Indian Coast Guard Ship Shaunak Begins Quad-at-Sea Observer Mission to Australia
India Joins Quad Maritime Observer Mission Aboard ICG Ship Shaunak.
Quad-at-Sea Ship Observer Mission: The Indian Coast Guard has stepped up maritime cooperation with its Quad partners, with ICG Ship Shaunak sailing from Chennai for Perth, Australia, on 25 September as part of the Quad-at-Sea Ship Observer Mission.
The mission brings together personnel from India, Australia, Japan and the United States for shipboard activities and professional exchanges. It is intended to improve interoperability between the four countries’ maritime forces while strengthening coordination and mutual understanding in the Indo-Pacific.
The deployment represents a practical element of the wider maritime cooperation among the four Quad countries and follows their shared commitment to maintaining a free, open, inclusive and rules-based maritime order in the region.
Officers from four Quad countries join the ship
Six officers, referred to as Sea Riders, have embarked on Shaunak for the mission.
The group includes two officers from India, two from Japan, one from Australia and one from the United States.
During the voyage, the officers will participate in activities conducted aboard the Indian Coast Guard vessel. The exchanges are intended to give personnel from the four countries an opportunity to work alongside one another, understand different operational practices and build professional relationships.
Such shipboard engagements can provide practical experience in coordinating between maritime forces that have their own procedures, organisational structures and operational methods.
The mission therefore goes beyond a symbolic display of cooperation. Its emphasis is on personnel-to-personnel engagement and developing familiarity between the participating services.
What is the Quad-at-Sea mission?
The Quad comprises India, Australia, Japan and the United States, four countries that have increasingly focused on cooperation in the Indo-Pacific.
The Quad-at-Sea Ship Observer Mission provides a maritime setting for this cooperation. Rather than being centred solely on meetings between senior officials, the initiative brings serving personnel together aboard a ship and allows them to participate in professional activities during the deployment.
The objective is to strengthen interoperability — the ability of different maritime forces to work effectively together — while developing coordination and trust.
For coast guards and other maritime agencies, such cooperation can be particularly relevant because their responsibilities extend across a broad range of activities, including maritime safety, security and maintaining awareness of activity at sea.
Mission linked to Quad foreign ministers’ commitment
The Indian Coast Guard said the initiative is aligned with the Quad Foreign Ministers’ Joint Statement of 26 May 2026.
The mission reflects the four countries’ stated commitment to a maritime environment based on freedom, openness, inclusiveness and rules.
The Indo-Pacific is home to some of the world’s busiest shipping routes and is strategically important to the economies of the countries surrounding it. Maintaining secure maritime routes and improving cooperation between countries therefore remain important areas of regional engagement.
The observer mission provides one avenue for turning broader diplomatic commitments into practical interaction between maritime personnel.

Why interoperability matters at sea
Ships from different countries may need to coordinate during a range of maritime activities. Effective cooperation can depend on personnel understanding how partner forces communicate, organise operations and respond to situations at sea.
Observer missions offer a relatively direct way to develop that understanding.
By spending time aboard Shaunak, the Sea Riders can observe the Indian Coast Guard’s procedures and participate in professional activities while also sharing their own experience.
The Indian Coast Guard said the mission has been designed to enhance interoperability, strengthen coordination and build mutual trust among the participating countries.
The benefits can therefore extend beyond the duration of the voyage. Professional relationships developed during such missions can provide a foundation for future interactions and maritime cooperation.

India’s MAHASAGAR vision
The deployment also forms part of India’s broader maritime outlook, described by the government through the MAHASAGAR vision — Mutual and Holistic Advancement for Security and Growth Across Regions.
The Indian Coast Guard said the mission underscores this approach and its commitment to collective engagement and professional linkages across the Indo-Pacific.
For the Coast Guard, maritime cooperation is closely connected to maintaining a secure maritime environment. Engagement with partner countries can help build shared understanding while supporting practical cooperation among regional maritime forces.
ICG Shaunak heads to Perth
With Shaunak departing Chennai on 25 September, the mission now moves from its Indian port of departure towards Perth, Australia.
The voyage will bring together officers from all four Quad countries aboard an Indian Coast Guard ship, providing a practical setting for professional exchanges.
The deployment comes as India, Australia, Japan and the United States continue to develop cooperation across the Indo-Pacific. While the mission is focused on maritime personnel and shipboard engagement, its wider significance lies in building habits of cooperation between the four countries.
For the Indian Coast Guard, the Quad-at-Sea mission represents another opportunity to deepen professional links with its counterparts and contribute to maritime cooperation in the Indo-Pacific.
