Hanriot H.D.1

The Hanriot HD.1 was a French World War I single seat fighter. Rejected for service with French squadrons in favor of the SPAD S.7, the type was supplied to the Belgians and the Italians with whom it proved highly successful. 831 of a total production of about 1200 were in fact produced by Italian companies under licence.

The type was also produced by the Nieuport-Macchi company of Varese, Italy, which built almost 900 HD.1s between 1917 and 1919, more than the parent firm.

The type was also supplied in small numbers to the Italians – who manufactured it in quantity and used it to replace not only Nieuports but even SPADs in their service. The type was considered (by the Italians) to be a better all-round fighter than even the SPAD S.XIII and it became the standard Italian fighter – equipping 16 of the 18 operational Italian fighter squadrons by November 1918.

SPAD S VII

The French Air Service replaced the Nieuport 17 with the SPAD S.VII. Although disadvantaged by poor forward and downward visibility from the cockpit, the SPAD S.VII was fast, durable and difficult to shoot down. It was a good performer, flown by nearly all the French aces. However it proved to be less successful in the hands of British, possibly due to the combat tactics employed by the pilots of the Royal Flying Corps. With 18 victories, Irish ace William Cochran-Patrick scored more victories with the SPAD S.VII and SPAD S.XIII than any other ace.
