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. The 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 Sopwith 1+1⁄2 Strutter is a British single- or two-seat multi-role biplane aircraft of the First World War. It was the first British two-seat tractor fighter and the first British aircraft to enter service with a synchronised machine gun. It was given the name 1+1⁄2 Strutter because of the long and short cabane struts that supported the top wing. The type was operated by both British air services and was in widespread but lacklustre service with the French Aéronautique Militaire.
The Sopwith Tabloid and Sopwith Schneider (floatplane) were British biplanes, originally designed as sports aircraft and later adapted for military use. They were among the first successful types to be built by the Sopwith Aviation Company. The "Tabloid", so named because of its small size, caused a sensation when it made its first public appearance.
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 Armstrong Whitworth F.K.3 was a British two-seat general-purpose biplane built by Armstrong Whitworth Aircraft during the First World War. By the end of the war it was considered obsolete for combat.
The Armstrong Whitworth F.K.8 was a British two-seat general-purpose biplane built by Armstrong Whitworth during the First World War. The type served alongside the better known R.E.8 until the end of the war, at which point 694 F.K.8s remained on RAF charge.
The Airco DH.5 was a British First World War single-seat biplane fighter aircraft. It was designed and manufactured at British aviation company Airco. Development was led by aircraft designer Geoffrey de Havilland as a replacement for the obsolete Airco DH.2.
The Royal Aircraft Factory B.E.12 was a British single-seat aeroplane of The First World War designed at the Royal Aircraft Factory. It was essentially a single-seat version of the B.E.2.
The Green Engine Co was a British engine company founded by Gustavus Green in Bexhill to sell engines of his design. He flourished especially as a designer of aeroplane engines during the first two decades of the 20th century. The engines were actually manufactured by the Aster Engineering Company.
The Armstrong Whitworth Armadillo was a British single-seat biplane fighter aircraft built by Armstrong Whitworth.
The Sopwith Snapper was a prototype British fighter aircraft of the First World War. A single-engined biplane designed by the Sopwith Aviation Company to replace the Sopwith Snipe fighter, it first flew after the end of the war, but did not enter service owing to the failure of its engine, only three aircraft being built.
The BAT F.K.25 Basilisk was a prototype British fighter aircraft of the First World War. A single engined biplane intended to meet a requirement to replace the Sopwith Snipe, the Basilisk was unsuccessful, only three being built.
The Armstrong Whitworth F.K.5 and F.K.6 were experimental triplanes built as escort fighters by Armstrong Whitworth during the First World War. They carried two gunners in nacelles mounted on the centre wing. One example of each type was built, with no further development or production following.
The Vickers F.B.11 was a prototype British three-seat escort fighter of the First World War. A large single-engined biplane, it carried one gunner in a nacelle mounted on the upper wing to give an allround field of fire. Only a single example was completed.
The Sopwith Long Range Tractor Triplane (L.R.T.Tr) was a prototype British long-range three-seat triplane escort fighter of the First World War. Its unusual layout had a small gunner's nacelle mounted on the upper wing for an all-round field of fire. Only a single example was built, as other, smaller fighters proved more practicable.
The Sopwith Gunbus was a British fighter aircraft of the First World War. It was a single-engined pusher biplane based on a floatplane built by Sopwith before the war for Greece. Small numbers were built and used by the British Royal Naval Air Service, mainly as a trainer.
The Sopwith Three-seater was a British aircraft designed and built prior to the start of the First World War. One of the first aircraft built by the Sopwith Aviation Company, it was operated by both the Royal Naval Air Service (RNAS) and the Royal Flying Corps (RFC), being used briefly over Belgium by the RNAS following the start of the War.
The Curtiss C-1 Canada was a twin-engined bomber aircraft of the First World War which was designed by Curtiss of America to be built by their Canadian subsidiary for the British Royal Naval Air Service and Royal Flying Corps. Although large orders were placed, only twelve were built, the type being rejected in favour of more capable aircraft such as the Handley Page O/100.
The Royal Aircraft Factory B.E.3 was a single-engined rotary engined biplane developed by the British Royal Aircraft Factory prior to the First World War. The B.E.4 and B.E.7 were virtually identical aircraft that differed only in the engine fitted.
