I have doubt in case of a war, can we use INS Chakra or Nerpa against the enemy country in limited way for defensive or fully offensive?

There was no agreement to limit the use of this submarine. We can do what ever we want with it for 10 years. Russia doesn't put these limitations on us like USA.
(but remember Russia did not give us any missiles on the Nerpa with more than 300 KM range (missile technology control regime)

well take this with a pinch of salt (Check the author ):

Chief of naval staff admiral Nirmal Verma had said last year that Arihant would be inducted into service two years after its launch.

But the submarine's reactor is yet to be started. Nerpa was supposed to join the navy as INS Chakra in June 2010, but will now join only towards the end of this year. The delay is affecting the training for Arihant.

Is India planning to have 6 SSBNs? 3 arihant class and 3 larger ones and do you think the later subs will be the size of the british Vanguard class subs and how many missile tubes do you reckon they will have?With the arihant having 4 tubes for the upcoming Agni-3SL, I think the larger SSBNS will have 12-18 missile tubes!!

Quite true. Future subs (nuclear/conventional) will have larger armament to hold missiles like K-X, K-15, Brahmos(I/II). However, successful Desi SLBM tests are necessary before that. Maybe after ARIHANT induction we can see K-15 tests. That will actually conclude Indian Nuclear Triad to send chilling waves mainly across east. Follow on Arihants will be larger to carry Indian ICBMs ready to launch.

you are true about K-X and K-15 type of missiles.
but Brahmos I-II are or can also be fired from Torpedo tubes, because both of are not more then 300km range,
K-15/ Sagarika has atleast range of 800-1000km.......
K-X is Agni-II/III modification will have 200okm or above. this will be most propably in VLS version of the sub's,
may be at present Arihant will only have K-15 in VLS tubes.

According to bharat rakshak the Agni-3SL is set to have a range of 5200km which can be fired from the Indian ocean against China if necessary.Do you think India in the future will be developing an SLBM with a range of 9000km ( I'm not dreaming but that is what I speculated).I mean the longer the range the better palcement of SSBNs- India's second series of SSBNs will be way larger than the arihant class probably the same size as the british Vanguard class sub(SSBN).I think having a 5200km and 9000km SLBM will be an advantage for India as these weapons will make good strategic weapons against her enemies!!

We will never know what exact range our longer range missiles will have. But I can say for sure that the successful test of 5500Km missile should be seen as the 8000Km-9000Km ranged missile. Warhead reduction is inversely proportional to the range of missile.

Our ICBMs will be developed to craft of SLBM versions of same in advance. Still first we need at least few good SLBM launches from desi Subs.

Yes, Brahmos I-II can be fired from torpedo tubes but you always know the importance of VLS versions of same. At present Arihant-I should be considered as TD but the actual size of sub is believed to be larger than what is declared. What missile config it has is still unknown. I am so waiting for K-15 tests after the Arihant-I's induction.

A 5000 to 6000 km SLBM's range missiles are more than enough for India. That is if China specific. Any launch from Bay of Bengal to Malaca straits can reach anywhere in China.

New here , my first post . Just wanted to ask if we are developing any nuclear attack subs . and if so when are they expected ?
also do we have the Tu22M backfire on lease ? as wiki says so but i cant find any mention of it on any Indian defense sites .

what you asking is our state secret.

Tu22M backfire may be may be not let others be guessing, BTW we paid tons of money for AC then again negotiated the contract, you may speculate where that money gone too.

India building reactors for nuclear submarines | Defense | RIA Novosti

Work is in progress on India's nuclear steam reactors for its first nuclear powered submarine, Srikumar Banerjee, head of the country's Atomic Energy Commission, said.

Last year, India floated out its nuclear-powered submarine, the Arihant, to be powered by a light water reactor (LWR) using enriched uranium as fuel.

In an interview with The Hindu published on Monday, Banerjee said the "nuclear steam supply system" was 100% ready.

"We are only waiting for other systems to become operational so that we can start the commissioning activity of the reactor. I really do not know when the harbor trials will be done."

The Indian Navy needs three or four nuclear-powered submarines to be a viable force.

Enriched uranium for these submarines will come from the Rare Materials Plant at Ratnahalli, near Mysore, Banerjee said.

so what world was telling is right that arihant was without reactor. so how it is floating in water i mean what is powering it. when we are going to install nuclear stem reactors. whats time frame . is int future testing has to be carried out once nuclear reactor has been installed in it. what if
that nuclear reactor didn`t work properly

Buddy, I don't think we need SLBMs or even ICBMs beyond the range of 8,000 Km at all. That range would cover all of China from top to bottom as well as all radical countries from Pakistan to possibly Middle East (who knows the future? Middle East is bonhomie with Pakistan other than Israel). Making anything beyond that would antagonize Europeans and Americans and even Russians for no reason. Not that we've to be scared or anything but what's the point of making such an expensive weapon when we have no enemies in that part of the world? All our threats are just within our reach already and around us.

I think DRDO should cap the SLBM/ICBM program range limit at 8,000 Km... at least for now, while keeping further options open.
