Key Security Developments

• Widespread Civil Unrest Over Forest Fires
  From October 20-24, 2026, coordinated student and civil-society protests took place in at least nine major cities across Indonesia, including Jakarta, Bandung, Jambi, Pontianak, and Gorontalo. Demonstrators demanded that the ongoing forest and land fire crisis be declared a national disaster, leading to heavy police deployment, use of tear gas, water cannons, and batons against protesters. This sustained civil unrest reflects significant public dissatisfaction with the government's environmental response and accountability for the fires, particularly in Sumatra and Kalimantan.

• "Sharp Knife 2026" Joint Counter-Terrorism Exercise with China
  From late October to early November 2026, the Chinese and Indonesian militaries commenced the "Sharp Knife 2026" army counter-terrorism joint training exercise in South China's Guangdong Province. This marks the third iteration of the series and the first in 14 years, focusing on joint mountain counter-terrorism rescue operations, including mountain climbing, special vehicle driving, helicopter rappelling, close-quarters assault, and manned-unmanned coordination. The exercise aims to deepen practical exchanges and cooperation between the two militaries, improving their joint operational capabilities against transnational and local crime and terrorism.

• New Multi-Nation Defense Pact (Badr MOU)
  On October 27, 2026, Indonesia signed the Badr Memorandum of Understanding (MOU) with Turkey, Qatar, and Pakistan in Doha. This agreement establishes a framework for defense cooperation and integration, encompassing joint research and development, training exchanges, and industrial capability building. The pact is seen as a strategic move to diversify Indonesia's defense partnerships, secure access to defense technology, and boost domestic production capabilities.

• Ongoing Recovery from National Data Center Ransomware Attack
  Indonesia continued to grapple with the aftermath of a significant ransomware attack that hit its national data center in June 2024, with reports from October 26-27, 2026, highlighting the severe and ongoing impact. The attack, attributed to a LockBit 3.0 variant dubbed "Brain Cipher," disrupted critical government services, most notably immigration processes at airports, and affected over 200 institutions. The incident exposed vulnerabilities in the country's cyber infrastructure, including outdated software and a lack of functional backups.

• Diplomatic Efforts at G20 on Maritime Conflicts and Global Resilience
  Foreign Minister Arrmanatha Nasir attended the G20 Foreign Ministers' Meeting in Atlanta, United States, on October 30-31, 2026. During the meeting, he urged the G20 to prevent maritime conflicts from escalating into a global crisis, advocating for stronger dialogue, de-escalation, and adherence to international law, including the 1982 United Nations Convention on the Law of the Sea (UNCLOS). Nasir also emphasized the interconnectedness of national, regional, and global resilience.

• Diplomatic Protest to Russia Over Citizen Recruitment for Ukraine War
  On November 1, 2026, Indonesia formally urged Russia to cease recruiting Indonesian citizens into its armed forces or affiliated military formations. This diplomatic intervention followed reports from Ukraine's military intelligence agency that an Indonesian national had been killed while fighting in Ukraine. Indonesia also raised concerns that some recruitment activities might involve human trafficking, emphasizing its commitment to protecting its citizens and maintaining its non-aligned foreign policy.

• SeaEagle Fire-Control Systems for Bung Tomo-class Frigates
  On October 28, 2026, UK-based Chess Dynamics secured a £3 million contract from Indonesian state defense electronics firm PT Len Industri to supply SeaEagle fire-control electro-optical systems for two Indonesian Navy Bung Tomo-class frigates, KRI Bung Tomo (357) and KRI John Lie (358). This acquisition is part of an ongoing effort to modernize the frigates and standardize their combat system configurations, enhancing the Indonesian Navy's operational capabilities.

• Joint Task Force with Singapore on Forest Fire Law Enforcement
  On October 27, 2026, Indonesia and Singapore agreed to establish a joint task force to enhance law enforcement against companies responsible for forest and land fires (karhutla). This cooperation will focus on information sharing, financial intelligence, cross-border evidence gathering, and tracing the financial flows of involved companies, with Singapore offering to share data on companies linked to the fires. The initiative aims to strengthen corporate accountability for the persistent environmental and diplomatic issue of transboundary haze.

• Exercise Keris Woomera with Australia Concludes
  In October 2026, Australia and Indonesia successfully concluded Exercise Keris Woomera, the Australian Defence Force's largest overseas training activity for the year, held in East Java and the Bali Sea. The nine-day exercise involved approximately 1000 Australian Defence Force (ADF) personnel and over 1200 members of the Indonesian National Armed Forces (TNI), conducting complex training across maritime, land, air, and cyber domains. The exercise strengthened interoperability and enhanced the two nations' ability to respond to shared regional security challenges, marking the first overseas deployment and firing of the HIMARS for the ADF and the first cyber integration training with Indonesia.

• Vessel Inspections for Maritime Safety Ahead of Holidays
  Indonesia's Transportation Ministry announced that from November 1-30, 2026, it would inspect 2,140 vessels in preparation for the 2026 Christmas and 2027 New Year holiday period. These inspections will cover vessel safety, pollution prevention, crew qualifications, cargo loading, and emergency preparedness to ensure maritime safety and readiness in busy sea routes. This proactive measure aims to reduce the risk of accidents and enhance overall maritime security during peak travel times.

Geopolitical Impact and Regional Dynamics

Indonesia's security developments during this period reflect its active pursuit of a "free and active" foreign policy, balancing relations with major global powers while addressing pressing domestic and regional concerns. The "Sharp Knife 2026" joint counter-terrorism exercise with China demonstrates a deepening of security cooperation with Beijing, particularly in non-traditional security threats. This collaboration, restarting after a 14-year hiatus, signals Indonesia's pragmatic approach to leveraging partnerships for specific security needs, potentially enhancing its counter-terrorism capabilities while also strengthening its strategic dialogue with China, which has expanded to include a joint foreign and defense ministerial mechanism established in 2025. This engagement with China, alongside existing economic ties, contributes to Beijing's growing influence in Southeast Asia.

The signing of the Badr Memorandum of Understanding with Turkey, Qatar, and Pakistan represents a significant diversification of Indonesia's defense partnerships beyond traditional Western suppliers and its growing engagement with Muslim-majority nations. This pact aims to foster joint research and development, training, and industrial capability building, potentially offering Indonesia critical defense technology and investment opportunities. This move could subtly shift regional dynamics by creating new axes of defense cooperation and reducing Indonesia's reliance on any single bloc, aligning with its non-aligned stance.

Indonesia's diplomatic efforts at the G20 Foreign Ministers' Meeting in Atlanta, where Foreign Minister Arrmanatha Nasir urged de-escalation of maritime conflicts and respect for UNCLOS, highlight its role as a proponent of regional stability and international law. This stance is particularly relevant given ongoing tensions in the South China Sea, where Indonesia, while not a claimant state in the same way as some ASEAN neighbors, maintains significant interests in freedom of navigation and regional peace. The call for a Code of Conduct in the South China Sea, a point of agreement with China, further underscores this. The formal protest to Russia regarding the recruitment of Indonesian citizens for the Ukraine war also reinforces Indonesia's commitment to protecting its nationals and its principled non-alignment in major power conflicts. Meanwhile, ongoing discussions with the US-ASEAN Business Council regarding a reciprocal trade agreement underscore Indonesia's efforts to maintain stable economic relations with the United States, a crucial partner for trade and investment, even as it diversifies its defense and diplomatic engagements.

Military and Defense Analysis

Indonesia is actively pursuing a robust military modernization program under President Prabowo Subianto, aiming to enhance its force posture and establish a credible deterrent. The country's defense spending for 2027 is earmarked at Rp 189 trillion ($10.5 billion), a slight increase from Rp 187 trillion ($10.4 billion) in 2026, though President Subianto has acknowledged it still lags behind some ASEAN neighbors like Singapore. This budget supports a multi-source procurement strategy, acquiring advanced military hardware from various international partners.

Recent and ongoing acquisitions include 42 French-made Rafale fighter jets, with six already delivered in May 2026, and preparations to receive the first Chinese J-10C fighters within six months, with orders potentially doubling from 42 to 84. Additionally, Indonesia has contracted for 48 Turkish-made KAAN fifth-generation fighter jets, with deliveries slated to begin in 2032. These procurements significantly boost Indonesia's air force capabilities. In the naval domain, the recent order for SeaEagle fire-control electro-optical systems for two Bung Tomo-class frigates underscores efforts to modernize existing assets and standardize combat systems. Furthermore, Indonesia received 12 US-made assault amphibious vehicles (AAVs) in September 2026, with the remaining 23 from a $23 million deal expected by November, and a further order of 70 AAVs being sought. These acquisitions enhance Indonesia's amphibious assault capabilities. The Exercise Keris Woomera with Australia in October 2026, which included the first overseas deployment of HIMARS for the ADF and cyber integration training, highlights Indonesia's commitment to improving interoperability and high-end military training with key regional partners across land, air, maritime, and cyber domains. The upcoming Indo Defence Expo & Forum 2026 in November will further showcase these modernization efforts and promote the growth of Indonesia's indigenous defense industry, with a strong emphasis on technology transfer in defense acquisitions.

Outlook and Forecast

In the short term (1-3 months), Indonesia is likely to continue experiencing elevated civil unrest, particularly if the forest and land fire crisis persists or if government accountability measures are perceived as insufficient. The ongoing protests, concentrated in Sumatra, Kalimantan, and major cities like Jakarta, could escalate, demanding sustained security deployments and potentially impacting economic activity. Concurrently, the nation will remain focused on strengthening its cybersecurity defenses following the significant ransomware attack on its national data center. Expect increased investment and policy initiatives aimed at bolstering critical infrastructure protection and data security, especially as the government works to recover fully from the breach.

Critical flashpoints and risk areas include the potential for continued social unrest stemming from environmental grievances and broader dissatisfaction with governance. The persistent threat of transnational terrorism, though currently managed by proactive counter-terrorism efforts, remains a concern, particularly with extremist groups adapting to online recruitment. Regionally, while Indonesia actively promotes stability, the broader South China Sea disputes continue to be a latent flashpoint, requiring careful diplomatic navigation. The ongoing modernization of Indonesia's military through diverse acquisitions, while enhancing deterrence, also necessitates careful management of interoperability and strategic alignment with various partners.

Indicators to monitor include the trajectory of protest activity and the government's response to the forest fire crisis, which will gauge internal stability. Progress in cybersecurity resilience, particularly the implementation of new safeguards and recovery from the data center attack, will be crucial. On the defense front, observe the pace of defense acquisitions and technology transfers, especially from China, Turkey, and France, as these will shape Indonesia's future military capabilities and strategic autonomy. Diplomatic engagements, particularly within ASEAN and with major powers, will indicate Indonesia's ability to balance its non-aligned foreign policy with evolving geopolitical realities.

Strategic recommendations for Indonesia include prioritizing and expediting comprehensive solutions to the forest and land fire crisis, addressing both immediate firefighting needs and long-term prevention and corporate accountability, potentially leveraging the joint task force with Singapore. A robust and urgent overhaul of national cybersecurity infrastructure is essential, moving beyond recovery to proactive defense mechanisms, regular audits, and enhanced training for government personnel. Furthermore, Indonesia should continue to diversify its defense partnerships and actively pursue technology transfers to foster a self-reliant defense industry, while carefully managing the geopolitical implications of these varied relationships. Finally, maintaining a strong, principled diplomatic voice in regional and international forums, particularly on maritime security and adherence to international law, will be vital for upholding its influence and contributing to regional stability.
