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.

Description[edit]

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.[1]

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

Ships of the class[edit]

A total of 45 ships have been produced in the tripartite-class, below is a breakdown of how many ships each country has acquired.[2]

Belgium[edit]

Originally 10 ships were built for the Belgian navy. All remaining Belgian vessels have undergone an extensive upgrade during 2004-2008 involving replacement of the anti-mine warfare equipment. Also called "CMT" for Chasseur de Mines Tripartite, all are named after flowers and are thus sometimes called the "Flower" class in international literature.

Successor[edit]

The Netherlands and Belgium[edit]

The Netherlands and Belgium are doing a joint procurement for the replacements of the Tripartite-class/Alkmaar-class minehunters. Both countries want to procure six new mine countermeasure (MCM) vessels, which makes for a total of 12 MCM ships. The New MCM ships will include a range of unmanned systems including unmanned surface, aerial and underwater vehicles alongside towed sonars and mine identification and neutralization ROVs.[6]

Belgium gave the green-light to start the procurement on 26 January 2018 and approved a budget of 1.1 billion euros for the 6 Belgian MCM ships. The ships will replace besides the tripartite-class minehunters, also the Belgian logistical support ship BNS Godetia.[7]

Contenders[edit]

  • The Franco-Belgium consortium made up of French shipbuilders STX France and Socarenam togheter with Belgium’s EDR are bidding for the 12 new MCM vessels.[8] Their plan includes the construction of MCM vessels named Sea Naval Sollution and a multi-role frigate named Deviceseas, which will serve as mothership to the MCM vessels. All ships will have a strong focus on autonomous systems operations.[9]
