Indonesia Secures Revised Role In KF-21 Fighter Programme, Preserving Industrial Access While Reducing Financial Burden

At IndoDefense 2025, South Korea and Indonesia signed a revised agreement that resets Jakarta’s financial commitment to the KF-21 Boramae fighter jet programme, ensuring continued Indonesian participation while alleviating long-standing budgetary strain. The new terms reduce Indonesia’s contribution from 1.6 trillion won ($1.17 billion) to 600 billion won ($438 million), and include an updated payment schedule and permission for partial compensation through commodities such as palm oil and coffee. Despite the financial adjustment, Indonesia retains its industrial role through PT Dirgantara Indonesia (PTDI), which will continue manufacturing components and supporting future operations for the 48 aircraft allocated under the programme.

The agreement, reached during a trilateral meeting in Jakarta between South Korean Defence Minister Shin Won-sik, Indonesian Defence Minister Prabowo Subianto, and Hanwha Aerospace CEO Son Jae-il, ends a prolonged impasse over unpaid contributions and secures the only foreign partnership in South Korea’s flagship aerospace project. First initiated through a 2010 memorandum of understanding and formally launched in 2015, the KF-21 programme originally allocated 60% of the funding to the South Korean government, 20% to KAI, and 20% to Indonesia. However, Indonesia began falling behind on payments in 2019, contributing only 278.3 billion won by late 2023—less than half of its commitment—prompting public pressure from Seoul and the threat of ejection from the programme.

Strategically, the revised deal reflects a pragmatic recalibration of industrial partnership dynamics in an era of fiscal constraints and geopolitical diversification. For Indonesia, the ability to maintain access to advanced 4.5-generation fighter capabilities without full financial exposure is a significant achievement. With multiple procurement pathways under review—including deals for Rafale F4, F-15EX, TAI KAAN, and possibly Chinese J-10C aircraft—Jakarta is positioning itself as a neutral but diversified aerospace customer.
