Mumbai, March 18 Amara Raja Group's specialized engineering R&D firm, Amara Raja Design Alpha (ARDA), announced its entry into the mission-critical defense electronics space on Wednesday, stating that it has developed an indigenous Power Conditioning Cabinet (PCC) for naval sonar systems.
The company said it will expand in the next phase to include the design of power amplifiers, signal interfaces, and power amplifier cabinets, helping to build a comprehensive indigenous ecosystem for naval sonar systems.
This initiative represents a significant contribution by a private sector technology company to India's growing efforts to indigenize its naval capabilities.
Approximately 61% of the system's components will be indigenous, enabling around 40% cost efficiencies through advanced power engineering and local manufacturing.
The Indian Navy's budget has grown from ₹49,623 crore in 2020-21 to over ₹1,03,548 crore in 2025-26, reflecting India's expanding investment in maritime capabilities, the company said.
Within this framework, sonar systems form a critical layer of underwater surveillance and anti-submarine warfare across the Navy's fleet, it added.
"We are excited that our expertise in electronics and power system design and manufacturing can directly contribute to our nation's defense systems. This development reflects our commitment to building deep, long-term capabilities in strategically important technologies alongside India's defense research institutions," said Suresh Nair, Managing Director at ARDA.
ARDA said that the units developed by the company will comply with global standards, ensuring reliability in demanding naval environments.
The PCC will support loads up to 160 kW, delivering stable, high-reliability power distribution for sonar systems, where acoustic detection equipment requires extremely high power quality during sustained maritime operations, it added.
