Dornier
G.91T
The G.91T was a two‑seat trainer version of the Fiat G.91 light attack aircraft, produced under licence by Dornier for the German Luftwaffe in the early 1960s. Development began in 1961 when the German Ministry of Defence sought a simple, low‑cost jet to replace piston‑engine trainers and to provide a bridge to frontline fighters such as the F‑104 Starfighter. Dornier received the licence from Fiat and modified the airframe to accommodate an instructor behind the student, installing dual controls, upgraded avionics and an enlarged ventral fuel tank to preserve range. Power was supplied by a Bristol Siddeley Orpheus Mk 803 turbo‑jet delivering 4,200 lb thrust, allowing the G.91T to reach 1,100 km/h and a ceiling of 13 000 m. The aircraft featured ejection seats for both crew members, a reinforced cockpit canopy, and provisions for practice weapons loads, making it suitable for weapons‑delivery training as well. Between 1962 and 1967 Dornier delivered 124 G.91Ts, which served with several Luftwaffe training squadrons for over a decade. Its robust design, ease of maintenance and economical operation cemented the G.91T’s reputation as a reliable bridge trainer, influencing later NATO jet‑trainer concepts and underscoring the value of licensed production in post‑war European aviation.
