The Caudron R.4 was a French World War I twin-engine biplane reconnaissance/artillery cooperation aircraft and the progenitor of a series of successful aircraft that filled a variety of roles with the French Aéronautique Militaire.
The Bergamaschi C-1 and C-2 were Italian single-engined light trainers built by Cantieri Aeronautici Bergamaschi for the Bergamo flying school.
The PZL P.1 was a Polish fighter, designed by the engineer Zygmunt Puławski, manufactured by the PZL state-owned factory. It remained a prototype, but it was the first of the Polish PZL gull wing fighter series, leading to the PZL P.7, PZL P.11 and PZL P.24.
The Bleriot-SPAD S.33 was a small French airliner developed soon after World War I. The aircraft was a biplane of conventional configuration whose design owed much to the Blériot company's contemporary fighter designs such as the S.20. Four passengers could be accommodated in an enclosed cabin within the monocoque fuselage, and a fifth passenger could ride in the open cockpit beside the pilot. A great success, the S.33 dominated its field throughout the 1920s, initially on CMA's Paris-London route, and later on continental routes serviced by Franco-Roumaine.
The CAMS 46 was a flying boat trainer aircraft built in France in the mid-1920s, essentially an updated version of the CAMS 30 that had flown in 1922. While retaining that aircraft's basic form, CAMS offered the French Navy two new versions with aerodynamic refinements over the earlier aircraft: the CAMS 46 E primary trainer, and the CAMS 46 ET intermediate trainer. Only the latter was selected for production and was built in quantity to supply one escadrille at the Naval training station at Hourtin.
The Caudron R.11, was a French three-seat twin-engine long range escort fighter biplane developed and produced by Caudron during the First World War.
The Fokker C.VIII was a reconnaissance aircraft built in the Netherlands in the late 1920s. Intended primarily for the photographic reconnaissance role, it was a larger machine than other Fokker reconnaissance types of the period, with space for a third crew member, who acted as camera operator. It was also Fokker's first aircraft of this type to be built as a monoplane, a parasol wing configuration. The construction, however, was in the familiar Fokker style with wooden wings covered with plywood and fabric, and a steel-tube fuselage, also fabric-covered.
The Goupy No.1, a.k.a. Goupy I bis was an experimental aircraft built in France during 1908, which on 5 September that year became the first French triplane to fly. It was designed by Ambroise Goupy and built by Aéroplanes Voisin.
The Gourdou-Leseurre GL.30 was a racing aircraft built in France in 1920 which formed the basis for a highly successful family of fighter aircraft based on the same design.
The Letord Let.5 was probably the most numerous of a family of 3-seat reconnaissance bombers, designed and built in France from 1916, originally to an A3 specification from the STAé.
The Nieuport 14 was a military reconnaissance sesquiplane produced in France during the First World War. The French Army deployed it in 1916 but the type was quickly withdrawn from front-line service.
The Sopwith B.1 was an experimental British bomber aircraft of the First World War. A single-seat, single-engined biplane, the B.1 was built by the Sopwith Aviation Company for the Royal Navy. Although only two were built, one was used for bombing raids over France.
The Tebaldi-Zari was an Italian fighter prototype of 1919. The Breda company later acquired the rights to it.
The Stampe et Vertongen RSV.22 was a training biplane produced in Belgium in the 1920s.
The Adolphe Bernard AB was a twin-engined French biplane aircraft, built near the end of the First World War. Ten AB 1 BN2 bombers were produced for the Armée de l'Air but did not reach squadron service; post-war, two civil derivatives were considered but only one aircraft was built.
The Port Victoria P.V.5 was a British single-engined floatplane fighter aircraft of the First World War. A single example was built and flown at the Royal Naval Air Service's Port Victoria Marine Experimental Aircraft Depot on the Isle of Grain in 1917. Despite demonstrating good manoeuvrability and handling, no production followed, with the Royal Naval Air Service instead using landplanes for the fighter role.
The Tellier T.2 was a French two-seat patrol biplane flying-boat built by Société Alphonse Tellier et Cie à Neuilly (hull) and Voisin (wings). The wooden-hull flying boat used a 150 kW (200 hp) Hispano-Suiza 8Ba engine and was first flown in June 1916.
The FBA Avion Canon was a two-seat cannon-armed biplane fighter, designed and built in France from 1916. due to unsatisfactory performance, development of the Avion Canon was abandoned.
The Potez XIX was a prototype French night bomber built by Potez in the 1920s.
The Voisin XII was a prototype French two-seat four-engine biplane bomber built near the end of the First World War but which did not enter service.
