Boulton Paul P.82 Defiant

Two-seat fighter with the four-gun armament concentrated in a powered turret. The Defiant was a fine aircraft, but the tactical concept was bad and the weight of the gun turret detoriated performance. After the initial succes heavy losses followed; it was then used as a night fighter for some time and later as a target tug.
