The Indian Navy and the Republic of Korea Navy (RoKN) commenced their inaugural bilateral naval exercise, IN-RoKN, on October 13, 2025, at the Busan Naval Base, South Korea. INS Sahyadri, a Shivalik-class stealth frigate, participated alongside South Korea's ROKS Gyeongnam.

The exercise featured both harbour and sea phases, including coordinated maneuvers, cross-deck visits, professional exchanges, and cross-training sessions. This historic initiative marks a significant step in India's strategic outreach in East Asia and strengthens bilateral defence ties.
