No. 52 Squadron of the Royal Flying Corps was formed as a Corps Reconnaissance squadron at Hounslow Heath Aerodrome on 15 May 1916. It moved to France in November that year, being the first squadron equipped with the Royal Aircraft Factory R.E.8. At first the squadron had little success with its R.E.8s, suffering many spinning accidents, and these losses affected morale so much that in January 1917 the squadron swapped its R.E.8s for the Royal Aircraft Factory B.E.2s of 34 Squadron. It re-equipped again with R.E.8s in May, flying in support of the allied offensives at Ypres that summer. In March 1918 it suffered heavy losses flying ground attack sorties against the German Spring Offensive in March 1918. The squadron became part of the Royal Air Force when the Royal Flying Corps merged with the Royal Naval Air Service on 1 April 1918, continuing in the Corps Reconnaissance role, for the rest of the war. It returned to the United Kingdom in February 1919, disbanding at Lopcombe Corner on 23 October 1919.
