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


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.

India had late last year signed a contract for the towed array sonar with German firm Atlas Elektronik.

Under the deal, the first six systems would come from Germany and the rest will be manufactured in India under cooperation with Bharat Electronics Limited.

"This system, which will arrive in the next few months, is a huge capability enhancement of our anti-submarine warfare. ACTAS is the backbone of anti-submarine warfare," defence sources said.

The towed array sonar provided by ATLAS permits observation of the sea space at ranges considerably above 60 kilometres, depending on the propagation conditions of the water.

This gives the sonar an operational range that by far exceeds that of radars and the weapons range of submarines.

The system is, therefore, not only ideal for hunting submarines but also for the wide-area reconnaissance of surface combatants.

"Indian ships currently use bow mounted sonar or hull mounted sonar which is less effective. ACTAS is the future," the sources said.

They added that the system is first being put on Kamorta-class anti-submarine corvettes. The project is destined to be rolled out to various classes of ships including Delhi, Talwar, Shivalik and Kolkata.

The sources said ATAS is especially vital in the Arabian Sea.

Warships detect submarines with sonar - a "ping" of sound emitted into the water that reflects from submarines, just as radar bounces back from aircraft.

In Arabian Sea's warm and shallow waters, the returning signal often gets lost, the sources said, adding that since ATAS is towed by a cable deep below the surface where submarines operate, detection is much higher.

Concept
The ATLAS ELEKTRONIK Active Towed Array Sonar (ACTAS) is a low-frequency ASW sonar system that operates simultaneously in active and passive modes and provides high-resolution target detection. The detection ranges of ACTAS exceed the weapons range of hostile submarines, thereby denying the enemy an offensive capability. ACTAS provides excellent performance up to very long ranges, which includes over-the-horizon surveillance.

It is designed to detect, track and classify

  • Submarines

  • Torpedoes

  • Surface vessels, including speed boats
ACTAS(Active Towed Array Sonar) belongs to the generation of new and advanced ASW sonar systems, which comply with today’s naval requirements to counter the ASW threat by deploying high-transmission-level low-frequency sonar equipment at variable depth to achieve long-range submarine detection. The Active Towed Array Sonar System ACTAS is designed to support ASW operations against small, silent submarines over long ranges and in difficult sonar environments.


Main Features
  • Transmitter with high source level and bandwidth

  • Coverage of entire 360° panorama, allowing simultaneous target detection and Doppler measurement from all directions

  • Hydrodynamic optimised towed system for high-speed sonar operations in deep and shallow waters

  • Robust and safe Winch and Handling System

  • Long acoustical array aperture to cover the important information in the low-frequency band

  • BITE and back-up functions

  • Performance prediction function

  • Bi- and multistatic operationTransmission of various pulse types for detection and classification (moving/stationary targets)Active and passive operation in parallel

  • Automatic torpedo warning function

Read the flawed report here first:

Are these latest sonar present on INS visakhapatnam??

Yeah I know But @ashok321 was saying kamorta class submarines..that was confusing..

Thats pretty..:cheers: its paty time..:D
