Looking at this promotional video of Barak MX system by IAI:
It has three missiles:
1. Barak MRAD: Single pulse 35 kms range.
2. Barak ERAD : Dual pulse 70 km range.
3. Barak ER: 150 kms range, ERAD with booster.
Looking at our Akash-NG program. It's earlier range with dual-pulse motor was quoted around 70. Now in recent DRDO screenshot they are quoting 30/35 km range. So looks like with Akash NG program we're mimicking Barak MX program. We also have both single and dual pulse variants of Akash NG.
If we put a booster onto the dual pulse variant then we'll have our own desi alternative of Barak ER. Maybe, the much talked about ERSAM(with 150 kms range) is Akash NG dual pulse variant with a booster.
So even if MRSAM project didn't gave us IP, it at least gave us knowledge how to develop a super effective indigenous solution.
