The first two Messerschmitt Me 210 fighter-bombers to be destroyed over the British Isles fell to the guns of Typhoons in August 1942. During a daylight raid by the "Luftwaffe" on London on 20 January 1943, four Bf 109G-4s and one Fw 190A-4 of JG 26 were destroyed by Typhoons. As soon as the aircraft entered service, it was apparent the profile of the Typhoon resembled a Fw 190 from some angles, which caused more than one friendly fire incident involving Allied anti-aircraft units and other fighters. This led to Typhoons first being marked up with all-white noses, and later with high visibility black and white stripes under the wings, a precursor of the markings applied to all Allied aircraft on D-Day.
