No. 600 (City of London) Squadron RAuxAF was formed at RAF Northolt on 14 October 1925 as a unit of the Auxiliary Air Force, equipped with Avro 504 trainers and Airco DH.9A day bombers. It moved to RAF Hendon at the end of 1926, replacing its DH.9As, veterans of the First World War, with more modern Westland Wapitis in 1929. It was designated a fighter squadron in July 1934. On the outbreak of war day and night patrols were flown, experiments with airborne radar beginning in December 1939. When the Germans invaded Holland, the squadron flew patrols over the Low Countries but in view of the inadequacy of Blenheims for daylight operations, 600 Sqn was allocated to night defence only a few days later.

In World War II

In September 1940 the first Bristol Beaufighter was received, conversion being completed early in 1941. In October 1940 the squadron moved to Yorkshire and in March 1941 to south-west England, where it remained until September 1942. In November 1942, 600 Sqn moved to North Africa to provide night cover for Allied bases and shipping. It was transferred to Malta in June 1943, and in September, to Italy where it spent the rest of the war on night defence and intruder missions. Re-equipment with Mosquitoes began in January 1945 and on 21 August 1945 the squadron disbanded, having become the highest scoring night fighter squadron in the RAF.

Post-war

On 10 May 1946, 600 Sqn reformed at RAF Biggin Hill, as a day fighter squadron of the Auxiliary Air Force with Spitfires. It began to recruit during June and received its first operational aircraft in October. After receiving a De Havilland Vampire in October 1949 for jet conversion, it was allotted Meteors in March 1950 and flew these until the Royal Auxiliary Air Force disbanded on 10 March 1957.
