The 12Z, designated Type 89 by the company, was the final production evolution of the series of Hispano-Suiza V-12 aircraft engines. The Z model was in the middle of development when France fell to the Germans during World War II. A small number were produced before and during the war but following the occupation of Vichy France, the German occupation government did not allow full-scale production to start. After the war development would resume and small numbers were built to equip new designs, but the rapid introduction of the jet engine ended further development.
The Breguet XIV or Breguet 14 is a French biplane bomber and reconnaissance aircraft of World War I. It was built in very large numbers and production continued for many years after the end of the war.
The Lublin R-VIII was a Polish bomber, reconnaissance aircraft and seaplane designed in the late 1920s by the Plage i Laśkiewicz factory in Lublin. It was the first in-house design of Plage i Laśkiewicz, and the first with the name Lublin.
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 Blériot-SPAD S.61 was a French fighter aircraft developed in 1923. Designed by André Herbemont, the S.61 was a conventional biplane, abandoning the swept upper wing used by Herbemont in several previous designs. The prototype S.61 was evaluated by the French Air Force alongside the S.51 as a potential new fighter, but like its stablemate, was rejected. The Polish Air Force was impressed enough to order 250, as well as purchase licences for local production. The Romanian Air Force also ordered 100 aircraft. About 30 were built in Poland, by the CWL.
The Bréguet 280T was a French biplane airliner of the late 1920s, created by the manufacturer as a means of finding a civil market for their 19 warplane, as they had once tried before with the 26T.
The Bréguet 270 was a sesquiplane military reconnaissance aircraft designed and produced by the French aircraft manufacturer Breguet.
The Dewoitine D.1 was a French single-seat fighter aircraft of the 1920s, built by the French industrial company Dewoitine.
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 29 was a 1920s French passenger biplane designed and built by Avions Henry Potez. Although designed as a civilian aircraft, a large number entered service with the French Air Force.
The SPAD S.XI or SPAD 11 is a French two-seat biplane reconnaissance aircraft of the First World War. The SPAD 11 was the work of Louis Béchereau, chief designer of the Société Pour L'Aviation et ses Dérivés (SPAD), who also designed the highly successful SPAD 7 and SPAD 13 single-seat fighter aircraft. It was developed under military specification C2, which called for a two-seat fighter aircraft. As a result of its failure to meet the levels of performance and agility demanded by the C2 specification, the SPAD 11 was used, along with the more successful Salmson 2 and Breguet 14, to replace ageing Sopwith 1½ Strutter and Dorand AR reconnaissance aircraft. Persistent problems with the SPAD 11 led to its early replacement by the SPAD S.XVI or SPAD 16 variant.
The Lioré et Olivier LéO H-13 was a French biplane two-engine flying boat of the 1920s, built in passenger and military variants.
The Potez 39 was a twin-seat single-engined parasol wing monoplane aerial reconnaissance and observation aircraft designed and produced by the French aircraft manufacturer Potez. It was the company's first all-metal aircraft.

The Bréguet 482 was a French four-engined heavy bomber aircraft designed just prior to the outbreak of the Second World War with two prototypes nearing completion when Germany invaded France in 1940, one of which was flown after the end of the war as an experimental platform.
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 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.
