Operation Trident was an offensive operation launched by the Indian Navy on Pakistan's port city of Karachi during the Indo-Pakistani War of 1971. Operation Trident saw the first use of anti-ship missiles in combat in the region. The operation was conducted on the night of 4–5 December and inflicted heavy damage on Pakistani vessels and facilities. While India suffered no losses, Pakistan lost a minesweeper, a destroyer, a cargo vessel carrying ammunition, and fuel storage tanks in Karachi. Another destroyer was also badly damaged and eventually scrapped. India celebrates its Navy Day annually on 4 December to mark this operation. Trident was followed up by Operation Python three days later.
Operation Python, a follow-up to Operation Trident, was the code name of a naval attack launched on West Pakistan's port city of Karachi by the Indian Navy during the Indo-Pakistani War of 1971. After the first attack during Operation Trident on the Port of Karachi, Pakistan stepped up aerial surveillance of its coast as the presence of large Indian Navy ships gave the impression that another attack was being planned. Pakistani warships attempted to outsmart the Indian Navy by mingling with merchant shipping. To counter these moves, Operation Python was launched on the night of 8/9 December 1971. A strike group consisting of one missile boat and two frigates attacked the group of ships off the coast of Karachi. While India suffered no losses, Pakistani fleet tanker PNS Dacca was damaged beyond repair, and the Kemari Oil Storage facility was lost. Two other foreign ships stationed in Karachi were also sunk during the attack.
