Between 1911 and 1914, the Royal Aircraft Factory used the F.E.2 designation for three quite different aircraft that shared only a common "Farman" pusher biplane layout.
The Vickers F.B.5 was a British two-seat pusher military biplane of the First World War. Armed with a single .303 in (7.7 mm) Lewis gun operated by the observer in the front of the nacelle, it was the first aircraft purpose-built for air-to-air combat to see service, making it the world's first operational fighter aircraft.
The Voisin III was a French World War I two-seat pusher biplane multi-purpose aircraft developed by Voisin in 1914 as a more powerful version of the 1912 Voisin L. It is notable for being the aircraft used for the first successful shooting down of an enemy aircraft on October 5, 1914, and to have been used to equip the first dedicated bomber units, in September 1914.
The Le Rhône 9C is a nine-cylinder rotary aircraft engine produced in France by Société des Moteurs Le Rhône / Gnome et Rhône. Also known as the Le Rhône 80 hp in a reference to its nominal power rating, the engine was fitted to many military aircraft types during the First World War. Le Rhône 9C engines were also produced under license in Great Britain, the United States and Sweden.
The Maurice Farman MF.7 Longhorn is a French biplane developed before World War I which was used for reconnaissance by both the French and British air services in the early stages of the war before being relegated to service as a trainer.
The Royal Aircraft Factory F.E.8 was a British single-seat fighter of the First World War designed at the Royal Aircraft Factory. It could not escape the drag penalty imposed by its tail structure and was no match for the Albatros fighters of late 1916.
The Voisin V was a French pusher-type bomber aircraft of World War I.
The Pemberton-Billing P.B.25 was a First World War British single-seat scout aircraft built by Pemberton-Billing Limited, later Supermarine Aviation Works Limited.
The SPAD S.A was a French two-seat tractor biplane first flown in 1915. It was used by France and Russia in the early stages of the First World War in the fighter and reconnaissance roles. It was a unique aircraft that carried its observer in a nacelle ahead of wing, engine and propeller.
The Farman III, also known as the Henry Farman 1909 biplane, was an early French aircraft designed and built by Henry Farman in 1909. Its design was widely imitated, so much so that aircraft of similar layout were generally referred to as being of the "Farman" type.
The Farman HF.20 and its derivatives were a family of reconnaissance aircraft produced in France shortly before and during the First World War. It was a refined version of the Farman MF.11 "Shorthorn" that did away with the type's distinctive landing skids, and incorporated design features from Henri Farman's designs. It entered service with the French, Belgian and Serbian armies in 1913, and with the British RFC and RNAS shortly after the outbreak of war. The type was also licence-built in the UK by Airco and Grahame-White.
The Vickers F.B.12 was a biplane pusher fighter aircraft developed during World War I by Vickers Limited. The failure of the engine for which it was designed, and the obsolescence of the pusher configuration, resulted in its remaining an experimental type only.
The Caudron J Marine was an amphibious, two-seat, biplane equipped with floats and wheels, similar to the earlier Caudron J floatplane.
The Short S.27 and its derivative, the Short Improved S.27, were a series of early British aircraft built by Short Brothers. They were used by the Admiralty and Naval Wing of the Royal Flying Corps for training the Royal Navy's first pilots as well as for early naval aviation experiments. An Improved S.27 was used by C.R. Samson to make the first successful take-off from a moving ship on 9 May 1912.
The Voisin Type de Course was an early French aircraft built by Voisin Frères. It was first flown early in 1910.
The Voisin Type Bordeaux was an aircraft built by Voisin Frères in 1910, so named because it was used by Juan Bielovucic to make a record-breaking flight from Paris to Bordeaux in France. The design differed significantly from previous Voisin designs in eliminating the forward-mounted elevator.
The Caudron Type C was a single seat French biplane, intended for military evaluation. Two were built in 1911.
The Farman HF.14 was a French two seat reconnaissance type produced by Farman Aviation Works before World War I.
The Voisin IV was a French two-seat bomber and ground attack aircraft of World War I.
The Farman HF.16 was a reconnaissance aircraft built in France shortly before the First World War. Aircraft of this type were also produced under license in the Russian Empire and served with the Imperial Russian Air Service during World War One.
