INS Vikrant (from Sanskrit vikrānta, "courageous") was a Majestic-class aircraft carrier of the Indian Navy. The ship was laid down as HMS Hercules for the British Royal Navy during World War II, but was put on hold when the war ended. India purchased the incomplete carrier in 1957, and construction was completed in 1961. Vikrant was commissioned as the first aircraft carrier of the Indian Navy and played a key role in enforcing the naval blockade of East Pakistan during the Indo-Pakistani War of 1971
