After the incident, "Mangro" sailed to Pakistan under the command of Lieutenant-Commander Shamim Khalid and reported to its base in Karachi. On 22 November 1971, "Mangro" was deployed under the command of Lieutenant-Commander Shamim to patrol off the Arabian Sea, and eventually detected the Indian Navy's armada that was sent to attack Karachi. No attack was carried out as both nations had not officially declared war, but she tracked the squadron.
