One of Britain’s newest aerial weapons, the two-seater “Defiant” built by the firm of Boulton Paul, fires four machine gurts from a hydraulically turned turret. This enables the single-engine ship to cruise alongside an enemy bomber and pour bullets into it, a feat impossible when all guns are fixed to fire straight forward. Additional arms include fourteen machine guns in the wings close to the fuselage, two cannons synchronized with the propeller and a third cannon firing through propeller shaft. Power with a 1,050-horsepower Rolls-Royce Merlin engine, the fighter has a top speed of 350 miles an hour.
