The Aerfer Sagittario 2 (Italian for sagittarius) was a prototype all-metal single-seat lightweight fighter aircraft built in Italy by Aerfer, intended to serve as an interceptor or light tactical support aircraft.

First flown in 1956, it became the first Italian aircraft to break the sound barrier in controlled flight when it reached Mach 1.1 during a dive from 13,725 m (45,000 ft).

A small all-metal aircraft, the Sagittario 2 had its jet engine mounted in the nose, with the exhaust underneath the mid-fuselage.

The cockpit was moved forward of its position on the Sagittario's predecessors, and equipped with a bubble canopy.
