Kilo class sub upgrade

[sancho]

Not sure if this was posted before, but it's interesting anyway:

Fifth diesel electric submarine of Indian Navy is being modernized at Zvezdochka Ship Repair Center in Severodvinsk. The corresponding contract has been signed in Delhi, said Nadezhda Scherbinina, director of the shipyard's press service.

"Contract on upgrading INS Sindurakshak is for the first time signed without intermediary of Rosoboronexport", noted the shipyard's official. "Zvezdochka shipyard enjoys the right of independent foreign economic activity given by the President of the Russian Federation", she said. Modernization of Project 877EKM submarine INS Sindurakshak (stands for Sea Giant) will take 2-2.5 years. "The sub is planned to be delivered to Severodvinsk late June", said Scherbinina.

Being specialized in overhaul and utilization of nuclear-powered submarines, Zvezdochka shipyard has upgraded four Indian diesel electric submarines. The shipyard also continues repair and modernization of similar submarine INS Sindukirti in her basing site Vishakhapatnam, India.

All these submarines are Russian-made Project 887EKM (Kilo class) developed by Rubin design bureau, St. Petersburg. They are designed for antisubmarine and antiship warfare; defense of naval bases, coastal and sea lines of communication; reconnaissance and patrol operations. Such submarines have displacement of 2,300 tons; length of 72.6 meters; submerged speed of 19 knots (about 35 kph); test depth of 300 meters; crew of 52; endurance of 45 days. Armament includes six 533-mm torpedo tubes. In the course of modernization subs are equipped with advanced Russian Club-S cruise missile system with firing range of about 200 km, Indian sonars and radio communication systems.

Can someone give the details of sea to sea capacity? That is, range of (India) sonar, range of torpedos. At what distance can it lock at what kind of ship etc. All the details that we roughly know about aircrafts.

dude all these are classified. no countries reveal these capabilities. but our silent Kilo submarines became more deadlier now they carry latest sonars, communication systems, torpedo and long range missiles etc.

All the sonars developed by NPOL (DRDO). Those will also might be fitted on Akula-II and Arihant.

Thanx, but it doesn't gives what I wanted.

I just thought its a little odd, when we have detailed posters about radars and missiles. Things that we most expect to be operated in war. Surface to surface, surface to air and air to air. Even anti ship missiles. Land based, airbourne, all sorts of radars. But not sonars, torpedoes. Why the secrecy?

Hi saurabh, I also can't tell you the infos you wanted, because they are really hard to find and I think we don't have anybody from IN here, that could have some first hand knowledge.
The best source for infos about the sub is this (also with pics and a cutaway):
