We will likely never see the interior of a Arihant boat. And that is the way it should be. Rest assured on that.

Thank you to one and all who solved the mystery.

^^ it was in the Indian Navy Facebook page... the picture of the men sitting on the diving pane and conning tower came as a surprise... what attracted my attention was the greeninsh tinged floor... which was odd considering I would expect the surface to be smooth and dark... that was probably a mat placed on the surface to obstruct the missile hatches from being seen (or stepped upon). Anyway. Thanks to all gurus, we have an upclose and personal Tasveer of S2

Saar, that greenish tinged floor (picture below) is nothing more than algae. You can see that in the next picture as well (also below) all along the waterline. And that vessel you see is NOT S2, rather it is INS Sindhukirti --> a Kilo Class submarine.

First Deterrent patrol Marks Major Step for Indian Submarine Force




Frm here...

The Indian Navy’s new ballistic missile submarine (SSBN) INS Arihant was the boomer that completed the month-long deterrent patrol. Whilst this is not insignificant – it is the first country outside of the five members of the U.N. Security Council to develop this capability – it also shows how far away India is to achieve its goal of joining the other great powers in establishing a credible sea-based deterrent.

Only the U.S., U.K., France and Russia can sustain continuous-at-sea deterrent patrols, which a provides continuous launch capability of a submarine-launched ballistic missile (SLBM) by maintaining at least one SSBN on station at any one time that could fire a nuclear missile. A continuous patrol requires a minimum of four SSBNs.

The patrol as a statement will have more effect in diplomatic circles than in military ones. India wants to join the club of countries that can support a sea-based deterrent and eventually achieve a continuous at-sea nuclear deterrent. It also means India will have the ability to launch all three air, land and sea-based types of nuclear weapons and a more robust second strike capability.



A second SSBN to follow Arihant was reported in Indian media to have completed sea trials. Named Arighat, the boat is due to be delivered next year and is expected to be larger than Arihant with a complement of eight K-4 missiles instead of four. Another two boats after Arighat are planned to be commissioned by 2023. Following from these first four Arihant-class boats another batch of even larger SSBNs is expected.

I call BS on this article. will call out a few turds

1.
Modi’s triumphalism belies Arihant’s modest capabilities. The submarine does not add substantially to India’s second-strike capability — at least, not yet. Until and unless India deploys an SSBN fleet carrying missiles with intercontinental range, which could take decades

2.
Arihant’s first deterrent patrol lasted merely 20 days, suggesting endurance issues with its nuclear propulsion package.

3.
It also required a nuclear reactor double the size of previous boats that could endure longer operations at sea.

^^^ ya ya just another think tanker paid lifafa pandu out to show his prescription with zero knowledge of how n-boats work. give him a kick on his rump and let him go.

First they ignore you, then they laugh at you, then they fight you, and then you win.

It's interesting that the ones that laugh loudest is often one's own (or ex-own). I wonder if this phenomenon happens in the Chinese diaspora and their think tank articles.

Poorly written article as author tries to reassure US readers India is not a threat and has robust command and control. While doing this he questions P.M. Modi's deterrent patrol statement.
Those IN officers who talked to him will be regretting their talks.

Can easily be forgotten.
Lots of useless history.

The author was recently awarded PhD from JNU New Delhi and then absorbed into think tank of massaland directly with no real world experience. This literature should be trashed good paper for selling salty nuts

Bugger is only trying to make a mark in the literary and defence expert world.
Let me make an analysis of my own regarding this otherwise berozgaar turd

Given that this article written by him is poorly researched and speculative, and grossly underestimates true capabilities of the Arihant, It is very likely that the author has low two digit IQ.

Some of the bird droppings i listed are just plain technically wrong . Endurance at sea is not a feature of a bigger power plant. Shows he knows nothing basic about submarines

according to this article Ajai Shukla(from behind a paywall) says the installed power power generation for Arihant's reactor is 190MWt. Assuming a 20% efficiency the energy output comes around 38MWe. I really cannot say if it is underpowered or not. seems okay to me since AFAIK a large 65k ton ship require approx 80 MWe with EMALS.

This brings a question to my mind, the above link says it would take 10-15 years to get to a 550-600 MWt reactor for Vishaal. Why cannot we put two smaller reactors of ~250-300 MWt each in Vishaal and operate? Surely we can increase output by that much in 4-5 years. Unkil does that with Nimitz class albeit with an output of ~550 MWt each.
To be clear I have nothing against Diesel Powered IEP. But operating EMALS with it will surely increase cost, time and space usage.

we might want to keep our limited reserves of uranium to power our nuclear subs. I doubt anyone is willing to export uranium for military powerplant uses to India at this stage in the game. russia, niger, brazil may have huge reserves which we should aim to import in bulk and stockpile if we can change the layout internationally.

the uss enterprise had 8 reactors

All the news I read attributed to long development time and no cost sharing agreement. They wanted to build a 500+ MWt reactor. Who knows, maybe the need was for two 500+ MWt reactors in Vishaal.
