Junkers Flugzeugwerke Ju 52/3m

Tri Piston

The Junkers Ju 52/3m is a corrugated-metal trimotor transport that became one of aviation's most iconic workhorses, first flying in 1932 and serving continuously for over eight decades. Built by Junkers Flugzeugwerke in Dessau, Germany, the "Tante Ju" (Auntie Ju) pioneered all-metal construction with its distinctive corrugated duralumin skin, which provided exceptional strength without requiring internal bracing. Originally designed as a single-engine airliner, the definitive three-engine 3m variant quickly became the standard, powered by three BMW 132 nine-cylinder radials producing 660 horsepower each. Lufthansa operated the type extensively on European routes throughout the 1930s, and the aircraft saw widespread military service as a transport and paratroop carrier during World War II, with over 4,800 built. The Ju 52's rugged construction, reliable handling, and ability to operate from unprepared strips made it invaluable in both peace and war—it could carry 17 passengers or nearly three tons of cargo, cruise at 165 mph, and maintain flight on just two engines. After the war, production continued in France and Spain into the 1950s, with CASA-built variants flying commercial routes until the 1970s. Today fewer than a dozen remain airworthy worldwide, most operated by museums and heritage foundations offering nostalgic sightseeing flights over the Alps and other scenic routes. The type's low-speed handling remains benign, with approach speeds around 75 knots and a stall in landing configuration at just 53 knots, making it forgiving for pilots transitioning from modern types.
