The French defense procurement agency (DGA) ordered on 17 November 2023 seven new offshore patrol vessels (OPV) as part of the “Patrouilleurs Hauturiers” program for the French Navy (Marine Nationale).
These “second rank” ships will have missions similar to USCG cutters. We heard about the requirement for these ships and the vessels they would replace three years ago. At that time ten ships were expected. Since then, the requirement was reduced to six and now seven. France has been building several different classes of large patrol vessels (here, here, and here).
This new class of Patrouilleurs Hauturiers (offshore patrol vessels) are expected to displace 2400 tons full load, have a range of 6,000 miles, and have accommodations for up to 84 personnel (passengers and crew). They are expected to mount the new 40mm gun.
