Indonesia is a critical U.S. partner in the heart of the Indo-Pacific. With its vast archipelago, maritime security is a principal Indonesian concern. Additionally, the U.S. is deeply invested in maintaining a free and open Indo-Pacific, as affirmed in the most recent National Security Strategy. This thesis analyzes how the United States can advance its interests in this region through cooperation with Indonesia to improve Indonesian maritime security. Through application of operational design, derived from U.S. military doctrine, across the instruments of national power, this research analyzes how Indonesia combats three of its primary maritime security problems: illegal, unreported, and unregulated fishing; unresolved borders; and maritime piracy and armed robbery. Founded on the tenets of the U.S.-Indonesia bilateral relationship, this study identifies gaps in Indonesia's approach to these maritime security problems and recommends ways the U.S. can help to close these gaps. This U.S. assistance will strengthen Indonesian maritime security and will advance U.S. regional interests. These actions aim to deepen this strategic relationship and maintain a free and open Indo-Pacific.
