Indian Navy ships INS Sahyadri and INS Kulish took part in the 23rd ADMM-Plus Experts' Working Group on Maritime Security Joint Cooperation Activity at Subic Bay in the Philippines. The activity ran from 21 to 25 September 2026 and was hosted by the Philippine Navy with Japan as co-chair. It covered port and sea phases including search and rescue, hydrographic survey and medical evacuation drills. India linked its participation to the Act East Policy and its maritime vision for the region. The item is central to questions on ASEAN-led defence mechanisms.
Indian Navy ships INS Sahyadri and INS Kulish took part in the 23rd ADMM-Plus Experts' Working Group on Maritime Security Joint Cooperation Activity at Subic Bay, Philippines, from 21 to 25 September 2026. The activity was hosted by the Philippine Navy and co-chaired by Japan, and it brought together navies from ASEAN member states and dialogue partner countries. It ran in two phases, one in harbour and one at sea.
The activity was held from 21 to 25 September 2026 at Subic Bay in the Philippines. Subic Bay lies on the western coast of Luzon and faces the South China Sea, one of the world's busiest and most contested maritime zones. Its deep natural harbour made it a long-standing naval base, and it remains a working port for multinational naval activity.
The ASEAN Defence Ministers' Meeting-Plus was created as the enlarged form of the ASEAN Defence Ministers' Meeting, bringing eight dialogue partners into a defence forum led by ASEAN. Its first meeting was held in Hanoi in 2010. India has been a participant from the beginning, and Indian Navy ships have joined its maritime security activities in successive cycles. This participation sits within India's Act East Policy, which succeeded the earlier Look East Policy and shifted the emphasis from trade engagement to strategic and security cooperation with Southeast Asia.
India participates in ADMM-Plus as one of the eight dialogue partners alongside Australia, China, Japan, New Zealand, the Republic of Korea, Russia and the United States. Unlike a formal alliance such as NATO, the ADMM-Plus has no mutual defence obligation and works instead through practical cooperation in working groups. This suits India's position, which favours issue-based partnerships over treaty alliances. Hosting duties and co-chairing rotate among members, so influence in the forum comes from consistent participation rather than from formal seniority.

PYQ 2:
Consider the following statements about the 23rd ADMM-Plus maritime security activity:
It was held at Subic Bay in the Philippines.
India was represented by INS Sahyadri and INS Kulish.
It consisted only of a harbour phase with no sea phase.
Which of the above statements is/are correct?
A) 1 only
B) 1 and 2 only
C) 2 and 3 only
D) All of the above
Answer: B
Explanation: Statements 1 and 2 are correct. Statement 3 is wrong because the activity had both a port phase and a sea phase.
PYQ 3:
Assertion (A): The drills chosen for the ADMM-Plus maritime security activity were humanitarian and safety tasks rather than combat exercises.
Reason (R): Such tasks allow navies with differing strategic positions to cooperate without political difficulty.
A) Both A and R are true, and R is the correct explanation of A
B) Both A and R are true, but R is not the correct explanation of A
C) A is true but R is false
D) A is false but R is true
Answer: A
Explanation: The activity covered search and rescue, hydrographic survey, medical evacuation and assistance to a distressed vessel, and it is precisely their non-combat character that lets participants with different strategic outlooks work together.
Question 1 (150 words): Examine the significance of India's participation in ADMM-Plus maritime security activities.
India's deployment of INS Sahyadri and INS Kulish to the 23rd ADMM-Plus Experts' Working Group on Maritime Security activity at Subic Bay, from 21 to 25 September 2026, reflects a settled policy rather than an occasional gesture. The ADMM-Plus links ASEAN member states with eight dialogue partners, and India has been part of it since its first meeting in Hanoi in 2010.
The practical value lies in interoperability. The activity covered search and rescue, hydrographic survey, medical evacuation, aircraft deck operations and assistance to a distressed vessel, tasks that regional navies actually perform together during emergencies. Agreeing on common procedures in a planned activity is what makes cooperation possible in an unplanned one.
The strategic value is equally clear. Participation anchors India within ASEAN-centred security architecture, consistent with the Act East Policy. The way forward is sustained presence across working groups rather than selective participation.
Question 2 (250 words): Discuss the place of ASEAN-led defence mechanisms in India's Indo-Pacific strategy.
India's Indo-Pacific approach rests on issue-based partnerships rather than treaty alliances, and ASEAN-led mechanisms fit that preference precisely. The ADMM-Plus, which first met in Hanoi in 2010, brings ASEAN member states together with eight dialogue partners — Australia, China, India, Japan, New Zealand, the Republic of Korea, Russia and the United States. It carries no mutual defence obligation and works instead through Experts' Working Groups on themes such as maritime security.
The 23rd Experts' Working Group on Maritime Security activity at Subic Bay, held from 21 to 25 September 2026, illustrates how this operates in practice. The Philippine Navy hosted it with Japan as co-chair, pairing an ASEAN state with a dialogue partner so that neither side alone sets the agenda. India sent INS Sahyadri, a stealth frigate, and INS Kulish, a missile corvette. The programme ran in a port phase of expert exchanges and tabletop exercises and a sea phase of search and rescue, hydrographic survey, medical evacuation and distressed vessel assistance.
Three considerations explain why this matters to India. Geographically, Subic Bay faces the South China Sea, through which a very large share of India's seaborne trade passes. Politically, ASEAN centrality lets India engage the region without being drawn into bloc rivalry. Institutionally, the Act East Policy has made security cooperation, not only trade, the substance of India's Southeast Asia engagement.
The limitation is that consensus-based forums move slowly and avoid contentious issues. The balanced conclusion is that ASEAN mechanisms are a necessary foundation for India, to be maintained alongside, not in place of, its other regional partnerships.
