The Cassard class (Type F70 AA) was a class of two anti-air warfare destroyers of the French Navy introduced in the latter 1980s/early 1990s. The class was an air defence variant of the Georges Leygues class. The two classes have a different armament and propulsion system mounted on an identical hull.^[1] Their primary role was to provide air cover for a fleet, an aeronaval group, a convoy & a littoral point. Their secondary role was to manage air assets coordination & aircraft control for the force, especially through Link 16.They can also be used for research, identification or presence missions. Both ships were assigned to the Force d'Action Navale.^[2] The lead ship of the class, Cassard, was retired in 2019 followed by the retirement of Jean Bart in 2021.

The experience gained during the design and construction of the Cassard type was used for the design of the La Fayette class.
