    What we refer to as "AIP" is the method of generating the electrical power, it doesn't restrict in anyway the battery technology used to store the energy. Choice of battery affects the charger technology, but this is a relatively simple issue, and power generation & storage can be developed and trialed independently.

    The fact that there is any news at all, has nothing for a long time.
    Also apparently in March Deputy Minister of Defense said it wouldn't be launched until 2019...

    Could be, but why would the diesel be off for so long?

    no it isn't.

    I guess you have zero experience with diesel during cold snaps?

    It may be related to the AIP and not the engine. Even old kilos don't smoke, why would this thing smoke ?

    There wasn't a specific date given by the poster @Balancer, he does say North & a 2nd poster said it was July.
    The other pic is St Petersburg Navy Day (I presume) so has apparently transitioned before/since.

    "Admiralty Shipyards" are planning to sign in 2018 a contract for two more submarines "Lada"

    Submarines of Project 677 belong to the fourth generation of diesel-electric submarines
