had the red disc removed to prevent confusion with Japanese aircraft. Since the 1970s, camouflaged aircraft carry low-visibility roundels, either red and blue on dark camouflage, or washed-out pink and light blue on light colours. Most non-camouflaged training and transport aircraft retain the traditional red-white-blue roundel. The RAF's motto is "" and is usually translated from Latin as "Through Adversity to the Stars", but the RAF's official translation is "Through Struggle to the Stars". The choice of motto is attributed to a junior officer named J S Yule, in response to a request for suggestions from a commander of the Royal Flying Corps, Colonel Sykes. The badge of the Royal Air Force was first used in August 1918. In heraldic terms it is: "In front of a circle inscribed with the motto Per Ardua Ad Astra and ensigned by the Imperial Crown an eagle volant and affronte Head lowered and to the sinister". Although there have been debates among airmen over the years whether the bird was originally meant to be an albatross or an eagle, the consensus is that it was always an eagle.

The team was formed in late 1964 as an all-RAF team, replacing a number of unofficial teams that had been sponsored by RAF commands. The Red Arrows badge shows the aircraft in their trademark Diamond Nine formation, with the motto , a French word meaning "brilliance" or "excellence". Initially, they were equipped with seven Folland Gnat trainers inherited from the RAF Yellowjacks display team. This aircraft was chosen because it was less expensive to operate than front-line fighters. In their first season, they flew at sixty-five shows across Europe. In 1966, the team was increased to nine members, enabling them to develop their Diamond Nine formation. In late 1979, they switched to the BAE Hawk trainer. The Red Arrows have performed over 4,700 displays in fifty-six countries worldwide.
