Editing Karel Doorman-class frigate (section)

== Design history ==
In the 1970s, Dutch naval authorities deemed the {{sclass2|Roofdier|frigate|1}}s old, outdated, and therefore in need of replacement. This led to the construction of the ''Karel Doorman''-class frigates in the mid 1980s after the Dutch navy had finalised the design and requirements for the frigates at the end of the 1970s and early 1980s.<ref>{{cite web|url=https://marineschepen.nl/kosten-onderzeeboten.html |title=Hoeveel kost de Onderzeedienst? |publisher=marineschepen.nl |date=2013-03-15|language=nl|access-date=2018-03-18}}</ref>

The design of the class was made in-house at the [[Royal Netherlands Navy]], in close collaboration with construction site De Schelde in Vlissingen and design agency Nevesbu. For the first time [[stealth technology]] was used in the design, such as the sloping walls of the [[Bridge (nautical)|bridge]] section. Much attention was also paid to the care and facilities for the crew, with more privacy and improved comfort.<ref name="defensieMfregrat">{{cite web|url=https://www.defensie.nl/onderwerpen/materieel/schepen/m-fregatten |title=Multipurposefregat (M-fregat)|publisher=defensie.nl |date=2018-05-03|language=nl|access-date=2018-06-22}}</ref>

The ''Karel Doorman'' class were designed as multi-purpose frigates that could perform a wide range of missions. Their armament reflects this by incorporating many features, such as the ability to engage [[submarine]]s, aircraft and surface vessels.<ref name="navaltechnology">{{cite web|url=https://www.naval-technology.com/projects/karel/ |title=Karel Doorman Class |publisher=www.naval-technology.com |access-date=2018-06-22}}</ref> Besides warfare the armaments can also be used to support anti-drug and piracy operations.

First amongst this class to be [[Ceremonial ship launching|launched]] was {{HNLMS|Karel Doorman|F827|6}}. [[Keel laying|Laid down]] in February 1985 and launched in April 1988, the vessel was [[Ship commissioning|commissioned]] by the Royal Netherlands Navy in May 1991. ''Karel Doorman'' was followed by {{HNLMS|Willem van der Zaan|F829|2}}, {{HNLMS|Tjerk Hiddes|F830|2}}, {{HNLMS|Van Amstel|F831|2}}, {{HNLMS|Abraham van der Hulst|F832|2}}, {{HNLMS|Van Nes|F833|2}}, {{HNLMS|Van Galen|F834|2}}, and {{HNLMS|Van Speijk|F828|2}}. Even while the ships were still under construction, Dutch authorities tried, and ultimately failed, to negotiate purchase orders by interested foreign navies.<ref>Rommelse (2008), ''Export M-fregatten, 1986-1994: De BV Nederland met vallen en opstaan'', p. 225.</ref> However, six decommissioned ''Karel Doorman''-class frigates were eventually bought by the [[Belgian Naval Component|Belgian]], [[Chilean Navy|Chilean]], and [[Portuguese Navy|Portuguese]] navies, and the proceeds were subsequently invested in development of the {{sclass|Holland|offshore patrol vessel|1}}.
