Armament

Design edit

Armed by a crew of 90 sailors, these vessels have the reputation of being among the most difficult in bad weather. Their high windage makes them particularly sensitive to pitch and roll as soon as the sea is formed.

Their armament, consequent for a vessel of this tonnage, allows them to manage a large spectrum of missions. During the Cold War, they were primarily used to patrol the continental shelf of the Atlantic Ocean in search of Soviet Navy submarines. Due to the poor performance of the hull sonar, as soon as an echo appeared, the reinforcement of an ASM frigate was necessary to chase it using its towed variable depth sonar.[2]

Their role as patrollers now consists mainly of patrols and assistance missions, as well as participation in UN missions (blockades, flag checks) or similar marine policing tasks (fight against drugs, extraction of nationals, fisheries control, etc.). The mer-mer 38 or mer-mer 40 missiles have been landed, but they carry several machine guns and machine guns, more suited to their new missions.[citation needed]

Its construction cost was estimated at 270,000,000 French francs.[3]

As such, the building receives the cross of military value.[citation needed]

From the end of 2014, it participated in the Corymbe Mission, a naval device aimed at ensuring the permanent presence of a vessel in the Gulf of Guinea and off the coast of West Africa.[4][5]

It was on the ship that on 8 December 2017, the resumption of official diplomatic exchanges between the French ambassador in Dakar, Christophe Bigot, and the new Gambian government, following the fall of the ex-dictator Yahya Jammeh in January 2017 which led to the reopening of the French diplomatic branch in November of the same year.[4]
