The recent rebirth of Vikrant, India’s first aircraft carrier, de-commissioned on January 31, 1997, marks a special feather in indigenous defence capabilities- this being the first ever aircraft carrier to be designed by the Directorate of Naval Design of the Indian Navy, the first warship to be built by Cochin Shipyard Limited and the first warship to be built entirely using indigenously produced steel.
The construction of the ship is a truly pan Indian effort with active participation of private and public enterprises. The steel has come from SAIL’s plants in Raurkela in Orissa, Bokaro in Jharkand and 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 Kokatta;
Kolkatta is also where the ship’s anchor chain cable is manufactured. 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. Design of this prestigious ship has been undertaken by the Directorate of Naval Design (DND) of the Indian Navy. Created in 1956 as the Corps of Naval Constructors, to realise the dream of being a builder’s Navy through indigenisation, DND has successfully designed over 17 different classes of warships, to which around 90 ships have already been built within the country.
The Delhi class destroyers, with a displacement of about 7000 tonnes, were the biggest warships designed by DND so far. 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. The seamless hull and smooth lines of the ship stand as testimony to the high production standards of Cochin Shipyard Limited (CSL). CSL, a mini Ratna PSU, has earned a reputation for quality construction and timely delivery. Till now, CSL had the distinction of building the largest ship in India i.e., 93,500 tonne Aframax tankers. However, this complex integrated construction project enabled by a Rs 200 crore infrastructure augmentation plan involving large cranes, workshops and heavy duty machinery has seen the shipyard maturing into a competent warship builder. 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.At the recent 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.
