The Sopwith Pup is a British single-seater biplane fighter aircraft built by the Sopwith Aviation Company. It entered service with the Royal Naval Air Service and the Royal Flying Corps in the autumn of 1916. With pleasant flying characteristics and good manoeuvrability, the aircraft proved very successful. The Pup was eventually outclassed by newer German fighters, but it was not completely replaced on the Western Front until the end of 1917. Remaining Pups were relegated to Home Defence and training units. The Pup's docile flying characteristics also made it ideal for use in aircraft carrier deck landing and takeoff experiments and training.
The Avro 504 was a First World War biplane aircraft made by the Avro aircraft company and under licence by others. Production during the war totalled 8,970 and continued for almost 20 years, making it the most-produced aircraft of any kind that served in any military capacity during the First World War. More than 10,000 were built from 1913 until production ended in 1932.
The Seversky P-35 is an American fighter aircraft built by the Seversky Aircraft Company in the late 1930s.

The North American F-107 is North American Aviation's entry in a United States Air Force tactical fighter-bomber design competition of the 1950s. The F-107 was based on the F-100 Super Sabre, but included many innovations and radical design features, notably the over-fuselage air intakes. The competition was eventually won by the Republic F-105 Thunderchief, and most of the F-107 prototypes ended their lives as test aircraft. One is on display at the National Museum of the United States Air Force and a second at Pima Air and Space Museum.
The North American P-64 was the designation assigned by the United States Army Air Corps (USAAC) to the North American Aviation NA-68 fighter, an upgraded variant of the NA-50 developed during the late 1930s. Seven NA-50s were purchased by the Peruvian Air Force, which nicknamed it Torito.
The Consolidated P-30 (PB-2) was a 1930s United States two-seat fighter aircraft. An attack version called the A-11 was also built, along with two Y1P-25 prototypes and YP-27, Y1P-28, and XP-33 proposals. The P-30 is significant for being the first fighter in United States Army Air Corps service to have retractable landing gear, an enclosed and heated cockpit for the pilot, and an exhaust-driven turbo-supercharger for altitude operation.
The Nieuport 28 C.1, a French biplane fighter aircraft flown during World War I, was built by Nieuport and designed by Gustave Delage. Owing its lineage to the successful line of sesquiplane fighters that included the Nieuport 17, the Nieuport 28 continued a similar design philosophy of a lightweight and highly maneuverable aircraft.
The Consolidated PT-1 Trusty was a biplane primary trainer used by the United States Army Air Service (USAAS).
The Morane-Saulnier M.S.225 was a French fighter aircraft of the 1930s. It was produced in limited quantities to be used as a transitional aircraft between the last of the biplanes and the first monoplane fighters.
The Curtiss 18T, unofficially known as the Wasp and by the United States Navy as the Kirkham, was an early American triplane fighter aircraft designed by Curtiss for the US Navy.
Potez 62 was a French twin-engine civil airliner, designed by Henry Potez in 1934. The French military adapted this air-frame two-years later to create the Potez 650.
The Curtiss R3C is an American racing aircraft built in landplane and floatplane form. It was a single-seat biplane built by the Curtiss Aeroplane and Motor Company.
The Thomas-Morse S-4 Scout was an American biplane advanced trainer, operated by the United States Army and the United States Navy. Dubbed the "Tommy" by pilots who flew it, the aircraft became the favorite single-seat training airplane produced in the U.S. during World War I. It had a long and varied career beginning with the S-4B, which first appeared in the summer of 1917.
The Morane-Saulnier AI was a French parasol-wing fighter aircraft produced by Morane-Saulnier during World War I.
The Wibault 7 was a 1920s French monoplane fighter designed and built by Société des Avions Michel Wibault. Variants were operated by the French and Polish military and built under licence for Chile as the Vickers Wibault.
The Thomas-Morse R-5 also known as the TM-22 was an American single-engined parasol monoplane racing aircraft of the 1920s. Two were built for the United States Army Air Service in 1922, but after competing in the 1922 Pulitzer Trophy Race the type was abandoned.
The Thomas Morse MB-9 was an experimental American fighter aircraft of the 1920s. It was a single-engined, single-seat parasol winged monoplane, but was unsuccessful, being quickly abandoned.
The Vought V-141 was a prototype American single-seat fighter aircraft of the 1930s. It was a development of the unsuccessful Northrop 3-A design, but was itself a failure, being rejected by the United States Army Air Corps. The sole prototype was sold to the Japanese Army in 1937, but no production followed, with the type proving to be inferior to existing Japanese fighters.
The Orenco B was a prototype American fighter aircraft of World War I. It was a single-engined, single-seat biplane that flew in 1918. Although it demonstrated good performance, it did not enter large scale service.
The Albree Pigeon-Fraser was the first pursuit aircraft project for the United States Government.
