Hawker Hector

The Hawker Hector was a British biplane army co-operation and liaison aircraft of the late 1930s, it served with the Royal Air Force and saw brief combat in the Battle of France in May 1940.


Hector Mk I

Two-seat Air Observation Post (AOP), aircraft for the RAF.

The Hector was intended as a replacement for the Hawker Audax army co-operation aircraft.

The design and the building of the prototype was done by Hawker, production aircraft were built by Westland Aircraft in Yeovil, Somerset.

Because of the demand for Rolls-Royce Kestrel engines required for the Hawker Hind program, an alternative power plant was specified.

Consequently, the 24 cylinder 805 hp (600 kW) Napier Dagger III was used.

The prototype first flew on 14 February 1936 with George Bulman as pilot.

One prototype and 178 production aircraft were built.
