History Fiat Aviazione / Aeritalia
Fiat G-91Y Yankee
The Fiat (later Aeritalia) G.91Y is an Italian ground-attack and reconnaissance aircraft which first flew in 1966. Although resembling its predecessor, the Fiat G.91, the aircraft was in fact a complete redesign, a major difference being that it was equipped with a new twin-engine configuration, replacing the original single engine.
The G.91Y was an increased-performance version of the Fiat G.91 funded by the Italian government. Based on the G.91T two-seat trainer variant, the single Bristol Orpheus turbojet engine of this aircraft was replaced by two afterburning General Electric J85 turbojets which increased thrust by 60% over the single-engined variant. Structural modifications to reduce airframe weight increased performance further and an additional fuel tank occupying the space of the G.91T's rear seat provided extra range. Combat manoeuvrability was improved with the addition of automatic leading edge slats
