History of The Royal Canadian Air Force - Symbols and Insignia - Roundels

Roundels

The RCAF used British roundels and other markings until 1946, when Canada began using its own insignia identity. The British roundel existed in several versions. During the Second World War the red circle was painted out or reduced in size on some aircraft active in the Pacific theatre to avoid confusion with the Japanese Hinomaru. Roundels were also modified to be less visible on camouflaged aircraft or to make them more visible.

Canada was the first Commonwealth country to dispense with the RAF system. The maple leaf replaced the British-style inner circle to give it a distinctive Canadian character. Although the maple leaf roundel was approved for use by the RCAF in 1924, it was not until after the war that it began to be used on aircraft. It was, however, used on the ensign beginning in 1941. From 1946–1948 a roundel with a red leaf set inside a blue disk (referred to as the RCAF Type 1 roundel) was used on non-camouflaged aircraft. Several versions of the maple leaf roundel existed from wartime to 1965. Sizes of the leaf and the ring thickness sometimes changed, and some versions of the RCAF roundel included a white or yellow outline, which were specific to certain aircraft.

The realistic-looking "silver maple" style of leaf (referred to as the "RCAF" roundel) was replaced with the eleven-point stylized leaf of the new Canadian flag in February 1965 (referred to as the "CAF" roundel). A slightly-modified standardized version of this roundel (referred to as the "CAF revision E" roundel) was used by Air Command, and continues to be used by the "new" RCAF. An all-red "unification roundel" was used on a few aircraft from 1967-1968. Like the RCAF roundel, this new roundel sometimes changed - mainly in the size of the leaf and ring thickness, and one version had a white ring, which was used on certain aircraft. The current RCAF also uses a low visibility tactical grey roundel.
