I think this is a sign that China is getting serious and not just putting on a show. There would be little need to deploy JH7s otherwise, as they are very much the unglamorous workhorses of the PLAAF.
If the PLAAF was flexing for the cameras, they would be sent J16s. JH7s are for getting the job done while at the same time not placing anything too precious at higher risk.
As for air supremacy, well I don’t think the PLAAF will venture into Indian airspace in the event of combat, at least to start with.
The Chinese will focus on defence over Chinese airspace with fighters and SAMs complimenting each other while strikers and bombers spam cruise missiles form deep within Chinese airspace at Indian air bases, ground based early warning radar and other high value targets.
That puts the IAF in the impossible position of having to either pull back from most of its northern bases for fear of being obliterated on the ground, and gifting air dominance to China with a bow on top; or having to fight against overwhelming odds to try to get at Chinese bombers and strikers in Chinese airspace protected by layers of SAMs, AAA and having to fight through PLAAF fighter cap, which will almost certainly include J20s vectoring in from outside Tibet.
Forcing the IAF to fight over Tibet initially serves Chinese interests in multiple domains:
- it places the IAF at maximum disadvantage and allows the PLAAF to operate with home field advantage, which will more than offset any numerical and payload advantages the Indians enjoy due to geography.
- politically, it makes India the indisputable aggressor
- it makes it harder for India to BS away their losses as the Chinese would have actual physical evidence of shot down IAF planes and captured pilots.
Once China has cut the IAF down to size and reduced its northern air bases to rubble, the PLAAF could then counter-attack into Indian airspace and take the fight to them and start to systematically destroy the helpless IA ground forces and any dual use pieces of infrastructure it feels necessary.
At that point it would not need to even fight very hard to achieve and maintain air dominance over huge sways of northern India.
I beg to pardon, but from the photograph, we see more Air to Ground platforms than Air to Air. Unless we think that JH-7 and H-6 will be used to counter Indian's elements on air, I believe that those in Khasgar will be used to flattened Indian's ground elements instead. For H-6 has transform into missile trucks rather than a bomber, I think China's massage is clear. All India land is within their target range if India plan to raise the tension and go into hot war option. Because they can target India's nuclear sites in the south of India territory from Tibet air space.
