KOCHI (India), September 25 (RIA Novosti)


A Russian-built aircraft carrier is to be handed over to the Indian Navy on November 15, and will reach India by February 2014, a senior official at the Russian arms exports monopoly said Wednesday.


The Vikramaditya carrier, which is already years past its original 2008 delivery date, was supposed to have been handed over to India in December 2012, but last year’s sea trials revealed that the vessel's boilers were not fully functional.


“We expect that Vikramaditya will dock at a Mumbai port by February,” Viktor Komardin, deputy head of the state-run arms exporter Rosoboronexport, said Wednesday at the NAMEXPO-2013 naval exhibition in India.


Komardin said that the carrier would dock at 14 ports on its way to the final destination.


The carrier, renamed the Vikramaditya for India, was originally built as the Soviet Project 1143.4 class aircraft carrier Admiral Gorshkov.

Aircraft Carrier Vikramaditya To Join Indian Navy In Nov

September 18, 2013 by Shiv Aroor - Livefist


With all trials successfully completed in the White Sea and Barents Sea, the Vikramaditya (formerly Admiral Gorshkov) aircraft carrier will be commissioned into Indian Navy service between November 15-20 at the Sevmash shipyard in Severodvinsk, Russia.


The $2.33-billion deal finally delivers nearly a decade after it was signed, and after years of financial and technical turmoil. All considered, the deal goes down as one of the most ill-planned, where virtually every aspect of work on the ship was astonishingly underestimated by both sides, compelling an embarrassing price revision years after contract signature.


Well, now she's Indian, and she'll be most welcome. Shano Varuna!

US Carrier Contract Award Delayed

A composite photo illustration representing the Ford-class aircraft carrier, USS John F. Kennedy (CVN 79). (Navy)


Sep. 13, 2013 - By CHRISTOPHER P. CAVAS – Defense News


WASHINGTON — Negotiations continue between the US Navy and shipbuilders Huntington Ingalls Industries (HII) over the primary construction contract for the next aircraft carrier, even as the goal of a September contract award will pass with no action.


Sources said neither side sees a serious impediment to eventual agreement, and each agreed a Navy decision to continue support for preparation work will give negotiators more time to reach an accord.


“This decision was not impacted or driven by sequestration,” said Cmdr. Thurraya Kent, a Navy spokeswoman at the Pentagon. The delay “is to avoid any production break, continue negotiations, and keep the ship’s delivery date unchanged.”


The ship is the future John F. Kennedy (CVN 79), second ship in the new Gerald R. Ford-class of carriers. Like all previous nuclear carriers, the ship will be built at HII’s Newport News Shipbuilding yard in Virginia. Kennedy is scheduled to be delivered in September 2022.


The Navy estimates the carrier will cost $11.3 billion to build.


While the detailed design and construction contract had been scheduled to be awarded this month, the shipbuilder has received at least a dozen significant contracts or contract modifications for the ship since January 2009. The most recent contract announcement was made on May 6, when the company received a $60.8 million modification to buy long-lead items and continue preparation work. That work is expected to be completed by October 2015.


Delays in awarding significant ship construction contracts are not unknown. The final contract award for the DDG 1001 destroyer, for example, was delayed in 2011 while the Navy and General Dynamics continued negotiations, but also worked together to ensure progress continued on the ship, being built at Bath Iron Works in Bath, Maine.


Several sources felt it would not be unusual for CVN 79 contract negotiations to continue into the spring.


The carrier program came under intense criticism this month from the Government Accountability Office (GAO), which issued a highly critical report on Sept. 5.


Ironically, the government rejected a GAO recommendation to delay award of the detail, design and construction contract.


“Remaining technical and design risks with the lead ship could interfere with the Navy’s ability to achieve its desired cost savings for CVN 79,” the GAO said in the report. “These uncertainties also affect the soundness of the Navy’s current CVN 79 cost estimate, which is optimistic. These factors, when coupled with the existing sole source environment for aircraft carrier construction, may compromise the government’s negotiating position for CVN 79.”


Michele Mackin, who led the GAO carrier study effort, noted the delay is “interesting for us because we just recommended that they delay the award and they disagreed. And now, two weeks later, they delay it.”


A delay in the contract, Mackin said, would help in the understanding of the impact of several key systems still under development.


“There are still pretty significant unknowns with the electromagnetic aircraft launch system and the advanced arresting gear and other developmental technologies,” she said. “We think the government would be in a better negotiating position, with better insight and more knowledge about the test results of the developmental systems.


“This is a sole-source contract, and the government is not necessarily in the best position,” she added, “so the more they know about the costs of the lead ship the more information they’ll have to negotiate the second ship.


“The current contract they have expires in October 2015, so there’s time.”


Here is the Navy’s full statement on the contract delay:


“The Navy continues to negotiate with Huntington Ingalls Industries - Newport News Shipbuilding (HII-NNS) for award of the Detail Design and Construction (DD&C) contract of JOHN F. KENNEDY CVN 79. Until these negotiations conclude, the Navy intends to extend the current Construction Preparation Contract to authorize planning, material procurement, and discrete work that are aligned with the ship’s optimal build plan. Extension of the Construction Preparation contract avoids a costly production break.


“Negotiations on the DD&C contract will allow HII and the Navy to account for construction process improvements and other cost reduction opportunities which were outlined in the Navy’s May 2013 Report to Congress on CVN 79. Extension of the Construction Preparation contract will not impact the ship’s funding profile, ship’s delivery date, or the cost cap. ENTERPRISE (CVN 80) [the third unit in the CVN 78 class] is not affected by this decision.


“JOHN F. KENNEDY began Advanced Construction in December 2010 and was named by [Navy] Secretary [Ray] Mabus in May 2011. The ship will be the second aircraft carrier of the GERALD R. FORD class and is scheduled to deliver in Fiscal Year 2022. CVN 79 is the numerical replacement for USS NIMITZ (CVN 68) in the Navy’s force structure.”


Huntington Ingalls issued this statement:


“This action demonstrates the importance of continuing early unit construction and procurement of material for CVN 79 to the current plan of record while we jointly work to get a Detailed Design and Construction (DD&C) contract in place.


“This extension will help ensure that the fragile supplier base and our shipbuilders remain working, minimizing delay to ship delivery and associated cost increases.


“This extension also provides time for the Navy and industry team to implement lessons learned from CVN 78 construction, implement further construction process improvements, identify any government requirement reductions, and increase the maturity of government technologies in order to stay within a challenging budget.”

Les deux porte-avions britanniques avec tremplins et F-35B - crédits Royal Navy

Les deux porte-avions britanniques avec tremplins et F-35B - crédits Royal Navy

09 Sep 2013 By Ben Farmer, Defence Correspondent - telegraph.co.uk


Britain must have two working aircraft carriers if it wants to be a global military player, a Foreign Office parliamentary aide has said.


A Government cost-cutting proposal to mothball or sell one of two carriers being built would be a poor use of public money, Tobias Ellwood MP said in a report for a military think tank.

Trying to rely on a single carrier would also undermine the UK’s ability to cope with international crises.

Mr Ellwood said: “The UK either needs a carrier capability or it does not.

“If it does, then a minimum of two are required in order to have one permanently available.”

Running both carriers would cement Britain’s position as “a global player with a military power of the first rank,” he said.

The Government has yet to decide the fate of the two 65,000 ton Queen Elizabeth class carriers currently being built, but the 2010 defence review proposed selling one or keeping it mothballed to save money.

Mr Ellwood, in a report for the Royal United Services Institute, said: “A £3-billion carrier waiting in ‘suspended animation’ in Portsmouth to be activated has political consequences, as does the selling of a ship at a loss.

“Neither option is a sensible use of taxpayers’ money. Indeed, the latter should be firmly disregarded.”

He said the lack of British carriers during the 2011 Libya campaign had meant that RAF Tornadoes and Typhoons had been forced to fly a 3,000 mile round trip from the UK to hit Col Gaddafi’s forces.

Even when a base became available in Italy, he said air raids were still four times more expensive than if they had been launched from a carrier in the Mediterranean.

Mr Ellwood, a former Army officer, said: “The carrier’s agility and independence means it is likely to be one of the first assets deployed to any hotspot around the globe.”

He said a single carrier would only be available around 200 days per year because of maintenance work.

Last week backbenchers on the Public Accounts Committee warned the aircraft carrier programme faced further spiralling costs.

The project remained a “high risk” because technical problems had not been resolved and there was potential for “uncontrolled growth” in the final bill.

The committee also said a decision to change the type of planes to fly from the carriers had wasted tens of millions of pounds.

The Ministry of Defence had originally opted for jump jet versions of the F-35 Joint Strike Fighter, then switched to the carrier variant, only to return to the jump jets again last year when costs soared.

Philip Hammond, Defence Secretary, said no decision would be made on what to do with the two carriers until the 2015 strategic defence and security review.

But money saved by reverting to the jump jet F-35s meant there was the possibility of having two operational carriers.

He said: “Of course there are operational cost implications of holding two carriers available rather than one, but we will weigh very carefully the benefits of that and the costs of that in the review.”

Ground-breaking Radar for Aircraft Carriers Begins Testing at Secret Facility on Isle of Wight

Sep 9, 2013 ASDNews Source : BAE Systems PLC


A new 3D radar capable of cutting through interference equal to 10,000 mobile phone signals, has successfully commenced integration trials at a secret electromagnetic radar testing facility on the Isle of Wight.


The testing of ARTISAN 3D radar is in advance of installation on the new Queen Elizabeth Class Aircraft Carriers (QEC) which are being assembled in Rosyth, Scotland.


The ARTISAN trials will test a series of integrated systems which include the provision of 3D air surveillance, target identification and air traffic management services for the ships,   The ARTISAN 3D Radar will provide extensive air traffic control and medium range tactical picture capability with ground breaking features such as tracking more than 900 targets at one time and has the ability to spot objects as small as a tennis ball travelling up to three times the speed of sound.


The BAE Systems radar testing facility on the island occupies the site of the old Somerton Aerodrome which began as an airfield in 1916. As well as being equipped for the manufacture and test of aircraft components, the aerodrome operated flights between London and the Isle of Wight in the 1930s. The site was taken over by the Decca gramophone company in 1959 which had contributed to the war effort resulting in a number of ventures into marine radar and navigation. This heritage continues today through BAE Systems’ expert radar testing at the site.


ARTISAN 3D is successfully providing 'real world' tracks and radar video to the QEC Combat Management System - which is also produced by BAE Systems - whilst receiving simulated 'own-ship' data in the QEC Mission System Test Facility.  ARTISAN 3D is being successfully controlled from CMS consoles to provide operators with both a medium range tactical picture and the essential air traffic control picture the ships will rely on.


In addition to the strong integration results, the system is operating successfully with the QEC Identification Friend or Foe (IFF) system, which can identify aircraft as friendly and track its range from a potential threat.


The aircraft carriers HMS Queen Elizabeth and HMS Prince of Wales are being delivered by the Aircraft Carrier Alliance, a unique partnering relationship between BAE Systems, Thales UK, Babcock and the UK Ministry of Defence. The first ship will begin sea trials in 2017.


Les Gregory, Product and Training services Director, BAE Systems said, "I am delighted that the ARTISAN 3D Radar is producing excellent results as predicted for the QEC, it is an exciting milestone not only in the development of BAE Systems radar programme but for the future of Royal Navy warships."


The medium-range radar system, which has a reach of up to 200km completed its factory testing in December 2012 and was installed at the Aircraft Carrier Alliance Electromagnetic Environment Assessment facility at BAE Systems, Cowes, earlier this year.

INS Vikrant built by Cochin Shipyard Limited

INS Vikrant built by Cochin Shipyard Limited

05 September 2013 Vivek Kapur – Pacific Sentinel


The first indigenously designed and built aircraft carrier, INS Vikrant, was launched on August 12, 2013. While still several years from being operational, the launch of the carrier, which has been designed to carry 36 fixed wing fighter aircrafts, comprising a mix of MiG-29K and the indigenous LCA (naval variants) in addition to Ka-31 AEW and ALH helicopters, will provide air cover to Indian Navy (IN) vessels. The launching of the hull of INS Vikrant with the power plant and generators integrated is the first step in the further development of the ship, particularly the weapon systems. This work is likely to consume the better part of two years before the ship can join the operational fleet. Only the UK, the US, France, and Russia have demonstrated the ability to design and build such ships. Reportedly, the second Indigenous Aircraft Carrier (IAC-2) is under design already.
One particular feature of the aircraft carrier is that it does not plan to utilise steam catapults, like the US super carriers, for the launch of the fixed wing aircraft. Instead, the bow of the ship sports a ski-jump configuration, in which the aircraft rolling down the very short available runway on take off is lofted into the air like a skier.1 This will impose limitations on the type of aircraft operable. The IAC-2 is likely to have catapults for aircraft launch.
The importance of air power at sea can not be overstated especially since the Battle of Coral Sea (May 4–8, 1942), in which two opposing fleets fought a major sea battle through the use of aircrafts launched from their carriers. Replacement of the battleship of yore with aircraft carriers, as the new capital ship, has been a strategic choice for the navies of the world since then.


INS Viraat, currently the sole Indian aircraft carrier, operates British-made Sea Harrier2 fighters in addition to helicopters of various types. INS Vikrant’s MiG-29K fighters are modern fourth generation fighters that will provide the IN with state-of-the-art air defence capability through the use of advanced Beyond Visual Range (BVR) as well as Within Visual Range (WVR) missiles backed by advanced airborne radar and Infra-red search and Track (IRST) systems and excellent agility. The MiG-29K also has an anti-ship and anti-land target strike capability, which would help in vastly increasing the reach, safety and lethality of the fleets at sea.

The IN has fielded an aircraft carrier since 1961.3 The original INS Vikrant served from 1961 to 1997.4 Aspiring to field at least two carrier battle groups (CBGs), one each for the western and eastern seaboards, the IN negotiated for induction of the erstwhile Soviet carrier, the deactivated Admiral Gorshkov, while also commencing to design an indigenous aircraft carrier. The contract for its transfer of Admiral Gorshkov involved extensive refurbishment by Russia. The refurbishment has faced extensive delays and cost escalations, though the vessel is reportedly now nearing readiness.
The progress in the development of INS Vikrant indicates that India’s shipbuilding capabilities are maturing towards self-reliance in design and development of high-end naval vessels. At the higher end of naval equipment, the aircraft carrier and nuclear powered submarine are complex. By 2020, INS Vikrant should be ready for operational deployment and could be reasonably be expected to be joined in a few years by its sister ships that may include further refinements over the original design. Both INS Vikramaditya and INS Vikrant are expected to carry MiG-29K fighters, sourced from Russia, to be joined later by Hindustan Aeronautics Limited’s (HAL’s) Tejas (naval variant).
By the 2030s, the IN should be able to field three CBGs giving it the capability to protect India’s interests at locations far removed from the coast. The increasingly “designed and made in India” nature of the IN’s fleets should provide strategic and tactical flexibility through total ownership of critical technologies and capabilities. Air power afloat as an integral part of the Indian naval fleets should provide these vessels assured air defence and fire power against surface targets at sea and on land.
The IN has long aspired for a true blue water capability and the aircraft carrier project is a critical part of it. The IN has been involved in the project from the design stage onwards at the Cochin shipyard thus giving it total ownership. Also, the time and cost overruns in the indigenous aircraft carrier project are relatively minor. The Admiral Gorshkov’s refurbishment by Russian shipyards, with several decades of experience, stands as a comparison.5 The INS Vikrant is the lead ship of its class and future vessels of the same type, if built, should benefit from the from the construction process.
India has major maritime interests. These arise from the fact that most of India’s foreign trade is carried by sea. India’s energy imports also come by sea. Therefore, it is important for the country to be able to provide security along these sea lanes of communication (SLsOC). Moreover, with an expanding economy, India requires to be able to access raw materials sourced from other countries along the Indian Ocean rim as well as further away. Thus India must be able to freely access the SLsOC to these regions. The Indian Ocean hosts some of the most important SLOCs including the Straits of Hormuz and the Straits of Malacca. In international waters it is critical to have capabilities to protect national assets, particularly the sea passage choke points.
Naval fleets have the ability to stay on station for long and carry considerable integral firepower. An aircraft carrier bolsters the potency of naval fleets by deploying fighter aircrafts that can apply long distance power from their carrier. Carriers can provide intelligence, reconnaissance and other essential support functions as well. A carrier battle group thus enhances the power projection capability of its fleet manifold.
The INS Vikrant signifies the coming of age of India’s ability to design and build major warships in the country and much to cheer for the indigenous defence industry. Moreover, it indicates that the IN is close to achieving capabilities to field forces at long distances in order to safeguard India’s maritime interests.
Views expressed are of the author and do not necessarily reflect the views of the IDSA or of the Government of India.
  1. The upwards momentum imparted to the aircraft as it leaves the deck is designed to compensate for the very short available runway and, therefore, sub-optimal achieved speed due to the short take off run. The short take off run would result in lower speed than required for take off. However, the ski jump lofts the aircraft upwards; the additional height so gained allows the aircraft to build up adequate speed for a safe climb out.
  2. The Sea Harrier is an excellent aircraft with vertical landing and take off capability. However, its unique design restricts its radius of action, especially in vertical take off mode. Moreover, it was designed in the late 1950s and 1960s. Hence, its design has imitations in performance compared with modern fighters of later design.
  3. India bought the under-construction HMS Herculese Majestic class aircraft carrier from UK in 1957. Upon its completion in 1961, it was commissioned into the IN as INS Vikrant.
  4. INS Vikrant, which had commenced being built in 1943 and was finally completed in 1961, came to be decommissioned in 1997. IN bought the ex-Royal Navy HMS Hermes and induced it as the INS Viraat to replace the first INS Vikrant. The Viraat also boasts a ski jump configuration and came equipped to operate the Sea Harrier fighters in addition to helicopters.
  5. Initially, the Admiral Gorshkov was to be given free to India with India paying $800 million for its refurbishment and another $1 billion for MiG-29 fighters and other equipment. The final cost is in the range of $2.33 billion. Initial entry into service date was to be October 2008 with delivery finally delayed to October 2013.

September 4, 2013 By  Zachary Keck - http://thediplomat.com


Russia’s only aircraft carrier will visit Tartus’s small naval base in Syria later this year, BBC Monitoring reported citing a newspaper published by the Russian government.


“At the end of the year, most likely in early December, the Project 11435 heavy aircraft-carrying cruiser the Admiral Kuznetsov will set off on a long-distance sea voyage during which it will call at the Russian Federation Navy's logistical support centre located in the Syrian city of Tartus,” Russia’s Defense Ministry said in a statement, BBC Monitoring reported on Saturday, citing a Russian-language report in Rossiyskaya Gazeta, a newspaper run by the Russian government.


The article goes on to quote a Defense Ministry staffer as saying that the route of the vessel’s “long-distance sea voyage” was already set and it was therefore unlikely to be affected by the civil war in Syria. The Admiral Kuznetsov’s stopover in Tartus is “in no way connected” to the Syrian civil war Rossiyskaya Gazeta paraphrased the staffer as saying, according to BBC Monitoring.


The Admiral Kuznetsov is Russia’s only operational aircraft carrier. The article clarifies that Russia refers to the ship as an aircraft-carrying cruiser because “under international treaties aircraft carriers are banned from passing through the Bosporus and Dardanelles…. But this ban does not extend to aircraft-carrying cruisers.”


According to the article, the carrier can hold 50 airplanes and helicopters and comes equipped with “Granit antiship missiles, Kortik and Klinok surface-to-air missiles, and Udav antisubmarine warfare systems.” The article also reports that the Admiral Kuznetsov is 14,000 square meters and carries a crew of nearly 2,200 people including flight and technical personnel.

China to Have More Aircraft Carriers: Ministry Spokesman

BEIJING --- The Liaoning is the Chinese military's first aircraft carrier, but there will surely be more in future, a Ministry of National Defence spokesman said on Thursday.

China will comprehensively consider the development of aircraft carriers in accordance with the needs of national defense and military building, spokesman Yang Yujun said.

Yang made the comment at a news briefing when asked to confirm media reports that China is producing its first domestically made aircraft carrier.

Currently, China operates one aircraft carrier, the Liaoning, which was refitted based on an unfinished Russian-made carrier and delivered to the Chinese Navy on Sept. 25, 2012.

The carrier's original design allows it to carry about 30 fixed-wing aircraft.

The Liaoning has conducted successful take-off and landing tests of its carrier-borne J-15 fighters, the main strike force of China's carrier group.

US Carrier Theodore Roosevelt Returns To Service

Aug. 29, 2013 - By CHRISTOPHER P. CAVAS  - Defense News


WASHINGTON — Four years to the day from when it was pushed across Hampton Roads, Va., to begin the biggest overhaul of its life, the aircraft carrier Theodore Roosevelt returned to Norfolk Naval Base — reconditioned, refueled and overall much spiffier than before.


The ship returned to base Thursday following four days of sea trials to validate the work and redelivery to the Navy.


The $2.622 billion refueling and complex overhaul (RCOH), carried out about midway through the ship’s planned 50-year active lifespan, is the most comprehensive shipyard period an aircraft carrier will undergo. All of the ship’s major systems are replaced, upgraded or renewed, and both nuclear reactors are refueled. The upgrades give the ships another 23 years or more of active service.


Roosevelt is the fourth carrier to undergo the full RCOH process, each at Newport News Shipbuilding in Newport News, Va. — where all today’s US aircraft carriers are built.


“The ship performed wonderfully. All the systems were operating well,” Chris Miner, the shipyard’s vice president of in-service aircraft carrier programs, said via satellite phone Thursday as Roosevelt headed back to Norfolk.


“The improved capabilities of the ship were shown to be operating properly,” he said. “At the end of the day, TR is [now] as capable as any carrier in the fleet.”


Unlike the previous three RCOHs, Roosevelt won’t be headed back to Newport News for another short shipyard period for work added on since the original work package was agreed to, or discovered during the overhaul.


“We moved a significant amount of work into the RCOH,” Miner explained, eliminating the need for a follow-on shipyard visit.


Completion of the RCOH was originally scheduled for February 2013, but was extended twice due to emergent work and additional modifications. The additional work, according to Naval Sea Systems Command, added about $153 million to the ship’s overall cost.


At peak, Newport News assigned about 4,000 employees to work on Roosevelt, Miner said. Those workers now have been transferred to other projects in the shipyard, including three other aircraft carriers:


■ The Abraham Lincoln arrived in late March to begin its RCOH, scheduled to be completed in late 2016.


■ The Gerald R. Ford, first of a new class of carriers, is under construction and scheduled to be launched this fall.


■ The Enterprise, the world’s first nuclear carrier, was towed to the shipyard in mid-June to undergo inactivation. When the work is complete, the ship will be towed around South America to Puget Sound Naval Shipyard in Bremerton, Wash., for final dismantling.


Three carriers already have completed the RCOH process: Nimitz in June 2001; Dwight D. Eisenhower in March 2005; and Carl Vinson in July 2009.

China to build more aircraft carriers

August 29, 2013, zeenews.india.com


Beijing: China on Thursday said it will build more aircraft carriers apart from the 'Liaoning' to boost its defence and military capabilities.


"There will surely be more addition to Chinese military's first aircraft carrier Liaoning, launched last year," said China's Defence Ministry spokesman Yang Yujun.


China will comprehensively consider the development of aircraft carriers in accordance with the needs of national defence and military building, he added.

The French Navy’s Fleet Support Service (SSF) signed off on the completion of the intermediate refit of nuclear-powered aircraft carrier Charles de Gaulle after six months’ work by DCNS. From hull to combat system, without forgetting compliance tests to the latest environmental standards, communications suite modernization or the refurbishment of the accommodation and recreation areas, the project involved some 950 people and 1 million person-hours’ work.


Maintenance and modernization


In addition to scheduled maintenance, the refit was used to undertake significant modernization. The work was performed in the Vauban drydock at the Toulon naval base. The ship was given a complete facelift that included the repainting of a total area of 26,000 square meters and the complete refurbishment of one of the main galleys. Other modernization work included the replacement of the stabilization computer.


The propulsion system and other shipboard systems and equipment were inspected, overhauled and tested to ensure optimal performance in operation. Some 35 kilometers of cabling was also installed with a view to the later installation of a state-of-the-art IP network.


CVN Charles de Gaulle underwent a thorough overhaul performed by teams assembled by DCNS and its partners, supported day-to-day by the ship’s crew.


Major contracting challenge, noteworthy team success


“Scheduled refits are essential to return a ship to ‘as new’ condition. This six-month period of intense contract maintenance and modernization is over. Other teams will now resume shore-based day-to-day monitoring of the ship’s systems and equipment,” said Franck Bouffety, the Group’s Charles de Gaulle program manager.


With over 1,000 tasks in progress each week, the Vauban drydock was very busy indeed. Despite the huge number of jobs to be performed, everything was completed on time. DCNS completed the 6,000 maintenance and modernisation ‘line tasks’ specified for this scheduled refit. In addition to the ship’s crew, all available staff based at the Toulon naval base were mobilized for the extended pit stop. Virtually every DCNS center contributed in one way or another. In all, the Group assigned almost 500 employees to the project.

Nouveau pacha pour le porte-avions (PA) Charles de Gaulle

 24/07/2013 Marine Nationale


Le vice amiral d’escadre Xavier Magne, commandant la Force d’action navale (ALFAN), a fait reconnaître le capitaine de vaisseau Pierre Vandier comme nouveau commandant du porte-avions (PA) Charles de Gaulle le mercredi 24 juillet.


Depuis le 12 juillet, dans le cadre de sa remontée en puissance, le PA Charles de Gaulle effectue son stage de mise en condition opérationnelle (MECO). Organisé dans le prolongement de sa période normale d’entretien et d’une importante relève de personnel, ce stage permet à l’équipage de s’entraîner afin de se réapproprier complètement le bâtiment et d’être prêt à participer si nécessaire à des missions opérationnelles.

Les avions du Groupe Aérien Embarqué (Gaé) ( Rafale, Super Étendard modernisé et avion de guet aérien Hawkeye) ont ainsi rejoint le porte-avions. Les pilotes s’entraînent de jour comme de nuit afin d’obtenir leurs qualifications opérationnelles.


Un nouveau pacha

En plein cœur de cette montée en puissance, le CV Pierre Vandier a succédé au CV Olivier Lebas. La carrière du commandant prenant est riche, elle peut s’axer sur 3 composantes principales:

- Une expertise aéronautique

Breveté pilote d’aviation embarquée en 1993, il acquiert ses qualifications opérationnelles sur Super Etendard Modernisé. Il prend par la suite le commandement de la Flottille 12F « Rafale » et mène pendant deux ans les expérimentations militaires du nouveau chasseur embarqué. En tant que pilote de chasse, il participe à toutes les opérations du GAé notamment en Ex-Yougoslavie, au Kosovo et en Afghanistan

- Une expertise maritime et «ressources humaines»

À sa sortie de l’ École navale en 1989, il rejoint l’aviso escorteur Commandant Bory en tant que chef de service, puis est affecté officier «conduite du navire» de la frégate de surveillance Prairial. Plus tard, il est chargé de la formation d’élèves-officiers sur le porte-hélicoptères Jeanne d’Arc. Il est affecté deux ans sur le porte-avions avant de prendre le commandement de la Frégate Légère Furtive Surcouf.

- Une expertise opérationnelle et interarmées.

Il participe à de nombreuses opérations : Guerre du Golfe, Ex-Yougoslavie, Kosovo et Afghanistan à plusieurs reprises. En 2008, il participe avec la FLF Surcouf à l’opération de libération des otages retenus par des pirates sur le voiler Le Ponant. En 2011, il assure, aux côtés d’un général français, la supervision des opérations aériennes de l’armée de l’Air et du Groupe Aéro Naval pour l’opération «Harmattan». De janvier à juin 2013, il dirige pendant six mois la cellule de crise Mali. À ce titre, il assure dès les premières heures de l’opération la conduite des opérations terrestres et aériennes et participe à la direction stratégique de la crise.

Trois questions au CV Pierre Vandier

·         Commandant, vous prenez le commandement du fleuron de la Marine nationale, quel effet cela fait-il ?

C'est une immense fierté que de se voir confier un bâtiment aussi prestigieux qui constitue le fer de lance de la Marine. Je suis très impressionné par l'engagement de l'équipage qui, a peine sorti d'une période d'entretien très intense, s'engage avec enthousiasme et professionnalisme dans la mise en condition opérationnelle du bâtiment et de son groupe aérien. Je ressens également une grande humilité face à cette responsabilité très importante qui demande un engagement total au service des armes de notre pays.

·         Le porte-avions sort d’une IEI, quel bilan tirez-vous de cette période d’indisponibilité ?

Cette période est un triple succès pour le porte-avions. Un succès du contenu de cet arrêt technique. Plus de 15 000 lignes de travaux et un million d'heures de travail ont été réalisés pendant cette période. Soit une densité quotidienne de travaux supérieure à celle de l'IPER de 2008, hors changement des cœurs.
C'est un succès sur les délais de cette IEI, puisque la date de fin de travaux a été respectée, ce qui est la preuve d'une excellente maitrise technique des industriels, des services de soutien et de l'équipage durant cette phase de travaux importante.
Enfin, un succès pour le savoir-faire de l'équipage puisqu'après 8 mois d'arrêt et seulement trois semaines après la reprise d'activité à la mer, nous sommes en train d'achever notre mise en condition opérationnelle par des entrainements de plus en plus proches des exigences des opérations réelles.

·         Enfin, quelles sont les perspectives du PA Charles de Gaulle à court terme ?

Le porte-avions devrait normalement recevoir dans quelques jours sa qualification opérationnelle. Cela veut dire qu'il sera apte à accomplir les missions que le chef des armées lui confiera. Pour l'équipage, après une année très dense et un début d'été sur les chapeaux de roues, c'est avant tout la perspective des permissions au mois d'aout qui permettront à nos marins de souffler et de profiter de l'été. Pendant toute cette période, une partie de l'équipage restera à bord pour assurer la sécurité du Charles de Gaulle à quai,  notamment de ses chaufferies nucléaires. Nous restons en permanence prêts à reprendre la mer si la situation l'exige.

DCNS termine les travaux d’entretien intermédiaire sur le porte-avions Charles de Gaulle

24/07/2013 DCNS


Le service de soutien de la flotte (SSF) a prononcé la fin de l’arrêt technique du porte-avions Charles de Gaulle au terme de 6 mois de travaux réalisés par DCNS. De la coque au système de combat, en passant par le passage aux normes environnementales, la modernisation du réseau de télécommunication ou encore la rénovation des locaux de vie, ce sont 950 personnes et 1 million d’heures de travail qui ont été nécessaires.


Entretien et modernisation du navire


DCNS - PACDGCet arrêt technique a été l’occasion d’entretenir le navire et de le moderniser. Le porte-avions Charles de Gaulle aura notamment profité d’un passage au bassin Vauban de la base navale de Toulon. Le bâtiment a profité d’un lifting complet avec plus 26 000 m² de surfaces repeintes et la remise à neuf d’une des cuisines. Un certain nombre de modernisations ont été réalisées parmi lesquelles figure le remplacement du calculateur de stabilisation du navire. Toutes les installations à bord et l’ensemble de l’appareil propulsif ont été contrôlés, révisés et testés pour assurer le fonctionnement optimal en opérations. Par ailleurs, dans la perspective de l’installation ultérieure d’un réseau IP (internet protocol) de dernière génération, 35 km de câbles ont été passés.


Le porte-avions Charles de Gaulle a ainsi bénéficié d’un entretien minutieux réalisé par les équipes DCNS et leurs partenaires avec l’appui quotidien de l’équipage.


Un défi industriel, une réussite collective


« Ces six mois de travaux ont été essentiels pour redonner toute sa jeunesse au porte-avions Charles de Gaulle. La période d’intense activité industrielle est désormais terminée. Elle laisse place au début du suivi quotidien du navire depuis la terre », souligne Franck Bouffety, directeur des programmes porte-avions Charles de Gaulle chez DCNS.


Avec plus de 1 000 travaux en cours en permanence toutes les semaines, l’activité de ce chantier a été très intense. Malgré la multiplicité des tâches à accomplir, les délais ont été respectés. DCNS a achevé les 6 000 lignes de travaux nécessaires pour moderniser et entretenir le porte-avions Charles de Gaulle durant cet arrêt technique programmé. Outre les membres de l’équipage, la totalité des unités de production du site de Toulon se sont mobilisées pour le succès de cet « arrêt au stand ».

India’s Muddled Carrier Plans

July 10, 2013 by Robert Farley - Flashpoints


At long last, the delivery of INS Vikramaditya, the former Russian Admiral Gorshkov finally appears imminent. Vikramaditya is currently undergoing sea trials with a mixed Russian-Indian crew, and a transfer to Indian service is scheduled for the autumn.  The delivery comes several years late, but still perhaps in time for the Indian Navy to use the carrier as a test-bed for INS Vikrant, its first indigenous carrier, scheduled for commissioning in 2018.

However, while the delayed delivery of Vikramaditya has surely proven problematic for the Indian Navy, the program has an altogether broader set of problems. Unlike the PLAN, the Indian Navy has a long history of carrier operations, running from the Majestic class INS Vikrant to the former Centaur class INS Viraat.

But India’s carrier heritage may be less of an asset than it seems.  India doesn’t appear interested in achieving greater efficiency in many areas— even in terms of common training and operational procedures— with this path of carrier fleet development. 

With the arrival of Vikramaditya, the Indian Navy will be flying new aircraft off of a new carrier of largely unfamiliar design. Although the Indian Navy has experience with both carriers and with Russian vessels, its previous carriers have been of British design, and it has never operated a ship this large. 

Furthermore, no Kiev class carrier has been put to sea in an operational sense since the early 1990s, and the modifications to Vikramaditya make her a virtually new vessel in any case.  Even after delivery, Vikramaditya will require considerable practice and time to become an effective, operational unit. The MiG-29K is also relatively new to carrier operations, with the first aircraft entering service in 2011. 

Operational tempo in Russian service has thus far been slow, meaning that many of the kinks with the carrier-based version of the veteran fighter will have to be worked out in Indian service.  If India follows through on plans to build INS Vishal as a CATOBAR carrier, the Navy will again have to learn an entirely new set of procedures, presumably with a new generation of aircraft, in the next decade.

The most interesting points to watch will be Indian collaboration with other carrier-operating navies.  The obvious candidate is Russia, but Russia owns only one carrier, which operates at a relatively low temp and may shortly re-enter a prolonged refurbishment period.  The only other navy to operate a similar carrier will, ironically, be the PLAN, which is unlikely to share many of its developing operational procedures with the Indian Navy. 

The risk of duplication of effort can surely be overstated; some of the tacit knowledge of naval aviation operations will carry over from the STOVL Viraat to the STOBAR Vikramaditya and Vikrant to the CATOBAR Vishal. However, “knowledge efficiency” and modularity do not appear to be strongly valued by the Indian Navy; beginning in 2018, it will operate three carriers of radically different age, design, and capability, and will likely maintain that state of affairs into the medium term (even after Vishal replaces Viraat).

INS Vikramditya, India's second aircraft carrier, out at sea again

July 03, 2013 by Sudhi Ranjan Sen - ndtv.com


New Delhi: The INS Vikramditya, India's second aircraft carrier, is out at sea again. By this time tomorrow, the 45,550-ton vessel built at the Sevmash shipyard in Severodvinsk, north Russia, will be sailing through the Barents Sea.


Over the next two months at least, the ship will be put through stringent testing in the Barents Sea and the White sea. "If all goes well, the Indian tri-colour will be flying atop the INS Vikramaditya this November, after which it will start its journey to India," a senior Navy officer told NDTV.


The INS Vikramditya, formerly known as Admiral Gorskhov, was to have joined the Indian Navy last year. However, the insulation tiles of its boilers cracked during full power trials, which entail pushing the ship to maximum speed at sea and then testing all systems for accuracy and endurance.


The fire-brick lining - made of special ceramic to help maintain optimum temperature in the boilers - on the inside of the insulation had come off. A senior official told NDTV that the entire insulation was ripped off and a new one has been installed.


A 500-member Indian Navy team, which was training on-board the Admiral Gorshkov then had spotted the problem with the warship's boilers, especially when the vessel hit top speed of about 30 knots (around 55 kmph).


The repairs delayed delivery of the ship by a year. "Tests carried out in the dry docks have also been successful," the official said.


India and Russia had signed a $2.3-billion (Rs. 14,000 crore approximately at present valuation) contract for refitting the aircraft carrier, which served in the erstwhile Soviet Navy. The first contract was signed in 2004, when no other country was ready to sell such technology to India.


During the sea trails now, all systems of the ship, including its sensor and weapon and propulsion system will be tested and full power trails will be conducted again. A contingent of Indian Navy officials are on board to oversee and inspect the trials.

Nimitz-class aircraft carriers USS John C. Stennis and USS Abraham Lincoln

Nimitz-class aircraft carriers USS John C. Stennis and USS Abraham Lincoln

Jun. 13, 2013 - By CHRISTOPHER P. CAVAS   - Defense News


WASHINGTON — An amendment to reduce the statutory requirement that the US Navy keep 11 aircraft carriers in service was defeated June 13, first by voice vote and then by a recorded vote of 318-106.


Offered by Rep. Earl Blumenauer, D-Oreg., and co-sponsored by Rep. Mick Mulvaney, R-S.C., the amendment would lower the requirement to ten aircraft carriers.


Blumenauer, during the floor debate, explained the amendment would not limit the Navy to 10 carriers, but would rather give the service the ability to decide how many flattops would be active, not Congress.


“The Navy is going to have 11 carriers when the one under construction goes into operation. Nothing in this amendment denies them that,” Blumenauer said, referring to the carrier Gerald R. Ford, expected to be delivered in 2016.

“The amendment says that subsequently, going out 20, 30 years, the decision about the minimum level will be left to the Navy, not the Congress,” Blumenauer added.


The requirement to meet a set level, Blumenauer, “is a symbol of Congress micromanaging, substituting their judgment for the command structure.


“It’s important for us to express our confidence in them,” Blumenauer concluded.


Mulvaney concurred. “All we’re doing is giving the Navy more control over how many carriers the Navy has,” he said. “The amendment has no impact on national defense.”


But opponents, including Reps. Joe Courtney, D-Conn., and Randy Forbes, R-Va., reacted as though the amendment would limit both the number of carriers in service and Congress’ ability to decide that number.


“One of the things that unites Democrats and Republicans is that the Constitution mandates Congress to build strong navies. It mandates us and we will not walk away from that mandate,” declared Forbes.


Forbes and Courtney noted that Congress and the Navy agree on an 11-ship carrier force.


“Every [Quadrennial Defense Review] since 2011 says we need 11 carriers,” said Forbes.


“Strategy should drive decisions in Congress,” said Courtney. “The Navy has spoken with a report which clearly articulated an 11-carrier force.”

1st Carrier Countermeasure Anti-Torpedo Launched

Jun 7, 2013 ASDNews Source : US Navy


USS George H. W. Bush (CVN 77) conducted the first aircraft carrier-borne end-to-end at-sea test of the Surface Ship Torpedo Defense (SSTD) System, the Navy announced, June 6.


The SSTD System combines the passive detection capability of the Torpedo Warning System that not only finds torpedoes, but also classifies and tracks them, with the hard-kill capability of the Countermeasure Anti-Torpedo, an encapsulated miniature torpedo. The at-sea tests were conducted May 15-19.


The Countermeasure Anti-Torpedo is being developed by the Pennsylvania State University Applied Research Laboratory (PSU-ARL). It is designed to locate, home in on and destroy hostile torpedoes. Over the four-day testing period, Bush engaged seven torpedo-like targets with seven Countermeasure Anti-Torpedoes. Designed to validate the end-to-end of the system, the testing proved successful.


"These tests are a culmination of a very focused effort by the Navy including the program office, Bush's crew, Norfolk Naval Shipyard and our academic and industrial partners. With all seven of our shots doing what they are designed and built to do, it validates our work and significantly enhances our current capabilities," said Capt. Moises DelToro, the Undersea Defensive Warfare Systems program manager.


This first end-to-end test of the SSTD System achieved several firsts: the first Torpedo Warning System detection of targets from a carrier, the first automatic detection and automatic targeting of an incoming torpedo target from a ship, the first launch of Countermeasure Anti-Torpedo from a carrier and the first end to end Torpedo Warning System and Countermeasure Anti-Torpedo system detection-to-engage at-sea test.


"It is gratifying to have these tests go so well," said Rear Adm. David Johnson, program executive officer, Submarines, whose portfolio includes the Undersea Defensive Warfare Systems Program Office. "The engineering involved to detect a hostile torpedo, process its direction, speed, depth, and then engage it with a carrier-launched Countermeasure Anti-Torpedo is impressive. I am confident that the fleet will be pleased with the results."


Given the complexity of the system, the program office is taking an incremental approach to the development and acquisition of the Surface Ship Torpedo Defense System.


"What is currently aboard Bush is an engineering development model, or EDM, that is a fully-functioning system, but not the final configuration or production model," DelToro said. "We're learning from the Bush to improve the system so we can provide the most robust and cost-effective hard-kill anti-torpedo capability possible."


The Navy currently plans to equip all aircraft carriers and other high-value units with the Surface Ship Torpedo Defense system by 2035.

Toulon : sortie de bassin du porte-avions Charles de Gaulle

07/06/2013 DCNS Goup


Le 3 juin 2013, dans la base navale de Toulon, le porte-avions Charles de Gaulle est sorti du grand bassin Vauban. Le navire était entré au bassin au mois de janvier dernier dans le cadre d’un arrêt technique intermédiaire mené par DCNS, maître d’œuvre des opérations.


Cette phase de modernisation programmée, appelée IEI (Indisponibilité pour Entretien Intermédiaire) a pour but la rénovation de certaines installations. Durant ce passage au bassin, DCNS a réalisé l’entretien de la carène du navire et modernisé de nombreuses installations du porte-avions : systèmes de navigation et de combat, stabilisation de la plateforme…


Les travaux se poursuivent désormais à quai après cette étape, comme en témoigne Franck Bouffety, directeur des programmes MCO porte-avions chez DCNS : « Cette date marque notamment la fin des travaux d’entretien sur la coque, partie immergée du navire. Après cette phase au bassin, DCNS poursuit les travaux à quai avant la phase d’essais à la mer et de remontée en puissance des installations. »


Le porte-avions reprendra la mer au début de l’été pour une série d’essais de bon fonctionnement des installations, suivis d’une période de mise en condition opérationnelle.

The Russian Navy only aircraft carrier Admiral Kuznetsov was scheduled to go on the dry dock at Severodvinsk to begin a four-year upgrade, but due to the hightened tension in Syria it is likely to continue service unchanged, joining the new Mediterranean Task Force the Russian Navy is deploying to the Mediterranean sea.

The Russian Navy only aircraft carrier Admiral Kuznetsov was scheduled to go on the dry dock at Severodvinsk to begin a four-year upgrade, but due to the hightened tension in Syria it is likely to continue service unchanged, joining the new Mediterranean Task Force the Russian Navy is deploying to the Mediterranean sea.

June 2, 2013 by Tamir Eshel - Defense-Update.


The Russian Navy plans to deploy its single aircraft carrier in support of its newly formed Mediterranean task force, Commander Admiral Viktor Chirkov said, a declaration that could further escalate rhetorics over the Syrian conflict. The carrier “Admiral Kuznetsov” will be ready to join the naval task force by the end of 2013. Defense-Update reports.

Last year the Russian carrier was deployed off the Syrian coast supporting a two-week naval mission in the Mediterranean. The carrier returned to its home base in Severomorsk on February 17 2012 and was scheduled to enter a four year mid-life upgrade by year’s end.

The Russian Navy sought to replace the P-700 Granite anti-ship missiles with catapults, more hangars and new air defense systems, enabling the carrier to operate with more aircraft (MiG-29K fighters would have replaced the current Su-33s.)

The Russian Navy sought to replace the P-700 Granite anti-ship missiles with catapults, more hangars and new air defense systems, enabling the carrier to operate with more aircraft (MiG-29K fighters would have replaced the current Su-33s.)

The overhaul to be carried out by the Severodvinsk Sevmash shipyard would include the removal of the P-700 Granit anti-ship missiles, installing of catapults to the angled deck, and upgrading of the vessel’s powerplants. The air wing currently operating Su-33 fighters would expand, and convert to modern MiG-29K jets. Upgrades to the ship’s electronics and sensor equipment were also planned, along with the installation of the new anti-aircraft system. Admiral Kuznetsov was scheduled for a relaunch in 2017. Pushing back the refit seems to be a blow to the Navy, as the ‘Kuznetzov’ is already considered a ‘goulag’ for seamen, due to appalling living conditions on board.

This ambitious refit is now cut short, enabling the vessel to redeploy, responding to  heightened tension in the Eastern Mediterranean. Russia’s only Mediterranean naval base is at the Syrian port of Tartus. Moscow has been reinforcing its Mediterranean presence as the conflict in Syria has worsened. In March, warships from Russia’s Pacific Fleet entered the Mediterranean for the first time in decades to become part of what Moscow says is a permanent task force. That task force also includes vessels from the Northern, Baltic, and Black Sea fleets.

30 May 2013 naval-technology.com


The Indian Navy is planning to equip its second domestically built Vikrant-class aircraft carrier, INS Vishal, with General Atomics' (GA) new-generation catapult, Electro-Magnetic Aircraft Launch System (EMALS).


Currently, the Indian Navy is evaluating the EMALS programme for its 65,000t INS Vishal, which is still only a concept, while General Atomics recently briefed on the EMALS to the navy admirals.


A senior Indian Naval planner was quoted by Business Standard as saying that the INS Vishal may also feature a catapult assisted takeoff but arrested recovery (CATOBAR) system to support larger and diverse aircraft launch and recover missions.


The first ship of the class, INS Vikrant, currently under construction, features a short takeoff but arrested recovery (STOBAR) system.


During the meeting, General Atomics stated that the EMALS ships can support launch operations even in still conditions, while STOBAR aircraft carriers should maintain a speed of 20k-30k to generate wind-over-deck to support the mission.


An admiral said that the CATOBAR offers more options such as supporting operations of heavier fighters, AEW aircraft and, crucially, unmanned combat air vehicles (UCAVs), when compared with STOBAR systems.

"We could greatly expand our mission envelope with UCAVs, using the pilotless aircraft for high-risk reconnaissance and suppression of enemy air defences."


A naval planner said: "We could greatly expand our mission envelope with UCAVs, using the pilotless aircraft for high-risk reconnaissance and SEAD (suppression of enemy air defences)."


Equipped with six major subsystems. including prime power interface, launch motor, power conversion electronics, launch control, energy storage and energy distribution system, EMALS is also a choice for the US Navy's new aircraft carrier, USS Gerald R Ford (CVN 78).


In addition, EMALS provides reduced manning workload, reduced thermal signature, increased launch availability, reduced topside weight, reduced installed volume and launch capability for unmanned aerial vehicles.


Armed with close-in weapon system and OTO Melera 76mm Super Rapid guns, INS Vikrant and INS Vishal are expected to be delivered to the navy by 2017 and early 2020s respectively.
