It also served as a light bomber, transport, fighter and reconnaissance aircraft, and finally as an advanced trainer, with examples in service as late as 1940.

50 examples were also license-built in Poland at ZM E. Plage & T. Laśkiewicz, but were not a success due to poor quality.

Based on Ansaldo's highly successful World War I Balilla and S.V.A scouts, the A.300 was a conventional single-engined two-bay open cockpit biplane of mixed metal and wood-and-fabric construction, powered usually by a water-cooled Fiat A.12bis V12 engine.

This became the standard multi-role aircraft in the newly formed Regia Aeronautica and served in Italy, Sicily, Sardinia, Corfu, Libya and Eritrea.

Despite this, and possibly because it was Italian rather than French or British, it remains one of the least documented contemporary types, certainly the most obscure produced in anything like these numbers.
