The Ambrosini Sagittario was an Italian aerodynamic research aircraft based on the manufacturer's S.7. New swept wings and tail surfaces of wooden construction were fitted to the S.7 fuselage. The wing leading edge was swept at 45 degrees. At first, the S.7's piston engine was retained and the aircraft was known as the Ambrosini S.7 Freccia (Arrow).

Sagittario
Role	Research aircraft
Manufacturer	Ambrosini
First flight	5 January 1953
Number built	1
Developed from	Ambrosini S.7
Developed into	Aerfer Sagittario 2

After several test flights in this configuration (the first on 5 January 1953), the piston engine was removed and replaced with a Turbomeca Marboré turbojet of 3.7 kN (840 lbf) thrust, and the aircraft renamed the Sagittario. The engine air inlet was in the extreme nose, and the exhaust was routed out the bottom of the fuselage, under the cockpit. The tail wheel undercarriage was retained, so special shielding was added to protect the tail wheel from the engine exhaust.

The later Aerfer Sagittario 2 differed in having a tricycle undercarriage and fully transparent cockpit glazing.

Die Ambrosini Sagittario war ein durch Strahltriebwerke angetriebener Abfangjäger des italienischen Flugzeugherstellers SAI-Ambrosini. Sie wurde auf der Basis der Ambrosini Super S.7, eines kolbenmotorgetriebenen Schulflugzeuges, bei Ambrosini Anfang der 1950er Jahre entwickelt. Als Antrieb war zunächst die französische Leichtturbine Turboméca Marboré II vorgesehen. Die als Sagittario bezeichnete Maschine erhielt als erste italienische Konstruktion um 45° gepfeilte Tragflächen.
