Way to go, it's range is 120km na??

It can go upto 100 km for now. But we are keeping the range capped at 90+km and working on getting better accuracy at this range. Once that has been achieved a longer range would be desirable. Increasing range isn't a huge problem, but increasing range along with high accuracy and all the while keeping the system light and very mobile is the challenge. One step at a time, we will get there.Way to go, it's range is 120km na??
We are working on some new solid propellents. These new solid propellents will give out more specific thrust for same weight. This way we will be able to increase the range without any change in the design. There are some indications that this very rocket can reach 150kms with newer propellents.Some browser issues on my end.

What about warhead weight? 300mm caliber rockets have ~250kg warheads.We are working on some new solid propellents. These new solid propellents will give out more specific thrust for same weight.

everything remaining same, higher specific thrust propellent can allow a higher range or you can increase the warhead size to maintain the same range.What about warhead weight? 300mm caliber rockets have ~250kg warheads.
Exactly. As far as I can tell two new fuel types are under development. One is a boron based fuel producing very high energy to be used primarily in powering the SFDR and the other is a fuel derived out of the CL-20.We are working on some new solid propellents.

This CL-20 derivative has been under development for sometime now and AFAIK, they do have a breakthru. This new propellent will even make our tank rounds more powerful.Exactly.

I believe the Arjun tank's Thermobaric round uses that fuel. There were some problems reported on impact activation of the CL-20, ARDE and HEMRL were worked together to stabilise it and make it safer. They have worked out the problem and now working on readying it for mass production.This CL-20 derivative has been under development for sometime now and AFAIK, they do have a breakthru.

<30 mSome say less than 50m
Both assumptions are wrong. How is it physically possible for XRSAM to be based on astra which is a 160kg missile.From DRDO's website :
XRSAM-IAF :
Lab : Defence Research & Development Laboratory (DRDL)
Technology Cluster : Missiles and Strategic Systems (MSS)
Long Range Surface to Air Missile Weapon System for the Indian Air Force. IAF has projected a requirement to induct Long Range Surface to Air Missile System to neutralise Aircrafts at Extended Ranges of 250km , Sea Skimming Anti-Ship Missiles (AShM) , AWACS at ranges of 350km, Stealth Fighters and Ballistic Missile in the terminal stage. The entire system shall be designed for transportability. IAF has accepted the configuration as shown below.

So the XR-SAM basically a Astra MK-2 with a Barak-8 ER like booster. Why the insistence on IAF ? Is the Navy version going to be different ?

I thought the XR-SAM would be based on the SFDR not the Astra Mk-2 :

They even had drawings out of the ground based version of the SFDR with boosters. Or maybe this is the testing rig for ground based testing, who knows. It would be a shame if we never make a SAM version of the SFDR.

Astra Mk-1 is 160 kg, we don't know the weight of the Mk-2. But we do know the Mk-2 is going to be significantly longer ranged, that is the rationale behind the development. The Mk-1 will also increase its range with time, DRDO chief said so himself. But the Mk-1 will have a shorter range that the Mk-2. It would be reasonable to assume the Mk-2 would be heavier.Both assumptions are wrong. How is it physically possible for XRSAM to be based on astra which is a 160kg missile.
Yes. It does seem to be the case.SFDR is a propulsion TD program with Russia. XRSAM was conceived before the trials of SFDR. It will take time for TD programs to evolve into something meaningful.
That thing is a bit big to engage a maneuvering fighter, don't you think ? But then the Akash is even fatter. The AAD currently has a range of 300 km. So is the booster going to add barely 60 km or range ? A little too small an improvement for a big booster it seems.We expected XRSAM to morph tech developed for BMD program mainly AAD missile.
DRDO website compresses pics and takes them out of their proper aspect ratio. @hellbent posted better resized pics on D. F. I.Why does the booster look too big? bad resizing is it?
Only difference is duel pulse motor. how long and heavier can it be?. Lets take example of NGARM which is already tested and has a duel pulse motor. Its on the same airframe design as Astra. Maybe a bit longer.Astra Mk-1 is 160 kg, we don't know the weight of the Mk-2. But we do know the Mk-2 is going to be significantly longer ranged, that is the rationale behind the development.

Nothing is too big to engage a fighter. Look at what we are getting from Russia.That thing is a bit big to engage a maneuvering fighter, don't you think ? But the Akash is even fatter.

I thought we were going to get a multi tube pulse detonation engine for the Astra Mk-2. PDEs are more efficient(and infinitely more complex) with increasing number to tubes. It is not confirmed if we are getting one of the multi tubes but we've had prototyping and testing of the engines done already.Only difference is duel pulse motor. how long and heavier can it be?.

True, those missiles are massive.Nothing is too big to engage a fighter. Look at what we are getting from Russia.
Possible. But given the fin configuration of the second stage I am inclined to believe its a Astra Mk-2. Time will tell I guess.Akash NG maybe.
Don't think so because it specifically says XRSAM-IAF. Could be for SMART or SR-NASMWe have a hot launch system for naval AD under development. The Barak-8/ER uses cold launch. This is for a new missile. Dare I say its for the XR-SAM. If so we have our own analogue to the US naval Aegis defence system coming up.
IN will want its own version. Maybe not now but they will want one soon enough.Don't think so because it specifically says XRSAM-IAF.
It says launch system for a naval AD. Those two aren't AD. It could be for the Astra based SR-SAM.Could be for SMART or SR-NASM
