The Night Indian Navy Destroyed Karachi. On the night of December 4, 1971, the Indian Navy carried out one of the most daring and decisive naval attacks in modern military history. In this video, we break down Operation Trident, the secret mission where Indian Navy’s Osa-class missile boats — INS Nirghat, INS Nipat, and INS Veer — launched a surprise attack on Karachi Port, the heart of Pakistan Navy operations. Within a single night, multiple Pakistani naval vessels were destroyed, ammunition ships were sunk, and Karachi’s oil storage tanks were set ablaze — burning for seven straight days.
