The P400 patrol ships are small vessels of the French Navy. They were designed to accomplish police operations in the French Exclusive Economic Zone. They were built by the Constructions Mécaniques de Normandie, which specialise in small military craft. Two similar ships are in service in Gabon. The P400 were originally designed in two versions: one armed with Exocet MM38 missiles, and another public service version with a smaller 16-man complement; eventually neither of these versions was commissioned as the Navy chose an intermediary version.
