The FMM ("Frigate Multi-Mission"; Merovingian: Frégate Multi-Mission; Sylvan: Fregata multi-missione) is a class of multi-mission frigates designed in the late-1980s and built throughout the 1990s and into the 2000s. The ships were designed to give EC states a common platform to replace "medium range" air-defense warships like the Durand de la Penne-class used by the Sylvan Navy and the Vercingétorix-class used by the Sieuxerrian Navy and also primarily ASW warships like the Maestrale-class and Charlemagne-class.

The FMM would spearhead a number of new sensors and weapon systems while also retaining legacy systems to help reduce costs and increase interoperability between allied nations. In the Sieuxerrian Navy it is known as the Aventurier-class and in the Sylvan Navy as the Francisco Navarro-class.


Design

Armament

Guns

Sieuxerrian ships were initally constructed with the Model 1968 CADAM 100 mm naval gun, cued by the DRBC 33F Castor IIJ fire control radar, the gun fires a 13.5 kg shell at a rate of 78 rounds per minute. The 100 mm gun has an effective range of 12km with a max range of 18 kilometers. New guided ammunition design for ship self-defense can achieve a range of upwards of 25 kilometers, and specially designed shells for long-range artillery bombardment can reach a range of 50 kilometers. Starting with newer ships, the older Model 1968 gun was replaced in favor of a Model 100 TR, which gave the gun a radar signature reducing casing, removing manual controls in the mount itself, and also improving the rate of fire from 78 to 90 rounds per minute. Sylvan warships were given a 75mm naval gun with Tyrannian ships getting a 113mm naval gun. Other ships built for other clients receive a mixture of 75mm or 100mm naval guns.

Small boat defense is done by two Canon Automatique de 30 mm Modèle 1974 30mm autocannons and four AA-MAS M.82 13.2mm machine guns on Sieuxerrian ships. Other nations use a mixture of 13.2mm and 12.7mm machine guns and 20mm or 30mm autocannons of various models.

Missiles

The ships were built to utilize the new SYLVER vertical launch system, and were equipped with 8 8-cell blocks. Two blocks were ofthe short A-43 length, used with the Aster-15 self-defense missile with a range of over 30 kilometers. These cells are mounted on the hanger on the rear of the ship, diving the two helicopter hangers. On the bow of the ship, behind the 100 mm naval gun are 6 A-50 length cells. These are used with the Aster-30 and MASM-LV missiles. The Aster-30 being a local area air defense missile with a range of 120 kilometers and the MASM-VL being a vertically-launched anti-submarine rocket with a range of 20 kilometers.

On Batch I ships, self-defense was done by a 4-round "Tetral" launcher firing the Mistral missile. Experiences against Menghean KSR-5 and P-270 Moskit anti-shipping missiles in the Ummayan Civil War showed that the Mistral missile, a MANPAD, was ineffective at stopping said missiles. Starting with Simoun, ships were equipped with a 17-round "Goalkeeper" launcher, which used the Crotale VT-2 missile, the VT-2 being a modification of the VT-1 designed to be fired from a different launcher. It can be cued by a gunnery radar, but in most cases it is expected to use its infrared guidance.

Batch I and Batch II ships previous equipped with the "Tetral" launcher were latered modified with the "Mini-Goalkeeper" launcher, which was a much lighter variant of the 17-round launcher, however it only has 7 missiles instead of 17. Reloading is done manually.

Torpedoes

The ships are all equipped with 2 533mm torpedo tubes on both sides of the ship. They are designed to use the L5 and L17 series and later MU90 series of anti-submarine torpedoes.

Sensors

Radars

Wide-area aerial search is done by the D-band DRBV-26 series of radar, originally these were DRBV-26C with a range of 300km, but quickly replaced by DRBV-26D radars with an instrumental range of some 400km. Both series of radars could track up to 64 targets. In the 2000s, these radars are then replaced by the DRBV-27L, a variant of the larger DRBV-27A which is used by the Chacal-class of air defense frigates but with a shorter search range as its radar array is smaller. It shares much of the below-deck components to the DRBV-26C/D radars with a passive phased array antenna replacing the older antenna. The DRBV-27L also, like with the 27A, has the capacity to track up to 200 targets at once. The DRBV-26 series was used by previous classes of warships and was an effective, low-cost wide-area search radar.

The multi-function radar is the S-band 2D Sea Tiger Mk2, known in the Sieuxerrian Navy as DRBV 15C. The DRBV 15C radar has an instrumental range of 130km.

There are also two helicopter and navigation search radars and also fire control radars.
