During the Indo-Pakistani War of 1971, the Indian Navy's 25th Missile Boat Squadron, operating Vidyut-class missile boats, played a crucial role in the devastating Indian attacks on Karachi in December 1971. The two key operations in which these vessels played an active role were Operation Trident and Operation Python. Indian attacks destroyed half of the Pakistani Navy and most of Pakistan's naval fuel reserves in the port's fuel storage tanks which cleared the way for the decisive victory of the Indian Armed Forces.
