Certains médias indiens affirment que le premier des six sous-marins Scorpène construits en Inde, dans le cadre d’un transfert de technologie du groupe français DCNS, vient d’être mis à l'eau. Annonce qui s'appuie sur les déclarations d'une « source haut placée de la marine indienne » mais qui apparaît prématurée.
« Le sous-marin est toujours en cours de réalisation, indique une source française proche du dossier. La mise à l’eau n’a pas encore eu lieu. Celle-ci devrait intervenir dans quelques mois. » Pour le moment, le sous-marin Scorpène se trouve donc toujours en cale sèche au chantier Mazagon Dock Limited, à Bombay, maître d’œuvre du contrat.
Le programme P-75 a été lancé en octobre 2005 entre l’Inde et la France et prévoit la construction de six Scorpène par le chantier indien Mazagon Dock Limited. Le premier sous-marin devait, initialement, être livré à la marine indienne en décembre 2012 et le dernier en décembre 2017.
Depuis, le calendrier a été recalé. Désormais, la livraison du premier Scorpène n’est plus prévue avant septembre 2016. Selon la presse indienne, les cinq autres suivront à la cadence d’un tous les neuf mois. Ce qui repousse la livraison du sixième sous-marin à la mi-2020.
Le programme a donc tourné au casse-tête pour DCNS, soucieux à la fois de ne pas froisser son partenaire indien et de ne pas compromettre son image de fiabilité. L’important retard est attribué aux difficultés de remise à niveau du chantier indien et à sa forte propension à ne pas respecter les procédures du transfert de technologie.
On notera que Mazagon Dock Limited, qui est un chantier étatique, n’a pas été sélectionné par le gouvernement Modri pour la construction en Inde de six sous-marins à propulsion anaréobie dans le cadre du programme P75i. Seuls deux chantiers privés, Larsen & Toubro et Pipavav, se trouveraient encore en lice.
Ceux-ci feront nécessairement appel à des sociétés étrangères. Ce marché intéresse DCNS, qui a déjà conclu avec Pipavav un partenariat stratégique en vue de construire des navires militaires.
L'Inde a fait de la construction de sous-marins une priorité de défense. Aucun sous-marin conventionnel n'a été mis en service depuis quinze ans dans la marine indienne. Celle-ci ne dispose plus aujourd'hui que de 13 sous-marins opérationnels, neuf de type Kilo russe et quatre de type 209 allemand, après le retrait du service du INS Sindhurakshak, irréparable après avoir été victime d'une explosion au mois d'août 2013.

The Navy of Brazil and the Itaguaí Marine Construction (ICN) - a company formed by the Brazilian company Odebrecht Defense and the French shipyard DCNS - agreed a change in the construction schedule of the first Brazilian submarine Scorpene class (S-BR), the "Riachuelo" (S40).
According to this adjustment, the vessel shall open sea trials around the month of July 2017, which will delay its delivery to the Navy's operating sector for the second quarter 2018.
In the final half of 2009, the General Directorate of the forecast of the Navy Material (DGMM) was that the SBR-1 was ready in 2015 (see story "Schedule of supplies of submarines and EC725 helicopters" , published by the Naval Power in September 3, 2009). Later, the Submarine Development Program (PROSUB) Navy had its modified deployment. The new forecast, the "Riachuelo", first of the four conventional submarines to be built, would be ready in 2016 and, after completion of dock tests and sea, would be delivered to MB in mid 2017.
According to the Naval Power can determine at that time the ICN and the Navy examine the development of an amendment to the construction contract of the submarines that specify the new manufacturing schedule SBR-1, because it involves several changes in deadlines, both for technical targets to be achieved, as the result of financial disbursements.
The expectation on the operation of the ship is, however, a very positive level.
One of the points that draws the attention of Brazilian concerns remedies adopted by designers and French manufacturers, to ensure a standard of quiet operation of the ship.
It must be said that were found technical resources capable of reducing vibration and sound produced naturally by the submarine in its displacement. A set of devices that extends from the work of special shims of pipes attached to the inner walls of the boat, suitable to eject fatty flows.
Après la perte de 2 sous-marins en moins d’un an et un processus d’acquisition de nouveaux sous-marins au point mort, la marine indienne plaçait tous ses espoirs dans la construction de 6 sous-marins Scorpène, dans le cadre d’un transfert de technologies avec DCNS. Le projet est sur le point de connaître un nouveau revers conduisant à un 4è report consécutif de la livraison des sous-marins.
Le chantier naval indien Mazagon Dock Limited (MDL), qui construit les sous-marins avec l’assistance de DCNS, a déclaré que des éléments d’une importance critique devant être fournis par DCNS, n’ont pas été livrés alors que la date prévue est dépassée. Fait aggravant : les pièces attendues concernent toutes les sections du sous-marin, et leur absence devrait affecter l’avancement de la construction.
Le calendrier de livraison actuel a été fixé en novembre 2012 et les commandes de ces pièces ont été faites selon ce calendrier. Il prévoit que l’admission au service actif du 1er sous-marin doit avoir lieu en septembre 2016 et que les 5 autres doivent suivre avec un intervalle de 9 mois. C’est ce calendrier qui est maintenant remis en cause.
De son côté, MDL a terminé la construction des 6 coques et a fait des progrès dans l’équipement du 1er.
Le contre-amiral Rahul Shrawat, directeur de MDL a indiqué : « Au départ, ce projet a été retardé parce que des équipements devant être achetés par MDL ne l’avaient pas été à temps. A la suite d’une revue du projet, ce matériel a été acheté. Parmi ces équipements, certains sont arrivés, d’autres n’ont pas été livré alors que la date prévue est dépassée. Je suis forcé d’absorber les retards et, dans certains cas, je défais ce que j’ai fait parce que les pièces n’ont pas été livrées. » Il ajoute que le ministère de la défense a été informé de ce problème et DCNS a été pressée de livrer. « Si les livraisons de ces pièces interviennent aujourd’hui, je peux encore livrer le sous-marin à temps, » a-t-il expliqué. Interrogé sur l’éventualité d’une révision du calendrier de livraison, sa réponse a été : « je ne peux faire aucun commentaire tant que les pièces n’ont pas été livrées. »
Le premier des Scorpène serait prêt à être lancé en septembre 2015. Après un an d’essais, impliquant tous les systèmes dont des lancements d’armes, il devrait être prêt pour l’admission au service, soit en septembre 2016. « Les travaux se poursuivent 24 heures sur 24, 7 jours sur 7 sur le chantier, et nous sommes très motivés. Je croise les doigts, » a-t-il ajouté.
Cette semaine, le ministre indien de la défense Arun Jaitley a visité le chantier. Il n’a fait aucun commentaire sur la situation. Des sources haut placées ont confirmé qu’elles étaient informées sur le sujet et qu’elles agissaient.
India Today a contacté DCNS à Paris pour obtenir des explications sur ce retards. Ses emails sont restés sans réponse. Elle a été informée que les hauts responsables de DCNS étaient « en voyage ».
La construction des sous-marins n’est pas le seul problème
Alors que la construction des sous-marins est affectée par des retards, ce n’est pas le seul problème que rencontre le projet.
La marine indienne souhaite équiper ces sous-marins de la torpille Black Shark. Pourtant, aucun contrat n’a été conclu à ce jour. Ce blocage est la conséquence d’une escroquerie dans un autre contrat, pour la livraison d’hélicoptères. La torpille Black Shark est fabriquée par WASS, une filiale du groupe Finmeccanica, constructeur des hélicoptères en question. Ce n’est qu’au début de cette semaine que le ministère de la défense a finalement débloqué le contrat, mais il n’a pas encore été officiellement attribué.
La marine indienne souhaite aussi équiper les 5è et 6è Scorpène d’une propulsion anaérobie, qui permet au sous-marin de rester plus longtemps en plongée. C’est la Defence Research and Development Organisation (DRDO) qui a été chargée des recherches et de la fabrication, et la marine indienne reste dans l’incertitude. Des sources de la DRDO ont expliqué que « c’est un système de très haute technologie et un véritable défi. Nous y travaillons et nous espérons pouvoir respecter l’échéance fixée par la marine. »
Alongside a three-year delay in adding six new Scorpene submarines to its depleting ranks, the Indian Navy faces an even more disquieting prospect - the Scorpenes will start joining the fleet in 2016 without their main weapon, the heavyweight torpedo. Submarines carry two major weapons - missiles against ships and land targets, and torpedoes to sink enemy ships and submarines. Missiles can be intercepted by anti-missile systems; and they inflict less damage. Torpedoes are harder to intercept and they blast holes below the waterline that quickly flood their targets, sinking them. Inexplicably, the ministry of defence (MoD) has failed to buy torpedoes to arm the Scorpenes it contracted for in 2005. In 2008, after a global tender, Italian company WASS was selected to supply their Black Shark torpedoes that were specifically engineered for the Scorpene. In 2011, a price was finalised: about $300 million for 98 torpedoes. Yet, even today, the contract remains unsigned. Consequently, when the first Scorpene submarine is commissioned in 2016, it will be armed only with the Exocet anti-ship missile. Were it to be challenged by Pakistan's silent new Khalid-class submarines - the French Agosta-90B -the Scorpene will have empty torpedo tubes. Even if the new government signs the contract quickly, delivery would be unlikely before 2017. The MoD did not respond to Business Standard's emailed questions. A top-level navy planner laments the MoD's lack of accountability, contrasting it with how former navy chief, Admiral D K Joshi, took responsibility for warship accidents and resigned. Says the naval officer: "If a military person were responsible for commissioning a Rs 4,000 crore submarine without its primary armament, he would be charged with dereliction of duty." The delay in signing the torpedo contract followed accusations that WASS had won unfairly, a tactic commonly used by arms vendors who are confident the MoD will suspend the contract and order investigations. Eventually, Defence Minister A K Antony referred the matter to the Central Vigilance Commission, which found no indication of wrongdoing. Even so, the MoD continues to stonewall. The prospect of an unarmed Scorpene has sent alarm bells through a navy that is down to just 11 submarines, against a minimum of 18 that naval planners require for safeguarding India's maritime interests. Of 14 submarines in the fleet, three Russian Kilo-class vessels are unavailable: INS Sindhurakshak was destroyed in a cataclysmic explosion in Mumbai last August; INS Sindhuratna will take a year to repair after a fire in February. A third, INS Sindhukirti, was scuttled by Hindustan Shipyard Ltd, Visakhapatnam (HSL), which dismantled the submarine for refit in 2006 but cannot put it back together again. The navy is furious that a Rs 1,500 crore frontline submarine was lost because the MoD insisted on providing work to HSL, a public sector shipyard without expertise in submarine repair. Disregarding this experience, the MoD now insists that HSL builds one of the six new submarines being procured under the Rs 50,000 crore Project 75I. Cabinet sanction is being obtained for two to be built abroad and four in India - one in HSL and three in an unspecified shipyard, probably Mazagon Dock Ltd, Mumbai (MDL).
A senior admiral observes wryly, "INS Sindhukirti has already been destroyed by HSL. Now let us see whether it reduces Project 75I from six submarines to five." Building Project 75I in two Indian shipyards would also mean paying double for transfer of technology (ToT) -which includes supervisors, instructors, special tools, jigs, etc. In the Scorpene contract, MDL paid Rs 6000 crore for ToT. This would more than double if Project 75I is shared between two Indian shipyards. Even so, the die seems cast. Navy sources tell Business Standard that former secretary of defence production, R K Singh, who became home secretary and then joined the Bharatiya Janata Party, insisted on HSL's participation as a condition for Project 75I. The MoD took over HSL from the Ministry of Shipping in February 2010, a white elephant that the latter was glad to forego. The Rajya Sabha was informed on August 24, 2011 that HSL had accumulated losses of Rs 930 crore and a negative net worth of Rs 628 crore. The MoD is stonewalling another measure that the navy believes essential for overcoming the submarine shortage. With the Scorpene and Project 75I delayed, the navy has proposed extending the service life and providing a mid-life upgrade to the existing submarines, which have exceeded the dives and hours of service that manufacturers prescribe. That proposal has lain with the MoD for six months now, while the submarine fleet becoming increasingly more hazardous to operate.

Une traduction en français de cet article est proposée par Gilles Corlobe sur le Portail des sous-marins :
Project 75 is one of India's most closely guarded military projects, almost as inaccessible to outsiders as the nuclear ballistic missile submarine, INS Arihant, nearing completion in Visakhapatnam. In a giant shed in the East Yard of Mazagon Dock Ltd, Mumbai (MDL), a 200-feet-long, cigar-shaped, metal cylinder is the first of six conventionally powered Scorpene submarines that the Indian Navy contracted to build with Franco-Spanish company, Armaris (since taken over by French shipbuilding major, DCNS). The boat (as submariners call their vessels) is obviously close to completion - a small remaining gap at the rear will be filled by the section that holds the engine. Nearby, a second Scorpene is taking shape, metallic rings being welded together to form a hull. In the shed next door, a third vessel is racing towards completion. Hundreds of MDL workmen swarm over the scaffolding that encases the three submarines, overseen by 25-30 French experts from DCNS. They are fitting the wiring, piping and combat systems that must function silently and efficiently in the most taxing underwater conditions. Business Standard has repeatedly applied to visit this facility but has been turned down each time. The description above comes from a trusted source, with intimate access to the Scorpene project. The ministry of defence (MoD) discourages the media after years of negative publicity over a project running four years late. Yet, MDL's current chairman, Rear Admiral (Retired) Rahul Shrawat - who inherited the Scorpene delay when he assumed charge of MDL - is upbeat. He promises the first submarine by September 2016, and to deliver the next five Scorpenes at nine-month intervals rather than the one-year intervals contracted. Speaking to Business Standard, Shrawat promised: "We will launch the first Scorpene by September 2015 and deliver it to the navy within a year, i.e. by September 2016. The subsequent boats will be delivered at nine-month intervals, with the sixth and final vessel joining the fleet by June 2020. Shrawat admits this is an aggressive timeline without any buffers for unexpected delays. As Business Standard first reported (Scorpene tangled in govt web, December 19, 2009) Project 75 was delayed by a sloppy Rs 18,798 crore contract that made MDL responsible for buying Rs 2,700 crore worth of Scorpene internal equipment from DCNS. When MDL ordered, DCNS cited inflation to raise the price to Rs 4,700 crore. The ensuing negotiations, and the lengthy processes for fresh government sanctions for added costs, caused over two years of delay. "Many significant items are yet to be delivered to us, even for the first submarine. This is a big criticality but we will meet the challenge," says Shrawat confidently. The Scorpene delay is part of a critical shortfall of operational submarines with the navy. The fleet has just 10 Sindhughosh-class (Russian Kilo-class) submarines, and four Shishumar-class (German HDW) submarines, of which just 9-10 were operational at any time. The availability fell to 7-8 after two recent submarine accidents - the sinking of INS Sindhurakshak in Mumbai after a cataclysmic explosion on board that killed 18 crewmembers last August; and a fire on board INS Sindhuratna in February that killed two officers and led to the resignation of the navy chief. Even so, Project 75 has created confidence about MDL's new ability to build submarines. The shipyard is readying to build a second line of six submarines under the new Project 75I, worth an estimated Rs 50,000 crore ($8.25 billion). Government sanction is being processed for Project 75I. Rather than floating a global tender for Project 75I, Shrawat wants to take advantage of the experience and expertise gained during Project 75. Instead of having a fourth type of submarine in the navy's fleet (in addition to the Kilo-class; HDW and Scorpene), MDL sees the benefit in a more modern Scorpene with air independent propulsion (AIP) and land-attack missiles that the Project 75 vessels lack. Only the last two Project 75 vessels are slated to have AIP. "Most naval policymakers would not consider it prudent to have a fourth type of conventional submarine in the fleet. I'm sure the government will feel the same. So, why not build more Scorpenes; improved with AIP and land attack missiles," says Shrawat. The defence ministry, led by A K Antony for the last eight years, consistently shrank from such decisions in favour of a single vendor, preferring the path of open tendering even when it created operational drawbacks, like a multiplicity of platforms. The next government's orientation will be keenly watched. Another key factor in the Project 75I decision would be the willingness of foreign governments to supply submarines equipped with land attack missiles. The Missile Technology Control Regime (MACRO) proscribes the transfer of missiles with ranges of 300 km and more. Meanwhile, Indian defence shipyards are jostling fiercely for a share of Project 75I. The navy wants two submarines built abroad and inducted quickly into service, with the remaining four being built by MDL and the newly acquired defence shipyard, Hindustan Shipyard Ltd (HSL). But L&T cites its key role in building the nuclear submarine, INS Arihant, to argue that it should build at least one Project 75I submarine.
This is the first good news for India's fast depleting submarine fleet in a long time. The first of the six Scorpene attack submarines being built at Mumbai's Mazagon Docks Ltd (MDL), under transfer of technology from France's DCNS, is now floating in the water.
This is an indication that the delivery of the submarines, delayed by over four years, is finally on track. The revised deadline for the delivery of the first Scorpene to the Indian Navy is September 2016. Thereafter, the delivery of the subsequent five has been promised at the rate of one every nine months.
A submarine is assembled in dry dock. Floating it in water is an indication that it's in an advanced stage of completion. In technical terminology, this marks the "launch" of the submarine.
"Both the pressure and the outer hull of the first Scorpene are in place. Much of the internal fit is also progressing well. The submarine will now be placed on a pontoon, and tugged out of MDL docks to the nearby Indian Navy Dock. This will free one precious submarine-building dock at MDL, and thus help in meeting deadlines for subsequent Scorpenes. The remaining work on the first submarine, in particular the fitment of batteries, will be done in the Naval Dock," a highly-placed source in the Indian Navy disclosed to The Sunday Guardian.
After the fitment is complete in the Naval Dock, the first Scorpene will be put through harbour trials. Once it clears the harbour trials, the boat will head for sea trials, during which its weapons firing capability will also be validated, before finally being inducted as a warship.
The Scorpene is one of the world's most advanced and stealthy diesel-electrical submarines. It will be armed with Exocet missiles and Black Shark torpedoes.
This marks a desperately-needed relief for the Indian Navy, which has lost five submarines in the last 15 years due to decommissioning or phase-out and accident, but not added a single new conventional submarine.
The Sunday Guardian had reported last week the retirement of INS Sindhurakshak, a Kilo class submarine, which suffered a catastrophic on-board explosion, rendering another blow to India's underwater strength. The number of conventional submarines is down to 13, of which three are in life extension refit. Another six are due for similar life extensions. Due to the critically-low force levels, these will be spared only after the Scorpenes start coming in.
A recent CAG performance audit has brought out the desperation. It disclosed that the operational availability of submarines is as low as 50% of those not in elaborate repair or refit.
The only addition to India's underwater fleet in nearly 15 years was a nuclear-powered Akula class attack submarine, codenamed INS Chakra, in 2012. This has been taken on a 10-year lease from Russia.
To maintain minimum numbers of conventional submarines, India embarked on a 30-year programme in 1999 to build 24 submarines. The programme is alarmingly behind schedule. The contract for the Scorpenes, which were to be the first element, was signed in 2005. The first submarine was scheduled to be delivered in 2012, but is now over four years behind schedule. Timeline slippages also led to heavy cost escalation from the initially contracted Rs 18,798 crore to Rs 23,562 crore.
Because of the huge delay in the Scorpenes and then in deciding on a second line of submarines, the Indian Navy has already obtained government approval for converting the requirement for six of the 24 conventional submarines into nuclear-powered ones (SSNs) akin to the leased INS Chakra. This is also significant from the point of view of increasing forays by Chinese nuclear submarines in waters close to India.

L'information publiée hier était inexacte ; j'ai donc corrigé le titre pour qu'il reflète la teneur exacte de l'évènement ! merci à ceux qui me l'ont signalé.
A Royal Malaysian Navy (RMN) Scorpène-class submarine carried out the service's first successful firing of a Whitehead Alenia Sistemi Subacquei (WASS) Black Shark torpedo on 31 October.
KD Tun Abdul Razak fired the torpedo against a 55 m passenger ferry that had been converted into a target. It subsequently sank.
The firing exercise, called Operation 'Barracuda 1/2014', was carried out at an disclosed location of the east Malaysian portion of the South China Sea. The exercise also involved frigate KD Jebat , patrol vessel KD Terengganu , corvettes KD Kasturi , KD Laksamana Tan Pusmah , submarine rescue vessel Mega Bakti , and a CB90 combat boat, while aerial assets involved were a RMN Eurocopter AS550 Fennec helicopter, a Royal Malaysian Air Force Beechcraft B200T Super King Air, and a EC725 helicopter.
The specific conditions of the Baltic Sea are favourable for the use of submarines and make them very difficult to detect, unlike land and air platforms for launching deterrent weapons. The ability to operate underwater for several weeks, provided by air-independent propulsion systems, in particular, makes undetectable and omnipresent modern submarines the most effective carriers of cruise missiles. The Scorpène has been designed to carry the MdCN naval cruise missile. Deterrence is the capability of a State to inflict sufficiently heavy losses on a potential adversary to deter it from attempting an attack. It is a key element of national defence for guaranteeing the protection of one territory. What differentiates cruise missiles from other weapons is their range, enabling them to reach targets deep in the territory of the adversary.
Cruise missile submarines, such as the Scorpène built by DCNS, have an effective offensive weapon system able to provide the deterrent capability wanted by Poland. This deterrence does not require a large number of missiles. The important factor is the ability to strike critical targets, with a high probability of success, within a radius of several hundred kilometres around the waters in which submarines can hide. No other weapon system can provide this capability. Cruise missile operation capability must be integrated into submarines at the design stage, and this is the case for the Scorpène configuration proposed to the Polish Navy by DCNS. The missiles have been developed by defence group MBDA for the French armed forces. The missiles are scheduled to enter service in 2015. The MdCN cruise missile can strike distant land targets with very high precision, thanks to its guidance system, reducing the risk of collateral damage. The cruise missile submarines will provide a guarantee of national protection. Furthermore, they will reinforce the diplomatic weight of Poland on the international stage. The fact that the Polish armed forces have the capability to launch cruise missiles from submarines will have a significant influence for Poland within NATO and the European Union, where only a few countries possess this capability. Poland will thus be able to join a very select club of countries with influence on the international stage.

Rappelons que 8 industriels de différentes nations seraient en compétition dans l'appel d'offres polonais :
The navy appears to be focusing on efforts to strengthen its undersea warfare capabilities to counter the rapid expansion of China’s submarine fleet. The main thrust of Admiral Robin Dhowan’s maiden visit to Vizag as navy chief is expected to be the refit of an attack submarine leased from Russia and deterrent patrols to be launched by India’s first nuclear-powered ballistic missile submarine. Dhowan’s two-day visit to the Vizag-based Eastern Naval Command (ENC) is seen as significant as the nuclear-powered submarine, INS Chakra, is set for a three-month refit, two years after the navy inducted the Akula-II class attack vessel. It is on a 10-year lease from Russia for almost Rs. 6,000 crore.
India, however, will complete its nuclear triad (ability to launch strategic weapons from land, air and sea) only when it inducts the indigenous ballistic missile submarine, INS Arihant. INS Chakra cannot deliver nuclear warheads in its current configuration.
The navy currently operates 13 submarines, compared to the 50-plus boats in the Chinese fleet. While Chinese submarines are growing in numbers and sophistication, India is grappling with an ageing fleet that has been involved in a number of mishaps.
A source said that Dhowan asked naval dockyards to take pride in maintaining older platforms to meet demanding resource challenges. He warned officers against mediocrity and asked them to take every incident seriously.
Dhowan is expected to take stock of the Scorpene project during an upcoming visit to the Mumbai-based Western Naval Command. Six Scorpene submarines are being built at the Mazagon Dock Ltd with technology from French firm DCNS under a Rs. 23,562-crore project codenamed P-75. But the first of these boats will be ready only by 2016-17, almost five years behind schedule.
Another priority for Dhowan would be to push the new government to speed up the acquisition of six new submarines under a Rs. 55,000-crore project codenamed P-75I.
DCNS vient d’inaugurer la plateforme d’intégration des systèmes de combat qui équiperont les futurs sous-marins brésiliens du type Scorpène. Cet outil dédié, installé sur un site de la Direction générale de l’armement (DGA) à Saint-Mandrier, permet de tester et d’éprouver à terre ces systèmes de traitement d’information très performants, qui permettent à l’équipage d’analyser l’environnement du sous-marin grâce à la compilation des informations perçues par les senseurs et de mettre en œuvre ses armes. « L’installation de cette solution innovante illustre la bonne avancée de la coopération liant DCNS et la Marine brésilienne autour de la conception et la réalisation de sous-marins dans le cadre d’un transfert de technologie. Les différents équipements constitutifs du système de combat des premiers sous-marins conventionnels de type Scorpène sont désormais assemblés sur cette plateforme à terre dans une configuration technique similaire à celle rencontrée à bord des sous-marins », explique DCNS.
