As India celebrates its 75th Independence Day 15 August 2021, the Southern Naval Command (SNC) offered a sneak peek into the engineering marvel that is INS Vikrant, the country's first indigenous aircraft carrier (IAC). The largest and most complex warship built in the country, opened its 'doors' in Kochi after its maiden sea trial successfully concluded on 8 August 2021.


  1. It demonstrates the Indian Navy's capability to design and oversee the construction of the most complex of warships, as also the capability of our ship-builders and industries to successfully execute such a large and complex ship-building project.
  2. All the major electrical industries including BHEL have contributed to the construction of this ship.
  3. The power generated in the ship is used for electrical systems including the radar system, communications, navigation, propulsion power generation, steering, air conditioning, food storage, safety related systems, medical systems among others.
  4. The construction of the IAC was a major challenge to the design team of the Cochin Shipyard Limited (CSL).
  5. Currently, the CSL is the only shipyard in the country that could undertake repairs of major aircraft carriers.
  6. The aircraft carrier, with more than 76 per cent indigenous components, is expected to be commissioned into the Indian Navy by August next year after it completes the aviation trials.
  7. Vikrant has a top speed of around 28 knots and cruising speed of 18 knots with an endurance of about 7,500 nautical miles. The ship can accommodate an assortment of fixed-wing and rotary aircraft.
