be equipped with jet-powered aircraft, and the highest score of any British night fighter squadron. In the Battle of Britain, the AAF provided 14 of the 62 Squadrons in RAF Fighter Command's Order of Battle and accounted for approximately 30% of the accredited enemy kills. Indeed, in 11 Group Fighter Command, that saw the heaviest fighting over South East England in 1940, of the 15 top scoring squadrons, eight were auxiliary. The losses sustained during the Battle of Britain, as with all other squadrons, were replaced by drafting in regular and RAFVR pilots. In fact, the volunteer reserves of the RAF outnumbered the regular RAF pilots in the Battle of Britain. The Tactical Air Force squadrons were chosen to carry out several successful ultra low-level raids on key 'pin-point' targets in occupied Europe. The Balloon Squadrons also played their part, downing and deterring many hostile aircraft, and were accredited with the destruction of 279 V-1 flying bombs. The Auxiliary Air Force was also responsible for the anti-aircraft balloon defences of the UK. At the outbreak of war in 1939 there were about 42 Squadrons operating barrage balloons, with the number of squadrons peaking at about 102 in 1944. Cold War These achievements were honoured by the prefix "Royal", conferred by King George VI in 1947. Twenty of the pre-war squadrons were reformed postwar as fighter units. Events after the Second World War heralded a time of great danger for the UK: the onset of the Cold War with the Communist Bloc leading to the Berlin Air Lift and ultimately the outbreak of the Korean War in June 1950. During these crises the RAuxAF fighter squadrons, the five newly formed Air Observation Post (AOP) squadrons and other RAuxAF units, played their part in the UK's air defence and participated in many NATO air exercises. In 1951, at the height of the Korean War, all 20 RAuxAF fighter squadrons (representing one third of Fighter Command strength) were called up for three months full-time service; they were required for home defence in place of regular squadrons earmarked for deployment to Korea. In the event RAF fighter squadrons were not needed in Korea, but the RAuxAF squadrons were retained for intensive refresher training at their home bases. On 10 March 1957 all 20 RAuxAF fighter squadrons were disbanded, along with the five post-war AOP squadrons and the Light Anti-Aircraft ground-based squadrons of the Royal
