IAC-1
Subject: Defence
Context: The Indigenous Aircraft Carrier (IAC) 1, which will be called INS Vikrant once it enters service with the Indian Navy about a year from now, started sea trials — one of the last phases of trials on Wednesday
Concept:
- The INS Vikramaditya, currently the Navy’s only aircraft carrier that was commissioned in 2013, started out as the Soviet-Russian Admiral Gorchakov.
- The country’s two earlier carriers, INS Vikrant and INS Viraat, were originally the British-built HMS Hercules and HMS Hermes before being commissioned into the Navy in 1961 and 1987 respectively.
- India’s earlier aircraft carriers were either built by the British or the Russians
IAC-1
- This is the first aircraft carrier designed and built in India. An aircraft carrier is one of the most potent marine assets for a nation, which enhances a Navy’s capability to travel far from its home shores to carry out air domination operations.
- An aircraft carrier generally leads as the capital ship of a carrier strike/battle group. As the carrier is a valuable and sometimes vulnerable target, it is usually escorted in the group by destroyers, missile cruisers, frigates, submarines, and supply ships.
- IAC-1 has been designed by the Indian Navy’s Directorate of Naval Design (DND), and is being built at Cochin Shipyard Limited (CSL), a public sector shipyard under the Ministry of Shipping.
- Only five or six nations currently have the capability of manufacturing an aircraft carrier It is considered to be one of the most advanced and complex battleships in the world.
- According to the Navy, over 76 per cent of the material and equipment on board IAC-1 is indigenous. This includes 23,000 tonnes of steel, 2,500 km of electric cables, 150 km of pipes, and 2,000 valves, and a wide range of finished products including rigid hull boats, galley equipment, air-conditioning and refrigeration plants, and steering gear.
- The warship will offer an “incomparable military instrument with its ability to project Air Power over long distances, including Air Interdiction, Anti-Surface Warfare, offensive and defensive Counter-Air, Airborne Anti-Submarine Warfare and Airborne Early Warning”.
- The Navy said that IAC-1 will be “the most potent sea-based asset”, which will operate the Russian-made MiG-29K fighter aircraft and Kamov-31 Air Early Warning Helicopters, both of which are already in use on the Vikramaditya.
- The new Vikrant will also operate the soon-to-be-inducted MH-60R Seahawk multirole helicopter manufactured by the American aerospace and defence company Lockheed Martin, and the Advanced Light Helicopter (ALH) built by Bengaluru-based Hindustan Aeronautics Ltd.
INS Vikrant
- INS Vikrant, a Majestic-class 19,500-tonne warship, was the name of India’s much-loved first aircraft carrier, a source of immense national pride over several decades of service before it was decommissioned in 1997
- . India acquired the Vikrant from the United Kingdom in 1961, and the carrier played a stellar role in the 1971 war with Pakistan that led to the birth of Bangladesh.
- The Vikrant was deployed in the Bay of Bengal, and its two air squadrons of Sea Hawk fighter jets and Alize surveillance aircraft were used in strikes on ports, merchant ships, and other targets, and to prevent Pakistani forces from escaping through maritime routes.
20+ years in making
1999: Project ‘P71’ to build Air Defence Ship (ADS) cleared
2003: Aircraft Carrier project gets government nod
2006: Navy says ADS changed to Indigenous Aircraft Carrier
2009: Keel laid
2011: Floated out of dry dock
2013: Launched
Nov 2020: Harbour and basin trials completed
Aug 2021: Sea trials begin
Next: Shipbuilder will continue sea trials over the next 6-7 months; then hand over IAC-1 to Navy for trials
Aug 2022: Expected to be commissioned. Trials of aircraft and component parts will follow.
Navy officials point out that even if India gives the IAC-2 project the go-ahead now, it will be over 10 years before the warship is commissioned.
