# US, Indonesia Sign Major Defense Agreement on Maritime Tech & Co-production

**Washington (TDI): **The United States and Indonesia signed a new defense framework, called the Major Defense Cooperation Partnership (MDCP), at the Pentagon on Monday.

US Secretary of War Pete Hegseth hosted Indonesian Defense Minister Sjafrie Sjamsoeddin for the formal signing ceremony. The agreement rests on three foundational pillars: military modernization and capacity building, training and professional military education, and exercises and operational cooperation.

Both countries will explore co-development of sophisticated asymmetric capabilities and next-generation defense technologies in maritime, subsurface, and autonomous systems domains. They also agreed to expand joint special forces training and improve maintenance, repair, and overhaul support.

The MDCP also includes enhanced cooperation in multinational exercises such as Super Garuda Shield and explores cutting-edge initiatives in asymmetric capabilities.

Pete Hegseth said the partnership signifies the strength and potential of the security relationship. He noted that the two countries already conduct more than 170 joint military exercises each year.

Sjafrie Sjamsoeddin expressed great enthusiasm to continue developing the defense relationship, stating both sides are working on the basis of mutual respect and mutual benefit.

The agreement underscores Indonesia’s balanced approach to strengthening defense ties with major powers while maintaining its non-aligned foreign policy. It coincides with Indonesian President Prabowo Subianto’s visit to Russia.

Both nations have maintained formal diplomatic relations for more than 75 years, and this new framework builds on decades of cooperation to address emerging security challenges in the Indo-Pacific.
