'India's secret N-submarine project nearing completion'

[bugger]

Does the Indian sub... work?

So far everything India has made, Agnis, Nags, Nagins, Trishul, LCA, Arjun... all didn't work. Only time will tell how well does this work and if the Navy even orders more of these.

Who made this? DRDO?

C'mon man, no need to be so green-eyed about the Indian weapons, atleast we dont buy them of the shelf and claim them to be ours...
I know the grapes must be feeling sour but still no need to bad mouth eh

Jako, It's still going to take 2 years of testing before it becomes operational. They're still not done testing the nuclear reactor of a nuclear submarine.

In typical Indian fashion this 2 year timeline may still be elongated.

It is going to make around 3-4 years as per Indian fashion.

and goi has already allocated the money($2.9billion) reqd for another 3-5 atvs.........which itself talks of the huge success of the atv project,otherwise why would goi invest money in a project which is not fully proven yet!!?......this actions talk a lot bout the atv

The project is very huge but we have always prove that we delay in execution but slowly things are changing and hopefully project will be finish within 2 years.

launching/firing unsuccessful missiles , adding/changing new systems on arjun are truly very different as compared to testing something while sitting in a nuclear powred sub

Indian media video on the launch -

Indians made it with help from Russia.

Soon Pakistan will launch its nuclear sub too with help from Chinese friends.

That's not the submarine which was launched yesterday.

Chinese quality are worst. Just copy the plan and implement on home with the best quality.

 

[Awesome]

dear asim,the operationilisation of a submarine is very much different from that of artillery divisions or missiles as you can see......the procedure followed is quite different........so unlike the ones i mentioned,you can term the atv a successfull project,as of now.....,yes you are right bout the fact that,weapon testing would only be done two years from now........and till now everything has gone just fine,so there is no need to speculate atv..........and btw,can you clear up what you were saying bout the nuclear reactor of the atv......thnx

Abdul rafi posted an article a few posts back about the nuclear reactor still being under a test phase.

I agree the whole scenario is different. This project even more difficult than the Arjun, LCA, etc. So can India pull this off, after those failures? Maybe it can but one would always question it until proven otherwise.

First go and lean about Nuclear Subs before come here and discussion,

you know what is Nuclear reactor goes critical means ? Prob not, first go and then come.

 

[mughaljee]

Many things , many peoples are saying,
my concern is only this, what we will do now, or should do now ?

Everyone taking Arjun issue whenever Indian's defense is discuss. I am sure they want other failure rather than their own's success. It would be best in Pakistan's interest to make Nuclear Submarine.

Relax....

Just go to this link and paste some information on their face.....

NPOL (DRDO Lab) developed sensors for INS ARihant

Many a heart at the Naval Physical Oceanographic Laboratory(NPOL), Kochi, would have swelled in pride when 'INS Arihant’, the country’s first indigenous nuclear-powered submarine, touched waters in Vishakahpatnam on Sunday. For, the eyes and ears of INS Arihant were designed and developed by scientist of the NPOL.

The sonar(Sound Navigation and Ranging) system installed on Arihant are a combination of two communication systems named `Ushus’ and ‘Panchendriya’. Panchendriya is a an integrated submarine sonar and tactical control system, comprising a passive surveillance sonar, a passive ranging sonar, an intercept sonar, an active sonar and an underwater communications system. Ushus is a new-generation sonar for `kilo-class’ submarines.

During the past two decades, the NPOL had given the Indian Navy an impressive 87 percent self-reliance in acoustic sensors for warships and submarines.

All the warships of the Navy, including ships acquired from foreign countries, are fitted with DRDO sonars like the APSOH, HUMVAD and HUMSA. Sonar is a technique that uses sound propagation(usually underwater) to navigate and communicate with or detect other vessels.

INS Arihant makes NPOL scientists proud

BARC developed PHW reactor for INS Arihant

CHENNAI: Atomic Energy Commission chairman Anil Kakodkar said on Sunday that the Bhabha Atomic Research Centre (BARC), by building the miniaturised reactor that propelled the country’s nuclear-powered submarine, had demonstrated “that we have our indigenous Pressurised Water Reactor (PWR) technology.” He called the launching of INS Arihant “an important milestone” in the Advanced Technology Vessel (ATV) programme. “This PWR technology is very complex. We have been able to compact this reactor and pack it in the cramped space” of the hull of the submarine, Dr. Kakodkar told The Hindu from Visakhapatnam where the submarine was launched.

The shore-based PWR has been working at Kalpakkam, 60 km from Chennai, for the past three years, he said.

India has been a world leader in building Pressurised Heavy Water Reactors (PHWRs) that use natural uranium as fuel, and heavy water as moderator and coolant. But this is the first time that India has built a PWR that used enriched uranium as fuel, and light water as both coolant and moderator.

Dr. Kakodkar said the BARC mastering the PWR technology was significant now, because the Light Water Reactors that India would be importing (from Russia, France, and the U.S.) were PWRs that used enriched uranium as fuel, and light water as both coolant and moderator.

To a question, the AEC Chairman said, “Yes, we miniaturised the reactor [on our own]. The basic complexity is that you have to make it into a compact power system to fit into a submarine.”

Srikumar Banerjee, BARC Director, also stressed that “the event marks the beginning of PWR technology in India.” The BARC made many design features to make this reactor compact. “There are novelties not only in the reactor’s design but in its manufacturing,” he said. For instance, the steam generator which drove the turbine to generate electricity, was compacted in a novel manner. The heart of the reactor is the steam generator.

Dr. Banerjee said: “A boat of this type is a major technology in itself. Its steam generator is yet another technology. The whole platform is a very complex combination of various technologies. That is why we are happy it has reached fruition.

“We have so far developed reactors built on the shore [on firm ground]. But a submarine is a moving platform. It is rolling and pitching, and undergoes other kinds of motion. Against these, we have designed and developed this compact reactor. This is a major achievement.”

Asked whether the Russians helped the BARC in miniaturising the reactor, Dr. Banerjee said, “No, no. They were consultants…Consultancy was done for the whole submarine, not for the power part alone.”

He denied that there was an inordinate delay in the programme. The ATV was conceptualised only in 1984. “This is a completely new technology. It takes time to develop.”
