    take someone else's help its not necessary o involve russia, all weapon systems of air force and army and navy too to some extent are running behind schedule and facing massive delays affecting there war preparedness. DRDO/HAL needs overhaul at massive scale in shape of new induction of fresh man power with enhanced salaries and the competition from private sector

    Which again shows the problem in the new SP policy. If L&T goes for this joint development, but won't be chosen as the Indian SP, the know how is wasted. Even if they get SP, they also need the Russian subs to be shortlisted, otherwise the technology can't be offered to IN again.

    Sterling AIP is used by Japanese in there soryu class submarines. They are better than MESMA of French. Soryu is better compared to Amur. stirling-aip-740x416.png AIP_MESMA.jpg

    SP does not stop you from making parts. SP is an integrator not full system producer.

    We will not import AIP.

    Project 75I tender requirement includes AIP . Unless there is provision for installing Indian AIP the imported one will go through.

    That needs to be seen, the whole point is, to give the SP that much work, to make it worth the investments in infrastructure and technology. Why would the SP then divert production to other players?
    And as I said, even if L&T will be selected, they won't be able to integrate Russian techs into a French or German sub.

    AIP technology can be installed on existing older generation submarines by inserting a new hull section during a retrofit. Integrating one technology to another old submarine is not a problem. A Siemens PEM fuel cell is compact to be fitted with out much modifications. AIP_PEM.jpg

    That is always the case ! It depends on the selection.
    No single entity can produce entire system.

    Not necessarily, if you have NATO compatible techs and weapons, you can add them to subs of different OEMs. Russian technology however is limited in use and neither will Russian subs give us the possibility to add European techs or weapons.
    Of course not, sub systems like the engine will be produced from other companies and then integrated into the main production line, but no major production part is likely to be diverted and most likely only if the SP agrees.
    Take the Avro replacement as an example, where not a single privat Indian company other than Tata showed interest in the license production, because the investments they would have to make, would not be covered by a small order.
    The SP policy is trying to solve exactly this problem, by reducing competition of PSUs and increasing the possible production for privat players, to make Indian defence more attractive.

    I always believed that work ethics of an employee can turn the tables, i guess the tables are still where they are and DRDO has no work ethics, i say they are biscut party....

    DRDO's lab NMRL is developing two different types of fuel cells for AIP operation. PAFC & PEMC. Phosphoric Acid Fuel Cell is for integrating into submarines. DRDO fuel cell photo. 3754-05fa85f2b7176360cb7dce6c8eee1f1a.png 3755-6a32259e5f803d213bf8f0a4a7e91757.png

    As far as i know, even kalyani is playing with old stuff that the previous company he bought made and he has only reverse engineered, the only place where we excel is ship hulls.

    They don't need to reverse engineer, since they own the know how now and can apply it directly in India. Privat players buying foreign companies and their know how is the best and fastest way to close the knowledge gap, but it requires access and funds of course. China is buying foreign companies to get the know how on a large scale, Indian companies did that to an extend till some years ago (Tata buying Jaguar and Landrover for example) and Kalyani gave us an important know how push in the howitzer field, which will be promising for the future.

    AIP technology is a must for future submarines. After making a prototype it is shameful to go for outside help. A phosphoric acid fuel cell technology based ruggedized N 11 stack of 11.5 kW capacity developed by DRDO. nmrl-product-2.jpg
