The Messerschmitt Me 323 Gigant ("Giant") was a German military transport aircraft of World War II. It was a powered variant of the Me 321 military glider and was the largest land-based transport aircraft to fly during the war. In total, 213 were made, with 15 being converted from the Me 321. The Me 323 was the result of a 1940 German requirement for a large assault glider in preparation for Operation Sea Lion, the projected invasion of Great Britain. The DFS 230 light glider had already proven its worth in the Battle of Fort Eben-Emael in Belgium (the first ever assault by gliderborne troops), and would later be used in the invasion of Crete in 1941. However, in order to mount an invasion across the English Channel, the Germans would need to be able to airlift vehicles and other heavy equipment as part of an initial assault wave. Although Operation Sea Lion was cancelled, the requirement for a heavy air transport capability remained, with the focus shifting to the forthcoming Operation Barbarossa, the invasion of the Soviet Union. Early in 1941, as a result of feedback from Transport Command pilots in Russia, the decision was taken to produce a motorized variant of the Me 321, to be designated Me 323. French Gnome et Rhône GR14N radial engines, rated at 1,180 PS (1,164 hp, 868 kW) for take-off as used in the Bloch MB.175 aircraft were chosen for use. This would reduce the burden on Germany's strained industry. Like the Me 321, the Me 323 had massive, semicantilever, high-mounted wings, which were braced from the fuselage out to the middle of the wing. To reduce weight and save aluminium, much of the wing was made of plywood and fabric, while the fuselage was of metal-tube construction with wooden spars and covered with doped fabric, with heavy bracing in the floor to support the payload. The "D" series had a crew of five - two pilots, two flight engineers, and a radio operator. Two gunners could also be carried. The flight engineers occupied two small cabins, one in each wing between the inboard and centre engines. The engineers were intended to monitor engine synchronisation and allow the pilot to fly without worrying about engine status, although the pilot could override the engineers' decisions on engine and propeller control.
