The Aircraft Torpedo Development Unit was established by the Air Ministry at Gosport, Hampshire in 1921 to undertake the development of aerial torpedoes and mines, the means of carrying and delivering them from aircraft. It worked exclusively for the Air Ministry until 1942, when control passed to the Ministry of Aircraft Production and it thereafter carried out work both for the Royal Air Force Force and the Royal Naval Air Service. The unit was passed to the Ministry of Supply control in 1946.
