Armstrong Whitworth Ara

Designed in 1918 around the newly developed ABC Dragonfly nine-cylinder air-cooled radial of 320hp, three prototypes of the Ara were ordered.

Delays in delivery of the Dragonfly engine led, in October 1918, to abandoning of plans to produce a Dragonfly-powered fighter in quantity. Companies with a design under development were each allocated one Dragonfly engine in December 1918 in order to enable them to complete and test one prototype.

The ABC engine proved extremely unreliable when the Ara commenced trials early in 1919. A second prototype was completed and flown before, late in 1919, Sir W G Armstrong Whitworth & Co Ltd closed its aircraft department.

The planned armament of the Ara comprised two 7.7mm Vickers guns.
