Notes: Recently, Indigenous Aircraft Carrier (IAC) Vikrant successfully accomplished its maiden sea voyage. It is under a series of trial currently. 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. The name Vikrant means "courageous" and the motto of the ship is "Jayema Sam Yudhi Sprdhah", which is taken from Rigveda and can be translated as "I defeat those who fight against me".
