Description

The Flamant class, designated Type OPV54, consists of three patrol boats operated by the French Navy. The vessels were ordered in August 1993 and constructed by Constructions Mécaniques de Normandie in Cherbourg. The class includes the Flamant (P676), Cormoran (P677), and Pluvier (P678), which were laid down and launched between 1994 and 1996. The French Navy envisages replacing these vessels with the Patrouilleurs Hauturiers class after 2027.

The vessels are designed for fishery monitoring, search and rescue, and patrolling the exclusive economic zone. Each ship is equipped with tanks for anti-pollutants and a water cannon for firefighting. Internal systems include a reverse osmosis plant for the production of fresh water. The deck layout includes an area designated for vertical replenishment. For boarding and utility missions, each boat carries a Zodiac Hurricane rigid-hulled inflatable boat powered by a water jet engine.

All three units are based at Cherbourg. Cormoran entered service in October 1997, followed by Flamant and Pluvier in December 1997. The class remains in active commission, conducting operations within the 200-nautical-mile limit of the French exclusive economic zone.
