No. 10 (Army Cooperation) Squadron RCAF was formed on 5 October 1932 and renumbered as No. 110 Squadron on 15 November 1937, and then as No. 400 Squadron on 1 March 1941, as the first of the Article XV squadrons, manned and led by Canadians, but equipped with aircraft provided by the British. [2] No. 10 (Bomber) Squadron RCAF was a new, unrelated unit that was formed by the Royal Canadian Air Force on 5 September 1939 for anti-submarine warfare using the same, now disused squadron number, and was active for the duration of the Second World War. [3]
While based on the east coast of Canada and Newfoundland it established an RCAF record for 22 attacks on U-boats and successfully sank 3, garnering the unofficial nickname of North Atlantic Squadron. [4] The squadron flew the Westland Wapiti, Douglas Digby, and Consolidated Liberator.
