INS Vikramaditya (Sanskrit, Vikramāditya meaning "Brave as the Sun"[note 1]) is a modified Kiev-class aircraft carrier which entered into service with the Indian Navy in 2013. She has been renamed in honour ofVikramaditya, a legendary 1st century BC emperor of Ujjain, India.

Originally built as Baku and commissioned in 1987, the carrier served with the Soviet (until the dissolution of the Soviet Union) and Russian Navies before being decommissioned in 1996 as she was too expensive to operate on a post-Cold War budget.[16][17][18] The carrier was purchased by India on 20 January 2004 after years of negotiations at a final price of $2.35 billion.[1] The ship successfully completed her sea trials in July 2013[19] and aviation trials in September 2013.[20] She was formally commissioned on 16 November 2013 at a ceremony held at Severodvinsk, Russia.[21][22] On 14 June 2014, Prime Minister of India Narendra Modi formally inducted INS Vikramaditya into the Indian Navy and dedicated it to the Nation.[23][24]



Baku entered service in 1987, but was deactivated in 1996 because she was too expensive to operate on a post-Cold War budget. This attracted the attention of India, which was looking for a way to expand its carrier aviation capabilities.[25] On 20 January 2004, after years of negotiations, Russia and India signed a deal for the sale of the ship. The ship was free, while India would pay US$800 million for the upgrade and refit of the ship, as well as an additional US$1 billion for the aircraft and weapons systems. The navy looked at equipping the carrier with the E-2C Hawkeye, but decided not to.[26] In 2009, Northrop Grumman offered the advanced E-2D Hawkeyeto the Indian Navy.[27]

The deal also included the purchase of 12 single-seat Mikoyan MiG-29K 'Fulcrum-D' (Product 9.41) and four dual-seat MiG-29KUB aircraft (with an option for 14 more aircraft) at US$1 billion, six Kamov Ka-31 "Helix" reconnaissance and anti-submarine helicopters, torpedo tubes, missile systems and artillery units. Facilities and procedures for training pilots and technical staff, delivery of simulators, spare parts, and establishment maintenance on Indian Navy facilities were also part of the contract.

The upgrade plans involved stripping all the weaponry and missile launcher tubes from the ship's foredeck to make way for a "short take-off but assisted recovery" (STOBAR) configuration,[28] this modification converted the Gorshkovfrom a hybrid carrier/cruiser to a pure carrier.

The announced delivery date for INS Vikramaditya was August 2008, which would allow the carrier to enter service just as the Indian Navy's only light carrierINS Viraat retired. While Viraat's retirement had been pushed out to 2010–2012,[29] it is undergoing a final refit which will enable her to serve through 2016.[30] The issue with the delays was compounded by the ongoing cost overruns, resulting in high-level diplomatic exchanges to get these issues resolved. India finally agreed to pay an additional US$1.2 billion for the project, more than doubling the original cost.[31] However, ongoing delays with the Vikramaditya's delivery schedule, pushed the delivery to 2013. The indigenous Vikrant-class aircraft carrierwas delayed by at least a year and was expected to be commissioned at the earliest in 2013 from the proposed 2012.[32]

In July 2008, it was reported that Russia was increasing the total price to US$3.4 billion, blaming unexpected cost overruns on the deteriorated condition of the ship.[33] India has paid US$400 million as of November 2008. However, Russia even threatened to scrap the deal altogether if India did not pay the amount.[34] In December 2008, government sources in India stated that the Cabinet Committee on Security (CCS) had finally decided in favour of purchasing Admiral Gorshkov as the best option available.[35] The Comptroller and Auditor General of India (CAG) criticised the fact thatVikramaditya would be a second-hand warship with a limited life span, which would be 60% costlier than a new one, and there was a risk of further delay in its delivery.[36]

The conversion plans for the ship have seen all the armament from the foredeck removed, including the P-500 Bazalt cruise missile launchers and the four Antey Kinzhal surface-to-air missile launchers, to make way for a 14.3° bowski-jump ramp.

The Indian Navy Chief of Naval Staff Admiral Sureesh Mehta defended the price for the warship saying: "I can't comment on the CAG. But you all are defence analysts, can you get me an aircraft carrier for less than USD two billion? If you can, I am going to sign a cheque right now". The statement from the Chief of Naval Staff possibly indicates that the final deal could be in excess of US$2 billion. When asked about CAG's finding that the navy had not done its risk analysis before going in for the ship, he said, "I can ensure you that there is no such thing. There is no question, we have been looking at the ship since the late 90s."[37]

On 2 July 2009, Russian President Dmitry Medvedev said that the carrier should be completed as soon as possible so she could be delivered to India in 2012.[38] On 7 December 2009, Russian sources indicated that final terms had been agreed on, but no delivery date was set.[39] On 8 December 2009, it was reported that India and Russia ended the stalemate overAdmiral Gorshkov price deal by agreeing on a price of US$2.2 billion. Moscow was asking for US$2.9 billion for the aircraft carrier, nearly three times the price that was originally agreed between the two sides in 2004. On the other hand, New Delhi wanted the price to be scaled back to US$2.1 billion.[40][41] Both governments finalsed the price of Admiral Gorshkov at US$2.35 billion on 10 March, a day ahead of Russian Prime Minister Vladimir Putin's two-day visit to India.[1]

In April 2010, a scandal over the project emerged when it was announced that a senior Indian Navy officer had probably been blackmailed to influence the negotiations over the cost of Admiral Gorshkov to India.[42] Commodore Sukhjinder Singh had been a senior figure supervising the refit of the carrier, working as the principal director for the project. He was discharged from service due to this incident.[43]

The hull work was completed by 2008[44] and Vikramaditya was launched on 4 December 2008.[45] Around 99% of the structural work and almost 50% of the cabling work had been completed by June 2010. Almost all of the large equipment, including engines and diesel generators, was installed.[46] A naval MiG-29K prototype aircraft was used to test the deck systems of Vikramaditya in 2010.[47]

All reconfiguration work was completed at Severodvinsk, Russia; however it was delayed by three years due to underestimation of the amount of cabling needed.[48] An expert level discussion on technical and financial matters was held between India and Russia to sort out the issues.[49] The MiG-29K entered operational service with India in February 2010. A compromise was finalised and India was to pay an extra undisclosed amount. Russia was to install new systems instead of repairing the old ones.[50]

On 1 June 2010, the Times of India reported a naval officer saying: "With India earlier this year agreeing to the revised refit cost of $2.33 billion for Gorshkov after three years of bitter wrangling since the earlier agreement inked in January 2004 had earmarked only $974 million for it, Russia has appointed a high-level apex committee to oversee the work on the carrier." The ship was to go for harbour trials by early 2011 to ensure it could be handed over to India by December 2012 or so.[46][51] Dock trials began on 1 March 2011. The focus of these trials was on the main power generation units and the radio-electronic armament systems, manufactured in India.[52][53] Indian Navy personnel began training on Vikramaditya in April 2011.[54] On 19 April 2012, it was announced that all internal systems were functioning, and the ship was entirely self-contained. Measurement of the ship's magnetic field and centre of gravity were performed before sea trials began.[55]

The ship is operated in a STOBAR configuration, with a 14.3° bow ski-jump ramp and three arrestor wires on the stern of the angled deck. The ship can carry more than 30 aircraft, with an air wing composed of MiG-29K/Sea Harrier fixed wing aircraft and Kamov-31, Kamov-28, Sea King, ALH-Dhruv and Chetak helicopters. The maximum take-off length for the MiG-29K on the carrier is between 160–180 metres.[8] The MiG-29K swing role fighter is the main offensive platform. It has a range of over 700 nautical miles (nm), which can be extended to over 1,900 nm with aerial refueling; and its weapons include anti-ship missiles, beyond-visual-range missiles, guided bombs and rockets.[8]

The superstructure profile of the Admiral Gorshkov platform can accommodate powerful planar or phased array radarsystems with the "billboard style" antennae, which was first observed on the United States Navy's USS Long Beach, along with extensive command and control facilities to conduct an aerial campaign. An extensive revamp of sensors was carried out, and long range air-surveillance radars and advanced electronic warfare suites were fitted. These enable the maintenance of a surveillance bubble of over 500 km around the ship.[8] The ship does not have a close in weapon system (CIWS), which will be added during its first scheduled refit.[56][57] By 2017, the carrier will be armed with the Barak 8 air-defence missile system, which has a 6-70 km strike range.[58]

The hull design is based on the Admiral Gorshkov launched in 1982, but it will be larger with a full load displacement. The conversion plans for the aircraft carrier involved all the armament, including the P-500 Bazalt cruise missile launchers and the four Antey Kinzhal surface-to-air missile launchers fitted on the front, to be removed to make way for a 14.3º bow ski-jump. Two restraining stands were fitted, allowing combat aircraft to reach full power before making a ski jump-assisted short take-off, but the carrier can launch only one aircraft at a time. Under the modernisation plan, the 20-ton capacity elevator beside the ship's island superstructure was unchanged, but the aft lift was enlarged and its lift capacity increased to 30 tons. Three arresting gears were fitted on the aft part of the angled deck. Navigation and carrier-landing aids were added to support fixed-wing "short take-off but arrested recovery" (STOBAR) operations including the LAK optical-landing system.[8][59]

The eight boilers were removed and converted to take diesel fuel utilizing LSHSD instead of furnace fuel oil, each providing a steam capacity of 100 tonnes per hour.[60] Modern oil-water separators as well as a sewage treatment plant were incorporated to meet international standards. Six new Italian Wärtsilä 1.5 MW diesel generators, a Global Marine communications system, Sperry Bridgemaster navigation radar, a new telephone exchange, new data link and an IFF Mk XI system were added. It has improved hotel services with new water-producing plants as well as York International refrigeration and air conditioning, and a new galley together with improved domestic services and accommodation for 10 female officers.[59]

The combat systems on board the carrier are controlled by LESORUB-E, the computer-aided action information system. It gathers data from the ship’s sensors and data links and creates comprehensive situation awareness. The CCS MK II communication complex is installed for external communications and the Link II tactical data system enables integration into the Indian Navy’s network-centric operations. Modern launch and recovery systems are installed for handling different aircraft - the LUNA landing system for Mig-29Ks and the DAPS Landing system for Sea Harriers. The Resistor-E automated air-traffic control system has been installed, which provides assistance during approach, landing and short range navigation down to a distance of 30 meters short of flight deck to the pilots. Along with various other sub-systems, it provides navigation and flight data to ship-borne aircraft operating at long distances from the carrier. [8][58]

The official expected life span of the ship is 40 years, and is unlikely to require any major repair work for at least a decade.[61][62] On completion of the modernisation, over 70% of the ship and her equipment will be new and the remainder will have been refurbished.[59] Sevmash Shipyard, which upgraded the carrier, will provide warranty servicing including maintenance for the next 20 years.[63]

Sea trials and commissioning[edit]

First sea trials[edit]

Russia was scheduled to hand over Vikramaditya to India on 4 December 2012,[64] with sea trials scheduled to begin on 29 May 2012.[65] The sea trials in fact began on 8 June. The ship sailed out for pre-delivery trials from the berth of the Sevmash shipyard in Russia's northern city of Severodvinsk. These trials were to include landing and take-off of fighter jets from the deck of the carrier.[66][67][68]

On 17 September 2012, malfunctions were detected during trials. According to official report, seven out of eight steam boilers of the propulsion machinery were out of order. Because of this, the deadline of the hand over this ship to the Indian Navy was postponed again until October 2013.[69] Later investigation has determined that the cause for the engine failure was due to poor workmanship and supervision.[70] The Gorshkov and other ships of the 1143.4 class had a history of multiple boiler failures,[71] however Russian shipbuilders claimed that the source of the problem was the low-grade Chinese-made firebricks that were used in the boiler insulation instead of asbestos.[72]

Second sea trials[edit]

On 3 July 2013, Igor Sevastyanov, deputy head of Russia's state arms exporter Rosoboronexport, announced that the warship had departed for sea trials with a mix of Russian and Indian crew.[73] On 28 July 2013, it was reported thatVikramaditya had successfully completed her sea trials and was able to reach her maximum speed of 32 knots. She then proceeded to the White Sea for aviation trials,[19] which were carried out by Russia's Northern Fleet aviation and completed in September 2013.[20][74] Aircraft and helicopters flew around and over the ship to check the performance of its radar, air defence, communication and control systems, and MiG specialists praised the ski-jump ramp.[75]

The sea trials lasted three months, and the ship demonstrated excellent seaworthiness and manoeuvrability. In total, the ship sailed for 19,500 miles during both the trials, and 778 flights were performed from its deck by aircraft and helicopters.[75]During the second sea trial, it sailed for 8,600 miles, of which 1,700 miles were under the command of the ship's Indian captain Commodore Suraj Berry.[76]

Surveillance by NATO[edit]

When the trials were ongoing, a Norwegian P-3 Orion aircraft observed Vikramaditya. While in international waters,[77] it flew close to the ship to take photographs, and also dropped sonobuoys to record the ship's acoustic signature. The Norwegian aircraft left the area when a Russian Mig-29 arrived. A Norwegian ship was also seen to observe Vikramaditya.[77]


She was formally commissioned on 16 November 2013 at a ceremony held at Severodvinsk, Russia.[21] The ceremony was attended by Indian defence minister A.K. Antony and the Russian deputy prime minister Dmitry Rogozin. The ship is expected to begin patrolling the Indian ocean by early 2014.[78]

Service history[edit]

After commissioning, the carrier began a continuous 26-day journey of 10,212 nautical miles to its homeport at INS Kadamba,Karwar, from Severodvinsk on 27 November 2013, with a short stopover in Lisbon.[14][79] It is under the command of Commodore Suraj Berry, who is her first Indian captain.[75] Apart from her Indian crew, she also carried 177 Russian specialists from Sevmash, who will remain on board for one year, as part of the 20-year post-warranty services contract with the shipyard. During the journey, it encountered a storm in the Barents Sea where she linked up with her escorts frigate INSTrikand and fleet tanker INS Deepak.[80] The group was escorted by the Royal Navy frigate Monmouth while passing through the English Channel,[81] and was joined by destroyer INS Delhi near Gibraltar.[14]

The flotilla sailed in the Mediterranean sea, crossed the Suez Canal[76][82] and entered the Arabian Sea near the Gulf of Aden on 1 January 2014. It was received nearly 1,200 nautical miles (2,200 km) away from Indian shores by a large flotilla of the Western fleet,[83] which was composed of the aircraft carrier INS Viraat, two Delhi-class destroyers including INS Mumbai, three Talwar-class frigates, the frigate INS Godavari, and a couple of offshore patrol vessels including INS Subhadra.[14] The event was significant as the Indian Navy was operating two aircraft carriers simultaneously for the first time in 20 years.[84]After conducting basic sea exercises with the fleet,[85] it reached Karwar on 7 January 2014.[86][87][88]

Navy pilots of INAS 303 "Black Panthers" operating the MiG-29K practiced carrier operations at the Shore Based Test Facility(SBTF) in INS Hansa, Panaji. The first aircraft piloted by an Indian Navy pilot landed on the carrier on 8 February 2014.[89]Since then, the pilots and air controllers have been certified for operating the MiG-29K fighters from the carrier deck, including night landings. The carrier's air wing will consist of 16 MiG-29Ks including four KUB trainers, six airborne early warning and control (AEW&C) Kamov Ka-31 and Kamov Ka-28 anti-submarine warfare (ASW) helicopters.[58]

In May 2014, the carrier was declared operationally deployed along with its embarked air group comprising Mig-29Ks and had taken part in a war game conducted by the Western Naval Command.[90][91] Wikipedia
