The Vikrant class aircraft carriers (formerly, the Project 71 "Air Defence Ship" (ADS)) are the first aircraft carriers of the Indian Navy to be designed and built in India. They are being built by Cochin Shipyard Limited (CSL).
The Vikrant class carriers will be the largest warships built by CSL. Work on the lead vessel of the class started in 2008, and the keel was laid in February 2009. Eighty percent of works on the carrier will be completed before its launch in 2010.[1] The first carrier of the class was expected to enter service by 2012,[2] but was delayed by a year reportedly due to the inability of Russia to supply the AB/A grade steel. This led to SAIL creating facilities to manufacture the steel in India.[3] In August 2009 the military purchasing publication Defence Industry Daily reported that the in-service date had slipped to at least 2015.
The early warning sensors and anti-aircraft missile capability of the first aircraft carrier is likely to be similar to that of the Kolkata class destroyers. CSL expects the Navy to place the order for the second carrier of the class 2010, and work is planned to begin in 2010.
History
India announced in 1989, a plan to replace the aging British-built carriers with two new 28,000 ton aircraft carriers. The first vessel was to replace the Vikrant, which was set to decommission in early 1997. Construction was to start at the Cochin Shipyard (CSL) in 1993 after the Indian Naval Design Organisation had translated this design study into a production model. In 2001, CSL released a graphic showing the 32,000-ton STOBAR (Short Take-Off But Arrested Recovery) design with a pronounced ski jump.[4] Though the proposal to build a 20,000 ton Air Defence Ship (ADS) had been in the pipeline since the early 1990s, it received formal government approval only in January 2003. By that time, the vessel had doubled in displacement, to a 37,500 ton warship that would carry jet fighters like the MiG-29K and not the Sea Harriers as first planned. In August 2006 the Chief of Naval Staff Admiral Arun Prakash stated that the designation for the vessel had been changed from Air Defence Ship (ADS) to Indigenous Aircraft Carrier (IAC). The misnomer ADS was adopted by the navy to ward off objections to the Navy going in for an aircraft carrier, especially by the IAF when the SU-30s were being acquired.
The design and construction of a carrier is a technical complexity which far outstrips any such challenge faced hitherto by the Indian Navy. The earlier planned displacement of 37,000 tons was increased to 40,000 tons due to design changes. The length of the ship also increased from 252 metres (827 ft) to 260 metres (853 ft).[5]
Design
The first carrier will feature a ski-jump in STOBAR (Short Take-Off But Arrested Recovery) configuration. The deck is designed to enable aircraft such as the MiG-29 and smaller to operate from the carrier.[6]
The Vikrant class is designed to deploy up to 40 aircraft, primarily the Mikoyan MiG-29K and the HAL Tejas Mark 2, including 10 Kamov Ka-31 or HAL Dhruv helicopters.
The naval version of HAL Tejas is hoped to be ready by the time INS Vikrant is commissioned.
Status
The keel for the lead vessel of the class, INS Vikrant, was laid by the defence minister A.K Antony at the Cochin Shipyard on 28 February 2009.[7][8] The ship will use modular construction. A total of 874 blocks will be joined together to speed up the building process. By the time the keel was laid, 423 blocks weighing over 8,000 tons, were completed.[9]
The vessel will be launched in 2010 when it would have completed some 20,000 tonnes, including the hull, as it cannot be launched at a higher displacement from the building bay. After about a year’s development in the refit dock, it will be launched again when all major components and everything underwater would be in place. Only outfitting would then remain. As per the CCS (Cabinet Committee on Security) plan, sea trials were initially planned to commence in 2013, with the ship to be commissioned in 2014.[10]
The order for the second aircraft carrier in the series is expected to be placed by 2010. The second carrier is planned to be inducted into the Indian Navy by 2017.[11] The second aircraft carrier is said to be of higher tonnage of above 50,000 tons and will utilise steam catapults. A 65,000-tonne IAC-II is on the drawing board. ‘‘It will be much bigger and capable of operating fighters, AEW (airborne early-warning) aircraft, tankers etc,’’ Admiral Verma said.[12][13]
Ships in class
Name | Pennant | Tonnage | Laid down | Launched | Sea trials | Commissioning | Details |
---|---|---|---|---|---|---|---|
INS Vikrant | 40,000 | Feb 2009 | Mid 2011 | 2013 | 2014[14] | Conventional-powered STOBAR carrier | |
INS Vishal | 50,000 | Oct 2010 | 2012 | 2015 | 2017[15] | Conventional-powered CATOBAR carrier |
Aircraft
IAC1 will operate a mix of MiG-29K and HAL Tejas.On 18 January 2010,it was reported that India and Russia were close to signing a deal for 29 Mig 29k fighters to operate from IAC1.[16]In addition,the navy signed a deal for six naval HAL Tejas.[17]
IAC2 could have a CATOBAR layout, because IN showed interest in the new US Electromagnetic Aircraft Launch System .[18] Among the five aircraft for which the Indian Navy has sent Requests for Information (RFI) are the F-35C, the carrier-based variant of the F-35 Lightning II , the F/A-18E/F Superhornet (made by Boeing for the US Navy), Eurofighter Typhoon (EADS supported by a European consortium), Sukhoi for Sukhoi Su-33, SAAB for Sea Gripen (version of Gripen adapted for carrier operations) and France’s Dassault Aviation for the Rafale.
India’s biggest military hardware supplier, Russia, which was asked for information on the Sukhoi Su-33, has opted out of the race saying it is phasing out the plane, a navy source told The Telegraph.
The Indian Navy had originally not sent an RFI to Sweden’s SAAB but the company expressed interest and was sent a request for the naval variant of the Gripen JAS 39.
