November 12: India’s fifth pan-India coastal defence exercise, Sea Vigil-26, is under way, with the Indian Navy coordinating a readiness assessment before a sea phase scheduled for November 18 and 19, the Ministry of Defence has announced.
Key highlights
- The overall exercise runs from November 11 to 19.
- The initial Coastal Defence and Security Readiness Evaluation lasts through November 17.
- The exercise covers India’s coastline and Exclusive Economic Zone.
- The current schedule should be distinguished from the first Sea Vigil, held in January 2019.
Two phases, one national assessment
The ministry’s November 11 statement says Sea Vigil-26 involves coastal states and Union Territories, fishing and coastal communities, and multiple maritime agencies. Participating assets include those of the Navy, Coast Guard, coastal security police and Customs.
The exercise is also a build-up to TROPEX, the Navy’s biennial theatre-level readiness exercise. The ministry describes the combined purpose as addressing coastal defence and wider maritime security. It has not published a final assessment of this year’s results in the announcement reviewed for this report.
Schedule at a glance
| Phase | Dates |

| Sea phase | November 18–19, 2026 |
| Overall exercise | November 11–19, 2026 |
What the first exercise tested
A Ministry of Defence account issued on January 23, 2019 records the conclusion of the first Sea Vigil. It described participation by more than 100 ships, aircraft and patrol boats across security agencies. In that edition, the phases included assessment of organisations and simulated seaborne attacks.
The historical account also described testing responses to ship hijacking and threats to offshore installations. These details explain the exercise’s origins. They must not be presented as a list of events already carried out during Sea Vigil-26, whose current phase schedule is different.
Why coordination is the central issue
Analysis: Coastal security involves more than a vessel detecting a threat. Information must move between agencies, responsibilities must be understood and an appropriate response must follow. An exercise can expose weaknesses in that chain under controlled conditions, while an announcement that an exercise has begun cannot establish how well the chain performed.
For readers, the practical distinction is between a readiness drill and a security incident. Sea Vigil’s scheduled activity is not, by itself, evidence of an ongoing attack or a new emergency. Any claim of a real incident requires separate verification.
What to watch
The next official milestones are completion of the evaluation phase, the two-day sea phase and any subsequent findings released by participating agencies. Operational details may be limited, so conclusions about success should follow evidence rather than the exercise’s launch.
