The ‘Alkmaar’-class HNLMS minehunters formed the core of the Dutch mine countermeasures fleet from the 1980s well into the 21st century. These modern minehunters were built in collaboration with Belgium and France and were designed to detect and destroy sea mines using advanced technology, rather than simply sweeping them.
