    Akula SSN taken on lease are sent to Russia for MRO on a regular basis. The very basic maintenance is done in India.

    Six years for upgrade may therefore mean that currently Russia is not in a position to lease an Akula SSN. And the one that can be spared is probably not sea worthy right now and will take at least 6 years to upgrade.

    Most likely its a case of the available boathouses being fully engaged with new builds and upgrades/repairs.  The existing workload takes priority, and it may take 2-3 years for a slot to become available.

    The identity of the 971 slated as the future "Chakra 3" changes frequently, and currently it seems to be K-391 Bratsk, but given that they are talking about 6 years and a couple of billion USD, perhaps they have decided to complete the Iribis, currently preserved at the Amur yard (unlikely, not sure if Amur retains nuke boat capabilities after all this time)? It seems strange that if her completion isn't feasible, why has it not been broken up?  Completing Iribis would net the Indians a brand new boat, and a good number of technological upgrades one might expect (as they would finish her with modern systems, electronics and weapons rather than the originally intended 1980s vintage outfitting).

    However, at least 5 Akulas are available. Not sure why one of these Akulas can’t be leased to India say within a year’s time. Even as I speak around 6 Akulas are already undergoing modernization in Russia.

    The deal for K-391 Bratsk or perhaps K-295 Samara has already been cleared and it will arrive here in India around 2025.
    I was referring to recent reports about another Akula SSN that India wants to lease apart from the K-391 Bratsk. This is a NEW deal.

    Torpedoes will probably remain the same, but launch tubes meant for firing Kalibr might not be able to fire BRAHMOS.
    I am not sure what are the upgrades being carried out by the Russian Navy on the Akula’s EW & decoy systems, sensors or weapons. Not much open source information is available, just some generic description about the upgrades, for example “new sensors”, “new cruise missiles” etc.

    This is correct, the shipyards are overloaded with work, and new submarines have preference for the Russian Fleet.
    In addition, the Pacific shipyards are no longer capable of building nuclear submarines, only repairs / modernizations.

    I am not sure what happened with Irbis, India ruled out finishing it, opting for.... Bratsk?
    It is possible that the Irbis was scrapped along with the Kashalot, since she was only at 44% or slightly more,

    Now in Bolshoy Kamen the 949AM Irkutsk is modernized and after that, the Cheliabinsk also will be modernized
    Also the ex-Magadan is being repaired. This submarine could later be modernized to 971I, since it is already theoretically out of the fleet.

    In no way, the Akulas of the Northern Fleet are not available for the send to India, they will return to service at the same time that the Victor III and Sierra II finish their period of work.
    The available submarines are the Samara or Bratsk (one of them), the ex-Magadan and the Nerpa
    The Pacific Fleet must retain at least three Akulas in addition to two 949AM

    There are not 6 Akuals in modernization, at the moment there is the Leopard and maybe the Samara started recently
    Bratsk and Volk await their turn after them. The shipyards are very busy building new ships and submarines
    The Tigr (at SRZ Nerpa) and the ex-Magadan (in Zvezfa) are only getting a "MLU" repair
