Key Security Developments

• Defense Acquisition Milestone: H145M Helicopters
  On October 15, 2026, Brunei's Ministry of Defence (MINDEF) signed the Customer Acceptance Test (CAT) certificate for the initial batch of Airbus H145M helicopters at Airbus Helicopters Deutschland (AHD) in Donauwörth, Germany. This marks a significant step in the acquisition of six H145M helicopters, ordered in April 2024, which are scheduled for delivery to Brunei in November 2026. These multi-role helicopters will replace the Royal Brunei Air Force's (RBAirF) decommissioned Bölkow BO 105 fleet, significantly enhancing operational capabilities for missions such as close air support (CAS) and aerial observation.

• Regional Cooperation on Transnational Crime (AMMTC)
  Brunei Darussalam actively participated in the 20th ASEAN Ministerial Meeting on Transnational Crime (AMMTC) and its related meetings, held in Makati City, Philippines, from October 19 to 21, 2026. Minister at the Prime Minister's Office (Security and Law) Dato Seri Setia Awang Haji Sufian Haji Sabtu called for faster cross-border cooperation to trace and freeze illicit proceeds from online scams, emphasizing that money moves faster than investigations. He also reaffirmed Brunei's commitment to tackling trafficking in persons, terrorism, violent extremism, money laundering, and illicit drug trafficking.

• Counter-Terrorism Policy Forum Co-Chairmanship
  Brunei and Malaysia are slated to co-chair the Senior Officials' Counter-Terrorism Policy Forum in 2027. This announcement was made during the seventh Sub-Regional Meeting on Counter Terrorism and Transnational Crime held in Jakarta, Indonesia, on October 24, 2026. The forum aims to strengthen regional collaboration and unify policy approaches among participating nations to more effectively address evolving threats from terrorism and violent extremism.

• Inaugural ASEAN Prosecutors/Attorneys General Meeting
  Brunei Darussalam hosted the Inaugural ASEAN Prosecutors/Attorneys General Meeting (APAGM) in Jerudong on October 20, 2026. The meeting, attended by the Secretary-General of ASEAN, aimed to discuss issues of common interest and concern among ASEAN Member States in fostering prosecutorial cooperation to strengthen the region's collective capacity to combat transnational crimes and promote the rule of law.

• Enhanced Cybersecurity Cooperation with Singapore
  Brunei Darussalam engaged in a ministerial-level bilateral meeting with Singapore around October 16, 2026, on the sidelines of the 11th Singapore International Cyber Week (SICW) 2026. Discussions focused on exploring closer cooperation in cybersecurity, including cyber threat information sharing, incident response, and the protection of critical information infrastructure. Brunei's participation in the SICW Ministerial Roundtable on October 13, 2026, also addressed AI-enabled cyber threats such as online scams and deepfakes.

• Cybersecurity Awareness within RBAF
  On October 14, 2026, the Cyber Defence Unit of the Joint Force Royal Brunei Armed Forces (JF RBAF) conducted a Cyber Security Awareness Briefing at Dewan Punai, Rimba Air Force Base. This briefing, attended by 80 officers and personnel of the Royal Brunei Air Force, aimed to enhance internal cybersecurity readiness within the military.

• Diplomatic Visit to Singapore by Prince 'Abdul Mateen

• Upgrade in U.S. Trafficking in Persons Report
  Brunei Darussalam was upgraded to Tier 2 in the 2026 Trafficking in Persons Report released by the United States Department of State on October 10, 2026. This advancement from the Tier 2 Watch List marks a second consecutive year of improvement and reflects international recognition of Brunei's sustained commitment to combating trafficking, including successful convictions, enhanced investigations, victim protection, and closer coordination among security agencies.

• Conclusion of CARAT Brunei 2026
  The annual Cooperation Afloat Readiness and Training (CARAT) Brunei 2026 exercise with the United States maritime forces concluded on September 18, 2026, in Bandar Seri Begawan and the South China Sea. This week-long bilateral exercise focused on shared maritime security challenges, enhancing interoperability, and building upon years of cooperation, involving U.S. Coast Guard and Navy assets alongside Royal Brunei Navy (RBN) vessels and a Sikorsky S-70i Black Hawk helicopter.

• 50 Years of Singapore-Brunei Defence Relations
  The Golden Jubilee Gallery commemorating 50 Years of Defence Relations between Brunei Darussalam and the Republic of Singapore was officially opened on October 14, 2026, at the Brunei Energy Hub. This event, following a Joint Parade at Muara Naval Base on October 10, 2026, underscored the enduring friendship, mutual trust, and defence cooperation between the two nations, with both Prime Minister Lawrence Wong of Singapore and His Majesty Sultan Haji Hassanal Bolkiah inspecting the parade.

• National Disaster Exercise 2026 (NDE-26) Review
  On October 13, 2026, three officers from the Joint Force Royal Brunei Armed Forces (JF RBAF) participated in the After Action Review (AAR) of the National Disaster Exercise 2026 (NDE-26). This review, held at the Ministry of Home Affairs, aimed to comprehensively assess and improve national disaster response capabilities and coordination, often requiring military support.

Geopolitical Impact and Regional Dynamics

Brunei's security developments during this period highlight its consistent foreign policy of active engagement, multilateral cooperation, and strategic balancing within the dynamic Indo-Pacific region. The nation's robust participation in regional forums like the ASEAN Ministerial Meeting on Transnational Crime (AMMTC) and the hosting of the ASEAN Prosecutors/Attorneys General Meeting (APAGM) underscore its commitment to ASEAN centrality in addressing shared non-traditional security threats. By advocating for faster cross-border cooperation against online scams and co-chairing the Senior Officials' Counter-Terrorism Policy Forum with Malaysia, Brunei reinforces its role as a responsible stakeholder in regional stability and law enforcement.

The high-level visit of His Royal Highness Prince 'Abdul Mateen to Singapore from October 21-23, 2026, along with the commemoration of 50 years of defense relations, reinforces the strong bilateral ties with a key ASEAN partner. Such engagements are crucial for maintaining ASEAN's cohesion and collective security amidst increasing geopolitical competition. Brunei's strategy of maintaining robust security partnerships with both the United States (as seen with the recently concluded CARAT Brunei 2026 exercise) and other major powers, while also reaffirming defense ties with China (reported slightly outside this period but relevant to its balanced approach), exemplifies its efforts to leverage cooperation for defense modernization and maritime security without exclusive alignment. This balanced approach contributes to regional stability rather than exacerbating tensions.

The upgrade in the U.S. Trafficking in Persons Report to Tier 2 is a significant diplomatic achievement, reflecting international recognition of Brunei's commitment to human rights and rule of law. This positive assessment can enhance Brunei's standing in international cooperation efforts and potentially attract further partnerships in combating transnational crimes. Furthermore, Brunei's active participation in discussions on AI-enabled cyber threats at the Singapore International Cyber Week demonstrates its recognition of advanced cyber risks and its proactive stance in bolstering digital defenses through regional partnerships, which is vital for protecting critical information infrastructure across the region.

Military and Defense Analysis

Brunei's military and defense posture during this period is characterized by a clear focus on modernization and enhancing interoperability with key partners. The signing of the Customer Acceptance Test for the first batch of Airbus H145M helicopters on October 15, 2026, represents a significant step in the modernization program of the Royal Brunei Air Force (RBAirF). These six new multi-role helicopters, replacing the aging Bölkow BO 105 fleet, will bolster the RBAirF's capabilities in critical areas such as close air support, aerial observation, and potentially combat search and medical evacuation. This acquisition reflects a strategic investment to maintain a modern and capable air force, ensuring it can effectively contribute to national defense and regional security operations despite its modest size.

The recent conclusion of CARAT Brunei 2026 in September 2026, involving the Royal Brunei Armed Forces (RBAF) and U.S. maritime forces, underscores Brunei's commitment to strengthening its maritime security capabilities and fostering interoperability. Exercises like CARAT, which included U.S. Coast Guard and Navy assets alongside Royal Brunei Navy (RBN) vessels, are crucial for developing shared maritime domain awareness and refining tactical skills in areas such as anti-submarine warfare and maritime interdiction operations in the South China Sea. While specific defense spending figures or major new arms acquisitions beyond the H145M were not reported in this period, the emphasis on joint exercises and internal capability building, such as the Cyber Security Awareness Briefing for RBAirF personnel, suggests a continued investment in practical readiness and adaptation to contemporary security landscapes.

Outlook and Forecast

In the short-term (1-3 months), Brunei is expected to continue its trajectory of defense modernization with the anticipated delivery of the first batch of Airbus H145M helicopters in November 2026. This will initiate a period of integration and training for the Royal Brunei Air Force, focusing on operationalizing these new multi-role platforms. Concurrently, Brunei will likely maintain its active engagement in ASEAN-led security forums, particularly in cybersecurity, as the ASEAN Cybersecurity Cooperation Strategy 2026-2030 begins its implementation phase, and in counter-terrorism, preparing for its co-chairmanship of the Senior Officials' Counter-Terrorism Policy Forum in 2027. Diplomatic efforts will continue to reinforce bilateral ties, building on the momentum from Prince 'Abdul Mateen's visit to Singapore and ongoing cooperation with key partners.

Critical flashpoints and risk areas for Brunei remain primarily external, centered on the broader South China Sea disputes, although no direct incidents involving Brunei were reported in this period. The ongoing presence of major power naval assets and competing claims in the region necessitate Brunei's continued focus on maritime domain awareness and interoperability with partners like the U.S. and Singapore. Internally, the rising threat of cybercrime and online radicalization, highlighted at the AMMTC, poses a persistent risk to national security and critical infrastructure, demanding sustained attention to digital defenses and public awareness campaigns.

Indicators to monitor include the smooth integration and operational readiness of the new H145M helicopters, the progress of regional cybersecurity initiatives, and any shifts in the dynamics of the South China Sea. The effectiveness of cross-border cooperation mechanisms against transnational crime, particularly online scams and human trafficking, will also be a key measure of Brunei's security resilience. Strategic recommendations include continued investment in cyber defense capabilities and human capital development to counter evolving digital threats. Brunei should also explore further opportunities for multilateral maritime security exercises to enhance collective response capabilities in the South China Sea and reinforce its commitment to a rules-based international order. Finally, leveraging its improved standing in human trafficking reports to drive further regional cooperation and best practice sharing would solidify its leadership in this area.
