That story on the PAF website is.........just a story.
Okha was a FOB (Forward Operating Base) for the IN in 1971 There was only a NLO (Naval Liaision Officer) of Lt.Cmdr. rank posted there to liaise with the local civil authorities. Only the Missile Boats could use the Harbor because of Size/Water Depth limitations since Okha was a local
Fishing Harbor. Okha was operationalised to provide a re-fuelling
back-up for the Missile Boats which were designed by the Soviet Union only for Coastal Defence with an Operational Range of approx. 100 N.M. at full speed, which would not allow the OSA Boats to sail un-refuelled to Karachi and back. In the event, the OSAs were towed by the Frigates to conserve fuel, before being let loose for the attack.
This attack impressed the incredulous Soviet Navy who just could not believe that the OSAs could be used as such. And the Soviet Union Navy Supremo, Adm. Sergei Gorshkov had an abiding respect for the IN subsequently. The man who authored and pushed the IN plan of attack at Karachi had a "Karachi Connection"......Adm. S.M.Nanda. He was employed in Karachi Port Trust when WW II broke out. He joined the RIN as an RINVR Officer finding himself as CNS of the IN in 1971. He knew Karachi like the back of his hand. He has written about the plan of attack in his memoirs titled "The Man who bombed Karachi".
Do take a look at any Map/Google Earth to see how Karachi Harbor is located with particular attention to the Harbor Entrance. The Entrance is common with Bin Qasim Port and is constrained by the size and depths of the approach channel. IN's approach was two-pronged: to bottle up the PN Fleet in the Harbor and hit the POL capacity in Karachi which directly impacted Pakistan's ability to carry on the conflict. This was in addition to the Blockade enforced by IN Ships on the High Seas which cut off re-supply of Ammunition and other War Material which was steadily depleting.
This attack on Okha was insignificant and contrasts with the damage wrought on Karachi which was the MOB (Main Operating Base) for the PN. Apart from the extensive damage caused to the Oil-Tank Farm at Keamari, Karachi there was havoc in Karachi Harbor. Our Senior Co-Member Niaz Sahab was there and was part of the team that courageously fought the fires at the Tank-Farm. In consequence of the Karachi Raids, The Pakistani Fleet pulled back into harbor and did not venture forth later, the Warships were 'de-ammunitioned' to reduce the damage in case of subsequent raids which were expected by the PN. The CNS PN desperately sought assistance from the PAF at the time; but was told "it happens Old Boy" and simply fobbed-off.Then PIA and Karachi Flying Club aircraft were roped in to do an Air-Search for casualties and survivors of the attack at sea.
It is likely that somebody may now well "regurgitate" another story of a "Huge Attack" on Porbandar (
btw, how many here know where it is?) in 1965 from a PN website. Porbandar had no Naval Presence, but was shelled by PN ships. Since most shells turned out to be duds (they were recovered then by the IA/IN BDS teams later) they were found to be marked IOF (Indian Ordnance Factories) 1940 stock. The Railway Station Waiting-Room roof was blown off and
1 cow died......which was the extent of the damage.
