Arihant-class SSBN - News & Discussions

Arighat is rumored to be around 25% longer than Arihant with a 120 MW reactor. Both the reactors are copies of Russian reactors. In fact, they are heavily built on Russian components if not sourced entirely from Russia (from a third-person account).
Wasn't there another one ? Aridhaman or something ? What happened to that one ?

The talk is Arighat was on active patrols by the time Modi announced the third triad. And Aridhaman is on sea trials. still rumors. No one is even confirming this yet.

But we know for sure Aridhaman is in the water. Because the shell construction for the next 2 has begun and SSB can manufacture only 2 at a time (from the size of the shed fro google earth).

And if we have an active underwater deterrent one sub should always be out at sea. You will notice one sub always parked at the piers in Vishakapatnam (and in few pictures it looks longer that usual.)

In the pics that I took sometime back the sheds were pulled back a lot more than before, revealing the size of the sub. I can see at least one silo open. I posted the pics here, post #30 :

INS Arighat has completed sea trials and will be officially commissioned next year.
INS Arighat is 12-13k tons in displacement. Carries 8 nos. K-4 missiles.
All of the subs will be in service by 2023. L&T made the hull/shell of the Arihant class.

Weight information needs clarification, is 12k tons referring to surfaced weight or submerged weight, if it's submerged weight, surface weight will come somewhere between 8-10k tons. If it's surfaced weight, submerged weight will be well close to 14-15k tons.
But Arighat is said to be a 4-silo based SSBN similar to Arihant with similar tonnage.
We will never know what exactly goes on woth our secretive nuclear sub project.

Will the Arighat be armed with K-4 missiles or K-15??
It can carry both, which will it carry, only few people will know about that.

No such clarification was given. At the moment we are wondering where the Aridhaman went all of a sudden.
 
Aridhaman was actually Arighat
INS Aridhaman was the name used for a long time to denote the second SSBN. The Navy had all the time in the world to correct the name if they wanted to. In fact the Aridhaman name came from unnamed sources with in the Navy. Then comes the day of reckoning, the Navy drops the old name out of nowhere and the name Arighat comes out.

It is possible that the Navy was just sloppy with media management and never cared about what the public called the second SSBN. So they never corrected the media reporting on it. When the launching ceremony came they named it and moved on. So what was known as Aridhaman was officially named Arighat.

It is also possible that those two are different subs. The Navy just doesn't want to talk about the INS Aridhaman in public. The name Arihant also came in public knowledge by some unnamed Navy personnel mentioning the name long back, why would the Navy change the name for the second sub all of a sudden.

These are just conjectures, of course.
 
Some say Arighat has 4 VLS, while some say 8. It's unclear yet. From what I understand, they are using the same reactor as the one on Arihant, so there will be limits to how much power you can pull out of it if we are to enlarge the submarine for the extra VLS. It's possible that people have somehow started confusing the Arighat with S4. What I've discerned is Arihant and Arighat are sister ships.

It's possible Aridhaman is the S4. Just guessing. But these are most definitely bigger than Arihant.

S5, S6 and S7 should comfortably cross 12000DWT, I doubt S4 and S4* will even cross 8000DWT.

The news about Arihant completing a month long deterrence patrol... This means the nuclear warheads mated to K-15 missiles... Has India managed to build the necessary command and control structures... ? or is it that the missiles are armed with conventional warheads..
 
Any idea as to how the Arihant class subs look from the inside.
Does it look like the Soviet era Akula class, Delta class subs or more modern subs like the Borei class, Virginia class, Astute class subs??

What do you understand from "deterrent patrol" by a strategic platform?

Oh please.. genius.. India has been keeping its missiles de-mated from warheads.. There was not much info about the Nov. 2018 patrol. Also, is there any information that India has mastered ELF communications, and built the necessary safeguards and redundancies.. If the missiles were mated with nuclear warheads, then, it is certainly cause for celebration...

You are wrong and ELF has been functional for over two decades

I've read reports that the K4 hasn't yet been fired from the Arihant but all such tests till date have been thru under water pontoons. In that case the only deterrent we have is the K-15. Which isn't much to begin with. It barely threatens Pakistan while China remains out of reach.
