What happened

For Prelims

For UPSC: Sea Vigil-26 (fifth edition), 11-19 November 2026, Navy lead: CDSRE 11-17 November, Sea Phase 18-19 November; started 2018 after 26/11; build-up to biennial TROPEX.
What it is NOT: The release gives no scenario details, no count of ships, aircraft, boats or personnel, and no cost. It does not say how many Coastal States, Union Territories or fishing boats are actually taking part, or what findings from the four earlier editions led to changes; the years of those editions are not stated. It does not say whether the lessons will be published or who will certify the results, and nothing is said about cyber, port-security or offshore-installation scenarios.

For Mains

Syllabus: GS3.20 · GS3.19 · Linkage L1

Anchor
Maritime security in India is shared among the Navy, Coast Guard, State marine police, Customs and port authorities. A single drill across all of them tests the hand-offs, which is where gaps tend to appear.
Substantiation (data)
Sea Vigil-26 runs 11 to 19 November 2026 across the whole coastline and EEZ, with all Coastal States and Union Territories, five facilitating ministries and a seven-day readiness evaluation before the two-day sea phase.
Position
Including fishing and coastal communities treats them as sensors, not suspects. The link to TROPEX connects coastal defence with fleet operations on the high seas.
Counterpoint
A drill proves readiness only if scenarios are hard and findings are acted on. The release names no scenarios, force levels or lessons from four earlier editions, and a fixed exercise window can be rehearsed.
Way forward
Publish a yearly summary of gaps found and fixed, add cyber and port-security scenarios, test fishing-boat tracking and registration, run surprise drills outside the window, and review Coastal Security Police capacity.
Conclusion
The exercise checks coordination more than hardware. Its value depends on what changes after the sea phase ends on 19 November.
