Is it the same submarine or is it more than 1??

I stand corrected! Holy mother of God! Three nuclear submarines! (2 Arihant class, 1 Chakra class or 3 Arihant!)??

I am very happy that they have been able to keep media mouths shut for so long about these projects. The hitjob in The Hindu not withstanding, media has also been disciplined in keeping wild speculation under control.

 

[Kshithij]

India has 3 submarines - 2 Arihant class submarine and 1 Akula Class submarines. Unless one can say why the third nuclear submarine is Indian and not Akula, I won't be convinced

You not being convinced bothers no one. believe what you will

No matter who you are , no matter what kind of journalist you deal with , throw some money on their face that will help them to seal their lips.
Or
Send a team of 6 armed with deadly AR and nab that CEO , tie him to pillar and tell him that take money or else get ready to take bullet. And cause of his death's blame will go to naxals.
Dude there are thousand way to deal with a douchebag / A-holes. Its matter of balls are you willing to do it or not.

I have a stupid question..
I heard than people working around nuclear reactor will be exposed to some kind radiation even though taking precautionary measures and suits. And that will have huge impact on off springs of these people genetically. Is true?

Well if that was to be the case scientists at BARC should have turned zombies by now. There are safegaurds in place. But yes if radioactive materials leaks then there is a problem. But people and workplace are periodically if not daily scanned for radioactivity. Infact people at barc are scanned daily.

Lol. Nopes .
Usually any person (even a labourer at civilian Nuke reactor) near nuke reactor will be using gieger counter to measure radiation dose. A sufficiently thick lead cladding separating the reactor will absorb most radiation.

And a little radiation does no harm. Even we were exposed to a bit everyday and in hospitals too (some medical instruments have them). Just that if a persons gieger counter does show more than permissible exposure than its time to maintain distance .
Visited a BARC reactor during college trip didn't convert to a dinosaur

Stop posting pic of exact location. Pic of sub will do, only if something of interest is visible. Lets not get too much attention. Let them keep doing their job.

Its not like some member on this forum using google maps is going to know something the ISI doesnt. Those foreign agencies who are trying to collect intelligence on this will know a lot more than any of us here. Lets not forget the Chinese have their own spy satellites and are probably passing on everything they know about us to the pakis.

True.
I hope we got our own satellites over chinkis bases.

 

[Chinmoy]

Come to think of it, we got more than three nuke subs, so we dont have space to park them.

well said.......

They have radation meters to monitor them. Here.

'' Researches in remote control started in 60's at Central Research Institute for Automatics and Hydraulics (Moscow). "A wire line was adopted basing on simultaneous doubled paying out of cable from two spools located in torpedo and towed by a submarine. Such telecontrol system was applied in SET-53M type torpedo commissioned in 1969 under the index TEST-68. In 1971 torpedo TEST-71 was designed on the basis of more advanced torpedo SET-65; then – torpedo TEST-71M and helicopter-based remote-controlled torpedo VTT-1 on the basis of torpedo AT-1" ("60 years of CRI Gidropribor", St. Petersburg, 2003).

In contrast to western telecontrol systems providing both directional and depth control of several torpedoes for maximum consideration of hydrology, decreasing of torpedo's noise, and alteration of target class (for example, while submarine's "dolphin jump" surfacing), telecontrol system of our Projects 641B and 877 diesel electric subs provided only horizontal guidance of only one torpedo. Submarine-towed telecontrol spool is still used. Influence of water currents on torpedo's speed leads to spool curling and wire breakage. Application of long conducting ropes to decrease this effect excludes use of telecontrol at shallow depths and makes multiple launches impossible.

Late 60's Western designers developed umbilical telecontrol spool; after launch, it remained on breech door of torpedo tube. Cable slippage was provided by protective "hose" to compensate submarine's post-launch maneuvering. Umbilical telecontrol enabled to increase reliability of cable connection, reduce limitations in speed and maneuvers, and ensure multiple launches including those at shallow depths. Consequently, torpedo weapons became more effective, and distances between launch site and targets were significantly increased.

In 70's Soviet Union also had everything to adopt umbilical spools; however, the Navy hindered that innovation. The necessity of post-launch removing a spool and a "hose" from torpedo tube required manual operations. Navy Technical Development Plan involved automatic reload of torpedo tubes which was possible only with towed spool. So, the Navy rejected "hose" telecontrol systems; moreover, it was widely believed that "we don't need it", since our subs and torpedoes were less silent and so forth. USET-80, basic torpedo of 3rd generation nuclear submarines had never obtained homing system prescribed in Technical Development Plan.

By the way, in real conditions even brief telecontrol considerably increases effectiveness of torpedo launch against submarine; moreover, successful launch against surface ships performing anti-torpedo zigzag maneuvers at a distance over 11-13 km is possible only with telecontrol. The main thing is that up to mid-80's telecontrol remained the only effective interference resistance method in conditions of high sonar countermeasure. Till early 80's there were no homing systems with required interference resistance worldwide. So to provide effective fire, the US Navy has been using telecontrol as indispensable condition since 50's; their surface ships are equipped with broad range of ASW means to maintain capability of multiple attacks upon submarines.

All Western heavy torpedoes and even new Chinese torpedoes use umbilical telecontrol. Towed spool applied in our torpedoes is a 50-year old rudiment. In fact, this places Russian subs in the crosshairs of enemy's weapons having much more effective firing range.

The situation is that, for example, none of Russian torpedoes presented at international defense show IMDS-2009 had umbilical telecontrol spool, even the most advanced UGST! Only towed spools... ''



This is an extract from an article i found online, it discusses the flaws of Russian torpedoes. Since a majority of our torpedoes are Russian, are our torpedoes too limited by the same problems?

If our torpedoes are limited by the same problem, what procedures/tactics are used to minimise this handicap?

Also, are the Ship and sub launched versions of the varunastra limited by the same problem?

A New almost ready Conning Tower is visible on Google... guess another sub is going to hit water soon,

 

[sayareakd]

Looks like bigger one coming.........................................must be star.

 

[captscooby81]

Who know this one might be INS Chakra one remember it got damaged in coning tower the last news we heard ..or is this for new Boomer ?

edit : that image was of 06-09-2017 ..which is close to 7 months old ..might be of the Akula as the accident was reported some time in september last year

You don't need to cut out the entire conning tower to repair it ..... Also , we don't know if the news about Akula getting damaged was even authentic or not .

arihant is s2...3 more submarine s..
arighat ,s4,s4*....being built. .

13000. tonne s5 class will be built
