The problem for Feng was that he was running out of airbases. That might seem surprising until one considered that the Tibetan plateau, because of its very high altitude, is not conducive for fighter operations as sea-level airbases are. This has to do with the thinner density air at these airbases that forces fighters to use ultra-long take-off lengths to allow operations or much reduced payloads over shorter lengths. Chinese sea-level airbases were simply too far out from the battlefields.
This reduced the net effect of the numerical superiority enjoyed by the PLAAF against the IAF. The latter was effectively using its plethora of sea-level airbases on the southern side of the Himalayas to beat the low density Chinese fighter forces over Tibet into submission.
The airborne tanker force was the only support option in such cases. And while the Indians were easily doubling the endurances for their fighter patrols because of the close proximity between the airbases and the AO, it was taking a flight of J-11s three tanker refueling operations simply to bring the aircraft to the AO and allow it to maintain a decent length patrol. So how do you concentrate forces between such widely displaced airbases and light tanker forces?
And cruise-missiles were not the answer. Not the permanent answer, at any rate. They had to be launched by standoff aircraft and now that the Indians had gained dominance over the skies of southern Tibet, they were thinning out the slow moving cruise-missile barrages with air-to-air missiles before the former could reach their targets. So while some missiles from each barrage were getting through, it was creating an attrition rate far lower than anticipated by Feng and his staff in all pre-war simulations.
Feng put down the fork for the final time and looked out the large glass walls of the dining hall where he could see the last vestiges of orange-pink skies as the sun went below the horizon.
He wiped his hands and got up from the table, invoking looks from several officers eating their food. Feng was lost in his own thoughts. As he walked over to glass walls and stared up, he could see the darkening skies above and the reflection of the dining room behind him in the glass of the windows. He touched the windows and felt the cold outside as the first snowfall of the night was beginning.
He smiled and brought his hands behind his back in the formal stance but continued to stare out. He saw two J-7s lighting up their afterburners as they took to the skies in a paired formation. The fighters quickly switched off the afterburners and disappeared into the starry night sky…
The Indians were not big on the use of cruise-missiles the way his own side was, Feng thought again.
The problem with this configuration was that each fighter could only carry one of the supersonic missiles during a single sortie. So that meant a flight of several Su-30s configured for the launch role could launch at best perhaps a half-dozen missiles at a time. Better still, doing so required them to move precious heavy fighters away from the air-dominance role and into the strike fighter role at a time when they could least afford it.
By comparison, Feng could deploy six cruise-missiles from a single H-6 and not have to divert his J-11 force into the task. The Brahmos ALCM was a very high-speed missile but with low range and endurance compared with true long-range cruise-missiles. Their subsonic Nirbhay missile was intended to fill this role but had not entered service yet, which was fortunate for Feng and the other PLAAF planners. The Nirbhay, when matured, would become the equivalent of the Chinese CJ-10 Long-Sword GLCMs. The Brahmos ALCM on the other hand was a purely tactical SEAD-specific missile and had been used as such by the Indians.
Then there was the availability of the missiles. The Brahmos ALCM was new to the Indian inventory and had been acquired only a year ago. Production rates in India did not compare well with China and so they had only a few missiles on hand when this war had started.
