Ansaldo SVA A1
Ansaldo achieved aeronautical eminence in 1917 by providing a single-seat fighter of original Italian design (Italy having previously used French types). The aircraft was the A-1 Balilla ("Hunter"). About 150 built; others, license-built in Poland, served well into 1920s.
The Ansaldo A 1 Balilla was a basic biplane fighter design with a four-blade propeller and a 220 horsepower SPA 6A water-cooled in-line engine. A single pilot saw behind the biplane wing. Armament consisted of two 7.62mm British Vickers machine guns mounted forward of the cockpit seating area in a forward-firing fixed position. Endurance amounted to 1 hour and 30 minutes.
The A 1 appeared in the final stages of the First World War, limiting its use to post-war defence of Italy. Some models found their way into American hands and were converted to air racers fitted with a Curtiss powerplant. Still others would see combat at the hands of Russian and Polish flyers in the Russo-Polish war in 1920.
