The Douglas DC-2 was a 14-seat, twin-propeller airliner produced by the Douglas Aircraft Corporation starting in 1934. It competed with the Boeing 247. In 1935 Douglas produced a larger version called the DC-3, which became one of the most successful airplanes in history.

Design and development

In the early 1930s, fears about the safety of wooden aircraft structures (responsible for the crash of a Fokker Trimotor) compelled the American aviation industry to develop all-metal types. With United Airlines having a monopoly on the Boeing 247, rival Transcontinental and Western Air issued a specification for an all-metal trimotor.

The response of the Douglas Aircraft Company was more radical. When it flew on July 1, 1933, the prototype DC-1 had a highly robust tapered wing, a retractable undercarriage, and only two 690 hp (515 kW) Wright radial engines driving variable-pitch propellers. It seated 12 passengers.

TWA accepted the basic design and ordered 20, with more powerful engines and seating for 14 passengers, as DC-2s. The design impressed a number of American and European airlines and further orders followed. Those for European customers KLM, LOT, Swissair, CLS and LAPE were assembled by Fokker in the Netherlands. 156 DC-2s were built.

Operational history

Although overshadowed by its ubiquitous successor, it was the DC-2 which first showed that passenger air travel could be comfortable, safe and reliable. As a token of this, KLM entered their first DC-2 PH-AJU Uiver (Stork) in the October 1934 MacRobertson Air Race between London and Melbourne. Out of the 20 entrants, it finished second behind only the purpose built de Havilland DH.88 racer Grosvenor House. During the total journey time of 90 h 13 min, it was in the air for 81 h 10 min, and won the handicap section of the race. (The DH.88 finished first in the handicap section, but the crew was by regulations allowed to claim only one victory.)

Variants

DC-2A
Two civil DC-2s, powered by two Pratt & Whitney R-1690 "Hornet" radial piston engines.
DC-2B
Two DC-2s sold to LOT Polish Airlines, fitted with two Bristol Pegasus VI radial piston engines.

Modified DC-2s built for the United States Army Air Corps under several military designations:

XC-32
16-seat transport aircraft, later a flying command post, 1 built.
C-32A
Designation for 24 commercial DC-2s impressed at the start of World War II.
C-33
Cargo transport aircraft, with a hinged cargo door in the aft fuselage, 18 built.
YC-34
VIP transport, later designated C-34, 2 built.
C-38
The first C-33 was modified with a DC-3 style tail section and two Wright R-1820-45 radial piston engines of 930 hp (694 kW) each. Originally designated C-33A but redesignated as prototype for C-39 variant. 1 built.
C-39
A composite of DC-2 & DC-3 components. Powered by two Wright R-1820-55 radial piston engines, of 975 hp (727 kW) each, 35 built.
C-41/C-41A
VIP transport powered by two Pratt & Whitney R-1830-21 radial piston engines, of 1,200 hp (895 kW) each, 1 of each built. The C-41 was the staff plane of Maj. Gen. Henry H. Arnold and the C-41A was used to fly the Secretary of War.
C-42
VIP transport, Powered by two Wright R-1820-53 radial piston engines, of 1200 hp (895 kW) each. 1 built in 1939 for the commanding general, GHQ Air Force, plus two similarly-converted C-39s procured in 1943.
R2D
One transport aircraft for the US Navy.
R2D-1
Four transport aircraft for the US Navy.
Nakajima AT-2 / Ki-34
Japanese license-built version
