The Nordenfelt-class Ottoman submarine Abdül Hamid (1886) was the first submarine in history to fire a torpedo whilst submerged. Two submarines of this class, Nordenfelt II (Abdülhamid, 1886) and Nordenfelt III (Abdülmecid, 1887) joined the Ottoman fleet. They were built in pieces by Des Vignes (Chertsey) and Vickers (Sheffield) in England, and assembled at the Taşkızak Naval Shipyard in Istanbul, Turkey.
