A Crusader armed with twin Oerlikon 20 mm guns for anti-aircraft use and a single .303 (7.7 mm) Vickers GO machine gun. The turret was a small polygonal turret with heavy armour, but poor situational visibility for spotting approaching aircraft. The Mk III only differed from the Mk II by the position of the radio, which was moved to the hull in order to free some space inside the turret.
