A nickname taken from Genoese folklore

"Balilla" is the nickname by which the Ansaldo A.1 became known, taken from a popular hero of Genoa. The aircraft was the only Italian-designed fighter of the First World War that came to be produced in Italy.

A slow debut and lukewarm trials

The first prototype was finished in July 1917, but the Corpo Aeronautico Militare didn't accept it until December that year. That reluctance stemmed from test pilots not being enthusiastic during the evaluation. They found the A.1 to be a noticeable performance improvement over the SVA.5, but the fighter remained less agile than the French-designed and -built types in use with Italian squadrons, in particular the Nieuport 17, which Macchi also produced in Italy. Against the French fighters of those years, agility remained the type's weak point, even though it was better than the SVA.5.

Production and a second life in Poland

Ansaldo built around 250 examples and Lublin another 57 under license. A contract was signed for ten evaluation aircraft, delivered to Warsaw in January 1920. There they saw intensive use with the Kościuszko squadron during the Polish-Soviet War.
