New Delhi. 12 August 2016. The Indian Air Force (IAF) has so far activated four Advanced Landing Grounds (ALGs) at Ziro, Along, Mechuka and Walong in Arunachal Pradesh.

The ALGs and aviation infrastructure in the North-East are being developed to improve air connectivity in the region. These ALGs would act as transportation hubs during peace time and in case of contingencies like road closure, landslides, conflicts and war like situations the ALGs would act as launch bases for support of troops as well as replenishment of supplies.
