The '''''Dokkum'' class''' was a [[ship class]] of eightteeneighteen [[minesweeper]]s that were built in the Netherlands for the [[Royal Netherlands Navy]] (RNLN).<ref name="Amstel7476">van Amstel (1991), pp. 74-7674–76.</ref><ref name="Raven184">Raven (1988), p. 184.</ref> They were paid for by the United States under the [[Mutual Defense Assistance Act|Mutual Defense Assistance Program]] (MDAP).<ref name="AH27July1955">{{cite news |author=<!--not stated--> |date=10 August 1956|title= Mijnenveger Dokkum was met ‚Wildervank' op bezoek in V.S.|url=https://resolver.kb.nl/resolve?urn=ddd:010614479:mpeg21:p004 |work= [[Leeuwarder Courant]] | language=Dutch|___location= |access-date=}}</ref><ref>{{cite news |author=<!--not stated--> |date=27 July 1955|title= Hr Ms mijnenveger Dokkum in dienst gesteld |url=https://resolver.kb.nl/resolve?urn=KBNRC01:000041292:mpeg21:a0042 |work= [[NRC (newspaper)#Algemeen Handelsblad|Algemeen Handelsblad]] | language=Dutch|___location= |access-date=}}</ref> The ships of the ''Dokkum'' class were the last dedicated minesweepers that served in the RNLN.<ref>{{cite magazine |last=Henkelman |first=K.F.J. |date=February 2010 |title=Het project Herintroductie Mijnenvegen |url=https://marineblad.nl/images/Marineblad/2010-2019/2010/Marineblad%201%20februari%202010.pdf|magazine=Marineblad |volume=120 |issue=1 |pages=22-26|language=Dutch}}</ref>
== Design ==
The minesweepers of the ''Dokkum''- class were designed by the Dutch engineer Scheltema de Heere and based on the standard requirements laid down by the [[Western Union (alliance)|Western Union]] (WU), later known as [[Western European Union]] (WEU).<ref name="Roetering108" /><ref>Schoonoord (2012), p. 36.</ref> Since the minesweepers of both the ''Dokkum'' and [[{{sclass|Wildervank-class |minesweeper|''Wildervank''-class]]4}} are based on WU requirements, they are sometimes referred to in Dutch as ''WU''-class minesweepers or minesweepers of the Western Union type.<ref name="Schoonoord58">Schoonoord (2012), p. 58.</ref>
The ships of the ''Dokkum''- class were made mostly from wood, only the frame and [[superstructure]] was made from [[aluminium]].<ref name="LC13October1954">{{cite news |author=<!--not stated--> |date=13 October 1954|title= De mijnenveger „Dokkum" niet zonder moeite te water gelaten: Nu zal het Dokkumer Diep ook uitgediept moeten worden, meent de burgemeester |url=https://resolver.kb.nl/resolve?urn=ddd:010613921:mpeg21:p007 |work= Leeuwarder Courant | language=Dutch|___location= |access-date=}}</ref> It also had a double hull, with the inner hull made out of [[mahogany]] and the outer hull of [[teak]].<ref name="LC13October1954" /> Furthermore, they were equipped with reversible propellers.<ref>{{cite news |author=<!--not stated--> |date=13 October 1954|title= Mijnenveger „Dokkum" gaat met tegenzin te water: Eerste van een klasse van 32 schepen |url=https://resolver.kb.nl/resolve?urn=MMNHA03:179255011:mpeg21:a00146 |work= Nieuwe Haarlemsche Courant | language=Dutch|___location= |access-date=}}</ref>
While the minesweepers of the ''Dokkum'' and ''Wildervank''- class are almost identical, they do differ when it comes to the engines. The ''Dokkum''- class was equipped with two [[MAN SE|MAN]] diesel engines and the ''Wildervank''- class with two [[Werkspoor]] engines.<ref name="Roetering108" /> As a result the minesweepers of the ''Dokkum''- class were more durable than those of the ''Wildervank''- class.<ref name="Schoonoord58" />
When it came to sweeping mines the ships of the ''Dokkum''- class were equipped with several different sweepers. As mechanic sweeper it had the ''Wire Mk 3 mod 2'', the magnetic sweeper consisted of the ''ML Mk 4'' and later the ''Mb 5'', and the acoustic sweepers consisted of the ''AX Mk 4v'', ''AXx Mk 6B'' and ''AX Mk 3''.<ref name="Roetering108" /> Furthermore, the ships were equipped with two 40 mm guns.<ref name="Amstel74" />
=== Conversion to minehunter ===
To keep in line with NATO requirements it was decided in 1962 to rebuild four ''Dokkum''-class minesweepers (''Dokkum'', ''Drunen'', ''Staphorst'' and ''Veere'') into [[minehunter]]s.<ref name="Woudstra154">Woudstra (1982), p. 154.</ref><ref>Schoonoord (2012), pp. 127-128127–128.</ref> During the rebuilding the ships were equipped with a ''Plessey 193'' minehunting system, the bridge was modified to better suit mine hunting operations, an automatic track and trace system and autopilot were installed and several other modifications were implemented.<ref>Roetering (1997), p. 109.</ref> The four minehunters of the ''Dokkum''- class entered service of the Royal Netherlands Navy between 1968 and 1969.<ref name="Woudstra154" />
