Happy Independence Day


Wishing all Indians around the world a very Happy Independence Day. As India gears up to celebrate its 67th anniversary of Independence Day, and I feel proud to share that India's first indigenous aircraft carrier to be launched on Monday 12th of August 2013.! making an entry into a select club of countries capable of designing and building a carrier of this size and capability. As a part of prestigious project Vikrant class (formerly Project 71 Air Defence Ship (ADS) or Indigenous Aircraft Carrier (IAC)) which includes a class of two aircraft carriers being built for the Indian Navy. The two vessels are the largest warships and the first aircraft carriers to be designed and built in India. They are being built by Cochin Shipyard Limited. 

INS VIKRANT:
The first launched INS Vikrant has its flight deck is over twice the size of a football field, its power unit can light up the entire Kochi city and the cabling is enough to cover the distance between the city and Delhi. INS Vikrant, India's first indigenous aircraft carrier (IAC), to be launched today, is the biggest warship to be built in the country. It will also mark India's entry into a select club of countries capable of designing and building a carrier of this size.

The first ship of the class, INS Vikrant, displaces about 40,000 metric tons (39,000 long tons), is 262 metres (860 ft) long and has a tailored air group of up to thirty aircraft. The IAC-I features aSTOBAR (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 will fulfill theairborne early warning (AEW) role and the Sea King will provide anti-submarine warfare (ASW) capability.

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

The next entry is of 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.

INS VISHAL:
Design stage for INS Vishal (IAC-II) has begun, which is being undertaken by the navy’s 'Naval Design Bureau'. 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. 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 carrier is expected to enter service by 2025. On 1 August 2013 Vice Admiral RK Dhowan, while talking about the detailed study underway on the IAC-II project, said that nuclear propulsion was also being considered.
