Indian nuclear submarines

[sayareakd]

Nirbhay test from Arihant most probabaly will be false reporting .

SLCM variant being first test fired from the Arihant even before from a submerged pontoon or other vessel is too much to believe ........ or else they have tested it secretly before .

Lot of tests are not made public, even the K15 last official test was made public rest 14 tests were never made public.

 

[Yumdoot]

And thank god for that. Otherwise we would have been told that DRDO cannot do it and so let us import.

Now the MTCR et al are also very receptive considering the progress we already are making.

You just cant import a nuclear submarine, Last time Russian did it at the height of cold war, when Indians made believed Russians that having another nuclear submarine in India Ocean will only add to the American worries. Later they did not extend the lease.

Such type of Platform and weapons systems are not for sale. We are not going to give it to any one and no one is going to give it to us. That is why DRDO was tasked with making them.

Arihant successfully test fires dummy missile

New Delhi. India’s first nuclear powered nuclear attack submarine, Arihant, has successfully test fired a dummy missile.




According to reliable sources, the vital first test in ejecting a missile from its onboard silos was conducted November 25. Proverbially, adding a feather to the cap of the Indian Navy and scientists from DRDO and BARC, the firing was done remotely from a far away location by the Strategic Forces Command (SFC), India’s nuclear command authority which is tasked with creating nuclear deterrence.

To mention more achievements, the indigenous submarine has also successfully completed the critical diving tests, and significantly, met nearly all its design and designated parameters just about 100 per cent, including the maximum possible power option tests.

It is actually good news all over, but the last one final step before the submarine is inducted as INS Arihant formally in the Indian Navy will be the firing of proper missiles albeit with unarmed warheads. Details are unavailable but this should happen soon enough as there are indications of the submarine taking part in the International Fleet Review (IFR) being held by the Navy in February.

The boat should be operational by then, sources told India Strategic.

The missile fired was a dummy version of DRDO’s B 5, which approximately has a range of 1000 km. Later, missiles with a reach of 3500 to 4000 km, are likely to be inducted onboard.

India plans to build some half a dozen Arihant class, in line with the country’s nuclear doctrine which calls for No First Use but Massive Retaliation if attacked.

Arihant is built with Russian designs, but this will be the country’s first nuclear powered nuclear attack submarine, classified in international naval lingo as SSBN.

India has one more nuclear powered submarine, INS Chakra, leased from Russia, but that cannot fire nuclear missiles. The classification for such boats is SSN.

Like any submarine, both INS Arihant and INS Chakra are pearl shaped to accommodate the vertically launched missiles, and designed to move faster underwater than on the surface. They can stay deep in the darkness of the oceans for months, the only restrictions being the limits on human tolerance and availability of nuclear fuel.

It may be recalled that the project for nuclear submarines was sanctioned soon after the 1974 nuclear test by Prime Minister Indira Gandhi but it suffered when Morarji Desai and VP Singh took over as Prime Ministers in the coming years. In 1983, Mrs Gandhi pushed the project once again with required funds, but it was in 1998, when India conducted the second round of nuclear tests, that Prime Minister AB Vajpayee sanctioned the project afresh, and a decision was also taken to involve the private sector. Larsen & Toubro, India’s premier engineering construction company, was involved right from then onwards.

L&T, as it is known, has done commendable work in gradually and systematically building a horizontal supply-chain base and meeting the DRDO and naval specifications. DRDO, or Defence Research and Development Organisation, has been in-charge of the India’s missile systems programmes throughout, which it has delivered with distinction. Nuclear propulsion systems have been installed and managed by experts from BARC, or Bhabha Atomic Research Centre.

Indications of Arihant’s journey have been coming out for some time, and recently, Chief of the Naval Staff Admiral Robin Dhowan mentioned the possibility of its inclusion in the IFR in rather positive terms although he did not understandably commit.

The tests are done one by one, and for a nuclear boat, every single check is critical. Deployment has to be thoughtfully and carefully, even if it takes time as safety and success are both paramount.

Notably, in IFR, only operational ships and submarines can and will take part.

The India Strategic extends Best Wishes to the Indian Navy, DRDO and BARC scientists.

Anybody saw Aridhaman?
or indigenous SSN Class?

 

[rohit b3]

Anybody saw Aridhaman?
or indigenous SSN Class?

Indigenous SSN class is still on papers.

 

[tejas warrior]

Anyone having updates for INS Aridhiman ?

When can we expect it in indian ocean ?

 

[Scarface]

Does anyone know the specs of the reactor in Arihant ?
What is the expected amount of operational time before having to refuel ?
Is it as good as Russian/American SSBNs which can go a decade without refuelling ?

Is it at least half as good , considering it's our first indigenously built N-reactor

 

[harish.kaks]

Is INS Arihant participating in IFR 2016 ??

The reason why the yard that built Arihant is located deep in a secretive locale is precisely to protect information such as the stuff you're asking. :biggrin2:

What I can tell you about the reactor is that it is rated at 83MWe.

 

[Gessler]

Is INS Arihant participating in IFR 2016 ??

No. Freaking. Way.

Even if it was operational it wouldn't come there. Each of the 50 foreign navies visiting would each steal a part from it if it shows up.

 

[aditya g]

The commissioning is more important than parade in IFR.

Everytime we hear a date it is tied to some event Navy Day 2015, 15th Aug, 26th Jan, etc and last heard it was IFR 2016. Now IFR is upon us I hope they will commission it at least when Pronob da is President

Anyways I do hope Arihant is featured in the IFR. It could be done on the sidelines by requesting the President to visit the SBC dry dock as well.

Same for the second boat- INS Aridhaman, it was also to be launched last year in October but still not happened.

 

[bengalraider]

As of now the commissioning of INS ARIHANT and launch of INS ARIDAMAN is both scheduled for the third quarter of this year.

There were reports that it would be commissioned during the IFR.

Commissioning in third quarter?

 

[warrior monk]

whatever little is available publicly Arihant reactor model 86 Mwt around 44000 SHP with modestly enriched fuel of around 40 to 45 % U 235

 

[warrior monk]

There were reports that it would be commissioned during the IFR.

I think it will be wrong to unveil it especially with so many foreign navy present and any sophisticated submarine with passive sonar systems, such as towed array of hydrophones can ascertain the SL level of our SSBN , propeller cavitation signature ,engine and pump noise of ATV so it is not advised.

 

[abingdonboy]

Journo asks a question about whether INS Arihant will be at the IFR and if not why not (44.25):


CNS: "you wll not see Arihant at IFR"

Perfect answer, no need to induldge these drama queens in the media and give away details regarding strategic projects.

Good decision.
It's better to hide the sub instead of giving its SONAR signature and design to 52 countries' 200 warshipswarships just for flaunting.
