The Dokkum class was a ship class of eightteen minesweepers that were built in the Netherlands for the Royal Netherlands Navy.[4][5] They were paid for by the United States under the Mutual Defense Assistance Program (MDAP).[6][7]

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 (WU), later known as Western European Union (WEU).[3][8] Since the minesweepers of both the Dokkum and Wildervank-class are based on WU requirements, they are sometimes referred to in Dutch as WU-class minesweepers or minesweepers of the Western Union type.[9]

The ships of the Dokkum-class were made mostly from wood, only the frame and superstructure was made from aluminium.[10] It also had a double hull, with the inner hull made out of mahogany and the outer hull of teak.[10] Furthermore, they were equipped with reversible propellers.[11]

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 diesel engines and the Wildervank-class with two Werkspoor engines.[3] As a result the minesweepers of the Dokkum-class were more durable than those of the Wildervank-class.[9]

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.[3] Furthermore, the ships were equipped with two 40 mm guns.[1]

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 minehunters.[12][13] During the rebuilding the ships were equipped with a Plessey 193 minehunting system, the bridge was modified to better suit mine hunting operations, a automatic track and trace system and autopilot were installed and several other modifications were implemented.[14] The four minehunters of the Dokkum-class entered service of the Royal Netherlands Navy between 1968 and 1969.[12]

The ships were named after the smaller Dutch municipalities.[15]
