New INS VIkrant Photographs New Launch August 12th Shipyard Product

Proud to be Indian.

INS Vikrant to be launched on August 12 from Kochi shipyard. India to be the fifth country after the US, Russia, Britain and France to have the capability to build such vessels.

The Vikrant class (formerly Project 71 Air Defence Ship (ADS) or Indigenous Aircraft Carrier (IAC)) are a class of two aircraft carriers being built for the Indian Navy. The two vessels are being built by Cochin Shipyard Limited (CSL), they are the largest warships as well as the first aircraft carriers to be designed and built in India.

Preparations for building the lead vessel of the class started in 2008, and the keel was laid in February 2009. The carrier was floated out of its dry dock on 29 December 2011. The scale and complexity of the project caused problems which delayed the commencement and timeline of construction for the carrier. Technical difficulties, the huge cost of refitting the Russian-built carrier Admiral Gorshkov, and billions in cost overruns[6] has seen the lead vessel now entering service in 2017 rather than a previous in service date of 2014.

INS Vikrant

The first ship of the class, INS Vikrant, will displace about 40,000 metric tons (39,000 long tons), be 262 metres (860 ft) long and have a tailored air group of up to thirty aircraft. The IAC-I features a STOBAR (Short Take-Off But Arrested Recovery) configuration with a ski-jump. The deck is designed to enable aircraft such as the MiG-29K to operate from the carrier. It will deploy up to 20 fixed-wing aircraft, primarily the Mikoyan MiG-29K and the naval variant of the HAL Tejas Mark 2, besides carrying 10 Kamov Ka-31 or Westland Sea King helicopters. The Ka-31 fulfills the airborne early warning (AEW) role and the Sea King provides anti-submarine warfare (ASW) capability.

The carrier will be powered by four General Electric LM2500+ gas turbines on two shafts, generating over 80MW of power. The gearboxes for the carriers are designed and supplied by Elecon Engineering
INS Vishal

In April 2011, Admiral Nirmal Kumar Verma stated that construction of the second carrier was some years away as there were a number of higher spending priorities for the navy. The design of the second carrier features significant changes from Vikrant, like an increase in displacement to over 65,000 tons and using a steam-powered CATOBAR system to launch heavier aircraft like larger fighters, AEW (airborne early-warning) aircraft and mid-air refueling tankers.

Design stage for INS Vishal (IAC-II) has begun, which is being undertaken by the navy’s 'Naval Design Bureau'. The navy has decided not to seek outside help in preparing the design concept and implementation plans. The navy might later seek help from the Russian Design Bureau in order to integrate the Russian aircraft onto Vishal. IAC-II will be a flat-top carrier with a displacement of 65,000 tons, 25,000 tons more than Vikrant and will be having a CATOBAR system, unlike the STOBAR system on IAC-I.

Naval versions of Tejas, Sukhoi/HAL FGFA, Advanced Medium Combat Aircraft (AMCA) and the Rafale M fighter jets are likely to operate from the aircraft carrier. The navy evaluated the Electromagnetic Aircraft Launch System (EMALS), which is being used by the US Navy in their latest Gerald R. Ford-class aircraft carriers. General Atomics, the developer of the EMALS, was cleared by the US government to give a technical demonstration to Indian Navy officers, who were impressed by the new capabilities of the system. The EMALS enables launching varied aircraft including unmanned combat air vehicles (UCAV). The carrier is expected to enter service by 2025.
