INS Vikrant,First Indigenous Aircraft Career ,Indian Navy
INS Vikrant (IAC-I) is the first aircraft carrier built in India and the first Vikrant-class aircraft carrier built by Cochin Shipyard (CSL) for the Indian Navy.
It is the first indigenous aircraft career in the new “Vikrant-Class” of surface warships and has seen construction begin in 2009. The carrier was floated out of its dry dock on 29 December 2011 and was launched in 2013. Construction is expected to be completed by 2016 and the ship is due to be commissioned in late 2018. The project cost has escalated dramatically to ₹19341 crore (US$2.9 billion) as of 2014.
AT the time of launch in July 2013,it was said that about 83% of the fabrication work and 75% of the construction work was complete. He said that 90% of the body work of the aircraft carrier had been designed and made in India, about 50% of the propulsion system, and about 30% of its weaponry.Also the ship would be equipped with a long range missile system with multi-function radar and a close-in weapon system (CIWS).After the launch, Vikrant was re-docked for the second phase of construction, in which the ship will be fitted with various weapons and sensors, and the propulsion system, flight deck and the aircraft complex will be integrated.
The vikrant-class-carrier is 262 metres (860 ft) long and 60 metres (200 ft) wide, and displaces about 40,000 metric tons (39,000 long tons). It features a Short Take-Off But Arrested Recovery (STOBAR) configuration with a ski-jump.
Design concepts of the new indigenous Aircraft Carrier emerged in 2001 to which project was formally acknowledged by the Indian government in 2003 with proper funding to see it through.The vessel class was bestowed the name of “Vikrant”.
Propulsion and Performance
Vikrant is powered by four General Electric LM2500+ gas turbine on two shafts,generating over 80 megawatts (110,000 hp) of power.The gearboxes for the carriers were designed and supplied by Elecon Engineering.The Vikrant has a crew capacity of 1,400 (including air crew).The aircraft carrier moves in the oceans with the speed of 28 knots (52km/h) and have the range of 8000 nautical miles (15,000 km).
Sensors and Avionics
INS Vikrant has integrated with Selex RAN-40L AESA radar and EL/M-2248 MF-STAR AESA(Multi-Function Surveillance, Track And Guidance Radar) which is used for long range maritime air surveillance and early warning. The radar uses a fully solid state active phased array antenna and capable of tracking and detecting air targets like aircraft or drones up to 400 km away.
It is also equipped with C/D Early air-warning radar used primarily for the long-range detection of its targets, i.e., allowing defences to be alerted as early as possible before the intruder reaches its target, giving the air defences the maximum time in which to operate
The INS Vikrant is being armed by latest arms which includes 4x Otobreda 76 mm (3in) naval artillery gun which have a high rate of fire and availability of specialised ammunition make it well-suited to varied roles such as short-range anti-missile point defence, anti-aircraft, anti-surface, and ground support. Specialised ammunition includes armour piercing, incendiary, directed fragmentation effects, and a guided round marketed as capable of destroying manoeuvring anti-ship missiles
Vikrant is also armed with Barak 1 & Barak 8 Surface-to-air missile launchers (2×32 cells VLS) which are specially used to defend against any type of airborne threat including aircraft,helicopters,anti-ship missiles ,UAVs,cruise missile and combat jets.
The AK-630 fully automatic naval close-in weapon system based on a six-barreled 30 mm rotary cannon also defend the Vikrant against anti-ship missiles and other precision guided weapons.
Aircraft Carried on the Deck
The deck is designed to enable aircraft such as the MiG-29K to operate from the carrier. It is expected to carry an air group of up to thirty aircraft, which will include up to 30 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 the airborne early warning (AEW) role and the Sea King will provide anti-submarine warfare (ASW) capability.It also carried HAL Dhruv on the deck.

Other Aircraft carrier in Vikrant Class-The INS Vishal
There are basiclly two ships in the Vikrant Class-The INS vikrant as the lead ship and her sister,The INS Vishal.However,while the Vikrant will be completed as a 40,000 ton design with ski-ramp deck,it was announced in August of 2012 that Vishal will sport a more conventional “Flat Top” deck arrangement with Catapult Launching Facilities known as “CATOBAR” Catapult-Assisted Take-Off Barrier Arrested Recovery.With this design initiative,the Indian Navy will be allowed to launch larger and heavier fixed-wing aircraft such as Airborne Early Warning (AEW) types which are not possible with the limited STOBAR configuration-drastically broadening the Indian Navy’s power in local waters.The changes to the Vishal will make it a 65,000 ton vessel with an all new flight deck.
