Though it is a good news that PAF is getting 3~4 inflight refueling tankers, but the question is that refueling is done 40,000 ft, so if an a/c is topped up going EWNS there are so many airfields in between with JP4 & Jt-A fuel. There only need would be when ferrying a/c from China or US. Maybe 2 such a/c would be sufficint.
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.
