The Messerschmitt Me 323 Gigant (meaning "Giant") was a German heavy military transport aircraft utilized during World War II. It evolved as a powered version of the Me 321 military glider and held the distinction of being the largest land-based transport plane operational in the conflict. A total of 213 units were produced, including fifteen conversions from the Me 321.
Development
The origin of the Me 323 traces back to a German demand in 1940 for a substantial assault glider intended for Operation Sea Lion, the planned invasion of Britain. The smaller DFS 230 glider had demonstrated effectiveness during the Battle of Fort Eben-Emael in Belgium—the first-ever gliderborne troop assault—and was later employed during the invasion of Crete in 1941.
Nevertheless, an amphibious assault across the English Channel necessitated airlifting heavy machinery and vehicles within the initial landing forces. Although Operation Sea Lion was ultimately abandoned, the need for a large-capacity air transport persisted, shifting focus toward Operation Barbarossa, the forthcoming invasion of the Soviet Union.
On October 18, 1940, both Junkers and Messerschmitt were tasked with delivering proposals for a large transport glider within a two-week deadline. The requirement emphasized assault capabilities, aiming to carry either an 88 mm gun with its half-track tractor or a Panzer IV medium tank. While Junkers developed the Ju 322 Mammut prototype, it was ultimately abandoned due to difficulties sourcing quality timber for its all-wood design and inherent instability revealed during its maiden flight. The Messerschmitt design initially bore the designation Me 261w, borrowing from the long-range Messerschmitt Me 261, then was renamed Me 263 (a designation later reassigned to an advanced rocket fighter), before finally becoming the Me 321. Although widely used on the Eastern Front as a transport, it never fulfilled its original function as an assault glider.
Me 323
In early 1941, prompted by feedback from Transport Command pilots operating in Russia, it was decided to develop a powered variant of the Me 321, named Me 323. To alleviate pressure on Germany’s industrial resources, French-made Gnome et Rhône GR14N radial engines producing approximately 1,180 PS (1,164 hp, or 868 kW) at takeoff—previously used on the Bloch MB.175—were selected.
Initial trials involved mounting four Gnome engines on reinforced Me 321 wings, achieving a modest top speed of about 210 km/h (130 mph), which was roughly 80 km/h (50 mph) slower than the standard Ju 52 transport. The aircraft featured fixed landing gear comprising four small wheels arranged in a bogie at the front and six larger wheels in two groups of three along each side of the fuselage; these wheels were partially enclosed by aerodynamic fairings. Pneumatic brakes on the rear wheels enabled stopping within approximately 200 m (660 ft).
The four-engine Me 323C served as an intermediary toward the six-engine D series. Fully loaded, it still required either a five-engine Heinkel He 111Z Zwilling tug or a hazardous Troika-Schlepp formation composed of three Messerschmitt Bf 110 fighters equipped with underwing-mounted rocket-assisted takeoff units to become airborne. However, when empty, it could fly back independently—a slight improvement over the Me 321. The V2 prototype introduced six engines and made its first flight in early 1942, establishing the foundation for subsequent D-series models.
To counteract torque effects from multiple engines, three counterclockwise rotating engines were installed on the port wing and three clockwise rotating engines on starboard—when viewed from behind each engine—resulting in propellers spinning outward at their top arcs.
Design
Similar to its predecessor Me 321, the Me 323 featured expansive semi-cantilever high wings supported by bracing extending from fuselage to mid-wing. To minimize weight and conserve scarce aluminium supplies, much of the wing structure utilized plywood and fabric materials. The fuselage consisted of metal tubing with wooden spars covered by doped fabric; reinforced floor bracing provided strength for heavy cargo loads.
The "D" series accommodated a crew complement of five: two pilots, two flight engineers, and one radio operator. Additionally, two gunners could be carried. Flight engineers were stationed in small cabins located within each wing between inner and central engines. Their role was to oversee engine synchronization and allow pilots to focus solely on flying; however, pilots retained authority to override engine control decisions made by engineers.
Maximum payload capacity reached roughly twelve tonnes; at this weight threshold rocket-assisted takeoff units (Walter HWK 109-500 Starthilfe) originally developed for the Me 321 were required to facilitate liftoff. These rockets were mounted beneath wings beyond engine positions with fittings allowing installation of up to four units. Cargo bay dimensions measured approximately 11 m (36 ft) in length, 3 m (10 ft) in width, and 3.4 m (11 ft) in height. Typical cargo included one 15 cm sFH 18 heavy howitzer (5.5 tons) plus its associated Sd.Kfz. 7 half-track artillery tractor (11 tons), two trucks weighing about 3.6 tonnes ([convert: unknown unit]) each, large quantities such as up to 8,700 loaves of bread, an 88 mm Flak gun with accessories, fuel drums (52 drums totaling roughly 252 litres (55 imp gal; 67 US gal)), personnel loads up to approximately130 soldiers or alternatively up to60 stretchers.
While some existing Me 321 gliders were converted into powered Me 323 variants, most units were manufactured as six-engine transports from inception. Early models employed wooden two-blade propellers whereas later versions adopted metal three-blade variable-pitch propellers.
With a maximum speed around 219 km/h (136 mph) at sea level, armament consisted of six machine guns firing from dorsal positions aft of wings and along fuselage sides—typically MG 131s in caliber13 mm (.51 inch)—operated by gunners alongside radio operators and flight engineers.
Operational history
By September 1942, deliveries of Me 323 transports commenced for deployment during the Tunisian campaign. They entered active service across Mediterranean theaters starting November 1942 as Axis shipping losses escalated sharply. Airlifting supplies became essential to sustain Rommel’s Afrika Korps.
On April 22, 1943, a formation comprising twenty-seven fully loaded Me 323s escorted by Messerschmitt Bf 109 fighters from Jagdgeschwader 27 crossed over Sicilian Straits when intercepted by seven squadrons consisting of Supermarine Spitfires (No. 1 Squadron SAAF) and Curtiss P-40 Kittyhawks (No. 7 South African Wing). Of these transports, sixteen or seventeen were shot down while escorts reportedly downed three or four P-40s.
Overall production totaled198 aircraft before manufacturing ended in April 1944. Multiple production variants existed beginning with D-1 series followed by D- and E-series models differing primarily in engine configurations and defensive armaments alongside structural reinforcements that enhanced payload capacity and fuel reserves. Despite these upgrades, powerplant limitations persisted—the proposed installation of six BMW 801 radial engines never materialized. Range remained relatively limited between1,000 and1,200 km (620–750 miles) when fully loaded. Nonetheless, due to scarcity of alternatives in heavy airlift capability within Luftwaffe inventory, these aircraft played vital roles throughout their operational tenure.

Surviving aircraft
No intact examples have survived into present day. However, one main wing spar component is preserved at Berlin’s Luftwaffenmuseum der Bundeswehr (German Air Force Museum). In addition, a largely intact wreckage was discovered submerged off La Maddalena island near Sardinia in Italy during2012 resting at approximately60 meters depth about eight nautical miles offshore. This particular aircraft had been shot down on July26,1943 while en route from Sardinia toward Pistoia in Italy by a British Bristol Beaufighter long-range fighter.
