entreprise ukrainienne Zorya Machproject située à Nikolaïev. Les turbines ukrainiennes équipent en effet les premières unités des frégates russes des projets 11356M et 22350, mais suite à la rupture de la coopération avec Kiev, Moscou va devoir se tourner vers des fournisseurs indigènes, et c'est l’entreprise Saturn (Rybinsk) qui pourrait fournir les prochaines turbines à gaz. La Russie n'a plus mis sur cale de bâtiment à propulsion nucléaire depuis le croiseur atomique Pierre le Grand (Projet 1144, ex Youri Andropov) mis sur cale en 1986 à l'usine de la Baltique (St Pétersbourg).

L'annonce, faite au chantier naval du Nord, semble en outre confirmer que c'est ce chantier qui sera en charge de la construction du bâtiment dont la première unité pourrait être mise sur cale dès 2017, selon une source au sein du complexe militaro-industriel russe. Rappelons que le programme d'armement 2011-2020 ne comporte pas de budget dédié à la construction du futur destroyer, mais qu'en revanche, les fonds pour la phase d'avant-projet et d'étude ont bien été budgetés. Le programme d'armement 2016-2025 devrait quant à lui comporter le budget pour la constructions de plusieurs unités : l'idée, très ambitieuse, est de disposer à l'horizon 2025 de 12 unités, dont 6 dans la flotte du Nord et 6 dans la flotte du Pacifique.

Sur le design du bâtiment, il semblerait que ce soit l'institut Krilov qui ait remporté la mise sur le bureau Severnoe. Le 'Lider' déplacerait 14 000 tonnes pour 185 mètres de long et 22 mètres de large (donc équivalent de point de vue là au destroyer américain de type Zumwalt), et comme le montre les photos ci-après, de 6 complexe universels de tirs pour navire UKSK (pour les missiles de type Kalibr et Onyx notamment) et 12 VLS (système de lancement vertical) situés tous deux à l'avant, tandis qu'à arrière se situent encore 2 VLS, près de la plateforme pour hélicoptères. Krilov semble ainsi avoir revue sa copie depuis la visite que Vladimir Poutine avait réalisé dans les locaux du bureau d'étude en 2009 au cours de laquelle une maquette lui avait été présentée.

Ces déclarations prouvent que malgré les difficultés économiques, la Russie affiche toujours autant de détermination à vouloir assumer un statut de puissance navale. Au-delà du double défi technique que représente la construction d'un bâtiment de 14 000 tonnes à propulsion nucléaire, avec l'intégration de systèmes de navigation et de combat (cf. sérieuses difficultés d'intégration déjà rencontrées sur les frégates du projet 22350), il se pose également la question du budget. Combien coûte une unité ? L'objectif de 12 unités est-il réaliste d'un point de vue financier (ne parlons pas du calendrier qui est incantatoire) ? En période de difficultés économiques, si des coupes budgétaires sont à prévoir dans la marine, il est fort probable que les programmes de grands bâtiments de surface soient les premiers touchés.

Marine russe : les travaux de refonte-modernisation du SNA Carp (Sierra I - Projet 945) arrêtés au chantier Zvezdochka faute de financement

Marine russe : les travaux de refonte-modernisation du SNA Carp (Sierra I - Projet 945) arrêtés au chantier Zvezdochka faute de financement | Newsletter navale | Scoop.it

At shipbuilding plant "Zvezdochka" repair work on the Carp B-239 submarine stopped. Perhaps, because of financing reduction.

As told to the correspondent of FlotProm two sources at the enterprise and a source in the company contractor, all repair work on the head submarine of the Barracuda project 945 is curtailed now.
According to one of sources, the termination of financing of repair of the submarine can be a probable cause of a stop of works.

The contract for repair and modernization of submarines of the Carp project 945 B-239 and B-276 "Kostroma" was signed with the Severodvinsk ship-repair center "Zvezdochka" on May 14, 2014. The center of ship repair "Asterisk" had to carry out troubleshooting of boats, unload nuclear fuel, replace all electric equipment, carry out repair of mechanical parts. During modernization of "Barracuda" had to receive new hydroacoustic stations, fighting management information systems, a radar, GLONASS/GPS navigation systems and systems of arms. It was planned that will return to structure of Navy of Russia "Carp" in 2017.

The Carp B-239 submarine began the service in 1984 under the name K-239. I was a part of forces of constant readiness of Northern fleet. In 1990 it is declared by the best ship on fleet. In 1992 it is reclassified in ABPL and it is renamed into B-239. It is brought out of structure of fleet on May 30, 1998 and it is put on a trick in Severodvinsk. The second submarine of the Kostroma project 945 is put on April 21, 1984 at Red Sormovo plant in Gorky, floated on July 26, 1986, was a part of Northern fleet on December 30, 1987 under the name K-276. I had to pass modernization after a nuclear submarine "Carp". Submarines of projects 945 and 945A (B-336 "Pskov" and B-534 "Nizhny Novgorod") intended for fight against aircraft carriers and other submarines. Depth of immersion of boats makes 600 and 550 meters respectively. The ships of the project 945A are armed with six torpedo tubes of caliber 533 millimeters with a unit of fire of 36 torpedoes, and 945 - ─ two ─ caliber of 650 millimeters and four 533-millimetric (a unit of fire - 40 torpedoes).

Le bénéfice opérationel de Thales devrait augmenter en 2015 grâce au retour aux profits de sa filiale DCNS

Le bénéfice opérationel de Thales devrait augmenter en 2015 grâce au retour aux profits de sa filiale DCNS | Newsletter navale | Scoop.it

Le groupe français Thales a indiqué le 26 février que son bénéfice opérationnel devrait augmenter de 15% en 2015,  sous l'effet conjugué d'un retour aux profits de sa filiale DCNS et de ses économies. L'équipementier spécialisé dans l'aérospatiale, la défense et la sécurité précise également dans un communiqué anticiper pour cette année une légère progression de son chiffre d'affaires grâce à la hausse de près de 20% de ses prises de commandes en deux ans.

Thales s'attend à ce que ses prises de commandes se maintiennent à un "niveau élevé" en 2015, avec une croissance dans les pays émergents....

...Retour dans le vert pour DCNS

Thales a réalisé un chiffre d'affaires de 12,974 milliards d'euros, en hausse de 2% en données publiées, mais en recul de 1% sur une base organique, au-dessus du consensus Thomson Reuters I/B/E/S. qui s'établissait à 12,872 milliards. Son bénéfice opérationnel de 985 millions d'euros, en ligne avec les attentes, donnant une marge en recul de 0,4 point à 7,6%. En excluant la contribution du constructeur naval militaire DCNS, consolidé à hauteur de 35%, la marge opérationnelle de Thales ressort toutefois en hausse de 0,9 point à 8,5%.

DCNS a annoncé le 24 février qu'il comptait retrouver un bénéfice net en 2015 après une perte nette de 336 millions d'euros en 2014 entraînée par des provisions sur plusieurs contrats. Pour 2015, Thales table sur un bénéfice opérationnel de 1,130 milliard à 1,150 milliard d'euros, soit une hausse d'environ 15% au taux de change actuel.

Le groupe confirme aussi viser pour 2017/2018 une marge opérationnelle comprise entre 9,5% et 10%, accompagnée d'une hausse "modérée" de son chiffre d'affaires. L'action a clôturé en baisse de 0,44% à 51,55 euros le 25 février, donnant une capitalisation de 10,66 milliards. Elle a regagné 14,6% depuis le début de l'année après avoir perdu 3,9% en 2014.

L'US Navy pourrait avancer la date de début de construction des futurs SSGN Virginia Block V dotés de la tranche de lancement vertical VPM

L'US Navy pourrait avancer la date de début de construction des futurs SSGN Virginia Block V dotés de la tranche de lancement vertical VPM | Newsletter navale | Scoop.it

Washington – Navy officials have said they will consider moving up the date for the start of a new Virginia-class submarine program that would allow the boats to carry more firepower.

About 20 Virginia-class submarines, built jointly by Electric Boat in Groton and Newport News Shipbuilding in Virginia, would have their hulls lengthened by about 70 feet to accommodate the so-called Virginia Payload Module, allowing the subs to carry 28 more Tomahawk cruise missiles than the Virginia class subs under construction now.

Right now the Navy has planned construction of the first Virginia Payload Module for 2019. The new design is needed to provide more undersea strike capability as the Navy prepares to retire Ohio-class guided missile submarines in the mid-2020s.

At a hearing of the House Armed Services seapower subcommittee on the Navy’s budget Wednesday, Connecticut U.S. Rep. Joe Courtney, D-2nd District, asked if the schedule for the Virginia Payload Module could be moved up.

“I just wondered if you have any thought about possibly trying to accelerate that process?’” Courtney asked.

Sean J. Stackely, assistant secretary of the Navy in charge of acquisitions, said the Defense Department is already trying to determine if the Virginia Payload Module subs could be built sooner. He asked lawmakers to “give us a couple of months to come up with” a decision.

“The earlier we can do so, the better for our nation,” Stackley said.

Stackely said the Navy must determine how quickly the module's design could be completed and whether Electric Boat and Newport News Shipbuilding could begin building the boats earlier than planned.

Rep. Randy Forbes, R-Va., told Stackely, “We don’t have a couple of months" to wait for the Navy's decision because lawmakers are concerned about a "gap" in the Navy's firepower.

"If you can narrow that scope down, it would be very, very helpful to us,” Forbes said.

Stackely and other Navy officials also talked with lawmakers about the impact of across-the-the board spending cuts known as sequestration and other reductions in the Navy budget.

Vice Admiral Joseph Mulloy said the Navy’s budget has been cut by $25 billion over the last three years.

“We have the minimum necessary to be where it matters when it matters,” Mulloy said. “We are hanging on; we are making do.”

The Navy’s 2016 budget contains money to build two Virginia-class submarines. But that budget — and the rest of the proposed federal budget sent to Congress by the Obama administration last month — does not take into account the impact sequestration cuts, which are still in effect.

Most lawmakers, both Democrat and Republican, want to eliminate sequestration, across=the-board cuts established in the Budget Control Act of 2011 because lawmakers could not agree on a way to control spending. Partisan differences over spending priorities continue to foil all attempts to end sequestration.

IDEX 2015 : les nouveaux sonars de Thales pour petits bâtiments et Marines opérant en zones littorales

IDEX 2015 : les nouveaux sonars de Thales pour petits bâtiments et Marines opérant en zones littorales | Newsletter navale | Scoop.it

Thales has revealed details of a new anti-submarine warfare (ASW) sonar pairing specifically designed for small ship applications. Engineered to allow installation on offshore patrol vessels (OPVs) down to about 800 tonnes, the new CAPTAS-1 low-frequency variable-depth sonar and BlueWatcher hull-mounted sonar are intended to provide littoral navies with a credible ASW deterrent capability.

The CAPTAS family of low-frequency active/passive sonars was originally brought to market in the mid-1990s to meet growing demand for an improved surface ship ASW capability against quiet submarine threats. CAPTAS-1 builds on this pedigree, but shrinks the size to allow installation on small ships.

CAPTAS-1 uses a single - dependent tow for the active sonar source (a single free-flooded ring transducer operating at a centre frequency of about 1.5kHz) and a triplet receive array. Thales has also developed a compact and lightweight towed array handling system that uses a single automatic winch.

In July 2013, Thales (Stand B-030) conducted at-sea trials of a CAPTAS-1 engineering development model. According to figures released by the company, CAPTAS-1 will be able to operate at speeds of up to 12kts, and at depths down to 100m. Typical detection range is claimed to be in the region of 20-30km, depending on the target type and environmental conditions.

To enable installation on smaller OPVs, Thales has reduced deck footprint to 15m2 and weight to about 8 tonnes. One option is to install CAPTAS-1 in containerised form, with the sonar body/receive array and electrically powered towed array handling system housed in a standard 20ft shipping container; the winch control and electronic cabinets are installed in a 10ft container mounted adjacent.

Alongside CAPTAS-1, Thales is also introducing the BlueWatcher hull-mounted sonar, which repackages the transmitter and receive arrays from the FLASH airborne active dipping sonar to provide small ships with a compact, 360° multi-purpose sonar. Thales has engineered the BlueWatcher ‘wet end’ to fit in a cylindrical volume just 700mm in diameter and 600mm in height, limiting dome/draft requirements to 0.85m. Inboard components are limited to a single cabinet and the operator console.

Only a single hull penetration is required out to the array.

In active mode, used for ASW or collision/obstacle avoidance, BlueWatcher transmits on any one of three frequencies between 3-5kHz in FM (frequency modulation), CW (continuous wave) and combination pulse modes. In passive mode, the system can be used to detect small, fast surface craft. According to Thales, the implementation of adaptive beam-forming has delivered performance that is equivalent to an array twice the size. It also allows for installation on ‘noisy’ ships where there is no quietening or noise hygiene.

La marine espagnole inquiète face au “fiasco” du sous-marin S-80 (Le portail des sous-marins)

La marine espagnole inquiète face au “fiasco” du sous-marin S-80 (Le portail des sous-marins) | Newsletter navale | Scoop.it


Traduction : Le portail des sous-marins

http://www.corlobe.tk/spip.php?article37245

Un profond pessimisme s’est installé au sein de la marine espagnole à propos du projet de sous-marins S-80. Le programme ambitieux visait à doter la marine espagnole de sous-marins de dernière génération. Hélas, il a connu de nombreux revers, faisant apparaitre des doutes parmi les responsables à propos de son avenir. Au ce jour, certains estiment même que le programme devrait être repris depuis le début. Et, en attendant, de recourir à des sous-marins d’occasion.

Incertitude. C’est le terme que les commandants de la marine espagnole utilisent pour définir la situation dans laquelle se retrouve le futur de la force sous-marine espagnole. Les sous-marins de la classe Agosta vivent leurs dernières années, et les retards qu’a connu le programme S-80 menacent de laisser l’Espagne sans sous-marins.

Les responsables de la marine espagnole ont exprimé leurs craintes pour l’avenir, à l’horizon de la fin de la décennie, au cours de plusieurs réunions informelles qui se sont tenues au cours des derniers mois.

Lors de ces réunions, ils ont mis sur la table les retards continuels que connait le programme, depuis les célèbres erreurs commises lors de la phase de définition, qui ont entrainé un sur-poids, obligeant à allonger de 7 m les sous-marins, jusqu’aux problèmes rencontrés avec le système de propulsion anaérobie.

« Le projet est radicalement différent, de la façon dont il a été conçu à la celle dont il sera livré. Que ce soit au niveau des capacités techniques, des innovations ou du prix prévu, » assurent des sources militaires.

 Les problèmes du système de propulsion anaérobie

Le système de propulsion anaérobie qui équipera les sous-marins S-80 « sera beaucoup moins ambitieux pour l’autonomie qu’il apporte que ce qui était prévu au départ. Il devait permettre au sous-marin de rester en plongée jusqu’à 20 jours. Aujourd’hui, selon les ingénieurs qui travaillent dessus, il est pratiquement impossible d’atteindre ce chiffre, » assurent des sources militaires.

« Un sous-marin plus gros, avec moins d’autonomie et coutant entre 750 millions et 1 milliard € pièce, » concluent-ils. Un projet qui « coutera très cher à l’Espagne et qui repoussera tout pays qui aurait pu être intéressé. »

C’est pourquoi, parmi l’état-major de la marine espagnole, de plus en plus d’officiers soutiennent une autre option : suspendre la construction des sous-marins et reprendre à zéro la conception en évitant de nouveaux dépassements de budget et sans précipitation. Le problème, c’est le temps : d’ici la fin de la décennie, l’Espagne n’aura plus de sous-marins opérationnels.

 Sans sous-marin jusqu’à la mise en service du S-82

Les sous-marins de la classe Agosta qui sont encore opérationnels — Mistral, Galerna et Tramontana — ont subi des grands carénages au cours des dernières années afin de prolonger leur espérance de vie opérationnelle de 5 ans. Le Tramontona a été le dernier, et la marine espère qu’il lui sera rendu cette année.

Cependant, la marine a des doutes raisonnables sur ces prévisions. Certains jugent « trop optimiste » que ces sous-marins puissent rester opérationnels encore 5 ans.

« En 2016, nous n’aurons plus que 2 sous-marins après le désarmement du Galerna, le plus ancien. Et il nous faudra attendre jusqu’à 2020 avec le Tramontana et le Mistral, en tenant compte des entretiens et des réparations, et cela en supposant qu’ils puissent tenir 5 ans, » estiment les sources consultées au sein de la marine.

 Recourir à des sous-marins d’occasion

Selon le calendrier de Navantia, le constructeur des S-80, le premier exemplaire sera livré en 2020. Concrètement, il s’agira du S-82, baptisé Narciso de Monturiol. Mais si les Agosta ne « survivent » pas jusqu’à cette date, l’Espagne n’aurait plus de sous-marins.

Certains à l’état-major proposent donc que l’Espagne acquiert des sous-marins d’occasion, que ce soit par un achat ou une location, auprès d’autres marines.

« Certains pays se sont lancés dans la rénovation de leur flotte sous-marine, alors qu’ils connaissaient la prospérité. Maintenant qu’ils ne peuvent plus payer, ils cherchent une porte de sortie. Ce serait une bonne option pour ne pas attendre le S-80, l’eau jusqu’au cou, et pour ne pas courir plus de risques que surviennent d nouvelles erreurs, » assurent-ils.

 L’Australie ne veut déjà plus du S-80

Le dernier revers, survenu il y a seulement quelques jours, est le refus de l’Australie de retenir le S-80 dans la liste des candidats pour son projet de rénovation. Alors que le projet espagnol avait été inclus jusqu’à présent dans la liste, finalement, seuls les projets japonais, français et allemand ont été retenus.

Rester à la porte de l’appel d’offres lancé par le pays qui avait montré le plus d’intérêt pour le S-80 constitue un « important échec commercial » pour les chantiers navals espagnols, et par conséquent, pour la marine espagnole comme le reconnaissent les sources militaires.

Jusqu’à présent, il y avait l’espoir des éventuelles exportations sous-marins, de façon à ce que le cout total du projet et des recherches et développements nécessaires au développement d’un projet de cette ampleur ne repose pas uniquement sur l’Espagne, jusqu’à présent, le seul client, et probablement qui le restera.

La Russie va-t-elle lancer un programme de destroyer à propulsion nucléaire ?

La Russie va-t-elle lancer un programme de destroyer à propulsion nucléaire ? | Newsletter navale | Scoop.it

Russia's Navy is seeking to use nuclear power to fuel its new destroyer-class vessels, Navy Chief Admiral Viktor Chirkov was quoted by Interfax as saying at a press conference in St. Petersburg on Friday.

While the new warships are still in the design process, "the main priority is to [create] a nuclear-powered destroyer," the admiral said.    

Nuclear-powered destroyers remain a novel concept in naval technology. Nuclear reactors are typically reserved for vessels that remain at sea for extended periods of time, such as aircraft carriers and submarines.

Although destroyer-class vessels are not precluded from similar long-term deployments, they are usually powered by conventional petroleum fuels, which require them to stop at overseas naval bases to refuel.

But as Russia does not have any major naval refueling facilities beyond its shores, nuclear power is an attractive option for Moscow, which is keen to increase its global reach.

Russia's navy, once an oceangoing powerhouse, has been largely relegated to coastal defense and short-range patrols by years of post-Soviet neglect and decay.

Under President Vladimir Putin's ambitious rearmament program, though, the navy is looking to reverse its fortune with the construction of a brand-new fleet. Several submarines have already been built, and by 2050 Russia hopes to construct a completely new oceangoing surface fleet of destroyers, cruisers and perhaps even an aircraft carrier.

MBDA a démarré la qualification du système téléopéré d'autodéfense rapprochée SIMBAD-RC et va bientôt le livrer

MBDA a démarré la qualification du système téléopéré d'autodéfense rapprochée SIMBAD-RC et va bientôt le livrer | Newsletter navale | Scoop.it

European missile house MBDA has started qualification of its remotely controlled SIMBAD-RC ship self-defence system, and will begin production deliveries later this year.

Developed from the manually controlled SIMBAD (Système Integré de Mistral Bitube d’Auto-Défense) twin-launcher system already in service with the French Navy and more than 10 export customers, the new SIMBAD-RC variant is a private venture development intended to address market requirements for a lightweight, automated close-in defence capability against air and surface threats out to a maximum of 6.5km. MBDA is partnered by Rheinmetall’s Defence Electronics business in Bremen, which is responsible for the design and development of the SIMBAD-RC turret.

Configured with two ‘lock-on before launch’ Mistral infrared homing missiles, the basic SIMBAD-RC configuration comprises one or two lightweight, gyro-stabilised turrets equipped with a Sagem MATIS SP mid-waveband thermal camera and an optional wide field-of-view day camera. In addition, the system includes a dedicated compact terminal, known as SMU-RC, which can manage up to two turrets (interfacing with the ship’s combat system or surveillance sensors).

Whereas the legacy SIMBAD requires an operator to man the above-decks weapon mounting, SIMBAD-RC is controlled remotely from a compact below-deck SMU-RC firing terminal. A single operator can control two SIMBAD-RC launcher systems from this station. In addition, SIMBAD-RC can be slaved to the ship’s radar or electrical-optical system for early cueing.

Preliminary design activities for SIMBAD-RC were completed at the end of 2011. MBDA commenced the full-scale development phase at the beginning of 2012, with Rheinmetall being brought under contract for development of the production series turret. The first prototype SIMBAD-RC turret was delivered by Rheinmetall in June 2014, and is now undergoing qualification. Deliveries of series production units are scheduled to follow from mid-2015.

MBDA has to date signed two contracts for the SIMBAD-RC system: one order to equip patrol vessels (two turrets per vessel); and a second order for the self-defence of high-value support ships (four turrets per ship). While the company declines to identify either customer, it is understood that the two navies in question are Turkmenistan (to equip new P 1200 class patrol vessels) and Saudi Arabia (for retrofit to the Royal Saudi Naval Forces’ two Boraida class auxiliary replenishment ships).

Les dispositifs équipant les navires marchands pour lutter contre la piraterie maritime

Les dispositifs équipant les navires marchands pour lutter contre la piraterie maritime | Newsletter navale | Scoop.it

Armed guards

Estimates from the Maritime Security Centre Horn of Africa indicate that approximately 80% of vessels transiting the piracy high-risk area used armed guards at the height of the attacks. In 2013, with the lower incidence of piracy, 35-40% of ships still used armed guards in transit.

The cost of a 3-4 man team is between $28,500 and $38,000, but the hefty bill is well worth it – seeing arms on board is a big deterrent,  this story by the Economist says, as pirates are playing it safe by first scouting for guards, whereas previously they indiscriminately opened fire to intimidate crews into submission.

Security installations on ships

If the pirates can’t board the ship, then they can’t hijack it. So piracy spurred a buzz of security innovations, which made it all but impossible for pirates to board the ships.

It started with good old barbed/ razor wire and electric fencing, but the inventions quickly got really interesting.

1. Water cannons/ ‘Anti-Piracy Curtain’

A system of high-powered streams of water that can be aimed at pirates trying to board a ship, or aimed at their boats, flooding and destabilising them.

In one version trademarked the ‘Anti-Piracy Curtain’, water hoses are dangled off the sides of the vessel, and when water is sprayed through the high-pressure nozzle, the hoses jerk wildly back and forth, packing enough force to seriously injure anyone in the way.

Some inventors were even mulling the idea to mix chilli oil into the water hoses for an added punch.

2. Long Range Acoustic Device (LRAD)/ ‘Sound Cannon’

Shaped like a big, round loudspeaker, the LRAD can emit painfully loud sound frequencies that are enough to disorientate any approaching pirates. But the real ingenuity is in the fact that the LRAD concentrates the sound waves into a narrow beam, making it easy to direct the sound at a specific target, much like using a spotlight. It means that the ship crew can direct the offensive sound at the pirates, and spare their own ears.  

3. Lasers

Another deterrent in use is a  laser beam capable of providing a visual warning to pirates at distance of over 2 km, and at shorter distances the glare is intense enough to temporarily blind attackers so that they are unable to target their weapons effectively.

4. Boat trap

Because most pirates approach a ship on motor-propelled boats, floating a net just under the water surface on the sides of the ship traps and disables the motorboat propeller.

5. Lubricant foam

Slippery foam or anti-traction material is a non-lethal substance which can be used to make the deck or sides of a ship slippery to avoid pirates from climbing it. The highly viscous substance substantially reduces traction of anything that comes in contact with it, making it difficult to walk or stand.

6. ‘Pain Ray’

The ‘Pain Ray’ - it’s official name is Active Denial System (ADS) - is a non-lethal weapon which transmits a narrow beam of electromagnetic energy to heat the skin without causing permanent damage. The wave penetrates beneath the skin which causes unbearable burning sensation, forcing pirates to run away or jump overboard.

7. ‘Guardian Anti-Piracy Barriers’

Perhaps the simplest and most ingenious invention is Guardian Anti-Piracy Barriers, a smooth, P-shaped casing of hard plastic that fits over the rail of any ship and prevents ladders and grappling hooks from getting a hold on the sides of the vessel.

It solves the fundamental problem of barbed/razor wire, which is its inherent danger to the crew itself – clothes get trapped in it and it’s easy to get nicked, and it’s cumbersome because has to be removed when the ship is entering port.

The inventors of barriers– a husband-and-wife duo from Britain –  called in the Royal Marines to test the  design, and after two hours of trying to latch on, the Marines gave up, and the design was declared a success.

IDEX 2015: la société chinoise CSTC présente un nouveau concept de TCD plus petit qu'un Type 071 et taillé pour l'export

IDEX 2015: la société chinoise CSTC présente un nouveau concept de TCD plus petit qu'un Type 071 et taillé pour l'export | Newsletter navale | Scoop.it

The China Shipbuilding and Trading Company (CSTC) used the IDEX show in Abu Dhabi to reveal a model of a new landing platform dock (LPD) that it could build for export.

A CSTC official told IHS Jane's that the concept was not developed to meet any current customer requirement, but was done to "show we have these capabilities".

The CSTC official could not confirm reports that China had offered a version of its Type 071 LPD in 2006 to meet a Malaysian requirement, but did not discount them.

CSTC's export LPD concept appears to be slightly smaller than the Type 071, the fourth of which was launched for the Chinese navy on 22 January. The model's vehicle and well deck contained 18 main battle tanks and 16 smaller utility vehicles.

Its hangar appears to hold two helicopters the size of the Changhe Z-8. Defensive armament included a 76 mm gun on the foredeck and two automatic cannon.

Italie : une campagne de recrutement pour la Marine en...anglais provoque la colère du public et des politiciens du pays

Italie : une campagne de recrutement pour la Marine en...anglais provoque la colère du public et des politiciens du pays | Newsletter navale | Scoop.it

It gave the world the linguistic sophistication of Latin and the poetry of Dante, but Italy has had its pride dented by the increasing use of English in prominent publicity campaigns.

Conservative politicians and commentators are indignant that the Italian navy – or Marina Militare – has adopted as its latest recruiting slogan “Be Cool, join the Navy”, using English rather than Italian.

The phrase appears on posters and billboards in a new recruitment campaign, along with images of Italian warships ploughing through the waves and commandos equipped as underwater frogmen.

Fabio Rampelli, an MP with the Right-wing Fratelli d’Italia (Brothers of Italy) party, said the use of English was unpatriotic and unacceptable.

“I ask myself how it came into the mind of the Italian navy to launch, with our money, a campaign in the English language to recruit young people,” he told parliament.

Basilio Catanoso, an MP from Silvio Berlusconi’s centre-Right Forza Italia party, said “it provokes anger, disgust and sadness to see the Marina Militare transformed into 'the navy’”.

Annamaria Testa, an advertising consultant and communications expert, told La Repubblica: “It seems a rather provincial approach. Why use the phrase “be cool”? There are plenty of equivalents in Italian.”

Employing an English slogan to drum up sailors for the Italian navy was “like putting ketchup on macaroni,” she said.

There were also critical comments on the Italian navy’s website, with one person wondering whether the adoption of English amounted to “war reparations” for Italian attacks on Royal Navy ships during the Second World War. “How can we be proud of our country if we don’t even use our own language?”

On the navy’s Facebook page, another indignant Italian wrote: “Are we now an American colony?”

But a spokesman for the navy said the campaign was intended to show the service as “modern, dynamic and international” and would appeal to an increasingly connected, internet-savvy younger generation.

Roberta Pinotti, the defence minister, said the campaign had succeeded in boosting applications to join the navy by 20 per cent since it was launched in January.

There was similar scorn this month when the city of Rome unveiled its new campaign to attract tourists.

Un essai de défense anti-missiles balistiques démontre la capacité de coordination multi plates-formes entre destroyers Aegis BMD

Un essai de défense anti-missiles balistiques démontre la capacité de coordination multi plates-formes entre destroyers Aegis BMD | Newsletter navale | Scoop.it

The US Missile Defense Agency (MDA) on 24 February demonstrated the ability of Aegis destroyers to co-ordinate and determine the best ship to engage multiple short-range ballistic missile targets launched near simultaneously.

The latest ballistic missile defence (BMD) test, which took place off the coast from Wallops Island, Virginia, demonstrated Lockheed Martin's Distributed Weighted Engagement Scheme (DWES).

The capability enables automatic engagement co-ordination between ships to help avoid having to launch multiple missiles to shoot down the targets, Paul Klammer, director of BMD programmes, integration, and strategy for Lockheed Martin, told reporters on 24 February.

"[We were] testing sophisticated algorithms that we put in place as [part of the] BMD 4 functionality to make sure these ships co-ordinated their engagements and to make sure that the ship that had the best shot at the target took it," he said.

"We reduced duplication of BMD engagements. It also saves on missile expenditures; from an inventory perspective it is important that that functionality works. It also gave us a great opportunity to test that the system works in a raid scenario where you have three very challenging short-range separating BMD targets."

For the test, USS Carney (DDG 64) and USS Gonzalez (DDG 66), both equipped with the Aegis Baseline 4 capability, acquired and tracked three short-range ballistic missile targets launched from NASA's Wallops Flight Facility, Klammer said.

"In this scenario one ship took two shots and one ship took one. The USS Gonzalez took two [shots] based on how DWES [determined] who had best shot. The system can be configured to automatically fire or have operator intervention," he said.

Both ships fired simulated Standard Missile-3s.

Lockheed Martin, the MDA and US Navy (USN) have a lot of data to go through from the event. Klammer noted the DWES algorithm that determines the preferred shooter performed as designed.

A third ship, USS Barry (DDG 52), equipped with Aegis baseline 9, also took part in the test, but it did not participate in the co-ordinated tracking and engagement of the three ballistic missile targets, he added.

"[ Barry was] tracking the three targets and doing simulated engagements similar to what the other ships were doing, except that [ Carney and Gonzalez ] were testing out DWES," Klammer said. " Barry gave us an opportunity to use the latest Baseline 9 build and make sure we could do simultaneous engagements in the same raid-type scenario."

The difference between Carney and Gonzalez equipped with Aegis Baseline 4 and Barry equipped with Baseline 9 is that the baseline 4 ships have a combination of the older UYK military-based and commercial off-the-shelf computers and rely on the ballistic signal processor functionality, Klammer noted.

Barry just received Baseline 9, which has the latest software configuration that brings an integrated air and missile defence capability to the ship. Baseline 9 also has the multi-mission signal processor, which is capable of conducting both air and BMD missions simultaneously.

Aegis Baseline 9 has DWES capability built in. Additionally two cruisers, USS Lake Erie (CG 70) and USS Shiloh (CG 67), have DWES functionality.

Les 24 patrouilleurs lance-missiles Ghannatha construits à Abu Dhabi par ADSB livrés aux Emirats

Les 24 patrouilleurs lance-missiles Ghannatha construits à Abu Dhabi par ADSB livrés aux Emirats | Newsletter navale | Scoop.it

Abu Dhabi Ship Building (ADSB) has announced the completion of the Ghannatha Phase II programme after delivery of all 24 vessels to the UAE Navy. Built to a design developed by partner Swede Ship Marine (Stand C-015), the Ghannatha-class boats are high-speed, aluminiumbuilt multi-role combat vessels. Powered by two MTU diesels driving twin Rolls-Royce FF 600 waterjets, the design is capable of speeds up to 45kts.

ADSB (Stand B-022) won the Ghannatha Phase II contract, valued at nearly AED1 billion, in 2009. Under the deal, the company has delivered 12 new 27m Ghannatha boats to the UAE Navy, and retrofitted modifications to 12 existing 25m craft.

Six of the original vessels have been modified as mortar boats,receiving the Patria Nemo 120mm smooth-bore mortar system, plus an OTO Melara Hitrole-G 12.7mm gun mounting. These vessels have also received a GEM surveillance radar and updated VHF/UHF communications.

The other six 25m Ghannatha boats have been modified to serve as fast gun boats, equipped with a Rheinmetall MLG 27 27mm gun and a Hitrole-G 12.7mm mounting. They also retain the capability to embark up to 40 troops.

Swede Ship Marine, as ADSB’s principal sub-contractor, took responsibility for the design modification package for the 12 ‘stretched’ new-build vessels, and built the first three in Sweden.

The nine follow-on craft have been built by ADSB at its shipyard in Abu Dhabi’s Mussafah industrial area. As well as being 2m longer than the original 25m Ghannatha design, these later ships have also received more powerful MTU 12V 2000 M93 engines.

All 12 of the later ships are configured as missile boats, being equipped with four box launchers for MBDA Marte Mk 2/N surface-to- surface guided missiles. The Marte Mk 2/N missile is able to strike targets at ranges in excess of 30km, flying a fire-and-forget sea-skimming profile using mid-course inertial guidance and active radar homing. The vessels are also fitted with a mini-combat system supplied by Selex ES and a GEM radar for surveillance and target indication.

Abu Dhabi Systems Integration (ADSI) has taken responsibility for combat system engineering and integration activities for the Ghannatha Phase II programme. ADSI, a joint venture between ADSB and Selex ES, has overseen combat system definition and design, production, support to installation, setting-to-work, integration, commissioning and acceptance.

Piriou va construire deux patrouilleurs de 32 mètres (CPV 105) à Concarneau sur fonds propres

Piriou va construire deux patrouilleurs de 32 mètres (CPV 105)  à Concarneau sur fonds propres | Newsletter navale | Scoop.it

Piriou va lancer la construction de ses deux premiers patrouilleurs côtiers. Il s’agit d’unités de 32.5 mètres de long et 6.4 mètres de large du type CPV 105, l’un des nouveaux designs dévoilés par le chantier breton fin 2014. La découpe de la première tôle de la tête de série interviendra à Concarneau vendredi, et sera symboliquement présidée par le ministre de la Défense, Jean-Yves Le Drian, à l’occasion de sa visite du site.

Ces deux patrouilleurs ne sont, pour autant, pas destinés à la France, pas plus, assure-t-on de source industrielle, qu'à l'Arabie Saoudite. Piriou, qui ne dispose pas encore de produit éprouvé à la mer pour ce type de bâtiment, a en fait décidé de les réaliser sur fonds propres afin de disposer d'une première référence. Il s’agit donc de bateaux réalisés sans contrat, la société comptant les vendre au cours de leur construction ou une fois testés, sachant qu’ils seront opérationnels début 2016.

L'US Navy a accompli avec succès le 155ème test du missile balistique stratégique Trident II D5 depuis un SNLE classe Ohio

L'US Navy a accompli avec succès le 155ème test du missile balistique stratégique Trident II D5 depuis un SNLE classe Ohio | Newsletter navale | Scoop.it
The US Navy has successfully conducted the 155th test flight of two unarmed Lockheed Martin-built Trident II D5 Fleet ballistic missiles, which were launched in the Pacific Ocean from a submerged Ohio-class submarine.

Lockheed Martin Space Systems Strategic and Missile Defense Systems deputy and Fleet Ballistic Missile programmes vice-president Mat Joyce said: "These latest test flights demonstrate the reliability of the D5 missile and the readiness of the entire Trident strategic weapon system, every minute of every day.

"The navy programme office, the submarine crews and the industry team never rest to ensure the safety, security and performance of this crucial deterrence system."

Prior to testing, the missiles were adapted to test configurations using kits comprising a range safety devices and flight telemetry instrumentation.

The US Navy performs a series of operational system evaluation tests for the Trident strategic weapon system under the testing guidelines of the Joint Chiefs of Staff.

Trident II D5 is a three-stage, solid-propellant, inertial-guided ballistic missile, capable of travelling a range of 4,000nm while carrying multiple, independently targeted re-entry vehicles.

It is currently aboard the US Navy Ohio-class and UK Royal Navy Vanguard-class submarines.

The missile's design was completed in 1989 and was first deployed in 1990.

Lockheed Martin Space Systems is the strategic missile prime contractor for the US Navy's strategic systems programmes.

Le Président turc relance le projet de canal maritime pour
désengorger le Bosphore

Le Président turc relance le projet de canal maritime pour <br/>désengorger le Bosphore | Newsletter navale | Scoop.it

Istanbul, 24 Fév. 2015 (MAP)- Le président turc Recep Tayyip Erdogan a relancé le projet gigantesque du Canal d’Istanbul pour le désengorgement du Bosphore, une voie d’eau de 43 km entre la mer Noire et la mer de Marmara, lors d’une réunion avec des ministres concernés, rapporte la presse turque.

Avec une largeur de 400m et une profondeur de 25 m, selon la nouvelle version du projet, le canal sera enjambé de six ponts et transformera la partie européenne d’Istanbul, seule ville au monde à cheval sur deux continents, en une île artificielle, indique, mardi, le +Daily Sabah+. Lancé une première fois avant la campagne des législatives 2011, ce projet grandiose ressurgit à nouveau avant le scrutin électoral législatif (7 juin). Il sera conçu pour assurer le passage quotidien de 160 navires de très gros tonnages dont les supertankers et sera parallèle au Bosphore à l’ouest d’Istanbul.

Pour les autorités, le canal doit alléger le trafic sur le Bosphore et faire diminuer le risque d’accident dans le détroit large, en certains points, de seulement 700 m. Deux collisions s’étaient produites en 1979 et 1994 faisant respectivement 41 et 29 morts. Ce projet, devant être réalisé dans le cadre du partenariats public-privé, serait rentable avec la construction d’une nouvelle ville de 500 mille habitants le long des deux rives du canal au lieu de 1,2 million dans le projet initial de 2011 mais également grâce aux droits de péage contrairement aux statuts Bosphore et des Dardanelles, datant des accords de Montreux en 1936, prévoyant, en temps de paix, la libre circulation et sans aucun frais.

En liaison avec ce canal, les plans pour l’édification du troisième aéroport de la mégalopole turque ont été modifiés puisqu’il était prévu qu’une partie des 152 millions m3 de terre extraits lors du percement pourrait être utilisée dans la construction de cet aéroport, sur une ancienne région minière, à proximité de l’embouchure du canal sur la Mer Noire.

Cet aéroport, dont le coût global est estimé à 7 milliards de dollars, ambitionne d'être le plus grand aéroport au monde avec à terme 150 millions de passagers par an.(MAP).

Patrick H. 's insight:

Les russes avaient, en 2013, exprimé leurs craintes de voir, avec ce projet, l'équilibre militaro-politique régional déplacé en faveur de la Turquie et de ses alliés, dans la mesure où le canal artificiel risque de ne pas être soumis aux conditions de la convention de Montreux. On pourra lire l'analyse russe de cette affaire ici :

Le chantier naval Zenit construit de nouveaux patrouilleurs pour les garde-côtes et la Marine du Kazakhstan

Le chantier naval Zenit construit de nouveaux patrouilleurs pour les garde-côtes et la Marine du Kazakhstan | Newsletter navale | Scoop.it

Key Points

  • Shipyard to launch fifth Project 0300 Bars-class patrol vessel for the coastguard in April 2016.
  • Build work to start on a new navy Project 250 missile patrol boat in 2015.

Kazakhstan's Zenit Uralsk Shipyard is planning to launch a fifth Project 0300 Bars-class patrol vessel for the Kazakh coastguard service in April 2016.

The yard also will start work on a fourth Project 250 Kazakhstan (or Bars-MO)-class missile patrol boat for the country's navy, following a recent order from the Kazakh Defence Ministry. The construction of this ship is expected to take two years.

News of these developments was revealed on 16 February on the website of national defence company Kazakhstan Engineering, with the website citing local media reports.

Based on the Russian Project 22180 fast supply vessel design, the Project 0300 ships in service with Kazakhstan's coastguard - known formally as the Maritime Border Guard Service of the National Security Committee of Kazakhstan - are 41.75 m long, 7.8 m in beam, and have a draft of 2.5 m. They displace around 218 tonnes. Two MTU 16V4000 M71 series engines driving through ZF 7550A gearboxes provide a top speed of around 30 kt. Range is 1,200 n miles and endurance is 10 days. The ships' complement is 23. Armament typically comprises a 2M-3M gun mount with twin 14.5 mm machine guns, as well as 12.7 mm heavy machine guns.

The Project 250 patrol vessel for the Kazakh Navy is a further evolution of the Project 300 design with broadly similar hull specifications, although the 230-tonne full-load ships are slightly longer at 42.2 m and heavily armed in comparison to the coastguard ships. They are likely to be fitted with a Ukrainian combat system comprising the Kaskad-250 command-and-control system; an AK-306 gun controlled by a Sens-2-250 electro-optic device; the Arbalet-K system with four SA-N-10 Igla anti-aircraft missiles; a Baryer-VK launcher with four RK-2V anti-tank missiles; a Delta-250 2-D I-band air-/surface-search radar; and a Furuno navigational radar.

Meanwhile, Zenit is executing a major refit and modernisation of a coastguard 14 m Project 100M Sunkar-class patrol craft that entered service 11 years ago. The patrol craft in question is understood to be pennant number 503.

Oto Melara dévoile son nouveau canon léger et compact de 40mm au salon IDEX 2015 d'Abu Dhabi

Oto Melara dévoile son nouveau canon léger et compact de 40mm au salon IDEX 2015 d'Abu Dhabi | Newsletter navale | Scoop.it

At IDEX 2015 exhibition in Abu Dhabi, Italian company Oto Melara unveiled a new 40mm naval gun system weighting just below two tons. Thanks to its extremely reduced mass, small dimension, easy installation (no deck penetration required), modern and completely digital technology, Oto Melara believes the Forty Light will play a leading role as a 40mm naval system.

The full integration between high rate of fire and modern programmable ammunition enables the system to engage efficiently and effectively a large number of targets. In particular, the high operative flexibility allows to cover the most differentiated roles, typical of modern naval scenarios: generic surface threats, fast crafts, antiships helicopters and fast attacking aircraft as well as various missile typologies.
The gun mount operates with a high fire rate 40mm cannon fed through a 72 ready-to-fire rounds magazine capable of managing a dual feeding ammunition system. The system can be set up according to three different configurations based on customer requirements.
In remote control mode the system is completely slaved to the shipboard Command Management System, and the short reaction time in conjunction with the high accuracy guarantee excellent performances. The last generation digital architecture satisfies all the requirements coming from modern transmission technologies (serial link/LAN).

a local emergency control is required, in addition to the remote control mode it is possible to adopt the coaxial configuration that foresees a high performance daylight camera installed on the gun mount. This camera allows the system control in an emergency autonomous mode if the CMS is not available.
If a completely autonomous mode is required, it is possible to adopt a Stand Alone with Micro Fire Control System (MFCS) configuration based on an independent line of aim Sensor Suite equipped with a daylight sensor, a cooled IR sensor and a LRF (Laser Range Finder). The system integrates a predictive ballistic calculation based on muzzle velocity radar installed on the gun mount. An auto tracking module, capable of identifying and aiming an acquired target, can be installed as optional. The fully CMS slaved mode is still available and selectable.

In conclusion, OTO Melara FORTY LIGHT system provides all the expected 40mm ammunition performance with the advantage of a compact, versatile and flexible structure typical of a smaller caliber system. Moreover, the modern design fulfils the increasing need of easy maintainability and management.

La flotte de sous-marins de la classe Victoria est maintenant opérationnelle, et trois des quatre sous‑marins sont disponibles pour des opérations, indique le plus récent état de la flotte de la Marine royale canadienne en date du 19 février.

Les NCSM Windsor, Victoria et Chicoutimi étaient tous en mer en décembre 2014 et ont passé un total cumulatif d’environ 260 jours en mer en 2014.

Le NCSM Corner Brook est actuellement à quai au chantier Victoria Shipyards afin de se soumettre à sa période en cale sèche prolongée dans le cadre du contrat de soutien en service de la classe Victoria conclu avec Babcock Canada Inc. Il devrait y rester jusqu’en 2017.

Les sous-marins canadiens œuvrent généralement en un cycle opérationnel dans le cadre duquel chaque bâtiment est disponible auprès de la flotte pendant six ans, ce qu’on appelle la « période opérationnelle », suivie de deux ans de grands travaux de maintenance durant une période en cale sèche prolongée, indique la marine royale canadienne dans son état de la flotte.

En raison de leur petite taille et de leur système de propulsion électrique extrêmement silencieux, les sous-marins diesel-électriques conventionnels comme ceux de la classe Victoria sont dotés de capacités furtives et d’une manœuvrabilité accrue comme on a pu le voir avec le sous-marin Victoria lors de l’exercice RIMPAC 2012.

Ils possèdent des avantages dans certaines conditions par rapport aux sous-marins nucléaires, spécialement sur les côtes et dans des points d’étranglement stratégiques, ce qui fait d’eux un atout précieux pour le Canada et nos partenaires internationaux durant les années à venir...

...Outre représenter un atout stratégique pour le Canada, les sous-marins peuvent aussi jouer toute une gamme de rôles navals en temps de paix: surveillance des pêches, surveillance des trois côtes canadiennes, appui aux organismes maritimes d’application de la loi et aux autres ministères, dissuasion des terroristes, contrebandiers et pollueurs potentiels, etc.
