    India launches nuclear-powered submarine
    RIA Novosti

    26/07/200914:41

    In-Depth Coverage MOSCOW, July 26 (RIA Novosti) - India launched its first nuclear-powered submarine on Sunday for sea trials, national media reported.

    The launch ceremony of the 6,000-ton INS Arihant (Destroyer of Enemies) was attended by Prime Minister Manmohan Singh and his wife Gursharan Kaur, the Times of India said.

    The submarine completes India's nuclear triad, making it the sixth country after the U.S., Russia, China, France and the U.K. to have land, air and sea-based nuclear strike capability.

    The submarine will be armed with torpedoes and missiles, including 12 ballistic missiles, and can also be armed with cruise missiles, the paper said. It is powered by an 85-MW reactor, and can reach a submerged speed of 44 km/h (24 knots). It will carry 95 crewmembers.

    The long-running project to build the submarine, completed with Russian help, is part of a $2.9-billion plan to build five submarines.

    The design was based on a Charlie 1 submarine that India leased from the Soviet Union in the late 1980s. Sea trials and weapons tests will take place in the Bay of Bengal, and the submarine is expected to enter service in two or three years.

    Killer K-4 Undersea Missile test fired From Arihant Submarine





    Not withstanding international pressures India has secretly conducted the maiden test of its nuclear capable undersea ballistic missile, code named K-4, from homegrown submarine INS Arihant at an undisclosed location in the Bay of Bengal.

    A reliable source on Friday told ‘The New Indian Express’ that the test conducted on March 31 nearly 45 nautical miles away from Vishakhapatnam coast in Andhra Pradesh was highly successful. The indigenously developed weapon with a dummy payload was reportedly launched from the submarine in full operational configuration.

    The trial was carried out with the support of the personnel of Strategic Forces Command (SFC) while the DRDO provided all logistics. The missile was fired from 20-meter deep and it pierced into the sky after breaking the water surface. INS Arihant had first successfully fired a prototype of K-15 (B-05) missile in November last year.

    The K-4 missile was fired from onboard silos of the ship submersible ballistic, nuclear (SSBN) submarine demonstrating the capability of the newly built underwater warship to fire long range nuclear capable missiles and the killing efficiency of the most advanced state-of-the-art weapon system.

    “Having an operational range of nearly 3,500 km, the missile was fired towards north for a shorter range. It covered more than 700 km before zeroing on the target with high accuracy reaching close to zero circular error probability (CEP),” informed the source.

    DRDO officials however refused to speak on the mission. While the officials associated with K-4 mission and Arihant project were tight-lipped, Director General of DRDO Selvin Christopher did not respond calls from this paper.

    On March 7, this missile was test fired from a submerged pontoon (replica of a submarine) positioned nearly 30 feet deep sea offshore Vizag coast. Although, the DRDO didn’t officially confirm about the secret mission, it was learnt that the test was a roaring success.

    Even as the DRDO had reportedly conducted the first test of the missile system, which was developed under a secret project, in 2010, it officially admitted to have a missile named K-4 with a video footage of the missile launch in the Aero-India show in January last year.

    Reports indicated the K-4 missile with the features of boost-glide flight profiles is designed to defeat any anti-ballistic missile systems. Equipped with the satellite updates to modify accumulated errors from its inertial navigation system, the weapon system is claimed to be quite dangerous and one of its kind in the world.

    The 111-metre-long INS Arihant has four vertical launch tubes, which are capable of carrying 6 torpedoes of 533 mm and 12 B-05 (K-15) missiles or 4 K-4 missiles.

    Powered by an 85 MW capacity nuclear reactor with enriched uranium fuel, this submarine can achieve surface speeds of 12 knots to 15 knots, and submerged speeds of up to 24 knots, carrying a crew of 95.

    Apart from Arihant, the K-4 will also arm another Arihant class submarine INS Aridhaman which is currently under construction along with two others. These submarines will have eight launch tubes each.


    How nervous is Pakistan? I think the Pakistani's have come to the conclusion that they can no longer go toe-to-toe with India in a conventional fight. That is the reason for their alliance with terrorist groups. They can only fight an insurgency...any direct conflict will lead to the destruction of the govt.

    India is becoming interesting Cool

    INS Arihant undergoing sea acceptance trails: Top Navy official

    Post  Pinto on Mon Apr 18, 2016 9:38 am

    Country’s first armed nuclear submarine, INS Arihant, is currently undergoing sea acceptance trials, a senior Naval official said on Sunday.INS Arihant is now undergoing sea acceptance trials as it had already passed several deep sea diving drills, Flag Officer-Commanding-in-Chief, Eastern Naval Command, Vice-Admiral HCS Bisht told reporters here.

    “The submarine will be commissioned after completing all the sea-trials,” he added.INS Arihant, a 6,000-tonne submarine, is country’s first indigenous nuclear submarine and can launch nuclear weapons from underwater.

    The vessel was built under the Advanced Technology Vessel Project at the Ship Building Centre here.

    Stating that India Navy has presently adequate strength of ships, submarines and manpower, Bisht said 45 ships are under-construction in various shipyards in the country.

    The Navy had successfully conducted the International Fleet Review with the support of various agencies including the Andhra Pradesh government and the Vizag district administration, he informed.

    To a question, Vice Admiral Bisht said the Indian Navy’s warship INS Viraat will be decommissioned this year and it will be converted into a maritime museum.After decommissioning the ship will be handed over to the Andhra Pradesh government,” he added.

    Meanwhile, the local MP, MLAs and several residents sailed on-board the Eastern Fleet ships and witnessed various Naval exercises as part of the ‘Day at Sea’.Eight ships including the indigenous stealth frigate INS Satpura, fleet support ship INS Sakthi, Landing Platform Dock INS Jalashwa, Landing Ship Tank(Large) INS Airavat, Missile Corvettes IN Ships Kanjhar and Nishank, Inshore Support Vessels T-36, T-39 and submarine INS Sindhukirti of the ENC participated in the event, a defence release said.

    INS Arihant, India’s only indigenous nuclear submarine, to debut as soon as May

    Post  Pinto on Wed Apr 27, 2016 8:20 am

    INS Arihant has completed all trials and weapon launch tests, and is soon going to be inducted in India's Navy fleet.

    This is a big fillip to PM Narendra Modi's Make-in-India campaign as INS is India's first indigenously developed nuclear armed submarine.

    Top government sources said Modi is likely to announce the formal induction in the Indian Navy anytime soon.

    Sources said the induction of this 6000 tonne plus indigenous nuclear submarine should coincide with the completion of Modi government's two years in office on May 26.

    "The submarine has passed all deep water and other tests and is ready for induction. It is just a matter of time that its formal induction (which is closely being monitored by the Prime Minister's Office) will be announced," said a source close to the development.

    With the induction of INS Arihant, India will join one of the few super powers in the world that possess the knowledge of designing, engineering and operating a nuclear submarine.

    Arihant is the lead ship of the five nuclear powered ballistic missile submarines launched in 2009.

    Built at Vishakhapatnam, Arihant has been designed, developed and engineered by various agencies including the Defence Research and Development Organisation, the Department of Atomic Energy and the Submarine Design Group of the Directorate of Naval Design, besides private companies such as Larsen & Toubro (L&T).

    As against a conventional diesel-electric submarine, nuclear submarines have the capability to stay out at sea longer and without the need to come up to the surface.

    Arihant draws its design from design consultations with Russian design bureaus and possesses capabilities to be equipped with short range missiles as also the K4 long range ballistic missile.

    "The indigenous nuclear submarine has passed all major tests," sources said.

    India currently operates Russian-origin nuclear-powered submarine INS Chakra, which it leased for 10 years from Russia in 2012. However, the INS Chakra does not carry nuclear weapons.

    Arihant-class SSBN

    Post  Pinto on Wed Sep 14, 2016 7:58 am

    India and Russia will undertake advanced discussions this week on the leasing of a second nuclear attack submarine which have been ongoing for a while.

    An Indian delegation is heading to Russia in the next few days to carry out talks on the issue, official sources told The Hindu.

    On Tuesday, External Affairs Minister Sushma Swaraj and Deputy Prime Minister of Russia, Dmitry Rogozin chaired the 22nd session of the India-Russia Inter-Governmental Commission on Trade, Economic, Scientific, Technological and Cultural Cooperation (IRIGC-TEC) setting the agenda for the summit-level meeting between Prime Minister Narendra Modi and Russian President Vladimir Putin next month.

    Russia has already leased an Akula class nuclear attack submarine to India for 10 years as a package deal along with aircraft carrier Vikramaditya which was commissioned into the Indian Navy as INS Chakra in 2012.

    Informed sources said that while Russia has offered another Akula SSN on lease, India is interested in a different and a newer class of boat. Officials expressed hope of concluding a deal very soon.

    Submarines are considered the most potent offensive military platforms. While conventional diesel-electric submarines have limited range and endurance, nuclear powered submarines are free of such limitations.

    Powered by a nuclear reactor which gives virtually unlimited range and endurance, the submarines can silently traverse oceans hunting for enemy vessels. Nuclear submarines are of two types, nuclear attack submarines (SSNs) and ballistic nuclear submarines (SSBN).

    SSBNs are specifically meant to carry missiles armed with nuclear warheads and assure a nation’s second strike capability if attacked first by nuclear weapons.

    India’s first SSBN Arihant powered by a 83 MW ncuelar reactor has been under sea-trials since 2009 and is all set for commissioning. At least two more boats of the same class are in various stages of construction.

    Indigenous SSNs

    In February last, the Cabinet Committee on Security (CCS) has approved the design and construction of six SSNs domestically. By the approval, the government had converted part of the ambitious 30-year, 24 submarine building plan from conventional to nuclear.

    The plan is to design and build an indigenous SSN based on the experience gained from Arihant and they will be built at the same Submarine Building Complex in Vizag.

    The programme is on track and the design phase is progressing as per schedule, officials said without elaborating further.

    Senior Navy officials had in the past expressed confidence that they would be able to reduce the timelines for such a complex project which typically takes about 15 years.

    Indian Navy currently operates thirteen conventional submarines and one nuclear attack submarine leased from Russia. In contrast, China operates five SSNs, four SSBNs and over 50 conventional submarines.

    The second Indian nuclear submarine was launched

    As the Indian magazine India Today reported (almost a month after the event), on November 19, 2017, in the atmosphere of secrecy in the Indian state shipyard Ship Vuilding Center (SBC) in Vishakhapatnam, a second Indian nuclear submarine of national construction was launched, name Arighat. Completion of the ship is carried out in a closed berthing complex-SBC. It is planned that the boat will enter the Indian fleet in 2020-2021. The descent was carried out in the presence of the new Indian Defense Minister Nirmala Sithamaran.

    Nuclear submarine was damaged after water entered its propulsion chamber

    Indigenous nuclear submarine INS Arihant has suffered major damage due to ''human error'' and has not sailed now for more than 10 months, say sources in the Navy.

    Arihant is the most important platform within India’s nuclear triad covering land-air-sea modes.

    Arihant’s propulsion compartment was damaged after water entered it, according to details available with The Hindu. A naval source said water rushed in as a hatch on the rear side was left open by mistake while it was at harbour.

    The Ministry of Defence did not respond to questions from The Hindu.
    The accident

    Since the accident, the submarine, built under the Advanced Technology Vessel project (ATV), has been undergoing repairs and clean up, the sources said.

    Besides other repair work, many pipes had to be cut open and replaced. “Cleaning up” is a laborious task in a nuclear submarine, the naval source said.
