Lol yeah that is the probable explanation for that observation
I was just thinking when PN has all four Oliver Perry Class frigates they will need a helo to go with it the obvious choice for PN would be additional Z9C, PN operates 6 of them for use with the F22P frigates and they have been testing them off the OHP frigates too so I would guess that PN should add another six Z9C helos to its fleet
Then we have the same situation if we go for four more FFG from China which means another 6 helos required
It would mean the helo fleet for PN could include 18 x Z9C helos for use with 12 frigates, I would like to see the latter helos being the upgrade Z9D which can carry light anti-ship missiles as apposed to just one torpedo
And finally operating of UAV from Pakstani frigates has been on going for a few years expansion in this field would be good as usually only a single helo is carried on PN vessals when that lands back for refuelling or re-arming the UAV can be the eyes in the sky maintaining surveillance
Here's pics of PN Z9C operating off PNS Alamgir previously USS McInerney
