Battle of the Atlantic
Formed in July 1940 in Bordeaux-Merignac. The Geschwader was under the control of Fliegerführer Atlantik. The unit flew reconnaissance missions in the North Atlantic searching for enemy convoys and reported them of the Kriegsmarine. Later, they also attacked ships directly. On 9 February 1941, five Focke-Wulf Fw 200 of I./KG 40 in cooperation with the heavy cruiser Admiral Hipper and U-37 attacked the British convoy HG 53. The convoy lost five ships to aerial attacks. Later in the war, one or two Gruppen of KG 40 became one of several Luftwaffe bomber groups to use the Heinkel He 177A heavy bomber. In October 1944 KG 40 transferred to Germany, and was intended for conversion to the Messerschmitt Me 262 jet fighter. This never happened and the unit was disbanded on 2 February 1945.
