Italy’s M-345 Fighter Trainer Slated for Contract This Year

ROME — The M-345 HET, the latest jet trainer to be developed by Italy’s Leonardo-Finmeccanica, will be acquired by the Italian Air Force this year once the Italian government releases initial development funding, a senior defense source has told Defense News.

The new aircraft, which will prepare pilots to move up to the firm’s advanced M-346 trainer, is edging towards first flights this year and may enter service by the end of 2018, company officials said.

Three years after the company announced it would develop the M-345 to replace its MB-339 trainer, Leonardo-Finmeccanica will be showing off the cockpit of the new aircraft at Farnborough, with officials calling the aircraft “unbeatable” for life cycle cost.

The M-345 basic-advanced trainer is based on the firm’s planned, but never-produced, M-311 trainer, albeit with new engines, avionics and some structural aerodynamic changes.

The M-311 was in turn a development of the S-211, which was sold to the Philippines, Singapore and Haiti.

The M-345 prototype now being readied is based on the M-311. It will have the M-345’s selected engine — the Williams FJ44-4M-34 — installed, and fly this year, officials said.

That will be followed by the flight by end 2017 of a pre-series aircraft which will feature the cockpit, complete with three multi-function screens and a Head Up Display for the pilot as well as three multi-function screens and a repeater of the HUD for the back seat.

The three-screen cockpit is similar to the M-346, even if Leonardo-Finmeccanica has decided that the version of the M-346 it will offer to the US in the TX bid will have just one large screen, in keeping with the F-35 configuration.

“We will keep a ‘classic’ cockpit with three multi-function screens on the M-345 because as a Phase II and III trainer, students could be selected to fly helicopters or multi-engine transports,” said an official. “Furthermore, most of the 4th/5th-generation fighters today, and at least up to 2030, still feature a 3-MFD cockpit configuration.”

The flight schedule, followed by deliveries in 2018, marks a slippage from earlier announcements of pre-series flights in 2016 and deliveries in 2017.

What could help accelerate the program is the €9 million in development funding that appeared in this year’s Italian defense budget, the first money slated for the M-345 program. “A contract is likely to be signed this year,” a senior defense source said.

The Williams engine is seen by Leonardo-Finmeccanica as a key selling point for the new aircraft, offering 3,400 lbs of thrust, ten percent more than the M-311.

Leonardo-Finmeccanica Aircraft Division officials have credited the engine with boosting the low life cycle cost of the new plane, which it says will be similar to or lower than that of a turbo-prop aircraft.

Thanks to its civil applications, the engine’s parts are more widespread and cheaper than a military engine, lowering maintenance costs, they said.

After signing a letter of intent with the Italian Air Force to jointly develop the aircraft three years ago, Air Force pilots will undertake flight testing, as they did with the M-346, as well as contributing to developing the avionics and ergonomics.

The next step will be developing an armed version with four hardpoints — two on each wing. With 4,500kg maximum takeoff weight, the plane has a spare 1,200kg for armaments.

As with the M-346, Leonardo-Finmeccanica is trying to create an integrated training system, where the aircraft is just one of several components.

For the Italian Air Force, the firm envisages a desktop training system, a 220-degree simulator and a mission-planning and briefing system. “We don’t plan a full mission simulator because in Phase II training students focus on navigation, instruments and general handling,” said the official. “But we are ready to do a full mission simulator if the client requests it, especially if the M-345 will be used for tactical training,” he added.

After contracting CAE to provide simulators for the M-346, the official said Leonardo-Finmeccanica might build simulators in-house for the M-345. “We are leaning to ‘make’ rather than ‘buy,’ since we have developed the capabilities,” he said.

The M-345 is a basic-advanced, lightweight trainer jet developed by Alenia Aermacchi for the basic-advanced stage of pilot training. The new aircraft will meet various training requirements of the armed forces across the world.

Based on developments on the M-311 demonstrator, the M-345 trainer is cost-effective, and offers low acquisition and life-cycle costs in comparison to heavyweight turboprop trainers.

Design features and technical details of M-345 trainer jet


The M-345 is a light, tandem twin-seat shoulder wing aircraft. The strengthened airframe offers fatigue life of 15,000 flight hours. It integrates a retractable tricycle landing gear and a single turbofan engine.

Improved features of the M-345 include integrated pressure re-fueling and a two-level maintenance concept which minimises operating costs. Together with the trainer jet’s On-Board Oxygen Generating System (OBOGS) operators can reduce the manpower required for ground maintenance, and cut down on turnaround times to conduct more sorties per day.

The M-345 has an overall length of 9.85m, wingspan of 8.47m, and height of 3.74m. The wing area of the aircraft is 12.6m2. The aircraft has an empty weight of 3,300kg and a maximum take-off weight of 4,500kg. The external load carrying capability makes the M-345 suitable for secondary missions.

M-345 cockpit and avionics


The advanced glass cockpit of the M-345 can accommodate two crew members in tandem configuration. The fully digital glass-cockpit is equipped with Hands On Throttle-And-Stick (HOTAS) controls and three 5in x 7in LCD multi-function displays (MFDs) for instructor and student pilot. The forward cockpit is fitted with a Head Up Display (HUD), while the rear cockpit is installed with a HUD repeater.


Cockpit features include Night Vision Goggles (NVGs) compatibility along with an integrated Global Positioning System (GPS) or Inertial Navigation System (INS), digital moving map, and two mission computers.

The trainer jet is also equipped with an embedded tactical simulation suite that was successfully integrated on the MB-339 and M-346 advanced trainers produced by Alenia Aermacchi. The aircraft integrates a Stores Management System (SMS) too.

Similarities between the M-345 and M-346 cockpits and the respective training syllabuses will also ensure interoperability during joint training operations.

It’s Bigger, It’s Better

Williams International sets a new standard in value with the introduction of the FJ44-4 turbofan engine. The 3600-pound class “Dash Four” offers more power, lower acquisition and operating cost, and same great reliability.

Using essentially the same proven core with a continued infusion of improved technology, this new dual-channel FADEC-equipped turbofan engine will provide significantly better value than existing engines in its target thrust class.

Engine Characteristics
Thrust Class…..3600 lbf
Length……………52.8 in
Diameter………..25.3 in
Weight (dry)……650 lb

The M-345 is powered by a turbofan engine developing a maximum thrust of 1,600kg (3,500lb) at take-off. The fuel is supplied by an internal tank with a storage capacity of 700kg. The Health and Usage Monitoring System (HUMS) aboard the aircraft provides information on the structure, engine and other systems to monitor the operational status of each single component/system.

Performance of the M-345 trainer aircraft

The M-345 trainer can fly at a cruise speed of 420KTAS. The certified service ceiling of the aircraft is 40,000ft.

The aircraft has a rate of climb of 5,400ft/min. It can reach a distance of 840nm, but the ferry range can be extended to 1,100nm by integrating two external tanks (10% reserve).

The aircraft has a limit load factors of +7/-3.5g at 3,300kg take-off weight. The lengths of ground run required for take-off and landing of the aircraft are 460m and 450m respectively.
