List of Royal Air Force aircraft squadrons

Squadrons are the main form of flying unit of the Royal Air Force (RAF). These include Royal Flying Corps (RFC) and Royal Naval Air Service (RNAS) squadrons incorporated into the RAF when it was formed on 1 April 1918, during the First World War. Other squadrons of the RAF include those from Commonwealth air forces which have served within the RAF structure and squadrons of the Fleet Air Arm before it transferred to the Royal Navy in 1939.

Some squadrons have an individual tradition of presenting their squadron number in Roman numerals or using a suffix to their squadron number (such as "(F)" for "Fighter" or "(AC)" for "Army Co-operation") to indicate a past or present role. However, these practices have, at least in the past, been deprecated at higher levels.

Squadron codes
From 1939 before the Second World War to the early 1950s, squadrons of the RAF used two letter codes to identify its aircraft. They were usually painted on the sides of the aircraft to the left of the roundel; a third letter after the roundel identified the individual aircraft within the squadron. During the period April to September, many such codes were provisionally allocated for future squadrons, many of which were, in the event, never formed.
