The Indian Navy: History, Structure and Command

Origins: From the Bombay Marine to the Indian Navy

The Navy's own history page traces the service to the East India Company's marine at Bombay, and then through a series of name changes.

Naval HQ, the Chief and the Principal Staff Officers

Naval Headquarters is in New Delhi and is styled the Integrated Headquarters of the Ministry of Defence (Navy). Like Army HQ, it plans, raises, trains and equips; the commands and fleets operate.

• Chief of the Naval Staff (CNS): Adm Krishna Swaminathan has held the appointment since 31 May 2026. The CNS is an Admiral, commands the Navy and sits on the Chiefs of Staff Committee. Past holders are on Chiefs of the Naval Staff.
• Chief of Defence Staff (CDS): Gen N S Raja Subramani is the government's principal military adviser and does not command the Navy. See the CDS page.

The CNS is helped by four Principal Staff Officers (PSOs), all Vice Admirals according to PIB's appointment releases:

Identity: Motto, Crest and the Naval Ensign

Motto. The Navy's motto is "Sam No Varunah", a Vedic invocation to Varuna that PIB renders as "May the Ocean God be Auspicious unto us". It was adopted on the suggestion of C. Rajagopalachari, the first Indian Governor-General. It sits on a ribbon below the crest.

Crest. The crest shows the Ashoka Lion above an anchor. On 4 December 2022 the old "foul" anchor (with a rope round it) gave way to a clear anchor, which the Navy says stands for steadfastness and clarity of purpose.

The ensign. The naval ensign is the flag flown on ships and shore establishments. Its history is a favourite exam topic because it changed in 2022.

The new ensign was dedicated to Chhatrapati Shivaji Maharaj. PIB says the octagon draws on his seal, and that its eight sides stand for the eight directions, signifying the Navy's reach. The government described the change as a move away from the colonial past; as a factual matter, the cross that was dropped had come down from the pre-Independence ensign.

Navy Day, 4 December, and Operation Trident

The Navy marks Navy Day on 4 December for Operation Trident, its missile-boat attack on Karachi harbour in the 1971 war. PIB records that the boats fired missiles on ships, an oil installation and shore defences at Karachi. In the same war, aircraft from INS Vikrant struck Chittagong and Khulna in the east. The wider story is on the 1971 war page.

Press accounts name the strike force as three missile boats, INS Nipat, INS Nirghat and INS Veer, escorted by INS Kiltan and INS Katchall, and credit the sinking of the destroyer PNS Khaibar and the minesweeper PNS Muhafiz.

Fleets Versus Commands, Explained Simply

Candidates mix these up more than any other Navy fact. Think of a command as a regional headquarters on land and a fleet as the ships at sea.

The two operational commands look after bases, dockyards, logistics and area security, and the fleets are the fighting force that sails from those bases. PIB's own wording shows the split: a FOC-in-C heads a command, while a Flag Officer Commanding takes over a fleet in a ceremonial parade at the dockyard. Southern Naval Command is the Navy's training command, and its Flag Officer Sea Training works under it.

There is one more headquarters outside this scheme: the Andaman and Nicobar Command, headed by Vice Adm Vineet McCarty, which is a tri-service command. See its page and the plan for merging commands in theatre commands. The Army equivalent is on the Indian Army hub, and each service's ranks are lined up on rank equivalence.

Guided Tour: Every Page in the Navy Section

Read in this order if you are starting from zero.

The Navy's neighbours in the maritime space have their own sections: Indian Coast Guard and Indian Air Force. Across services, see naval exercises, BrahMos and Indian Ocean chokepoints. For how the fleet works with partners, read our reports on the Eastern Fleet in Vietnam and the Navy Chief in Mauritius.

Exam pins

Asked in past papers

Navy questions come in two kinds: fixed facts on ranks and history, and ship-name questions tied to the news of that year.

Where to Go Next

For the career side, read career in the Indian Navy and the women in defence forces page. Boards ask "know your service", so keep our SSB interview tips open next to this page, then read defence days and ceremonial traditions (the President's Colour is a Navy "first"). Navy entry for graduates is through the CDS course to the Indian Naval Academy, and for 12th-pass candidates through the Naval wing of the NDA, which our NDA batches cover with weekly tests and SSB training.
