History
Planning and construction
The ships of the Karel Doorman - class were planned in 1977 as a replacement for the outdated, still originating from the Second World War anti-submarine ships of Roofdier class ( predator class). The Dutch navy put greater emphasis on survivability, so the ships should receive a reduced radar, acoustic and infrared signature. In 1984 it also became clear that the frigates Van Speijk class needed a contemporary replacement so it was decided to equip the new frigates with both air defense as well as anti-submarine capabilities. The first ship of the class, the Karel Doorman was laid on February 26, 1985 at Royal Schelde in Vlissingen at Kiel, the launching ceremony was held on April 20, 1988, the commissioning on May 31 place in 1991. The remaining seven ships of the class were followed until 1995.
1997, all ships were equipped with better navigation radars of the type Scout Thales Nederlands.
Sale
Due to their versatility were interested early on other nations for the frigates. After long negotiations in 2004 two ships were sold to the Navy of Chile. They were put into service in 2005. 2005 went two frigates together for 296.6 million U.S. dollars to the Navy of Belgium. The ships are in use since 2007. In May 2006, Portugal was first interested in buying two ships to replace the two outdated ships of João Belo class. The contract, worth 240 million euros came in November of the same year, in early 2009 and 2010, the ships were handed over to the Portuguese Navy. The second ship finally met on 9 March 2010 for the first time in its new home port.
Technology
Hull and drive
The frigates of the Karel Doorman - class is 122.25 meters long, 14.4 meters wide and with a maximum displacement of 3320 tons with a draft of 6.05 meters. The drive, a CODOG system consists of two Stork - Wartsila 12SW280 diesel engines with 4900 hp for cruise journeys up to 21 knots and two Rolls- Royce Spey SM1C gas turbines of 17,000 hp, which accelerate the ships at their top speed of 30 knots. The range is 5000 nautical miles at 19 knots.
Armament and Electronics
Main armament of the ships is a 16 -cell Vertical Launching System Mark 49 for RIM -7 Sea Sparrow anti-aircraft missiles and two quadruple launcher for AGM -84 Harpoon anti-ship missiles. Against sea and air targets and the 76 -mm gun Oto Melara of on the foredeck can be used. As a defense of approaching missiles, aircraft and small sea targets approaching a Goalkeeper short-range defense system is installed on the astern structures. Against U- boats may be on the one stationed on the quarterdeck Westland Lynx helicopters and the other Mk -46 torpedoes, which can be expelled from four torpedo tubes, are used.
The battlefield reconnaissance carried out by a LW - 08 long-range air surveillance radar, a SMART -S 3D-Seeraumüberwachungs-/Feuerleitradar and a PHS -36- Bugsonar. The ships also have a Thomson Marconi (now Thales ) Anaconda DSBV 61- tow sonar. A Scout LPI radar navigation supports navigation at sea. The data processing is done by the Signaal SEWACO VII System with Link 11 data link and satellite communications. The fire control data is passed on to two Signaal STIR fire control radars.
Modernization
The Belgian Navy component first was between 2008 and 2010 at the Women shipyard in Vlissingen, the Louise -Marie, and then rebuild the Leopold I with regard to the future use of the NH -90 helicopters aboard. The flight deck was strengthened and extended by 1.4 m, so that the area is enlarged from 82.62 sqm to 90.18 sqm. The hangar was also extended to 1.50 and increased the gates by 80 cm. An operating system from Rexroth was still scaffolded.
The Dutch navy will modernize between September 2010 and early 2014 in Den Helder, the four remaining units of the two Benelux States. This modernization includes both hardware and software changes. The get a new Mastkonfiguartion with a Thales Seastar surface search and surveillance radar (X -band), a Smart -S Mk F- 1 3D air and surface search radar (F -band) and a STIR fire control radar ( I-/J-/K- band). In addition, the scaffolding of a gatekeeper comes elektro-optischen/infra-rot (EO / IR) 360 ° surface search and surveillance system.
The conversion of the first ship Zr. Ms. Van Speijk should be completed by June 2012. The reconstruction phase of the remaining three units will be shorter. Leopold I should be in the end of 2012 again available. The Zr. Ms. Van Amstel and Louise -Marie each follow at a distance of good one year.
Under this program, the two Dutch frigates obtain the necessary information regarding the NH -90 operating modifications. The Dutch ships get a few more upgrades, including a new low-frequency active and passive sonar is provided.
