By this, N korea deserve to be a permanent UN memeber. Its not the missile tests making u a worthy UN permanent member, your capacity to sides with righteousness, your ability to raise your voice, your ability to make stand did have an impact.

It's a noisy sub for sure, don't think it's even close to Akula which has a much bigger powerful reactor.There are only two small clues about it.
As per Trubnikov, an ex-Russian ambassador to India, the Arihant's based on the Akula class and has a similar noise level, possibly referring to the Typhoon class.
And there's this:
Is the noise level comparable to other submarines of this class, since that is one way of detecting submarines?INS Arihant is an Indian design: Anil Kakodkar

Yes, I think so. You have seen the inside. Tell me if you felt some sound there?
Compared to a power reactor the sound was minimal.
Compared to machinery running in any other place, did you hear much sound? I think this is a very quiet system.
I am not talking about VLF , ELF , or Satcom based Com, which have their limitations....post was about something completely different....about how to communicate undersea safely in communication denial environment ( two way or Multiple)We have both VLF and ELF stations.

We have satellite based comm systems too.

Indian fish hook which is indian SOSUS is completely a different thing....something to do with surveillance using Passive Sonars not communication. I am talking about safe undersea high speed communication two or multiple ways which is impossible without compromising sub location.
Probably using underwater acoustic communication which can communicate to distance of several kilometres underwater but again it has limitations of very low data rate....nonetheless great if we are using it thoughFrom what I understand, new SOSUS networks are being upgraded to act as comm nodes as well. There's also a program called DRAPES.
And I believe it was Sutton who wrote in an article that the SOSUS network can connect submarines in its viscinity to bases. So the network has obviously seen massive upgrades. DRAPES removes cables and replaces them with wireless modems.
As for Fish Hook, because of its ability to communicate, the Chinese were complaining to the US and Japan about India using it for area denial. Which is why I believe the reports about the Sumatra-A&N wall being of Indian make is false. We are likely just paying to be part of it. We need our own pan-IOR network.
Most such communication is using Acoustic waves which are inherently slow at data transfer...it's their property, no amount of cutting edge will change limitations imposed by Physics, but they can be used for two way communication, unlike VLF, ELF but rather at short distances.
That's a SLBM. That's what we know. Unlikely that it's K4. Might be K5/K6.
K4 missile has 6000kms range with 4 MIRVs and 2tons payload....
Now that's some serious payload and range. DRDO comes up with surprises every now and then....
It's a K 5...slide is from a DRDO presentation by DR Saraswat at IIT-B back in 2014
