: "The Ariete (Ram) was the second design by Ing. Sergio Stefanutti and built by Aerfer. It differed mainly from its predesessor Sagittario (Archer) 2 by the altereations to the fuselage to adopt the 1,810 lb (821 kg) s.t. Rolls-Royce Soar R.Sr.2 turbojet in addition to the 3,600 lb (1,633 kg) s.t. Rolls-Royce Derwent 9 turbojet. The Soar engine was used to boost performance on takeoff, climb and combat, air was fed through a retractable dorsal intake. First flight of the sole aircraft was made on March 27, 1958. A planned third design, the Leone (Lion), also with mixed-power, was abondoned."
