Airco D.H.1

The lack of an interrupter made the pusher a natural solution for an armed fighting aeroplane. It was originally designed for a 120hp Beardmore engine, but shortages pushed the DH.1 to use a 70hp Renault instead, and the plane with the original engine was designated the Airco D.H.1A. The DH.1 was probably not shipped to France, but it was used for Home Defense and training.
