No 140 Squadron formed at RAF Biggin Hill as a home defence fighter unit. Due to the lack of German raids against London the unit was disbanded on 4 July 1918 to provide reinforcements for active squadrons.

On 17 September 1941 No 1416 Flight at RAF Benson was renumbered No 140 Squadron. It the early years of its existence it operated Spitfires for most of its reconnaissance duties but some Blenheims were used for night operations. A short-lived replacement of the Blenheims was Lockheed Ventura aircraft but these were quickly disposed of in favour of Mosquitoes. No 140 Squadron continued to operate Spitfires until 1944 when the unit converted completely onto Mosquito aircraft. Both day and night reconnaissance operations were undertaken until the end of the war. In September 1944 the squadron moved to Belgium and remained there for the rest of the war. In July 1945 it returned to the UK and on 10 November 1945 it was disbanded.
