The Curtiss B-2 Condor was a 1920s United States bomber aircraft. It was a descendant of the Martin NBS-1, which was built by the Curtiss Aeroplane and Motor Company for the Glenn L. Martin Company. There were a few differences, such as stronger materials and different engines, but they were relatively minor.
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 Sopwith 1+1⁄2 Strutter was 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 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 Airco DH.4 is a British two-seat biplane day bomber of the First World War. It was designed by Geoffrey de Havilland for Airco, and was the first British two-seat light day-bomber capable of defending itself.
The Felixstowe F.2 was a 1917 British flying boat class designed and developed by Lieutenant Commander John Cyril Porte RN at the naval air station, Felixstowe during the First World War adapting a larger version of his superior Felixstowe F.1 hull design married with the larger Curtiss H-12 flying boat. The Felixstowe hull had superior water contacting attributes and became a key base technology in most seaplane designs thereafter.
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 Airco DH.1 was an early military biplane of typical "Farman" pattern flown by Britain's Royal Flying Corps during World War I. By the time the powerplant for which it was designed was sufficiently plentiful it was obsolete as an operational aircraft, and apart from a few examples sent to the Middle East it served as a trainer and Home Defence fighter.
The Nieuport 12 was a French sesquiplane reconnaissance, fighter aircraft and trainer used by France, Russia, Great Britain and the United States during World War I. Later production examples were built as trainers and served widely until the late 1920s.
The Curtiss Model H was a family of classes of early long-range flying boats, the first two of which were developed directly on commission in the United States in response to the £10,000 prize challenge issued in 1913 by the London newspaper, the Daily Mail, for the first non-stop aerial crossing of the Atlantic. As the first aircraft having transatlantic range and cargo-carrying capacity, it became the grandfather development leading to early international commercial air travel, and by extension, to the modern world of commercial aviation. The last widely produced class, the Model H-12, was retrospectively designated Model 6 by Curtiss' company in the 1930s, and various classes have variants with suffixed letters indicating differences.
The Norman Thompson N.T.4 was a twin-engined British flying boat of the First World War. Although less well known than similar Curtiss and Felixstowe flying boats, 50 were ordered for Britain's Royal Naval Air Service.
The Curtiss Model R was a utility aircraft produced for the United States Army and Navy during World War I. It was a conventional, two-bay biplane with slightly staggered wings of unequal span. The aircraft was provided with two open cockpits in tandem and fixed tailskid undercarriage, but many were built for the Navy with twin floats replacing the wheels. During the course of the war, Model Rs were used for general liaison and communication duties, as well for observation, training, and as air ambulances. In practice, the Curtiss powerplants supplied with these aircraft proved insufficient and were mostly replaced with Liberty engines. The Navy's Model R-3 floatplane had extended-span, three-bay wings, and was intended for use as a torpedo bomber. Some of these were later fitted with wheeled undercarriage and transferred to the Army as bombers under the designation Model R-9.
The Curtiss Model 55 Kingbird was an airliner built in small numbers in the United States in the early 1930s. It was a twin-engine aircraft with a fuselage derived from the single-engine Curtiss Thrush. The Kingbird had two engine nacelles mounted on the struts on either side of the fuselage that braced the wing and the outrigger undercarriage. A distinctive design feature was the aircraft's blunt nose, located behind the propeller arcs. This allowed the engines to be mounted closer to each other and to the aircraft's centerline, therefore minimising asymmetrical thrust in case of an engine failure. For the same reason, the Thrush's single tailfin was replaced by twin tails on the Kingbird, and the main production model, the D-2 fitted a second horizontal stabilizer and elevator between these fins.
The Royal Aircraft Factory B.E.8 was a British two-seat single-engined general purpose biplane of the First World War, designed by John Kenworthy at the Royal Aircraft Factory in 1913. Small numbers were used by the Royal Flying Corps over the Western Front in the first year of the war, with the type being used as a trainer until 1916.
The White and Thompson No. 3 was a British flying boat of the First World War. While the prototype was originally designed to compete in an air-race around the UK, eight more similar aircraft were built for the Royal Naval Air Service.
The Royal Aircraft Factory N.E.1 was a prototype British Night fighter of the First World War. A single-engined pusher biplane, it was a development of the Royal Aircraft Factory's earlier F.E.9 fighter, but was not successful, only six being built.
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 Dunne D.8 of 1912 was a tailless swept wing biplane, designed by J. W. Dunne to have inherent stability. One example was supplied to RAE Farnborough. License-built Burgess-Dunne models were used by the US Signal Corps and United States Navy and the short-lived Canadian Aviation Corps. It was the latter's first and only warplane.
The Wanamaker Triplane or Curtiss Model T, retroactively renamed Curtiss Model 3 was a large experimental four-engined triplane patrol flying boat of World War I. It was the first four-engined aircraft built in the United States. Only a single example (No.3073) was completed. At the time, the Triplane was the largest seaplane in the world.
The Curtiss CT-1 model 24, a twin engine torpedo bomber mounted on floats, was first flown in 1921.
