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 intermediate version.
Most of these craft are pre-positioned in overseas territories (DOM/TOM) where they carry out sea monitoring missions and secure the EEZ. They also execute missions in the context of French agreements with other nations, typically supporting foreign armies or carrying out humanitarian missions. Since late 2008, ships of the D'Estienne d'Orves class, with their heavy armament removed, are planned to replace the P400 in the high sea patrol role, a task for which the P400 have proved to be underweight.
The P400 are fitted with a hydraulic crane capable of lifting 2.5 tonnes. This allows to use them for anti-pollution operations, by embarking and debarking equipment and anti-pollution chemicals, and to lift out small craft whilst at sea. An unusual feature for ships of this size, the Operational Centre allows a complete monitoring of close surface situations, using radar indicators and tracking tables. The engine can now be monitored remotely, which allows for a smaller crew. The maintenance of the ship was simplified notably by choosing those solutions which allow to clean the ship whilst in populated areas. The P400 can stay 15 days at sea, and have 20 days of food supplies for 28 men.
The engines of the P400 have been a constant source of technical problems since the maiden journey of the lead ship L'Audacieuse to Dakar.
The first problem that occurred related to the carter reductor, then with the transmission, and eventually with a piston - this last item being the most worrying, since it was probably a symptom of a conception problem. This shed a bad light on Alstom who were trying to compete against German motors by MTU. French humourist Coluche came up with the witty remark Après l'Audacieuse, la Boudeuse, la Capricieuse,… voici venu le temps de la Dépanneuse ! (After the Audacieuse, the Boudeuse, the Capricieuse, time has come for the Tow-Truck!).
