The Giant of WWII- Messerschmitt Me 323 Gigant was the largest land-based transport aircraft of the war

The German military transport aircraft of World War II, Messerschmitt Me 323 Gigant (“Giant”)  was a powered variant of the Me 321 military glider and was the largest land-based transport aircraft of the war. A total of 213 are recorded as having been made, a few 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 glider-borne troops), and would later be used successfully 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 canceled, the requirement for a heavy air transport capability still existed, with the focus now on the forthcoming Operation Barbarossa, the invasion of the Soviet Union.

On 18 October 1940, Junkers and Messerschmitt were given just 14 days to submit a proposal for a large transport glider. The emphasis was still very much on the assault role: the ambitious requirement was to be able to carry either an 88 mm gun and its half-track tractor or a Panzer IV medium tank. The Junkers Ju 322  Mammut reached prototype form but was eventually scrapped due to difficulties in procuring the necessary high-grade timber for its all-wood construction and, as was discovered during the Mammut’s only test flight, an unacceptably high degree of instability inherent in the design. The proposed Messerschmitt aircraft was originally designated Me 261w — partly borrowing the designation of the long-range Messerschmitt Me 261 long-range aircraft, then changed to Me 263 (later re-used for Messerschmitt’s improved rocket fighter design) and eventually became the Me 321. Although the Me 321 saw considerable service in Russia as a transport, it was never used for its intended role as an assault glider.

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. It was decided to use 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; using French engines was thought to place no burden on Germany’s overstrained industry.

Initial tests were conducted using four Gnome engines attached to a strengthened Me 321 wing, which gave a modest speed of 210 km/h (130 mph) – 80 km/h (50 mph) slower than the Ju 52 transport aircraft. A fixed undercarriage was fitted, which comprised four small wheels in a bogie at the front of the aircraft with six larger wheels in two lines of three at each side of the fuselage, partly covered by an aerodynamic fairing. The rear wheels were fitted with pneumatic brakes, and could stop the aircraft within 200 m (660 ft).

The four-engined Me 323C was considered merely a stepping stone to the six-engined D series; it still required the five-engined Heinkel He 111Z Zwilling or the highly dangerous, “vic-style” Troika-Schlepp formation of three Messerschmitt Bf 110 heavy fighters and underwing-mounted Walter HWK 109-500 Starthilfe rocket assisted takeoff units to get airborne when fully loaded, but it could return to base under its own power when empty. This was clearly not much better than the Me 321, so the V2 prototype became the first to have six engines and flew for the first time in early 1942, becoming the prototype for the D series aircraft.




The selection of the six engines, and their specific placement on the wing’s leading edge, were fitted to reduce torque – a trio of counterclockwise rotation engines mounted on the port wing, and a trio of clockwise rotation engines on the starboard wing as seen forward from “behind” each engine, resulting in the props rotating “away” from each other at the tops of their arcs, as did the counter-rotating twin propellers on the Heinkel He 177.

By September 1942, Me 323s were being delivered for use in the Tunisian campaign and entered service in the Mediterranean theater in November 1942. The high rate of loss among Axis shipping had made necessary a huge airlift of equipment across the Mediterranean to keep Rommel’s Afrika Korps supplied.

On 22 April 1943, a formation of 27 fully loaded Me 323s was being escorted across the Sicilian Straits by Bf 109s of JG 27 when it was intercepted by seven squadrons of Spitfires and P-40s. Twenty-one of the Me 323s were lost while  three of the P-40s were shot down by the escorts.

In terms of aircraft design, the Me 323 was very resilient, and could absorb a huge amount of enemy fire, unless loaded with barrels of fuel – the Afrika Korps nicknames of Leukoplastbomber(“Elastoplast bomber”) or even more derisively as the “adhesive tape bomber”, were somewhat unfair.The Me 323 was something of a “sitting duck”, being such a slow and large aircraft. However, no transport aircraft can ever be expected to survive without something close to air superiority, and it is believed that no Me 323s survived in service beyond the summer of 1944.

A total of 198  Me 323s were built before production ceased in April 1944. There were several production versions, beginning with the D-1. Later D- and E- versions differed in the choice of the power plant and in defensive armament, with improvements in structural strength, total cargo load, and fuel capacity also being implemented. Nonetheless, the Me 323 remained significantly underpowered. There was a proposal to install six BMW 801 radials, but this never came to pass. The Me 323 was also a short-range aircraft, with a typical range (loaded) of 1,000–1,200 km (620–750 mi). Despite this, the limited numbers of Me 323s in service were an invaluable asset to the Germans and saw intensive use.








No complete aircraft survives, but the Luftwaffenmuseum der Bundeswehr (Air Force Museum of the German Federal Armed Forces) near Berlin has a Me 323 main wing spar in its collection.

A ruined but complete wreck was found in 2012, in the sea near La Maddalena, an island near Sardinia, Italy. The aircraft lies in around 200 ft (61 m) of water, around 8 nautical miles (15 km) from the coast. It was shot down by a BritishBristol Beaufighter long–range fighter on July 26, 1943, while en–route from Sardinia to Pistoia in Italy.
