The Indian Navy’s Sail Training Ship, INS Sudarshini, achieved its first-ever trans-Atlantic crossing when it docked at Antigua on 27 May 2026. This historic crossing forms a key part of the ten-month-long Lokayan 26 global maritime expedition. The ship departed from Kochi on 20 January 2026 and completed a challenging 19-day, nonstop voyage under sail from Mindelo, Cape Verde, to the Caribbean nation of Antigua and Barbuda. This leg pushed the ship’s total distance past 10,000 nautical miles for this deployment. The voyage demonstrates traditional naval navigation, builds maritime bridges across continents, and highlights India’s seafaring heritage on the world stage.
Technical and Structural Profile of the Vessel
Design and Construction
INS Sudarshini is an indigenously developed steel-hulled vessel designed by British naval architect Colin Mudie. Built by Goa Shipyard Limited for worldwide operations, the ship serves as a basic seamanship and character-building platform for naval trainees. It was commissioned into the Southern Naval Command of the Indian Navy on 27 January 2012.
Rigid Rigging Specifications
The vessel is designed as a three-masted barque. This configuration incorporates square rigging on the forward and main masts, alongside a fore-and-aft layout on the rear mizzen mast.

The Lokayan 26 Expedition
Scope and Operational Route
Lokayan 26 is a long-range transoceanic sailing campaign planned to span ten months. The journey covers nearly 22,000 nautical miles, mapping out port calls at 18 distinct harbors across 13 countries. The overall mission itinerary bridges major stops across West Asia, the Mediterranean region, Europe, Africa, the Caribbean, and North America.
Core Geopolitical Objectives
- Naval Training Excellence: The mission provides Indian Navy and Indian Coast Guard officer cadets firsthand exposure to the raw elements of open ocean navigation without relying entirely on modern automated systems. Trainees develop crucial skills in wind synchronization, sustained watchkeeping, and traditional sail-handling maneuvers.
- Strategic Maritime Outreach: The deployment projects naval diplomacy under the guiding philosophy of Vasudhaiva Kutumbakam (The World is One Family).
- International Event Participation: The route includes scheduled appearances at global maritime gatherings, such as the Escale à Sète festival in France and the upcoming SAIL 250 international parade of sails in New York, USA.
Historical Context of Ocean Crossings
Sailing across the Atlantic Ocean is a rare milestone for the Indian Navy’s sail training fleet. The last time an Indian Navy sail training ship completed an Atlantic crossing was nineteen years ago, when the first-in-class vessel INS Tarangini crossed the ocean during its 2007 deployment.
Institutional Framework and Maritime Philosophy
Southern Naval Command Base
INS Sudarshini operates under the administrative authority of the Southern Naval Command based in Kochi, Kerala. This specific command functions as the primary training hub for the entire Indian Navy infrastructure.
Linkage with the MAHASAGAR Doctrine
The long-range expedition directly supports the institutional vision of MAHASAGAR, an acronym for Maritime Security and Growth for All in the Region. This framework serves as the Indian Navy’s official collective outreach mechanism for active security dialogue and holistic cooperation with friendly littoral nations across the Indian Ocean Region and adjacent maritime zones.
