Exercise KONKAN-26: India-UK Annual Bilateral Naval Exercise at Plymouth with INS Trishul

Why in News

Exercise KONKAN-26, the annual bilateral maritime exercise between the Indian Navy and the United Kingdom's Royal Navy, is being conducted off the coast of Plymouth, England, from October 8–15, 2026. India's guided-missile stealth frigate INS Trishul arrived at Plymouth to participate in professional exchanges during the harbour phase and tactical manoeuvres during the sea phase. The exercise is the latest iteration of an over two-decade-old bilateral naval partnership and takes place within the framework of the India-UK Comprehensive Strategic Partnership and the India-UK Vision 2035.

Background

Exercise KONKAN is an annual bilateral maritime exercise that was first instituted in 2004, making the 2026 edition one of its early twenties iterations. The exercise alternates each year between Indian and UK hosting, and the 2026 edition is hosted by the United Kingdom at Plymouth — the UK's principal naval base and home to HMS Devonport, the largest naval base in Western Europe.

The broader India-UK defence relationship was significantly elevated with the signing of the India-UK Defence and International Security Partnership (DISP) in 2015, and further strengthened through the India-UK Roadmap 2030 (signed by PM Narendra Modi and UK PM Boris Johnson in May 2021, later extended to the Vision 2035). Defence cooperation, including maritime security, is one of the five pillars of the Roadmap alongside trade, climate, health, and people-to-people ties.

Current Developments

Exercise Structure

KONKAN-26 is conducted in two phases:

1. Harbour Phase (Plymouth Port): Professional interactions between officers and sailors of both navies; cross-deck visits allowing personnel to tour each other's vessels; sports fixtures; cultural engagements; and the ship being open to visitors from the public.
2. Sea Phase (off Plymouth coast): Tactical manoeuvres including anti-submarine warfare (ASW) drills, surface warfare exercises, maritime interdiction operations (MIO), Visit Board Search and Seizure (VBSS), damage control exercises, and communication protocol standardisation.

Indian Participant

INS Trishul is a Talwar-class guided-missile stealth frigate of the Indian Navy. Key specifications:

• Class: Talwar-class (Project 1135.6) — built in Russia for the Indian Navy
• Armament: Brahmos supersonic cruise missile, Shtil-1 surface-to-air missiles, Torpedo tubes, 100mm deck gun
• Displacement: ~4,000 tonnes
• Role: Multi-role — anti-surface, anti-submarine, anti-air warfare
• Commissioned: June 2003 (Western Naval Command, Mumbai)

Significance of the 2026 Edition

KONKAN-26 holds particular significance in the context of:

• India-UK Free Trade Agreement (FTA) negotiations — resumed in 2024, with both sides targeting conclusion by mid-2027.
• UK's post-Brexit "Global Britain" policy tilt towards the Indo-Pacific, including increased Royal Navy presence in the region (HMS Queen Elizabeth Carrier Strike Group's 2021 Indo-Pacific deployment was a landmark).
• India's growing importance in the QUAD framework and Indo-Pacific maritime security architecture.

Constitutional Provisions

Article 53(2) vests the supreme command of the Defence Forces in the President. Article 312 relates to All India Services and is relevant to the Indian Foreign Service which manages diplomatic dimensions of such bilateral exercises. The Union List (Seventh Schedule, List I, Entry 1) gives Parliament exclusive power over "Defence of India and every part thereof including preparation for defence and all such acts as may be conducive in times of war to its prosecution." Bilateral military exercises fall within this exclusive Union domain.

Legal Framework

• United Nations Convention on the Law of the Sea (UNCLOS), 1982: India and UK are both signatories. UNCLOS provides the legal framework for maritime exercises in international waters, including innocent passage, exclusive economic zones (EEZs), and freedom of navigation.
• Bilateral Status of Forces Agreements (SOFA): Govern legal status of military personnel of one country during exercises in another's territory/waters.
• India-UK Defence and International Security Partnership (DISP), 2015: Provides the strategic framework for defence cooperation including joint exercises.

Institutional Framework

• Indian Navy: Tri-service defence force; Chief of Naval Staff heads it. Western Naval Command (Mumbai) oversees western maritime operations and bilateral exercises with Western partners.
• Royal Navy (UK): One of NATO's two largest navies. Headquarters at Portsmouth; operational base at Plymouth (HMS Devonport).
• Ministry of Defence (MoD), India: Nodal ministry for defence cooperation; oversees all bilateral defence exercises.
• India-UK Joint Working Group on Defence: The bilateral mechanism under which KONKAN is institutionalised and annual planning occurs.

Economic Dimensions

Maritime security directly supports global trade — approximately 90% of world trade by volume and 80% by value is carried by sea. India's Exclusive Economic Zone (EEZ) of 2.37 million sq km is among the world's largest. Ensuring freedom of navigation and suppressing piracy, smuggling, and human trafficking in the Indian Ocean Region (IOR) has direct economic value for India's trade, which amounted to over $1.4 trillion in FY26. Defence partnerships like KONKAN enhance India's capacity to police its maritime domain and protect undersea cable and pipeline infrastructure.

Environmental Dimensions

Modern naval exercises increasingly integrate environmental considerations — both navies follow protocols to minimise underwater noise pollution (which harms cetaceans including whales and dolphins) during exercises. The India-UK defence partnership also includes a marine environment component under the broader climate and sustainability pillar of the India-UK Roadmap 2030/Vision 2035.

International Relations

KONKAN-26 is one element of a broader network of India's bilateral and multilateral naval exercises that signal India's role as a net security provider in the Indo-Pacific:

• MALABAR: India-USA-Japan (and Australia since 2020) — QUAD's maritime dimension.
• TASMAN SABER: India-Australia.
• VARUNA: India-France.
• TALON SABER / SHAKTI: India-USA (army).
• KONKAN: India-UK.
• INDRA: India-Russia.

The UK's increased Indo-Pacific naval presence post-Brexit aligns well with India's ambition to build a rules-based maritime order. The 2021 deployment of the HMS Queen Elizabeth Carrier Strike Group through the Indian Ocean and its joint exercise with the Indian Navy signalled a step-change in bilateral maritime cooperation.

Internal Security Dimensions

Interoperability gained through KONKAN exercises directly enhances India's ability to conduct joint operations against non-traditional maritime threats: piracy (Gulf of Aden/Somali coast), narco-trafficking (heroin from Afghanistan transiting through the Arabian Sea), human smuggling, and IED/terrorism threats targeting India's maritime trade routes. India's Marine Commandos (MARCOS) also conduct VBSS training during such exercises.

Challenges

• UK's post-Brexit geopolitical uncertainty and defence budget constraints limit the scale of naval deployments it can sustain in the Indo-Pacific.
• India's strategic autonomy doctrine creates limits on the depth of interoperability India is willing to achieve with any single partner, including the UK.
• China's growing naval presence in the Indian Ocean (including submarine deployments and Djibouti base) increases the strategic stakes of India-UK maritime cooperation.

Government Initiatives

• India-UK Vision 2035: Successor to the India-UK Roadmap 2030; sets out a comprehensive bilateral partnership framework with defence as a core pillar.
• SAGAR (Security and Growth for All in the Region): India's overarching Indian Ocean strategy articulated by PM Modi since 2015 — frames India as a security provider in the IOR.
• Mission SHAKTI (maritime domain awareness): India's initiative for white shipping information sharing with partner navies.
• Project 17A (Nilgiri-class frigates): India's indigenously built next-generation frigates — the future of bilateral exercises with the UK.

Way Forward

• Conclusion of the India-UK Free Trade Agreement (targeted by mid-2027) will reinforce strategic and economic pillars of the bilateral relationship.
• QUAD and I2U2 frameworks create complementary multilateral structures within which bilateral exercises like KONKAN can be nested for greater collective security impact.
• Parliamentary Standing Committee on Defence has recommended enhancing the pace of defence co-production and technology transfer with QUAD and Five Eyes partners, including the UK.
