Quick overview
INS Vikramaditya is India's flagship aircraft carrier — a modified Kiev-class vessel purchased from Russia, commissioned into the Indian Navy on 16 November 2013, and currently serving as the senior ship in India's two-carrier fleet alongside the indigenously built INS Vikrant. Displacing 45,000 tonnes across a 284-metre hull, she operates up to 36 aircraft including MiG-29K fighters and Ka-31 AEW helicopters, patrols the Indian Ocean from Karwar Naval Base, and underwent a ₹1,207 crore refit at Cochin Shipyard Limited in late 2024 to extend her service life.
INS Vikramaditya — India's flagship aircraft carrier. The 284-metre STOBAR carrier is home to MiG-29K fighters, Ka-31 AEW helicopters, and over 1,600 personnel.
INS Vikramaditya is not simply a warship. She is a statement about what India's Navy is and where it is going. For a maritime nation surrounded by water on three sides, with the Indian Ocean, Arabian Sea, and Bay of Bengal forming the economic and strategic arteries of the subcontinent, an aircraft carrier is the most visible symbol of the ability to project power, deter adversaries, and protect interests thousands of kilometres from shore.
This article covers everything you need to know about INS Vikramaditya — her origins in the Soviet Navy, the tortured decade-long acquisition and refit that brought her to India, her technical specifications, her air wing and its evolving capabilities, her role in the Indian Ocean's shifting strategic balance, and the critical decisions about her future that India will make over the next decade.

From Baku to Vikramaditya — The Origins of a Warship
INS Vikramaditya began her life not in India, but in a shipyard in Mykolaiv, Ukraine, where her keel was laid in 1978. She was launched as Baku and commissioned into the Soviet Navy in 1987 as a Projékt 1143 "Kreçet" — what NATO classified as a Kiev-class "aircraft-carrying cruiser." The Soviet designation was deliberate: under international treaty obligations, aircraft carriers faced restrictions on passage through the Bosphorus, but cruisers did not. By classifying these ships as cruisers, the Soviet Navy maintained legal access to the Mediterranean through Turkish waters.
Baku was the fourth and final ship of her class. Unlike a conventional Western aircraft carrier, the Kiev-class ships carried a full battery of anti-ship missiles, torpedo tubes, and surface-to-air missiles along their forecastle — making them genuinely hybrid warships as much as aviation platforms. They were designed to hunt and destroy NATO carrier battle groups using their own organic weapons in addition to aircraft.
In 1991, with the collapse of the Soviet Union, Baku was renamed Admiral Gorshkov in honour of Soviet Fleet Admiral Sergei Gorshkov, the man who had built the Soviet blue-water navy. But the newly independent Russian Federation faced catastrophic budget constraints. After a boiler room fire in 1994 required expensive repairs, Admiral Gorshkov was decommissioned in 1996 — too costly to operate in a post-Cold War navy being stripped for funding.
India's Acquisition — The Decade-Long Deal That Nearly Fell Apart
India had long maintained a two-carrier doctrine — the understanding that the Navy requires one carrier on the western coast (Arabian Sea) and one on the eastern coast (Bay of Bengal), with a third in reserve undergoing maintenance. By the late 1990s, with INS Viraat ageing rapidly, India urgently needed a replacement.
Russia offered Admiral Gorshkov for free — with one condition: India would pay for a comprehensive refit that would transform the ship from its hybrid cruiser-carrier configuration into a dedicated aircraft carrier. Negotiations were tortuous. The original deal signed in January 2004 priced the refit at $800 million, with $1 billion more for aircraft and weapons. India agreed, the ship entered Sevmash Shipyard in Severodvinsk, and the problems began immediately.
By 2008, Russia acknowledged that the refit was far more complex and expensive than originally estimated. The ship's hull, despite its apparent size, had deteriorated significantly during its years of lay-up. Steel plating required replacement, cabling runs were vastly underestimated, and the conversion from a missile-cruiser-carrier to a clean STOBAR flight deck demanded wholesale reconstruction of the forward section. Russia demanded an additional $1.2 to $1.5 billion — effectively doubling the price. After bitter diplomatic exchanges, India agreed to the revised cost.
The total acquisition cost ultimately reached approximately $2.35 billion for the refit, plus an additional estimated $1.5 billion for MiG-29K aircraft and associated systems — making INS Vikramaditya one of the most expensive carrier acquisitions in history relative to the ship's original purchase price of zero. The ship completed sea trials in July 2013, aviation trials in September 2013, and was formally commissioned on 16 November 2013 at Severodvinsk. Prime Minister Narendra Modi formally inducted her into the Indian Navy at Karwar on 14 June 2014.
The Transformation — What Changed in the Refit
The refit at Sevmash was not a maintenance job — it was a near-total reconstruction of the ship's mission systems and flight deck. The most visible change was the removal of the entire forward weapons complex — the anti-ship missiles, torpedo tubes, and surface-to-air missile launchers that had occupied the Kiev-class's distinctive angled bow. In their place, a clean STOBAR flight deck was installed, extending the full length of the ship and incorporating a 14.3-degree ski-jump ramp at the bow to assist aircraft in becoming airborne without catapult assistance.
Below decks, approximately 70 to 80 per cent of the ship's systems were replaced with new or modernised equipment. Eight original boilers were removed and replaced with furnace oil-burning modern boilers, an oil-water separator system, and a sewage-water treatment plant meeting international environmental standards. New diesel generators, a Sperry navigation radar system, an updated telephone exchange, and modern data links were installed throughout.
The aviation operations infrastructure was built from scratch. The LUNA landing system for MiG-29K approaches and the DAPS (Deck Approach Path Stabilisation) system for precision approach guidance were installed. The Resistor-E automated air traffic control system was fitted to handle approach, landing, and short-range navigation for aircraft operating up to long distances from the carrier, providing precision guidance to within 30 metres of the flight deck threshold. The CCS Mk II communication complex provides integrated external communications, while the Link II tactical data system connects Vikramaditya into the Indian Navy's wider network-centric operations architecture.
The ship's power generation capacity stands at approximately 18 MW — sufficient to light a small city. Four propeller shafts driven by four steam turbine sets deliver maximum speed of 32 knots. The 1.5 MW diesel generator provides backup power. Radar surveillance systems can detect threats within a 500-kilometre radius of the ship.
INS Vikramaditya's Air Wing — Fighters, Helicopters, and What's Coming
INS Vikramaditya at sea — her MiG-29K carrier-borne fighters are visible on the flight deck. The 14.3° ski-jump ramp is visible at the bow.
MiG-29K — The Current Fighter
INS Vikramaditya's primary combat aircraft is the Mikoyan MiG-29K — the navalised version of the MiG-29 family, developed for carrier operations. India operates 45 MiG-29K and MiG-29KUB (two-seat trainer) aircraft, acquired in two tranches: 16 aircraft in 2004 and 29 more in 2010.
The MiG-29K is an all-weather multirole fighter equipped with the Zhuk-ME radar, folding wings for deck storage, a reinforced undercarriage for the stresses of arrested landings, an arrestor hook, and corrosion-resistant coatings for the maritime environment. It can carry a diverse weapons load across 13 hardpoints, including air-to-air missiles (R-73E, R-77), anti-ship missiles (Kh-35E), precision bombs, and unguided rockets. Its RD-33MK engines produce thrust of approximately 9,000 kg each. Range is approximately 1,000 kilometres in combat configuration.
In practice, the MiG-29K's service record with the Indian Navy has been a persistent operational challenge. Low serviceability rates, maintenance difficulties driven by spare parts availability issues following Russia-Ukraine tensions, and several accidents over the years have meant that the number of mission-ready aircraft at any given time has been fewer than the theoretical fleet size suggests. This operational reality has directly driven the decision to replace them.
Rafale-M — The Future Fighter (2029 Onwards)
In April 2025, India and France signed a €7.4 billion (approximately $8.05 billion) deal for 26 Rafale Marine (Rafale-M) carrier-based fighters — 22 single-seat and 4 twin-seat trainers. The Rafale-M will progressively replace the MiG-29K on both INS Vikramaditya and INS Vikrant. First deliveries are scheduled for 2029, with full deliveries completing through 2030–2031. Indian naval pilots began training with the French Navy in Provence, France, from 2026.
The Rafale-M's selection reflects India's strategic shift away from Russian supply chains. The aircraft offers a combat radius of approximately 1,850 kilometres — nearly double the MiG-29K's 1,000 km — and carries a substantially more capable avionics suite, including the RBE2-AA AESA radar, SPECTRA electronic warfare system, and the MBDA Meteor beyond-visual-range missile in air-to-air configuration. It is also compatible with the Astra Mk-II BVR missile currently in development by DRDO, integration of which is planned for 2026–2027 pending successful trials.
A critical validation took place in 2022 when Dassault demonstrated the Rafale-M performing ski-jump takeoffs and arrested landings at India's Shore-Based Test Facility in Goa — confirming the aircraft could operate from STOBAR carriers without major redesign, despite the French Navy normally operating Rafale-Ms exclusively from catapult-equipped carriers.
Helicopters and Rotary Wing
The carrier's helicopter complement provides three critical capabilities that fixed-wing aircraft cannot. The Kamov Ka-31 performs Airborne Early Warning (AEW) — using its rotating belly-mounted radar to extend the carrier's air picture well beyond what ship-based sensors can see. The Kamov Ka-28 is the Anti-Submarine Warfare (ASW) platform, hunting and engaging enemy submarines that represent the primary threat to surface ships. HAL Dhruv utility helicopters and HAL Chetak aircraft handle search and rescue, plane guard duties, and liaison missions. Together, the helicopter air group extends the carrier's situational awareness and ASW capability to a radius substantially larger than the ship's own sensor suite covers.
The 2024 Refit — ₹1,207 Crore Contract with Cochin Shipyard
In December 2024, the Ministry of Defence signed a ₹1,207 crore contract with Cochin Shipyard Limited (CSL) in Kochi for a short refit and dry docking of INS Vikramaditya. The refit covered avionics upgrades, sensor modernisation, hull maintenance, and systems overhaul. Upon completion, INS Vikramaditya rejoined the active fleet with enhanced combat capability.
The choice of Cochin Shipyard Limited as the refit facility is itself strategically significant. CSL is the same shipyard that built INS Vikrant — India's first indigenous aircraft carrier — from scratch. Having CSL service Vikramaditya develops and deepens the domestic shipyard expertise for maintaining large carriers, reducing India's dependence on foreign facilities (Vikramaditya's earlier major refits were conducted in Russia). The MoD has described this as an important step in establishing CSL as a domestic Maintenance, Repair and Overhaul (MRO) hub for large naval vessels.
2024 Refit Fast Facts: Contract value: ₹1,207 crore (~$145 million) | Facility: Cochin Shipyard Limited, Kochi | Signed: December 2024 | Scope: Short refit and dry docking, avionics and sensor upgrades | Strategic purpose: Establishing CSL as domestic carrier MRO hub
INS Vikramaditya vs INS Vikrant — India's Two Carriers Compared
As of 2026, India operates two aircraft carriers — a capability that fewer than ten nations possess. Understanding the difference between them is essential to understanding India's naval strategy.
| Feature | INS Vikramaditya | INS Vikrant (IAC-1) |
|---|---|---|
| Origin | Soviet/Russian (purchased + refitted) | 100% indigenous (built in India) |
| Commissioned | November 2013 | September 2022 |
| Displacement | 45,000 tonnes | 45,000 tonnes |
| Length | 284 metres | 262 metres |
| Launch system | STOBAR (ski-jump, 14.3°) | STOBAR (ski-jump) |
| Current fighters | MiG-29K (replacing with Rafale-M from 2029) | MiG-29K (replacing with Rafale-M / TEDBF) |
| Indigenous content | ~80% of systems replaced (but hull is Soviet) | >76% indigenous by value |
| Radar | Resistor-E ATC, long-range air surveillance | MF-STAR AESA multi-function radar (indigenous) |
| Expected retirement | 2037 (or 2052 with MLU) | 2060s+ |
| Operational coast | Western Fleet (Arabian Sea) | Eastern Fleet (Bay of Bengal) |
INS Vikramaditya's Strategic Role in the Indian Ocean
An aircraft carrier's value lies not just in what it can do, but in what adversaries must assume it can do. INS Vikramaditya, operating as the flag of the Western Naval Command's Carrier Battle Group, forces any adversary planning operations in the Arabian Sea and northern Indian Ocean to account for the presence of a floating airbase capable of projecting air power across a radius of hundreds of kilometres.
The carrier's 500-kilometre radar surveillance envelope, combined with the 1,000-kilometre combat radius of her MiG-29K fighters (extending to 1,850 km with the incoming Rafale-M), means that a well-positioned Vikramaditya battle group can threaten, monitor, or intercept anything in a substantial section of the western Indian Ocean — from the mouth of the Persian Gulf to the waters west of Sri Lanka.
This capability was demonstrated most vividly during and after Operation Sindoor in May 2025. According to Indian Navy Chief Admiral Dinesh Tripathi, India's carrier battle group deployment forced Pakistan's entire naval fleet to remain confined to port for over seven months — an extraordinary maritime denial achievement without firing a single naval weapon. The economic cost to Pakistan of disrupted shipping and constrained maritime activity during this period was significant.
Beyond deterrence, INS Vikramaditya has accumulated a substantial operational record. Since commissioning in 2013, she has logged over 100,000 nautical miles, participated in the Malabar exercises with the US, Japanese, and Australian navies, conducted bilateral exercises with the Italian, French, and British navies, and maintained consistent patrol presence in the Indian Ocean Region. In June 2024, in a rare display of combined carrier power, both INS Vikramaditya and INS Vikrant led a strike force of 35 MiG-29K aircraft in a joint war drill in the Arabian Sea — the first time India had exercised a genuine two-carrier formation in a combat-simulated environment.
The Future — Will INS Vikramaditya Serve Until 2052?
INS Vikramaditya cross-section and key statistics. As of February 2025, the carrier has an estimated remaining operational life of 10 years before a critical structural audit decision point in 2035.
As of 3 February 2025, Indian Navy assessments indicate that INS Vikramaditya has approximately 10–12 years of remaining operational life in her current configuration — pointing to a decommissioning around 2035–2037 unless a Mid-Life Upgrade is approved and successfully executed.
The structural challenge is fundamental: the hull's core was laid down in 1978. Despite the replacement of the vast majority of systems during the Sevmash refit and subsequent maintenance, the underlying steel structure is now 48 years old — a "Soviet relic," as one defence official described it, increasingly susceptible to metal fatigue and corrosion in the warm, saline waters of the Indian Ocean. The carrier has experienced a small number of fire incidents and boiler issues during her Indian service, consistent with the Kiev class's historical pattern across all four ships of the class.
The Indian Navy plans a comprehensive structural audit at Cochin Shipyard Limited in approximately 2035. If the audit confirms sufficient hull integrity, a mid-life upgrade incorporating new indigenous systems — potentially including DRDO's MF-STAR AESA radar, hybrid propulsion modifications, and other improvements — could extend Vikramaditya's service life to approximately 2052. If the structural condition is found wanting, the cost of a full hull-strengthening and life-extension programme could rival the cost of building a new carrier — making decommissioning by 2037 the economically rational choice.
This uncertainty directly drives India's push for the Indigenous Aircraft Carrier 2 (IAC-2) — provisionally called INS Vishal. Formal sanction for IAC-2 was under active consideration as of early 2026, with the Defence Acquisition Council expected to provide Acceptance of Necessity clearance. A 65,000-tonne CATOBAR carrier incorporating EMALS launch technology, designed for 28+ fighters and UAV integration, IAC-2 is intended to replace Vikramaditya in the fleet when the older carrier eventually retires. With a typical carrier build timeline of 10–12 years from sanction to commissioning, the timing of IAC-2's approval is directly linked to Vikramaditya's expected decommissioning date.

Frequently Asked Questions About INS Vikramaditya
What is INS Vikramaditya?
INS Vikramaditya is India's flagship aircraft carrier — a modified Kiev-class vessel originally built as Baku for the Soviet Navy in 1987, purchased by India, comprehensively refitted at Sevmash Shipyard in Russia, and commissioned into the Indian Navy on 16 November 2013. Displacing 45,000 tonnes across a 284-metre hull, she is a STOBAR carrier operating MiG-29K fighters and various helicopter types from Karwar Naval Base on India's western coast.
What is the top speed of INS Vikramaditya?
INS Vikramaditya can reach a maximum speed of 32 knots — approximately 59 kilometres per hour. At the more economical cruising speed of 18 knots, she has a range of 13,500 nautical miles (25,000 km).
How many aircraft can INS Vikramaditya carry?
INS Vikramaditya can accommodate up to 36 aircraft in total — typically 24 fixed-wing MiG-29K fighters and 10–12 rotary-wing aircraft including Ka-31 AEW helicopters, Ka-28 ASW helicopters, HAL Dhruv, and HAL Chetak. From 2029, MiG-29Ks will progressively be replaced by Rafale-M fighters.
What happened to INS Vikramaditya's predecessor INS Viraat?
INS Viraat — formerly HMS Hermes of the Royal Navy and a veteran of the 1982 Falklands War — served as India's aircraft carrier from 1987 to 2017, making her the world's longest-serving aircraft carrier. She was decommissioned in March 2017, and despite multiple proposals to convert her into a museum ship, she was eventually scrapped at Alang, Gujarat in 2021.
What is the difference between INS Vikramaditya and INS Vikrant?
INS Vikramaditya is a refitted Soviet-era vessel, while INS Vikrant (IAC-1), commissioned in September 2022, is India's first fully indigenous aircraft carrier — designed and built entirely in India at Cochin Shipyard Limited. Both are STOBAR carriers of similar displacement (45,000 tonnes), but Vikrant is slightly shorter (262 m vs 284 m), carries more advanced indigenous systems including the MF-STAR AESA radar, and has a significantly longer expected service life extending into the 2060s.
Will INS Vikramaditya be decommissioned?
INS Vikramaditya is expected to serve until approximately 2037 in her current configuration. A comprehensive structural audit planned for 2035 at Cochin Shipyard will determine whether a mid-life upgrade extending service to 2052 is technically and economically viable. If the hull assessment is unfavourable, decommissioning by 2037 is the likely outcome. India's planned Indigenous Aircraft Carrier 2 (IAC-2/INS Vishal) is intended to replace her.
What is INS Vikramaditya's role in India's navy?
INS Vikramaditya serves as the flagship of the Indian Navy's Western Fleet and leads the Western Naval Command's Carrier Battle Group. Her primary roles are air superiority and strike in the Arabian Sea and western Indian Ocean, anti-submarine warfare coordination, power projection and deterrence against adversary naval forces, and maintaining India's continuous carrier presence on the western coast. During Operation Sindoor in 2025, her battle group's positioning forced Pakistan's entire navy to remain in port for over seven months.
Conclusion
INS Vikramaditya's story is a compressed history of India's naval ambitions — the difficult decades of seeking a replacement for INS Viraat, the tortured acquisition that nearly collapsed under cost overruns, the transformation of a Soviet hybrid warship into a functional STOBAR carrier, and now the transition to a domestically serviced, Rafale-equipped platform at the heart of a genuine two-carrier fleet.
She is simultaneously a symbol of what India has achieved and a reminder of what still needs to be built. The MiG-29K's service challenges have been solved — at substantial cost — by the Rafale-M deal. The refit at CSL in 2024 buys her another decade of relevance. The structural audit in 2035 will decide her ultimate fate. And the timing and approval of IAC-2 will determine whether India maintains its two-carrier doctrine through the 2040s without a gap.
For now, INS Vikramaditya remains exactly what she has been since 2013: the most visible symbol of India's intent to be not just a regional naval power, but a blue-water force capable of projecting credible military capability across the Indian Ocean and beyond.
