INS Chakra/Akula II

Russia will transfer the Akula-II class 'Nerpa' nuclear attack submarine to India on a 10-year lease by the end of 2011, Russian Naval Chief Vladimir Vysotsky has said.

"There are no obstacles for the transfer of the submarine to the Indian Navy by the end of this year," Admiral Vysotsky was quoted as saying by Interfax. He said the Indian crew had undergone the full course of training and the submarine was being prepared for delivery trials.

Under the lease contract, estimated to be between $650 million and $900 million, India had funded the completion of the Nerpa nuclear submarine at Amur Shipyard before the Soviet collapse.

The Nerpa was to be inducted into the Indian Navy like INS Chakra by mid-2008 but on November 8, 2008, shortly after the sea trials commenced, as many as 20 sailors and technical workers were killed onboard, while they were asleep, due to the release of toxic Freon gas following a technical problem in the automatic fire suppression system.​

It's very old news (more than 1 year). All latest news related with Nerpa already posted. I don't see anything new in the above news.

What route is it taking? Around the world and being tugged by a fishing trawler? If it set sail in Aug 2010, then how come it is not in India by now? And why would it take a year and a half to arrive?

The article doesn't talk highly of the Nerpa. It even says that it's made out of steel from China and hence had leaking problems.

An unnamed worker at the Amur shipyard told Komsomolskaya Pravda that there were "questions about the quality of the metal that was used in building the nuclear submarine", some of which had been bought from China, and alleged that "when the first trials of the submarine were carried out water was leaking in between the seams! So it is not surprising that the work dragged on."

I don't think it is a problem with the steel, but the welding of two steel pieces. That is what it sounds like when I read this:

INS Chakra Akula II nuclear sub?


The following GOI Press release is interesting, because, l believe, no IN sub in service can launch missiles.

Objection to Test Firing of Missiles from A&N Islands

Indian Navy proposal for temporary use of Tillanchang Island for missile firings from submarines was discussed at the 23rd Meeting of Standing Committee of National Board of Wildlife (NBWL) on 14th October 2011. The expert panel noted that the test firing was likely to have an impact on the lifecycle of the Nicobar Megapode. A joint inspection by the expert and Chief Wildlife Warden, A & N Islands has been ordered by the Standing Committee of National Board of Wildlife.

This information was given by Defence Minister Shri AK Antony in a written reply to Shri A. Elavarasan in Rajya Sabha today.

• Nuclear propulsion? Yes.
• Nuclear missiles? No.
• So, is INS Chakra a nuclear sub? Yes and No.

To be fair, I believe leaking more likely would be due to bad welds, not where the steel came from.

[And pmaitra already said that. D'oh!]

I think, Since Missile is not yet tested, So It's won't have nuke missile in starting.

Once Objection to Test Firing of Missiles from A&N Islands will be cleared, Testing will be done. Then it will be equipped with nuke missile.

In Short, It is capable but after testing only it will be operational I suppose.

1. We are not getting this: The Project 941 or Akula, Russian "Акула" ("Shark") class submarine (NATO reporting name: Typhoon)
2. We are getting this: The K-152 Nerpa (Russian: К-152 «Нерпа») is a 8,140-tonne (8,010-long-ton) Project 971 Shchuka-B (NATO: Akula II)

The submarine we are getting is not the nuclear ballistic missile capable Akula but the Nuclear Powered Attack Submarine Shchuka-B. So no, we will not be testing any nuclear capable ballistic missiles from INS Chakra.

It's Nuclear capable Cruise Missile and not Ballistic Missile.

Russian Navy's Akula-II could be equipped with 28 nuclear-capable cruise missiles with a striking range of 3,000 km (1,620 nmi; 1,864 mi), the Indian version was reportedly expected to be armed with the 300 km (162 nmi; 186 mi)-range 3M-54 Klub nuclear-capable missiles..Missiles with ranges greater than 300 km (162 nmi; 186 mi) cannot be exported due to arms control restrictions, since Russia is a signatory to the MTCR treaty.

WWII submarine forces had the primary mission of sinking enemy shipping, and the measure of success was always tonnage sunk. In current doctrine for submarines (of any country) the mission seems to have changed to launching missiles to attack land targets or large naval targets such as aircraft carriers. Is sinking of enemy shipping not important now because nobody thinks a war will last long enough for that mission to have much importance?
