INS Vikrant, also known as Indigenous Aircraft Carrier 1 (IAC-1), is an aircraft carrier constructed by the Cochin Shipyard Limited (CSL) for the Indian Navy. It is the first aircraft carrier to be built in India. It is named ‘Vikrant’ as a tribute to India’s first aircraft carrier, Vikrant (R11). The name Vikrant means “courageous” in Sanskrit. The Indigenous design and construction of Aircraft Carrier by Indian Navy and Cochin Shipyard Ltd is a shining example in the Nation’s quest for ‘AatmaNirbhar Bharat’ and ‘Make in India Initiative’ with more than 76% indigenous content. This has led to growth in indigenous design and construction capabilities, besides development of large number of ancillary industries.
Vikrant is powered by four General Electric LM2500+ gas turbines 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 ship’s combat management system (CMS) was developed by Tata Power Strategic Engineering Division in collaboration with Weapon and Electronics System Engineering Establishment and MARS, Russia. It is the first CMS developed by a private company for the Indian Navy, and was handed over to the Navy on 28 March 2019. After the launch, Vikrant would be re-docked for the second phase of construction, in which the ship would be fitted with various weapons and sensors, and the propulsion system, flight deck and the aircraft complex would be integrated.
