The L3s were short-ranged (RO) submarines completed between 1922 and 1923 at the Mitsubishi shipyard in Kobe. They were based on the British L class. They were of limited usefulness, particularly since they could only fire obsolete 18" torpedoes, and they had already been relegated largely to training duty by the start of the war. All were decommissioned in May 1945.
