Exercise Malabar 2025 is a major Quad naval exercise held from November 10–18, 2025, near Guam in the West Pacific, involving India, the United States, Japan, and Australia. The drill focuses on strengthening interoperability, regional security, and joint operational readiness among the four nations.
The exercise featured two phases — Harbour Phase (Nov 10–12) and Sea Phase (Nov 13–17) — and included advanced naval platforms such as India’s INS Sahyadri and Australia’s HMAS Ballarat with a P-8A Poseidon aircraft.
Started in 1992 as a bilateral India–US exercise, Malabar expanded to include Japan in 2015 and Australia in 2020, evolving into a key Quad maritime cooperation platform. It reflects the nations’ shared commitment to freedom of navigation, regional stability, and a rules-based Indo-Pacific order.
