Hanriot HD.1

Hanriot · France · first flew 1916 · fighter

The Hanriot HD.1 was a World War I French single-seat fighter biplane noted for its agility and pleasant handling, though paradoxically it was adopted by Italy and Belgium rather than France, whose Aéronautique Militaire preferred the SPAD VII and XIII. It became the primary fighter of the Italian and Belgian air services.

A small, neatly proportioned biplane fighter with a rotary engine under a circular cowling, rounded wingtips, and a simple fixed undercarriage — similar to the Nieuport 17 but with a more symmetrical wing arrangement.

History

Designed by Pierre Dupont for Hanriot, the HD.1 first flew in 1916 and was rejected by France in favour of the SPAD, but Italy ordered it in large numbers and it equipped most Italian fighter squadrons through 1917–18. Belgian pilots also flew it with distinction on the Western Front.

Variants

The HD.2 was a floatplane derivative; the HD.1 itself had minor engine variants using different Nieuport or Le Rhône rotaries.

Where you'll see it
