Variants

The Hawker Duiker was an unusual and unsuccessful aircraft.

It was the first design at Hawker under a new chief designer, Captain Thomson, in 1922.

Much of the equipment and parts were proprietary and made by another aircraft company, Vickers, which shared the airfield at Brooklands with Hawker.

The Duiker was a parasol wing monoplane in a period where the biplane held sway.

Only one aircraft was made.
