In the 2nd video he said we can neutralise aerial threat aircraft by QRSAM/Akash NG at 30-50km. That is consistent with past defexpo information.
For drones high power mw or laser burning is used.

Still not sure about Akash-NG range. In the recent Def Expo they just showed the range as 35kms(IIRC). Akash-NG even with a single pulse motor can easily cover 50kms range(it's bigger than QRSAM). With twin pulse(as all the reports say that it has), we're looking at a true range of between 80 to 120kms.

It's both longer/thicker and heavier than MRSAM. And MRSAM'S range is anywhere between 70 to 110 kms. What's your take on Akash-NG range? Why the hell is DRDO so much downplaying its range:unsure:

I am not sure either though I am not sure heavy weight being the indication it can go really long, if they take the dual pulse version then it will definitely be alternative to MRSAM. Akash system was dedicated as a short range sam , hence the upto 50km confidence level make sense for that. They have MRSam for mid rang 70-100km and after that xrsam is in development, seems army may also be getting it. Akash ng i think canister system & possibly composite use lesser wight missiles are what got improved from original 25km non-canister akash. So as multilayer ad go, 30/40km QRSAM & 50km NG would complement well.

Heavier weight is because it's longer and thicker than Barak-8. That itself means more propellant/bigger motor. There is no way Akash-NG airframe is going to be less advance than MRSAMs'. Thus more range is a given if we use dual-pulse motor.

XRSAM project will apparently will have two missiles: ERSAM and XRSAM.

Earlier ERSAM was supposed to be MRSAM with additional booster with 150 to 200kms range. Now they may go with Akash-NG with booster to achieve that goal.

XRSAM could be AAD or AD-1 derived. Not too sure on this. This is going to be the 350 kms range AWACS killer missile.

There is no comparison between weight of Akash and Akash-NG. Akash is ramjet powered missile that weighs 700+ kilos. Akash-NG is going to be around 300 to 350kgs thanks to dual-pulse rocket motor. But still more heavy than 275kg Barak-8. QRSAM is around 4.4m and weighs 270kgs.

Akash-NG is the future of our air-defence. Can't wait to have it in active service.

How do you come up with this conclusion? Do you have the exact weight and dimensions of Akash-NG to compare with other systems?

It's fundamentally wrong to evaluate a SAM based on range alone. These systems are developed based on requirements to fill air defense gaps.

Yeah that is certain, akash ng launcher & mrsam launcher system easily vet that, 6 vs 8 formation. I mean for use it is possible IAF gets mrsam while army use akash ng which in turn need to match area coverage & objective (point defense vs long range attack interceptor), should that be the army specification. My guess is these systems complement each others role. So in that case, for akash ng 40-50 km bubble would be very good, even if it can do job well beyond that range too. Test either happened or very soon, there was banshee drone procurement notice specific for this very recently, Nov-Dec.

XRSAm will probably have similar missile iteration like s-400, multiple interceptors. They finalised config of arming & detonating mech of this system (which goes into every missile really). That project has a curious name.

Ashwin, I speak or guess only when there is enough proof. People guessed Akash-NG's dimensions when DRDL launched a tender about its cannister.

Also, Indranil has already spilled the beans, if you haven't noticed:

Very nice find(y)

Actually, Akash-NG is for both IAF and IA.

IAF version:

This could be the army version(my guess) as it is mobile:

designs of broadband compact and rugged antennas are presented for launcher applications. These antennas can be fabricated from a single block of stainless steel or any other metal, which can withstand high shock and temperature of 1000ºC when
subjected to rocket plumes inside launcher.

If this is true, then its close to Barak 8. The requirement must be different on warhead weight and altitude. Thus the overall weight and range difference. It will definitely has~50km at least as max range.
