La Fayette Class Frigate

The French Navy’s La Fayette Class multipurpose stealth frigates were developed by DCN International (now DCNS) and built at the DCN Lorient Naval Dockyard. The French Navy awarded DCN the contracts to construct the La Fayette (F710), Surcoef (F711) and Courbet (F712) frigates in 1988, and Aconit (F713) and Guepratte (F714) in 1992.

The lead ship, La Fayette, was commissioned in 1996 and the last, Guepratte, was commissioned in November 2001. DCN have also built an anti-submarine warfare version for Taiwan (Kang Ding) and an anti-air version for Saudi Arabia (F3000S) under the Sawari II programme. All three have been launched and the first, Al Riyadh, was commissioned in July 2002.

The La Fayette Class incorporates a number of stealth features – the sides of the vessel are sloped at 10° to minimise radar cross section, surfaces have been coated in radar-absorbent paint and the profiles of external features have been reduced.

In January 2011, DCNS won a contract worth $80m to provide through-life support (TLS) services to five French frigates at Toulon naval base. The maintenance contract is for five years from 2011 to 2015.

French Navy La Fayette-class frigates to get upgrades

The French Defence Procurement Agency (DGA) has awarded DCNS a contract to renovate three of the five La Fayette-class frigates (FLF) currently in service with the French Navy.

The renovation work, which will start in 2020, will be performed in Toulon and synchronised with the scheduled overhauls of the frigates.

The first renovated FLF will be delivered in 2021.

DCNS will renew the ships’ platform and the combat systems. Work will include renovation of electronic and IT systems used to manage the vessel’s installations (propulsion, steering gear, power generation…).

The frigates’ current combat command system will be replaced by a version derived from the one used on the Charles de Gaulle aircraft carrier, the tactical data links will be modernised and the CROTALE anti-air warfare system will be replaced by 2 renovated SADRAL launchers.

Lastly, the La Fayette-class Frigates will be equipped with an anti-submarine capacity, with the integration of a hull-mounted sonar and anti-torpedo countermeasures.

“DCNS thanks the Direction Générale de l’Armement (DGA) for its confidence and welcomes this notification related to the platform and combat system modernization of the La Fayette class frigates,” Nathalie Smirnov, Head of Services at DCNS declared. “These operations are major and have never been realized so far on this kind of frigate. This modernization perfectly enhances DCNS’ role and know-how as integrator and modernizator of many systems on the French Navy’s vessels.” Source navaltoday.com

(F-710) La Fayette

The ship’s surface-to-surface missile is the Exocet MM40 from MBDA (formerly EADS Aerospatiale). Two four-cell launchers are installed in a midship position between the two masts. The anti-ship missile has a range of 70km and approaches the target in sea skimming mode at high subsonic speed, approximately 0.95 Mach. The 165kg shaped charge warhead has time delayed impact proximity fuses.

(F714) Guepratte – Image: wikimedia.org

The French Navy has awarded MBDA a contract for the Exocet MM40 Block 3 missile to be deployed on vessels from 2006. The Block 3 missile will have a new turbojet propulsion system which will give a range extended to 180km.

Exocet MM40 Block 3


The MM40 Block 3 missile, complete with a Microturbo TRI 40 turbojet engine, began development 2004 and was first tested from a ship in 2010. Improvements to the MM40 Block 3 include internal navigation and GPS upgrades. These updates, combined with a frequency modulated continuous wave radar altimeter, allows for control of the missile’s altitude over various types of terrain. This missile is armed with a 160 kg high explosive/semi-armour piercing warhead and an active radar terminal seeker 9 Additional upgrades include increased evasive capabilities such as the ability to make a 180 degree turn post-launch, allowing the MM40 to evade defense missile systems. These upgraded missiles will be both ship- and ground-launched and will be deployed first onto Forbin (Horizon)-class destroyers and then to La Fayette-class frigates.

SA 321G Super Frelon

To meet a French armed services requirement for a medium transport helicopter, Sud-Aviation flew the prototype SE.3200 Frelon (hornet) on 10 June 1959. Powered by three Turmo IIIB turboshafts, the SE.3200 had large external fuel tanks that left the interior clear for a maximum of 28 troops, and a swing-tail fuselage to simplify cargo loading. However, development was terminated in favor of a larger and more capable helicopter designed in conjunction with Sikorsky and Fiat. What was to become Western Europe’s largest production helicopter emerged with a rotor system of Sikorsky design, and with a watertight hull suitable for amphibious operation. Two military prototypes of the Super Frelon were built, the SA 3210-01 troop transport, and the SA 3210-02 maritime version for the Aeronavale on 28 May 1963.

Four pre-production aircraft were built under the new designation SA 321 Super Frelon. These were followed in October 1965 by production SA 321G anti-submarine warfare helicopters for the Aeronavale. Apart from ship-based ASW missions, the SA 321G also carried out sanitisation patrols in support of Redoutable class ballistic missile submarines. Some were modified with nose-mounted targeting radar for Exocet anti-ship missiles. Five SA 321GA freighters, originally used in support of the Pacific nuclear test centre, were transferred to assault support duties. In 2003, the surviving Aeronavale Super Frelons were assigned to transport duties including commando transport, VertRep and search and rescue.

Six radar-equipped SA 321GM helicopters were delivered to Libya in 1980-81. The SA 321G was also modified for air force and army service. Designated SA 321H, a total of 16 was delivered from 1977 to the Iraqi Air Force with radar and Exocet missiles. These aircraft were used in the Iran-Iraq conflict and the 1991 Gulf War, in which at least one example was destroyed.

Two Sagem Défense Sécurité (formerly EADS Defence & Electronics) Dagaie chaff and flare launching systems are installed on the gun deck aft of the bridge.

Dagaie chaff and flare launching systems

DAGAIE countermeasures system

The DAGAIE launcher comprises 6 or 10 munition containers, each of which is loaded with either IR or chaff rockets.
The firing sequence runs automatically and is triggered on a missile alarm from a variety of sources, such as radar, ESM systems, or optical sights, thus providing a very short reaction time. The firing direction is optimised in accordance with the threat bearing, wind-speed and direction, ship heading and speed data.
The launching of radar and IR decoys is so arranged that advanced mixed-guidance missile systems cannot discriminate between them and thus collocation of both decoys is achieved. The installation is a double mounting and comprises: (a) two trainable mountings carrying 10 replaceable containers (suitcases), each of which is loaded with either IR or I/J-band chaff projectiles.
A wide range of ammunition by Etienne Lacroix Défense provides seduction, distraction and
seduction/dissimulation modes. The electromagnetic decoys are normally based upon aluminised glass fibre chaff with rapid bloom time and they cover the I and J frequency bands. The infra-red decoys cover both the 3-5 and the 8-14 µm bands.
