This section describes and illustrates the various national insignia used by the Swedish Air Force since its formation:
Upon the formation of the Swedish Air Force on July 1926, the previous Army and Navy national markings were standardised as three black crowns on a white disc. Blue and yellow rudder stripes were also introduced. The main marking was displayed in the standard six positions – above and below each wing and on each side of the fuselage.
May 1937 saw a change to a main marking that featured the national colours – three yellow crowns on a blue disc. The fin flash was removed. The main marking was displayed in the standard six positions – as before.
In 1940, with the war in Europe getting closer to Sweden, a thick yellow outline was added to the marking to enhance its visibility. This marking continues to be used today. The roundel is displayed on the fuselage sides of helicopters, and in the standard four wing positions and on the fuselage on aircraft. No fin flash is used. Transport aircraft carry SWEDISH AIR FORCE service titles.
