DRDO

What is DRDO?

The Defence Research and Development Organisation (DRDO) is India's premier agency for military research and development, working under the Ministry of Defence. Established in 1958 by merging the Technical Development Establishment and the Directorate of Technical Development and Production, DRDO has grown into a network of over 50 laboratories and establishments across India, staffed by approximately 5,000 scientists and 25,000 support personnel.

DRDO's mandate is to design, develop, and lead to the production of state-of-the-art weapon systems, platforms, and strategic technologies for India's armed forces. Its portfolio spans missile systems, combat aircraft, armoured vehicles, naval systems, electronic warfare, cyber systems, life sciences, and materials technology. The organisation is headed by the Secretary, Department of Defence R&D, who also serves as Scientific Adviser to the Defence Minister.

Under the DRDO 2.0 strategy (announced 2025), the organisation is pivoting from conventional weapons development to next-generation technologies — directed energy weapons, photonics, quantum systems, hypersonics, and AI — while transferring conventional system development and manufacturing to the private sector.

Major Cluster Labs

DRDO's 50+ labs are grouped into technology clusters: Missiles and Strategic Systems (DRDL Hyderabad, RCI), Aeronautics (ADA, ADE Bangalore), Naval Systems (NSTL Visakhapatnam), Armaments (ARDE Pune), Electronics and Communication (LRDE Bangalore, DEAL Dehradun), Life Sciences (DIPAS Delhi, DFRL Mysore), Combat Vehicles (CVRDE Chennai), Materials (DMRL Hyderabad), and Nuclear and Advanced Technologies. Key testing facilities include the Integrated Test Range (ITR) at Chandipur (Odisha) for missile testing and the Terminal Ballistics Research Laboratory (TBRL) at Chandigarh.
