The Hawker Heron was the first fighter aircraft designed at Hawker Aircraft with a basically metal structure. 

Sydney Camm was the chief designer that introduced what became the typical structure for all Hawker aircraft until the introduction of the jet-powered Hawker P.1040.

The Air Ministry issued Specification 25/24 to Hawker for a single-seat high-speed fighter landplane and a prototype was ordered for evaluation.

The first flight of the prototype, serial number J6989, flown by P.S.W. Bulman was made in 1925.

Despite being heavier than the similar powered Woodcock, it was 15 mph (24 km/h) faster and was praised by the pilots that flew it for its excellent handling properties.

Due to little interest from the Air Ministry, only one aircraft was built and it was returned to Hawker after testing.
