The Savoia-Marchetti S.57 was an Italian single-engine biplane flying boat intended for aerial reconnaissance, built by Savoia-Marchetti for Regia Aeronautica after World War I.
Of wooden construction with a single-step hull, with pilot and observer/gunner in tandem open cockpits in the bow, the S.57 was powered by a single 186 kW (249 hp) Isotta-Fraschini V.6. The observer had a single ring-mounted 7.7 mm (0.303 in) machine gun.
Eighteen S.57s were accepted by Regia Aeronautica in 1925 and used as trainers.
A sole S.57bis (improved) was built, with a 224 kW (300 hp) Hispano-Suiza Type 42 engine.

The Savoia-Marchetti S.55 was a double-hulled flying boat produced in Italy, beginning in 1924. Shortly after its introduction, it began setting records for speed, payload, altitude and range.
The Savoia-Marchetti SM.81 Pipistrello was the first three-engine bomber/transport aircraft serving in the Italian Regia Aeronautica. When it appeared in 1935, it represented a real step ahead in Italian military aviation: it was fast, well armed and had a long range. It proved effective during the war with Ethiopia and the Spanish Civil War. Despite being too slow to remain competitive as a bomber in the later years of World War II, it was one of the most flexible, reliable and important aircraft of the Regia Aeronautica from 1935 to 1944, and adapted to second-line duties in a wide range of tasks.
The CANT Z.1007 Alcione (Kingfisher) was an Italian three-engined medium bomber, with wooden structure. Designed by Filippo Zappata, who also designed the CANT Z.506 it had "excellent flying characteristics and good stability" and 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 CANT Z.501 Gabbiano was a high-wing central-hull flying boat, with two outboard floats. It was powered by a single engine installed in the middle of the main-plane and had a crew of 4–5 men. It served with the Italian Regia Aeronautica during World War II, as a reconnaissance aeroplane. During its debut in 1934, it set a world distance record. It was obsolete by 1940, but was still used throughout World War II, suffering many losses. A few remained in service until 1949.
The Fiat CR.1 was an Italian biplane fighter aircraft of the 1920s. Of wood-and-fabric construction, it was designed by Celestino Rosatelli, from whom it gained the 'CR' designation. Its most distinctive feature was that the lower wings were longer than the upper ones.
The Savoia-Marchetti SM.85 was an Italian monoplane dive bomber and ground-attack aircraft that served in small numbers in the Regia Aeronautica at the beginning of World War II. They were soon replaced in service by the Junkers Ju 87.

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.
