Indian Navy: History, Fleet, Role and Future Plans

The Indian Navy is the maritime branch of the Indian Armed Forces, responsible for safeguarding India’s 7,516‑kilometre coastline and protecting its maritime trade routes. Established in 1947, it now operates more than 70 commissioned ships, submarines and aircraft, making it the fourth largest navy in the world by tonnage.

What are the primary missions of the Indian Navy?

The Indian Navy’s core missions include sea‑control, power‑projection, humanitarian assistance, and maritime diplomacy. It conducts anti‑piracy patrols in the Gulf of Aden, provides disaster relief after cyclones, and supports joint exercises with friendly navies to enhance interoperability.

How big is the Indian Navy?

As of March 2024, the Indian Navy employs roughly 150,000 personnel, including 45,000 officers and 105,000 sailors. Its active fleet comprises 67 warships, 7 aircraft carriers, 14 submarines, and over 100 aircraft, supported by auxiliary vessels and coastal patrol boats.

The table below summarises the main combat and support platforms in service.

When was the Indian Navy founded and how has it evolved?

The navy traces its origins to the Royal Indian Navy formed on 1 October 1934 under British rule. After India’s independence on 15 August 1947, it was renamed the Indian Navy on 26 January 1950 and has since expanded from a modest coastal force to a blue‑water navy with nuclear capabilities.

Key milestones

Major events that shaped the service include:

• 1949 – first indigenous ship (INS Ranjit) commissioned.
• 1971 – successful naval blockade during Indo‑Pak war.
• 1999 – acquisition of first aircraft carrier (INS Vikramaditya, commissioned 2013).
• 2013 – commissioning of INS Vikramaditya, India’s first STOBAR carrier.
• 2022 – commissioning of INS Vikrant, India’s first domestically built carrier.
• 2021 – induction of first indigenous nuclear submarine (INS Arihant) operational.
• 2024 – launch of Project 75I for 5 advanced conventional submarines.

What major assets does the Indian Navy operate?

The Indian Navy’s most visible power‑projection tools are its aircraft carriers, submarines and missile‑armed surface combatants. These platforms enable the force to conduct strike missions, anti‑submarine warfare, and sustained presence in the Indian Ocean Region (IOR).

Aircraft carriers

India currently operates two carriers. INS Vikramaditya, a modified Kiev‑class ship purchased from Russia, entered service in 2013 and can launch up to 30 MiG‑29K fighters. INS Vikrant, launched in 2020 and commissioned in September 2022, is the first fully indigenously built carrier, supporting 30–32 aircraft and featuring a ski‑jump for STOBAR operations.

Submarines

The submarine fleet consists of 14 boats, including three nuclear‑powered attack submarines (INS Arihant, INS Arighat, INS Vela) and eleven conventional diesel‑electric boats. The nuclear fleet provides strategic deterrence, while the conventional submarines are equipped with heavyweight torpedoes and the Club‑S anti‑ship missile.

How does the Indian Navy contribute to regional security?

By patrolling the Arabian Sea, Bay of Bengal and the wider Indian Ocean, the navy deters piracy, safeguards sea‑lines of communication (SLOCs) that carry over 80 % of India’s trade, and participates in multinational exercises such as Malabar, AUSMIN and IISS‑led forums. Its humanitarian missions have delivered relief after the 2004 tsunami and the 2020 cyclones in Odisha.

What are the future plans for the Indian Navy?

The navy’s 2030 vision aims to achieve a ‘blue‑water’ capability with three aircraft carriers, a fleet of 75 surface combatants and 30 submarines, including six nuclear‑powered units. Ongoing projects include the construction of the indigenous carrier‑class ‘Project 75I’, the acquisition of 8 new stealth frigates (Project 18), and the induction of unmanned surface and underwater vehicles for surveillance.

Upcoming projects

Key programmes slated for delivery by 2030 are:

• INS Vikrant‑II (second indigenously built carrier, expected 2028).
• Six additional nuclear attack submarines under the Arihant‑class.
• Eight Project 18 stealth frigates with Mk 41 VLS.
• Twelve P‑75I conventional submarines with Air‑Independent Propulsion.
• Network‑centric command and control system (NCCS) for integrated maritime domain awareness.

What are the Indian Navy’s major international collaborations?

The Indian Navy regularly trains with the United States, Japan, France and Australia through joint exercises such as Malabar, Varuna and INDRA. It also participates in the Indian Ocean Naval Symposium (IONS) and contributes ships to UN peacekeeping missions, notably off the coast of Somalia (UNOSOM) and in the Gulf of Aden. These partnerships enhance interoperability, share anti‑piracy intelligence and promote a free and open Indo‑Pacific.

How is the Indian Navy organized?

The navy is divided into three operational fleets – Western, Eastern and Southern – each commanded by a Vice Admiral. A separate command, the Andaman and Nicobar Command, handles joint tri‑service operations in the strategic archipelago. Training and doctrine are overseen by the Indian Naval Academy at Ezhimala and the Naval War College in Goa. Support functions such as logistics, engineering and medical services fall under the Naval Headquarters in New Delhi.

Notable operations

Since independence, the navy has taken part in several high‑profile missions: Operation Cactus (1988) rescued the Maldives from a coup, Operation Rahat (2013) evacuated civilians from Yemen, and anti‑piracy patrols in the Gulf of Aden that have rescued over 1,500 merchant vessels. These actions demonstrate the force’s ability to project power and provide humanitarian assistance far beyond India’s shores.

What emerging technologies are shaping the Indian Navy’s future?

The service is investing in network‑centric warfare, artificial‑intelligence‑driven decision support, and autonomous platforms. The Navy’s Project Navy 2000 includes plans for unmanned surface vehicles (USVs) for mine counter‑measures, underwater drones for reconnaissance, and a cloud‑based combat management system to integrate data from satellites, aircraft and ships. Trials of laser‑guided missiles and directed‑energy weapons are also underway, aiming to boost defensive capability against swarming threats.

Frequently Asked Questions

When was the Indian Navy officially established?

The Indian Navy traces its roots to the Royal Indian Navy founded on 1 October 1934, and was officially renamed the Indian Navy on 26 January 1950 after independence.

INS Vikramaditya is a refurbished Russian‑built Kiev‑class carrier commissioned in 2013, while INS Vikrant is India’s first fully indigenously built carrier, commissioned in 2022 with a ski‑jump for STOBAR operations.

How many nuclear submarines does India currently have?

India operates three nuclear‑powered attack submarines – INS Arihant, INS Arighat and INS Vela – forming the core of its sea‑based strategic deterrent.

What is Project 75I?

Project 75I is a major procurement programme to build five advanced conventional submarines equipped with air‑independent propulsion, slated for delivery in the late 2020s to expand India’s under‑sea fleet.
