Defence Research and Development Organization (DRDO)

The Defence Research and Development Organisation (DRDO) is the premier research and development agency of the Ministry of Defence, Government of India. It was established in 1958 with the aim of developing indigenous defence technologies and systems to enhance India’s self-reliance in the defence sector.


The origins of DRDO can be traced back to the establishment of the Defence Science Organisation (DSO) in 1948. In 1958, the Defence Research and Development Organisation (DRDO) was formed by merging the Technical Development Establishment (TDEs) of the Indian Army and the Directorate of Technical Development and Production (DTDP) with the DSO.

Organisation Structure

DRDO is headed by the Secretary, Department of Defence Research and Development, who also serves as the Chairman of DRDO. The organisation has a network of over 50 laboratories and establishments spread across the country, each focused on specific areas of defence research and development.

Some of the key laboratories and establishments under DRDO include:

  • Aeronautical Development Agency (ADA)
  • Defence Research and Development Laboratory (DRDL)
  • Research Centre Imarat (RCI)
  • Defence Metallurgical Research Laboratory (DMRL)
  • Defence Food Research Laboratory (DFRL)
  • Defence Institute of Physiology and Allied Sciences (DIPAS)
  • Defence Institute of Psychological Research (DIPR)
  • Defence Terrain Research Laboratory (DTRL)
  • Defence Institute of High Altitude Research (DIHAR)
  • Centre for Artificial Intelligence and Robotics (CAIR)

Major Programmes and Achievements

DRDO has been involved in the development of a wide range of defence technologies and systems, including missiles, combat vehicles, aircraft, electronic warfare systems, radars, and naval systems. Some of the notable programmes and achievements of DRDO include:

  • Integrated Guided Missile Development Programme (IGMDP): This programme led to the development of a series of indigenous missiles, including Prithvi, Agni, Akash, Nag, and Trishul.
  • Light Combat Aircraft (LCA) Tejas: DRDO played a crucial role in the development of India’s first indigenous light combat aircraft, Tejas, which was inducted into the Indian Air Force in 2016.
  • Main Battle Tank (MBT) Arjun: DRDO developed India’s first indigenous main battle tank, Arjun, which has been inducted into the Indian Army.
  • Electronic Warfare Systems: DRDO has developed a range of electronic warfare systems, including Samyukta (mobile integrated electronic warfare system) and Sangraha (integrated electronic warfare system for Navy).
  • Radars: DRDO has developed various radar systems, such as the Rajendra radar for the Akash missile system and the Central Acquisition Radar for the Light Combat Aircraft.
  • Sonar Systems: DRDO has developed advanced sonar systems for the Indian Navy, including the USHUS submarine sonar and the HUMSA (Hull Mounted Sonar Array).
  • Anti-Tank Guided Missiles: DRDO has developed several anti-tank guided missiles, such as the Nag and the Helina (helicopter-launched Nag).

Collaboration and Partnerships

DRDO collaborates with various national and international institutions, universities, and industries for research and development activities. It has established joint ventures and partnerships with entities such as Bharat Electronics Limited (BEL), Hindustan Aeronautics Limited (HAL), and the Indian Institute of Technology (IIT) for the development of defence technologies.

Future Prospects

DRDO continues to focus on developing cutting-edge defence technologies to meet the evolving needs of the Indian armed forces. Some of the key areas of research and development include advanced materials, artificial intelligence, robotics, quantum technologies, and hypersonic vehicles.
