Indian nuclear submarines

Thanks for the suggestion.

how?A 700km missile weapon which only test once and even failed at the end of the test,conventional sub is such a diffcult job india didnt try before ,but you try to make a n sub ,india has 209sub for years, india shuld make a conventional sub first,is that a better way?

Who told you K-15 Sagarika has failed. It has been tested 6 times and it didn't fail so far. Get your facts right.

India already has the technology to make nuclear reactors, so it went to make nuclear subs first. In future, with ToT from Scorpene deal, India will make its own conventional subs.

Any news regarding the trials of ATV & about its nuclear reactor.....?

Remember the HDW 209 subs were built in Mazagon docks hence we already have built conventional subs.

Sorry xixihaha but the level of secrecy maintained in the ATV project bars us from any valid information to share with you.

But I believe that the model in the inauguration ceremony was without any reactor due to precautionary measures.

i dont think ATV was without reactor at inaugration.................what do you expect ...........a) to cut out hub of atv to place reactor or assemble reactor in sub.( ..............this must be the way things work in china:bye:

This is a report by IANS.

'If any of you are under the impression that it made contact with water with an actual reactor fitted inside its hull you are mistaken,' the scientist told IANS.
The scientist echoes a report in Defence Professionals Daily, a German online publication, which says Arihant 'currently is little more than a floating hull' without nuclear propulsion or weapons systems. The scientist, who did not want to be named as he was not authorised to speak to the media, was clarifying media reports implying that Arihant is propelled by nuclear power and that India has become the sixth nation to operate nuclear subs.
'I think the media did not correctly report what was told to them by the Bhabha Atomic Research Centre (BARC), or the officials deliberately did not want to be explicit beyond a point,' he said.

Nataraja Sarma, former BARC physicist and co-author of 'Nuclear Power in India: A Critical History', says it makes safety sense to first check out the seaworthiness of the basic submarine without the reactor core and then assemble the reactor.
'Once big components like reactor vessel, heat exchangers and the lead shielding (for protecting crew from radiation) are transferred to the submarine before closing its shell, the remaining smaller components including the fuel assembly can be introduced later to complete the construction,' he said.

India's nuclear sub doesn't have working reactor yet - AOL India News

even if you negate the first quote, contest for the second quote, Mr. Nataraja Sarma had clearly stated that it would be more convenient to check the seaworthiness without the reactor critical.

what do you think of a launch of a submarine with out being slipping it into sea waters or without the dock being flooded.

Technically such a launch means not a full fledged launch of the vessel but a formal/official launch

There is nothing to be ashamed about it mate, we should learn to walk before we run, the news would be more weird if it would have stated that we have a fully operational reactor in the sub with K-15 SLBM delpoyed.

[sayareakd]

If pakistani and Chines want to think that INS Arihant is sub without nuclear reactor and missile, then all i can say is that it is their privilage to think that way, we cannot do much about that, if that is what makes them happy........

But ask any military person who has got knowledge about the subject and he will tell you what that kind of platform means for India........

Recent reactions from Pakistan and China point out to this fact.

We Indians knows what we got and we are happy about the same.

try and realize that not having a reactor and not having a functional reactor are two different things .......................

'Once big components like reactor vessel, heat exchangers and the lead shielding (for protecting crew from radiation) are transferred to the submarine before closing its shell, the remaining smaller components including the fuel assembly can be introduced later to complete the construction,' he said.

I do agree I don't have the precise information

but how can u contest that there is a reactor inside????

aahhh sarcasm!!!

this should help

no sarcasm mate please don't take the argument otherwise,

what is your point?

 

[s_bman]

no sarcasm mate please don't take the argument otherwise,

what is your point?

the point i am trying to make is that it is difficult to place large components of a reactor after hub has been sealed, so most of components should be in place if not all.............having critical fully functional reactor loadedwith fuel is seperate matter

Maybe their is a power plant inside which has not gone critical or the sub is not sealed at all. not many source says that the dock was flooded which usually is perform in a launch ceremony.

Who told you K-15 Sagarika has failed. It has been tested 6 times and it didn't fail so far. Get your facts right.

6 times?????

 

[Daredevil]

6 times?????

Check this

Final test of K-15 ballistic missile on Tuesday

Work on the missile started around a decade ago under a highly classified programme earlier called Sagarika (Oceanic). Development ran parallel to the Indian navy's 25 year programme to build its own nuclear-propelled submarine, the ATV. In the last few years, the missile remained behind a veil of obsessive secrecy with the government refusing to confirm or deny its existence. Variously dubbed 'the naval missile' and the 'navalised Prithvi', it was successfully tested to incremental ranges six times. The last successful test to its full range was in April last year.

There is a reactor in the sub. You cannot build a Nuclear Submarine without the reactor. If that is the case, then the hull will have to be cut open to install the reactor. Not possible...waste of time and money.

The scientist probably means the hull which we saw during the ceremony was probably a mock up of the real one. Then I doubt the IN would have made a big deal out of that.

The reactor is there and so is the fuel. But, it is still a year or 2 away from going critical.

exactly my thoughts
