INS Sahyadri was at Guam in the Northern Pacific for participation in Exercise Malabar 2025, as stated in the PIB release dated 9 November 2025. For exam preparation, this update matters because it links India’s maritime security diplomacy with the Indo-Pacific, Quad cooperation, and naval interoperability. Exercise Malabar involves the navies of India, the United States, Japan and Australia, so the event is relevant not only as a defence exercise but also as a signal of regional stability and maritime cooperation.

Exercise Malabar began in 1992 as a bilateral India-US exercise and later evolved into a quadrilateral naval exercise. The 2025 edition was held in and around Guam. Official details state that the harbour phase included operational planning, discussions, alignment on communication protocols, familiarisation visits between participating nations, and sports fixtures. After the harbour phase, the sea phase involved ships and aircraft in naval drills focused on joint fleet operations, anti-submarine warfare, gunnery serials and flying operations. The 2025 edition also focused on anti-submarine warfare, surface warfare and air defence operations.

PIB described INS Sahyadri as an indigenously designed and constructed guided missile stealth frigate. It is also identified as a Shivalik-class stealth frigate commissioned in 2012. For static GK, the topic connects with classes of Indian naval ships, the evolution of major naval exercises, the Quad grouping, and maritime security in the Indo-Pacific. For mains, it can be used as an example of India’s defence diplomacy, interoperability with partner navies, and protection of the maritime commons.
