The Hanriot HD.1 is a French World War I single-seat fighter aircraft. Rejected for service with French squadrons in favour of the SPAD S.VII, the type was supplied to the Aviation Militaire Belge (Belgian Military Aviation) and the Corpo Aeronautico Militare (Military Aviation Corps) of the Royal Italian Army, with both of which it proved highly successful.[1] Of a total of about 1,200 examples built, 831 were produced by Italian companies under licence.
