Key Security Developments

• Defense Acquisitions and Arms Deals
  On May 18, 2026, Indonesia received six French-made Rafale fighter jets, four Dassault Falcon 8X aircraft, and two Airbus A400M Atlas transport planes at Halim Perdanakusuma Air Force Base in Jakarta. This delivery is part of an $8.1 billion deal signed in 2022 for a total of 42 Rafale fighters, with President Prabowo Subianto emphasizing that these acquisitions are crucial for strengthening Indonesia's defense capabilities and serving as a deterrent in an uncertain global geopolitical landscape.

• Diplomatic Relations with France
  President Prabowo Subianto's visit to Paris in late May 2026, concluding on May 28, further deepened ties with France, with discussions aimed at elevating bilateral relations through a Comprehensive Strategic Partnership. The talks highlighted defense, renewable energy, education, and research as key areas of cooperation, reflecting Indonesia's push to strengthen its defense capabilities while France expands its Indo-Pacific engagement.

• Major Defense Cooperation Partnership with the US
  Indonesia and the United States elevated their military ties to a Major Defense Cooperation Partnership (MDCP) in April 2026, a designation that commits both nations to co-develop sophisticated asymmetric capabilities and next-generation defense technologies. This partnership, reaffirmed by US Secretary of War Pete Hegseth on May 30, 2026, provides Indonesia with access to cutting-edge capabilities in maritime, subsurface, and autonomous systems, deepening its integration into the Indo-Pacific security architecture without requiring permanent basing.

• Defense Cooperation with Japan
  In May 2026, Jakarta and Tokyo signed a Defense Cooperation Arrangement covering humanitarian assistance, disaster relief, maritime security, joint exercises, and potential exchanges in defense technology and equipment. This agreement coincides with Japan's relaxation of its decades-old restrictions on arms exports, further diversifying Indonesia's defense partnership portfolio.

• Cybersecurity Threat Surge
  Indonesia experienced a staggering 5.5 billion cyberattacks in 2025, representing a 714 percent increase compared to the annual average from 2020-2024. The National Cyber and Crypto Agency (BSSN) reported an additional 1.52 billion attacks in the first three and a half months of 2026, primarily targeting government infrastructure, the economy, and national security. In response, Indonesia is actively strengthening its national cybersecurity system.

• Domestic Security Incidents and "Shoot-on-Sight" Policies
  Human Rights Watch expressed concern on June 05, 2026, over new "shoot-on-sight" policies implemented by Indonesian authorities to combat street crime, particularly muggings, in areas such as Jakarta, Makassar, Lampung province, and Bekasi. These policies involve joint police and military task forces, raising alarms about potential unlawful use of force and the expanding role of the military in civilian law enforcement.

• Maritime Security in the South China Sea
  Indonesia continues to face "grey-zone tactics" from China in the North Natuna Sea, which involves combining civilian activities, maritime law enforcement, and diplomacy to gradually expand influence without triggering open conflict. These incursions have tested Indonesia's sovereignty, with the Indonesian coast guard expelling Chinese vessels on several occasions.

• Regional Maritime Security Cooperation
  Indonesia, the Philippines, and Vietnam are actively exploring enhanced security cooperation focused on maritime order in the South China Sea. This includes practical cooperation at sea, particularly between coast guards, and builds upon existing bilateral arrangements such as the Indonesia-Vietnam agreement demarcating their overlapping exclusive economic zones (EEZ) in the North Natuna Sea.

• Military Modernization Funding Challenges
  President Prabowo's ambitious military modernization plan, which includes an allocation of Rp 337 trillion for defense in 2026 (with Rp 83 trillion for arms upgrades), faces economic challenges. A weakening rupiah and narrowing fiscal space are creating logistical complexities and interoperability risks due to the diversification of weapons systems from various suppliers.

• Presidential Diplomacy and Scrutiny
  President Prabowo Subianto's frequent overseas trips, including his fourth visit to France in late May, have drawn public scrutiny regarding their transparency, urgency, and tangible benefits. While acknowledged as reflecting specific diplomatic priorities and a non-aligned hedging posture, critics question the cost-effectiveness of these engagements amidst domestic economic challenges.

• Indonesia-Malaysia Bilateral Cooperation
  On June 4, 2026, Indonesia and Malaysia reaffirmed their commitment to strengthening cooperation across various sectors during the 17th Indonesia-Malaysia Joint Commission on Bilateral Cooperation (JCBC) in Jakarta. Discussions included economic relations, citizen protection, regional stability, and efforts to achieve world peace, marking a significant re-engagement after the last JCBC dialogue in 2018.

Geopolitical Impact and Regional Dynamics

Indonesia's recent security and diplomatic activities underscore its strategic positioning as a significant middle power in the Indo-Pacific, actively shaping regional dynamics while maintaining its traditional "free and active" foreign policy. The deepening of defense ties with both the United States and France, alongside new cooperation with Japan, reflects a calculated diversification strategy to enhance military capabilities and avoid overreliance on any single major power. This approach, while geopolitically elegant, also highlights Indonesia's intent to bolster its deterrence capabilities in an increasingly uncertain global landscape.

The ongoing challenges in the South China Sea, particularly China's persistent "grey-zone tactics" in the North Natuna Sea, remain a critical focal point for Indonesia. Jakarta's efforts to push for the completion of a Code of Conduct (CoC) for the South China Sea by 2026, coupled with burgeoning maritime security cooperation with the Philippines and Vietnam, demonstrate a proactive stance to uphold international law and maintain regional stability. This regional collaboration is vital in countering unilateral actions and ensuring the security of crucial maritime trade routes.

Indonesia's diplomatic engagements, including President Prabowo's frequent international visits, signal a robust, albeit scrutinized, foreign policy agenda. While these trips aim to secure investments and strengthen defense cooperation, they also reflect Indonesia's balancing act between major global powers like the US, China, and Russia. The decision to suspend involvement in Trump's "Board of Peace" in March 2026, driven by domestic pressure and a commitment to its "bebas-aktif" principles, particularly concerning the Israel-Palestine conflict, further illustrates Indonesia's independent foreign policy and its role as a voice for the broader Muslim world. This complex interplay of bilateral and multilateral engagements positions Indonesia as a key actor influencing the broader strategic landscape of the Indo-Pacific.

Military and Defense Analysis

Indonesia's military is undergoing its most comprehensive restructuring and modernization in decades, driven by a strategic imperative to safeguard its vast archipelagic territory and project deterrence. The recent acquisition of six French-made Rafale fighter jets, four Dassault Falcon 8X aircraft, and two Airbus A400M Atlas transport planes on May 18, 2026, marks a significant step in upgrading its air force capabilities. These additions are part of a larger $8.1 billion deal for 42 Rafales, reflecting a substantial investment in high-end military hardware. The modernization program also includes orders for 48 Kaan fighters from Turkey and two French Scorpene-class submarines, alongside evaluations of US F-15EX and China's J-10C, showcasing a deliberate policy of diversifying suppliers to avoid overreliance on any single country.

Defense spending trends indicate a significant commitment, with the government allocating Rp 337 trillion for defense in 2026, of which Rp 83 trillion is earmarked for arms upgrades. This increased budget aims to support long-term modernization targets, covering the maintenance of warships, naval vessels, launcher systems, and combat vehicles. However, this ambitious modernization faces an economic reality check, with a weakening rupiah and narrowing fiscal space posing challenges. Experts warn that operating diverse weapons systems from multiple platforms could lead to logistical chaos and interoperability risks, suggesting a need to prioritize improving existing systems' interoperability alongside new acquisitions. The military reorganization also involves creating new regional commands and strengthening air and naval components to enhance territorial coverage and integrate with local communities, adapting the defense structure to contemporary challenges.

Outlook and Forecast

In the short-term (1-3 months), Indonesia is expected to continue its assertive military modernization drive, albeit with increasing scrutiny over its economic implications. The delivery schedule for further Rafale jets and other defense equipment will likely proceed, reinforcing Indonesia's air and maritime defense posture. Simultaneously, the government will likely intensify efforts to strengthen its cybersecurity infrastructure in response to the escalating threat landscape, potentially leading to new policy announcements or international collaborations in this domain. Diplomatic engagements, particularly with ASEAN partners on maritime security and the South China Sea Code of Conduct, will remain a priority, with Jakarta aiming to finalize the CoC this year.

Critical flashpoints and risk areas include the North Natuna Sea, where continued Chinese grey-zone tactics could lead to increased friction and potential maritime incidents. Domestically, the implementation of "shoot-on-sight" policies to combat street crime, particularly in major cities like Jakarta, Makassar, Lampung, and Bekasi, presents a significant risk of human rights abuses and could fuel public discontent, potentially leading to localized protests or increased scrutiny from international human rights organizations. The ongoing threat of terrorism from groups like Jemaah Islamiyah and Jamaah Ansharut Daulah also remains a persistent concern, requiring continuous counter-terrorism operations.

Indicators to monitor include the stability of the Indonesian rupiah and its impact on defense procurement, as economic constraints could force adjustments to modernization plans. Progress on the South China Sea Code of Conduct negotiations will be a key indicator of regional diplomatic effectiveness. Domestically, the public and civil society's reaction to the military's expanded role in law enforcement and the effectiveness of new cybersecurity measures will be crucial. Any significant increase in maritime incidents in the North Natuna Sea or major cyberattacks on government systems would signal an escalation of existing threats.

Strategic recommendations for Indonesia include prioritizing the interoperability of its diverse defense systems to maximize efficiency and reduce logistical burdens, especially given fiscal constraints. Enhancing regional intelligence sharing and joint maritime patrols with ASEAN partners is crucial for effectively addressing challenges in the South China Sea. Furthermore, a transparent review of the "shoot-on-sight" policies and a clear delineation of military and police roles in domestic law enforcement are essential to uphold human rights and maintain public trust. Investing in robust, domestically developed cybersecurity solutions and fostering public-private partnerships in this sector will be vital to counter the rapidly evolving cyber threats.
