Indian nuclear submarines

[sayareakd]

Wooowwwww....

We need to think on tuning our manufacturing processess...

Question, If we are seeing the stern, from where does the propeller shaft emerges??

If we are seeing the Bow, these ships do not have torpedo tubes??

Thank You!!!

One curious thing that struck me, They have named one submarine as Agamemnon!!! probably they will sell to Greek

Interview with Avinash Chander, DRDO

Q] When will you integrate the K-15 missile into Arihant?

ANS] The K-15 integration in Arihant is already in progress. As soon as Arihant's sea trials are completed, its weapons and armoury will be integrated"¦ just waiting for the trials to be completed. The reactor on board the submarine has attained criticality. The DAE [Department of Atomic Energy] has done a fantastic job in building this reactor. It is a good example of the cooperation among the DAE, the DRDO and the Navy. Similarly, the cooperation has been fantastic among the DRDO/ the ADA, the IAF and HAL [Hindustan Aeronautics Ltd] in building the LCA. The LCA made more than 450 sorties this year in spite of the prolonged monsoon. Till last year, the LCA flew 260 to 280 times. It shows the integrated, cooperational agreement among the three agencies. HAL is now building up its capacity to produce the LCA at a fast pace.

WOW!!!!!!!!!! three at a time...............

looks like a GI JOE factory or something

INS Arihant to undergo sea trials soon | idrw.org

.......... Its reactor went critical in August last year, and we thought it was entering Sea trials right then..

Now after 6 months they are saying that it "will start" sea trials in a few months?? really?

Now i see why we always import..

This confidence about finally achieving its dream of deploying a nuclear-powered submarine armed with nuclear-tipped ballistic missiles — called a SSBN in military parlance — is reflected in the naval Republic Day tableau this year. It depicts models of INS Arihant and a submarine-launched ballistic missile (SLBM).

Maybe this time sea trials are with weapons. There is a difference, you see. My guess.

BTW, pls see this article:

"We expect INS Arihant to finish its harbour trials in a few weeks, a month or so, and then head for sea trials. All its capabilities will be tested as the third leg of the triad, the sea-based strategic deterrence, which will include firing of its ballistic missiles," said assistant chief of naval staff (submarines) Rear Admiral LVS Babu on Tuesday.

It is our first attempt at nuke sub, they take it for spin in harbor. Safe hai. Read it some place that they are waiting for Russian rescue vehicle. Plus every system needs to be checked then check again and again.

 

[arnabmit]

Boats are subjected to 3 type of tests. Each takes about 6 months.

HATS = Harbor Acceptance Trials
SATS = Sea Acceptance Trials
WATS = Weapons Acceptance Trials

Total with data review in between trials = 2yrs. This is for lead class of a new platform.

Derivatives take about 3 month for each trials (total 1yr).

Subsequent boats of the same class take about 1 month for each trials (total 6 months)

Indian Navy to conduct INS Arihant sea trials in a month

New Delhi: In a move that will pull India a step closer to achieving the "nuclear triad", Indian Navy is all set to start sea trials for its first indigenously-built nuclear-powered submarine INS Arihant in few weeks, Assistant Chief of Naval Staff Rear Admiral LVS Babu said on Tuesday.

A miniature model of the prestigious subamrine will also be flaunted as a part of Indian Navy tableaux at the Republic Day Parade.

INS Arihant's commissioning into the Indian Navy, which is expected till the end of the year, will gift India with the "nuclear triad", that is the ability to retaliate to nuclear strikes from land, air and sea-based systems.



Sea trials for INS Arihant will be the next major milestone for the submarine, which went critical on August 10, when the nuclear reactor aboard it was activated.

The submarine has successfully completed its harbour acceptance trials and is now set to be taken into the sea, said Assistant Chief of Naval Staff Rear Admiral LVS Babu .

"INS Arihant will provide us with the option for sea-based strategic deterrence, the third leg of the triad," Assistant Chief of Navy Staff (Submarine) Rear Admiral L Sarat Babu told reporters.

India which maintains a 'no first-strike' policy regarding the use of nuclear weapons, will be armed with a strong deterrence power and second strike capability by INS Arihant, which has stronger underwater endurance power and speed double that of the counterparts. It can dive into depths and remain their for a longer time. Other submarines, which are now being operated by Indian Navy need frequent trips to the surface for charging of the batteries.

But the nucleaar submarine being powered by a nuclear reactor fares much better.

The submarine that cost Rs 15000 cr, has been manufactured at the naval dockyard in Visakhapatnam by collaborative efforts of the Indian Navy, Bhabha Atomic Research Centre (BARC) and the Defence Research and Development Organisation (DRDO).

Though 60% of the submarine's body is indigenous, Russians too have assisted in designing it.

Last year, India became only the 5th country to have successfully developed its first submarine-launched ballistic missile (SLBM), which will be tested from INS Arihant.

Other than India, four other countries US, Russia, France, China and the UK have the capability to launch submarine-based ballistic missile strikes.

[sayareakd]

Hindu says that go ahead for third boat of ATV class is not given. That is somewhat strange as GOI though PM as already given go ahread for more nuke subs long ago.

If Arihant cost 15000 crores then it must have included cost of capital goods for manufacturing sub. Future subs of Arihant class will cost much less.

Get ready to deploy underwater nuke-deterrent - Hindustan Times

India's first indigenous nuclear-powered ballistic missile submarine, Arihant, will head for "comprehensive sea and weapon trials" within a month, a big leap towards the country completing its nuclear triad — the ability to launch strategic weapons from land, air and sea, a navy official said.

The 6,000-tonne Arihant is moving closer to kicking off patrols, armed with nuclear warheads, this year. China's newest submarine-launched ballistic missile (SLBM) Julang-2, to be deployed on the Jin-class (Type 094) boats, is expected to attain operational capability this year. The JL-2 SLBM is expected to have a range of 7,250 km, more than that of the missiles to be fitted on the Arihant. The Indian submarine will be equipped with the K-15 missile, capable of delivering a nuclear warhead up to 750 km.

 

[AVERAGE INDIAN]

It was reported in bharath rakshak a while ago the Type 094 class boats are as noisy as Soviet submarines of the 70s.

Some sources claim that these Chinese ballistic missile submarines were plagued with various problems and design flaws.

where as arihant is much more modern when compared

This is really strage !! What we have heard from media & other forums that there are atleast 3 more hulls are in the making or various stages of fabrication. As ATV Arihant class as series suppose to have six subs in total as per earlier reports & discussions.

ndia's first domestically constructed nuclear submarine INS Arihant is to undergo sea trials in the next few weeks.

The submarine is undergoing harbour acceptance trials phase, and will then be launched for sea trials that are likely to be completed by the end of 2014.

Press Trust of India (PTI) cites navy staff (Submarine) chief assistant, rear admiral Sarat Babu as saying to reporters that the Indian Navy will provide every possible assistance and support during the extensive trials for the first of class submarine.

If this has happen then it is sad news, it was like assembly line at L&T and other at SBC, (from the available material on net) they used to get pre-fabricated hull structure from L&T and assemble at SBC and then install all the systems inside.

May be this news is not true, they can surely find money for this and political will is not lacking for ATV project.
