No. 78 Squadron was reformed in November 1936 from B flight of No. 10 Squadron, originally flying Heyford night bombers. By the start of the Second World War, the squadron was flying the Armstrong Whitworth Whitley and was acting as a reserve squadron taking on pilots who had passed out from the Group Pool training units.
In the summer of 1940 the group pool training units were merged in the Operational Training Units, and No. 78 was freed to begin operations. The squadron flew its first mission on 19 July 1940.
The squadron remained part of Bomber Command's main bomber force until the end of the war. In March 1942 the Whitley was replaced by the Halifax, and the squadron retained that aircraft until the summer of 1945.
