The Douglas DC-3 is a propeller-driven airliner manufactured by the Douglas Aircraft Company, which had a lasting effect on the airline industry in the 1930s to 1940s and World War II.

It was developed as a larger, improved 14-bed sleeper version of the Douglas DC-2.

It is a low-wing metal monoplane with conventional landing gear, powered by two radial piston engines of {{cvt|1,000|-|1,200|hp}}. Although the DC-3s originally built for civil service had the Wright R-1820 Cyclone, later civilian DC-3s used the Pratt & Whitney R-1830 Twin Wasp engine.{{cite web |title=Douglas DC-3 and C-47 Engines |url=http://www.dc-3.co.za/dc-3-c-47-engines.html |website=The Dakota Association of South Africa |access-date=April 10, 2023}}

The DC-3 has a cruising speed of {{cvt|207|mph}}, a capacity of 21 to 32 passengers or 6,000 lbs (2,700 kg) of cargo, and a range of {{cvt|1500|mi}}, and can operate from short runways.

The DC-3 had many exceptional qualities compared to previous aircraft. It was fast, had a good range, was more reliable, and carried passengers in greater comfort. Before World War II, it pioneered many air travel routes. It was able to cross the continental United States from New York to Los Angeles in 18 hours, with only three stops.

It is one of the first airliners that could profitably carry only passengers without relying on mail subsidies.{{cite magazine |author=Kathleen Burke |date=April 2013 |url=http://www.smithsonianmag.com/history/how-the-dc-3-revolutionized-air-travel-5444300/?no-ist |title=How the DC-3 Revolutionized Air Travel|magazine=Smithsonian}}{{Cite web|title=Boeing: Historical Snapshot: DC-3 Commercial Transport|url=https://www.boeing.com/history/products/dc-3.page|access-date=2020-12-10|website=www.boeing.com|url-status=dead|archive-url=https://web.archive.org/web/20230604085953/https://www.boeing.com/history/products/dc-3.page|archive-date=June 4, 2023}} In 1939, at the peak of its dominance in the airliner market, around ninety percent of airline flights on the planet were by a DC-3 or some variant.{{Cite web |title=Douglas DC-3 {{!}} National Air and Space Museum |url=https://airandspace.si.edu/collection-objects/douglas-dc-3/nasm_A19530075000 |access-date=2024-04-21 |website=airandspace.si.edu |language=en}}

Following the war, the airliner market was flooded with surplus transport aircraft, and the DC-3 was no longer competitive because it was smaller and slower than aircraft built during the war. It was made obsolete on main routes by more advanced types such as the Douglas DC-4 and Convair 240, but the design proved adaptable and was still useful on less commercially demanding routes.

Civilian DC-3 production ended in 1943 at 607 aircraft. Military versions, including the C-47 Skytrain (the Dakota in British RAF service), and Soviet- and Japanese-built versions, brought total production to over 16,000.

Many continued to be used in a variety of niche roles; 2,000 DC-3s and military derivatives were estimated to be still flying in 2013;{{cite web|url=http://www.bbc.com/culture/story/20131009-dc3-still-flying-at-70|title=The Douglas DC-3: Still revolutionary in its 70s|author=Jonathan Glancey |author-link=Jonathan Glancey |publisher=BBC |date=2013-10-09}} by 2017 more than 300 were still flying.{{cite web |url=https://www.popularmechanics.com/military/aviation/a27640/dc-3-badass-plane/#:~:text=More%20than%2016%2C000%20DC%2D3s,the%20DC%2D3%20came%20along. |url-access=subscription |archive-url=https://web.archive.org/web/20200502150628/https://www.popularmechanics.com/military/aviation/a27640/dc-3-badass-plane//#:~:text=More%20than%2016%2C000%20DC%2D3s,the%20DC%2D3%20came%20along. |archive-date=2020-05-02 |title=Why the DC-3 is such a Badass Plane |publisher=Eric Tegler, Popular Mechanics, August 8, 2017|access-date=August 22, 2020}} As of 2023, it is estimated about 150 are still flying.{{Cite web |date=2023-12-18 |title=The plane that won't quit: celebrating the Douglas DC-3. |url=https://www.gardenofmemory.net/the-plane-that-wont-quit-celebrating-the-douglas-dc-3/ |access-date=2023-12-24 |website=The Garden of Memory |language=en}}

Design and development

"DC" stands for Douglas Commercial. The DC-3 was the culmination of a development effort that began after an inquiry from Transcontinental and Western Airlines (TWA) to Donald Douglas. TWA's rival in transcontinental air service, United Airlines, was starting service with the Boeing 247, and Boeing refused to sell any 247s to other airlines until United's order for 60 aircraft had been filled.O'Leary 1992, p. 7. TWA asked Douglas to design and build an aircraft that would allow TWA to compete with United. Douglas' design, the 1933 DC-1, was promising, and led to the DC-2 in 1934. The DC-2 was a success, but with room for improvement.

The DC-3 resulted from a marathon telephone call from American Airlines CEO C. R. Smith to Donald Douglas, when Smith persuaded a reluctant Douglas to design a sleeper aircraft based on the DC-2 to replace American's Curtiss Condor II biplanes. The DC-2's cabin was {{convert|66|in|m}} wide, too narrow for side-by-side berths. Douglas agreed to go ahead with development only after Smith informed him of American's intention to purchase 20 aircraft. The new aircraft was engineered by a team led by chief engineer Arthur E. Raymond over the next two years, and the prototype DST (Douglas Sleeper Transport) first flew on December 17, 1935 (the 32nd anniversary of the Wright Brothers' flight at Kitty Hawk) with Douglas chief test pilot Carl Cover at the controls. Its cabin was {{cvt|92|in}} wide, and a version with 21 seats instead of the 14–16 sleeping berthsBerths were {{cvt|77|in|m}} long; lowers were {{cvt|36|in}} wide and uppers were {{cvt|30|in}}. of the DST was given the designation DC-3. No prototype was built, and the first DC-3 built followed seven DSTs off the production line for delivery to American Airlines.Pearcy 1987, p. 17.File:dc3.takeoff.thales.arp.jpg C-47B at RAF Hullavington in 2005]]

The DC-3 and DST popularized air travel in the United States. Eastbound transcontinental flights could cross the U.S. in about 15 hours with three refueling stops, while westbound trips against the wind took {{Frac|17|1|2}} hours. A few years earlier, such a trip entailed short hops in slower and shorter-range aircraft during the day, coupled with train travel overnight.O'Leary 2006, p. 54.

Several radial engines were offered for the DC-3. Early-production civilian aircraft used either the 9-cylinder Wright R-1820 Cyclone 9 or the 14-cylinder Pratt & Whitney R-1830 Twin Wasp, but the Twin Wasp was chosen for most military versions and was also used by most DC-3s converted from military service. Five DC-3S Super DC-3s with Pratt & Whitney R-2000 Twin Wasps were built in the late 1940s, three of which entered airline service.

=Production=

Total production including all military variants was 16,079.Gradidge 2006, p. 20. More than 400 remained in commercial service in 1998. Production was:

Production of DSTs ended in mid-1941 and civilian DC-3 production ended in early 1943, although dozens of the DSTs and DC-3s ordered by airlines that were produced between 1941 and 1943 were pressed into the US military service while still on the production line.Pearcy 1987, p. 76Pearcy 1987, pp. 69–117 Military versions were produced until the end of the war in 1945. A larger, more powerful Super DC-3 was launched in 1949 to positive reviews. The civilian market was flooded with second-hand C-47s, many of which were converted to passenger and cargo versions. Only five Super DC-3s were built, and three of them were delivered for commercial use. The prototype Super DC-3 served the US Navy with the designation YC-129 alongside 100 R4Ds that had been upgraded to the Super DC-3 specifications.

Early U.S. airlines like American, United, TWA, Eastern, and Delta ordered over 400 DC-3s. These fleets paved the way for the modern American air travel industry, which eventually replaced trains as the most common means of long-distance travel across the United States.

In 1936, KLM Royal Dutch Airlines received its first DC-3, which replaced the DC-2 in service from Amsterdam via Batavia (now Jakarta) to Sydney, by far the world's longest scheduled route at the time. In total, KLM bought 23 DC-3s before the war broke out in Europe.{{citation needed|date=August 2015}} In 1941, a China National Aviation Corporation (CNAC) DC-3 pressed into wartime transportation service was bombed on the ground at Suifu Airfield in China, destroying the outer right wing. The only spare available was that of a smaller Douglas DC-2 in CNAC's workshops. The DC-2's right wing was removed, flown to Suifu under the belly of another CNAC DC-3, and bolted up to the damaged aircraft. After a single test flight, in which it was discovered that it pulled to the right due to the difference in wing sizes, the so-called DC-2½ was flown to safety.[http://www.cnac.org/aircraft02.htm "CNAC'S DC-2 1/2"] Retrieved November 8, 2016.

During World War II, many civilian DC-3s were requisitioned for the war effort and more than 10,000 U.S. military versions of the DC-3 were built, under the designations C-47, C-53, R4D, and Dakota. Peak production was reached in 1944, with 4,853 being delivered.Gradidge 2006, p. 15. The armed forces of many countries used the DC-3 and its military variants for the transport of troops, cargo, and wounded. Licensed copies of the DC-3 were built in Japan as the Showa L2D (487 aircraft); and in the Soviet Union as the Lisunov Li-2 (4,937 aircraft).

After the war, thousands of cheap ex-military DC-3s became available for civilian use.{{cite book |last1=Norton |first1=Bill |title=Air War on the Edge: A History of the Israeli Air Force and Its Aircraft Since 1947 |date=2004 |publisher=Midland |isbn=9781857800883 |page=99 |url=https://books.google.com/books?id=q84hAQAAIAAJ|language=en}} Cubana de Aviación became the first Latin American airline to offer a scheduled service to Miami when it started its first scheduled international service from Havana in 1945 with a DC-3.

Douglas developed an improved version, the Super DC-3, with more power, greater cargo capacity, and an improved wing, but with surplus aircraft available for cheap, they failed to sell well in the civilian aviation market.{{cite web |title=Douglas DC-3 Dakota |url=https://www.ukhat.org/aircraft-detail?aircraft=douglas-dc-3-dakota&id=12 |website=UK Heritage Aviation Trust |access-date=November 9, 2019 |archive-date=December 24, 2019 |archive-url=https://web.archive.org/web/20191224214927/https://www.ukhat.org/aircraft-detail?aircraft=douglas-dc-3-dakota&id=12 |url-status=dead}} Only five were delivered, three of them to Capital Airlines.

A number of aircraft companies attempted to design a "DC-3 replacement" over the next three decades (including the very successful Fokker F27 Friendship), but no single type could match the versatility, rugged reliability, and economy of the DC-3. While newer airliners soon replaced it on longer high-capacity routes, it remained a significant part of air transport systems well into the 1970s as a regional airliner before being replaced by early regional jets.

Perhaps unique among prewar aircraft, the DC-3 continues to fly in active commercial and military service as of 2021, eighty-six years after the type's first flight in 1935, although the number is dwindling due to expensive maintenance and a lack of spare parts.{{Citation needed|date=January 2021|reason=The original version of this unsourced claim was made in the 5 May 2017 edit; although the AS OF date has since been updated a couple of times, there is no cited source for any date.}} There are small operators with DC-3s in revenue service and as cargo aircraft. Applications of the DC-3 have included passenger service, aerial spraying, freight transport, military transport, missionary flying, skydiver shuttling and sightseeing. There have been a very large number of civil and military operators of the DC-3/C-47 and related types, which would have made it impracticable to provide a comprehensive listing of all operators.
