The Curtiss A-8 was a low-wing monoplane ground-attack aircraft built by the United States company Curtiss Aeroplane and Motor Company, designed in response to a 1929 United States Army Air Corps requirement for an attack aircraft to replace the A-3 Falcon. The Model 59 "Shrike" was designated XA-8.
The Douglas DC-4 is a four-engine (piston) propeller-driven airliner developed by the Douglas Aircraft Company. Military versions of the plane, the C-54 and R5D, served during World War II, in the Berlin Airlift and into the 1960s. From 1945, many civil airlines operated the DC-4 worldwide.
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 Keystone B-4 was a biplane bomber, built by the Keystone Aircraft company for the United States Army Air Corps.
The Keystone B-6 was a biplane bomber developed by the Keystone Aircraft company for the United States Army Air Corps.
The Douglas XB-19 was the largest bomber aircraft built for the United States Army Air Forces until 1946. It was originally given the designation XBLR-2.
The Douglas C-74 Globemaster was a United States heavy-lift cargo aircraft built by the Douglas Aircraft Company in Long Beach, California. The aircraft was developed after the Japanese attack on Pearl Harbor. The long distances across the Atlantic and, especially, Pacific oceans to combat areas indicated a need for a transoceanic heavy-lift military transport aircraft. Douglas Aircraft Company responded in 1942 with a giant four-engined design. Development and production modifications issues with the aircraft caused the first flight to be delayed until 5 September 1945, and production was limited to 14 aircraft when the production contract was canceled following V-J Day.
The Curtiss XA-14 was a 1930s United States airplane, the first multi-engine attack aircraft tested by the United States Army Air Corps. Carrying a crew of two, it was as fast as the standard pursuit aircraft in service at the time.
The Northrop Alpha was an American single-engine, all-metal, seven-seat, low-wing monoplane fast mail/passenger transport aircraft used in the 1930s. Design work was done at the Avion Corporation, which in 1929, became the Northrop Aircraft Corporation based in Burbank, California.
The Republic RC-3 Seabee is an all-metal amphibious sports aircraft designed by Percival Spencer and manufactured by the Republic Aircraft Corporation.
The Fokker F26 was an early jet airliner design by the Dutch aircraft manufacturer, Fokker.
The Nakajima Ki-34 was a Japanese light transport of World War II. It was a twin-engine, low-wing monoplane; the undercarriage was of tailwheel type with retractable main units. During the Pacific War, the Allies assigned the type the reporting name Thora.
The Waco CG-15 was an American military glider, which was developed from the CG-4. Although outwardly similar to its predecessor and carrying the same number of passengers, a number of changes in the design, including shortened wings and a more streamlined nose enabled it to travel faster. 1,000 were ordered and 473 were delivered before production ceased. Two were transferred to the Navy for testing as the XLR2W-1. One unit was converted into an XPG-3 powered glider which used two Jacobs R-755-9 radial engines.
The Waco CG-3A was a US light troop military glider of World War II.
The Waco CG-4A was the most widely used American troop/cargo military glider of World War II. It was designated the CG-4A by the United States Army Air Forces, and named Hadrian in British military service.
The Douglas XCG-17 was an American assault glider, developed by the conversion of a C-47 Skytrain twin-engine transport during World War II. Although the XCG-17 was successful in testing, the requirement for such a large glider had passed, and no further examples of the type were built; one additional C-47, however, was converted in the field to glider configuration briefly during 1946 for evaluation, but was quickly reconverted to powered configuration.
The Waco CG-13 was an American military transport glider aircraft developed during World War II.
The Nakajima Ki-19 was an unsuccessful attempt by Nakajima Aircraft Company to meet a 1935 requirement issued by the Japanese government for a modern bomber to replace the Mitsubishi Ki-1 heavy bomber.
The SNCAC Martinet was a German-designed but French-built twin-engined military trainer and light transport monoplane. It was operated by the French military and in small numbers by French airlines from the late 1940s.
The St. Louis CG-5 was a 1940s American prototype military transport glider designed and built by the St. Louis Aircraft Corporation.
