Amara Raja Group enters Defence Electronics: Hyderabad, March 19, 2026: In a significant move towards strengthening India’s defence self-reliance, Amara Raja Design Alpha (ARDA), a specialised engineering R&D firm and a part of the $2 billion Amara Raja Group, has ventured into the defence electronics sector with the successful development of an indigenous Power Conditioning Cabinet (PCC) for naval sonar systems. This marks the company’s first foray into mission-critical defence technology, reflecting its expanding capabilities and commitment to supporting India’s growing naval indigenisation efforts.
The Power Conditioning Cabinet, a key component of naval sonar systems, ensures stable and high-quality power distribution for underwater acoustic detection equipment. Given the critical nature of sonar systems in modern naval operations, particularly in anti-submarine warfare, the PCC will support high-power loads of up to 160 kW, making it essential for sustained maritime operations in challenging environments.
A Milestone in Indigenous Defence Technology
The PCC developed by ARDA will feature 61% indigenous components, highlighting the company’s dedication to promoting local manufacturing and advanced power engineering. This strategic move is expected to result in approximately 40% cost efficiencies, underscoring the benefits of producing vital defence systems domestically.
ARDA’s contribution to India’s naval sonar systems is especially significant at a time when the Indian Navy is undergoing an extensive modernisation programme. With a defence budget increase from ₹49,623 crore in 2020–21 to over ₹1,03,548 crore in 2025–26, India is focusing heavily on enhancing its maritime capabilities, and sonar systems are pivotal in this drive. These systems form the backbone of underwater surveillance, anti-submarine warfare, and fleet security, with the power stability provided by the PCC playing a crucial role in their operational success.

Expanding ARDA’s Contribution to Defence Electronics
In the next phase of its development, ARDA plans to expand its efforts into the design of Power Amplifiers, Signal Interfaces, and Power Amplifier Cabinets, contributing to building a comprehensive indigenous ecosystem for naval sonar systems. This expansion aims to deepen ARDA’s involvement in defence electronics, further supporting India’s strategic objectives of self-reliance and technological sovereignty in defence technology.
“We are excited that our expertise in electronics and power system design and manufacturing can contribute directly to our nation’s defence systems,” said Dr. Suresh Nair, Managing Director of ARDA. “This development reflects our commitment to building deep, long-term capability in strategically important technologies alongside India’s defence research institutions.”
The successful development of the PCC will also contribute significantly to the operational efficiency and reliability of the Indian Navy’s sonar systems, ensuring the Navy maintains a technological edge in maritime warfare.
Compliance with Global Standards
The PCC developed by ARDA complies with international standards such as MIL-STD-901D (for shock resistance) and MIL-STD-461 (for electromagnetic interference/emissions, or EMI/EMC). These standards are critical for ensuring that the system operates reliably in the demanding and often hostile environments of naval operations. The robustness of the design guarantees the system’s ability to withstand the physical stresses of military-grade operations while maintaining optimal performance.
By meeting these standards, ARDA’s power conditioning solutions ensure that India’s sonar systems are not only reliable but also globally competitive, in line with the highest industry benchmarks for defence technologies.

Significance of ARDA’s Location and Ecosystem Collaboration
ARDA’s entry into defence electronics is also noteworthy due to its location in Infopark, Kochi—the city that is home to the Naval Physical and Oceanographic Laboratory (NPOL) of the Defence Research and Development Organisation (DRDO), India’s premier institution for sonar research and development. This proximity to NPOL presents a unique opportunity for collaboration, with ARDA joining the already established ecosystem of defence research in the region.
For decades, NPOL has been at the heart of India’s sonar technology programme, developing systems that are central to the Navy’s underwater capabilities. The emergence of a private-sector design firm like ARDA within this ecosystem not only strengthens India’s indigenous technology base but also aligns with the government’s ongoing push to encourage greater participation from the private sector in defence development.
The collaboration between private sector entities like ARDA and public sector research institutions like NPOL is expected to deepen, providing India with a more robust, self-reliant defence infrastructure that can meet both current and future challenges in the maritime domain.
The Bigger Picture: India’s Naval Indigenisation Drive
Amara Raja’s move into the defence electronics sector comes at a time when India is increasingly focusing on indigenising its defence capabilities. The government has committed to reducing dependence on foreign suppliers for critical defence technologies through initiatives like Aatmanirbhar Bharat (Self-reliant India). This shift is evident in the growing role of private-sector companies in key areas of defence manufacturing, from electronics to weapon systems.
The development of the Power Conditioning Cabinet is a direct contribution to this broader national effort, enhancing India’s capability to design, manufacture, and integrate advanced technologies that are vital to the nation’s defence. By developing such systems domestically, India not only strengthens its national security but also stimulates economic growth by creating jobs and fostering innovation in the private sector.
Strategic Implications for India’s Defence and Maritime Power
The introduction of ARDA’s Power Conditioning Cabinet comes at a time when India is expanding its maritime reach and capabilities. With the increasing importance of the Indian Ocean Region (IOR) in global geopolitics, India’s naval forces are becoming more critical in maintaining regional security and asserting maritime dominance.
In this context, modernising the Navy’s capabilities—especially its underwater surveillance systems, including sonar technology—is crucial. The Power Conditioning Cabinet will enhance the operational capabilities of these systems, allowing for more effective anti-submarine warfare and maritime domain awareness. These advancements contribute to India’s broader goal of ensuring maritime security and safeguarding its economic and strategic interests in the Indian Ocean.

Looking Ahead: Expanding Defence Electronics Footprint
As ARDA continues to expand its portfolio of indigenous defence electronics solutions, the company is poised to play a significant role in India’s defence modernisation efforts. The successful development of the PCC is just the beginning, with further innovations in power electronics and signal processing likely to follow.
This also signals a broader shift in India’s defence landscape, where the private sector is increasingly viewed as an essential partner in achieving self-reliance in critical technologies. The collaboration between Amara Raja, DRDO, and other defence agencies marks a new chapter in India’s defence indigenisation journey, one that holds promise for long-term strategic autonomy and national security.
Amara Raja’s entry into the defence electronics sector with the development of the Power Conditioning Cabinet for naval sonar systems is a major step towards building a self-reliant, indigenous defence ecosystem in India. By combining advanced engineering with local manufacturing, ARDA is contributing directly to the Indian Navy’s operational readiness, while also supporting the nation’s broader goals of defence indigenisation.
As India continues to invest in its naval capabilities and expands its maritime influence, innovations like the Power Conditioning Cabinet will play an increasingly crucial role in ensuring the country’s technological sovereignty and maintaining a competitive edge in the global maritime domain. With ARDA’s ongoing developments and future plans, India’s path towards becoming a self-reliant defence power is becoming ever clearer.
