The IAR 13 is a Romanian low-wing monoplane fighter-trainer aircraft designed before World War II.
The powerplant for IAR 12, was an IAR LD 450 12-cylinder W-form watercooled in-line built under license Lorraine-Dietrich 12 Eb, that offered 450 h.p. (336 kW) at 1,900 r.p.m., similar to the type fitted to the first C.V. 11. However, due to the increased aerodynamic drag, the maximum speed at ground level decreased to 294 km/h. This unsatisfactory result, combined with poor handling characteristics experienced during early test flights, constrained Carafoli to improve the construction and try a new engine. [1]
The new project, called I.A.R. 13, was essentially similar to the abandoned '12', except for the fin-and-rudder. Its surface had been reduced and instead of a rounded shape it became oval. The fuselage, wings and the anti-crash pylon had all been retained, while the undercarriage suffered minor changes. The engine fitted to the airframe was a Hispano-Suiza 12Mc of 500 h.p. (373 kW) output at 2,200 r.p.m. that operated a two-blade, all-metal Ratier propeller. The more powerful engine helped to boost the top speed to 330 km/h, which meant a significant 12% increase. The overall flying characteristics were improved as well. Nevertheless, these significant results and the demonstration flights performed by Locotenent aviator Eugen "Puiu" Pârvulescu in 1933 did not impress the senior ARR leaders, still resistant to the new idea of a low-wing monoplane fighter.

The IAR 14 is a Romanian low-wing monoplane fighter-trainer aircraft designed before World War II.
Potez 25 was a French twin-seat, single-engine biplane 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 Avia B.35 was a fighter aircraft built in Czechoslovakia shortly before World War II.
The Nieuport-Delage NiD.62 was a French sesquiplane fighter from the early 1930s. This machine was a descendant of a long line of Nieuport-Delage fighters that were designed and built during the years immediately after World War I. The NiD.62 was built in 1931 as a fighter for the Armée de l'Air. It served until the late 1930s, when it was replaced by more modern monoplane fighters. By the time of the outbreak of World War II in September 1939, all of the NiD.62s had been withdrawn from front-line fighter escadrilles but were used as trainers in French flight schools. A few aircraft were employed as target tugs. After the French German Armistice and German occupation of North and West part of France in June 1940, the German Luftwaffe had no interest in the NiD.62s and they were scrapped. None survived the war.
The Dewoitine D.1 was a French single-seat fighter aircraft of the 1920s, built by the French industrial company Dewoitine.
The IAR CV 11 was a Romanian fighter prototype in 1930, designed by Elie Carafoli, and it was IAR's first original aircraft.
The Latécoère 32 was a flying boat built in France in 1928 for use on Aéropostale's mail routes to North Africa.
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 IAR 15 was a low-wing monoplane fighter designed in Romania in 1933.
The IAR-23 and IAR-24 were low-wing monoplane light multipurpose aircraft with a conventional undercarriage, built by IAR of Romania.
The SNCAO 200, sometimes written CAO.200, was a prototype French single seat fighter aircraft of the 1930s. It was a single engined monoplane intended to compete with the Dewoitine D.520, but was unsuccessful, only a single example being built.
The Nieuport-Delage NiD 120 series was a series of French single-seat parasol monoplane fighter aircraft of the 1930s. It was built in a number of versions, fitted with various types of engines, with six aircraft designated NiD 123 being sold to Peru.
The Romano R.90 was a prototype single-seat French floatplane fighter of the 1930s. A single example of the R.90 was built, but the type did form the basis of the Romano R.83 and Romano R.92 fighters which were built in secret for the Spanish Republicans during the Spanish Civil War.

The Wibault 13C.1 Trombe (Whirlwind), later known as the Wib 130C.1 Trombe was a single seat, parasol wing lightweight fighter aircraft designed and built in France in the 1920s. It was developed into the more powerful Wib 170C.1 Tornade (Tornado) but government interest in lightweight fighters soon waned.
The Potez 230 was a French lightweight single-seat, single-engined fighter aircraft. One prototype was built and flew in 1940, but no production followed, with the prototype being captured and shipped to Germany for study.
The Blériot-SPAD S.91 was a French light-weight fighter aircraft. It would be later developed into the Blériot-SPAD S.510, the last biplane produced by the French aeronautic industries.
