Operation Trident


During the Indo-Pakistani War of 1971, The minesweeper PNS Muhafiz was tasked to patrol the approaches to port of Karachi. To do so it was deployed on the inner cordon.

Late that evening on 4 December 1971, around 70 miles south of Karachi, the INS Veer detected a large Pakistan Navy target, later identified as the Muhafiz on patrol to its north. Veer launched a single SS-N-2 Styx missile on the target, sinking Muhafiz.[6] It was later learned that at 23:30 the Muhafiz was hit by Styx missiles, and sank in the Indian Ocean at about 23:35.

Other vessels of the Indian Navy strike group sank the Pakistan Navy destroyer, PNS Khaibar and the merchant ship Venus Challenger (carrying navy personnel and ammunition for Pakistan),[6] and caused irreparable damage to the destroyer PNS Shah Jahan.
