In the eventuality of a war, Indian forces believe that the proposed Parma Valley airfield can be effectively used to conduct aerial bombings to block Chinese or China-Pak aggression and prevent reinforcements for Chinese troops. Currently India has airfields like Fuk Che, Nyoma and Daulat Beg Oldie near the Line of Actual Control in Ladakh region.
Most importantly, unlike other airfields bordering Line of Actual Control (de facto India-China border), Parma Valley is at distance where Indian Armed Forces will be beyond the sight of Chinese forces.
Experts says Parma Valley may prove to be the most important strategic airfield in the region for the armed forces. Air Marshal A K Singh, Former Commander in Chief, Indian Air Force says, "Opening up of an airfield in Parma Valley, certainly bordering the Western Highway of China, would mean that some of the weapons which hitherto cannot be deployed, would be in a position to be deployed, and would then be threat to a movement on that particular highway.
Now, with India opening up the valley, China has no legs to stand down because it is within Indian territory and India will be well within its right to (not exactly to threaten because India does not threaten any country) but certainly to exert its influence, should there be some mischief going on in that area."
Western Highway connects Xinjiang in China's southwest with Tibet after which it branches off near Quilanaldi and becomes the Karakoram Highway. This is the way through which Pakistan and China could launch a joint offensive against India.
