	On the night of 8/9 December 1971, at 10:00 pm [[Pakistan Standard Time]] (PKT), in rough seas, a small strike group consisting of the missile boat {{INS\|Vinash\|K85\|6}}, equipped with four [[P-15 Termit\|Styx]] missiles, and two multipurpose frigates, {{INS\|Talwar\|F140\|6}} and {{INS\|Trishul\|F143\|6}}, approached [[Manora, Karachi\|Manora]], a peninsula south of the Port of Karachi. During their voyage, a Pakistani [[Patrol boat\|patrol vessel]] was encountered and sunk. The Indian Navy's official historian, [[Vice Admiral]] [[Gulab Mohanlal Hiranandani\|Hiranandani]] in his book ''Transition to Triumph'', mentioned that while the group approached Karachi, ''Trishul'''s [[electronic surveillance]] revealed that the [[radar]] there had stopped rotating and was directed straight at the group, confirming that it had been detected.{{Sfn\|Hiranandani\|2000\|p=199}}		On the night of 8/9 December 1971, at 10:00 pm [[Pakistan Standard Time]] (PKT), in rough seas, a small strike group consisting of the missile boat {{INS\|Vinash\|K85\|6}}, equipped with four [[P-15 Termit\|Styx]] missiles, and two multipurpose frigates, {{INS\|Talwar\|F140\|6}} and {{INS\|Trishul\|F143\|6}}, approached [[Manora, Karachi\|Manora]], a peninsula south of the Port of Karachi.

	Around 11.00 pm (PKT), the group detected a batch of ships at a distance of {{convert\|12\|nmi\|abbr=on}}. ''Vinash'' immediately fired all four of its missiles, the first of which struck the fuel tanks at the Kemari Oil Farm causing a heavy explosion. Another missile hit and sank the [[~~Panamanians~~\|Panamanian]] fuel tanker SS ''Gulf Star''. The third and fourth missiles hit the Pakistani Navy fleet tanker PNS Dacca and the [[United Kingdom\|British]] [[merchant ~~vessel~~]] SS ''Harmattan''.

	Around 11.00 pm (PKT), the group detected a batch of ships at a distance of {{convert\|12\|nmi\|abbr=on}}. ''Vinash'' immediately fired all four of its missiles, the first of which struck the fuel tanks at the Kemari Oil Farm causing a heavy explosion. Another missile hit and sank the [[Panama\|Panamanian]] fuel tanker SS ''Gulf Star''. The third and fourth missiles hit the Pakistani Navy fleet tanker [[PNS Dacca]] and the [[Merchant Navy (United Kingdom)\|British merchant ship]] SS ''Harmattan''. ''Dacca'' was damaged beyond repair, while ''Harmattan'' sank. As ''Vinash'' had now expended all of its missiles, the group immediately withdrew to the nearest Indian port.{{Sfn\|Hiranandani\|2000\|pp=201–202}}		Around 11.00 pm (PKT), the group detected a batch of ships at a distance of {{convert\|12\|nmi\|abbr=on}}.
