The Alenia Aermacchi M-345 (M-311 before 2012) is a turbofan-powered military trainer aircraft. It is a development of the SIAI Marchetti S.211/Aermacchi S-211.

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 SIAI-Marchetti 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.[1]

In April 2008, Alenia and ENAER of Chile signed an agreement to jointly manufacture and sell the M-346 and M-311 in South America.[citation needed]

On 28 May 2008, Boeing and Alenia signed a joint agreement to cooperate on marketing, sales, training and product support for both the M-346 and M-311.[2][3]

On 1 June 2015, Alenia Aermacchi presented the M-345 jet to the DGA for the nascent French replacement program for its Dassault/Dornier Alpha Jets. It is developing the Williams International FJ44-4M-powered M-345 for the Italian air force.[4] The M-345 first flew on 29 December 2016.[5]

Italy placed an initial order for five M-345s for the Italian Air Force on 13 January 2017. It has a requirement for up to 50 aircraft to replace Aermacchi MB-339s used in the basic training role and by the Frecce Tricolori aerobatic team.[6]
