Now, IAF is watching Chinese bases, sure of matching air power. India is closely tracking Chinese air bases in Tibet and Xinjiang, which witnessed an initial build-up of fighters, bombers, drones and other aircraft as border tensions escalated on the ground, but is not too perturbed about air combat power along the LAC, with IAF seen to pack a solid operational punch. There has been “no major or fresh infusion of assets” by the People’s Liberation Army-Air Force at Hotan and Kashgar in Xinjiang as well as Gargunsa, Lhasa-Gonggar and Shigatse airbases, some of which also function as civilian airfields, said defence sources. But the Indian Army and IAF, as part of their “total combat potential” deployed along the 3,488-km LAC after border skirmishes in Ladakh, moved forward surface-to-air missiles and other such systems to tackle aerial threats.
