British military aviation started on 10 September 1907 when the British Army Dirigible (steerable airship) No.1 'Nulli Secundus' makes its first flight at Farnborough. Other significant dates include:
The following text comes from the RAF website, with comments in square brackets.
The origins of the Royal Air Force roundel come from the First World War. The need to be able to identify aircraft soon became apparent and orders were issued at the end of August 1914 for the Union Flag to be painted on the under-surface of the lower wings. [Cochrane & Elliott (1998) show only a flag only on the rudder on 14 August at this page and also on the fuselage and wing since 26 October at this page.] This was satisfactory at low level but was confusing when the aircraft was higher as only the cross was visible. This was often mistaken for a German cross so the French system of concentric circles was adopted in October 1914. The main differences between the French and British systems was that the colours were reversed to read blue, white and red and the Union Flag was retained in miniature between the circles and the wing tips. This miniaturised Union Flag was also painted on the rudder.....The Union Flag on the rudder was replaced by red, white and blue stripes in May 1915 and in June of the same year, the Roundel, or 'Target' as it was now known, was painted on the top surface of the upper wings. The Union Flag on the aircraft was abolished altogether. [Cochrane & Elliott (1998) show an image at this page as 1915-1937. This is what later became known as RAF type A roundel - see this image.]
Aircraft of the Naval Wing of the Royal Flying Corps were marked with one red ring and the Union Flag. [Cochrane & Elliott (1998) show it in this page as Dec. 1914 - May 1915].
Since the Second World War the red disk of British aircraft markings has had a larger diameter, measuring half again the width of either of the outer rings. The reason for this change is obscure, but it may be fair to presume a mere technicality of draughtsmanship when the white was removed before the war, as a concession to camouflage and then reintroduced after the war. There were variations of the Royal Air Force roundel during the War. A fourth colour, yellow, was added to the outside of the blue circle to make the roundel more visible against the newly introduced camouflage schemes. Fighter aircraft in the early years had a yellow circle of about the same thickness of the red and white circles, whereas larger aircraft such as bombers had a much thinner yellow circle around the roundel. [Cochrane & Elliott (1998) report all these variations at this page as 1937-1942 and this page as 1942-1947. A regular roundel with a yellow border is known as type A1 in this image. The no-white roundel and fin flash is known as RAF type B in this image, and the thin white roundel is known as Type C in this image (with yellow ring it is called Type C1 - see this image). Planes could carry markings from various types at the same time. Each type has its own fin flash].
Aircraft involved operations in the Far East carried a completely different version altogether. Here, the roundel was of two colours only - a mid-blue/grey outer ring with a white centre. These were carried to avoid confusion with Japanese aircraft which carried a red circle in the centre of a thin white outer ring. [Cochrane & Elliott (1998) show two phases. The first is reported on this page with an appropriate fin flash later to be changed by replacing the inner disc to white and adding bars - see this page.]
Today, the roundel appears in three formats on RAF aircraft. Attack aircraft such as Tornados and Jaguars, Chinooks, Pumas and Merlins of the Support Helicopter Force and Hercules transports carry a two-colour roundel of dark blue outer circle with a red centre. Fighter aircraft (Tornado F3s and Eurofighters) and Nimrod maritime patrol aircraft carry a 'washed out' roundel of pale blue and red whilst the traditional blue, white and red roundel can still be found on VIP aircraft (BAe 125s and BAe146s of No 32 Squadron), Tristars and training aircraft. [Cochrane & Elliott (1998) show type A as 1947-1972, which is a mistake since
this type is used also today. They also show type B as 1972-onward and type B (low-viz) as 1985-onward. See photos of Type A at this image, Type B at this image and low-viz at this image].
