India’s First Indigenous
Aircraft Carrier - INS Vikrant
Cochin
Shipyard Limited (CSL), the Country’s premier shipbuilding yard has been
mandated to build the indigenous Air Craft Carrier, for the Indian Navy. The
basic design of the Air Craft Carrier was carried out by the Indian Navy’s
Directorate of Naval Design (DND). The design was further developed into a
detailed design by the design team of Cochin Shipyard Limited.
DND has
successfully designed over 17 different classes of warships, to which around 90
ships have already been built within the country. Designing of the Vikrant, at
almost 40,000 tonnes speaks of the maturing of the
capabilities of DND and represents a feather in the cap of the designers
particularly as it is the first aircraft carrier of its size in the world with
some unique features such as Gas Turbine Propulsion
At the
launch, marking the end of Phase- I of the project, the imposing ramp of the
37,500 tonne Short Take off but Assisted Recovery
(STOBAR) Carrier boasted the indigenous design and build capabilities of the
country. The ship has attained its designed length of about 260 m and is almost
at its maximum breadth of 60 m. The main landing strip is ready. Over 80% of
the structure, containing about 2300 compartments has been fabricated, over 75%
has been erected, all the major machinery, such as the two LM2500 Gas Turbines
developing a total power of 80 MW, the diesel alternators capable of producing
about 24 MW and the main gear box have been fitted. Soon after Vikrant floated
perfectly upright, she was launched out into the Ernakulam Channel in a pontoon assisted
precision manoeuvre.
Vikrant was moved out of the building dock to be positioned in the refitting
dock where the next Phase of outfitting will be completed The Aircraft Carrier
would carry a complement of mix of fixed wing and rotary aircrafts in its
hanger.
The Aircraft
Carrier is a mini floating city, with a flight deck area covering the size of
two football fields. The length of cabling would be 2700 KM which, if laid end
to end would stretch from Kochi to Delhi . The ship would
have a complement of 1600 personnel.
Vikrant will
be capable of operating an aircraft mix of the Russian MiG-29K and LCA (Navy)
fighters being developed indigenously by HAL. Its helicopter component will
include the Kamov 31 and the indigenously developed ALH
helicopters. The ship’s ability to sense and control a large air space around
it will be enabled by modern C/D band Early Air Warning Radar, V/UHF Tactical
Air Navigational and Direction Finding systems, jamming capabilities over the expected
Electro Magnetic (EM) environment and Carrier Control Approach Radars to aid
air operations. Long
Range Surface to Air
Missile (LR SAM) systems with Multi-Function Radar (MFR) and Close- In Weapon System (CIWS) will form the
protective suite of the ship. All weapon systems onboard the carrier will be
integrated through an indigenous Combat Management System (CMS), being
manufactured by Tata Power systems. The ship’s integration with Navy’s Network
Centric Operations will provide force multiplication.
The steel
has come from SAIL’s plants in Rourkela in Orissa, Bokaro in Jharkandand Bhilai in Chattisgarh;
the Main Switch Board, steering gear and water tight hatches have been
manufactured by Larsen and Toubro in its plants in Mumbai and Talegaon;
the high capacity air conditioning and refrigeration systems have been
manufactured in Kirloskar’s plants in Pune; most pumps have been supplied by Best and Crompton,
Chennai; Bharat Heavy Engineering Limited (BHEL) is supplying the Integrated
Platform Management System (IPMS); the massive gear box is supplied by Elecon in Gujarat; the tens of thousands of
electrical cable is supplied by Nicco industries
in Kolkata; Kolkata is also where the ship’s anchor chain cable is
manufactured.
The launch
marks the end of the first phase of the construction of the carrier with nearly
75% of the vessel structure, including the ski-jump, in place. Vikrant will now enter the second
phase of construction which will see the outfitting of the ship, fitment of
various weapons and sensors, integration of the gigantic propulsion system and
integration of the aircraft complex (with the assistance of M/s NDB of Russia).
The ship will then undergo extensive trials before she is handed over to the
Indian Navy by around 2016-17.
The Ship is
designed to survive in the event of attack by nuclear, biological or chemical
weapons.
The project
was fraught with many challenges right from the special steel used in
construction to the fabrication and erection of the large blocks and lowering
of the huge main equipment. These challenges were overcome by the innovative
and creative workforce of CSL The shipyard has developed a number of weld
procedures and introduced automation to ensure quality of welding and increase
productivity. The yard has adopted techniques to increase production rates by
going in for grand assembly of blocks and pre-outfitting to the extent
possible.
Cochin Shipyard today is the best
performing shipyard in India .
The Shipyard had built and delivered over 90 ships since its inception. The
largest ship built in the Country has been constructed by CSL. In the last
decade the company has built and exported over 40 ships to International
owners.
The indigenous Aircraft Carrier
designed by DND is one of the most prestigious warship project of the Indian Navy. Indian Navy has
now changed the status from buyer’s navy to a builder’s navy.
