When you think of conventional submarines, you think of batteries and diesel engines. However, that might change completely. Naval architect Sven Los from Nevesbu presented a new concept: the electric submarine. Without diesel engines. A submarine revolution?

Ever since the early days of modern submarines, some 120 years ago, conventional submarines have been sailing on batteries that can be recharged at any time with the help of onboard fuel generators. That concept has barely changed, despite all technological developments. Yes, thanks to the snorting mast, a submarine can also stay submerged during charging, and air-independent propulsion (AIP) has created a small revolution. Because of AIP, next to diesel generators and batteries, submarines can stay submerged even longer.

The next step might have much more impact. If the diesel engines are removed from the submarines and many more batteries are installed, Sven Los believes this will result in a less complicated design, less maintenance, a smaller crew, less chance of detection and lower costs (in acquisition and operation).

On board of a classic diesel-electric submarine, depending on its size, there are two to four diesel generators plus systems such as a snorting mast, tanks for fuel, an exhaust gas system and many pipelines to connect all these parts. This takes up space and requires maintenance both at sea and on shore. In addition, certain parts, such as valves, are sensitive. The diesel generators and the snorting mast also provide an increased risk of fire and leakage. This is why there is a lot of technical staff on a submarine.

Graduation project

Jaime Karremann from Naviesworldwide.com/ Marineschepen.nl spoke to Sven Los at the IV-Group’s office in Papendrecht (the Netherlands), an organisation of which the maritime engineering firm Nevesbu has been a part since 2004. Nevesbu was founded in 1934 and, together with the Dutch navy, took care of the designs of various cruisers, destroyers, frigates and submarines. Nevesbu was involved in the design of all Dutch submarines since 1945 andthe Hai Lung class submarines of Taiwan. Nevesbu also contributed to various foreign designs and to the upkeep programme of the Walrus-class. As a subsidiary of the former Dutch shipyard RDM, it also designed the export submarine Moray.

However, the agency is also constantly researching opportunities to innovate. When Sven Los started his graduation project at Nevesbu in 2017, he was given the assignment to conduct research into fully electric submarines.

Los: “A graduate before me had made a very nice model of a submarine’s propulsion system and he compared different configurations, such as diesel-electric with lead-acid batteries and diesel-electric with lithium-ion batteries. Those resulted in great improvements which made people at Nevesbu think about 100% electric submarines. ”

Los focused on today’s technology. The current submarines still use lead-acid batteries, but smartphones, laptops and electric cars use lithium batteries. Los: “Lithium batteries have undergone major developments in recent years. They have an enormous energy density, which makes electric sailing a realistic possibility.”

Soon, it turned out that the profits could be huge, but to figure out the exact impact, Los simulated the concept in a propulsion model to answer the following question: “What could you do with an electric submarine and could it be interesting for certain navies?”

 

Moray ad

The Moray was a concept submarine that was designed by Nevesbu in the 1980s on the basis of the Walrus and Zwaardvis class and had to be sold by RDM. Until the beginning of the year 2000, RDM unsuccessfully tried to offer the different versions (1100, 1400 and 1800) to Indonesia, Thailand and Egypt, among others. This advertisement dates from 2001. (Image: RDM)

 

Interest from abroad

Although the idea of an electric submarine seems to be fairly simple, it is unique. In any case, nothing has ever been published about it. In June 2018, Los presented his research results during the submarine symposium UDT in Glasgow, where there was a lot of interest in his project. Los: “Everyone was enthusiastic, especially because it is a very different way of thinking. People often only think of two kinds of propulsion: diesel-electric or nuclear, and my research was an eye-opener. Many people saw that fully electric submarines could have many advantages.”

However, the electric submarine is still something for the future. “The battery technology is fairly new and the capacity is not sufficient just yet. But, you have to work on it now in order to be able to implement it in twenty years. If you look at how much the capacity of batteries has improved over the past ten years, then this must be a realistic design.”

E-Moray 1800

Los’s design is based on the Moray. This submarine was developed by Nevesbu in the 1980s to be sold by RDM.

Los changed the Moray 1800 (of about 1800 tons, comparable to the French Scorpène, the German Type 212A and the Swedish A26) into a fully electric submarine. “Because Nevesbu designed the Moray, there’s a lot of information about it.I’ve changed the design so I can put in as many batteries as possible . I did not make the submarine smaller, I just used the space in a different way. The dimensions of the submarine have stayed the same, so I could make a comparison.”

The result is an electric Moray-1800 without engine room, snorting mast, fuel tanks, fuel pipes and all kinds of other equipment. The accommodation has been moved backwards and a lot of batteries have been added.

Electric submarine in Baltic

The electric concept submarine can go round the Baltic Sea under water, which is a distance of about 3500 km. A diesel-electric version would have to snort after about 550 km. (Source: Nevesbu)

 

Submerged for one month

The result is amazing. Los: “A diesel-electric submarine can stay submerged for a few days and then cover 300 nautical miles. The electric variant can stay under water for 25 to 30 days and sail 2,500 nautical miles underwater.”

That means the electric submarine can sail around the Baltic Sea while submerged.

The electric version loses against a diesel-electric variant as soon as it starts snorting or surfaces and starts its diesel engines. “From then on, a diesel-electric boat has a range four to five times as large as an electric version.”

However, the question is whether it is necessary for a lot of navies to have a submarine that can sail long distances. “You have to ask yourself in a very early stage, what you want to do with such a submarine. The Swedish SSK’s, for example, mainly sail submerged in the Baltic Sea and I have heard that those submarines are only away for short periods of time; days or maybe two weeks.”

“For such profiles, a design like this is very interesting, because the Swedish submarines almost immediately enter their patrol area. Dutch submarines first have to transit long distances.” For example, in the past, Dutch submarines have been operating mainly in the Norwegian Sea, Mediterranean Sea and even in the Indian Ocean and Persian Gulf. Like their Canadian and Australian counterparts, they are weeks or months away on a deployment.

Just stay submerged

Conventional submarines quite often sail surfaced during long transits. “Of course, you can still do that with an electric submarine, but it will not have any benefits. The drag is generally much higher. So, an electric submarine will submerge as soon as possible and will surface only in emergency situations or for a barbecue. ”

Long periods of submerged sailing also have consequences for the air quality, which rapidly deteriorates. “You have to look at submarines with AIP or nuclear boats that have been under water for some time. The biggest difference with nuclear submarines, however, is that thanks to the nuclear powerplant you have a lot of energy at your disposal, so you can get oxygen from sea water. For electric submarines, I would consider a tank of liquid oxygen.”

Snorting submarine

Stealth submarine

Diesel-electric submarines regularly have to recharge their batteries. The least noticeable option to do that is sailing at periscope depth, putting the snorting mast out of the water and starting the diesel engines. But, a snorting submarine can be detected in several ways: the diesel engines make a lot of noise, the submarine sails just below the surface of the water and can be seen in clear water with the naked eye or with magnetic sensors, the diesel engines produce a lot of heat, and the masts can be seen by radar.

A submarine that does not have to snort has a huge advantage, as we have seen with nuclear submarines. But there is more, Los discovered: “To start with, an electric submarine doesn’t have the extreme signatures of snorting, and in addition it does not have any fuel on board, so you need fewer valves and pumps.” These valves and pumps produce noise when fuel from a tank is used and the weight of the boat has to be corrected. The electric submarine is therefore also quieter when submerged than a diesel-electric submarine.

 

In Deepest Secrecy
In Deepest Secrecy: Dutch Submarine Espionage Operations from 1968 to 1991

As the book In deepest secrecy shows, during a patrol, diesel-electric submarines leave their patrol area before they start snorting. To go to that snorting position, they first have to transit for a while and when they are not in their patrol area they might miss crucial intelligence. An electric submarine can stay in its patrol area for much longer.

Less work, less maintenance, less crew, less recruitment, less costs

Half of the crew of diesel-electric submarines are technicians, and the majority is involved with the propulsion. Removing the diesel engines results in an enormous reduction in staff. Originally, it was planned that the Moray 1800 would need 34 crew members . Sven Los: “The number of people needed for maintaining and controlling technical systems will be reduced. There is no need for surveillance in the engine room, there is no snorting mast that might take in water accidentally. With less systems, there is less chance things break down. Especially if you also replace the hydraulic systems with electrics. That means a huge reduction in hydraulic systems and pipelines. That way, you can leave out a lot of mechanical systems. Less energy is needed and there is less work to be done. Maintenance for the lithium batteries is not needed, you might even not do any maintenance. The only thing that still requires maintenance are small pumps.”

 

“I expect that it is possible to reduce the size of the crew, depending on the requirements and automation on board, to 18 to 20 people.” This obviously saves costs (salary, training, etc.) and the recruitment department doesn’t have exert itself to recruit technicians.

Less crew; risk in case of fire?

Continuously reducing the number of crew members is obviously interesting to limit costs, but is not it more dangerous in the event of a fire? Sven Los does not think so. “I often hear that crew reduction is a risk when there is a fire on a submarine, but a huge risk is taken away by removing the diesel generator set. Most of the fires start there: it is warm, there are rotating parts, oil, exhaust fumes. The battery compartment is much more manageable and these are also compartments you can shut off. Plus, in case of a fire in the battery compartment, I would not send people in to extinguish it. ”

Safety of lithium batteries

During his research, Los first investigated the available battery technologies and looked at which would be best applicable for submarines. Lithium batteries turned out to be the best.

The advantages of lithium batteries compared to those of lead-acid batteries are, for example, that lithium batteries are much smaller. A submarine with lithium batteries can also sail longer.

Lithium batteries, however, are known for their risk of fire. There are lots of stories about exploding smartphone batteries or burning electric cars. “That’s a risk,” Los acknowledges, “but it also applies to lead-acid batteries, which produce hydrogen gas during loading or unloading. That means there is a risk of an explosion, which is not the case with lithium batteries. Those batteries might catch fire. The downside is that these batteries are small and installed in packs, so if one battery catches fire, there might be a chain reaction. ”

However, many of the incidents involving lithium batteries involve cheap batteries of poor design. Large battery manufacturers such as Panasonic and Kokam are working on special submarine batteries and pay a lot of attention to safety mechanisms for these batteries. Los: “These safety measures are already built in at cellular level. They are also developing cells that are resistant to external heat sources and prevent a chain reaction. Also, other cells can be automatically switched off and cooled as soon as the battery becomes overloaded.”

Hence, the effect of fire in one battery becomes minimal, because there are a lot of cells, explains Los. There is no need for a separate backup according to him, because “they are all backups”. If batteries are damaged by fire or something else, there is enough spare capacity.

And shock? The shock requirements on submarines are strict. That should not be a problem according to Los. “If you drop your phone, your screen might be shattered, but the battery will still work. Besides, some manufacturers say they meet the shock standards for submarines of certain navies.”

 

Charging at sea

An electric submarine cannot charge its batteries itself. Recharging has to be done in port, but that can be done in quite a short time, says Los. The batteries of his concept submarine can be charged in 16 hours, at its fastest.

The submarine does not even have to go to its home port or a naval base. Recharging is possible almost everywhere. “You do need a certain voltage and the connection must be suitable, but it is relatively simple. All major ports have shore power connection and the submarine has to be designed in such a way that the batteries can be recharged in a civilian port. That might take a bit longer, but it does not directly affect the readiness of the submarine. ”

In the researcher’s view, it is also possible to order a diesel generator and recharge the batteries that way.

That already provides more flexibility, but Nevesbu has continued to think outside the box for solutions . “We have also talked about charging via a support ship. The submarine can sail next to a replenishment ship that uses its diesel engines to transfer energy. I don’t know if any navy could be interested, but it certainly is possible. ” Many countries have submarine support vessels, so the concept of charging at sea might be relatively easy to apply for them.

Nevesbu’s search for more solutions did not end with charging at sea. “You can come up with all kinds of futuristic ideas, such as submerged charging stations or a floating wind farm with tapping points for submarines. But that is more 007-style,” Los admits. “Technically it could be possible, but whether it is realistic, is something else.”

 

For whom?

Back to reality. The technique is not ready yet to be appliedto submarines used for operations thousands of nautical miles from home. InLos’s view, the electric submarines are especially suitable for countries that now want to operate close to home with smaller submarines. Countries such as Germany, Sweden, but also Greece, Singapore and Indonesia, for example.

There is, however, another interesting market: countries that do want submarines, but find them too expensive and / or too complex. They can not only purchase these submarines, but also design and build them themselves.

Although the concept is about the propulsion, electric submarines are easier to design and much cheaper to build. “The number of pipes in a submarine is huge. An electric submarine has far fewer systems to integrate; there are hardly any tanks left, much fewer pipelines and pressure hull penetrations. Pressure hull penetrations add to the complexity during the building phase, because they weaken the construction. The snorting mast and the system for exhaust gases are quite complex as well, and you do not need them anymore. If the number of systems reduces, you will have fewer interfacesand thereforeless chance of things going wrong.Also, lithium batteries do not need cooling and do not need to be designed and built, you just need more cables.”

“So, the use of electric submarines is easy, less maintenance is needed and there are fewer things that can break down at sea, especially if you compare themto boats that have the same submerged endurance, for example AIP submarines. An integrated AIP system is only suited for specialised technicians and there aren’t a lot of them. Especially countries that are new to submarines run into problems due to insufficient knowledge and experience.”

Sven Los expects electric submarines to be cheaper, because they need less maintenance. As a result, they will also be available more often. “Pipelines, the snorting mast, the exhaust gas system and auxiliary systems will take the most time during maintenance. I’m not an expert on submarine maintenance, but someone at Nevesbu, who is familiar with the Walrus class, said that maintenance costs would be reduced by 50%.”

Might these types of submarines in the future also be interesting for countries that operate thousands of miles from their home port with conventional submarines? Like Canada, the Netherlands and Australia? Los: “It depends on the development of battery capacity. The past decade, battery capacity has improved by 60%. If you add another 60% in the next decade, a lot of possibilities will open up. But still, a lot has to happen before the energy density of batteries comes even near the energy density of diesel. If they want a conventional submarine to cross the ocean, I do not think it will be a battery-only submarine. I expect in that case AIP is needed. ”

That is why Nevesbu is currently researching a concept of batteries and AIP.

Will electric submarines cause a revolution within the submarine world? It is likely, but as usual, it does not only depend on technological development, but also on the courage of admirals to move in that direction.

For the time being no exercise with SM-2 missiles

17 - 09 - 2018 / Navy News / 0 comments

All SM-2 missiles of the same type as the one that caught fire in June 2018 are currently not allowed to be used for exercises. During a launch by the German frigate FGS Sachsen, an SM-2 Block IIIA missile burnt down while it was still in the VLS. Since then, research has been carried out  to determine the cause, and until that is completed, no exercise launches are done. This was reported by the German Ministry of Defence to Naviesworldwide.com.

On June 21, 2018, the German Navy had a live fire exercise with two frigates near Norway. The SM-2 missile of the F124 class frigate FGS Sachsen burnt down. This caused major damage to the VLS and the bridge of the ship.

As claimed by a spokesperson for the German Ministry of Defence, the engine burnt. The SM-2 has a dual-thrust solid propellant engine. This Mk 104 Dual Thrust Rocket Motor from Aerojet Rocketdyne has two types of fuel. The first part of the fuel provides an enormous amount of energy and acceleration, causing the missile to leave the launcher. Next, the fuel meant for the flight towards the target is burnt. Other missiles such as the SM-3 or Harpoon have a separate booster, which is dropped after launch.

Immediately after the accident, an investigation was launched to find out the cause. When it will be completed is not yet known. In any case, the German MOD does not expect this to happen in the coming weeks.

Until the research has ended, no SM-2 missiles will be launched for exercise. “For safety reasons, all missiles of this type were initially blocked, which they are still,” said the German MOD’s spokesperson. Earlier, the Dutch MOD had already reported that no SM-2 Block IIIA would be launched by the Netherlands while the investigation is going on.

The SM-2 Block IIIA is used by the United States, Japan, Australia, the Netherlands, Germany and South Korea. However, there are sometimes differences in electronics. Denmark is currently ordering the missile.

For the time being, these restrictions have no consequences for the Dutch and German navies. No launches of SM-2s are foreseen until the second quarter of 2019.

The launch restriction only applies to exercises. The missiles will be launched in combat situations.

Incidents with the SM-2 are rare. However, in June 2015, an SM-2 missile exploded after being launched by USS The Sullivans.  As claimed by the Dutch Ministry of Defence, the cause was a defect in the rocket engine. This missile was the same type as the German SM-2, but from an older production series. After the investigation of the incident, there was contact with the navies who use the SM-2 missile “about the cause of the incident and measures to prevent recurrence”, thus the Dutch MOD. They also wrote that “the US Navy has set a maximum life for a particular part of the missile. Part of the Dutch missiles has not yet exceeded this lifetime.”

All parties are now waiting for the results of this research. It is to be expected that in the future, users will again be informed of the outcome and any measures taken.

HNLMS Rotterdam halfway in midlife update

Last Saturday, HNLMS Rotterdam left Amsterdam after six months of maintenance and modernization The Dutch LPD is halfway through the midlife update, the rest of the program will be completed in Den Helder.

In February 2018, HNLMS Rotterdam arrived in Amsterdam at Damen Shiprepair. This location was chosen because the 166-meter-long ship is too big for the docks in Den Helder. Much work has been done on the ship in Amsterdam: the propeller shafts were removed and maintained, pipelines were replaced, a ballast water cleaning system was added, the ship was painted, new cables were laid, and two new masts were installed.

For the modernization, both the opsroom and the amphibious command centre have been cleared and converted. These have been merged into one and the rooms have been provided with new equipment.

An important milestone in the modernization process will be the placement of the Thales NS106 radar, which replaces the old DA08 radar, in September.. The NS106 radar is an AESA radar, a variant on the NS100 that is also used by the Singapore Navy. In addition to that, the Rotterdam also receives the Thales Gatekeeper, an HD camera system. One camera is placed under the bridge, three others to the rear and side. This way, a 360-degree view can continuously be provided.

On Saturday, September 1st , the Rotterdam was towed to Den Helder, where the project is being continued. The platform is expected to be ready by December and modernization will be completed by the end of March 2019.

More details emerge in future Dutch submarine programme

13 - 06 - 2018 / Navy News / 0 comments

Recently French shipbuilder Naval Group and the Swedish-Dutch combination Saab-Damen released more information about their proposals for the Dutch Walrus class replacement.

Barracuda

Naval Group plans to offer the Dutch Defence Materiel Organisation (DMO) a design based on the new nuclear submarine Barracuda, Naviesworldwide.com learnt during a visit in Cherbourg, France . This SSN is currently built by Naval Group in Cherbourg.

Naval Group was successful with another Barracuda derivative, the Shortfin Barracuda, in a tender for the Australian navy. Now Naval Group has designed another conventional submarine, this time for The Netherlands.

There are no details known about the French offer, but Naval Group’s choice to offer a design based on the Barracuda, means that they have a large submarine in mind. Presumably larger than the 2,000 ton Scorpene. The five French submarines of the Barracuda class have a subsurface displacement of 5,300 tons, much more than the Walrus class which boast a mere 2,800 tons.

The French submarines have a length of 99.5 metre. The design for The Netherlands is expected to be much shorter.

A26 based

Also Saab and Damen offer a design based on a submarine which is currently being built: the A26.

Naviesworldwide.com learnt during a recent visit to Malmö and Karlskrona more details. Saab and Damen designed a submarine with a displacement of 2,900 tons, a length of 73 metres and a diameter of 8 metres.

While the 5,300 tons Barracuda has only 4 torpedo tubes (and no VLS), the Saab-Damen offer has six of them plus a Multi Mission Lock. This additional tube has a diameter of 1,5 and is meant for all kinds of large and small drones, and for up to six divers or special forces including equipment.

The submarine’s fore ends is designed as a multifunctional area, where of course torpedoes and missiles can be stowed but also drones. However, the area -not quite spaciouis on the current Walrus class- can also be used as a Special Forces command centre or as a briefing room.

Like the A26 this design includes a Stirling AIP-motor. The Stirling uses ordinary diesel and liquid oxygen. Both are available in ports and also liquid oxygen can be loaded quickly. The engine is a combustion engine, but there are no explosions in place like a petrol or diesel engine. Instead, the engine works with a gas that expands by heat (the combustion) and shrinks again later by cooling. The engine is very quiet due to the absence of explosions. Moreover, the Stirling engine hardly vibrates. Naviesworldwide.com has seen a running Stirling engine which is meant for the first A26, with a coin standing on its side.

To reduce heat and vibrations in the engine room all engines have a casing.

Programme

Apart from Naval Group and Saab-Damen, TKMS (Germany) and Navantia (Spain) also offered designs to DMO. At the end of the year two companies will be chosen to go on to the next stage. In 2021 a contract with one of the competitors will be signed.

Dutch Defence White Paper 2018

12 - 04 - 2018 / Navy News / 0 comments

Author: Jaime Karremann

In March, the Dutch Minister of Defence, Ank Bijleveld, presented the Defence White Paper. The future of the Dutch armed forces was presented in a fairly concise document. The Royal Netherlands Navy has – now hopefully finally – been given the green light again for replacement, although the Defence White Paper does not provide space for the much-needed expansion of the fleet.

A new start

The Defence White Paper 2018 has given the green light again for the navy’s replacement projects. In the coming years, 6.4 billion euros will be invested in navy projects. First and foremost this entails the replacement of the two Dutch M-class frigates, the six Alkmaar class minehunters (Tripartite) and the four Walrus class submarines. The frigates and submarines entered service in the early nineties, the minehunters in the eighties. The replacement programmes have already started.

Aside from those three large projects, there is also room for several smaller projects, such as the acquisition of a new Close-In Weapon System (CIWS), a new Surface-to-Surface Missile (SSM) and a new gun for the Air Defence and Command Frigates (LCF). The recently announced Combat Support Ship, in effect a late replacement of HNLMS Amsterdam, was not mentioned in the Defence White Paper, but is included in the plans.

In the A-letter of the submarine replacement programme (large Dutch projects have to go through several phases from A to E in the Defence Materiel Process, or DMP) for replacement, options were mentioned: replacement by unmanned submarines, by ‘homeland security submarines’, oceangoing submarines, or by all other means except submarines. The first and last option have been cancelled have been cancelled, as proclaimed in the Defence White Paper: “We are replacing the submarines with manned submarine capacity. Research from TNO has shown that variants other than manned submarines cannot meet the needs (and are very expensive). These variants will therefore not be researched further in the DMP B phase and we will send the DMP B letter this year.”

In addition, Bijleveld mentioned something about the future of the LCFs in the White Paper: “The LC frigates are currently undergoing a modernization programme, and in a few years, the requirements to replace these frigates will be drawn up.”

In 2013, the Minister of Defence at the time, Jeanine Hennis decided to close several locations. Bijleveld announced that the Dutch will close fewer locations than planned. The naval Joost Dourlein barracks on Texel will stay open. This location is used for amphibious training by the Royal Netherlands Marines Corps and during initial training of sailors and midshipmen.

Without positive news about the replacements, an expansion of the Royal Netherlands Navy (which currently has six frigates) is still far off with the small budget increase of 1.5 billion Euros. Although Bijleveld wrote in the Defence White Paper that the armed forces are increasingly needed, The Netherlands will not spend more than 1.29% of their GDP in the coming years.

In addition, with the new investments, the cutbacks on sailing and exercise days have to come to an end and the backlogs in spare parts are quickly eliminated.

In Annex IV of the Defence White Paper, in addition to the three replacement programmes currently worked on, future replacement programmes are also mentioned:

  • replacement of Kinsbergen (25-100 million): in 2025
  • replacement of HNLMS Mercuur & Hydrographische Recording Vessels (HOVs) (25-100 million): from 2026
  • replacement of Port Discharge vessels (25-100 million): from 2027
  • replacement of LCFs (over € 2.5 billion): from 2029
  • replacement of HNLMS Pelican (Support ship Caribbean) in 2030
  • replacement of HNLMS Rotterdam (250 to 1000 million): from 2030
  • replacement of HNLMS Johan de Witt (500 to 1000 million): from 2032

Convince

When Bijleveld became Minister of Defence at the end of October 2017, it became clear her department would receive 1.5 billion euros. The plans were already there, but Bijleveld first wanted to do additional research and draft a formal White Paper, partly under pressure from the Ministry of Finance, not a big supporter of defence investments in recent years.

The Defence White Paper meant delay again, but the Minister needed that time to make sure all parties in The Hague were one the same page.

One of the big differences between the original plans and the new ones the original plans is that there is much more space financially for personnel. The Defence organization has been struggling for years in the field of recruitment and retention and Bijleveld wants to invest in it again. She also plans to make the personnel system more flexible.

The minister has also reserved extra money for cyber and IT.

Future for the navy

With the Defence White Paper 2018, the Ministry is taking an important and unique step towards replacing the fleet. The Royal Netherlands Navy will have to replace 23 ships in the next two decades, and for the first time the Ministry of Defence has included the renewal of the fleet in a public plan. With this plan, for the first time since the early nineties, the navy can look forward with some confidence.
