    what is the good news that we should be expecting ?

    test firing from undersea by Arihant.

    INS Arihant, India's N-powered submarine, to be operational soon

    In a big step towards securing India's nuclear deterrence capabilities, the reactor on board the indigenously built nuclear-powered submarine INS Arihant is set to become operational within three weeks
    . The submarine, which is over 100 metres long, has been undergoing trials in Visakhapatnam for the last three years .

    Dr VK Saraswat, the chief of the Defence Research and Development Organisation or DRDO, shared these exclusive details with NDTV. He said that once the Indian-made enriched uranium nuclear reactor - which has been in development for two decades - becomes operational, INS Arihant will be ready for sea-trials and will subsequently be commissioned.

    The induction of INS Arihant into the Indian Navy's fleet will complete the crucial link in India's nuclear triad - the ability to fire nuclear weapons from land, air and sea. So far, the US, Russia, France, China, and the UK have the capability to launch a submarine-based ballistic missile.

    Though this comes as good news for India's defence capabilities, there is some concern over the overall strength of India's submarine fleet. India has 14 conventional submarines that run on either battery or diesel and are aging and outdated. Each of them will have completed the standard life-span of 25 years by 2017.

    So hope there will be no more delays for the second one, as the main issue(reactor) is fixed now.

    Range of K-15/BO-5 missile

    The official reported range of K-15/BO-5 missile is 700km.

    The range seem too little to be effective as a sea-based credible deterrent.

    But what is not reported in the media that the range increases with decrease in payload.

    the K-15/BO-5 missile is a the naval variant of the Shaurya missile.
    India To Begin Production of Nuke Missile | Defense News | defensenews.com

    So the range of K-15/BO-5 missile is significantly greater than what's reported in our desi media.
    At 1900km as the range of the SLBM, Arihant should able to deliver the strike package at safe distance away from enemies.
    The only hurdle remains is the induction of Arihant. So in 2014 India is going to have all the 3 legs of its nuclear triad operational.

    According to me, we can expect Indian Navy to have about
    6 AIP (Air Independent Propulsion) submarines
    14 Diesel/Battery powered subs
    and about 6 Nuclear subs by 2030

    no. of AIP subs should be better than 6, most probably 7-8.
    of course all the AIP subs r essentially diesel electric subs with a higher endurance submerged due to AIP.

    Will Arihant have AIP??

    And why do people say that nuclear submarines are more expensive to maintain?? The way I see it, they're less expensive coz of less expensive fuel. And also doesn't need to dock often due to high endurance due to long lasting fuel energy.

    yes thats true

    but i am not sure if the numbers will be more than 6
    i would rather have 20 AIPs

    than 14 diesels and 6 AIPs

    Yaar why shud a nuke sub require AIP?

    AIP mean Air Independent Propulsion

    Arihant used Nuclear Power for Propulsion

    Nukes are more expensive to maintain cause of the Intensive care needed for safety
    and maintenance of the reactor and unlike nuclear power plants
    there is no recovery of cost only expense

    Hence, Nukes are expensive

    But still they have an considerable edge over AIPs
    hence, Nukes are better and most suited for Blue Water Navies

    the need of AIP is to increase the endurance of the subs in submerged state.
    in the simplest sense,
    a diesel-electric system produces a certain amt. of power.
    to run a diesel-electric propulsion system(generate power) u need to burn diesel which requires an air(oxygen)-fuel mixture.
    so diesel-electric subs have to surface to collect oxygen from the atmosphere, which puts them in greater risk of being detected.
    an AIP system as the name suggest is independent of atmosphere,also produces certain amt. of power which is used for prolonged operation period below the sea water. so it increases endurance of the subs for undetected submerged operation. it can be considered as an auxiliary power system for the diesel-electric subs.

    a nuclear propulsion on the other hand generates much greater amt. of power than the normal diesel-electric AIP subs, so its endurance(submerged) is also much higher than those. So Arihant doesn't need an AIP system.

    You can't say "unlike nuclear power plants, there is no recovery of cost, only expense", coz it goes for the alternative diesel powered subs too. Can't be recovered like in diesel power plants.

    So maintenance is expensive. Okey. But doesn't the lower expensive fuel make up for the maintenance cost, v/s how the less expensive maintenance cost for diesel powered ones compensate the expensive amount of diesel fuel needed, and that too very often??

    How do they maintain oxygen levels for the sailers?? Is it separated and collected from the ocean?? Or have to surface??

    Nuclear reactor in the subs, accounts for half of its cost
    that's approx 1.2 Billion USD, a diesel subs wont burn fuel of that much cost in its entire life time.
