The MDCP is designed as a primary framework to guide future defense cooperation. Through this agreement, both countries reaffirm their joint commitment to maintaining peace and stability in the Indo-Pacific region.

Structurally, the MDCP rests on three main pillars implemented based on mutual respect and national sovereignty:

First, Military Modernization and Capacity Building; Second, Professional Military Training and Education; and Third Joint Exercises and Operational Cooperation.

Under the MDCP umbrella, the United States and Indonesia will explore various cutting-edge initiatives that have been agreed upon. This includes joint development of advanced asymmetric capabilities, pioneering next-generation defense technology in the maritime, subsurface, and autonomous systems sectors. 

In addition, both countries agreed to cooperate in maintenance, repair, and inspection (MRO) support to enhance operational readiness of defense equipment.

As a symbol of strengthening partnership and a reflection of deep trust between the two countries, both leaders also committed to enhancing joint special forces exercises. 

This step is expected to advance shared security interests and strengthen relationships between U.S. and Indonesian military personnel through the expansion of professional military education opportunities and the establishment of a defense alumni network.

This partnership represents the ongoing development of the bilateral defense relationship between Indonesia and the U.S. that has been built over decades.

Both countries recognize each other as important partners and reaffirm their commitment to cooperate based on mutual respect, sovereignty, and shared interests in achieving regional peace and stability.

The U.S. Department of War and the Indonesian Ministry of Defense express their readiness to deepen investment in more intensive cooperation under the MDCP framework.

Sovereignty Controversy

The MDCP agreement previously sparked sensitive issues in the field of airspace sovereignty, as Indonesia was reported to be opening free access for U.S. military aircraft to cross its airspace.

This news became widespread after reports emerged that the United States had requested broad access, even referred to as "blanket overnight access" or flexible crossing permission, including for sudden operations. There was even a narrative circulating that Indonesia had approved this proposal.

The Indonesian Ministry of Defense immediately responded to foreign media reports implying a final agreement on U.S. military air transit access in Indonesian airspace.

In a written statement, the Indonesian Ministry of Defense clarified that the circulating document is an initial draft still under internal and inter-agency discussion. 

The document is not a final agreement, does not have binding legal force, and cannot be used as a basis for official policy of the Government of the Republic of Indonesia, as of Monday (April 13, 2026).

The Indonesian Ministry of Defense emphasized that any defense cooperation discussions with other countries are always conducted within the framework of prioritizing national interests, fully maintaining the sovereignty of the Unitary State of the Republic of Indonesia, and guided by applicable national and international laws.

The Indonesian Ministry of Defense affirmed that authority, control, and supervision over Indonesian airspace are entirely within the jurisdiction of Indonesia. Any possible arrangement will still guarantee Indonesia's full authority to approve or reject any activities in national airspace.

The Indonesian Ministry of Defense also stressed that any planned activities must comply with each country's national laws. In the context of Indonesia, this means the entire process must follow legislation, institutional mechanisms, and the country's political decisions. There is no room for unilateral implementation outside of Indonesian law.
