In a major step towards achieving allround ability to launch nuclear payload from air, land and water, a miniature 83 MWe pressurised water reactor (PWR), was fitted into INS Arihant and trials were conducted.The PWR is fuelled by highly-enriched uranium, which was developed with the help of Russians. The submarine was launched into the water last year and began its ‘sea acceptance trials’ (SAT) earlier this year wherein it was taken out of the harbour to conduct crucial trials.

“The nuclear reactor was fitted into the submarine for the first time some time back. Since it is the first time that India has built a miniature nuclear reactor for moving platform, it has to be tested when the submarine undergoes various kinds of motion like rolling and pitching,” sources said.
The challenge for Bhabha Atomic Research Centre was to make a compact reactor to fit into the 10-m diameter hull of INS Arihant (literally meaning slayer of enemies). The enriched uranium for the reactor comes from the Rare Materials Project, an undertaking of the Department of Atomic Energy, situated at Ratnahallai, near Mysore. With INS Arihant, India has become the sixth country after the US, Russia, China, France and Britain to have succeeded in constructing a nuclear submarine.

At the end of the trial Arihant will be given a nuclear regulatory authority certification before it could be deployed in the open oceans.As India has a policy of ‘no first use’ of nuclear weapons, a robust and survivable retaliatory strike capability is
dependent on this nuclear-powered submarine. This makes Arihant a shot in the arm for India’s nuclear triad. With its ability to remain submerged in the waters for infinite time, Arihant with its stealth can remain undetected by the army and can fire its nuclear-tipped missiles from under the sea.

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.

India enters nuke submarines club

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.

India's elusive nuclear triad will be operational soon: Navy chief

"INS Arihant is steadily progressing towards becoming operational…we are pretty close to putting it to sea (for extensive trials and missile firings)," announced Navy chief Admiral Nirmal Verma on Tuesday.


NEW DELHI: India's nuclear triad - the ability to fire nukes from land, air and sea - will soon be in place. After some delays and hiccups, the country's first nuclear submarine INS Arihant is getting ready "to go to sea" within the next few months.

"INS Arihant is steadily progressing towards becoming operational...we are pretty close to putting it to sea (for extensive trials and missile firings)," announced Navy chief Admiral Nirmal Verma on Tuesday.

"Navy is poised to complete the triad, and our maritime and nuclear doctrines will then be aligned to ensure our nuclear insurance comes from the sea. Given our unequivocal 'no first-use commitment', a retaliatory strike capability that is credible and invulnerable is an imperative," he added.

The Navy chief's emphatic statement comes a week after DRDO officially declared the country's first-ever SLBM (submarine-launched ballistic missile) or the K-15 missile, with a strike range of 750-km, was "ready for induction".

India has for some time possessed the Agni series of ballistic missiles as well as fighter-bombers to constitute the land and air-based legs of the triad. The long-elusive underwater leg, considered the most effective for both pre-emptive as well as retaliatory strikes, now finally seems to be taking shape with INS Arihant and its two follow-on SSBNs (nuclear-powered submarines armed with ballistic nuclear-tipped missiles).

The 6,000-tonne submarine, which has four missile silos on its hump to carry either 12 K-15s or four of the under-development 3,500-km range K-4 missiles, will head for sea only after its 83 MW pressurized light-water reactor goes "critical". So far, it has been undergoing systematic checks of all its sub-systems as well as "harbour-acceptance trials" on shore-based steam at Vizag.

With 46 warships and submarines being constructed, and another 49 in the pipeline under overall plans worth Rs 2.73 lakh crore, Admiral Verma said, "Today, I am confident we do not suffer asymmetries with anyone. We have the wherewithal to defend our maritime interests."

Brushing aside questions on the new US strategy to "rebalance" forces towards the Asia-Pacific as well as China's growing maritime might and assertiveness, the Navy chief said India's "primary" area of strategic interest lay between the Gulf and Malacca Strait, extending "down south to the Cape of Good Hope".

While India is not going to "actively deploy" in the contentious South China Sea, where China is enmeshed in territorial disputes with Vietnam, the Philippines and others, he said "all the players" there should ensure hostilities do not erupt in the region and hit global shipping and trade.

Turning to maritime terrorism, Admiral Verma said both the Navy and Coast Guard were now much better prepared and equipped to tackle 26/11-like attacks from outfits like Lashkar-e-Taiba. "Even before Abu Jundal (key 26/11 handler) said it, we had factored in such possibilities," he said.

"Terrorism from the sea and terrorism at sea are now realities of our times. In our external environment, one of our core concerns is the coalescing of the 'state' with 'non-state' entities," he added.

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.

and not even a single snap of the completed vessel :D. Great! Happy to see secrecy still exists

The Indian first nuclear submarine, INS Arihant originally planned for 2012 has been delayed further by one year.

Indian carrier, nuke submarine programs delayed:
NEW DELHI, India - India's key navy programs -- the indigenous aircraft carrier (IAC) and the nuclear-powered submarine INS Arihant -- are running late, according to local media reports Wednesday.

The aircraft carrier, originally scheduled for induction in 2015, has been pushed back to 2017, and the nuclear submarine, earlier set for operationalization this year, has been rescheduled for next year, said Indo-Asian News Service.

Indian Navy chief Admiral Nirmal Verma was quoted as saying Tuesday the aircraft carrier may not be inducted anytime before 2017 or so and the reason for the delay was the "set back" the project had over delays in gear box deliveries and a road accident involving a truck carrying the generators for the vessel.

However, Verma also claimed that India's nuclear triad -- the ability to fire nuclear from land, air and sea -- will soon be in place, once INS Arihant is put into the sea next year, reported local daily Times of India.

"Navy is poised to complete the triad, and our maritime and nuclear doctrines will then be aligned to ensure our nuclear insurance comes from the sea. Given our unequivocal 'no first-use commitment,' a retaliatory strike capability that is credible and invulnerable is an imperative," he was quoted as saying.

Sea trails are to validate the sub marine's under sea capabilities, without the reactor being utilized to its full capacity.

so how she is moving underwater during sea trials?

BTW sources say that the INS Arihant will now go to sea trials (reported on 7th Aug, 2012)

it means previous news i was referring to was wrong
