caption_attribution_description: English: Folland Gnat T.Mk1 (XS102 in RAF service, now XR991/G-MOUR) during a display at Kemble Air Day on 15th June 2008 at Kemble Airport, Gloucestershire, England. Built 1964 for the RAF as XS102, put on the civil register in 1990. This aircraft, kept at Kemble, is painted in the colours of a former RAF display team who used Gnats - the Yellowjacks. The reason for the serial change is that XS102 never served with the Yellowjacks but XR991 did.
context_page_description: The Folland Gnat is a British compact swept-wing subsonic fighter aircraft that was developed and produced by Folland Aircraft. Envisioned as an affordable light fighter in contrast to the rising cost and size of typical combat aircraft, it was procured as a trainer aircraft for the Royal Air Force as well as by export customers, who used the Gnat in both combat and training capacities.
  Designed by W. E. W. Petter, the Gnat has its origins in the preceding private venture Folland Midge. The issuing of Operational Requirement OR.303 by the British Air Ministry served to motivate the type's development; the Gnat was later submitted to meet this requirement. Its design allowed for its construction and maintenance tasks to be carried out without specialised tools, making it suitable for use in countries that had not yet become highly industrialised. The Gnat has been viewed as a major motivating factor towards the issuing of the NATO NBMR-1 requirement, which sought to make available a common strike/attack light fighter with which to equip the air forces of the various NATO members.
context_section_description: The first production Gnat T.1s for the Royal Air Force were delivered in February 1962 to the Central Flying School at RAF Little Rissington. The major operator of the type was 4 Flying Training School at RAF Valley, the first aircraft being delivered in November 1962. In 1964 4 FTS formed the Yellowjacks aerobatic team with all-yellow painted Gnats. The team reformed in 1965 as part of the Central Flying School as the Red Arrows which operated the Gnat until 1979 as the RAF aerobatic demonstration team. On 14 May 1965 the last Royal Air Force Gnat T.1 to be built was delivered to the Red Arrows.
  Once pilots graduated from basic training on the BAC Jet Provost and gained their wings they were selected for one of three streams: fast jet, multi-engined, or helicopter. Those selected for fast jets were posted to RAF Valley for advanced training on the Gnat T.1, typically 70 hours of flying. Students would then move on to operational training using the Hawker Hunter, followed by a posting to an operational conversion unit for the type of aircraft to be flown.
  Following the introduction of the Hawker Siddeley Hawk into the training role as a replacement the Gnats were withdrawn from service. The largest operator 4 FTS retired its last Gnat in November 1978. Most of the retired Gnats were delivered to No. 1 School of Technical Training at RAF Halton and other training establishments to be used as ground training airframes. When the RAF had no need for the Gnats as training airframes they were sold off. Many were bought by private operators and a number are still flying today.
