INS Arihant - reactor active, running on nuclear power now

In a major step towards completing its nuclear triad, the atomic reactor on-board the indigenous nuclear submarine INS Arihant was activated late Friday night and the submarine is on its own power now. The submarine will soon be launched to sea on the Eastern coast for extensive sea trials

DRDO has also readied a medium-range nuclear missile BO-5 for being deployed on the Arihant and its last developmental trial was held on January 27 off the coast of Vishakhapatnam.

INS Arihant, till now, was being tested in the harbor on shore-based, high-pressure steam. With the reactor going critical now, the submarine will eventually head for open waters for extensive "sea- acceptance trials", which will include firing of its 750-km range K-15 ballistic missiles.

The sea trials will take at least another 18 months before INS Arihant can become fully operational. It will be the first ballistic missile submarine to have been built outside the five recognized nuclear powers — the United States, France, Russia, Britain and China.

Sections of a second submarine, to be named Aridaman are already at an advanced stage of outfitting at the Ship Building Centre (SBC). Sources indicate Aridaman could be launched by next year. Sections of a third submarine are also under construction at the Larsen & Toubro's Hazira facility. The three SSBNs have been under construction under a secret navy-DRDO-Bhabha Atomic Research Centre (BARC) project called the 'Advanced Technology Vessel' (ATV) project. 

India's strategic plans call for a fleet of five nuclear powered attack submarines (SSN) and five ballistic missile submarines (SSBN).

INS Arihant SSBN completes Harbour Acceptance Trials

Navy Chief Admiral D.K. Joshi's has disclosed that the nation would soon get to hear good news on Arihant submarine. It is believed that the reactor will go critical, setting the stage for sea trial sometime in the first half of 2013. 

Admiral Joshi said harbour acceptance trials for INS Arihant have been completed, sea trials are expected to begin early next year. If everything remained in place, the submarine is expected to be ready for induction by late 2013. It will be one of the most significant achievements of country's submarine building capability.

The submarine will be fitted with K-15 submarine launched ballistic missile which is under development. The trials of 700 km K-15 missile have already been carried out. While Arihant's induction is being eagerly awaited, the navy has fully integrated recently acquired Akula class submarine from Russia. INS Chakra is on ten year lease.

The navy is also working on a new base near the Andhra Pradesh coast for its nuclear submarines. The project Varsha, has been going on for more than two years now. It will be one of the most prominent facilities in the eastern coast. The western coast already has a new base at Karwar in Karnataka.

Some of the new naval assets are now being deployed on the eastern coast strengthening the fleet with modern warships and submarines.

Progress on Indian SSBN - INS Arihant

An image, taken by GeoEye’s satellite 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 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. 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.

The movement of 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: INS Chakra. 

It is thought that the Arihant is equipped with less than a dozen launch tubes behind the conning tower for nuclear-armed ballistic missiles. Arihant is expected to become fully operational by early 2013. It is expected that India might be building at least two more SSBNs, and one of which is being rumored to be named as INS Aridaman .
