The Leonardo M-345 series of light strike and advanced trainer aircraft is in-development to replace the outgoing MB339 series.


Detailing the development and operational history of the Leonardo (Alenia Aermacchi) M-345 Advanced Jet Trainer / Light Attack Aircraft.  Entry last updated on 2/21/2018. Authored by Staff Writer. Content ©www.MilitaryFactory.com

The Leonardo M-345 currently exists as an in-development, advanced two-seat jet trainer of Italian origin. The aircraft is an evolved form of the earlier SIAI-Marchetti S.211 / S-211 and was developed from the subsequent M-311 series. A program first-flight was recorded in June of 2005 while the M-345 prototype went airborne for the first time on December 29th, 2016 (at the Venegono Superiore company facility). At least two prototypes have been built as of 2017. Beyond its given advanced jet trainer role, the design is being completed with a secondary light attack function.

The M-345 directly succeeds the Aermacchi MB-339 jet trainer of 1979, itself a development of the MB-326 of 1962.

NOTE: The SIAI-Marchetti brand label was absorbed into Aermacchi in 1997 to which then Aermacchi became Alenia Aermacchi in 2012. The product now exists under the Leonardo S.p.A. (formerly Leonardo-Finmeccanica / Finmeccanica) brand label.

The M-345 utilizes a conventional trainer aircraft design philosophy where the student and trainer are seated under a single-piece, lightly framed tandem-seat cockpit aft of a short nosecone. A single powerplant is used to help the airframe achieve its required high-performance specifications. The wing mainplanes are shoulder-mounted and feature boundary layer fences for added control. The empennage is dominated by a single vertical fin set over the engine exhaust port. Horizontal planes are featured at the base of the fin. The undercarriage is of a tricycle configuration and wholly retractable. Empty weight is 2,300 kilograms against an MTOW of 4,100 kilograms. Physical specifications include a length of 9.85 meters, a wingspan of 8.47 meters and a height of 12.6 meters.

Power is from a single Pratt & Whitney JT15D-5C series turbofan engine outputting 3,190 lb of thrust. Performance specifications include a maximum speed of 740 kmh with a range out to 1,780 kilometers and a service ceiling up to 12,190 meters. Rate-of-climb is 1,440 meters per minute.

Five hardpoints are available for carrying ordnance loads up to 2,205lb (for either training or combat sorties). Options typically include gun pods, cannon pods, rocket pods and conventional drop bombs.

The aircraft, in its original form, was the M-311 and this was the updated version of the original S.211. Two prototypes were built to prove the design sound. It was redesignated in 2012 to become the M-345. One other version of note is the M-345 HET, a High-Efficiency Trainer, powered by a Williams International FJ44-4M turbofan engine.

The M-345 is under consideration for the USAF's T-X advanced trainer competition as well as for the Italian Air Force's new trainer requirement. The French Air Force is considering the Italian design to replace its aging fleet of Dassault-Dornier Alpha Jets.

Another possible operator includes Chile who joined Alenia (through ENAER) in April of 2008 to jointly-produce the M-345 for South American customers. A May 2008 deal saw defense industry giant Boeing join forces with Alenia to market, sell and support the M-45 product.
