From Wikipedia, the free encyclopedia

Hedgehog
Type Naval reconnaissance
Manufacturer Hawker Aircraft
Maiden flight 1924
Number built 1

The Hawker Hedgehog was a three seat reconnaissance biplane, to be used for naval scouting produced to meet Air Ministry Specification 37/22.

It was designed in 1923, and had its first flight the next year, piloted by FP Raynham. The crew consisted of the pilot, an observer and an air gunner. Construction was typical of the period; a wooden structure covered with fabric. The powerplant was a nine cylinder Bristol Jupiter IV radial engine driving a two-bladed wooden propeller.

On completion of the flight tests, the project was cancelled. This was due to the performance not having a sufficient increase over other aircraft. Consequently only one prototype was built. The armament of the aircraft was one fixed forward firing Vickers gun and one Lewis gun on a Scarff ring in the rear cockpit. The aircraft was fitted with floats that contained wheels to enable use as an amphibian. Also the wings could be folded, so that the width was reduced to 16 ft 7½ in (4.87 m) for storage.
