MI15, the British Military Intelligence Section 15 (now defunct), was a department of the British Directorate of Military Intelligence, part of the War Office. It was set up in 1942 to handle aerial photography (compare with MI4). In 1943 this function was transferred to the air ministry and MI15 became responsible for the coordination of intelligence about enemy anti-aircraft facilities.
