The India-UK bilateral maritime exercise Konkan-26 has concluded off Plymouth, United Kingdom, with the Indian Navy and the Royal Navy completing a broad range of professional and operational serials, the Indian Navy confirmed on Saturday, 17 October 2026. The exercise, held from 8 to 15 October, marked another chapter in over two decades of structured naval cooperation between the two countries.

Ships and Command Structure

The Indian Navy was represented by INS Trishul, a guided missile stealth frigate, which arrived at Plymouth on 11 October. The Royal Navy deployed HMS Sutherland, a Duke-class anti-submarine warfare frigate. The exercise was conducted under the aegis of the Royal Navy's Fleet Operational Standards and Training (FOST), one of the most demanding naval training frameworks in the world.

Key Operational Serials

The intensive four-day Sea Phase, conducted from 12 to 15 October, was the centrepiece of the exercise. According to an Indian Navy statement, serials included 'advanced seamanship manoeuvres, joint tactical exercises, communication procedures, anti-surface asymmetric warfare, anti-submarine warfare and weapon firings in a multi-threat maritime environment.' The Navy noted that these serials 'enhanced interoperability between the participating units.'

Notably, anti-submarine warfare featured prominently — a domain of growing strategic importance as both India and the UK deepen their focus on undersea competition in the Indo-Pacific and the North Atlantic respectively.

Strategic Significance

The Ministry of Defence described Konkan-26 as 'a testament to the enduring maritime partnership between India and the UK,' adding that the exercise has 'grown significantly in scale and complexity' since its inception. The ministry also framed the exercise within the India-UK Vision 2035 Comprehensive Strategic Partnership, characterising it as a 'reaffirmation of the shared commitment to ensuring secure, open and free seas.'

This comes amid broader India-UK diplomatic momentum, with both nations working toward a long-pending bilateral trade agreement and strengthening security ties across maritime, cyber, and defence domains.

Two Decades of Konkan

The Konkan series has been a cornerstone of India-UK naval engagement for over 20 years. What began as a relatively modest bilateral drill has evolved into a complex, multi-domain exercise encompassing surface warfare, subsurface operations, and joint communications. Each iteration has progressively raised the bar on interoperability — a quality that takes on heightened relevance as both navies operate in contested maritime environments across different theatres.

With Konkan-26 now complete, attention will turn to how the lessons from Plymouth feed into broader joint frameworks, including potential participation in multilateral naval exercises where both India and the UK are active stakeholders.
