No i didn't went there personally i've just gathered the information from official Sources.
So the ambiguity still exists regarding the number of aircrafts parked there, however the command structure of these squadrons resides there.
even if they are flying all over Pakistan they have to land back to their home base. so it means they all would be at same base after job.
Will need to calculate the probability of all the aircrafts landing at short time intervals so all the aircraft inventory is present at the base at a certain time of a certain day. And then factor in that India missile command will be sitting with trigger in hand to deploy a missile strike at that time.
In any case, its doubtful that all the strength of F-16's are present at base all the time, due to:
1. Ops Zarb e Azab
2. Exercises and Training
3. Detachments deployed at other locations
Its also reported that Pakistan has an underground hangar facility at Mushaf Airbase. Apart from this PAF uses hardened hangars made from concrete which can reduce damage to aircraft.
i also considered the same point about GHQ's but i feel hesitate to trigger this issue. it's also a matter of cocern but f-16s are back bone of PAF. these assets worth millions of dollars.
I had skimmed through 6 pages first and then gave a reply. Out of those 6 pages, only 1 page worth of postings can be considered the type of replies you expected, the rest of posts were trolling.
You should hesitate to trigger this issue,not because this issue is will not guarantee sensible replies but because it will be an open invitation to trolling again. Also you should have a clear idea now about deployments in peace and war time. Mobile Commands, Underground shelters, safe houses etc are at disposable of High Command.
If F-16's are millions of $$$ then KRL, POF, HIT, PAC and many other installations are Billions of $$$ worth and top brass of GHQ is priceless as decades of command and operations experience cannot be weighed in money. .
Lastly, there are no limits for being paranoid.
