Navy’s dream carrier packs a punch
PICTURE a scenario: It is the dead of the night over the Indian Ocean. A MiG 29-K fighter of the Indian Navy has just completed a mission and heads back to the sea-borne aircraft carrier INS Vikramaditya some 400 km away. If the pilot communicates with the warship over the radio, he could reveal his and the ship’s position to enemy radio interceptors, resulting in immediate retaliation. Alternatively, he uses the onboard computer and ‘locks on’ to the radar complex onboard the Vikramaditya.
The radar complex has a system called the ‘Resistor-E’ which guides the fighter jet virtually in autopilot mode and makes it reach just 30 metres away from the warship, thence the pilot takes over for a final landing — all the while maintaining what naval aviators call a ‘zip-lip’ procedure or total radio silence. It will be the first-ever such facility onboard an Indian naval warship, propelling it into the very exclusive club of nations like the US, France and Russia to have similar capacities. In naval parlance, the ‘Resistor-E’ is a microwave landing system and precision approach radar and beacon. In a lay term, it is like an instrument-aided landing system (ILS) installed at airports, which allow operations in all-weather conditions. The system of the warship is even more sophisticated as there is no margin of error on a moving ship. This is just one of the several examples of what the aircraft carrier will add in terms of capacities and the latest technologies to the Navy’s war-fighting abilities.
Loaded with an array of sensors, radars, communication aids and on-deck fighter planes equipped with state-of-the-art missiles, the Vikramaditya is like a swift-sailing behemoth, capable of detecting threats within 500 km of air space. Once airborne, the fighter jets will widen the arc of dominance with an ability to hit at targets in air, on land and on the sea surface while helicopters specialising in anti-submarine warfare will pick out under-sea threats.
The heart of the operational network that infuses life into the warship’s combat systems is its advanced combat management system called ‘LESORUB-E’. It gathers data from the ship’s sensors, radars and data links (including imagery available from the fighter jets, helicopters, UAV’s and the naval satellite launched in August this year) to provide the commanders a comprehensive tactical picture and then take a decision. “It generates continuous air, surface and under-sea scenario and evaluates threat for warfare functions,” the Navy said, explaining how it would change the dynamics.
A senior naval officer in New Delhi explained: “These abilities are so far unparalleled in the Indian Navy. It will enhance our foothold in the immediate maritime neighbourhood and in the international and foreign waters.”
Enabling the 44,500-tonne warship in its swiftness, are eight boilers built by Russian supplier Baltizky Zavod, which produce steam at high pressure, almost 1.5 times more than any existing Indian naval ship. A very high level of automation requires minimal human intervention. The boilers power four enormous propellers, each greater in diameter than twice the height of an average male and generate 2,00,000 shaft horse power. The warship has an arrangement system to enable it to carry out operations unscathed even in a nuclear fallout zone.
Lethal MiG 29-K
One of the biggest additions will be MiG-29Ks that have ‘four times’ greater capacity than the existing naval fighters — the British-origin Sea Harriers. The planes can fly for 1,300 km and double the distance after mid-air refuelling using the IAF’s IL-78. As per a fact-sheet by Russia, work to develop the sea version of the widely acclaimed MiG-29 (used by air forces, including IAF) started in 2004. The ‘K’ in MiG-29K stands for ‘Korabelny’, meaning ‘ship borne’ in Russian. The planes have already been delivered and are stationed at the naval airbase in Goa.
The aircraft are powered by the new RD-33MK engines that have augmented thrust and the fuel capacity has been increased by over 50 per cent over the traditional MiG-29 aircraft. It will carry the Zhuk-ME radar which provides a longer detection range of air targets. It can carry guided air-to-air missiles, including medium-range missiles, with active radar homing warheads and R-73E short-range attack missiles for close manoeuvring air combat. It can deploy Kh-31A and Kh-35A missiles with active radar homing heads.
Warship to carrier
Commissioned into the Soviet navy in 1987 as ‘Baku’, it was a warship carrying helicopters and vertical takeoff and landing fighters Yak 36 and 38. These were Soviet version of the Sea Harriers which India was already using in that era. It was a ship carrying long-range attack missiles, artillery guns and submarine warfare capability, but did not have a traditional flight deck. After the Soviet Union collapse, it was renamed ‘Admiral Gorshkov’ and was put to hibernation after its last sailing in 1995.
When it was offered to India in 1995, New Delhi was looking for a conventional aircraft carrier allowing powerful twin-engine fighters to operate. The refit involved degutting of wiring, equipment removal, refit and re-equipping the ship with new ‘ski jump’ that allowed fighter jets to take off and also have a set of three arrester wires which stall the plane when it lands.
Since fighter jets remain housed inside the belly of the ship, it needed installation of two lifts. Some 2,300 km of new electrical cabling was put and 2,500 tonnes of new steel plates were used to strengthen the outer hull. Fitment of reverse osmosis plants and new AC and refrigeration plants was also done. Sensors and equipment like long-range air surveillance radars and electronic warfare suite capable of detection and localisation of electronic emissions has transformed the ship into a modern platform. This was needed to operate aircraft, including MiG29K, Sea Harriers and Kamov 31, and Kamov 28, Sea King, ALH-Dhruv and Chetak helicopters.
The biggest challenge was the creation of a flight deck. It involved increasing the breadth at the flight deck; strengthening the area of arrested wires and runway; elongation of rear-end; and a new ‘ski jump’ at an elevation of 14 degrees.
Captain PVS Satish, Navy spokesperson, says: “The floating airfield has an overall length of about 284 metres and a maximum beam of about 60 metres — as much as three football fields put together. Standing about 20 storeys tall (from the keel to the highest point), the ship has 22 decks towering a height of 60 metres.”
A long journey
At its meeting on October 26, 1949, the Defence Minister’s Committee on Navy cleared the concept of India having two light carriers, each carrying a fighter squadron of 16 aircraft. The standing committee of Parliament cleared it on November 13, 1950, after Prime Minister Jawaharlal Nehru and Governor-General of India Lord Mountbatten pushed for it.
INS Vikrant, India’s first aircraft carrier (UK acquired), was commissioned in 1961. It was followed by INS Viraat in May 1987. This changed the game, with Sea Harriers then being top-of-the-line jets. India operated two carriers from 1987 till January 1997, when INS Vikrant was retired. It will be almost after 16 years that New Delhi will have two carriers.
