The City class, also known as Vlissingen class, is a ship class of twelve mine countermeasure vessels (MCMV) in service with the Belgian Navy and Royal Netherlands Navy. The class is the result of a binational programme of Belgium and the Netherlands to replace their ageing Tripartite (Belgium) and Alkmaar (Netherlands) class minehunters. As part of this programme each country ordered six identical MCMVs. The new MCMVs, developed by Naval Group, will include a range of unmanned systems including unmanned surface, aerial and underwater vehicles alongside towed sonars and mine identification and neutralization remotely operated vehicles.
