As part of Britain’s fiscal rebalancing, The Royal Navy is set to inherent the RAF’s Merlin HC3/3A medium-heavy battlefield helicopter fleet, while simultaneously upgrading its existing set of Merlin HM Mk1s. The entire effort approaches $3 billion for a final total of 55 refurbished helicopters, and these refurbishments will be carried out as part of the AW101 fleet’s long-term maintenance plan.
The navy’s existing fleet is being progressively upgraded and returned to service, adding a range of technological improvements to the helicopter’s avionics, control systems, sensors, and radar. The Royal Navy received 44 EH101 Merlin HM1s between 1998-2002 for training, surface attack and anti-submarine warfare duties, and has since lost 2 in accidents. The remaining 42 helicopters are now expected to remain in service until 2029, though only 30-38 will be upgraded. Another 28 EH101 Merlin HC3/ HC3A medium support helicopters currently serve with the UK Royal Air Force, and they will join the Navy to succeed the Sea King Mk.4 Commandos as the Royal Marines’ battlefield helicopters.
EH101 Merlin HM Mk1 helicopters will undergo GBP 1.15 billion ($2.04 billion at milestone conversion) in upgrades from original manufacturer AgustaWestland and Lockheed Martin UK. Originally built in the 1990s as an anti-submarine and search-and-rescue aircraft, the Merlin has taken on an increasingly wide range of roles. This extensive upgrade program is designed to give the Royal Navy upgrades in current capabilities, far greater operational flexibility, and reduced lifetime maintenance costs.
The Merlin Capability Sustainment Plus (MCSP) program will target 30 helicopters, with an option for a further 8. They will be progressively upgraded to Mk.2 status from 2010 at AgustaWestland’s Yeovil, UK facility, with Full Rate Production slated to begin in 2012. The new AW101 Merlin Mk2 helicopters began delivery in July 2013, with Full Operational Capability scheduled for 2014.
Merlin Mk.2sLockheed Martin UK is the lead integrator for MSCP, and it received a GBP 750 million contract to help implement an open systems electronics architecture in the helicopters; improve the mission systems processing capabilities; add new capabilities for the Merlin’s Blue Kestrel Radar and Sonar system; broaden datalinks; and upgrade the aircrew console and avionics, including large flat panel touch screens. On a tactical level, these improvements will enable 40 times the number of targets to be tracked compared to the Merlin Mk.1, improve submarine detection in shallow water, and enhance night operations.
While improved capabilities will flow from these upgrades, the primary goal is to resolve electronics obsolescence issues in the current Mk1 variant, and reduce through life support and operating costs. The UK already has an IMOS through-life support contract with AgustaWestland, but a different structure for the support contract will not, by itself, solve problems with the underlying technology.
Overall, this Mk.2 Merlin technology upgrade is expected to reduce pilot workload, cost of ownership, maintenance and weight while giving improved survivability, safety, aircraft handling and agility.
Lockheed’s team includes AEI, BAE, CAE, Selex, Smiths, Thales, and QinetiQ. The firm estimates that this order creates or secures around 1,400 jobs across the UK’s defense industry.
AgustaWestland: The Merlin Mk.4 Commando Sea King Mk.4The RAFs 28 Merlin HC3 battlefield helicopters are also due for conversion, in order to replace existing Sea King Commando Mk.4 helicopters used by the Royal Marines. Around 25 AW101s are likely to be updated to the Merlin Mk.4 configuration, which will include the same cockpit modernizations and obsolescence/ minor redesigns for the Mk.2, plus standard naval changes like a folding rotor head, strengthened landing gear, deck lashing points, and a fast roping point for the Royal Marines.
The contract wasn’t issued until early 2014, and the Sea Kings are all expected to retire in 2016. The 1st fully-converted Mk.4s won’t even be available for trials until Sept 2017, and IOC won’t take place until 2018.
To bridge that gap, an initial 7 Army Merlins will receive only the folding rotor head that’s required for shipboard use. These Merlin Mk.3i will serve as an interim bridge before the arrival of the full Mk.4 conversions.
AgustaWestland: The HEAT Is On AgustaWestland EH101An independent but closely related GBP 400 million contract was issued to AgustaWestland, who will design, produce and integrate the new avionics suite. The most visible feature will be the new cockpit primary flight displays, incorporating touch screen technology to deliver increased crew efficiency. An updated communication and navigation system will be a less visible but equally important set of changes.
The changes are an opportunity to incorporate more of an Open Systems Architecture (OSA) into the helicopter, using standard electronics components to make adaption faster and easier, instead of requiring expensive and time-consuming efforts to design proprietary circuits.
Mechanically, the MCSP program will also see AgustaWestland introduce its Helicopter Electro Actuation Technology (HEAT) onto the EH101 Merlin HM Mk1. HEAT introduces a cutting edge 3rd generation fly by wire system that uses electrical actuators to provide the control inputs to the helicopter’s rotor systems, instead of using hydraulic units. Unlike other fly-by-wire systems developed for helicopters, the AgustaWestland HEAT system uses electro-actuation for both the main and tail rotors. The brushless electric motor actuators incorporate quadruplex 4-lane architecture with fail technology, allowing the system to function safely even after failure of 2 of the systems. The electrical actuators are maintenance-free and, unlike mechanical systems, do not require the same rigging checks to be made post maintenance.
In naval operations, these systems will allow flights in poorer weather than was previously possible, while the improved handling gives the helicopter more agility and better handling in nap-of-the-earth flights.
The HEAT system’s components underwent extensive testing in 2005 that covered system performance, durability, vibration, environmental, high-intensity radiated fields and lightning strike protection. Results were positive.
Britain’s Bottom Line(s)Britain’s government actually has 2 bottom lines here. One is cost. Another is industrial.
The UK MoD expects AgustaWestland and Lockheed Martin’s upgrades to deliver cost reductions of around GBP 575 million by removing obsolete, hard to buy parts, and lower support costs. The project will “enable the cost-effective management of obsolescence on an aircraft which has components and design features that are becoming difficult to support…”
These deals also reflect the objectives of the UK’s Defence Industrial Strategy white paper, which seeks to safeguard national capabilities across strategically important industry sectors – including rotorcraft manufacturing and support.
Merlin IOS and associated programs are part of that drive. AgustaWestland’s managing director of military programmes, Alan Johnston, has noted that:
“The EH101 is the first helicopter in the world to utilise this advanced technology [HEAT] which will bring significant operational and cost benefits to customers. We are pleased that, by adopting the partnering principles being developed between AgustaWestland and the UK MoD, we will be able to introduce this important technology into the EH101 Merlin HM Mk1 fleet”
As Mr. Johnson alluded, The HEAT programme is being funded through an innovative contracting strategy which builds on the partnered principles outlined in the UK’s recent Defence Industrial Strategy (DIS) Draft. AgustaWestland will offset the HEAT system production costs against future cost of ownership savings that in future Merlin support contracts.
EH101 CockpitJust as politics has 2 bottom lines, so does the military. The difference is that instead of overall costs and industrial considerations, the military confronts the twin lines of overall costs and available capability.
Unfortunately, the Merlin has been problematic for the military’s 2nd bottom line. British Merlins have displayed low readiness rates, and this has been consistent over a number of years.
New technologies may help there. On the other hand, the 2006 announcements offered no indication of whether the planned modifications would address the structural issues that have already led to the loss of one British Merlin, or the issues that led Canada to ground its CH-149 Cormorant search and rescue fleet for several months. As DID’s coverage of the USA’s CSAR-X competition noted:
“Canada has grounded its EH101/CH-149 Cormorant search-and-rescue fleet due to persistent cracks in the tail rotor hub (cracks believed to have caused the crash of a British EH101 Merlin as well), and reassigned smaller “twin Huey” Bell 412/ CH-146 Griffon helicopters to that role. The Canadians are also experiencing EH101 maintenance requirements and costs about 200% higher than originally forecast.”
Contracts & Key Events 1st deliveriesAlthough the AW101 is an AgustaWestland product, Lockheed Martin UK was awarded the original Merlin Mk1 contract for the 44 Navy ASW/ASuW helicopters in 1991, with AgustaWestland acting as sub-prime. That structure has remained consistent for the Merlins, and Lockheed Martin UK is also one of AgustaWestland’s strategic partners providing support and training services under the IMOS through-life maintenance program. In practice, MCSP and IMOS are linked, because through-life maintenance milestones are the Navy’s preferred time to install capability upgrades.
May 28/18: Royal Navy receives HC4 The UK has taken delivery of the first of an eventual 25 AW101 Merlin HC4 helicopters. The delivery is part of the Royal Navy’s effort to modernize its fleet of transport helicopters. The entire effort approaches $3 billion for a final total of 55 refurbished helicopters, and these refurbishments will be carried out as part of the AW101 fleet’s long-term maintenance plan. After being upgraded and marinized under a $517 million contract, the Merlin HC4 heavy-lift transport helicopter will be operated by the RN’s Commando Helicopter Force. The Merlin HC4s replace the fleet of existing Sea King Commando Mk.4 helicopters, their updated configuration includes the same cockpit modernizations and redesigns as for the Mk.2, plus standard naval changes like a folding rotor head, strengthened landing gear, deck lashing points, and a fast roping point for the Royal Marines. The next milestone for the Merlin HC4 will be embarkation aboard the RN’s new aircraft carrier, HMS Queen Elizabeth.
October 20/15: The Royal Navy has received the first of seven AgustaWestland HC3 Merlin helicopters, forming the first tranche of 25 helicopters as part of the Merlin Capability Sustainment Program. With the seven helicopters expected to reach initial operating capability next spring, they will replace Sea King HC4s from March.
September 16/15: The Royal Navy’s fleet of Mk2 Merlin anti-submarine helicopters has achieved Full Operating Capability (FOC), with 24 of 30 helicopters now delivered. A part of the $1.2 billion Merlin Capability Sustainment Programme, the upgrading of the 30 helicopters follows a GBP750 million contract with prime contractor Lockheed Martin, with the first five helicopters delivered back in July 2013 after work began in 2010.
Merlin HC3Oct 1/14: All Navy. RAF Benson in Oxfordshire hosts the official ceremony that transfers the British Army’s 2 Support Helicopter Force squadrons to the Naval Commando Helicopter Force.
RAF 78 Squadron is disbanded at the ceremony, and 846 Naval Air Squadron stands up. It will remain at RAF Benson until Spring 2015, when the helicopters will finish their transfer to Royal Naval Air Station Yeovilton in Somerset. RAF 28 (Army Cooperation) Squadron will remain in its current role for a little while, in order to ensure that enough helicopters are in place while the Army’s CH-47 Chinooks and AS332 Pumas are upgraded, RAF 28 squadron will formally disband later in 2015, and stand up as 845 Naval Air Squadron before it also moves to Yeovilton. Sources: RAF, “Royal Air Force Hand Over Merlin To Royal Navy”.
Full handover to Navy
July 14/14: Mk2. UK Minister for Defence Equipment, Support and Technology Philip Dunne announces that the Merlin Mk.2 has already entered service with the Royal Navy, 4 months ahead of the original schedule. Sources: UK MoD, “Navy’s sub-hunting helicopters enter service early”.
Jan 28/14: Mk4/4i. The Navy’s long-expected “Mk.4” upgrade (q.v. Jan 18/11) to the Army’s transferred Merlin HC3 helicopters is signed as the GBP 330 million (about $545 million) Merlin Life Sustainment Programme, which is a lot less expensive that the GBP 454 million originally reported by Aviation Week. MLSP will modify the helicopters, but they will remain within the AW101 fleet’s IMOS support framework.
The Navy will take command of the RAF’s Merlin HC3 fleet late in 2014, and both RAF squadrons will formally disband in mid-2015. The Mk4 Phase 1 program to add folding rotors and make basic changes to 7 interim (Mk.4i) helicopters will start immediately, for delivery during 2015-2016. The Sea Kings will retire in 2016, but the full Mk4 Phase 2 helicopters won’t really be ready until 2018.

April 11/11: Thales announces a renewed contract with Lockheed Martin UK for the next phase of IMOS, from 2011-2016. The undisclosed contract continues the availability-based support package for the Merlin Mk1 and Mk2’s acoustic sub-system: the popular, multi-platform Folding Light Acoustic System for Helicopters (FLASH) Active Dipping Sonar, and the parallel sonics sub-system for sonobuoy processing.
Thales will support the fleet by providing service management, supply support, technical support and equipment performance analysis. The will also replace the sonobuoy-related sonics sub-system with a phased introduction of a new Thales acoustic sub-system, including a new common acoustic processor incorporating the latest processing technology. That work will be done under the Merlin Capability Sustainment Programme.
Merlin IMOS, Phase 2
Jan 18/11: Aviation Week reports that in parallel with the Navy’s Merlin Mk.2 program, the UK MoD is planning for upgrades to the RAF’s 28 HC3 and HC3A variants in 4-6 years. Those “Mk.3” plans seem to involve moving them into the Navy, including the addition of the naval version’s folding rotors and tail, tie-downs, and the Mk.2’s cockpit avionics upgrade. The RAF is still fighting to retain the machines, operating them from land or off of ships as needed.
The article adds that full-rate Mk.2 upgrades are slated to start in 2011, reaching up to 10 rotorcraft at one time, with a 9 month modification cycle for each machine. While full-rate production would begin in early 2012, therefore, the 1st production delivery would come near year end.
Although the main focus is life extension, capability upgrades also are being introduced, including new radar modes (such as inverse aperture radar) and improved acoustic processing.
Oct 25/10: Lockheed Martin UK – Integrated Systems and AgustaWestland announce that MCSP01, the first upgraded Royal Navy Merlin Mk2 helicopter, has performed a successful maiden flight at the AgustaWestland facility in Yeovil, UK. It marks the start of an intensive MCSP flight-test program.
Four trials aircraft will be dedicated to test and evaluation of the new aircraft, avionics and mission systems at AgustaWestland’s Yeovil site through to late 2011. The helicopters will then transfer to QinetiQ at Boscombe Down to perform further mission system performance evaluation, and Release to Service trials. Aircraft conversion will be undertaken at AgustaWestland’s Yeovil facility, with full rate production in early 2012. The Merlin Mk2 is scheduled to enter service in 2013, and achieve Full Operational Capability in 2014. Lockheed Martin UK.

Additional Readings & SourcesNote that the helicopters’ original designation was “EH101”. This was shifted to “AW101” in 2007, but the UK has always used designations of “Merlin xxxx”. Future naval designations will be Merlin Mk2 for the naval version, and Merlin Mk4/4A for the Royal Marine Commando version.
Background: HelicoptersPaveway II kits convert standard Mk 80 family free-fall bombs into laser-guided weapons. Each guidance kit consists of a computer control group (CCG) guidance system with a semi-active laser seeker and pneumatically-controlled guidance canards for the front-end of the bomb, plus an air foil group (AFG) on the back end that provides lift and stability. Once a target is designated, laser guidance is more accurate than GPS, but it can be foiled by obscurants like fog, sandstorms, etc.
At the beginning of August 2011, the US government issued a contract worth up to $475 million…
“Paveway” is actually a US government designation for laser-guided bombs, but the term has been the subject of global legal battles between Raytheon and Lockheed Martin, with Raytheon claiming it as a trademark, and Lockheed Martin claiming it as a generic term. A number of courts have ruled in favor of the generic argument.
UpdatesMay 11/18: A cheaper bang Lockheed Martin Missiles and Fire Control is being tapped by the Naval Air Warfare Center Aircraft Division to produce more laser training rounds. The contract modification is part of a multi-year deal, it provides for the production of 7,501 BDU-59F/B LGTR and is valued at over $23 million. In October 2017 the Air Force had selected Lockheed Martin for follow-on production of Paveway II Laser-Guided Bomb Kits for the ninth consecutive year. The Paveway II consists of a computer control group guidance system with a semi-active laser seeker and pneumatically-controlled guidance canards for the front-end of the bomb, plus an air foil group on the back end that provides lift and stability. Once a target is designated, laser guidance is more accurate than GPS, but it can be foiled by obscurants like fog and sandstorms. The BDU-59F/B LGTR is used in tactical employment training and is a cost-effective alternative to expending on operational Laser-Guided Bomb assets. LGTR allows aircrews to practice delivery tactics in a real-mission environment and experience actual weapon characteristics within today’s range limitations. Work will be performed at multiple locations in the US and in Vaudreuil-Dorion, Canada. Work is scheduled for completion by December 2020.
October 30/17: For the ninth consecutive year, Lockheed Martin has been selected by the US Air Force for follow-on production of Paveway II plus Laser-Guided Bomb Kits. Valued at $131 million, the award also includes all available funding for the service’s foreign military sales and replacement kits. Paveway II Plus includes an enhanced guidance package turns free-fall, or dumb bombs, into laser guided weapons through the addition of a nose-mounted laser seeker and fins for guidance. Production is expected to commence in the first quarter of Fiscal year 2018.
April 23/17: An F-35C loaded with the latest F3 software configuration has successfully hit a moving target with a GBU-12 Paveway II laser-guided bomb in what was the munition’s first developmental release from the fighter variant. The successful test was made capable by the inclusion of Lead Point Compute logic in the software which enhances the effectiveness against moving targets, with the objective of reducing pilot workload. This works by delaying the release point of the weapon to ensure the weapon has the available kinematics to guide to and reach the target at its future location. The GBU-12 has now been tested on every variant of the F-35.
July 29/16: A growth in Paveway guided bomb sales has resulted in Raytheon posting better than expected quarterly revenues for 2016. The sales saw the company’s missile division posting a 6% increase in the second quarter. International sales accounted for a third of all guided munitions with half of exports coming from governments in the Middle East and Africa.
May 11/16: Lockheed Martin Missiles and Fire Control and Raytheon Missile Systems have been awarded a combined not-to-exceed $649.7 million modification contract for Paveway II production. The modification provides a five year extension for Paveway II missile production with work completion expected for July 27, 2023. Foreign Military Sales (FMS) of the munition in 2015 included a $1.29 billion sale of muntions to Saudi Arabia, which included 1,000 GBU-12 Paveway II laser guided bombs.
Aug 1/11: Lockheed Martin Corp. in Archbold, PA (FA8213-11-D-0008), and Raytheon Missile Systems of Tucson, AZ (FA8213-11-D-0007) receive a $475 million contract for Paveway II laser-guided bomb computer control groups (seekers), and GBU-12 air foil groups (tail kits) for 500 pound bombs. Both elements are needed, in order to create a GBU-12 laser-guided bomb. The Ogden Air Logistics Center/GHGKA at Hill Air Force Base, UT manages the contract.
Discussions with Hill AFB confirm that this is a single 5-year firm-fixed-price, multiple-award contract. The 2 firms will compete for purchase orders, as the USAF issues them.
In December 2006, France’s Defense Ministry awarded a contract for nuclear-propelled fast attack submarines to state-owned warship builder DCN and nuclear energy group Areva-TA. The contract’s total value could be as high as EUR 8.6 billion, and it is set up as an initial EUR 1.0-1.4 billion contract (reports vary), followed by 6 options (tranches conditionnelles) to cover development expenses, the production of more submarines, and through-life support during their first years of operational service.
All ships wear out over time, and the repeated squeezing and relaxing experienced by submarine hulls make their replacement times less negotiable. The USA began introducing their new-generation NSSN Virginia Class fast attack boats in 2004, and Britain’s problem-plagued SSN Astute Class followed in 2010. Now, it’s France’s turn to renew its SSN fleet, as DCNS works to supply 6 Barracuda Class submarines between 2016-2027.
The Barracuda SSN ProgramThe program’s total value was initially set at EUR 7.9 billion (then $11.13 billion), but has since risen to EUR 8.6 billion ($12.32 billion in 2011). The contract was set up as an initial EUR 1.0-1.4 billion contract (reports vary), followed by 6 options (tranches conditionnelles) to cover production of the other boats, development, and support during their first years of operational service. Subsequent orders have not revealed costs per boat, however, just inferences about creeping overall program costs.
The first Barracuda Class submarine is still expected to enter service in 2017, with the other 4 following every two years (2019, 2021, 2023, 2025) and then the 6th and last boat due to be commissioned in 2026-2027.
Within the DCNS/Areva TA consortium, DCNS will act as the submarine prime contractor, including responsibilities as overall architect, platform and propulsion system prime contractor, systems integrator, nuclear safety studies coordinator and through-life support prime contractor. The Barracuda Class will be built at DCNS’ Cherbourg shipyard.
Areva TA will act as prime contractor for the nuclear powerplant, and NucAreva will take around 15% of the contract’s value. The nuclear propulsion unit, derived from that developed for the “Le Terrible” SSBN nuclear missile submarine, will be supplied by Areva TA under the prime contractorship of the French atomic energy commission (CEA). Other contractors include:
Per the planned dates above, the team has yet to launch a submarine, let alone deliver one. Submarines under construction or on order include:
Other named submarines of class include:
The Barracuda program will meet the French Navy’s operational mission needs by providing replacements for its 6 current-generation nuclear attack submarines. Displacing 5,100-5,300 tonnes submerged, at 99m long and 8.8m in diameter, the new Barracuda Class will be about twice as large as the Rubis Amethyste Class boats they will replace. Indeed, they are roughly the same size as the Royal Navy’s existing SSN Trafalgar Class boats. They are designed to remain smaller than the USA’s new 7,300t Virginia Class SSNs, however, or the new and slightly larger British Astute Class SSNs.
Despite their relatively modest size, the Barracudas will have sharp teeth. A set of 4 x 533mm launch tubes will be able to fire its stored armament of up to 20 heavy weapons, in whatever combination of new short range F21/Artemis heavyweight torpedoes, medium-range SM39 Exocet anti-ship missiles, A3SM (Mica) anti-aircraft missiles, and stealthy long range MdCN Scalp Naval cruise missiles is on hand. The class will also be able to accommodate mines or carry 12 commandos, whose equipment can be carried in a mobile pod attached aft of the sail. One key unanswered question will be the type’s ability to launch and retrieve UUV robots, beyond options that can be launched and recovered via torpedo tube.
A3SM MICAA diving depth of over 350 meters (about 1,150 feet) and a top speed of over 25 knots are both forecast by DCNS. The Barracuda Class’ regular crew level will be 60, and the boats will be designed for operational cruises of up to 70 days, in contrast to the current Rubis Amethyste Class’ 45 days.
As a final advantage, Barracuda’s K15-based nuclear propulsion is designed to offer 2 substantial advantages over existing French boats. The first advantage is that instead of requiring refueling once every 7 years, the new design will extend its time between RCOHs (refuelling and complex overhauls) to 10 years. This translates into higher at-sea availability over the life of each ship. The USA’s Virginia Class, whose reactors aren’t forecast to need refueling over the boat’s expected 30-year life, are significantly ahead in this respect. Nevertheless, the Barracuda’s propulsion will have a second advantage that Virginia Class boats won’t share: it plans to use same nuclear fuel that powers French civilian nuclear power stations. Given France’s significant use of nuclear power, this commonality is expected to drive fuel costs down sharply.
SMX Ocean: A Conventional Export Derivative SMX OceanAt EuroNaval 2014, DCNS unveiled their 4,750t SMX Ocean diesel-electric attack submarine concept. It’s much closer to operational reality than past concepts, as it’s based on the basic Barracuda layout, masts, and combat system.
Switching out the nuclear reactor does create a bit more space, even with 2nd generation fuel cell technology added to give the submarine submerged endurance of 3 weeks. A cable-and-collar “saddle” system can be added for deployment and retrieval of UUVs from a mid-body chamber, and a detachable mobile pod aft of the sail can carry a special forces swimmer delivery vehicle. Behind the UUV bay, a 6-shooter for vertically-launched cruise missiles like MBDA’s MdCN/ Scalp Naval is complemented by internal frontal space for 28 weapons in any combination of heavyweight torpedoes, Exocet anti-ship missiles, A3SM anti-aircraft missiles, or mine packages. Items like the Vipere tethered communications and surveillance buoy round out the package.
Sub advancesThe submarine is touted as a complement for carrier battle groups, but the truth is that their speed requirements tend to stretch the SMX Ocean’s capabilities, which top out at 20 knots and lose efficiency well before that. It would fare rather better as a companion to slower amphibious assault groups, but its real markets may be more specific.
Australia is looking for a long-range fleet of modern submarines, and their push to negotiate directly with the Japanese for the 4,000t+ Soryu Class may be forced toward competitive bids for political reasons. Meanwhile, India has just approved a “Project 75i” program to add 6 locally-built submarines beyond their forthcoming Scorpene fleet. A relationship extension based around Barracuda hulls would build on already-proven industrial relationships and training, and allow for excellent weapons commonality with the Scorpene fleet. It would also complement both the scope of India’s maritime interests, and local work fielding and refining their own nuclear submarine design.

SSN Barracuda conceptMay 10/18: One more for Paris The French government will buy a fifth Barracuda class nuclear attack submarine. A spokesperson for the Armed Forces Ministry confirmed in a statement that the Defense Minister Florence Parly made the decision on May 2nd. The draft multiyear budget that is set to run from 2019-2025 includes the funding for six Barracuda class submarines, delivery of which is scheduled for 2025. The Barracuda SSN program started in 2006 when France’s Defense Ministry awarded a contract for nuclear-propelled fast attack submarines to state-owned warship builder DCN and nuclear energy group Areva-TA. The Barracuda program will meet the French Navy’s operational mission needs by providing replacements for its 6 current Rubis Amethyste class nuclear attack submarines. The Barracuda’s are roughly the same size as the Royal Navy’s existing SSN Trafalgar Class boats, and twice the size of the current vessels. The program’s total value was initially set at then $11.13 billion but has since risen to over $12.32 billion.
Feb 11/15: Interview with program manager.
Navy Recognition managed to get the Barracuda product manager to answer a few questions in a brief interview. Expected improvements anticipated over the Rubis class: maneuverability, stealth, detection capabilities.
Oct 28/14: SSK Ocean. DCNS unveils its 4,750t SMX Ocean concept design at EuroNaval 2014. This diesel-electric attack submarine design is much closer to reality than past SMX concepts, because it’s based on the basic Barracuda layout, masts, and combat system. Meanwhile, shifts in the global market toward the Pacific and Indian oceans are tilting requirements in favor of larger conventional submarines, with more range and endurance. See above for details.

June 8/11: Weapons. The DGA holds a test launch of the SCALP Naval / MdCN (Missile de Croisière Naval) at its Ile du Levant missile test center in the Mediterranean, using an underwater platform simulating the launch conditions on the future Barracuda SSN. The change from water to air, and subsequent launch/flight, is one of the most difficult and important steps for any such missile. When fully operational, the Storm Shadow’s MdCN cousin is expected to offer a stealthy sub-sonic strike missile with long reach: over 1,000 km/ 540 nautical miles.
When combined with a successful 2010 vertical-launch test from an above-water platform, MBDA believes that its SCALP/MdCN program is now synchronized with the planned entry into service of the FREMM frigate (2014) and Barracuda submarine (2017) platforms.

March 18/11: #2. DCNS announces that the 1st hull section of the 2nd boat of class has left the prefabrication hall at Cherbourg on schedule. Duguay-Trouin’s aft section #7 is just 1 of about 20 hull sections and 4 “interface points.” The 40t hull section is made of steel alloy, and measures about 9 meters in diameter by 4 meters. It will sit immediately behind the nuclear reactor compartment, and will eventually contain the submarine’s electrical distribution plant.
DCNS adds that construction of the 1st-in-class Suffren in also on schedule in Cherbourg, with the first equipment integration phases set to begin in the next few months.

Scalp NavalOct 27/09: Colfax Corp. announces that its Colfax-Imo Pompes Business Unit in France will provide oil pumps and other fluid-handling systems for France’s Barracuda class nuclear submarines. They will deliver the first pumping systems to DCNS in late 2010 – early 2011. Colfax will continue to provide service, training, parts and documentation for its systems during the service life of the vessels. Daniel Joslin, managing director of Colfax’s business in Tours, France:
“Submarines need to operate as quietly as possible to avoid detection, and the French Navy accordingly specified its pumps should produce low noise levels and vibrations… Our Colfax Defense Centre of Excellence in Tours [DID: one of 3, located in Tours, Mumbai, and Warren, MA] has the staff and equipment capable of meeting those demanding requirements to ensure the pumps provide years of quiet, reliable service.”
June 26/09: #2 ordered. The French DGA procurement agency orders the 2nd Barracuda class boat Duguay-Trouin from DCNS and Areva-TA. At present, the DGA is forecasting EUR 7.9 billion for the total Barracuda program, and 2028 as the program’s finish date.
The same day saw assembly of the lead boat, Suffren, begin, with the welding of the first 2 aft hull sections. DGA release [in French].

April 3/08: Sub-contractors. What does the International Space Station have in common with a nuclear submarine? Both are enclosed environments that must provide breathable air, which includes removing carbon dioxide as well as replacing used oxygen. Both also have very tight space limitations, and power limitations as well since the life support systems must be the last system to fail.
EADS Astrium in Friedrichshafen, Germany developed a binding carbon dioxide (CO2) regenerative process for the International Space Station’s European Columbus lab module, which was docked on Feb 10/08. Now DCNS in Cherbourg, France has ended a 4-year competition among established naval firms by awarding the life support contract to… the space firm EADS Astrium. EADS release.
Jan 25/08: Sub-contractors. GE Oil & Gas announces that their Thermodyn subsidiary in Le Creusot has been selected to provide the turbo-generators and propulsion turbines for the French Navy’s 6 new Barracuda Class nuclear fast attack submarines. The DCNS award continues Termodyn’s history if supplying such systems for France’s nuclear submarines, and for the nuclear-powered Charles de Gaulle aircraft carrier as well.
The contract covers 2 turbo-generators and 1 propulsion turbine for the first-of-class FNS Suffren, which is scheduled to enter service in 2016, as well as for each of the other 5 boats ordered under optional contracts. GE’s propulsion turbine drives the propeller, and supplies the required mechanical power to the submarine when at top speed. The 2 turbo-generator-rectifiers supply electric power to the propulsion and auxiliary systems, keeping the sub’s electronics powered and allowing quieter slower speed movement. GE’s project partner Jeumont Electric is supplying the generator-rectifier equipment for the turbo-generators, and this first set of turbo-generators and propulsion turbine is scheduled for delivery between October 2010 – February 2011.
As noted above, Areva TA is the prime contractor for the shipboard nuclear power plant, which powers Thermodyn’s systems and thus the submarine. A submarine’s need for stealth means that these Thermodyn condensing-type turbines are highly customized to fit a submarine’s small space, while ensuring very low noise and vibration levels. The Le Creusot facility even operates a special anechoic chamber to test the equipment’s noise levels prior to delivery. GE also will provide assistance in the packaging of its equipment within the propulsion main frame, and in site tests. GE release.
Sept 6/07: Sub-contractors. SAFRAN Group subsidiary Sagem Defense Securite has won a competitively-bid contract from DCNS as prime contractor for the surface detection system (DAS) on France’s future Barracuda class nuclear submarines. The surface detection system for Barracuda class submarines comprises a radar mast and two optronic masts, which integrate a passive electromagnetic detection sensor. The optronic sensors of the system will provide day/night surveillance, detection, tracking and sighting functions.
A value was not announced, but the contract does includes a firm order for the first submarine in the series (FNS Suffren), as well as conditional orders for following vessels. Sagem will deliver the first system to DCNS in 2010. Sagem Defense Securite release.
June 1/07: Named. The ships of the Barracuda Class has been officially named by the French Ministry of Defence. The first-of-class will be the Suffren. It will be followed by the Duguay-Troin, Dupetit-Thouars, Duquesne, Tourville and finally the De Grasse.
Construction will begin in the summer of 2007. French Navy release [en Francais].
