The Durand de la Penne class are two guided missile destroyers operated by the Italian Navy. The design is an enlarged version of the Audace class, updated with CODOG machinery and modern sensors. Four ships were planned but the second pair were cancelled when Italy joined the Horizon project.

This class is named after a famous naval diver who served in the Regia Marina during World War II, Luigi Durand de la Penne. He, together with other members of X MAS made the most successful human torpedo mission, damaging the British battleships Queen Elizabeth and Valiant in Alexandria, December 1941, with SLCs 'Maiale'.

These new ships were meant as very advanced destroyers, with an improvement over the previous types in almost every aspect of design. Because the ships in the Italian Navy are seldom built from scratch (especially for economic reasons), it is worth considering the evolution of this project, starting with the first class of missile destroyers made in Italy. With progressive calls for better performances, this class evolved into the final design for the Durand de la Penne class destroyer.

The first step of this 'cumulative growth' was the Impavido class, the first guided missile destroyers of the navy, but still a version of the Impetuoso class. The Impavido class ships were commissioned in the early 1960s and were roughly equal to the US Navy Charles F. Adams-class destroyers. Both shared the Tartar missile system, with a Mk 13 launcher, around 40 missiles and two Fire Control radars, all this was fitted in the aft of the ship. Both also had two single 127 mm (5 in) guns, but American ships had these in single mountings and in a new model, the Mk 42, one fore and the other aft, while the Impavido made use of an older Mk 38 dual turret.
