EXERCISE KONKAN-26 CONCLUDES OFF PLYMOUTH, UK

1. At a Glance

• KONKAN is the bilateral maritime exercise between the Indian Navy and the UK's Royal Navy. The 2026 edition, KONKAN-26, ended off Plymouth, UK on 15 Oct 2026 [1].
• Editions alternate in style. KONKAN-25 was a large carrier group exercise off India's western coast [2]. KONKAN-26 was a two-frigate exercise in UK waters, run by the Royal Navy's training authority FOST [1].
• UPSC relevance: India-UK defence ties, naval interoperability, anti-submarine warfare (ASW) capability and India's maritime outreach beyond the Indian Ocean. Exercise names, ships and locations are standard Prelims material.

2. Why in the News

• The Ministry of Defence (PIB) announced on 17 Oct 2026 that KONKAN-26 had concluded off Plymouth, UK [1].
• The exercise ran from 08–15 Oct 2026. Its Sea Phase ran 12–15 Oct 2026 (four days) [1].
• Ships: the Indian stealth frigate INS Trishul and the British HMS Sutherland, a Duke-class anti-submarine warfare frigate [1].

3. Background & Evolution

• Origin: No whitelisted (Tier 1/2) source I found gives the inception year. Non-whitelisted media say the series dates from 2004. Treat that as unverified.
• Key milestones (verified):
• 05 Oct 2025: KONKAN-2025 began on India's western coast. It ran in two phases, 05–12 Oct 2025 [2].
• KONKAN-2025 forces: India fielded the carrier battle group of INS Vikrant, with other surface, sub-surface and air units. The UK fielded its Carrier Strike Group led by HMS Prince of Wales, which included assets from Norway and Japan [2].
• KONKAN-2025 sea phase: anti-air, anti-surface and anti-submarine exercises, flying operations and seamanship evolutions [2].
• 14 Oct 2025: the UK Carrier Strike Group held a one-day exercise with the Indian Air Force off India's western coast [2].
• A later PIB backgrounder on INS Vikrant says KONKAN was conducted off Mumbai [3].

• 08–15 Oct 2026: KONKAN-26 was held in UK waters off Plymouth, run by FOST [1].

• Pattern: the venue alternates between Indian and UK waters. The scale also changes, from carrier groups in 2025 [2] to single frigates in 2026 [1].

• KONKAN-26 sea-phase serials [1]:
• advanced seamanship manoeuvres
• joint tactical exercises
• communication procedures
• anti-surface asymmetric warfare
• anti-submarine warfare

• weapon firings in a multi-threat maritime environment

• Stated outcomes: better interoperability, exchange of professional expertise and "Best Practices", and the ability to operate together "across complex maritime scenarios" [1].

5. Multi-Dimensional Analysis

Geopolitical / Strategic

• Holding the exercise in UK waters extends the Indian Navy's operational reach beyond the Indian Ocean [1].
• KONKAN-25 brought in Norwegian and Japanese assets through the UK Carrier Strike Group [2]. This shows the bilateral format can absorb a wider coalition (a minilateral pattern).
• PIB calls the relationship an "enduring maritime partnership between India and the UK" [1].

Military / Operational

• ASW focus: the UK sent a dedicated ASW frigate [1], and the serials included ASW and weapon firings [1]. Submarine threats in contested seas make this skill important.
• Anti-surface asymmetric warfare [1] means countering small, fast or unconventional threats such as swarm boats. Grey-zone and piracy scenarios make this relevant.
• Carrier-group interoperability in 2025 [2] marks a step up from frigate-level drills.

Scientific / Technological

• INS Vikrant is India's first indigenous aircraft carrier. Fielding it in KONKAN-25 showcased self-reliance (Aatmanirbharta) in naval building [3].
• The 2026 Indian unit is a stealth frigate [1], a platform designed for a low radar signature.

Administrative / Training

• FOST, the Royal Navy's operational sea-training authority, ran the exercise [1]. That gave the Indian ship a structured, standards-based evaluation rather than a purely joint manoeuvre.
• The exercise followed a harbour/shore period, then a sea phase. In 2025 there were two formal phases [2]. In 2026 the sea phase was the last four days of the eight-day window [1].

• KONKAN-26 concluded off Plymouth, UK on 15 Oct 2026 [1].
• KONKAN-26 ran 08–15 Oct 2026, with a four-day Sea Phase from 12–15 Oct 2026 [1].

8. What a Four-Day, Two-Ship Drill Can and Cannot Prove

• The exercise became much smaller in one year
• KONKAN-25 brought two aircraft carriers together, each with escort ships, submarines and aircraft [2].
• KONKAN-26 had one frigate from each side and a sea phase of only four days [1].

• So KONKAN-26 cannot test the big skill: running a whole fleet together with another navy. It tests how two single ships work together.

• The claimed results come only from the government

• The result PIB claims is better interoperability: the ability of two navies to talk, move and fight together using shared signals and procedures [1].
• No marks, test results or independent review have been published. The only record is the Ministry of Defence's own press release [1].

• In Mains, write that the exercise aimed to improve interoperability. Do not write that it proved it.

• The FOST format is the real gain, and it cuts both ways

• FOST, the Royal Navy's sea-training authority, ran the exercise [1]. So the Indian ship was tested against Royal Navy training standards.
• That gives the Indian crew outside feedback that a normal friendly drill does not give.
• The same fact also means the UK set the standard and judged the result. India learns the UK's procedures, but does not write them.

9. Why Hunting Submarines Abroad Does Not Fill India's ASW Gaps

• The drill trains people. It does not add ships or aircraft.
• KONKAN-26 practised anti-submarine warfare (ASW: finding and attacking enemy submarines) and weapon firings [1].

• Skill helps, but ASW also needs enough sensors, ships and aircraft to search a large area of sea.

• India's own submarine-hunting boats for coastal waters are arriving slowly

• The Navy plans 16 ASW Shallow Water Craft (ASW-SWC): small ships built to find submarines in littoral waters (shallow sea close to the coast) [6].
• The Ministry of Defence gave GRSE a ₹6,311 crore contract for eight of them in 2019, with 84 months to finish [7].
• The first one, INS Arnala, was commissioned (formally taken into service) only in June 2025 [8].

• The third Mahe-class craft, INS Mangrol, was commissioned on 12 Oct 2026, the same day KONKAN-26's sea phase began [9][1].

• Bigger programmes show the same delays

• Under Project-75, six submarines were due by December 2017. The last one was commissioned only in January 2025, after several extensions [10].
• The Navy is also short of planes and helicopters for reconnaissance (searching the sea) and transport [10].
• A foreign exercise cannot cover these gaps. Only ships and aircraft that are built and delivered on time can do that.

10. Is Sending a Frigate to Plymouth the Best Use of a Scarce Ship?

• The strongest objection
• Parliament's Standing Committee on Defence says the Navy's main threats are China and Pakistan, plus piracy and drug trafficking. All of these are in or near the Indian Ocean [10].
• The money is short. For 2021–26, the Ministry expected ₹9.01 lakh crore for capital outlay (money for new equipment), against a plan that needed ₹17.46 lakh crore. That is a 48% shortfall [10].

• The objection follows: while ships are this scarce, a frigate spending weeks in the North Atlantic is a frigate not patrolling the Indian Ocean.

• What is right about the objection

• The cost is real. PIB gives no figure for fuel, crew time or days away from Indian waters [1].

• With 65 ships and submarines still under construction [10], every ship already in service is in high demand.

• Why the exercise is still defensible

• Visits go both ways. In 2025 the UK sent its whole Carrier Strike Group to India's western coast [2]. A small Indian visit in return keeps the arrangement balanced, at a fraction of that cost.
• Under FOST, India gets structured training against Royal Navy standards at the UK's expense [1]. Building that kind of training at home would take years.
• The useful question for Mains is not 'Should India exercise abroad?' but 'How often, and at what cost to Indian Ocean patrols?'. Give that balanced answer.

11. What Would Make KONKAN Matter Beyond One Week of Drills

• Exercises signal friendship. Shared technology lasts longer.
• In November 2024, the two defence ministries signed a Statement of Intent to co-design and co-produce electric propulsion (electric engines) for future Indian naval ships [5].
• By October 2025, the two Prime Ministers had only stated an 'intent to finalise' an Inter-Governmental Agreement (IGA: a binding government-to-government deal) on this [4].

• Action: The Ministry of Defence should sign this IGA. It would turn a promise into a project with deadlines.

• Link the exercises to the Indian Ocean framework India already leads

• Both countries agreed to set up a Regional Maritime Security Centre of Excellence (RMSCE) under IPOI [4]. IPOI is the Indo-Pacific Oceans' Initiative, India's framework for maritime cooperation in the region.

• Action: Future KONKAN editions could include serials on piracy, drug trafficking and disaster relief. These are the 'non-traditional' threats the RMSCE is meant to handle [4][10].

• Use the review mechanism that already exists

• India-UK Vision 2035 is reviewed every year by India's External Affairs Minister and the UK Foreign Secretary [4].
• The KONKAN-25 release presented that exercise as an example of the Comprehensive Strategic Partnership under Vision 2035 [2].
• Action: The annual review should report what each KONKAN edition changed, such as shared procedures adopted or training gaps closed. Then success can be measured, not just announced.

12. Anchors for Answers

• Data: 65 ships and submarines under construction for the Indian Navy [10]; 48% shortfall in capital outlay, 2021–26 (₹9.01 lakh crore expected against ₹17.46 lakh crore projected) [10]; 16 ASW Shallow Water Craft planned [6]
• Report/Committee: Standing Committee on Defence (2023): asked that planned naval procurements be completed on schedule to boost India's presence in the Indian Ocean Region [10]
• Comparison: KONKAN-25 (two carrier groups, off India) vs KONKAN-26 (two frigates, four-day sea phase, off Plymouth): use it to separate a big strategic signal from a small training exercise [1][2]
• Scheme: IPOI: India-UK commitment to set up a Regional Maritime Security Centre of Excellence [4]; indigenous ASW-SWC programme (INS Arnala, INS Mangrol), India's own answer to the coastal submarine threat [6][9]
• Framework: India-UK Vision 2035, reviewed every year by India's External Affairs Minister and the UK Foreign Secretary; India-UK Statement of Intent on naval electric propulsion (Nov 2024) [4][5]

13. Mains Relevance

• GS-II: International Relations. Syllabus headings: "Bilateral, regional and global groupings and agreements involving India"; "Effect of policies and politics of developed countries on India's interests."
• GS-III: Security. Syllabus heading: "Security challenges and their management", which covers maritime security and defence technology and indigenisation (INS Vikrant).
• Question stems: 1. Bilateral naval exercises have moved from goodwill gestures to instruments of interoperability and strategic signalling. Examine with reference to India's exercises with European navies. 2. Discuss the strategic significance of the Indian Navy operating in extra-regional waters such as the North Atlantic. What capability gaps does it reveal or address? 3. Anti-submarine warfare is emerging as the decisive naval competency in the Indian Ocean. Evaluate India's preparedness and the role of foreign partnerships.

15. NCERT Concepts to Revise

• Signalling (Economy): The note argues exercises are strategic signals of partnership, and Mains answers must separate signal from real capability.
• Indian Ocean (Geography): The Navy's main threats and patrols are in the Indian Ocean; exercising in the North Atlantic extends reach beyond it.
• Self-reliance (Economy): INS Vikrant and the indigenous anti-submarine craft show India's push to build warships at home instead of importing.
• Standing committee (Polity): The Standing Committee on Defence report supplies the note's data on naval threats, delays and funding shortfalls.
• Radar (Geography): A stealth frigate like INS Trishul is built to have a low radar signature, so it is hard to detect.

16. Common Errors / Trap Areas

• Location: KONKAN-26 was held off Plymouth, UK [1], not on India's Konkan coast. The name does not fix the venue. KONKAN-25 was off India's western coast [2].
• KONKAN vs Konkan Shakti: KONKAN is a bilateral naval exercise. Konkan Shakti is the tri-service variant. Don't mix them up.
• Mixing up the ships: Trishul with Sutherland (2026) [1]; Vikrant with Prince of Wales (2025) [2]. Don't swap the editions.
• Ship class: "Duke-class" describes HMS Sutherland (the British frigate) [1], not the Indian ship. INS Trishul is generally listed as a Talwar-class frigate; that is general knowledge, not confirmed by the whitelisted sources here.
• Participants: Norway and Japan contributed assets to the UK Carrier Strike Group in 2025 [2]. That does not make KONKAN a multilateral exercise. It remains India-UK bilateral.
