Reactor of India's first indigenous nuclear submarine INS Arihant goes 'critical'

NEW DELHI: The miniature reactor on board India's first indigenous nuclear submarine INS Arihant has gone "critical", which marks a big stride towards making the country's long-awaited "nuclear weapons triad," an operational reality.

Sources, in the early hours of Saturday, said the 83 MW pressurized light-water reactor attained "criticality" after several months of "checking and re-checking" of all the systems and sub-systems of the 6000-tonne submarine at the secretive ship-building centre at Visakhapatnam.

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.

When that happens, India will finally get the long-elusive third leg of its nuclear triad — the capability to fire nuclear weapons from the land, air and sea. The first two legs — the rail and road-mobile Agni series of ballistic missiles and fighters like Sukhoi 30MKIs and Mirage-2000s capable of delivering nuclear warheads — are already in place with the armed forces.

The capability to deploy submarine-launched ballistic missiles (SLBMs) is crucial since India has a declared "no first-use policy" for nuclear weapons, and hence needs a robust and viable second-strike capability.

Reactor Goes Critical, 1st Indian N-Sub Ready For Sea

Great news overnight: Its 83MW pressurized water reactor finally going critical, India's first indigenous nuclear-powered ballistic missile submarine Arihant is finally ready to leave harbour and enter a phase of sea trials in the Bay of Bengal.

With ballistic missiles and air delivery in place, the Arihant and its sister boats (India plans to build three, with the second hull already ready) will form the final leg of India's nuclear deterrent triad.

Congratulations too all scientists on the Arihant programme, Indian Navy DRDO, Dept of Atomic Energy and Shipbuilding Centre, Visakhapatnam. Shano Varuna!

So will IN going to produce about 6-8 of these???

As for current reports a total of 4.
INS Arihant
INS Aridhaman

other two yet to be named.

Although IN has acquired 1 Austin class LPDs but is there any possibility that India will look towards getting the remaining 11 more Austin Class LPDs from US along with 5 Tarawa Class LHDs from USA with Upgrades.

As all this can help them to put greater power in the Indian Ocean and may be beyond too.

Indian Navy was very much happy about the INS Jalashwa (ex-USS Trenton;the Austin Class LPD).

However chances are slim that we will go for further second hand ships of that class, as its purchase was a quick response to difficulties due to the lack of ambhibious platforms during 2004 tsunami.

INS Jalashwa is currently the third largest ship in service with Indian Navy and will become the fourth largest once INS Vikramaditya (ex-Gorshkov) enters into service.

We are planning to buy fresh ambhibious platforms from outside,upto 4 in number.

But it will be better for IN to have about 11 of the remaining LPDs from USA with upgrades along with 5 LHDs too as China or other conflict is near and these ships will be quite helpful in such regards. I think if some clever people in IN are present then they will hit a deal with USA very soon.

No, only 3 Arihant-class subs will be operationally deployed, the first one (S-1) was just a tech-demo
hull built before Arihant. Arihant is the S-2.

Yup, but why u mad bro?

Congrats to BARC, Indian navy DRDO and all fellow Indian, Pakistani and Bangladeshi Brothers. We will see a much batter version of Arihant shortly. Probably with 12 m dia. it will carry K-4 and Agni III SLBM with MIRV. It will be equipped with 180 MW reactor. It will have a lots of advance features. It will be much faster that Arihant. It will have long range Brahmos 1 and there after Brahmos 2. No ship or Aircraft career will be able to escape from its deadly missiles with 1 M CEP. A nightmare for enemy in the ocean.

Wow, India finally has its first nuclear sub after years of boasting about having one. Now, once a ballistic missile is fired from the sub, India will have the first test fire of its first SLBM, after all the tests on the pontoon. India is only the country in the world that boast about PLSM (Pontoon launched ballistic missile) being a SLBM.

 

[HariPrasad]

Wow, India finally has its first nuclear sub.

Yes Brother. If you can congratulate us, we won't mind saying thank you to you.

PM's congratulatory message, following the nuclear propulsion reactor on board INS Arihant, India’s first indigenous nuclear powered submarine, achieving criticality

Following is the text of Prime Minister Dr. Manmohan Singh's congratulatory message, following the nuclear propulsion reactor on board INS Arihant, India’s first indigenous nuclear powered submarine, achieving criticality.

I am delighted to learn that the nuclear propulsion reactor on board INS Arihant, India’s first indigenous nuclear powered submarine, has now achieved criticality. I extend my congratulations to all those associated with this important milestone, particularly the Department of Atomic Energy, the Indian Navy and the Defence Research and Development Organization.

Today’s development represents a giant stride in the progress of our indigenous technological capabilities. It is testimony to the ability of our scientists, technologists and defence personnel to work together for mastering complex technologies in the service of our nation’s security.

I look forward to the early commissioning of the INS Arihant.
