In the early days of flying in France, Armand Deperdussin and his aircraft designer, M. Bechereau, formed the Societe Pour Appareils Deperdussin, and designed and produced Deperdussin monoplanes of advanced design for the period. In 1912, the Australian Government ordered from the British Deperdussin Aeroplane Company, two single-seat trainers, Type A with 35hp Anzani Y-type three cylinder engine. These two aircraft were in the first batch of four aircraft ordered by the Commonwealth Government (the other two aircraft were BE-type biplanes). The recorded cost of the Deperdussin was 480 pounds each. The serial number CFS 5 identifies this aircraft as the 5th Australian Military aircraft.
