INS Nipat continuing towards Karachi, locked on to the Kemari oil storage tanks of the port from 14 nautical miles (26 km) south of the harbour. It fired two missiles at the tanks.
One of the missiles misfired, while the other hit the fuel tanks, which were burnt and destroyed, causing heavy loss.
The task force then withdrew back towards Mumbai. The operation Trident was also noted for introducing the first ship launched missiles in the region, to the war.
Operation Trident was considered an enormous success for the Indian Navy with no casualties or damage to the Indian task group, which returned safely back to Indian ports.
The success of this operation prompted another successful attack on Karachi on 8 December 1971, known as Operation Python.
