The Georges Leygues class (Type F70) is a class of anti-submarine frigates of the French Navy. They are polyvalent (multi-role), due to their Exocet and Crotale missile complement, making them especially suitable for defense of strategic positions, demonstrations, or highseas escorts.

The superstructures were built as to optimise resistance against nuclear explosion blasts.

The F70 is internationally labelled an "anti-submarine destroyer" (hence the "D" in the hull numbers), though the French don't use the term and refer to the ships as "frigates".

The last three ships of the class had their bridges raised one deck to overcome problems experienced by the first four in bad weather, as well as being equipped with DSBV 61 passive linear towed array sonar and several other upgraded systems.^[1]

The Cassard class AA frigates are an air defence variant of the Georges Leygues class.
