Fiat Aviazione

G.91Y

The Fiat G.91Y, developed by Fiat Aviazione in the early 1970s, was an evolution of the successful G.91 light attack and trainer that had served the Italian Air Force since the 1950s. Seeking higher performance and greater versatility, Fiat introduced a twin‑engine configuration, a larger wing and a reinforced airframe, allowing the Y variant to carry a broader payload and operate from shorter, unprepared runways. Powered by two afterburning Turbomeca Aubisque engines, the aircraft could reach speeds of Mach 0.9 and climb to 12 000 m, while retaining excellent maneuverability at low altitude. Avionics were upgraded with a modern HUD, navigation radar and a digital fire‑control system, enabling both close‑air support and reconnaissance missions. Between 1975 and 1982, the Italian Air Force acquired 56 G.91Y aircraft, which later saw service with the Argentine Navy and several NATO training units. Though never exported in large numbers, the G.91Y demonstrated the effectiveness of a low‑cost, multirole platform and influenced later European light attack designs, cementing Fiat Aviazione’s reputation as a capable military‑aeronautics manufacturer. Its operational record proved reliable in harsh environments, reinforcing its reputation as a durable and adaptable workhorse.
