Pertuisane-class destroyer (also known as the Rochefortais class)

Overview
The Pertuisane class was a small group of four destroyers built for the French Navy in the first years of the 20th century. Built at Rochefort, they were fast, lightly armed ships intended for torpedo duties and quick strikes. They served through World War I and were all scrapped after the war. The class is sometimes referred to by its Rochefort shipyard origin, and it was followed by the Arquebuse class.
