The first Mustangs to see combat in World War II were RAF Mk Is. The first combat missions were recon/ground attack which soon became known as reconaissance and destroy missions. The RAF soon expanded the role of the Mk Is to include anti-shipping escort duties and low-altitude interception. The appearance of the Mustangs gave the British an aircraft at least the equal of the highly capable German Focke Wulf 190 which had proved superior to British Spitfires.
