China has also built up plenty of airfields (extensions to existing ones and new one planned) along with plenty of army bases. All would be targeted by Indian artillery and missiles during initial exchange. This isn't the reason to not build them. You can still intercept attacks and they offer a layer of resistance. The logic of not deploying forwards would be like saying there's no point making the armour of a MBT thicker because that new outer layer would only just get damaged once it is attacked.
Same reason as China building islands in SCS even though US can easily destroy the military equipment and positions on them. They are all there as resistance and a basis to launch initial attacks as well. A chess player who wouldn't advance any pawns in an opening is only doing themselves a disservice. Those pawns are there to be lost but do play an important part in your overall strategy. How well they will work however is entirely dependent on the forces, how well they are used, and what the adversary has and does.
Well as far as I know the only Chinese airbase close to the border in in Nyingchi But the rest is out of reach of Indian Artillery's except maybe for Brahmo and long range MLRS. But of course they are all vulnerable to air attack. But they will get shot as soon as they cross the border. since China has good radar coverage all along the border. And air defence missile are spread along the border. The main bases are all in Xinjiang and Qinghai Hotan, Kashgar and Golmud. forward air base are Lhasa Gonggar, Shigatze, Ngari Gunsa roughly 150 km to the border. Smerch MLRS which India have has a range of 100-135 Km
China building air base in SCS act like a tripwire and improve china's situation awareness and snooping and air and naval activity of the foe Yes it is static and in theory it can be attacked But by building in triangle formation each of the airbase can provide mutual support I am not sure if it is easy to overcome them
The Kashgar airbase, approximately 475km from Eastern Ladakh, is the farthest from Indian borders. The recent
is seen as a direct strategic manoeuvre against India.
The dual-use airbase with 3,200m runway has seen apron expansions, new large hangars possibly for H-6 bombers and airborne early warning (AEW) aircraft and 12x hardened aircraft shelters for fighters.
Hotan Airbase
Though the Hotan airbase is a dual-use airport, recent developments indicate it has been converted to military use only.
The airbase has seen new AEW aircraft deployment along with J-8 and J-11 aircraft. New UAV hangars with CH-4 UAVs have been observed after the Doklam standoff.
Large construction has been seen at this airbase for troops and improvement in the ammunition point located there. Recent reports suggest that PLAAF J-20 stealth aircraft were deployed here, although just for two days.
Ngari Gunsa Airbase
The airbase barely 125km from Indian borders has seen small detachments of fighters and helicopters. The airbase has been used for various aircraft trials since it has one of the longest runways of almost 4.5km.
Recently, during a medical exercise, a dummy patient was carried from Ngari town in a helicopter to this airport and further sent to Qionglai in a Y-9 air ambulance of the PLAAF.
Shigatse Airbase
This dual-use airport was converted to an airbase with a stoppage of civil flights after the Doklam standoff.
This airport has seen a new deployment of UAVs with a brand new airstrip for them. New movable hangars have been observed at the eastern end of the airbase.
New aprons for helicopters and a new hangar for possible AEW aircraft are also observe
