What Is Exercise Malabar?

Exercise Malabar is a major multilateral naval exercise involving the navies of India, the United States, Japan and Australia.

The exercise was originally launched in 1992 as a bilateral naval exercise between India and the United States.

Japan became a permanent participant in 2015, while Australia rejoined the exercise in 2020, establishing the present four-nation format.

The exercise focuses on improving coordination, communication, interoperability and maritime operational capabilities among the participating navies.

Participating Countries in Malabar 2026

All four participating countries are also members of the Quadrilateral Security Dialogue, commonly known as the Quad.

However, Exercise Malabar is a naval exercise rather than a formal military exercise conducted under a Quad military command structure.

1. Harbour Phase

The harbour phase focuses on professional exchanges, operational discussions and coordinated planning among participating naval forces.

Major activities include:

• Exchange of maritime expertise and best practices.

• Discussions on naval procedures and communication.

• Strengthening mutual understanding and cooperation.

2. Sea Phase

The phase aims to improve practical coordination, interoperability and operational familiarity among the participating navies.
