IAF to get Next Generation Hardened Aircraft Shelters 

The IAF now has a thumbs up to build 108 present day shelters to house fighter aircrfats in forward territories on India's northern outskirts when China has increase movement in the Tibet Autonomous Region, which neglects Arunachal Pradesh, Himachal Pradesh, Uttarakhand, Sikkim and Ladakh.

The Union Cabinet had recently allocated about Rs 5,500 crore for the project to build the Next Generation Hardened Aircraft Shelters (NGHAS)

NGHAS are specialised structures comprising layers of reinforced concrete, sand and steel. They can protect aircraft from direct hits by a 2,000-pound bomb.

Majority of these solidified safe houses will be intended to house the Russian made Su-30 MKi – the backbone of IAF's warriors. 
Earlier IAF did not had defensive shelters to keep the Su-30Mki. NGHAS are not accessible for even the restricted quantities of aircraft that is available with the Service,"

IAF bases in the western sector have “blast pens”, which are supposed to protect aircraft from the effects of blasts in case of an attack. However, they can't give the protection as that of NGHAS
