The navies of India, the United States, Japan and Australia have commenced Exercise MALABAR 2026 in waters south of Japan’s Kanto region. Running from November 5 to November 12, the multinational naval exercise aims to strengthen maritime cooperation, improve operational coordination and enhance the combined capabilities of the four Quad partner nations.
India is participating with its indigenously built Guided Missile Stealth Frigate INS Sahyadri, which arrived at Yokosuka Naval Base in Japan on November 4. The warship received a welcome from the Japan Maritime Self-Defense Force (JMSDF), reflecting the growing maritime partnership between the two countries.
The exercise involves naval assets from all four participating nations, including Japan’s helicopter carrier JS Ise, Mogami-class frigate JS Mogami, a submarine and P-1 maritime patrol aircraft. Australia has deployed HMAS Stuart and a P-8A Poseidon maritime patrol aircraft, while the United States is contributing naval vessels and maritime patrol aircraft.
MALABAR 2026 includes harbour and sea phases, featuring professional exchanges, coordinated planning and advanced maritime operations. The drills cover multiple operational domains, including surface, underwater, air and information warfare. Anti-submarine and anti-surface warfare activities will also help participating forces improve their ability to detect, track and respond to maritime threats.
The exercise holds strategic importance as the four countries seek to strengthen regional security and protect freedom of navigation across the Indo-Pacific. Regular joint naval engagements provide opportunities to improve communication, develop mutual understanding and enhance interoperability between their respective forces.
For India, INS Sahyadri’s participation highlights the Indian Navy’s commitment to strengthening international maritime partnerships and supporting regional security. The deployment also aligns with India’s MAHASAGAR vision, which promotes mutual cooperation, maritime security and growth across regions.
Originally launched as a bilateral exercise between India and the United States in 1992, MALABAR has evolved into a significant multilateral naval engagement with Japan and Australia joining the framework. The 2026 edition further demonstrates the Quad partners’ commitment to maintaining a stable, secure and Free and Open Indo-Pacific.
