SLINEX-26: India-Sri Lanka Maritime Exercise Ends in Visakhapatnam
The 13th edition of the India-Sri Lanka bilateral naval exercise SLINEX-26 ended at Visakhapatnam on 21 September 2026 after a five-day harbour and sea run.

Why in News
The Ministry of Defence announced on 23 September 2026 that SLINEX-26, the 13th edition of the India-Sri Lanka bilateral maritime exercise, had concluded at Visakhapatnam after being conducted from 17 to 21 September 2026.
The 13th edition of SLINEX, the bilateral maritime exercise that the Indian Navy holds with the Sri Lanka Navy, was wrapped up at Visakhapatnam on 21 September 2026. The Ministry of Defence announced the closing on 23 September 2026. The two fleets had begun working together on 17 September, so the drill ran five days on the eastern seaboard, at the port that hosts the Eastern Naval Command.
How the exercise was built
Like most bilateral naval drills, SLINEX-26 was split into two stages. The harbour phase kept the ships alongside: officers and sailors of the two navies sat through subject discussions, went aboard each other's warships on cross-deck visits, and played sporting fixtures together. The point of this stage is familiarity, because crews that have met ashore work faster together at sea.
What the sea phase covered
- Manoeuvres in which the ships of both navies moved as one formation.
- Air operations flown alongside the surface units.
- Replenishment at sea carried out at night, one of the harder seamanship tasks a warship performs.
- Special Forces work, including slithering on to a deck from a helicopter.
- Visit, Board, Search and Seizure (VBSS) drills, the boarding routine used against piracy, smuggling and suspicious merchant traffic.
Why the drill matters
The Ministry places SLINEX inside two larger frames. The first is MAHASAGAR, India's vision for the maritime neighbourhood; the second is the Neighbourhood First policy, under which India builds capacity in partner navies rather than only training with them. Both point at the same aim, a safe and steady Indian Ocean Region, through which a very large share of India's trade and energy moves.
Points a student should hold on to
SLINEX is an India-Sri Lanka exercise, not a multilateral one, and it alternates between Indian and Sri Lankan ports. The word to attach to it in an answer is interoperability, the ability of two separate forces to operate as a single unit. Visakhapatnam, on the Bay of Bengal coast of Andhra Pradesh, is the harbour to remember for this edition.

Practice Questions
SLINEX-26, which concluded at Visakhapatnam, is a bilateral maritime exercise between India and which country?
- A.Bangladesh
- B.Sri Lanka
- C.Maldives
- D.Indonesia
Show answer
Correct answer: B. Sri Lanka
Explanation
The correct answer is Sri Lanka. SLINEX is the bilateral maritime exercise held between the Indian Navy and the Sri Lanka Navy, and its name itself is formed from the two countries. The 13th edition, SLINEX-26, was conducted from 17 to 21 September 2026 and concluded at Visakhapatnam, with a harbour phase of professional exchanges and cross-deck visits followed by a sea phase of coordinated manoeuvres, air operations, night replenishment at sea and Special Forces drills. Option A, Bangladesh, is wrong because the exercise India conducts with the Bangladesh Navy carries a different name and did not feature in this release. Option C, Maldives, is wrong for the same reason; no Maldivian participation was reported in this exercise. Option D, Indonesia, is wrong because the release describes SLINEX strictly as an India-Sri Lanka bilateral activity, with no third navy taking part. The Ministry of Defence connected the drill to the MAHASAGAR vision and the Neighbourhood First policy.
Which edition of SLINEX was held in September 2026?
- A.11th
- B.12th
- C.13th
- D.14th
Show answer
Correct answer: C. 13th
Explanation
The correct answer is 13th. The Ministry of Defence described the exercise held from 17 to 21 September 2026 as the 13th edition of the India-Sri Lanka bilateral maritime exercise, and it concluded at Visakhapatnam. Editions are the detail most often asked about recurring exercises, so the number should be memorised along with the venue and the year. Option A, the 11th, and option B, the 12th, refer to earlier editions of the series and not to the one that ended in September 2026. Option D, the 14th, would be a future edition and has not yet been held. The exercise ran in two phases: a harbour phase with cross-deck visits and sporting interaction, and a sea phase with coordinated manoeuvres, air operations, night replenishment at sea, slithering operations and Visit, Board, Search and Seizure drills that build interoperability between the two navies.
In the context of SLINEX-26, what does the abbreviation VBSS stand for?
- A.Visit, Board, Search and Seizure
- B.Vessel Berthing and Safety Standards
- C.Visual Beacon Signalling System
- D.Vertical Boarding and Sea Survey
Show answer
Correct answer: A. Visit, Board, Search and Seizure
Explanation
The correct answer is Visit, Board, Search and Seizure. The release lists VBSS among the Special Forces drills carried out in the sea phase of SLINEX-26, along with slithering operations. VBSS is the standard boarding procedure by which a naval team stops a suspicious vessel, goes aboard, searches it and, where the law allows, seizes it, and it is the core skill in anti-piracy and anti-smuggling operations in the Indian Ocean Region. Option B, Vessel Berthing and Safety Standards, is invented and describes harbour regulation rather than a naval drill. Option C, Visual Beacon Signalling System, is a made-up equipment name and not a Special Forces activity. Option D, Vertical Boarding and Sea Survey, mixes two unrelated ideas and does not appear in the release. The sea phase also covered coordinated manoeuvres, air operations and replenishment at sea carried out at night.
