    He said it might externally resemble the Alfa/Lira. i.e. the hull could LOOK similar.

    The internal technology would anyway be some 2 generations ahead - I have no reason to believe the Lira's mission will be carried over, but some design knowledge could.

    the source is hypothetical :laugh:

    and lets leave at that.

    as for surveillance and intelligence capabilities ask the Mongolians :azn:

    Indian companies r doing serious business and are much in demand for their products and services in the surveillance and intelligence field. they r prolific in middle east , Latin America , SE Asia , sometimes the Americans too shows interest .

    due to the nature of the business, almost nothing is known about them

    they also offer non invasive submarine cable tapping capabilities and services, AFAIK not in the deep seas but somewhere close . :azn:

    i can name 2 companies

    one starts with S

    another starts with C

    it is funny Indian agencies cannot utilize them becz of stupid Indian laws but nevertheless the agencies do utilize their services in a long tedious roundabout way via shell/fronts both in and outside India.

    As you wish.

    Considering information on Husky has only been around since about 2015, "ages ago" seems a tad hyperbolic, no?

    Such information exist already inside defence circle since 2014, and even an article exist on it.

    In today's information world that is indeed ages ago.

    BTW, Indian SSN is not a Husky. Even no submarine class of Russian Navy ever enter into Indian navy's servive. IN's SSN indeed resemble like a Russian. But nothing more than that.

    IN made huge structural, electronics, sonar, weapons and even reactor changes. That reactor was tested by DAE. That submarine is totally a property of IN and no one else.

    Obviously, whole industrial and design help came from Russia, including for PWR reactor.

    The Alfa is a very small sub for an SSN, Gessler. Though, have already shared what little I know. So will desist from further debate. Subject matter experts could comment.

    @kaku are they working as consultants or are they helping with the actual design?

    The whole design came from Russia, and Russia took a huge amount of money for transfer of IPR. From huge I mean really huge., billions of dollars. IN made several changes in design, including structural.

    The whole funding of program came from PMO, and not from MoD. So, out of purview for any audit. We only able to see this sub from google earth. And nowhere else.

    Because SBC is not an actual builder.

    Many of you have quoted me here for comments and I have refrained from it. There is a reason for it. IN has designed a sub of its own. They are not looking for design but for tech to make it the best.

    We dont know efficiency of reactor, or even the reactor is HEU which using above 90% enriched uranium and required refueling or not for lifetime. But I am guessing the reactor is HEU PWR.

    But the story of 45 MW is only possible in 3 cases:-

    1) Indian SSN is like Rubis class, and not weigh beyond 2000 ton.aro
    2) 45 MW is actually 45 MWe, and actually rated reactor is ( considering 35% efficiency) around 130 MW.
    3) A 5000 tonne sub equipped with 45 MW-thermal never able to go beyond 24 knots, if that is okey for IN. Then I think story is true.

    India gets moving on $ 2.5 billion refit, lease of third Russian nuclear submarine

    India is moving ahead with its plan to lease a third nuclear attack submarine from old ally Russia for an estimated $ 2.5 billion. This will include the refit of the boat at a Cold War-era shipyard followed by a ten-year deployment with the Navy.

    The lease plans and discussions are being kept under wraps by both sides but ThePrint has learnt that work is on at a fast pace since the agreement was signed in October last year.

    Tentatively being called the ‘Chakra III’ – India has leased two nuclear-propelled submarines from Russia in the past, including one currently in service – the project is likely to take over six years to be completed at a Russian shipyard.

    Sources have told ThePrint that an Indian team that visited Russia has inspected and identified the hull of a Project 971 submarine that will be modernised and undergo a thorough refit to convert it into a modern nuclear attack boat.

    Negotiations are currently on to embed a team of Indian shipbuilders to go through the refit process – which will basically build up the entire submarine again from an empty hull – to give them hands-on experience with complex submarine technology.

    The refit will be carried out at the Russian shipyard town of Severodvinsk, where Indian aircraft carrier INS Vikramaditya was also constructed. According to officials involved in the project, it would take 78 months for the project to be completed.

    The one factor the Indian side needs to work on is that the government needs to pay for both the refit and lease of the submarine – something that will require a deviation from set financial rules.

    The decision to go in for a deep refit of an existing submarine was taken because building a new one could have cost twice as much. The Project 971 submarine will be taken off from the Russian Navy for the lease.

    There has been no announcement yet on which particular submarine would be refitted, but reports have named the Kashalot (K 322).

    However, sources have told ThePrint that the two Project 971 submarines that are presently docked at Zvyozdochka shipyard in Severodvinsk are the Samara (K 295) and Bratsk (K 391), both of which were transported there in 2014. Indian teams are believed to have inspected both hulls.

    The refit and lease of the Chakra III is particularly important for India that has cleared a project to construct a new line of nuclear-powered, but conventionally armed submarines (SSNs). The mammoth plan, expected to cost over $12 billion, is for six modern vessels to be made in India – which will require trained shipbuilders and design help.

    The first official comments on the plan came in 2015, with a senior Navy officer revealing that the design work had started on the project, and the aim was to come out with a new class of submarines within 15 years.

    So again to reiterate

    1) We are looking to lease 2 more hull to have a total of 3 akula class Subs?
    2) So we have the Ex nerpa (K152) , as per reports possible Ex samara (K295) and Ex Bratsk(K391) ..... what about Ibiris??

    No, K152 will return to russia after lease. New Akula will be replacement for it.

    One of Kashalot ,Samara,Bratsk will be selected for refit and new lease.

    He counts first chakra (K-43) when he says third.
