Spitfire Mk IIa

''The Supermarine Spitfire was a British fighter which served with various nations from the late 1930s up into the 1950s. It was a single-engine, all-metal, low-wing monoplane with retractable landing gear. Various modifications served as fighters, interceptors, high-altitude fighters, fighter-bombers and reconnaissance aircraft. A total of some 20,300 Spitfires of all types were built during the war, including two-seater trainers.

In the summer of 1939, an early Spitfire Mk I was fitted with the new Rolls Royce Merlin XII engine, which had a higher output of 1175 HP and was fitted with a Coffman engine starter instead of the previous Merlin's electrical starter system. This, combined with the Rotol variable pitch propeller which had been used on many Spitfire Mk Is would now form the powerplant of the new Spitfire Mk II, although some production models used the De Havilland propeller. The Mk II was some 6-7 mph faster than the later Spitfire Mk I, but still slower than the original Spitfires before a series of modifications increased the aircraft's weight. As with the Mk I, the Spitfire Mk II was produced with either eight machine guns as the Spitfire Mk IIA, or two 20mm cannon and four machine guns as the Mk IIb. The earlier problems with cannon fitted to the Mk IB had now been solved by introducing a belt feed system to the weapon to replace the earlier drum, turning the cannon on its side and fitting a blister on the wing to house the new mechanism.

920 Spitfire Mk IIs entered service; 750 Mk IIA and 170 MK IIB, although fighters used in the air-sea rescue role were later designated Mk IIC. The Spitfire II quickly replaced the Spitfire I, with the older variant being relegated to use in Operational Training Units. By April 1941, RAF Fighter Command had completed re-equipping with the Mk II, although this too would soon be replaced by the Mk V.''
