Macchi M.C.77

The Breda Ba.88 Lince ("Lynx") was a ground-attack aircraft used by the Italian Regia Aeronautica during World War II. Its streamlined design and retractable undercarriage were advanced for the time, and after its debut in 1937 the aircraft established several world speed records. However, when military equipment was installed on production examples, problems of instability developed and the aeroplane's general performance deteriorated. Eventually its operational career was cut short, and the remaining Ba.88 airframes were used as fixed installations on airfields to mislead enemy reconnaissance. It represented, perhaps, the most remarkable failure of any operational aircraft to see service in World War II.

The CANT Z.1007 Alcione (Kingfisher) was an Italian three-engined medium bomber, with wooden structure. It was designed by Filippo Zappata, who also designed the CANT Z.506 and had "excellent flying characteristics and good stability". It was regarded by some as "the best Italian bomber of World War II" although its wooden structure was easily damaged by the climate, as experienced in North Africa and in Russia. It was used by the Italian Regia Aeronautica, Italian Co-Belligerent Air Force, Aeronautica Nazionale Repubblicana and Luftwaffe during World War II.

The AUT.18 was a prototype fighter aircraft developed in Italy by Aeronautica Umbra shortly before the outbreak of World War II. It was designed in 1934 by Felice Trojani, who at that time was collaborating with Umberto Nobile on the Arctic flights of the airships Norge and Italia. The aircraft's designation came from initials of the manufacturer, the surname of the designer, and the aircraft's wing area, the sole prototype receiving the serial no. M.M.363.

The Breda Ba.64 was an Italian single-engine ground-attack aircraft used by the Regia Aeronautica during the 1930s.

The CRDA CANT Z.1018 Leone (Lion) was an Italian medium bomber of the 1940s.

The Savoia-Marchetti SM.91 was a two-seat, twin-engined, Italian heavy fighter prototype, designed to compete in a 1942 revision to a long-range fighter-bomber contract offered by the Regia Aeronautica to Italian aircraft companies in 1938. The original 1938 specification yielded the Savoia-Marchetti SM.88, which the SM.91 was largely based on.

The Breda Ba.201 was an Italian dive bomber designed during World War II, that never entered production.

The Caproni Vizzola F.5 was an Italian fighter aircraft that was built by Caproni. It was a single-seat, low-wing cantilever monoplane with retractable landing gear.

The Piaggio P.119 was an Italian experimental fighter of World War II. It had a relatively novel layout, with a "buried" radial engine mounted mid-fuselage. Only a single prototype was built before the Armistice between Italy and the allied armed forces, which ended the project.

The IMAM Ro.51 was an Italian fighter aircraft that first flew in 1937. It was designed for the 1936 new fighter contest for the Regia Aeronautica, with practically all the Italian aircraft builders involved.

The IMAM Ro.57 was an Italian twin-engined, single-seat monoplane fighter of the Regia Aeronautica. Based on a 1939 design by Giovanni Galasso the aircraft did not enter production until 1943.

The Caproni Ca.132 was a prototype for a large aircraft built in Italy in 1934, intended for use as either a bomber or airliner. It was a conventional low-wing cantilever monoplane, powered by a radial engine on each wing and in the nose. The main undercarriage was housed within large streamlined spats. Configured as an airliner, it would have seated 20 passengers.

The Caproni Ca.311 was a light bomber-reconnaissance aircraft produced in Italy prior to and during World War II.

The Caproni Ca.355 Tuffo was a low-wing single-engine dive bomber, designed and built by the Italian Caproni company in 1941, which never proceeded beyond a single prototype. Derived from Ca.335 Mistral, the Ca.355 was proposed to equip the Regia Aeronautica, but it was found to offer little advantage over the German Junkers Ju 87 "Stuka" and the project was abandoned.

The Caproni CH.1 was a single-seat biplane fighter, a single example of which was produced as a prototype in Italy in 1935.

The Caproni Vizzola F.4 was an Italian fighter aircraft prototype that was designed in 1937 and built from 1939. It was a single-seat, low-wing cantilever monoplane with retractable landing gear.

The Caproni Vizzola F.6 was a World War II-era Italian fighter aircraft built by Caproni. It was a single-seat, low-wing cantilever monoplane with retractable landing gear. Only two prototypes were built, one designated F.6M and the other designated F.6Z.

The Breda Ba.82 was an Italian medium bomber prototype of the late 1930s; it was designed and built by the Breda company.
