France ordered five ships of the La Fayette class in 1988, the last of which entered service in 2002.

Background

In the late 1980s, the Marine Nationale started the studies for frigates adapted to low-intensity conflicts in the post–Cold War era. The ships were to serve in the large French EEZ, be adapted to humanitarian operations or low-intensity operations in support of land troops, and replace the aging A69 avisos

, which tended to prove too focused on naval operations and were ill-suited for joint operations.

Conventional warships used in low-intensity or humanitarian relief operations proved costly, with their heavy equipment and large crew. Hence came the requirement for lightly armed frigates with economical engines and small crew. In Italy, the same requirements led to the development of the Cassiopea

The Minerva class is a series of corvettes of the Italian Marina Militare.They were built in two series of four units in the 1980s and 1990s. The ships have fairly good speed and armament, including a 76mm general-purpose gun, but, due to their emphasis on anti-submarine warfare, they lack...

 type corvettes, built according to both civilian and military standards. These ships were limited to 1300 tonnes because the limited size and depth of the Mediterranean and the proximity of the homeland. The French Navy, on the other hand, had to be present in overseas territories, bases and EEZ. To be enduring enough, the ships had to reach 3000 tonnes, the size of a missile frigate. The larger displacement allows combining strong firepower (like the Minerva class) and a capacity for a medium helicopter (like the Cassiopea), along with a good autonomy and seaworthiness.

The first type of ships built on these principles were the Floréal class frigates

, built on civilian standards, with a limited armament, and carrying a medium helicopter. These ships are high endurance units designed to be operated in overseas possessions (Caribbean, Polynesia and New Caledonia) and the EEZ, where the likelihood of a naval threat is low. The speed is limited to 20 knots because of the low power engine which emphasises autonomy and reliability. To fight pirates in fast rigid-hulled inflatable boat

The niche for more hostile environments is covered by the La Fayette type, designed to operate in complex zones like the Indian Ocean

) had taught that project downsizing and reorganisations could lead to badly balanced naval capabilities. The new ships were to benefit from breakthrough on stealth ("furtivité") achieved by the DCN in the 1980s.

It took several years to materialise the concept, and the first ship was eventually launched in 1992, two years after the final design was completed. The weapon system testing took place in 1994, and particularly extensive trials were undertaken to prove the structure of the ship under a wide range of conditions. The La Fayette was eventually commissioned in March 1996.

Stealth

At the time of their commissioning, the units of the La Fayette class were the state of the art in stealth

 for warships. The shape of the hull and the superstructures is devised for the optimal reduction of the radar signature, which has been reduced by 60%: a 3000-tonne La Fayette unit has the typical radar signature of a 1200 tonne ship. Stealth is achieved with inclined flanks, as few vertical lines as possible, and very clean lines and superstructures: stairs and mooring equipment are internal, and prominent structures are covered by clear surfaces. The superstructures are built using radar-absorbent synthetic materials.

The radar cross section is equivalent to that of a large fishing boat, which can make camouflage amidst civilian ships possible; or that of a much less capable corvette, which could lead an enemy to underestimate the capabilities of the ship. In case of a direct attack, the small radar signature helps evade enemy missiles and fire control systems. The La Fayette are also equipped with jammers that can generate false radar images, as well as decoy launchers. Further point missile defence will be provided when the ships are equipped with the Aster 15

 anti-missile missiles.

Thanks to the adoption of low-power diesel motors and a special heat dissipation system, the La Fayette ships have a low thermal signature. The usual funnel is replaced with a small sets of pipes, aft of the mast, which cool the exit gas before it is released. The ships usually operate in warm areas, which further decreases the thermal contrast with the environment.

The magnetic signature is reduced by the presence of a demagnetisation

 belt.

The acoustic signature is minimized by mounting the engines on elastic supports, as to transmit as little vibrations to the hull as possible, and by rubber coating on the propellers. The La Fayette are equipped with the Prairie Masker active acoustic camouflage system, which generate small bubbles from underneath the hull to confuse sonars.

Construction

The superstructure is made of light alloy and glass-reinforced plastic, which allow a reduction in top weight. This provides adequate but sub-optimal resistance to fire. Vital zones are armoured in Kevlar

 that integrates directly into the superstructure. The ship's sides have a negative inclination of 10 degrees. The single anchor is located exactly on the stem, into which it is completely recessed. The deck where the seamanship equipment and capstans are installed is internal in order to hide it from radar.

The superstructure is built in one piece and directly integrates into the hull, with only a change in inclination. A platform is located between the main gun and the bridge. The superstructure runs continuously down to the helicopter hangar, on top of which short-range anti-air Crotale missile

The ships feature two masts. The main mast has a pyramidal structure which integrates funnels and supports the antenna of the Syracuse military communications satellite system, while the second supports the main radar.

The main gun is a stealth cupola equipped with an Oto Melara 76 mm gun replacing the 100 mm TR automatic gun. The Formidable class also uses the SYLVER launcher/Aster missile combination.

The first ship, RSS Formidable, was built by DCN, while the remaining ships were constructed by Singapore Technologies Marine.

Anti-Submarine capability includes S-70B helicopters.

, though no timetable for this has been confirmed.

The class's maximum speed is 25 knots (49 km/h) with a maximum range of 4,000 nm.

The six ships of the class are named Kang Ding (康定, FFG-1202), Si Ning (西寧, FFG-1203), Kun Ming (昆明, FFG-1205), Di Hua (迪化, FFG-1206), Wu Chang (武昌, FFG-1207), and Chen De (承德, FFG-1208) respectively, after provincial capitals in mainland China under ROC's pre-1949 political division.

Eight people involved in the contract have died in unusual and possibly suspicious circumstances.http://news.bbc.co.uk/1/hi/world/europe/3244148.stm Six ROC naval officers have been indicted on corruption charges relating to the affair.

In 2003 Taiwan's Navy sued Thomson-CSF (Thales) to recover alleged $590 million USD in kickbacks, paid to French and Taiwanese officials to grease the 1991 La Fayette deal. http://www.taipeitimes.com/News/taiwan/archives/2003/11/07/2003074910 The kickback money was deposited in Swiss banks, and under the corruption investigation, Swiss authorities froze approx. $730 million USD in over 60 accounts. In June 2007 the Swiss authority returned $34 million from frozen accounts to Taiwan, with additional funds pending. http://www.taipeitimes.com/News/front/archives/2007/06/15/2003365270
