The Alkmaar class is a ship class of fifteen minehunters that were built in the Netherlands for the Royal Netherlands Navy.[3][4] They are based on the design of the Tripartite class, which was developed by a collaborative effort between the Netherlands, Belgium and France, and replaced the minesweepers and minehunters of the Dokkum class.[5][6][7]
Design and construction
In 1975 the Netherlands, Belgium and France signed an agreement to develop a new mine countermeasures vessel together.[8] At the same time it was also decided that each country would contribute to the construction by being responsible for certain components and systems.[6][9] As a result, the Netherlands was responsible for the main propulsion, the gearboxes and propellers.[9] France delivered the mine countermeasure and electronics systems, while Belgium build the remaining electronics and mechanic installations.[8]
The construction of the Alkmaar class started in 1979 at the shipyard of Van der Giessen-De Noord in Alblasserdam.[10] The ships were made from polyester, which required new construction methods in comparison to the previous mine countermeasure vessels that were built at the shipyard.[1][11] As a result, Van der Giessen-De Noord invested 42 million Dutch guilders to build a new dedicated production hall that had a specific climate indoors and allowed serial construction in the same way as for aircraft production.[9][11][12] Inside the production hall there was an assembly line that contained four stations, with each ship staying around 21 weeks at a station before moving to the next.[13] Besides a new hall and tools, the shipyard also had to train personnel to be able to handle fiberglass and fiberglass sheets, which were used to construct the polyester ships.[13] The construction of the 15 minehunters are estimated to have cost a total of 1.3 billion Dutch guilders.[10]
Mine countermeasure systems
To hunt mines the Alkmaar class was equipped with the French DUBM 21B sonar, which was used to detect and classify mines, a Racal Decca 1229 radar and an EVEC plotting system.[14][10] The sonar had a range of almost one kilometer and allowed the ship to search for mines up to a depth of 80 meters underwater.[15][16] In addition, each ship was equipped with two Poisson Auto-Propulsé (PAP) type 104 submarine drones that were used for mine disposal.[17][10] This PAP 104 wire guided drone had a television camera aboard for observation and could be fitted out with explosives to destroy mines from a safe distance.[17][18]
Armament
The Alkmaar class had as armament a single 20 mm machine gun.[1][2]
Service history
Between 1987 and 1989 Maassluis, Hellevoetsluis and Urk were active in the Persian Gulf as part of a Western European Union (WEU) mine clearing operation and placed under Belgian command.[19]
In 1990 Alkmaar and Zierikzee took part in the exercise Safe Pass at the west coast of America.[20]
Ships in class
The ships of the Alkmaar class are named after medium-sized Dutch municipalities that played a role in the Eighty Years' War and can also be accessed by these ships.[2][21]

In March 2023 it was reported that the Netherlands would donate two Alkmaar-class minehunters to Ukraine.[29][30] The transfer of these ships would most likely start from 2025.[31][32]
