    I'm not including SSNs in this count.

    1 Arihant, 2 Aridhaman, 1 S4*, and 6 S-5 class = 10 SSBNs

    SSNs are separate from this.

    The numbers of SSBNs will be such that we will always have atleast ~50 nukes on station.

    Sandeep Unnithan. Exec Editor, India Today who was first broke stories on development of INS Arihant and development of K-15 and K-4 Submarine Launched Ballistic missile has revealed, more about India’s Nuclear Submarine Plans and has confirmed that INS Aridhaman which will be India’s Second Ballistic Missile Submarine will be stretched Arihant Class ship which has double the Missile carrying capabilities and is unlikely to be called Arihant sister ship rather will be known as Aridhaman lead ship of a new SSBN Class .

    Sister ship of Aridhaman which will be similar to the lead ship Aridhaman currently is designated as S4 and another follow on Sister Class dubbed as S4* (Plus) will make up Three Aridhaman Ballistic Missile Class Submarine fleet of Indian Navy.

    Unnithan also confirms that India Navy already has started working on the successor of Aridhaman Ballistic Missile Class Submarine at least a decade ago and new larger Ballistic Missile Class which will be designated as S5 and will be as big as Ohio class nuclear-powered submarines currently used by the United States Navy.

    It is unclear how many S5 sister class ships will be developed at this point in time but the construction of the new class of SSBN is yet to commence and it is likely will go on the floor for nearly a decade from now. Last year Indian Navy was given go head to start design work on the development of Six new Nuclear attack Class Submarines which will be developed in parallel to the Ballistic Missile Class Submarine Fleet so that work on both the projects will continue independently.

    Unnamed Six Nuclear attack Class Submarines are required to be much stealthier to do sneak attack and surveillance roles and it is reported that construction of Scorpene class Diesel attack submarines in India has helped Naval Design Bureau a lot in obtaining technical know how to better understand and develop stealthier hull.

    December will be good this year. The SSBN will by then be given to the navy, for sea trials by SBC.

    India's 2nd Made-in-India Nuclear Submarine to be launched within a month
    Tuesday, September 12, 2017 By: ET Source Link: CLICK HERE
    [​IMG]

    India's second indigenous nuclear submarine is likely to be launched in less than a month's time, towards the end of September or the beginning of October, government sources said.

    Launching of a boat refers to the process of transferring the vessel to the water from a dry dock. Once launched, the boat will undergo extensive sea trials before it is inducted in the Indian Navy some time in 2019.

    The launch is likely to be done by Defence Minister Nirmala Sitharaman in keeping with the tradition that a boat is launched by a woman. The first indigenous nuclear submarine, INS Arihant, was launched in 2009 by former Prime Minister Manmohan Singh's wife, Gursharan Kaur.

    INS Arihant was quietly inducted in the Indian Navy in August 2016. It was the first nuclear attack submarine built by a country other than one of the five permanent members of the United Nations Security Council.

    Being built under the Advanced Technology Vessel (ATV) project at the Ship Building Centre in Visakhapatnam, the second boat, Aridhaman, will have double the number of missile hatches than its predecessor. It will also be powered by a more powerful reactor than INS Arihant's 83 MW pressurised light-water reactor.

    Aridhaman will have a seven-blade propeller powered by a pressurised water reactor and can achieve speed upto 12-15 knots on surface and 24 knots under water.

    It has eight vertical launch tubes and can carry up to 24 indigenously-developed K-15 (Sagarika) missiles or eight K-4 missiles. The K-15 has a range of 750 km while the K-4 has a range of 3,500 km.

    INS Arihant has four vertical launch tubes and can carry 12 K-15 missiles or four K-4 missiles.

    The K-4 missile was developed as the Agni-III missile could not be deployed on INS Arihant due to space constraints.

    Small Pointers of how MSM is cloaked from the reality of our SSBN Program
    1. INS Arihant began sea trials in 16 Dec 2014 in BoB with 9 months of sea trials and afterwards another < 9 months of weapon testing.
    2. INS Arihant fired K-15 Prototype in full operational configuration from a depth of 25m in November 2015 after conducting multiple dummy tests in Sep-Oct 2015.
    3. INS Arihant did ejection test for K4 Mk1 in Feb 2016 with 4 tubes ejection in a matter of seconds. The dummy included a mix of K4 Mk1 and K15 (3 different mission load configs from the same tube) replicas for a full discharge of its onboard ballistic firepower.
    4. INS Arihant fired K4 in a highly depressed trajectory in full operational configuration from a depth of 30m in March 2016 for approx 750 km.
    5. This was followed by INS Arihant firing a full capacity K4 Mk1 at a range of ~4000 km in A&N region. This was covered up by Multiple Brahmos test in A&N in simultaneous days and Navarea warnings issued for the same to clear out the whole area in the pathway.
    6. INS Arihant started deterrent patrolling from July 2016 onwards.
    7. Aridhaman did the first launch in April, 2016 and even participated in a naval exercise (limited capacity owing to deployment of Arihant in a deterrent patrol mission and since Ardhaman was undergoing sea trials) in the later part of 2016..
    8. Beginning January 2017, INS Aridhaman entered into weapon trials and is expected to complete it by September end 2017
    9. Formally October 2017 should see deployment of INS Aridhaman in deterrence patrol role.
    The Indian SSBN program is managed very well and have seen a huge upswing with the NSA Doval coming onboard. The MSM is completely blacked out and a massive surge in budget has been provided to quicken the pace of the under developed units.

    If the pace continues then we will see the indigenous SSN also at a much faster rate then expected.

    A piece of nasty surprise... Codenamed K6 with MIRV is in final stages along with land version A6. A range of 8000-10000 km is expected (based on twin configurations) but officially it will be claimed much lesser (like always). Its expected to be green lighted for testing within next year (unless geo political considerations change that decision).

    Excellent info!

    • What about K5? Has that been renamed K6 or are they separate?
    • Has the S-4 SSBN begun construction?
    • I need an update from your sources regarding the SSN project (follow this up in SSN thread if you like). Is PKSG right regarding the selection of Russian design?

    Adding on a bit here on Point 4 n 5 to be read in continuation.

    If someone was to google, there was a flurry of testing of Brahmos in the period. On 7th May 15, at Pokaran on 8/9 May 15 off Trak Island in A&N. But also 1 off Balasore on the same day.

    There were 02 x Naval Flotillas out for range clearance during the period.

    One can collate with NavArea warnings for the period.

    Also limited moves by Ardhiman were being undertaken as early as your time frame with definitive moves from Dec 16.

    Addendum ... K6 and Agni 6 ;)

    @PARIKRAMA, @Hellfire, the third boat is now nearly fitted out and may enter harbour trials in 6-7 months. Somehow IN is keeping everyoneguessing by one boat.

    main stream media

    Beyond Arihant 2 more hulls were under process for long so next one should be out as well and @vstol jockey is correct... The third boat should be out in 2018 first half for harbour trials

    @Gessler
    What i can say is the length difference of 8-10-12m approx between missiles and diameter difference accommodating different payloads and different diameter (0.7m -1.3 m - <2m).

    SSN design part - I am yet to receive concrete evidence so cannot comment.. will ask around and check...

    Yes Sir, that is very correct and thanks a ton for that vital piece of information.

    So many tests were done that most folks cant even guess which was the main system under test and what was done to cover it up.
