The Netherlands and Belgium are doing a joint procurement for the replacements of the Tripartite-class/Alkmaar-class minehunters. Each of the two countries is procuring six new mine countermeasure (MCM) vessels, which makes for a total of 12 MCM ships. The new MCM ships, 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.
