Background and Context
A ship formally enters naval service when it is "commissioned". At the same ceremony the national flag is hoisted for the first time and the commissioning pennant is unfurled. This time three different kinds of ships were commissioned in one ceremony - for warfare, maritime survey and an anti-submarine role in coastal waters.
Why in the News
According to the Ministry of Defence's press release (PIB, 21 June 2026), Prime Minister Narendra Modi commissioned INS Dunagiri (stealth frigate), INS Sanshodhak (survey vessel large) and INS Agray (shallow-water anti-submarine craft) into the Navy at Kolkata on 21 June 2026. Navy Chief Admiral Krishna Swaminathan was also present at the ceremony.
Key Facts and Figures
| The event | Joint commissioning of three ships, Kolkata, West Bengal, 21 June 2026; the Prime Minister the chief guest (PIB, Ministry of Defence, 21 June 2026) |
|---|---|
| INS Dunagiri | The fifth frigate of the Project 17A Nilgiri class and the second ship of this class built at Garden Reach Shipbuilders and Engineers (GRSE). Supersonic surface-to-surface missiles, air-defence system, anti-submarine capability and the capacity to carry a helicopter. |
| INS Sanshodhak | The fourth ship of the Survey Vessel (Large) class; four survey motor boats; two engines; according to the release, it can also be converted like a hospital ship. |
| INS Agray | The fifth ship of the shallow-water anti-submarine craft (ASW SWC) series; sonar, torpedoes, anti-submarine rockets and a combat management system; propelled by waterjets. |
| Construction | All three ships were designed by the Navy's Warship Design Bureau and GRSE, and built by GRSE. Participation of more than 200 MSMEs and more than 75 per cent indigenous content is stated (the release). |
| The Navy Chief's statement | The Navy Chief said that this happened in Kolkata only 17 months after the commissioning of independent India's first three ships in Mumbai (quoted in the release). |
| The Prime Minister's statements | According to the Prime Minister, more than 40 indigenous warships and submarines have joined the Navy in the last few years and 45 large ships are under construction. He put defence production at about ₹1.8 lakh crore now, up from about ₹40,000 crore in 2014. These are claims from the Prime Minister's speech. |
| Announcement on shipbuilding | The Prime Minister mentioned an incentive package of ₹70,000 crore for the maritime sector (according to the speech). |
Three Different Roles
Combat capability: Dunagiri: The Nilgiri-class frigate is multi-role. According to the release, it has modular construction, missiles, air defence, anti-submarine weapons and a helicopter facility. The release did not give the names or numbers of the missiles.
Maritime survey: Sanshodhak: Survey vessels collect precise data on the sea's depth, floor and currents. According to the release, it will also serve India's "ocean" vision and surveys for friendly countries. The Prime Minister noted that 21 June is also World Hydrography Day.
Coastal anti-submarine: Agray: The threat of submarines and mines in shallow water is different from that in the deep sea. Small, agile ships are needed for this. The release describes it as enhancing anti-submarine and mine-warfare capability in shallow waters.
Why This Subject Matters
Self-reliance and construction capability: The release's main argument is indigenous design and construction. More than 75 per cent indigenous content is a government figure; the release does not identify the type of content.
Role in the Indian Ocean: According to the release, these ships will enhance the capacity for humanitarian assistance, disaster relief, evacuation of citizens and anti-piracy operations. The release links this to India's role as a "stabilising force" in the Indo-Pacific.
Points of Debate and Cautions
The tone of the release and the speech: This is a government release with a tone of achievement. The figures on defence production and ships under construction are given in the Prime Minister's speech; we have not independently verified them.
Capability versus deployment: Commissioning means the ship has joined service. The release does not give information on its full operational deployment or use in any operation, and neither do we.
Source and limits: We read only the Ministry of Defence's PIB release (https://www.pib.gov.in/PressReleasePage.aspx?PRID=2276104&lang=1®=3). The ships' cost, displacement and full details of weapons are not in the release and we have not added them. We have not checked the post-commissioning status.
Difference from previous articles: We found no article on this commissioning among our published articles; a search for Dunagiri, Sanshodhak, Agray and GRSE returned no results.
Way Forward
Read everything in this article as the position of the government release of 21 June 2026. We have not checked the ships' deployment, further commissions or the progress of ships under construction.
The Difference in Concepts
Keep four things separate: (1) the release's facts (ships, class, builder, date); (2) the statements of the Prime Minister and the Navy Chief; (3) government figures we have not independently verified; and (4) our interpretations.
Mains Perspective
GS-III: defence, internal and maritime security, indigenisation; GS-II: India's role in the Indian Ocean. Keep the release's facts and your own opinion separate in the answer.
Answer Outline
Introduction: What commissioning is.
Main Body: The three ships and their roles; indigenous construction; the role in the Indian Ocean; the limits of the figures.
Conclusion: Link indigenous ships in three different roles to a balanced fleet and construction capacity. Do not treat commissioning as full operational deployment, and keep government claims on indigenous content and production, and their limits, clear.
Sources
All facts are from this one government release. It is the government's side and we have not verified the speech's figures.
Remember: According to the Ministry of Defence's release, three ships joined the Navy together at Kolkata on 21 June 2026: the stealth frigate Dunagiri, the survey vessel Sanshodhak and the shallow-water anti-submarine craft Agray. Construction was by GRSE and more than 75 per cent indigenous content is stated.
