No. 502 Squadron RAF

No. 502 (Ulster) Squadron was a Royal Auxiliary Air Force squadron that saw service in World War II. It was reformed in September 2013, and is the oldest of all the reserve squadrons, being formed in 1925.

Formation and early years
No. 502 squadron was originally formed on 15 May 1925 as No. 502 (Bomber) Squadron, a Special Reserve squadron at RAF Aldergrove, and it was composed of a mixture of regular and reserve personnel. On 1 December 1925 the name No. 502 (Ulster) Squadron was adopted. The squadron operated in the heavy night bomber role and as such it was initially equipped with Vickers Vimys from June 1925, re-equipping with Handley Page Hyderabads in July 1928. Vickers Virginias arrived in December 1931, but in October 1935 the squadron was transferred to the day bomber role for which it received Westland Wallaces, Hawker Hinds arriving in April 1937. Shortly after this, on 1 July 1937, it was transferred to the Auxiliary Air Force, the Special Reserve being disbanded.

In Coastal Command
On 28 November 1938, No. 502 (Ulster) Squadron became part of RAF Coastal Command, and was re-equipped with Avro Anson, a twin-engine, multi-role aircraft, in January 1939. When war broke out, the squadron was used to fly maritime patrols in the Atlantic Ocean off the Irish Coast. From October 1940, the Squadron flew with Armstrong Whitworth Whitley, a twin-engined medium bomber. It was reported that on 30 November 1941 the squadron became the first Coastal Command unit to make a successful attack on a U-boat with Air-to-Surface Vessel radar, sinking U-boat U-206 in the Bay of Biscay. This report has been countered with newer information that the U-206 was more probably sunk by the minefield, "Beech," laid there by the British after August 1940, and that the squadron's attack was actually on U-71, which escaped without loss.

In January 1942 the squadron officially moved to both Norfolk (RAF Docking) and Cornwall, where a maintenance station was set up at RAF St Eval. Until 1944 the squadron's main role was to carry out anti-submarine patrols. In January 1943 conversion to Handley Page Halifax GR.Mk.II, a British four-engined heavy bomber, began, with the first patrol by this type being flown on 12 March. In addition to anti-submarine patrols, now also attacks on enemy shipping off the occupied French coast were made. In September 1944 with the French coast back in Allied hands, the squadron moved to Scotland, based at RAF Stornoway, to carry out attacks on German shipping off the Norwegian coast, remaining there until the end of the war. It was disbanded on 25 May 1945.

Into the jet age
With the reactivation of the Auxiliary Air Force, No. 502 was reformed on 10 May 1946, again at RAF Aldergrove, but now as a light bomber squadron, equipped with de Havilland Mosquito B.25 from July 1946. In December night fighter de Havilland Mosquitoe replaced the bomber variant, but in June 1948 the units of the by now Royal Auxiliary Air Force all converted to the day fighter role, 502 receiving Supermarine Spitfire F.22 fighter aircraft for the purpose. Jet conversion began in January 1951 with the arrival of de Havilland Vampire FB.5, which were supplemented by the FB.9 variant in July 1954. The squadron continued to fly both types until, along with all the flying units of the RAuxAF, it was disbanded on 10 March 1957.

Reformation at Aldergrove
It was confirmed in September 2013 that No. 502 (Ulster) Squadron has reformed at Aldergrove Flying Station. As a general Squadron its mission is to provide fully trained Royal Auxiliary Air Force personnel, across a wide spectrum of roles, to support current and future worldwide commitments. No. 502 is the oldest of the reserve squadrons, having been formed in 1925, and in 2019, a new standard was awarded to the squadron as the old standard had been awarded in 1939 and was worn out.
