Turret-equipped fighters became operational with the Royal Air Force during World War II as the result of the British Government's ongoing concern about German aerial attacks on the United Kingdom during World War I.

The possibility of enemy bombers, and not just German ones, once again flying over the country and dropping their deadly load on British soil had troubled them ever since. In the 1930s, a fighter fitted with a gun turret was considered to be an effective way of attacking bombers and would be a feasible alternative to conventional fighters.

The result of this concept was the Defiant, which was developed to meet this operational requirement. After a promising start during the dark days of the Battle of France, the Defiant was withdrawn from day operations, after having sustained heavy losses during the Battle of Britain.

This first volume is dedicated to the Defiant and narrates its development as a day fighter. Although ultimately the concept proved a failure, the blame does not rest solely on the Defiant itself - assumptions taken by some writers in the past - but many other factors also contributed to its failure as detailed in this volume.

Over 30 photographs, many of which previously unpublished, and profile artwork are included, as well as specification tables and pilot listings.
