On 13 June 2026, the offshore patrol vessel INS Sharda departed Colombo, Sri Lanka, wrapping up a port call that the Ministry of Defence described as deepening maritime cooperation between the two neighbours. On paper it was a routine visit — small-arms drills, firefighting and first-aid training for Sri Lankan Navy personnel, friendly sports fixtures, cross-deck visits and a courtesy call by the Commanding Officer on India's High Commissioner, Shri Santosh Jha. But for an NDA aspirant, this small event is a doorway into one of the most testable themes in defence GK: how warships do diplomacy, and the doctrines — SAGAR and now MAHASAGAR — that frame India's role in the Indian Ocean.
What Actually Happened — and Why It Counts as "Diplomacy"
A port call (or goodwill visit) is when a naval ship visits a friendly foreign harbour to build relationships rather than to fight. The MoD release lists the building blocks of every such visit: capacity-building (training the host navy in small-arms handling, basic firefighting, first aid and rescue), professional exchanges and cross-deck visits (sailors tour each other's ships to learn procedures), and interoperability (practising so two navies can operate together in a real crisis). Rear Admiral Jagath Kumara, Commander of Sri Lanka's Western Naval Area, visited the ship — the kind of senior engagement that signals trust between services.
This is the essence of naval diplomacy: using the navy as a tool of foreign policy in peacetime. Navies are uniquely suited to it because a warship is sovereign Indian territory that can sail into a partner's waters without basing rights, deliver aid, or simply show the flag.
Meet the Ship: INS Sharda and the Sukanya Class
INS Sharda (P55) is a Sukanya-class offshore patrol vessel (OPV), commissioned on 27 October 1991. A few exam-friendly specifics:
- The Sukanya class is a group of large-hulled but lightly armed patrol ships built primarily to police India's Exclusive Economic Zone (EEZ) — the 200-nautical-mile belt where a coastal state controls marine resources. They are workhorses for anti-piracy, search-and-rescue, fishery protection and exactly this kind of diplomatic port call.
- The lead ships were built with foreign collaboration (Korea), and vessels of the class are named after notable women from Indian epics and tradition — Sukanya, Subhadra, Suvarna, Savitri, Sharda, Sujata.
The takeaway for an aspirant: not every "deployment" needs a destroyer. An OPV is cheap to run and perfect for sustained presence missions across the Indian Ocean Region (IOR). India's maritime geography — a 7,500-km coastline straddling the world's busiest sea lanes — makes this everyday presence a strategic asset, a point worth revising alongside India's physical and maritime geography.
SAGAR → MAHASAGAR: The Doctrine You Must Know
The release explicitly ties the visit to the MAHASAGAR vision — and this evolution is prime NDA/CDS material.
- In 2015, on a visit to Mauritius, PM Modi articulated SAGAR — "Security and Growth for All in the Region." SAGAR (the word means "sea") became India's guiding framework for the Indian Ocean: secure India's mainland and islands, deepen economic and security cooperation with maritime neighbours, and act as a "net security provider" in the region.
- In March 2025, again from Mauritius, the PM unveiled the successor vision MAHASAGAR — "Mutual and Holistic Advancement for Security and Growth Across Regions." MAHASAGAR (the word means "ocean") widens the lens from the Indian Ocean region to the Global South more broadly, and folds in trade, capacity-building, technology and sustainability alongside security.
A neat mnemonic: SAGAR = the sea (region); MAHASAGAR = the ocean (across regions). The Colombo visit — training the host navy, building interoperability — is MAHASAGAR in miniature.
The Roles of the Indian Navy
Examiners often pair "naval diplomacy" with the Indian Maritime Doctrine's four roles of a navy. Worth memorising:
| Role | What it means | Example |
|---|---|---|
| Military | War-fighting, sea control, deterrence | Carrier battle groups, submarines |
| Diplomatic | Foreign-policy tool in peacetime | INS Sharda's Colombo port call |
| Constabulary | Policing — anti-piracy, EEZ patrol | Sukanya-class OPVs |
| Benign | Humanitarian aid, disaster relief (HADR) | Evacuations, tsunami/cyclone relief |
India's neighbourhood diplomacy also runs through policies like "Neighbourhood First" and the earlier Indian Ocean outreach, which you can connect to your broader current-affairs and international-relations notes.
The Sukanya Class — Knowing the Family
A port call is "constabulary plus diplomatic," and the Sukanya class was built exactly for it. The class has six vessels in Indian service — INS Sukanya (P50), Subhadra (P51), Suvarna (P52), Savitri (P53), Sharda (P55) and Sujata (P56) — each around 1,890 tonnes full load, 101 m long, with a top speed of about 21 knots. They carry a light gun and a helicopter deck, and are used for EEZ surveillance, anti-piracy patrols off Africa, fishery protection, search-and-rescue and goodwill visits of exactly this kind. (Two related ships were transferred to friendly navies, underlining their diplomatic utility.) The lesson examiners reward: India fields a graded fleet — destroyers and carriers for war-fighting, frigates and corvettes for sea control, and OPVs like the Sukanya class for the everyday, lower-intensity "presence" missions that keep the Indian Ocean stable.
India–Sri Lanka: The Maritime Relationship Behind the Visit
Sri Lanka sits astride India's southern sea lanes, so this is not just a courtesy stop. A few connectable facts for a fuller answer:
- SLINEX (Sri Lanka–India Naval Exercise), conceptualised in 2005, is the flagship bilateral naval drill; its 12th edition (SLINEX-2025) was held off Colombo in August 2025. INS Sharda's visit feeds the same goal — interoperability.
- Both nations are members of the Colombo Security Conclave (CSC), a maritime-security grouping that also includes the Maldives, Mauritius and Bangladesh (with Seychelles as an observer), focused on threats like piracy, terrorism, trafficking and disaster response.
- The relationship sits inside a wider Indian Navy diplomacy calendar — the multilateral MILAN exercise at Visakhapatnam and the AIKEYME wargame with African navies — all expressions of the SAGAR/MAHASAGAR idea of India as a "net security provider."
A useful contrast for revision: the Indian Navy's three commands are the Western Naval Command (Mumbai), Eastern Naval Command (Visakhapatnam) and the training-focused Southern Naval Command (Kochi) — and a fourth, fully integrated tri-service command, the Andaman and Nicobar Command (Port Blair), India's only theatre command. Patrol vessels of the Sukanya class operate under these commands to keep a continuous watch over the island territories and choke points (the Strait of Malacca, the Six/Ten/Nine Degree Channels) that make the Bay of Bengal and Arabian Sea strategically vital.
Put together, INS Sharda in Colombo is one frame of a much larger picture: India using a modest patrol ship to convert geography (a 7,500-km coastline at the centre of the Indian Ocean) into durable partnerships.

📋 How this gets asked (PYQ pattern)
NDA/CDS defence GK reliably tests ship-to-class matching (name the class of a given ship), the SAGAR full form and its 2015 Mauritius origin, and the roles of the navy. The fresh, this-cycle hooks examiners love: the upgrade from SAGAR to MAHASAGAR (2025) and the INS Sharda → Sukanya-class OPV link. Pair this with the standard "EEZ = 200 nautical miles" fact and the meaning of a "net security provider."
