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

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

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.
