INS Sahyadri Reaches Busan for India-Korea Naval Drill

INS Sahyadri, a guided missile stealth frigate designed and built in India, entered Busan Naval Harbour in the Republic of Korea on 26 October 2026. The ship is there for the India-Republic of Korea Navy (IN-RoKN) Bilateral Exercise, and the Republic of Korea Navy gave the visiting frigate a warm reception on arrival.

What the two navies will do

The engagement is built in two parts, which is the usual pattern for a bilateral naval exercise. The first is the harbour phase, carried out while the ship is alongside. Sailors and officers of both navies hold professional exchanges, visit each other's decks, train together and play sporting fixtures. The point of these days in port is not display but transfer: each side explains how it handles a situation at sea, and the other adopts what works. The Commanding Officer of INS Sahyadri will also call on senior officials of the host navy.

The sea phase

Once the harbour programme ends, the two navies move out for coordinated activities at sea. INS Sahyadri will operate alongside ROKS Munmu the Great of the Republic of Korea Navy. Exercising together in open water is how navies test interoperability, that is, the ability of ships from two different services to communicate, manoeuvre and act as one formation when needed.

Why it matters

The deployment is a working example of India's naval diplomacy. By sending a frontline warship to a partner's home port, the Indian Navy builds the habit of operating together and signals a shared interest in peace, stability and security across the Indo-Pacific. For India and the Republic of Korea, the exercise adds a maritime layer to a strategic partnership that has grown steadily. For the Indian Navy, it is one more step in a long practice of engaging friendly foreign navies through professional contact rather than words alone.

Why aspirants should note it

Questions on such deployments usually ask the name of the Indian ship, the port and country it visited, the partner navy's vessel and the region. Note also that Sahyadri is Indian built, a detail that examiners like to pair with the word indigenous.
