这 菲亚特G.46 was a military trainer developed in Italy shortly after World War II. The G.46 was a conventional, low-wing monoplane with tailwheel undercarriage, the main units of which retracted inwards. The pilot and instructor sat in tandem under a long canopy. The first prototype, powered by a 205 hp (153 kW) Alfa Romeo 115-Ibis engine, made its maiden flight on 25 June 1947.

General Characteristics
The Fiat CR.46 was a 1930s Italian single-seat fighter biplane designed by Celestino Rosatelli for Fiat, intended to compete for the Regia Aeronautica’s (Italian Air Force) requirement for a new generation of fighters. It was developed shortly after the successful CR.42 Falco and was designed to explore a lighter, higher-performance path. The aircraft featured the classic robust all-metal construction typical of Rosatelli’s designs, but with a more streamlined fuselage than its predecessors. Although the CR.46 demonstrated strong performance and was fast, its design was ultimately sidelined as Italy transitioned toward monoplane fighters (like the Macchi C.200) and focused its biplane production on the already established CR.42. Only one prototype was ever built.

Powerplant and Performance
- Engine: 1 x Fiat A.74 RC.38 14-cylinder air-cooled radial piston engine.
- Power Output: 649 kW (870 hp) at 3,800 m (12,470 ft).
- Maximum Speed: 480 km/h (298 mph) (projected).
- Service Ceiling: 10,200 m (33,460 ft).
- Climb Rate: Could reach 6,000 m (19,685 ft) in 5 minutes 30 seconds.
- Key Feature: Used a semi-retractable landing gear system, with the main wheels partially folding back into the undercarriage fairings (spats) to reduce drag while maintaining the simplicity of fixed gear.
Armament and Fate
- Fixed Armament: Typically planned for 2 x 12.7 mm (.50 in) Breda-SAFAT machine guns mounted above the engine cowling, synchronized to fire through the propeller arc.
- Operational Fate: The CR.46 prototype was completed and tested successfully. However, the Regia Aeronautica was already committed to ordering the CR.42 and was quickly shifting its priorities toward monoplane fighters (like the Fiat G.50 and Macchi C.200) which offered higher top speeds.
- Legacy: Although the CR.46 was never mass-produced, its design and high-speed features (like the streamlined engine cowling and partially retractable gear) served as a stepping stone in Italian fighter design before the transition to fully modern monoplanes.
