Agni & Prithvi Ballistic Missiles : News & Discussions

In June 2023, MIDHANI had produced >2.5 m rings made out of "TiTaN-31" alloy. The TiTaN-31 alloy's formula was produced by DMRL & productionized by MIDHANI. MIDHANI says that these rings were made for space applications.

By "space applications", they probably mean a satellite launch vehicle. This ring will probably be at the interstage of the launch vehicle & will house electronics, guidance, sensors & stage separation equipment.

Right now, India has 2 space launchers under development: NGLV & Veda. As we know now, the NGLV will have a uniform diameter of 5m. So, these rings were meant for Veda then.

We don't know much about the Veda. But we know that it will not have a uniform diameter. We also know that the Veda will get its stages from Indian ICBMs/SLBMs.

The largest of our ICBMs/SLBMs so far have a diameter ~2m. So, this 2.5m ring must be for a new stage of an upcoming ICBM or SLBM. So either A6 or K5.

In June/July 2024, ASL had released a tender for the fabrication of rubber seals & end support rings for A5, A1P & K5 missiles. Thanks @marich01 for this:

Notice the nomenclature "K5S1C". This probably means K5 missile-Stage 1-CRMC type solid stage. Here the inter diameter is shown as 2418mm or 2.418 m. This is the outer diameter of the CRMC. Therefore a 2.5 m interstage ring on this stage is very plausible.

@marich01 hypothesized some months ago that Veda is probably K5's 1st stage mated with A5's or K4's 2nd stage. I think he is right.
Bloody hell are they building R-39 Rif successor lol
 
Hopefully the next test is in due course, ie next year similar time frame to this years (March-April) ? with the special item of course. ;)

ASL is happy to show the new toy in the poster , more hint that the LRAShM is mostly for strategic asset , ie liquidating a carrier would be classified as equivalent to target a strategic asset. right ? Again ie, solely the LR-AShM version is another strategic asset & will operate under SFC?

The other part which the PIB statement alluded to, the missile can carry multiple kv so another offshoot with a different KV can play the part of a different conventional weapon system provided the Govt clears DRDO to develop one.

^ About LR-AShM being strategic or not, forgot that INS Tunir will be expanded to facilitate this system besides the usual inducted systems. so likely non strategic. Kinda rare given strategic nature of ASL projects, ignoring some composite stuff like making the LCA drop tank etc.

No mention of VL-SRSAM :(

Guys, I found something interesting.

Allow me to push this hypothesis further.

We got the dimensions for the carbon fiber re-enforced composite payload fairings of the VEDA launcher:

The 2nd one from the left is the VEDA's payload fairing. We knew that for some time. The manufacturer, LMW, calls it "payload fairing for defence":

469232797_617870560806740_148446454928114393_n.jpg

The payload fairing is 2m in diameter & 3m in height. This fairing can probably encapsulate either:
12-20 satellites of the IMS bus type or
4 sats of the I-1K bus type or
2 sats of I-2K bus type.

For satellite reference:
IMS bus: EMISAT, MicroSat, HySIS, SARAL etc.
I-1K bus: INSAT series, GSAT series, TES etc.
I-2K bus: INSAT series, GSAT series, RISAT series, CARTOSAT series etc.

Also, since the payload fairing is 2m is diameter (same as the A5) the VEDA can probably borrow the A5's MIRV-ed payload bus.

From what we know so far, we can reasonably expect the VEDA to be a 3-stage missile with a 2.5m CRMC 1st stage. 2nd & 3rd stage is likely borrowed from the A5. This combined with the A5's MIRV-ed bus, we have an Indian equivalent to the RS-24 Yars. They may call this missile A6.

Now the centerpiece technology of the VEDA is the 2.5m CRMC 1st stage. With the tender docs we have seen so far, I would argue this motor is a going to be derived from the K5 project.

Theoretically a missile of this class should have the range to reach the entirety of China, some parts of EU, Russia, Canada & USA when launched from India. Due to political reasons, it may not be declared as an ICBM. But make no mistake, this will be our 1st global nuclear strike weapon. It will be truly global when we acquire the ability to launch missiles of this class from our SSBNs.

This is unrelated but I also found a composite nose cap. Probably for an BM. Not sure which one:

VEDA 2nd stage is also 2.5m, its the third mirv bus stage V3C is 2m dia along with the payload fairing. Since DRDO only tested the mirv part only recently, we can expect much less number of tests that has happened so far aka on hand data is limited but likely a proven set of flight trial data. So it makes sense to use the mirv bus on VEDA too, we can get more data and then scale this up to fit mirv bus of future higher dia systems say from 2m dia class of A5 to 2.5 sized mirv bus stage ie increment.

The bottom green part in the veda model is entire 2.5m dia class and there are 2 stages there, hence I thought this part together could be used as a new system entirely aka K5 by sticking a single rv on top or making a bigger payload bus. A full single stage motor the size of those 2 stages together, ie instead of 2 motors of x length each say one single crmc of 2x length might give failure in the testing phase since it would be very high powerful and a longer burn duration. So even with precision mfg the chance of failure is high. So make 2 smaller stages, test and gather the tolerance limit for various parameter like max burn length, impulse, failure point etc. Then make a suitable longer stage motor once the scientific boundary conditions are established.

That is from the htcc panel test video of NDTV old clip 2012 , think that had the gyro pic yes.

What would be the future of A3 ? would it remain a tech demo, sort of ? to test mirv bus or other next gen tech ? wrt @hellbent post on this before
