The Impetuoso class were the first post-World War II destroyers built for the Italian Navy. The hull design was based on the uncompleted Comandante-class destroyers but American equipment (guns, radar, machinery) was used. A scheme to install guided missiles during a modernisation programme was proposed but not carried out. The two ships were ordered in 1952, entered service in 1957 and were retired in the early 1980s.
