Hawker Aircraft Ltd at Kingston was arguably the most successful and long-lasting manufacturer of military aircraft in Great Britain and Europe. In its various evolved manifestations – Hawker Aircraft, Hawker Siddeley Aviation, British Aerospace – its output of war winning aircraft, mainly fighters, was unsurpassed. From the Hart and Hurricane through the Hunter, Harrier and Hawk, the company consistently produced aircraft that the UK fighting services wanted. But some designs, for whatever reason, failed to reach flight or were declined by the services.

With their sometimes advanced aerodynamics and technology, these aircraft could have had successful service careers but instead were abandoned, their stories failing to reach mainstream consciousness. Having not received their just dues, the present book seeks to redress this omission. The reasons for failure are many and varied, often financial or political, but in each case the reasons behind the failure of the design are examined.

In a wide-ranging investigation that documents the origins of Hawker Aircraft Ltd and its famous Project Office, this work, the third in Christopher Budgen’s investigation of the inner workings of Hawker Aircraft, is a fitting tribute to the many who made the company the success it was.
