The Curtiss C-46 Commando is a low-wing, twin-engine aircraft derived from the Curtiss CW-20 pressurised high-altitude airliner design. Early press reports used the name "Condor III" but the Commando name was in use by early 1942 in company publicity. It was used primarily as a cargo aircraft during World War II, with fold-down seating for military transport and some use in delivering paratroops. Mainly deployed by the United States Army Air Forces, it also served the U.S. Navy/Marine Corps, which called it R5C. The C-46 filled similar roles as its Douglas-built counterpart, the C-47 Skytrain, with some 3,200 C-46s produced to approximately 10,200 C-47s.
The Douglas DC-5 was a 16-to-22-seat, twin-engine propeller aircraft intended for shorter routes than the Douglas DC-3 or Douglas DC-4. By the time it entered commercial service in 1940, many airlines were canceling orders for aircraft. Consequently, only five civilian DC-5s were built. With the Douglas Aircraft Company already converting to World War II military production, the DC-5 was soon overtaken by world events, although a limited number of military variants were produced.
The Douglas Y1B-7 was a 1930s American bomber aircraft. It was the first US monoplane given the B- 'bomber' designation. The monoplane was more practical and less expensive than the biplane, and the United States Army Air Corps chose to experiment with monoplanes for this reason. At the time the XB-7 was ordered, it was being tested by Douglas Aircraft as an observational plane.
The Douglas YOA-5 was an Amphibious aircraft designed for the United States Army Air Corps. Although a prototype was built, it did not enter production.
The Douglas XB-19 was a four-engined, piston-driven heavy bomber produced by the Douglas Aircraft Company for the United States Army Air Forces (USAAF) during the early 1940s. The design was originally given the designation XBLR-2. It was the largest bomber built for the USAAF until 1946, with the Convair B-36 surpassing it in size.
The Douglas A2D Skyshark was an American turboprop-powered attack aircraft built by the Douglas Aircraft Company for the United States Navy. The program was substantially delayed by engine reliability problems, and was canceled because more promising jet attack aircraft had entered development and the smaller escort carriers the A2D was intended to utilize were being phased out.
The Douglas XB-31 was the design submitted by Douglas after the request by the United States Army Air Forces for a very heavy bomber aircraft, the same request that led to the Boeing B-29 Superfortress, Lockheed XB-30, and Consolidated B-32 Dominator.
The Douglas World Cruiser (DWC) was developed to meet a requirement from the United States Army Air Service for an aircraft suitable for an attempt at the first flight around the world. The Douglas Aircraft Company responded with a modified variant of their DT torpedo bomber, the DWC.
The Douglas XA-2 was an American prototype attack aircraft converted from a Douglas O-2 observation aircraft in the spring of 1926 by Douglas Aircraft. Only one prototype aircraft was built and the type was not ordered into production.
The Douglas O-38 was an observation airplane used by the United States Army Air Corps.
The Northrop A-17, also known as the Northrop Model 8, a development of the Northrop Gamma 2F model, was a two-seat, single-engine, monoplane, attack bomber built in 1935 by the Northrop Corporation for the United States Army Air Corps. When in British Commonwealth service during World War II, the A-17 was called Nomad.
The Douglas C-1 was a cargo/transport aircraft produced by the Douglas Aircraft Corporation for the United States Army Air Service starting in 1925.
The McDonnell 119/220 is a business jet developed and unsuccessfully marketed by McDonnell Aircraft in the late 1950s and early 1960s. Its configuration is unique for this type of aircraft, with four podded engines underneath a low wing. It is the only airplane built by McDonnell Aircraft to be marketed to civil buyers prior to the company's merger with Douglas Aircraft to form McDonnell Douglas. The jet could be outfitted for 10 passengers in a luxury executive configuration and could carry as many as 29.
The Heinkel He 46 was a German World War II-era monoplane designed in 1931 for the close reconnaissance and army co-operation roles. While it served with the Luftwaffe's front-line units only briefly at the start of World War II, the He 46 served as late as 1943 as a nighttime nuisance bomber and with the Hungarian Air Force.
The Douglas O-31 was the Douglas Aircraft Company's first monoplane observation straight-wing aircraft used by the United States Army Air Corps.
The Douglas O-43 was a monoplane observation aircraft used by the United States Army Air Corps.
The Douglas O-2 was a 1920s American observation aircraft built by the Douglas Aircraft Company, powered by the Liberty engine of WW1 fame, with some later variants using other engines. It was developed into several version, with 879 being produced in total. It was used in combat by the Chinese Air Force in the 1930s and also was that basis for a successful mailplane version.
The Douglas mailplanes were a family of 1920s American single-seat mail planes designed and built by the Douglas Aircraft Company. The aircraft were used to run the main routes of the United States Air Mail service until the introduction of three-engined aircraft in 1928.
The Northrop Delta was an American single-engined passenger transport aircraft of the 1930s. Closely related to Northrop's Gamma mail plane, 13 were produced by the Northrop Corporation, followed by 19 aircraft built under license by Canadian Vickers Limited.
The Douglas R4D-8 is a military transport aircraft developed from the civilian Douglas DC-3S airliner. It was used by the United States Navy and United States Marine Corps during the Korean War and Vietnam War.
