Indonesia’s M-346 Localisation Test
Will twelve Block 20 aircraft create sovereign training and support capacity—or another OEM-dependent fleet?
On 21 July 2026 Leonardo and PT ESystem Solutions Indonesia announced the signing of a contract to supply the Ministry of Defence of the Republic of Indonesia with twelve M-346 F Block 20 multirole light fighter aircraft, with deliveries expected to start in 2030 and with the localisation of a range of support, maintenance, overhaul and training capabilities as well as human capital development. Twelve aircraft is a small fleet, and the transaction is strategically larger than that number. It sits against two magnitudes drawn from Indonesian instruments. The first is statutory: Article 43 of Law No. 16 of 2012 requires foreign procurement of defence and security equipment to carry countertrade, local content and/or offset of at least 85 per cent of contract value, of which local content and/or offset must be at least 35 per cent, a floor the act states as rising by 10 per cent every five years. The second is budgetary: the Ministry of Defence’s priority-programme note for 2025 allocates Rp52.103 trillion to the modernisation of defence equipment, non-equipment and defence infrastructure, against Rp1.531 trillion to defence research, industry and higher defence education. The structural constraint sits in the distance between those two figures: a legal regime demands industrial return on a scale the domestic industrial and research programme is not funded to absorb. What the contract does not publicly establish is a transfer of design authority, software control, independent weapon-integration rights or autonomous supply-chain authority. The central question is therefore not whether localisation exists, but what kind.
The report proceeds in four sections. The first reconstructs the strategic and institutional architecture, working from Leonardo’s February 2026 letter of intent and its July 2026 contract announcement, the Indonesian Air Force’s account of its Chief of Staff’s July 2025 visit to Leonardo’s Milan facilities, Leonardo’s 2025–2029 industrial plan and its July 2024 M-346 capability enhancement note, and identifying the Ministry of Defence, the Indonesian Air Force, Leonardo, PT ESystem Solutions Indonesia and the Defence Industry Policy Committee as the parties to that architecture. The second works the legal and budgetary mechanics through Law No. 16 of 2012, Government Regulation No. 76 of 2014 and its explanatory memorandum, the Ministry of Defence’s 2025 priority-programme note and its July 2025 budget statement to Commission I of the House of Representatives, and the Italian Ministry of Foreign Affairs’ description of the authorisation sequence under Law No. 185 of 1990. The third examines industrial and technological content through the Block 20 enhancement note, the M-346 product page and the M-346FA brochure, the July 2026 Leonardo–CAE collaboration agreement, the Indonesian record of the 2023 IDEX and NAVDEX agreements, and Leonardo’s 2023 long-term support contract with WZL1 for the Polish M-346 fleet. The fourth sets out the decision-relevant implications. The report does not value the contract, does not reconstruct workshare, and does not assert what the undisclosed contractual annexes contain.
