The Hawker Hotspur was a Hawker Henley redesigned to take a Boulton-Paul semi-powered four gun turret.

It was designed in response to Air Ministry Specification F.9/35, which required a powered turret as the main armament to replace the Hawker Demon.

As Hawker was committed to the production of Hurricanes and Gloster to Henley production, there was insufficient capacity to introduce another type and production was abandoned.

The mock-up turret was removed and a cockpit fairing installed.

Planned production by Avro to Specification 17/36 was abandoned and the prototype, less turret, was used at the RAE Farnborough to test flap and dive brake configurations until 1942.
