Floréal class frigate

From Wikipedia, the free encyclopedia

The Floréal type is a class of light "sentry frigates" designed for the needs of the French Navy after the end of the Cold War, ordered in 1989. They use construction standards of commercial ships. The ships are named after months of the Republican Calendar.

[edit] Definition of the requirements

After the end of the Cold War, it was felt that the risks of a large-scale military confrontation had all but disappeared. The Marine Nationale had to face new missions, while its escort avisos from the 80s were aging, and also badly adapted to low-risk zones.

The concept of "sentry frigate" emerged from the will of the French government to protect its Exclusive Economic Zone (12 million km²), as defined in the Montego Bay treaties. Another need was to address matters of humanitarian aid, diplomacy, or naval law enforcement. To address these missions, an onboard helicopter is clearly the optimal solution, provide versatile, swift and long-range capabilities to deliver support, ferry or rescue.

These constraints defined the need for a ship which would be small; extremely stable to allow use of a heavy helicopter in all weather; small crew, while retaining capacities to accommodate navy commandos; light armament; economic and long-range propulsion system.

[edit] Construction

To make the ship more economical, civilian construction methods were used at the Chantiers de l'Atlantique in Saint Nazaire. The ships use the SOLAS (Safety Of Life At Sea) regulations, which require the hull to have eleven watertight compartments. The rules of the classification society Det Norske Veritas are used for energy production and safety. The ships were built in series, each with six pre-fabricated parts weighing up to 570 tonnes that were assembled and welded in a dry dock. (The construction method was later used for the La Fayette class). The first trials at sea were carried out in 1991 with an entirely civilian crew, while the Marine Nationale was only present as an observer.

[edit] Equipment

The armament was ordered from the DCN Lorient, a traditional naval provider for the French Navy. The Floréal class, though designed to operate in low-risk areas, carry their own armament (they are not dependent on their helicopter).

The most visible piece of armament is the standard 100 mm multipurpose gun turret, which is a feature of most modern French warships. It is installed in one block, with the magazine shelter and the targeting computer. All Floreal frigates are fitted with two Exocet missile launchers, a Dagaie decoy launcher system, two 20 mm Mod F2 cannons, as well as a complete range of detection and counter-measure electronics.

The helicopter is a naval Panther, carrying no armament itself.
