BHEL and DRDO’s DMRL Join Hands for Indigenous Production of Silica Radar Domes

Hyderabad / New Delhi, 1 September 2025 — In a major boost to India’s defence manufacturing, Bharat Heavy Electricals Limited (BHEL) has signed a Licensing Agreement for Transfer of Technology (LAToT) with the Defence Metallurgical Research Laboratory (DMRL), a premier establishment of the Defence Research and Development Organisation (DRDO).

The agreement enables BHEL to take up the production of fused silica radar domes, also known as radomes, using advanced cold isostatic pressing and sintering processes.

Why Radomes Matter

Radar domes play a critical role in missile systems by protecting seeker sensors from extreme environments while allowing unhindered passage of electromagnetic signals. They are indispensable for precision guidance in advanced missile technologies, making their indigenous production a strategic necessity for India’s defence sector.

Technology & Self-Reliance

DMRL, based in Hyderabad, is known for its expertise in advanced materials such as aerospace alloys, armor steels, and ceramics. By transferring this technology to BHEL, DRDO ensures that India reduces its dependence on imported radomes, in line with the ‘Aatmanirbhar Bharat’ (self-reliant India) initiative.

Market Response

The announcement has also boosted market sentiment, with BHEL shares gaining up to 2.5% on stock exchanges following the news, reflecting investor confidence in the company’s growing role in defence manufacturing.

Strategic Impact

This collaboration between DRDO and BHEL highlights the government’s focus on building domestic defence capability. With this step, India not only secures its missile systems with indigenous radomes but also strengthens industrial capacity for future high-tech defence programs.

Key Benefits of the Agreement:

• Enhanced Defence Autonomy: Indigenous radome production reduces reliance on imports.

• Industrial Growth: Strengthens BHEL’s role in advanced defence technologies.

• Economic Impact: Boosts investor confidence and creates high-tech manufacturing opportunities.

• National Security: Ensures reliable supply of critical components for missile guidance systems.

This LAToT between DMRL and BHEL marks a significant milestone in India’s journey toward self-reliance in strategic defence technologies, blending advanced research with large-scale industrial production.
