Boulton Paul Defiant
The Boulton Paul Defiant is a British interceptor aircraft that served with the Royal Air Force during World War II.
The Defiant was designed as a turret fighter, without any forward firing guns, also found in the Blackburn Roc of the Royal Navy.
In combat, the Defiant was found to be reasonably effective at destroying bombers but was vulnerable to the Luftwaffe’s Messerschmitt Bf 109 fighters.
The lack of forward-firing armament proved to be a great weakness in daylight combat and its potential was realized only when it was converted to night fighting.
The Defiant found use in gunnery training, target towing, electronic countermeasures and air-sea rescue. Among RAF pilots it had the nickname “Daffy”.
