Atlas Elektronik Partners CFF Fluid Control for Indian Navy’s Indigenous Sonar Project

Indian Navy

New Delhi: Atlas Elektronik GmbH – a division of the German submarine and shipbuilder thyssenkrupp Marine Systems (tkMS) has partnered with CFF Fluid Control Ltd to supply 12 indigenous low-frequency variable depth sonar systems for the Indian Navy.


Through shipbuilders Garden Reach Shipbuilders and Engineers Ltd and Cochin Shipyard Limited, these advanced towed sonars are set to be integrated into Indian Navy Anti-Submarine Warfare (ASW) vessels.

Atlas Elektronik has previously supplied active towed array sonars to the Indian Navy, demonstrating the effectiveness and reliability of their technology. Thus, the technology for these sonar systems is not entirely new to Indian waters.

The partnership between Atlas Elektronik and CFF Fluid Control Ltd aims to enhance the operational capabilities of the Indian Navy’s front-line platforms by leveraging proven technology and localised production. A significant aspect of this partnership is the production of these sonar systems in India by CFF Fluid Control Ltd, aligned with the Indian Government’s objective of achieving self-reliance in defence manufacturing. Through domestic production of these systems, the partnership not only strengthens India’s defence capabilities but also promotes local expertise and job creation.

CFF Fluid Control Ltd specialises in the manufacture, overhaul, repair, and maintenance of mechanical and electronic equipment, including navigation, communication, and weapon systems for Indian Naval submarines and surface ships. Their expertise extends to reference systems and test facilities encompassing pneumatic, hydraulic, electrical, and electronic systems.
