Indian Navy soon to get latest Sonar systems for anti-submarine warfare

[kaku1]

Are these latest sonar present on INS visakhapatnam??

Yes for all destroyers and ASW platforms. Including Kolkata.

Aircraft carriers dont tow these cables..

From when Vizzy become aircraft carrier?

Aircraft carriers dont tow these cables..

Sir ins visakhapatnam will be India's lethal destroyer when inducted into IN..Its far advanced that INS KOLKATA.
Its not A/c

What is that on the nose of the ship?/ ( black colour one)

Its an anchor.

Yes for all destroyers and ASW platforms. Including Kolkata.


From when Vizzy become aircraft carrier?

I got confused with INS Vishal.

Its one word mistake . Submarine

New Delhi: India will get six low frequency Active Towed Array Sonar (ACTAS) systems, that will be fitted on the Kamorta-class submarines, later this year from Germany.

The system, which can detect enemy submarines, will give a fillip to India's anti-submarine warfare capabilities.

Defence council clears purchase worth ₹850 crore

An advanced system developed by a consortium of Indian Defence laboratories led by the Thrikkakara-based Naval Physical and Oceanographic Laboratory (NPOL) to defend naval ships against torpedo attack will now be integrated on as many as 30 ships operated by the Indian Navy.

While 11 ships will be equipped with the full system, named Maareech Advanced Torpedo Decoy System, the remaining will get just the torpedo countermeasure capability that’s part of it.

Acquisition cleared

The Defence Acquisition Council, led by Defence Minister Nirmala Seetharaman, on Tuesday cleared acquisition of the anti-submarine warfare (ASW) and non-ASW variants of the system which will be manufactured by Bharat Electronics. Initially, systems worth ₹850 crore will be acquired to arm warships.

Two systems are already functional on INS Ganga and Gomati which were used for user evaluation trials of the indigenously-developed systems.

“The survival capability of a ship is greater if the attacking torpedo can be detected early and also at a range equal to or more than the escape range of the platform under attack. A fully integrated Maareech system has both torpedo detection and countermeasure capability,’’ said R. Rajesh, NPOL scientist and spokesperson.

Tactical advantage

‘‘Also, the system offers tactical advantage by classification of the torpedo along with localisation and target motion parameters. The escape solutions are then evolved which will advise the crew of the ship on the most appropriate manoeuvre and countermeasure actions necessary to defeat the threat,” said Mr. Rajesh.

Besides the NPOL, Visakhapatnam-based Naval Science and Technological Laboratory was involved in developing the system. The torpedo defence sonar that is part of Maareech was developed by a team led by project director K. Ajith Kumar, NPOL scientist.

Major milestone

S. Kedarnath Shenoy, NPOL director, said that the induction of Maareech would be a major milestone for naval research and development as it would be the first time the indigenously designed towed array sonar system would be arming Indian warships.

With this, the NPOL has now successfully developed multiple configurations of sonars such as hull mounted sonars for ships, submarine sonar systems, towed array sonars and airborne dunking sonar systems for the Navy.

Indian Navy Deep Submergence Rescue Vehicle (DSRV).

The Indian Navy had acquired such vessel when it possessed only four submarines in 1971. But the vessel was decommissioned in 1989. Since then, the Indian Navy procured DSRV along with the number of submarines in its fleet has increased.

DSRVs like INS Nistar, that figured in the Indian Navy's fleet, have the capability of rescuing the crew of a disabled submarine by using a wet or a dry escape method, avoiding the problems associated with decompression.

According to Commander (retired) Sudarshan Chakrapani who served on submarines of the class as INS Sindhurakshak and INS Sindhuratna said the Indian Navy's submarine arm came into existence on December 8, 1967 with the commissioning of INS Kalveri. Four years later, the Indian Navy acquired the submarine rescue vessel INS Nistar. "In 1971, the rescue vessel was inducted in the Indian Navy when we had just 4 submarines. Today, we have many more submarines, but even rescue vessel," he said.

The search for a new submarine rescue vessel commenced after INS Nistar was pensioned off in 1989 said Chakrapani. For a 'make-do' solution till such a vessel is inducted, the diving tender Nireekshak, which has the all-important diving bell that enables rescue of sailors succeeded her. However, INS Nireeshak has its own limitations. The Indian Navy, therefore is without any 'worthwhile' method rescued sailors onboard a sunken submarine, said Commander Chakrapani.

In a development that perhaps comes a little too late vis-a-vis the recent mishaps, a senior naval official claimed that the ministry of defence after the August 2013 mishap of INS Sindhurakshak (which had claimed 18 lives) cleared the proposal for procuring two Deep Submergence Rescue Vessels at a cost of Rs 1,500 crore.
