Agni & Prithvi Ballistic Missiles : News & Discussions

No that is written as A4 gas generator, the turbo gas generator they use inside canisters for ejecting the article, which is kinda odd given A4 is not yet visibly canisterised anywhere.

A5 integration on , lets hope its mirv test as well.

A4 tested

A successful launch of an Intermediate Range Ballistic Missile, Agni-4, was carried out from the Integrated Test Range in Chandipur, Odisha on September 06, 2024. The launch successfully validated all operational and technical parameters. It was conducted under the aegis of the Strategic Forces Command.

This is a missile from where we entered into new category of missiles. Where Agni III was a 48 ton missile with 3500 KM range, Agni V managed 4000 km with less than 20 ton of weight and gave us capability cover most geographical area of China. This enabled us to introduce new technologies including guidance in our old missiles and optimize their performance. We reduced the weight of Agni III to 23 tons later on.

Agni 3 is a different thing, its a 2 meter dia large case bonded solid motor which was the first development in its class within the country. There is one very good video with one of the scientist, actually armed forces person, who was involved with its development. Now with crmc stages its even next gen. And there is no telling what the bigger version is capable of. Building blocks are almost all ready.

A4 and A4 prime both are much less dia class and will serve as interesting land vectors.

That is true but tell me How Agni III is different. It has a bigger dia. because it was designed that way. What I emphasis was that it bought new technologies which later on went into other missiles. After Agni IV, Major breakthrough in technology was Agni I Prime. It had a very powerful composite motor , It is very fast and has has a long rage compared other missiles in weight class. It is very accurate and has a potential of conversion into LRASM. It was MIRV. Later on same technology went into Agni V to increase its range.

Imo, A4/5 were built on a solid foundation established by the naval K-15/4 missile family. Lighter composites and miniaturization was essential for the compact confines of sub VLS. The K-15 itself evolved into the Shaurya and eventually the Pralay.

The K-series was a separate program and, at one point, DRDO was even considering standardizing on the K-series, in both land and sub-launched strategic roles.

Sandeep Unnithan wrote a piece on this back in 2010 and now it's been put behind a paywall, all these years later!

I wish prithvi gets a new gen treatment. ALl other missiles from PATNA era are getting NG versions, even the slbm one too. What wrong did Prithvi do ? Liquid fuel lives matter. ;)

Anyway , a small gif , original source is DRDL , kinda would have posted the salvo one but these are classified stuff so :censored:

It already has. In the PDV. As a solid fuel missile, it probably wouldn't take much to turn it into an SRBM. Kinda like what the USN is doing with SM-6.

If it's not too much to ask, could you post any images (sanitised, of course) of the K4 emerging from the water?

The only pic/gif that exists shows the K4 nose cap motor pull it out the water before the first stage kicks in. Is that really the case or is it gas bubble (cannister in missile tube) like most other SLBMs?

Of course, hence they call it nose mounted booster probably

I think only the Russsians have used this kind of tech in practice for launching SLBMs. Is it safe given the nose cap sits right on top of the warhead fairing?

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:
1728147593816.png

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.
