• The Laser Science and Technology Centre DRDO’s lead laboratory for laser technology, is spearheading the project. While DRDO has previously developed a 25-kilowatt laser capable of targeting ballistic missiles within a 5-7 km range, this new initiative represents a significant leap in power and capability.

TROPHY Active Protection System

• In February 2025, Rafael Advanced Defence Systems Ltd of Israel and Larsen & Toubro (L&T) of India announced a significant collaboration at Aero India 2025, aimed at integrating the TROPHY Active Protection System (APS) into Indian combat vehicles.

• They offer 4D surveillance, enabling the detection and tracking of aerial targets, including fighter jets and slow-moving objects like helicopters and drones.
• This contract marks a substantial milestone in India’s pursuit of self-reliance in defence technology. With this order, BEL’s total order book for the current financial year has reached an impressive ₹17,030 crore.

Framework To Restrict Chinese Components

• MoD is finalizing a framework to eliminate the use of Chinese components in military drones, addressing national security concerns and promoting indigenisation.
• This initiative follows intelligence reports highlighting vulnerabilities caused by Chinese-made parts in drones used by the Indian Army, particularly in border areas.
• These components, including cameras, communication systems, and software, pose risks of data breaches and adversary control over drones.
• Intelligence agencies flagged Chinese components in domestically manufactured drones supplied to the Army, raising alarms about compromised intelligence-gathering and operational control.
