Italian Air Force In 2007, it was reported that the
Italian Air Force intended to initially acquire a batch of 15 low rate production M-346s. On 18 June 2009, Alenia Aermacchi announced they had received an order for the first six with an option for nine more. In September 2015, the Italian Air Force started their first training course using the M-346 trainer. In March 2016, Finmeccanica signed a contract worth over 300 million Euros with the Italian Ministry of Defence for nine M-346, bringing the number of aircraft ordered by Italy to 18. In February 2018, the Italian Air Force received its 18th M-346, concluding the force's acquisition program. In 2019, four more M-346 were delivered to the newly formed Italian Air Force/Leonardo
International Flight Training School (IFTS) at
Galatina Air Base. On 12 September 2024, the Italian Air Force's aerobatic team
Frecce Tricolori unveiled the M-346 as its new aircraft to replace the
Aermacchi MB-339-A/PAN, alongside a new livery designed by
Pininfarina.
Singapore Air Force In July 2010, the M-346 was selected by the
Republic of Singapore Air Force (RSAF) to replace the
ST Aerospace A-4SU Super Skyhawks in the Advanced Jet Training (AJT) role, based at
BA 120 Cazaux Air Base in France. In a press release by the
Singaporean Ministry of Defence on 28 September 2010,
ST Aerospace was awarded the contract to acquire twelve M-346 and a ground-based training system on behalf of RSAF. As stipulated in the contract, ST Aerospace acts as the main contractor in the maintenance of the aircraft after delivery by Alenia Aermacchi while Boeing supplies the training system. The RSAF holds the distinction of being the first export customer for the type. for Italy in return for the planes. It will operate as the IAF's main training jet to replace the
McDonnell Douglas A-4H/N Skyhawk, which has served the IAF for over 40 years. On 19 July 2012, a contract was signed between Alenia Aermacchi and the Israeli Ministry of Defence to supply 30 M-346s, with the first delivery expected in the middle of 2014. The Israeli Air Force announced on 2 July 2013 that in Israeli service the M-346 would be named the
Lavi, reusing the name given to the cancelled
IAI Lavi. The IAF's first M-346 was rolled out in a ceremony at Alenia Aermacchi's factory in
Venegono Superiore on March 20, 2014.
Polish Air Force On 23 December 2013, it was announced that Poland had selected the M-346 to meet a requirement for an advanced jet trainer. A contract for eight aircraft was signed on 27 February 2014. The first two M-346s arrived at
Dęblin in November 2016. The aircraft were initially not officially accepted due to non-compliance with contract specifications. The delivery deadline was originally November 2016, but delays meant delivery and acceptance was not complete until 22 December 2017. In December 2017, Poland's
Ministry of National Defence announced it was seeking financial penalties from Leonardo of up to 100 million
zlotys (U.S. $28 million) over the delays. Additionally, the ministry had complained that the M-346 was not fully capable of simulating certain weapon systems for training purposes. On 19 November 2018, Leonardo's Aircraft Division together with Elbit Systems completed delivery of M-346 Full Mission Simulators and Flight Training Devices to the Polish Air Force. This was initially scheduled to be completed by November 2016. In March 2018, Poland signed for an additional four M-346s and support package, plus options for a further four aircraft, and a support package. In December 2018, Poland signed for the additional four aircraft, as well as upgrades to the existing fleet of eight. Deliveries and upgrade work for the total of 16 M-346 is expected to run into 2022. On 12 July 2024, a Polish Air Force M-346 Demo Team jet crashed during its flying display near Gdynia. Pilot Maj. Robert “Killer” Jeł lost his life in the crash.
Potential operators Argentina In October 2016, the
Argentine Air Force also evaluated the M-346 as a potential combat fighter to replace the
Dassault Mirage III and
Mirage 5 aircraft it had retired in 2015, as well as the
Douglas A-4AR aircraft that remain in service with only limited capability. Argentina was speculated to be interested in ten to twelve aircraft.
Austria By November 2025,
Austria finalized the purchase of twelve Leonardo M-346-FA jets, to replace the retired
Saab 105 and close a long-standing gap in its air defense and pilot training capabilities, with deployment planned in Linz-Hörsching from 2028. The package spans about €1.5 billion , including aircraft, weapons, simulators, training, and maintenance. It enables the full implementation of the
Bundesheer’s two-fleet strategy alongside the
Eurofighter, and aims to restore domestic pilot training, which was previously outsourced abroad.
Azerbaijan On 20 February 2020, the
president of Azerbaijan announced that the country would buy an undisclosed number of M-346s. The
Azerbaijani Air and Air Defence Force has a requirement to augment and replace its Soviet-era
Mikoyan MiG-29,
Sukhoi Su-25, and
Aero L-39 Albatros jets. The number of aircraft to be purchased is between 10 and 25 (10 plus an option for 15). Azerbaijani military leaders also considered the Yak-130 for the trainer requirement but selected the M-346 despite its higher price because of its lighter weight and higher maneuverability and problems with manufacturing of the engines for Yak-130. In November 2024, during the visit to Brazil by the Italian Prime Minister
Giorgia Meloni, she will meet Brazilian President
Luiz Inácio Lula da Silva to discuss the sale of 24 M-346s to the Brazilian Air Force, another six aircraft to the
Brazilian Navy and other related accords.
Colombia The M-346 FA has been pre-selected over the
KAI FA-50 Golden Eagle, but it is unclear if the purchase will be made as the Colombian Air Force is also looking to purchase an air superiority capable fighter.
Eurotraining The Advance European Pilot Training (AEPTJ) program – unofficially called
Eurotraining – a consortium of twelve European nations to give advance & lead-in fighter training with a common core course and training provided by a common aircraft – has contacted Alenia Aermacchi through the European Defence agency in 2010, for further information on the M-346. In May 2013, Alenia Aermacchi announced that the AEPTJ held a low priority for the firm and that "...progress has been slow."
Indonesia In 2010, Indonesia was considering to replace its
BAE Hawk Mk 53 trainer and
OV-10 Bronco attack aircraft with a new type, and the M-346 was among the potential candidates.
Indonesian Air Force chose the
T-50 Golden Eagle for its trainer and light attack program in May 2011. In July 2025, Indonesian Air Force delegation visited the Leonardo facility in Milan and, among other agenda, inspected the M-346FA production line. The Air Force stated that the aircraft "...serves as a reference for strengthening fighter pilot education programs and developing operational readiness". The Ministry of Defense of Indonesia stated in December 2025 that discussion regarding the M-346FA is in early stages of consideration. The Ministry of Defense signed a letter of intent for M-346F Block 20 in February 2026. One report said the deal involves the sale of 24 M-346FIs, with an option for another 12.
Ireland In July 2021, Leonardo made a submission to the Irish Commission on the Defence Forces presenting the M-346FA as a light multi-role fighter and
advanced trainer for the
Irish Air Corps. The commission has multiple tasks, including determining the future capability requirements for the
Irish Defence Forces. Currently, the Irish Air Corps has a very limited air combat capability with eight
Pilatus PC-9M training/light attack aircraft. The M-346FA could be a cheaper alternative to more expensive fighters and would be Ireland's first combat jet aircraft since the retirement of the six
Fouga CM.170 Magister aircraft in 1999. In comparison to Ireland's current air combat capability, the M-346FA would be considered by many to be a step up, introducing features such as air-to-air missiles and onboard radar.
Japan The M-346 Block 20 is speculated to be a contender to replace the aging
Kawasaki T-4. Some Japanese fighter pilots began flying the M-346 with the
International Flight Training School.
Spain Possible replacement of Spanish
Northrop F-5BMs. Although Spain signed a memorandum for cooperation in December 2024 for the
TAI Hürjet, Leonardo continues to support the sale of the M-346 to the
Spanish Air Force. In fact, a study by the University Center for Defense (CUD) in San Javier, Murcia, concluded in 2020 that this aircraft is the best option, after comparing it against other market options like the
KAI T-50 and the
Yak-130. The authors applied the Fuzzy Reference Ideal Method to rank advanced military trainer aircraft. However in 2025, it was announced that Spain had chosen to acquire the
TAI Hürjet.
Tunisia On 31 July 2025 a delegation from Leonardo, offered the M-346 as a replacement for the
Aero L-59 Super Albatros.
United Arab Emirates The M-346 was named the winner of a competition by the
United Arab Emirates at the
IDEX 2009 defense show in
Abu Dhabi on 25 February 2009. The official said the order involved delivery of 48 aircraft to be used for pilot training and light attack duties. A final request for proposals in 2010 had set the requirement at 20 trainers, 20 aircraft for combat duties, and the remainder would go toward the creation of an aerobatic team. However, by January 2010, negotiations to sign a contract had reportedly stalled over specifications. On 18 November 2011, the prototype, which had been on display at the
Dubai Airshow, crashed after departing Dubai on return to Italy.
United States Air Force Alenia Aermacchi submitted the M-346 for the
United States Air Force's
T-X program to replace the aging
Northrop T-38 Talon, rebranding it as the
Leonardo DRS T-100 Integrated Training System. Alenia originally intended to be the prime contractor, anticipating moving the final assembly location from Italy to the United States if the bid succeeded. About 350 aircraft were expected to be ordered, with further purchases leading to over 1,000 aircraft being purchased overall. In January 2013, Alenia Aermacchi signed a letter of intent with General Dynamics C4 Systems, who intended to serve as the prime contractor for the T-X bid; however, General Dynamics announced their withdrawal in March 2015. On 1 January 2016, Alenia Aermacchi was absorbed into
Leonardo S.p.A. In February 2016, it was announced that
Raytheon, which would serve as the prime contractor, had teamed up with Leonardo to offer an advanced variant of the M-346 for the T-X program called the T-100. On 25 January 2017, Raytheon announced that it had withdrawn as prime contractor and American partner in the T-X competition. One of the sticking points had been price per unit: at the time the M-346 had a flyaway cost of $25 million, but Raytheon wanted Leonardo to reduce that by 30%. On 8 February 2017, Leonardo confirmed that it would remain in the T-X competition alone, with
Leonardo DRS, its American subsidiary, serving as prime contractor. In September 2017, it was announced that the T-X program had selected the rival
Boeing T-7 Red Hawk submission instead. On the 22nd of August 2025 the
Italian Air Force and the
United States Air Force signed the “Concept of Operations (CONOPS) for Flight Training of the USAF Military Personnel in Italy” which will see U.S. student pilots, for the first time in history, be trained in a foreign NATO pilot school, the
International Flight Training School (IFTS) on the M-346. The first course with ten USAF pilots was scheduled to start on 8 September 2025, and should be completed by June 2026, leading the students to the USAF military wings.
United States Navy The M-346 is being offered to the
United States Navy Undergraduate Jet Training System (UJTS) competition to replace the aging
McDonnell Douglas T-45 Goshawk by
Leonardo (company) with
Textron Aviation Defense being the prime contractor for the bid. On 28 July 2025, Textron announced it will offer a US-made version of the Italian light jet under the designation
Beechcraft M-346N. The offer has been described to have been adapted to the Navy's revised requirements, conducting only Field Carrier Landing Practice (FCLP) approaches to wave off, thereby obviating the need for a tailhook, catapult launch bar, or extensive structural modifications for arrested carrier operations. This focus on FCLP-only training aligns with the fifth USN Request for Information (RFI) released on 31 March 2025.
Uruguay As part of the
Fuerza Aérea Uruguaya modernization efforts, Uruguay has shown interest in purchasing at least six new radar-equipped aircraft to replace its
Cessna A-37; according to sources within the force, the M-346 is favored over the
Hongdu L-15. ==Variants ==
