The Aigrette-class submarines were a class of two submarines built for the French Navy between 1903 and 1905. They were essentially experimental submarines, and although in service during World War I, saw no action. The class was designed by Maxime Laubeuf and used Drzewiecki drop collar launchers and external cradles to launch torpedoes.
