Let me build a scenario, expert advice needed...
An f-16, is airborne, with max payload of weapons, and only essential fuel so that it can get over Lahore, from Sargodha. Here, over Lahore, its refueled by a refueler orbiting over Lahore. Now F-16 can continue East, for a deep strike mission inside Indian territory. It can deliver its weapon payload to the target and get back to Lahore, with fuel level dropping. Again, it is refuelled over Lahore, and then continue to Sargodha.
Aerial refuelling allows, fighter aircarft to takeoff, with max weapon payload, and just essential fuel, so that it can fly to a tanker.
Similarly, once AWACS, will be acquired by Sweden, by PAF, these airborne radars can remain in air for extended period of time, by repeated aerial refuelling.
I think, it is wrong to assume that tankers are only benefecial for long distance ferry mission, over Karakuram/Himalaya Ranges.
Two problems:
1.An tanker in air over forward location becomes an indicator that something is coming. It means tankers have to be based interior of the country and I am not sure if it wise to take off from say Lahore,travel back, fill up and then be on the way.
2. IAF will ALWAYS hit tankers and AWACS first. They are high value and easier targets.
Tankers are used if you guarantee air supremacy in the area they operate.For PAF it will assist in longer loitering time over it's airspace.
