Tthe Douglas C-47 Skytrain lub Dakota (oznaczenie RAF) to wojskowy samolot transportowy opracowany z cywilnego samolotu Douglas DC-3. Był szeroko stosowany przez aliantów podczas II wojny światowej i pozostaje w pierwszej linii służby z różnymi operatorami wojskowymi.
Wyspecjalizowany transport oddziałów C-53 Skytrooper rozpoczął produkcję w październiku 1941 roku w fabryce Douglas Aircraft w Santa Monica w Kalifornii. Brakowało drzwi ładunkowych, mocowania podnośnika i wzmocnionej podłogi C-47. Wyprodukowano w sumie 380 samolotów, ponieważ C-47 okazał się bardziej wszechstronny.
Tthe Douglas C-47 Skytrain(known as theDakotain British service) was the military conversion of the revolutionary DC-3 airliner. General Dwight D. Eisenhower famously cited it as one of the four most vital pieces of equipment that won WWII (alongside the Jeep, the Bazooka, and the Atomic Bomb). While the German Ju 52 was a product of the late 1920s, the C-47 was a generation ahead—featuring a sleek, all-metal semi-monocoque design, retractable landing gear, and significantly more power. It was the plane that made reliable global air transport a reality.

Design Engineering: Simple, Strong, and Streamlined
The “Gooney Bird” Durability:The C-47 earned its nickname from its albatross-like endurance. Its multi-cellular wing design meant that even if a large portion of the wing was shot away, the internal structure could often still carry the load, allowing “mutilated” planes to limp home.
Military Modifications:To turn a DC-3 into a C-47, Douglas added a large double cargo door on the port side, a reinforced floor to support the weight of Jeeps or 37mm anti-tank guns, and a shortened tail cone for glider-towing shackles.
Astrodome Navigation:Unlike the civilian version, military C-47s featured a small clear bubble (astrodome) on top of the cockpit. This allowed the navigator to use a sextant to plot the plane’s position by the stars during long over-water flights.
Pratt & Whitney Reliability:The R-1830 “Twin Wasp” engines were legendary for their ability to keep running even when damaged or poorly maintained. This reliability was crucial for the treacherous “Hump” flights over the Himalayas.
Operational History: D-Day and Beyond
Operation Overlord:On the night of June 5/6, 1944, over 800 C-47s filled the skies over Normandy, dropping more than 13,000 paratroopers behind enemy lines. This remains the most iconic moment in the aircraft’s history.
“The Hump”:C-47s provided a vital lifeline to China by flying over the Himalayas from India. They braved extreme turbulence, ice, and Japanese fighters to deliver supplies that kept Chinese forces in the war.
Berlin Airlift:After the war, the C-47 (and later the C-54) saved the city of West Berlin during the Soviet blockade. C-47s landed around the clock, delivering food and coal to a starving population every few minutes.
Puff the Magic Dragon:In the Vietnam War, the C-47 was modified into the **AC-47 Spooky** gunship. Armed with three side-firing 7.62mm miniguns, it could saturate a target area with 18,000 rounds per minute, earning it a terrifying reputation among enemy ground forces.
