The FREMM, which stands for "European multi-purpose frigate", is a Franco-Italian family of multi-purpose frigates designed by Naval Group and Fincantieri. In France, this surface combatant is known as the "Aquitaine class", while in Italy it is known as the "Bergamini class". The lead ship of the class, Aquitaine, was commissioned in November 2012 by the French Navy. Italy has ordered six general purpose and four anti-submarine variants. France, on the other hand, has ordered six anti-submarine variants and two air-defense ones.
