its a mix.

reliance aquired kemlock which is a vadodara based company who collabed with the NAL to develop aerospace grade fibres.

they also have their own R&D division that's investing in this tech and the hazira plant is specifically focused on high grade/aerospace grade which is t700/t800/t1000. Im sure they will be also be producing t300 but the higher end is the main goal(repeatedly emphasized as well) with the 20k tpa being reached around 2027-29(depends on demand and the speed of opening up new lines).

They can also expand beyond that quite easily since hazira is being planned in a modular way and even if they need a new site they can simply reuse designs which will cut down time by a lot.

So if we are still importing T300 than the T700 for this SLBM comes from a foreign country most likely Japan.

We probably does produce T300 but failed to make T700/800 & upward..... Japanese are producing T1100 in scale since 2014.


Muj pvt sector..... Screw giri & more Screw giri at triple the cost.

this guy is beyond stupid, like what? does he not research what hes blabbering about? man i really hate opening twitter cause you have to deal with ragebaiters who entire point is to farm engagement.

Reliance have indegenous production being planned at quite high capacity. They also have an inherent advantage compared to Toray in the sense that they have complete control over the precursor material production. China might also enjoy the same advantage since their refineries are almost all state owned but reliance has it completely within the company itself.

love the AI generated profile pic as well. man i really cant listen to twitards or god forbid xtards

What grade ?

Specs roughly corresponds to T800 class or lower.

Polyacrylonitrile based Carbon fiber manufacturing Technology | CSIR - NAL | Govt. Of India

Pilot plant scale employing Polyacrylonitrile based Carbon fiber manufacturing Technology having integrated continuous processes at rates suitable for small scale production. There are three major process stages in this integrated process.

It corresponds to T300 equivalent not T800..... Intermediate grade sit between T300 & T700 and nowhere close to T800.

Sandeep Unnithan reports that a pop-up test (just for the gas-ejection mechanism) of the K-5 SLBM was conducted in March this year. Says first proper test launch of K-5 could happen any time now.

Looks like our keyboard brigade just ignored this. My man Unnithan just simply laid out all the specs of K-5 SLBM and I havent even seen an article yet??? No change on wiki page as well?? I expect an IRDW article by tomorrow!:LOL:

Specsheet - K5 SLBM:
>naval variant of A5
>Length: 12m
>Diameter: 2.4m
>Weight: >20 t
>warhead : 2 t
>MIRV: Atleast 3
>Will equip S5 SSBNs (by early 2030s)
>gas ejector system test done
>a new underwater launcher(SLBM test barge) for SLBM also tested
>INS Aridaman was comm a few days after this test

Look I respect Sandeep and he is more reliable than most other Indian Defence Journalists but this time he is completely wrong.
Most of those numbers don't make any sense

We know for a fact that K4 is 1.4m in diameter and has a length of 12-13 m
Total Volume of K4 18.5 ~ 20.1 m³

We also know for a fact that K5 will have a diameter of 2.4 m (from the DRDO November 2025 newsletter)
Even if were to assume the length is still 12-13 m (which is still up for debate given we have seen hump back S5 SSBN designs)
The Total Volume of K5 would be 54.3 ~ 58.8 m³

That's nearly 3x increase in volume

Even if we assume K5 will carry more payload (say 3000 kg vs 1000-1500 kg of K4) it would still have more than double the range of K4,
The closest counterpart to K5 that I can think of is French M51 and that has a 10000 km range (as speculated by think tanks)

In my opinion anything less than 8000 km is very unlikely

K5 cannister for reference

A lot of other stuff you can recognise on the table. Like C2 or C3 section top part of Dhvani glider/ HSTDV . Do you remember that drawing first time i showed ?

I dont understand why people are so sure that is the final design for S5 class SSBN. It was just one of the numerous scaled models that were under study. Why would anyone spend billions to make such an inefficient (& ugly as well) design???

You do you man, I think they do.

If you think he is understating the range, then

whats the problem anyways??? :LOL:

P.S. i really dont understand your volume calculations. Simple cylindrical volume formula of π r² h gives K4's volume as <63 m3 and K5's volume as <217 m3. Sure, the diff is still 3.4 times.

That's the whole point I am trying to make, we don't know how S5 is going to look,
How can your be sure it's not going be a hump back, it's your word against mine. As such the length of the missile is still up for debate
As for being ugly maybe ask the Chinese why they seem to love this ugly design.


Infact If you would look at the attached image of the K5 canister in my previous post you would realise that the cannister is most definitely longer than 12-14 m

You do realise that 1.4 m and 2.4 m are the diameter and not the radius of the missile (cylinder) right, Righttt

Understating the range is a policy design excercised by the govt and as such journalists are not bound by it, if he can freely say Agni V mk2 has a 8000 km range but is "understating" the range of K5 then he truly believes in that number, which is not an "absolute win" it's just him being wrong

Cause thats not a logical thing to do. Each sub will cost 20,000 crores. Why would anyone spend so much money to design a compromised sub??? Hump back design is a compromise that countries made in old times. It induces a lot of drag. It was done cause their missiles were not compact enough.

Its all just guess work. One guy below your post was suggesting 11m to 13m. When this missile conducts its tests and becomes mainstream, we'll know anyways.

Oh shit, my bad :LOL:
divide by 4, k4= <15 m3; K5= <54 m3

Not naval varients of A5.
He said naval equivalent in terms on range.
K5 will be a new missile, a shorter and wider missile than A5.

Substantial weight reduction compared to the 50t A5, if these specs are correct.

It'd be interesting to see how K5 compares to the A5 mk2 which reportedly already uses CRMC for all 3 stages.
 
A5 reportedly weighs somewhere around 40 tons. K5 intends to bring that down further by more energetic and efficient fuel. Just how much fuel efficiency matters is evident in Agni-2 to Agni-P.
Agni-P reportedly uses a new type of fuel.
