    India's first nuclear submarine set for trials


    August 7, 2012


    India on Tuesday said its first home-built nuclear submarine was set for sea trials, as it detailed billion-dollar projects to arm its navy with warships, aircraft and modern weaponry.

    The indigenous 6,000-ton INS Arihant (Destroyer of Enemies) was unveiled in 2009 as part of a project to construct five such vessels which would be armed with nuclear-tipped missiles and torpedoes.

    "Arihant is steadily progressing towards operationalisation, and we hope to commence sea trials in the coming months," Indian navy chief Admiral Nirmal Verma told reporters.

    "Our maritime and nuclear doctrine will then be aligned to ensure that our nuclear insurance comes from the sea," Verma said,

    Arihant is powered by an 85-megawatt nuclear reactor and can reach 44 kilometres an hour (24 knots), according to defence officials. It will carry a 95-member crew.

    The Indian navy inducted a Russian-leased nuclear submarine into service in April this year, joining China, France, the United States, Britain and Russia in the elite club of countries with nuclear-powered vessels.

    Verma said 43 warships were currently under construction at local shipyards while the first of six Franco-Spanish Scorpene submarines under contract would join the Indian navy in 2015 and the sixth by 2018.

    The admiral said the navy was also poised to induct eight Boeing long-range maritime reconnaissance P-8I aircraft next year.

    Why INS Arihant, submarine in final stages of testing, is so important

    New Delhi: The INS Arihant, India's indigenously-built nuclear-powered submarine which is capable of carrying nuclear missiles "will be going for sea-trials soon," Chief of Naval Staff, Admiral Nirmal Verma told reporters today in New Delhi.

    The submarine is now the in last stage of testing. Sources have told NDTV that barring any major set-backs, the INS Arihant should be able join the Indian Navy within the "next 18 months".

    The advent of INS Arihant into the fleet will complete the crucial link in India's nuclear triad - the ability to fire nuclear weapons from land, air and sea. Admiral Verma, however, refused to give details of the weapons package on board the nuclear submarine. "I will not want to get into the details" he said.

    The sea-trial of the INS Arihant was scheduled to start last year but was delayed because of technical glitches.

    The Defence Research and Development Organization (DRDO) announced last month that it has successfully developed nuclear-tipped submarine-launched ballistic missiles (SLBMs). Long shrouded in secrecy, unlike surface-to-surface nuclear missiles like Agni, the SLBM was a closely -guarded secret while in development and was called the 'Sagarika Project'. In all probability, the INS Arihant will take this missile on board. So far, countries like the US, Russia, France, China and the UK have the capability to launch a submarine-based ballistic missile.

    Although INS Arihant signifies a huge jump for the Indian Navy, the good news ends here. India's fleet of conventional submarines is fast depleting. 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.

    Admiral Verma admitted concern over the fact that upgraded versions have been grounded by bureaucratic delays.

    At any given time, only seven submarines are available for deployment and are split on either coast. Seven submarines are mostly unavailable because they need to be serviced, refitted at increasingly short terms. Also, because the boats are aging fast, their lifespan need to be extended and therefore they are not deployed.

    The Indian Navy's 30-year submarine programme, devised in 1988, envisaged buying six submarines from the West and countries in the East like Russia. India was to use the acquisition process to gain enough knowledge to build the next 12 submarines on its own. But Indian shipyards have largely been unable to either pick up the requisite technology or capability. Shipyards like the Hindustan Shipyard Limited which was originally supposed to build at least 3 submarines have been found to be incapable of building submarines.

    The Indian Navy has now approached the government to be allowed to build two submarines in the shipyard of the foreign collaborator. "It is not exactly asking for importing two submarines. We are asking the government to allow us to build two submarines in their shipyard. In the long run it will be help our technicians gain expertise" and cut down in delays when building in India, Admiral Verma said.

    UK does have the capability of launching SLBM, but they neither have the technology (working) to build one nor the launch codes. The lone British SLBM is Trident, which is an American SL ICBM, shared coz' of their mutual defense agreement.

    Re: India's first nuclear submarine set for trials

    I am eager to see the first glimpse of whole submarine.
    Will have to wait for few days only.
    I think we will see the launch of "K-15 Sagarika missile" during testing.:tup:

    India’s SSBN Shows Itself


    [​IMG]
    A new satellite image appears to show part of India’s new SSBN partly concealed at the Visakhapatnam naval base on the Indian east coast (17°42’38.06″N, 83°16’4.90″E).


    By Hans M. Kristensen

    Could it be? It is not entirely clear, but a new satellite image might be showing part of India’s first nuclear-powered ballistic missile submarine, the Arihant.

    The image, taken by GeoEye’s satellite on March 18, 2012, and made available on Google Earth, shows what appears to be the conning tower (or sail) of a submarine in a gap of covers intended to conceal it deep inside the Visakhapatnam (Vizag) Naval Base on the Indian east coast.

    The image appears to show a gangway leading from the pier with service buildings and a large crane to the submarine hull just behind the conning tower. The outlines of what appear to be two horizontal diving planes extending from either side of the conning tower can also be seen on the grainy image.

    The Arihant was launched in 2009 from the shipyard on the other side of the harbor and moved under an initial cover. An image released by the Indian government in 2010 appears to show the submarine inside the initial cover.


    [​IMG]
    The Indian government published this image in 2010, apparently showing the Arihant inside the initial concealment building.


    The new cover, made up of what appears to be 13-meter floating modules that can be assembled to fit the length of the submarine, similarly to what Russia is using at its submarine shipyard in Severodvinsk, first appeared in 2010. Images from 2011 show the modules in various configurations but without the submarine inside.

    The movement of the Arihant from the initial cover building to the module covers next to the service facilities and large crane indicates that the submarine has entered a new phase of fitting out. The initial cover building appeared empty in April 2012 when the Indian Navy show-cased its new Russia-supplied Akula-class nuclear-powered attack submarine: the Chakra.

    It is thought that the Arihant is equipped with less than a dozen launch tubes behind the conning tower for short/medium-range nuclear-armed ballistic missiles. Before it can become fully operational, however, the Arihant will have to undergo extensive refitting and sea-trials that may last through 2013. It is expected that India might be building several SSBNs.

    Like the other nuclear weapon states, India continues to modernize its nuclear forces, despite pledges to work for a world free of nuclear weapons.

    INS Arihant Sea Trials By Month-end, Induction End-2013

    India is readying its home-built INS Arihant nuclear-powered submarine for sea trials by this month end and its possible induction by end of 2013.

    INS Arihant will help India to complete its nuclear weapons triad – the capability to fire nuke-tipped missiles from land, air and sea – a key deterrent and a major boost to its proclaimed second-strike capability, as stated in its nuclear weapons doctrine.

    The 6,000-tonne submarine is at present under harbour-acceptance trials at the naval docks at Visakhapatnam.

    India had unveiled INS Arihant in July 2009 and it has been built with major help from Russia, particularly its miniaturised nuclear reactors.

    Nuclear submarines are considered a strategic asset in view of its capability to lurk deep in the sea closer to enemy waters for months together and strike at will at land- and sea-based targets. Add to this long endurance, the stealth and surprise that come with the ability to launch submarine-launched nukes.

    Unlike conventional diesel-electric submarines that can stay underwater only for three or four days at a time and have to surface, nuclear-powered submarines can stay under water for three months without the need to surface, primarily due to the clean source of energy that helps propel it.

    China already operates 60 conventional submarines and 10 nuclear submarines in its fleet. Indian Navy also operates 12 diesel-electric submarines.

    When Arihant joins the Indian Navy fleet, it will be the second nuclear-powered submarine that India will be operating, alongside the INS Chakra, a Russian-built Akula-II K-152 Nerpa submarine inducted on a 10-year lease early this year.

    While Arihant will be armed with nukes, Chakra cannot be so armed due to non-proliferation commitments of Russia. India has signed agreements with Russia to help maintain those non-proliferation commitments of Russia.

    India is already in the process of developing submarine-launched nuclear arsenal non-proliferation regimes, under its lease agreement with Russia.

    "We expect to have good news for the nation very soon," Indian Navy chief Admiral DK Joshi said Monday, ahead of Navy Day Tuesday, when asked about Arihant becoming operational.

    Joshi went on to elaborate that the sea trials would happen "very soon” and it could take "about a year” to complete.

    Arihant was to be inducted into the navy after all the trials by end of 2012. However, the sea-acceptance trials in February this year could not take place for unspecified reasons.

    When ready for deployment, Arihant will be used by India to test the 750-km-range K-15 submarine-launched nuke-tipped missiles and the under-development 3,500-km K-4 submarine-launched ballistic missiles.

    Submarine-launched nuclear ballistic missiles are the most critical leg in the nuclear weapons triad, as India already possesses nuclear ballistic missiles that can be fired from the land and from surface warships, apart from being air-launched from combat planes.

    Arihant and its future follow-on vessels would be armed with the K-15 and K-4. These vessels will have four silos to carry 12 K-15s and four K-4s.

    After Arihant, India plans to have two more of the same class of nuclear-powered submarines in its fleet.

    Joshi said the navy will compare Arihant with Chakra, and subsequently incorporate these experiences in the two follow-on nuclear-powered submarines. The next submarine in this class may be named INS Aridhaman, which also means 'slayer of enemies' just like Arihant.

    Re: India's first nuclear submarine set for trials

    Two more hulls are nearly ready. If all goes well for Arihant than you can expect to have second by end of 2013 to be commissioned by end 2014 and third commissioned by end of 2015.
    We might possibly have another two taking the fleet to 5 nuke subs + Akula by 2018 and at the same time we will have six scorpene also joining the fleet. so we will have a sub fleet of 26 by end 2018 of which six will be nukes.

    The design for follow up bigger nuke subs is ready but I am not aware whether go ahead has been given for them. It all depends on govt.

    These three are sister ships, identical in all respects except that may be some internal equipment might be different.
