Lla Aerfer Sagittario 2 (sagittaire en italien) était un prototype d’avion de chasse léger monoplace entièrement métallique construit en Italie par Aerfer, destiné à servir d’intercepteur ou d’avion léger de soutien tactique. Piloté pour la première fois en 1956, il est devenu le premier avion italien à franchir le mur du son en vol contrôlé lorsqu’il a atteint Mach 1,1 lors d’une plongée de 13 725 m (45 000 pi).

General Characteristics
The Aerfer Sagittario 2 (Italian for « Sagittarius » Ou « Archer ») was an Italian prototype single-seat lightweight jet fighter developed in the mid-1950s. It is historically significant as the first Italian aircraft to break the sound barrier in a controlled flight, achieving Mach 1.1 in a dive on December 4, 1956. Developed from the piston-engined Ambrosini S.7 trainer, the Sagittario 2 was an all-metal design intended to compete for the NATO standard lightweight fighter contract, which was ultimately won by the Fiat G.91.

Design and Powerplant
- Engine: One Rolls-Royce Derwent 9 centrifugal-flow turbojet.
- Thrust: 16 kN (3,600 lbf).
- Configuration: Low-wing, all-metal monoplane with a tricycle undercarriage. It featured highly swept wings and tail surfaces typical of early jet age designs.
- Engine Placement: The jet engine was mounted in the nose of the fuselage, with the air intake at the front and the exhaust exiting beneath the mid-fuselage. This ventral exhaust configuration was a key distinguishing feature.
- Cockpit: Equipped with a bubble canopy providing excellent visibility.
Performance and Armament
- Maximum Speed (Level Flight): Approximately 1,005–1,050 km/h (625–652 mph, 543–567 knots) at sea level.
- Mach Achievement: Reached Mach 1.1 in a controlled dive.
- Service Ceiling: 12,000 m – 14,000 m (39,000 ft – 46,000 ft).
- Rate of Climb: Approximately 42 m/s (8,300 ft/min).
- Range: 765 km (475 mi, 413 nmi).
- Fixed Armament: Two 30 mm (1.181 in) Hispano-Suiza HSS 825 L/70 cannon (nose-mounted, 300 rounds per gun capacity).
- Hardpoints: Two underwing hardpoints for external stores, with a capacity of 318 kg (701 lb), which could carry:
- Bombs: 2 x 227 kg (500 lb) bombs.
- Rockets: 12 x 7.62 cm (3 in) rockets.
- Successor: The Sagittario 2 served as the basis for the more advanced, but still experimental, Aerfer Ariete, which added a Rolls-Royce Soar auxiliary jet engine for enhanced climb performance.
