The Fiat CR42 Falco, was the Regia Aeronautica's last biplane fighter in a period when the monoplane had already gained predominance, yet was the combat aircraft built in the greatest number by the Italians during World War II. 1,781 of these agile and robust aircraft came off the production lines - despite the presence of (and the need for) more modern and competitive planes. It was also a successful export, seeing service in the liveries of Belgium, Hungary and Sweden.
