The Tripartite class is a class of mine warfare vessel used by the navies of Belgium, France and the Netherlands, as well as Pakistan, Indonesia, Latvia, and Bulgaria.



A joint venture of the navies of France, Belgium, and the Netherlands, the Tripartite class of minehunters were conceived in the 1970s and built in the 1980s. France built the mine-hunting equipment, Belgium provided the electronics, and the Netherlands constructed the propulsion train. France and the Netherlands originally bought 15, with Belgium buying 10.

All three countries' Tripartite ships contribute at times to NATO's Standing Maritime MCM capability groups (SNMCMG1 or SNMCMG2).
