NGHAS Next Generation Hardened Air Shelters
The existing HAS were meant to accomodate Mig-21s and smaller planes. So they can't accomodate Sukhois
2015: News trickles in about plans for NGHAS to accomodate Sukhois

At all airbases across India you can see new HAS(even before NGHAS approved) being built since last two/three years . These HAS seem wide enough to accommodate Su-30s. They resemble the DRDO HAS in above picture.
Each airbase has just two of these. So not meant to accommodate entire squadron.
Su-30 are 22m long and 15m wide.
New HAS seem to be 30mx18m

In NE region both HAS are build side by side. NE regions lack HAS for even normal Migs or have open blast pens. Western bases are crowded with little room for expansion.

Interestingly these new HAS can be found at even faraway bases even in South India.
A good writeup on HAS and how HAS have been made ineffective by modern PGM/Cruise Missiles.

So even before NGHAS starts we have been building HAS to accommodate Sukhois albeit at much smaller scale. In all not more than 30-40 such new HAS at present exist.
One such finished HAS with camouflage facing China.
