World War II Day by Day

Berlin, Germany · October 18, 1940

On this date in 1940 German aircraft maker Messerschmitt was given just 14 days to submit a pro­po­sal for a large-capa­city troop- and cargo-carrying glider. A proto­type heavy-lift glider flew Febru­ary 25, 1941, pulled by several four-engine Junkers Ju 90s. The proto­type glider’s maiden flight encour­aged Messer­schmitt to en­large the cock­pit to accom­mo­date a co-pilot and a radio oper­ator and add electric servo motors to assist the pilots in moving the huge trailing edge flaps. Out of this the Messer­schmitt Me 321 Gigant (“Giant”) emerged, not for use in Opera­tion Sea Lion, the planned inva­sion of Eng­land as originally envi­sioned, but for use in Opera­tion Barba­rossa, the Russian cam­paign, which kicked off on June 22, 1941. Standing over 33 ft tall, made of steel tubing, wooden spars, and covered in doped fabric, with clam­shell doors in the nose and massive high-mounted wings that stretched 181 ft, the air­craft could carry inside its box­car-sized belly a com­bi­na­tion of 120–130 fully equipped troops, or 60 stretcher cases with medi­cal attendants, or an 88mm gun and tractor, a medium tank, or two 4-ton trucks along with barrels of oil and gaso­line. The biggest land-based cargo aircraft of World War II, some 200 were built between June 1941 and April 1942, seeing con­sider­able ser­vice on the East­ern Front. Another 200 or so six-engine vari­ants of the Me 321, with a strengthened wing and des­ig­nated the Me 323, were built between 1942 and 1944. Four liquid-fuel rockets assisted take-off. The Me 323 “D” series had a crew of five (two pilots, two flight engi­neers, and a radio opera­tor) and was armed with five 13mm machine guns. Maxi­mum pay­load was around 20 tons with a range of 500 miles flying at 136 mph, making it slow and vul­ner­able. Losses quickly mounted. As the Allies closed in on Axis forces in their shrinking Tuni­sian redoubt, having closed the sea route between North Africa and Sicily, 27 heavily loaded Me 323s es­corted by Messer­schmitt Bf 109s flew into seven Malta-based squad­rons of Brit­ish Spit­fires and Curtiss P‑40 Warhawks. The Luft­waffe escorts downed three Allied planes but 21 of 27 Me 323s met a watery grave. The monster trans­ports, still con­sidered by the Ger­mans to be an in­valu­able asset, stayed in ser­vice, but they were increasingly regarded by Allied pilots as sitting ducks.

Messerschmitt Me 323 Gigant (“Giant”), Powered Variant of the Me 321 Military Glider

Left: A motorized variant of the Messerschmitt Me 321 heavy-lift glider, the Me 323 was largest land-based trans­port air­craft of World War II. Around 200 of these six-engine behe­moths were built before pro­duc­tion ceased in April 1944. It is believed that no Me 323s sur­vived in service beyond the sum­mer of 1944. A ruined but com­plete wreck was found in 2012 off the coast of Sardinia, Italy.
