India’s nuclear submarine to trigger arms race: Pak Navy
Monday, 27 Jul, 2009 | 02:52 PM PST |
KARACHI: Pakistan Navy's spokesman Captain Asif Majeed Butt termed India's nuclear-powered submarine a destabilising step which would jeopardise the security paradigm of the entire Indian Ocean region, DawnNews reported. ……………………….......
Captain Majeed said the induction of the new submarine could trigger a nuclear arms race and all littoral states, including Pakistan, will take safeguarding steps.

-shankarosky once again very very happy one more confirmation on the projected specs and one more step towards Mig 35 coming to puneOnce again the Russians helped, quietly.They provided equipment for two VM- 5 pressurised water reactors, one of which was assembled and tested at Kalpakkam’s Prototype Testing Centre in 2004.
The VM-5 reactor was the nuclear fission reactor used in a pair to power the Soviet Navy's Project 661 Анчар (Papa) second-generation submarine. It was a pressurized water reactor (PWR) using enriched uranium-235 fuel to produce 177 MWt of power.
NICE. Gives us an easier way of studying the noise signature of Chinki Boats (Fattas).NRao wrote: Do not worry. China IS dusting off some older nuke subs for Pakis.

The lower bound for sub's displacement is 8000 tons (provided it is 112m long)My calculations indicate the following:
- length: 110 m
Diameter: 11 m
Surface displacement: 6,000 tonne
Power: 85 MWthermal
True displacement: ~6,800 tonne
Max speed: 25 Knots
Surface speed: 13 Knots
The 11 m dia indicate that it can only take a 2 m dia missile with 1.5 stages. So the reports of 3,500 km range of K-X is correct. The key unknown parameter for K-X is what is the payload for which the range is 3,500 km. My calcs show it is for ~1,100 kg payload.

with akula 2 in water those boats will be lucky to survive 24 hours in water -let them give many -take the money and we shall make sure china get more business quickly and repeat business after that
it is like flying a F-86 against A su-30 there can be but one outcome -a quick trip to paradise
Damn you beat me to it! To my eye the outline most resembles the Yankee I/II class (Navaga) or Delta I/II class (Murena). Intuitively I would expect the Russians to share their earlier designs with India rather than a top-of-the-line SSBN. But we will find out over time.Gagan wrote:Shiv Aroor is no artist we now know.
But assuming he got the shape right, we are looking at a boat that looks more like a scorpene or one of the american subs as far as the sail design is concerned. Shiv doesn't show any angulation of the sail at all. The hump containing the VLS system is inadequately shown.
Some how I get the feeling that this might look like the old russian yankee class boat. The description is uncanny.

I'm expecting her as a multipurpose vehicle. Contrary to what be shown as cutaway pics by media, I'm expecting her have facilities for inserion of commandos and this SSBN designation it caries only for time being. Appropiate designation would be SSSMN. M for multipurpose.Kersi D wrote:WAHT DO YOU CALL INS ARIHANT ?
SSBM ? SSGN ? SSN ?
I think INS ARIHANT is perhaps the first submarine in the world to be a combination of SSBN AND SSGN.
Looks like we all have to create a new designation. SSGBN or SSBGN !!

If I can add, he just obfuscated the drawing. Borei has a streamline design for the hump and line drawing by Aroor shows its starting just after the conning tower. And he started caliming that to be Borei class. Either line drawing is wrong or his description is wrong.Gagan wrote:Shiv Aroor is no artist we now know.

The government will have to decide about Pakistan making its own nuclear submarine though the Navy is fully prepared to implement any decision taken by the government, the spokesman said.

Mr Aroor, if you have made this drawing yourself, then i must congratulate you. It is very true to the real design. It was a pleasure to meet all of you yesterday. Hope the govt can allow you to come again for the Arihant HAT phase to observe the same. Best of luck.

Thanks, but since we know that the US did not provide consultancy to the ATV project we can use logic to rule that out. We know however that the Russians did, that they are said to have earlier supplied drawings of the Charlie class and that according to a report based on an interview with the ATV project director 60% of INS Arihant is of foreign (presumably mostly Russian) origin.Singha wrote:similar problems produce similar solns. just because a sub looks like A,B,C doesnt mean its ==A/B/C.
except for typhoon class, almost all SSBN carry their missile tubes aft of the sail . the need to accomodate long missiles drives the extent
of humpishness. other than that, the sail shape (akula vs conventional), presence or absense of visible towed sonar pod, vertical or cruciform tailfins and hydroplanes on the sail or hull are common external features to all subs.
one could well claim Arihant = 688I + small hump if looks were all that mattered.
Sure, that is one aspect I did not think of.Kanson wrote:Sorry, i couldnt agree with that. Seems like he himself patted his back.comment on Shiv aroor's blog:

Second it.admins should lock this thread. no useful purpose other than time-pass is
being served at present. maybe a news thread for just posting news is what we need now.
the party is over.
