Messerschmitt Me 321 & Me 323 Gigant
Although the Operation Sealion invasion of England was put on hiatus in October 1940, this was, at the the time, considered to be a temporary postponement until the forthcoming operation against Russia could be concluded. As a key piece of any future operation against England would be an airborne assault, and given Germany’s lack of specialized landing craft that could handle heavy equipment, the need was seen for a superheavy cargo glider, one that could transport a Mk.IV Panzer, a 88mm Flak piece, or 100 troops. Both Junkers and Messerschmitt were directed to design such an aircraft with all due haste, and within several weeks both firms had completed their design work. By February 1941 the Me 321 V1 prototype was ready for testing; the 321 was easily the largest aircraft of its day, and had a 10×10 foot cargo hold some 36 feet in length, loading/unloading being facilitated by a large clamshell nose.
The initial 321 flight was accomplished on 25 February 1941, with the V1 being towed aloft (with difficulty) by a Ju 90. The later Troika-Schlepp arrangement using a trio of Bf 110s proved to be both demanding and dangerous, and the He 111Z Zwilling tug was introduced.
Me 323E-2: The Gigant’s immense vulnerability to fighter attack led to efforts to improve the lumbering transport’s self defense capability. The E-2 model featured a pair of electrically-powered EDL 151 turrets in the upper surfaces of the wings.
Me 323E-2/WT: Waffentrager armored gunship version, with a nose-mounted 20mm turret, an additional pair of wing turrets, ten hand-operated machine guns. Two examples.
Me 323F: Heavyweight version with six Jumo 211R engines, and the E-2’s turrets. Prototype was the Me 323 V16.
Me 323G: Heavyweight version with six GR14R engines; Me 323 V17 prototype was never completed.
