With this, India joins a select group of countries capable of building such a vessel.
Other countries capable of building a similar ship are the US, the UK, Russia and France.Monday's launch of INS Vikrant marks the end of the first phase of its construction.
The ship will be then re-docked for outfitting and further construction.
The ship, which will have a length of 260m (850ft) and a breadth of 60m, has been built at the shipyard in Cochin.
It was designed and manufactured locally, using high grade steel made by a state-owned steel company.
Vice-Admiral RK Dhowan of India's navy has described the launch as the "crowning glory" of the navy's programme to produce vessels on home soil.
