Concerning the abandon of the Aerfer fighter projects, rumours are of lobby activity by U.S.A. (for the F-86 Sabre) and by FIAT (for its G 91).

Very interesting plane. It had Hispano-Suiza HS-825 cannons which have scarce info on but I gathered enough. Shell size: 30mm Shell length: 113mm Cannon weight: 360 kg Rate of fire:1,350 per minute Muzzle velocity: 1,050 m/s The Ariete had 240 rounds in total in those 30mms.
