Design and development
The M-345 is a small tandem two-seat shoulder-wing monoplane with a retractable tricycle landing gear, powered by a single Pratt & Whitney Canada JT15D-5C turbofan. It is based on the earlier S-211, with the addition of both structural and equipment improvements. The airframe has been strengthened, and a glass cockpit and modern avionics have been added. As a basic trainer, the aircraft is designed to complement the Aermacchi M-346 advanced trainer. The aircraft was designed with a secondary close air support capability with five underwing hardpoints.
The prototype aircraft first flew in June 2005.
On 1 June 2015, Alenia Aermacchi presented the M-345 jet to the DGA for the nascent French Dassault/Dornier Alpha Jet replacement program. It is developing the Williams International FJ44-4M-powered M-345 for the Italian air force. The M-345 first flew on 29 December 2016.
