The Ansaldo A.1, commonly known as the "Balilla" after a legendary figure from Genoa, was the sole fighter aircraft designed and manufactured within Italy during World War I. Although it arrived too late to participate significantly in the conflict, it saw operational use with both Poland and the Soviet Union during the Polish-Soviet War of 1919–1921.

Development

The creation of the A.1 stemmed from Ansaldo's ongoing pursuit to develop a contemporary fighter aircraft. The earlier SVA.5 had demonstrated inadequacies in combat roles despite excelling as a reconnaissance platform, leading to its production for that purpose. Ansaldo engineer Giuseppe Brezzi undertook modifications on the SVA.5 by reducing the upper wing's dimensions and replacing its transverse Warren truss interplane struts—which had eliminated the need for exposed flying and landing wires along the span—with traditional wire-braced struts. Although this adjustment increased aerodynamic drag, it enhanced wing rigidity, thereby improving maneuverability. Additionally, engine output was boosted to 150 kW (200 hp), and a safety feature allowing the fuel tank to be jettisoned through a ventral hatch in case of fire was incorporated.

The initial prototype was finalized in July 1917; however, official acceptance by the air force was delayed until December. Test pilots expressed reservations: despite improved performance compared to the SVA.5, the A.1 still lacked the agility of contemporary French-designed fighters operating within Italian units, particularly when compared to the Nieuport 17, which was also produced domestically by Macchi. This feedback led to several refinements, including slight enlargements of the wings and rudder, along with an additional 10% increase in engine power. These changes satisfied military requirements, resulting in the updated version, designated A.1bis, being assigned to 91 Squadriglia for further evaluation.

Pilot assessments remained varied; while speed was praised, handling difficulties and limited maneuverability persisted. Nonetheless, facing an urgent need to phase out outdated fighters, the air force proceeded with ordering the A.1.

Operational history

The first batch from an initial order of 100 units entered service in July 1918. The A.1s were predominantly allocated to homeland defense roles rather than front-line deployment. Within four months before the Armistice, Italian ace Leopoldo Eleuteri achieved the only confirmed aerial kill using an A.1—a victory over an Austrian reconnaissance plane. During this period, Ansaldo undertook promotional efforts by branding the aircraft as Balilla, conducting demonstration flights in major Italian cities, and notably gifting one example to aviator Antonio Locatelli amid media attention in August. This publicity effort suffered a setback when Locatelli was forced down behind enemy lines due to mechanical failure a week later and captured. Despite such incidents, an additional order for 100 aircraft was placed and fulfilled before war’s end. By the time of the Armistice, 186 A.1s were operational: 47 were retained for training purposes while the rest were stored.

The Ansaldo A.1 experienced a resurgence when a Polish military procurement team visited Italy in 1919 seeking new aircraft. They secured a contract for ten evaluation units, which were shipped to Warsaw in January 1920. These planes were actively employed by the Kościuszko Squadron during the Polish-Soviet War spanning 1919 to 1921. Pilots, predominantly American volunteers, praised the aircraft for its impressive speed, substantial fuel capacity, and notably for its agility—a trait undervalued by Italian aviators. The A.1s were first dispatched to combat on May 25 but nearly all were lost during a Red Army offensive in Ukraine. Despite these losses, Poland had already procured an additional 25 units and secured a license to manufacture 100 more domestically. These locally produced aircraft arrived only after the war concluded, with the first 36 license-built models emerging from the Lublin factory in July 1921.

The Lublin-produced variants weighed roughly 80 kg (180 lb) more than their Italian counterparts and suffered from persistent engine troubles and substandard weld quality. This led to a series of accidents, including at least nine fatal incidents. Consequently, the production order was cut down to 80 units in 1924, and later further reduced to 57—the quantity actually completed at that time. In 1925, all operational A.1s had their armaments removed, and by 1927, the type was fully retired from Polish service.

In Soviet service

Following the Russian Revolution, the Soviet regime honored the previous Imperial Russian government's procurement of Ansaldo aircraft from Italy, receiving a total of 30 Ansaldo A.1s between 1918 and 1920. In 1918, the newly formed 20th Military Air Fleet of Soviet Russia primarily operated foreign-made planes, including the Ansaldo A.1 powered by a SPA 6A 220 hp engine. By early 1922, the A.1 was deployed across several units: the West Military District near Kharkiv (specifically the 2nd Fighter Squadron of the 2nd Regiment), as well as naval aviation units such as the Air Forces of the Black Sea Fleet (2nd Navy Fighter Air Detachment) and the Air Forces of the Baltic Sea Fleet (1st and 2nd Fighter Air Detachments). Due to budget constraints, Soviet authorities attempted to produce their own Synchronised machineguns for these aircraft but failed to develop suitable models; as a result, the A.1s operated without armament.

Soviet pilots valued the Ansaldo A.1 for its nimbleness and straightforward handling characteristics, though engine reliability issues and other defects became apparent over time. Some aircraft were fitted with skis to facilitate operations during winter months. By 1928, these fighters had become outdated and were relegated exclusively to pilot training roles.

In Latvian service

In 1921, Latvia joined other operators by purchasing thirteen Ansaldo A.1 fighters despite a fatal accident involving Ansaldo’s test pilot during a demonstration flight in Riga. Latvian examples were distinguished by added insulation around the engine compartment to protect against cold weather conditions.

Marketing Efforts in the Americas

To establish a foothold in post-war markets, Ansaldo engaged in several promotional campaigns across North and South America. In 1919, the company dispatched six aircraft to the United States targeting private purchasers, pricing each at $6,000 USD. The aircraft's impressive velocity attracted record-seeking pilots; notably, American flying ace Eddie Rickenbacker set a national speed record in 1920 using one of these planes. Additionally, an aircraft equipped with a Curtiss D-12 engine secured third place in the 1921 US Pulitzer air race.

As part of their outreach, four aircraft toured Argentina followed by Uruguay with the aim of generating governmental interest. Ansaldo even proposed gifting two promotional units to each country along with their crews. Despite these efforts, no purchase agreements materialized. Subsequently, two aircraft were exhibited in Peru and one was presented in Honduras, but these demonstrations failed to produce orders as well. Following the unsuccessful South American marketing campaign, Ansaldo discontinued the A.1 program and was soon integrated into Fiat.

In 1920, Mexico procured a single unit which served within the Fuerza Aérea Mexicana for several years.
