INS SAHYADRI ARRIVES AT BUSAN, REPUBLIC OF KOREA, FOR INDIA-RoKN BILATERAL EXERCISE

1. At a Glance

• INS Sahyadri is an indigenously designed and built guided missile stealth frigate. It reached Busan, Republic of Korea (ROK) for the IN–RoKN Bilateral Exercise [1].
• This is naval diplomacy: the exercise aims at interoperability and at "enduring partnerships with friendly foreign navies", not at forming an alliance [1].
• It is the operational, maritime side of the India–ROK Special Strategic Partnership: Strategic Partnership in 2010, upgraded to Special Strategic Partnership in 2015 [2].
• For UPSC it links to GS-II (bilateral relations, Indo-Pacific) and GS-III (defence indigenisation), and to Prelims questions on exercise names and partners.

2. Why in the News

• INS Sahyadri arrived at Busan Naval Harbour on 26 Oct 2026 for the IN–RoKN Bilateral Exercise. The press release was posted on 28 Oct 2026 [1].
• The sea phase partner is ROKS Munmu the Great [1].
• It follows the inaugural India–ROK bilateral naval exercise, held 13–16 Oct 2025 in ROK, which also involved INS Sahyadri [2]. The 2026 release itself does not number the edition, so "2nd edition" is an inference.

3. Background & Evolution

• Consular relations: 1962. Diplomatic relations: 10 Dec 1973 [2].
• Korean War role: India sent the 60th Parachute Field Ambulance (627 personnel, Lt Col A.G. Rangaraj), which treated about 220,000 patients. A ceasefire on 27 Jul 1953 followed an India-sponsored UN resolution. Lt Gen K.S. Thimayya chaired the Neutral Nations Repatriation Commission (NNRC) [2].
• 2010: Strategic Partnership. May 2015: upgraded to Special Strategic Partnership during PM Modi's state visit to Seoul [2].
• Sep 2020: Roadmap for Defence Industries Cooperation signed [2].
• Apr 2023: Navy Staff Talks held in India [2].
• 2023: 50 years of diplomatic ties marked [2].
• 13–16 Oct 2025: inaugural bilateral naval exercise in ROK between INS Sahyadri and ROKS Nojeokbong (as named by MEA) [2].
• Feb 2026: ROK destroyer Gang Gam-chan took part in IFR-2026 and MILAN-2026 at Visakhapatnam (17–26 Feb). A RoKN delegation attended the 9th IONS Chiefs' Conclave [2].
• Oct 2026: INS Sahyadri at Busan for the next exercise, with ROKS Munmu the Great [1].

5. Multi-Dimensional Analysis

Geopolitical / Strategic

• Practical cooperation under the Special Strategic Partnership. The 2026 State Visit adopted a Joint Strategic Vision 2026–2030 [2].
• In April 2026, ROK joined the Indo-Pacific Oceans Initiative (IPOI), which aligns the two countries on maritime security [1][2].
• ROK's participation in MILAN-2026, IFR-2026 and IONS brings a major East Asian navy into India's IOR-centred multilateral platforms [2].
• The exercise widens India's Act East presence beyond ASEAN into Northeast Asia and diversifies its partners beyond the Quad.

Defence-industrial / Technological

• Sahyadri is an example of indigenous shipbuilding under Aatmanirbhar Bharat [1].
• A contract for 100 more K9 Vajra guns was signed on 4 Apr 2025 between Hanwha Aerospace and L&T [2].
• Defence-industry joint-venture MoUs were signed at Aero India (Feb 2025), on 5 Dec 2025, and at the Defence Industry Round Table in Seoul (20 May 2026) [2].

Economic / Maritime

• VOYAGES, the Comprehensive Framework for Partnership in Shipbuilding, Shipping and Maritime Logistics, was adopted in April 2026 [2].
• Target: raise trade from about USD 25 bn to USD 50 bn by 2030 [2].

Administrative / Operational

• Interoperability is built in two layers: harbour (people and procedures) and sea (coordination between ships) [1].
• Institutional base: biennial staff talks, regular ship visits, and coast guard links. The two coast guards signed a Maritime Search & Rescue MoU in July 2025, and the Korea Coast Guard joined NATPOLREX-10 in October 2025 [2].

Historical / Soft power

• Shared memory of the Korean War. RM Rajnath Singh inaugurated the first Indian War Memorial at Imjingak Peace Park, Paju on 21 May 2026 [2].

8. Why One Year Does Not Yet Make a Habit

• The exercise has no fixed name or cycle yet
• The 2026 press release does not say which edition this is [1].
• The first edition was held only in October 2025 [2]. So two meetings, one year apart, are all the record we have.

• Without an agreed name and a fixed schedule, each edition depends on whether a ship happens to be free and nearby. A one-time visit can quietly stop the next year.

• Even the official record is not consistent

• MEA names ROKS Nojeokbong as the Korean partner in 2025 [2]. A mirrored copy of the PIB release names a different ship, as the note already flags.

• Records disagree on a basic fact. That is what happens when an activity has not yet become a regular, written-down routine.

• India sent the same single frigate both times

• INS Sahyadri took part in 2025 and again in 2026 [1][2].
• One ship can practise only a few skills. It can do coordinated manoeuvres and communication drills. It cannot train for task-group operations, meaning several ships working together, such as anti-submarine screening.
• Interoperability (the ability of two navies to work together smoothly at sea) grows only as fast as the exercise grows in size and difficulty.

9. Is One Frigate a Year Just a Photo Opportunity?

• The strongest objection
• Much of the programme happens in harbour: cross-deck visits, sports and calls on senior officers [1].
• The two navies also face different main threats. India's navy is centred on the Indian Ocean. The RoKN is far away in Northeast Asia.

• So a critic can say the exercise is mostly ceremony, with very little real military value.

• What is right about this objection

• A single ship, a few days at sea, and a stated aim of "partnership" [1] will not make the two navies able to fight together.

• The release lists no complex drills. It says only "coordinated maritime activities" [1].

• Why it still matters

• The exercise is one part of a chain that is getting thicker. Korea sent a destroyer to MILAN and IFR-2026, attended IONS, and joined IPOI [2].
• The two coast guards already have a Search & Rescue MoU [2]. Their 13th high-level meeting was held in New Delhi [7]. So there are working-level links beyond ceremony.

• Naval diplomacy is supposed to start small. Its value is the habit of contact, as long as that habit then grows into harder drills.

• Fair conclusion: today it is mostly a signal. It becomes a real capability only if its size and difficulty grow.

10. Many Shipbuilding MoUs, No Warship Yet

• The naval shipbuilding promise is old
• In 2017 the Cabinet Committee on Security (CCS) approved an inter-governmental MoU with ROK on defence industry cooperation in shipbuilding. It named Hindustan Shipyard Limited (HSL), Visakhapatnam as India's partner [3].

• None of the cited 2025–26 releases report a warship built or co-built under that MoU.

• The new energy has gone to commercial ships, not naval ones

• Under VOYAGES (2026), the main project is a greenfield shipyard (a new yard built from scratch) at Thoothukudi. HD KSOE, NSHIP-TN and SMFCL signed for a yard of 2.5 million GT (gross tonnage, a measure of a ship's size) capacity [5].

• This builds merchant-ship capacity. It does not by itself give the Indian Navy a Korean warship partner.

• The one real success is on land, not at sea

• The K9 Vajra gun (Hanwha–L&T) is the clearest example of co-production, meaning a foreign and an Indian firm building a weapon together in India [2].

• The 10th Joint Committee Meeting on Defence Industries and Logistics Cooperation (New Delhi, 29 Sep 2026) brought in Hanwha Aerospace, KAI, L&T and BEML [4]. These are mainly land and aerospace firms.

• Why this matters for the exercise

• Navies that use each other's ships, spares or repair yards become interoperable much faster than navies that only meet once a year.
• Right now the exercise and the defence-industry track run side by side but do not meet.

11. The Trade Gap Behind the Strategic Story

• India buys far more from Korea than it sells
• In 2024–25, India imported about USD 21 bn from ROK and exported about USD 5.8 bn [6].
• That is a trade deficit (imports greater than exports) of roughly USD 15 bn. The deficit is calculated here from MEA's figures.

• For calendar 2025, the note's figures (19.2 bn vs 6.4 bn) still show a gap of about USD 12.8 bn [2].

• CEPA grew trade but not balance

• Trade rose from USD 14.2 bn when CEPA started to USD 26.89 bn in 2024–25 [6].

• Growth went mostly to imports. So the USD 50 bn target for 2030 [2] could widen the gap if nothing else changes.

• The upgrade talks are where this gets decided

• CEPA working groups are discussing market access, rules of origin (rules on how much of a product must be made in the partner country to get the lower tax), SPS (food-safety and plant-health rules) and TBT (technical standards) [7].

• The April 2026 summit set the first half of 2027 as the target for finishing the upgrade [6]. Talks were restarted, which shows they had stalled earlier [6].

• Why a naval note should care

• Strategic warmth is easier to sustain when the economic relationship is seen as fair at home. A deficit that keeps growing gives critics in India a reason to doubt the "Special" in the partnership.

12. What Should Follow, and Who Must Do It

• Indian Navy and RoKN: give the exercise a name and a fixed cycle
• Fix a regular schedule and a formal name in the biennial Navy Staff Talks [2]. This stops the exercise depending on chance ship deployments.

• Step by step, add a second ship or a maritime patrol aircraft so drills can move beyond basic coordination.

• MoD: put naval items on the Joint Committee agenda

• The Joint Committee on Defence Industries and Logistics Cooperation [4] is the forum that already exists. It should add naval MRO (maintenance, repair and overhaul of ships) and spares.

• It should also revisit the 2017 HSL shipbuilding MoU [3] and either give it a project or close it honestly.

• Ministry of Ports, Shipping and Waterways: link VOYAGES to defence needs

• The Thoothukudi yard [5] could be planned with space for naval auxiliary vessels (support ships such as tankers), not only merchant ships.

• Ministry of Commerce: use the CEPA upgrade to address the deficit

• Push for market access for Indian goods and services, and for tighter rules of origin, in the talks due to finish by the first half of 2027 [6][7].

• Coast guards: build on the SAR MoU

• Joint search-and-rescue drills [2] are cheap and politically easy. They build working habits that the navies can later use.

13. Anchors for Answers

• Data: India–ROK trade 2024–25: imports ~USD 21 bn vs exports ~USD 5.8 bn, a deficit of roughly USD 15 bn; trade was USD 14.2 bn at CEPA start [6]
• Data: Thoothukudi greenfield shipyard under VOYAGES, 2.5 million GT capacity (HD KSOE–NSHIP-TN–SMFCL) [5]
• Report/Committee: 10th India–ROK Joint Committee Meeting on Defence Industries and Logistics Cooperation, New Delhi, 29 Sep 2026 [4]; Department of Commerce Annual Report 2024–25 on CEPA sub-groups [7]
• Law/Case: CCS-approved India–ROK MoU on Defence Industry Cooperation in Shipbuilding, 2017, with HSL as the Indian partner [3]
• Scheme: VOYAGES framework (2026), the bridge between Korean shipbuilding skill and Indian yards [5]; IPOI, which ROK joined in 2026 [2]

14. Mains Relevance

• GS-II: India and its neighbourhood / bilateral relations; groupings and agreements affecting India's interests (Indo-Pacific, IPOI).
• GS-III: Security challenges; defence indigenisation and technology.
• Possible questions: 1. Bilateral naval exercises are instruments of strategic signalling short of alliance. Examine with reference to India's maritime engagement with the Republic of Korea. 2. India–ROK ties are moving from an economic to a strategic-defence focus. Discuss in light of recent developments. (250 words) 3. Assess how defence-industrial cooperation with partners like South Korea can advance Aatmanirbhar Bharat in defence.

16. NCERT Concepts to Revise

• Trade deficit (Economy): India imports far more from Korea than it exports; the note analyses this gap and the CEPA upgrade talks.
• Rules of origin (Economy): The CEPA upgrade talks cover rules of origin, which decide which goods get lower tariffs and so affect the deficit.
• Comprehensive economic partnership agreement (Economy): CEPA (2010) is the economic pillar of India–ROK ties; its upgrade is due to finish by 2027.
• Korean War (History): India's medical unit and the NNRC role during this war form the historical base of India–ROK ties.
• Cabinet Committee on Security (Polity): The CCS approved the 2017 India–ROK shipbuilding MoU, which has produced no warship so far.
• Joint production (Economy): K9 Vajra, built by Hanwha and L&T in India, is the note's main example of defence co-production.

17. Common Errors / Trap Areas

• Wrong partner ship: MEA names ROKS Nojeokbong for the 2025 inaugural exercise [2]. The 2026 exercise uses ROKS Munmu the Great [1]. Do not mix up the two editions. A mirrored copy of the 2025 PIB release, which I could not cite under the source whitelist, names ROKS Gyeongnam. Expect sources to disagree on the 2025 partner.
• "First-ever" in 2026: the inaugural edition was in October 2025 [2], not 2026.
• Partnership years: Strategic (2010) vs Special Strategic (2015). CEPA was also implemented in 2010 [2].
• Bilateral vs multilateral: IN–RoKN is bilateral; MILAN and IFR are multilateral [1][2].
• Vessel type: INS Sahyadri is a frigate, not a destroyer or corvette [1]. Its often-cited class (Shivalik, third ship, commissioned 2012) does not appear in the sources used here. Check it against an official Navy or PIB page before relying on it.
