The Thulin K was a Swedish naval fighter aircraft in the 1910s. It was operated by both the Swedish and Dutch armed forces.
Dr. Enoch Thulin, of AB Thulinverken, designed the Thulin K in December 1916. It was a shoulder-wing monoplane of wooden construction employing wing warping for lateral control. Powered by a 90 hp Thulin A Gnôme derived rotary engine, it could be configured as a single seat or tandem seat aircraft.
After initial flights in early 1917, the Swedish Army purchased two of the single seat K versions. However, it was more successful as an export plane; the Royal Netherlands Navy bought twelve Ks between 1917 and 1918 and three Thulin KAs. Both types were delivered without armament but the Dutch Navy fitted theirs with machine guns firing through the propeller arc and also experimented with 20 mm Madson cannons.
The aircraft's performance was good - Thulin himself broke the Swedish altitude record in it in 1919. However, on 14 May 1919 [ citation needed ]Thulin's own Thulin K lost an aileron in a steep dive, crashing and killing him. The rest of the Thulin Ks were written off in 1920 and the Thulin KAs were withdrawn in 1922.

The Sopwith Pup was a British single-seater biplane fighter aircraft built by the Sopwith Aviation Company. It entered service with the Royal Flying Corps and the Royal Naval Air Service 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.
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 the First World War, in any military capacity, during that conflict. More than 10,000 were built from 1913 until production ended in 1940.
The Bell XFL Airabonita was an experimental carrier-based interceptor aircraft developed for the United States Navy by Bell Aircraft Corporation of Buffalo, New York. It was similar to and a parallel development of the U.S. Army Air Corps’ land-based P-39 Airacobra, differing mainly in the use of a tailwheel undercarriage in place of the P-39's tricycle gear. Only one prototype was manufactured.
The Sopwith Baby was a British single-seat tractor seaplane used by the Royal Naval Air Service (RNAS) from 1915.
The Thulin LA was a Swedish two-seat, single-engine biplane designed by Enoch Thulin in 1917 and made by his company AB Thulinverken in Landskrona. It was based on the earlier Thulin L and E aircraft, with a new engine, fuselage and empennage. The L and E types were in turn based on the German Albatros B.II aircraft, like the NAB Albatros. The Thulin LA was used in Sweden, the Netherlands (10) and Finland (1). This type also made the first passenger transport flights between Sweden and Denmark in 1919. Altogether there were 15 Thulin LAs built.
The Vickers F.B.19 was a British single-seat fighting scout of the First World War, developed from the Barnwell Bullet prototype, and sometimes known as the Vickers Bullet.

It never saw service in World War I, but Anthony Fokker managed to smuggle parts out of Germany at the time of the Armistice.
The Nightjar was a British carrier-based fighter aircraft of the early 1920s. It was a modification of the earlier Nieuport Nighthawk fighter produced by Gloster after the Nieuport & General company, which designed the Nighthawk, closed down. Twenty-two were converted, serving with the British Royal Air Force from 1922 to 1924.
The Gloster Sparrowhawk was a British single-seat fighter aircraft of the early 1920s. A development by Gloster Aircraft Company of the earlier Nieuport Nighthawk fighter, 50 aircraft were built by Gloster for the Imperial Japanese Navy, with a further 40 being assembled in Japan, being operated from 1921 to 1928.
The Nieuport-Delage NiD.29 was a French single-seat biplane fighter designed and built by Nieuport-Delage for the French Air Force.

The Sopwith 2FR.2 Bulldog was a prototype British two-seat fighter of the First World War. A single-engined biplane, the Bulldog was a fighter/reconnaissance aircraft intended to replace the Bristol F.2 Fighter, but was unsuccessful, with no replacement for the Bristol Fighter being purchased.
The Tupolev I-14 was a Soviet fighter aircraft of the 1930s. It was a single-engined, single-seat monoplane with retractable undercarriage, designed to carry heavy armament, and as such was one of the most advanced fighters of its time. It was ordered into production, but this was cancelled after only a small number had been built, the competing Polikarpov I-16 being preferred.
The Spijker V.2, sometimes anglicized to Spyker V.2 or Spyker-Trompenburg V.2, was a low powered, tandem seat biplane designed and built for the Dutch government for pilot training towards the end of World War I. More than seventy were built.
