Bilateral defence relations between Indonesia and the United States (US) have seen significant development in recent years. The relationship reached a high point in April 2026, when the two nations officially elevated their defence ties to a Major Defence Cooperation Partnership (MDCP).
This strategic move marks a new chapter in the enhancement of defence diplomacy between Indonesia and the U.S., building upon a partnership established over several decades. The following are key trends and recent developments regarding defence cooperation between the two nations:
First, the signing of the Major Defence Cooperation Partnership (MDCP) declaration. Indonesian Defence Minister Sjafrie Sjamsoeddin and U.S. Secretary of Defence Pete Hegseth met at the Pentagon in Washington, D.C., to formalize the new MDCP partnership.
This framework aims to strengthen interoperability, the modernization of major defence equipment, and operational coordination within the region. The cooperation rests on three main pillars: military modernization, professional military education and training, and the expansion of joint exercises.
Second, the conduct of the Super Garuda Shield 2026 joint exercise. The multinational Super Garuda Shield 2026 exercise was officially inaugurated in Bandung, West Java, involving thousands of personnel from Indonesia, the United States, and over a dozen other partner nations.
The scope of this year's exercise has been expanded to include airborne operations, cyber exercises to support Indonesian National Armed Forces (Tentara Nasional Indonesia/TNI) cyber units, maritime operations, and natural disaster response (Humanitarian Assistance and Disaster Relief/HADR).
Third, enhancing cooperation on humanitarian matters and sovereignty issues. In addition to military exercises, the Indonesian Ministry of Defence and US counterparts signed a Memorandum of Understanding (MoU) regarding the search for and repatriation of the remains of soldiers who perished during World War II in Indonesia.
The Indonesian government continues to emphasize that all such enhanced cooperation proceeds in accordance with the principles of an independent and active foreign policy and full respect for national sovereignty.
Formalizing the Major Defence Cooperation Partnership
The elevation of the relationship to an MDCP was formalized during a meeting between Indonesian Defence Minister Sjafrie Sjamsoeddin and U.S. Secretary of Defence Pete Hegseth at the Pentagon on April 13, 2026. This partnership rests on three key pillars grounded in the principles of national sovereignty and mutual respect: military modernization and capacity building, professional military training and education, and operational exercises and cooperation.
The US government has welcomed this partnership with Indonesia, noting the active and ongoing development of the security relationship between the two nations. The partnership reflects the strength and potential of the US-Indonesia security relationship while bolstering regional deterrence. It also demonstrates that the Washington views Jakarta as a strategic partner playing a vital role in the Indo-Pacific region.
Super Garuda Shield 2026
A tangible manifestation of the bilateral defence relationship is the Super Garuda Shield joint exercise, which has been held since 2007 and has evolved into a multilateral exercise. In 2026, the exercise involved over 4,743 personnel from 13 participating nations and eight observer nations, making it the exercise with the highest number of participating countries in history.
It was held from August 31 to September 11 across various locations, including Jakarta, Bandung, Lampung, South Sumatra, and North Kalimantan, Super Garuda Shield 2026 emphasized cyber defence capabilities to support the establishment of the Indonesian National Armed Forces (TNI) cyber unit. TNI Commander General Agus Subiyanto emphasized that the primary objectives of the exercise were defence diplomacy and military capability exchange.
Various training scenarios were conducted to enhance interoperability, including special forces exercises featuring an airborne assault at Gatot Subroto Air Force Base in Lampung. During this exercise, 13 personnel from elite TNI units, including Special Forces Command (Kopassus), Amphibious reconnaissance Marine special forces (Taifib), and Rapid Reaction Force Corps (Korpasgat) conducted joint military training with U.S. special forces.
Military Education and Defence Industry Cooperation
In a recent meeting held in August 2026 between Indonesian Defence Minister Sjafrie Sjamsoeddin and U.S. Deputy Secretary of Defence Elbridge A. Colby, emphasis was placed on the commitment to enhancing the quality of defence human resources through continuous military education and training.
TNI personnel are encouraged to pursue education and training in the U.S., prioritizing professionalism and merit-based principles. This aligns with efforts to cultivate a generation of military leaders who understand the importance of bilateral relations and are prepared to address the complex regional security challenges of the future.
Beyond human resource development, bilateral cooperation in the defence industry sector also featured prominently in discussions between the two nations' defence ministers. Such cooperation is intended to support the development of national capabilities and strengthen Indonesia's defence self-reliance through partnerships that yield tangible benefits for both countries.
Strategic Partnership and Indonesia's Sovereignty
The bilateral defence relationship between Indonesia and the US has evolved into a comprehensive strategic partnership through the establishment of the Major Defence Cooperation Partnership. This partnership encompasses military modernization, human resource development, joint exercises, and increasingly complex operational cooperation.
Nevertheless, Indonesia is expected to remain consistent in upholding the principles of sovereignty and self-reliance, while ensuring that all cooperative activities are conducted based on mutual respect and yield tangible benefits for the national interest.
Looking ahead, this relationship is poised to remain a vital instrument for strengthening Indonesia's defence capabilities as it works to maintain security stability in the Indo-Pacific region. It is hoped that, through a balanced and professional approach, Indonesia can leverage this partnership to bolster its national defence posture without compromising the fundamental foreign policy principles it has long upheld.
