Which edition of the pan-India coastal defence exercise Sea Vigil is being held in November 2026?
- A.Third
- B.Fourth
- C.Fifth
- D.Seventh
Correct answer
Explanation
The correct answer is the fifth edition. Sea Vigil-26 is the fifth edition of the pan-India coastal defence exercise and is being held from 11 to 19 November 2026 with the Indian Navy acting as the lead coordinating agency. The exercise is divided into the Coastal Defence and Security Readiness Evaluation phase, which runs from 11 to 17 November, followed by the Sea Phase on 18 and 19 November. Options A, B and D are therefore incorrect, since the edition number is neither the third nor the fourth nor the seventh. A candidate should also remember the origin of the exercise, because questions are often framed around it: Sea Vigil was conceptualised in 2018 to validate the measures instituted to strengthen maritime security in the aftermath of the 26/11 terror attacks on Mumbai. The exercise spans the entire coastline and Exclusive Economic Zone of the country and involves every coastal State and Union Territory along with fishing and coastal communities.
