The Naïade-class submarines, sometimes referred to as the Perle class were a group of submarines built for the French Navy at the beginning of the 20th century. There were twenty vessels in this class, which was designed by Gaston Romazotti. The class introduced internal combustion engines into French submarine design. They remained in service until just prior to the outbreak of the First World War in 1914.
