The IAR 12 is a Romanian low-wing monoplane fighter-trainer aircraft designed before World War II.
The failure of the first fighter designed at Brașov did not discourage the energetic team of the I.A.R. Works. Even before the second prototype of the C.V. 11 was disqualified from the fighter contest, the first details of its successor had already been laid out by Engineer-in-Chief Elie Carafoli. A new tail with enlarged rudder was fitted to essentially the same fuselage, giving a more conventional look and offering better control during flight. As a consequence, the overall height increased by more than a meter, i.e., 40% of the original dimension. Unlike the IAR 11 design, the wingtips were rounded, and the span had been increased as well, giving a 19.80 m2 (213.1 sq ft) wing area compared to the original 18.20 m2 (195.9 sq ft) of the C.V. 11. An anti-crash pylon with a minuscule Venturi-tube installed at its top appeared behind the cockpit to protect the pilot in case the aircraft overturned.
The powerplant chosen for the new aircraft, named I.A.R. 12, was again a Lorraine-Dietrich 12Eb, 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 (183 mph). This unsatisfactory result, combined with poor handling characteristics experienced during early test flights, constrained Carafoli to improve the construction and try a new engine, fitted to essentially the same fuselage, giving a more conventional look and offering better control during flight. An anti-crash pylon with a minuscule Venturi-tube installed at its top appeared behind the cockpit to protect the pilot in case the aircraft overturned. Such a feature on the C.V. 11 C1 could have saved the life of Cpt. Popescu on that fatal day in early December 1931.

The Avioane Craiova IAR-93 Vultur (Eagle) is a twinjet, subsonic, close support, ground attack and tactical reconnaissance aircraft with secondary capability as low level interceptor. Built as single-seat main attack version or combat capable two-seat version for advanced flying and weapon training, it was developed in 1970s by Romania and Yugoslavia to become more independent from Soviet equipment. The Romanian aircraft were built by I.R.Av. Craiova as IAR-93, and its Yugoslav counterpart by Soko as the Soko J-22 Orao. For Romania, the IAR-93 was intended to replace MiG-15s and MiG-17s in the fighter-bomber role.
The IAR 14 is a Romanian low-wing monoplane fighter-trainer aircraft designed before World War II.
The IAR 99Șoim (Hawk) is an advanced trainer and light attack aircraft capable of performing close air support and reconnaissance missions. The IAR 99 replaced the Aero L-29 Delfin and Aero L-39 Albatros as the jet trainer of the Romanian Air Force. The aircraft is of semi-monocoque design, with tapered wings and a swept-back tail unit. A large blade-type antenna installed beneath the nose on the port side of the fuselage gives the IAR 99 trainer a distinctive appearance.
The PWS-10 was a Polish fighter aircraft, constructed in the PWS. It was the first Polish-designed fighter to enter serial production.
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 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 IAR 15 was a low-wing monoplane fighter designed in Romania in 1933. Designed by Elie Carafoli for the Romanian Air Force, the IAR 15 was a lightly armed low-wing cantilever monoplane with a radial engine, fixed undercarriage and open cockpit.
The Vickers F.B.24 was a British two-seat fighter aircraft of the First World War. Only a few prototypes were built, as, although it had good performance, the Bristol F.2 Fighter was preferred.
The IAR-22 was a single engine basic trainer built in Romania in about 1934. It was a low-wing monoplane with two seats in tandem and a fixed conventional undercarriage.
The IAR 47 was a 1942 prototype aircraft built by Industria Aeronautică Română.

The Dewoitine D.25 was a single-engine, two-seat, parasol-wing fighter aircraft built in France in the 1920s. The 1925 French two-seat fighter programme was cancelled before any orders were placed, but four examples were exported to Argentina.
The Potez 26 was a single seat fighter aircraft designed and flown in France in the mid-1920s. It did not reach production.
The Caudron C.99 was a French light bomber and reconnaissance aircraft. The only example flew with different engines in the mid-1920s.
The Descamps 17 A.2 was a two-seat reconnaissance fighter built under a French government programme of 1923. Two versions, with different engines, were tested and six examples were built under licence by Caudron as the Caudron C.17 A.2.
The Villiers V, Villiers 5 or Villiers 5CN2 was a French night fighter built in the mid-1920s. It did not go into production.
The Morane-Saulnier MS.300 and MS.301 were French parasol wing introductory trainer aircraft, first flown in 1930. They differed only in engine type. Neither reached production but were developed into two similar trainers, the MS.230 and MS.315, which were made in large numbers.
