India’s first indigenous aircraft carrier (IAC) Vikrant set sail on October 24 for the second sea trials, ahead of its planned induction into the Indian Navy by August next year.

The 40,000-tonne aircraft carrier, the largest and most complex warship to be built in India, successfully completed a five-day maiden sea voyage in August. Following the first sea trials, the Navy had said that the performance of key systems of the warship was found to be satisfactory.

The warship has been built by Cochin Shipyard Limited (CSL).

Aircraft carriers in India

• An aircraft carrier is a warship designed to support and operate aircraft, engaged in attacks on targets afloat or ashore and to undertake sustained operations in support of other forces. 

• An aircraft carrier is central to the operational requirements and fleet doctrine of the Indian Navy and is the only means of ensuring air defence of sea. 

• INS Vikrant, India’s first aircraft carrier was acquired from Great Britain and commissioned on March 4, 1961. INS Vikrant was a Majestic class CATOBAR (Catapult Assisted Take Off but Arrested Recovery) carrier and operated Sea Hawk fighters, Alize (Anti-Submarine Warfare) aircraft and Seaking helicopters. 

• India next acquired HMS Hermes, a Centaur class STOVL (Short Take-off and Vertical Landing) carrier  and a veteran of the Falkland War. INS Viraat was commissioned on May 12, 1987 as India’s second aircraft carrier and India’s first STOVL carrier operating the Sea Harrier aircraft. 

• Soon after the acquisition of INS Viraat, INS Vikrant was also converted from a CATOBAR carrier to a STOVL carrier.

• INS Vikramaditya was commissioned on November 16, 2013. INS Vikramaditya is a Kiev class aircraft carrier which was commissioned by Russian Navy in 1987 under the name Baku. It was later renamed as Admiral Gorshkov and last sailed in 1995 in Russia, before being offered to India. The 44,500 tonne warship has a length of 284 metres.

• INS Vikrant was decommissioned in January 1997.

• INS Viraat was decommissioned in 2017. 

• At present, India has only one aircraft carrier — INS Vikramaditya.

• The IAC is 262 metres long, 62 metres wide and it has a height of 59 metres. 

• Its construction began in 2009.

• The ship has been designed with a very high degree of automation for machinery operation, ship navigation and survivability. 

• The warship, which will operate MiG-29K fighter jets, Kamov-31 helicopters, MH-60R multi-role helicopters, has over 2,300 compartments, designed for a crew of around 1,700 people, including specialised cabins to accommodate women officers. 

• It would 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.
