The Aero A.12 was a Czechoslovakian biplane light bomber and military reconnaissance aircraft manufactured in small numbers shortly after World War I. Although reminiscent of the Hansa-Brandenburg-designed aircraft that Aero was building during the war under licence as the Ae.10, the A.12 was the company's own design. It is perhaps most significant as the direct descendant of the highly successful A.11 and its various derivatives. An example of the type is preserved at the Letecké Muzeum in Kbely.
The Aero A.100 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia during the 1930s. It was the final step in a design lineage that extended back to the Aero A.11 a decade earlier. A.100s remained in service throughout World War II and for a few years postwar.
The Aero A.101 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia during the 1930s.
The Breguet 19 was a sesquiplane bomber and reconnaissance aircraft which was also used for long-distance flights and was designed by the French Breguet company and produced from 1924.
The WZ.X was the Polish reconnaissance aircraft designed in the mid-1920s and manufactured in the Centralne Warsztaty Lotnicze (CWL) - Central Aviation Workshops in Warsaw. It was the first combat aircraft of own design built in Poland, in a small series.
Potez 25 was a French twin-seat, single-engine sesquiplane designed during the 1920s. A multi-purpose fighter-bomber, it was designed as a line aircraft and used in a variety of roles, including fighter and escort missions, tactical bombing and reconnaissance missions. In the late 1920s and early 1930s, Potez 25 was the standard multi-purpose aircraft of over 20 air forces, including French and Polish. It was also popular among private operators, notably mail transport companies.
The Letov Š-16 was a Czechoslovak single-engined, two-seat biplane bomber. It was designed by Alois Šmolík at Letov Kbely. The Š-16 first flew in 1926.
The Breda A.7 was a reconnaissance aircraft developed in Italy for use by the Regia Aeronautica in 1929. It was a braced parasol monoplane of conventional configuration with tailskid undercarriage. The pilot and observer sat in tandem, open cockpits. A single prototype of a long-range example, originally designated A.7 Raid and later A.16 was also constructed, but the air force showed no interest in it.
The Caproni Ca.97 was a civil utility aircraft produced in Italy in the late 1920s and early 1930s. As originally designed, it was a high-wing braced trimotor monoplane of conventional configuration with one engine mounted on the nose and the other two carried on strut-mounted nacelles at the fuselage sides. Examples were also produced with only the nose engine or only the two nacelle-mounted engines.
The Savoia-Marchetti S.59 was a 1920s Italian reconnaissance/bomber flying boat designed and built by Savoia-Marchetti for the Regia Aeronautica.
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 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 Potez 39 was a French two-seat single-engined parasol wing monoplane reconnaissance and observation aircraft of the 1930s.
The Levasseur PL.5 was a carrier-based fighter produced in France in the late 1920s, in response to the 1924 AMBC.2 specification issued by the Service Technique de l'Aéronautique (STAé). It was a conventional, single-bay sesquiplane that carried a crew of two in tandem, open cockpits. Like other Levasseur naval designs of the day, it incorporated several safety features in case of ditching at sea. Apart from small floats attached directly to the undersides of the lower wing, the main units of the fixed, tail-skid undercarriage could be jettisoned in flight, and the underside of the fuselage was given a boat-like shape and made watertight.
The Nieuport-Delage NiD 42 was a fighter aircraft built in France in the early 1920s, the first in a family of designs that would form the backbone of the French fighter force over the next decade.
The Yokosuka E5Y was a single-engine Japanese seaplane used for reconnaissance. The E5Y was also built by Kawanishi as the E5K
The Breda A.14 was a prototype three-engined biplane, designed by Società Italiana Ernesto Breda as a night bomber in 1928.
The Breda A.8 was a prototype twin-engined biplane, designed by Società Italiana Ernesto Breda, as a night bomber in 1927.
The Fizir F1V was the basis from which engineer Rudolf Fizir developed a series of single-engined, two-seat, reconnaissance biplanes fitted with different engines. Construction was carried out in the Yugoslav aircraft factories Zmaj and Rogožarski between 1928 and 1932.
The Nieuport-Delage NiD 540 was a high wing, eight seat, single engine airliner, built in France and first flown in 1930. It did not reach production.
