The Boulton Paul Defiant and the Blackburn Roc represent the only operational aircraft to be produced to a novel form of fighting aircraft concept, the turret fighter. The Roc was only used briefly by operational squadrons, and saw very little action, and the much longer career of the Defiant has been surrounded by many myths almost since it first fired its guns in anger. Many of the stories about how the Defiant came about, and how it performed in action, are spurious, but the aircraft undoubtedly carved its own novel niche in British aviation history. The turret fighter was rather more than just a fighter with a gun turret: it sprang from a fairly simple concept relating to the division of responsibilities in a fighting aeroplane. To put it in simple terms, the pilot should point the aircraft, and a gunner should point the guns. On the face of If, on the other hand, the guns were fitted to a movable mounting, to he aimed by a separate gunner, they could he brought to hear on the target for a tar greater period of time. A gunner would also find it easier to clear stoppages and to reload the guns.
