[SM-91] - In 1942, the Regia Aeronautica requested designs for a new aircraft, propelled by the DB605 engine, capable of flying at (385 mph) with a range of (990 mi). The armament should consist of six MG 151 cannons in the nose and wings and a 12.7 mm machine gun as a defensive weapon. It should have an 800 kg (1,800 lb) bomb load. At that point, the request for a long-range fighter killed the SM.88, still in development, and the SM.91, A mutch more modern design, was authorized.
Fiat G.50 Freccia ("Arrow") First flown in February 1937, the G.50 was Italy’s first single-seat, all-metal monoplane with an enclosed cockpit and retractable undercarriage to go into production. In early 1938, the Freccias served in the Regia Aeronautica (the Italian Air Force), and with its expeditionary arm, the Aviazione Legionaria, in Spain, where they proved to be fast and, as with most Italian designs, very maneuverable. Armed with two powerful Breda-SAFAT 12.7mm machine guns.
