Sir,In Hazia only the hull is fabricated rest of the sections have to be fabricated at SBC only.
For 2nd and 3rd boat hull is more or less ready.

ATV 2 and 3 will most probably use 2 reactors (VM-4 indian type).
With submerged displacement around 10,000+.

Delta class subs of RuN use the same reactor with similar displacements.

PM to launch indigenously-built nuclear submarine on July 26

21 Jul 2009, 1630 hrs IST, PTI

HYDERABAD: The Eastern Naval Command at Visakhapatnam is gearing up for a unique milestone in India's defence history on July 26 wherein Prime
Minister Manmohan Singh will launch the indigenously-built nuclear-powered submarine that is tentatively named INS Arihant.

July 26 is celebrated as 'Vijay Diwas' which marks India's triumph over Pakistani intruders in Kargil. Launch of the indigenously-built nuclear-powered submarine has been planned for July 26 to coincide with Vijay Diwas. A host of Navy and defence officials are expected to grace the occasion.

Though the Navy authorities haven't yet officially confirmed the programme, Andhra Pradesh Chief Minister Y S Rajasekhara Reddy announced the Prime Minister's visit to Visakhapatnam after a meeting with the latter in New Delhi late last week. A senior Navy official told PTI over phone from Visakhapatnam that everything related to the event was being taken care of by Navy higher officials in New Delhi.

"Right now we have no information about the event as such," the Navy official added. Said to be built under the Advanced Technology Vessels (ATV) Programme at a cost of 2.9 billion USD at the Naval Dockyard in Visakha patnam, the 6,000-tonne submarine will be put on sea trials for two years before being commissioned into full service. In the two years, the submarine will also undergo harbour trials of its nuclear reactor and other systems.

India previously used a leased Russian-built nuclear submarine INS Chakra under then Capt R N Ganesh from January 1988 to January 1991.

With the launch of the indigenously-built nuclear-powered submarine, India will join the exclusive club of US, Russia, China, France and the UK with similar capabilities. The ATV will give India the additional power of a nuclear weapon strike from the sea, apart from surface and air which it currently possesses.

The ATV has been developed jointly by the Indian Navy and the Defence Research and Development Organisation (DRDO). The nuclear reactor of the submarine has reportedly been developed at the Indira Gandhi Centre for Atomic Research, Kalpakkam, while the vessel is based on the Russian Akula-I class submarine.

Atv-2 & 3 will have only one reactor .no design changes will occur in these boats.these boats has lots of resemble on atv-1 and based on the study and analysis carried on atv-1 changes will be under taken on atv-4 & 5.

prashanth · Post by **prashanth** » 25 Jul 2009 20:31

But, will that not make the subs underpowered? It is reported that ATV 2 and 3 are larger than ATV-1.

guys, if there's going to be anything on TV please let us know beforehand so that we can catch it. I surfed for sometime and only found some cricket stuff.

pkduva, appreciate the inputs. and congrats on being associated with such a ground-breaking project !

prasanth, he says no design changes, then why would those be larger ?

Thanks Boss for the wishes. I want to share more but i want all the spies to keep at bay let them not know anything about our boat.

We did face lots of problem in between,its not an easy job bacause the testing procedures itself are rigorous and believe me executing job for atv-2 and atv3 is taking my skin off my job but anything for the nation.

We have learnt lots of things and it will help in executing next job.Its normal for us after atv-1 we have already shifted our focus on atv-2 & 3 and we are trying our best standardization so it will be easy for us to launch it in an quick time.

Read the article on the Arihant in the latest INDIA TODAY. Says that the Arihant will carry 12 K-15's but only 4 K-X(Agni-III) SLBM's. But wait- the bigger monsters are coming

:):)

Article also states that " In 2005, the UPA Government gave an in-principle clearance for building a follow-on series of larger ballastic missile submarines (SSBNS), costing nearly Rs-8000 crore a piece or nearly twice that of the current series of ATVs and another line of nuclear-powered fast attack submarines(SSNS) to escort them.' If you need money, you'll get it,' the then finance minister P.Chidambaram had assured the project team."

Snippet on Manmohan Singh in the same article:
Supervises the final phase of ATV construction. Enlarges te N-Sub programeme with sanction for building of a new class of SSNs and SSBNs based on Russia's Akula class for a projected fleet of 10 N-subs over the next 20 years.

Arun , any significance of Higher Tonnage ? As i understand a higher tonnage would translate to lower underwater speed all things being equal.

pkudva , wouldn't the real challenge start now , since the trials hasn't even started and its a new design , all needs to be tested and validated in real conditions.
Although ATV 2 and 3 will be batch production , but will IN wait and see how the trails of the first ATV goes before moving to 2 and 3 ?

Please accept my congratulations for being part and achieving this milestone for our nation

PM to launch INS Arihant in Visakhapatnam tomorrow

Prime Minister will arrive at the ENC's airbase INS Dega in Visakhapatnam by a special IAF plane along with his wife at 11 am and drive straight to the Naval Dockyard to commission INS Arihant into the sea.

This news report says its 6000 tonne vessel

Well, 6000 ton was my original estimate (allowing for A3 Sl over the base Charli II). However, if it is 6000 ton, then the lenght will be the 110m I estimated and not the 104 or so that Sandeep Unnithan had suggested. The boat will be too "full" otherwise with a much higher block coefficient , wont be efficient at all and will require much higher power than what is available to have even a half way decent performance.

So only one of the two can be right. (6000 ton and 110 /112 m) OR (5000 ton and 104M)

Sir,please i have not designed the sub nor know what more is inside the sub except for some things. We are supposed to do our job and thats what we do.If Navy chaps come to know that this guy is more busy in knowing things which are related to us then they dont answer.It has happened to me in the past so now a days, i have stopped that practice on asking these people about the electronics and missiles that are going to be in the sub.

with respect to congrats,again i have not manufactured the sub so all wishes should go to the technicians and engineers who have worked 24X7 to make it into a reality.My only suggestion is that atlease let us not criticse them saying that they have delayed.

But believe me guys, because of stadartization,lots of idgenenous things have been developed and which is helping us a lot.

pkudva · Post by **pkudva** » 25 Jul 2009 21:42

It is a challenge as i have mentioned in the past because most of the systems which had been tested long back will now be put to use and there will surely be trouble shooting and people in the SBC,Private firms,DRDO chaps, BARC chaps are good enough to solve them. Tensions will always be there but once this atv-1 is commissioned believe me guys the next line of strategic subs will be ready for India.

ATV is of mega monster value to India, and there is no room for criticism for when it touches sea waters. Everything has a right time and this is the right time for Arihant.

My deep gratitude to every one who has collectively worked to make it happen, including the menial sweeper and porter. Including all supporting companies that made parts and pieces.

I liked that sure Arun.
Next time i will convey my message to all of them.But one more thing is that people in SBC know abour Bharat Rakshak as i conveyed it to them about us and they are happy that there is one forum which supports them badly.

All i can say i will give details in general,but no details in depth pls as its all about our nations security.Hope RAW will not catch me and put me behind the bars

Just to add to the earlier comment, PTI also mentions ATV as a 6000 ton sub. Again, everybody glue onto your TV sets and login to BR from 11 am.

The above is the first line of the Jaina navkara. It will be cool if the next ATV will be named "Siddha - the accomplished"!

The nation deserves a huge congratulations, launching its own boomer!! This is an immense effort and for that I would say "Namo Sidhayanam", my bow to the accomplished [everybody who worked on ATV]

There may be speed difference of less than a knot with that tonnage diff.
There should be "moored" trials first while the sub is still at the pier, then builder's tests in open sea (took 20 days for Borei), then state acceptance trials after which the boat is officially introduced. First of Lada class has been tested for more then 3 years now.

This is all mind blasting onlee.....

I have surfaced to periscope depth after 6 months of being hunted in the ocean depths by the faltering economy....must submerge again soon...just hoping to catch a glimpse of what we have all been waiting for so long...Congratulations to all the defence agencies, research institutes, and production agencies...

Advance congratulations are also in order to our "balls of steel", "mr clean", "the poet", and "chota" prime ministers of the past and present... who would have thought you had it in you.

Being inducted on the holy day celebrating Subramanya Swami is indeed ominous symbol of what is to come.

As this is the first of its type, there will be lots to learn from it for future variants. While doing my undergrad at RPI back in the 1990s, I did a summer program funded by DARPA and Electric Boats on distributed engineering mockups (this was the era when the 777 was also fully mocked electronically before it was built). They were trying to build submarines without having to go through the deep pain of the first in the class. They would use these systems to do a VR walkaround on the sub, for example to check in the engine room if the "mechanic" (or whatever they are called) would have sufficient space holding a wrench or other tools on the equipment. They could see with the VR mockup if there was clearance or not. Apparently before this the first and second of the boat series were "custom" and standardization occurred only later down the production run. As this was in the mid 1990s, you can only imagine what the DARPA boys are doing today.

Arihant's enemies are not only just India's enemies, but also the citizens of India who doubted the ability of the indian scientist and engineer to deliver.

In that respect, The Arihant is here to destroy a lot of myths, and half truths.

Godspeed

Dive into future: India goes nuclear, under water

The 5,000-ton vessel will be armed with 12 nuclear-armed K-15 ballistic missiles which have a 700 km range.

The K-15s will later be replaced by 3,500 km-range K-X missiles.

India’s first n-submarine to be launched today

The ceremony will take place in a small, covered dry dock where the submarine has been assembled and will be attended by the Prime Minister, Defence Minister A K Antony and Navy Chief Admiral Sureesh Mehta. This will be the first time that the highly secretive project will be revealed before the public. While a small contingent of media personnel will attend the ceremony, a strict ban has been put on photography.

Gagan · Post by **Gagan** » 26 Jul 2009 04:53

This means no mobile phone cameras. Come to think of it, even mobile phones are banned when the PM is around.
But this means that some Veteran Doordarshan cameramen, from the DD Kendra Vizag, with their semi colored and out of focus camera will be doing the honors.

Oh the horror. He is going to capture all the VIP's faces. Just like Doordarshan cameramen simply have to shift to showing the VIP enclosure when the military hardware passes by at the R-day parade.

Bumbling idiots, bloody civilians, I say.

T.S. Subramaniam report in the Hindu
Nuclear submarine all set to enter waters

The mini-nuclear reactor that will power the submarine has been fitted into its hull. “The reactor can be operated and maintained,” said another BARC scientist. Highly enriched uranium will power the reactor which has a capacity of 80 MWe. This enriched uranium has come from the Rare Materials Project, an undertaking of the Department of Atomic Energy (DAE), situated at Ratnahallai, near Mysore...The boat is about 105 metres long and is a joint product of the Navy, the BARC and the DRDO
