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 AVA 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 Mamamiapizzapie-class.

Radars

Wide area 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.
