๐ก๏ธ Overview
The Defence Research & Development Organisation (DRDO) functions under the Department of Defence Research & Development (DDR&D), Ministry of Defence. It is the R&D wing of the Ministry, with a vision to empower India with cutting-edge defence technologies and a mission to achieve self-reliance in critical defence technologies and systems.
Motto: "เคฌเคฒเคธเฅเคฏ เคฎเฅเคฒเค เคตเคฟเคเฅเคเคพเคจเคฎเฅ" (Balasya Mulam Vigyanam) โ "The Source of Strength is Science."
- Vision: Empowering the nation with state-of-the-art indigenous Defence technologies and systems.
- Mission: Design, develop and lead to production state-of-the-art sensors, weapon systems, platforms and allied equipment for the Defence Services; provide technological solutions to optimise combat effectiveness and troop well-being; build a strong indigenous technology base.
๐ History & Formation
- DRDO was formed in 1958 by merging the Technical Development Establishment (TDE) of the Indian Army and the Directorate of Technical Development & Production (DTDP) of the Indian Ordnance Factories with the Defence Science Organisation (DSO), under Jawaharlal Nehru's administration.
- Started as a small organisation with 10 establishments/laboratories.
- A separate Department of Defence Research and Development was formed in 1980, which later administered DRDO.
- Defence Research & Development Service (DRDS) constituted in 1979 as a Group 'A' Officers service โ scientists directly under the Ministry of Defence.
- At its peak, DRDO had a network of ~52 laboratories โ now streamlined to ~41 + 5 DYSLs after rationalisation/mergers.
๐ฏ Key Historical Programmes
| Programme | Detail |
|---|
| Project Indigo (1960s) | DRDO's first major surface-to-air missile (SAM) project; discontinued without achieving full success. |
| Project Devil & Project Valiant (1970s) | Followed Project Indigo โ developed short-range SAM and ICBM technology. |

| Indigenous radar programme (from 1970s) | IAF's covert radar indigenisation effort, working with DRDO's LRDE lab, shaped the Indra and Rohini radar series. |
Rationalisation & Lab Mergers (Recent)
- Defence Terrain Research Laboratory (DTRL) merged with the Snow and Avalanche Studies Establishment (SASE), renamed as the Defence Geological Research Establishment (DGRE).
- As of 2020, ANURAG and LASTEC no longer function as independent entities โ staff relocated to DRDO labs in Hyderabad.
- The Defence Food Research Laboratory was merged with the Defence Research Development Establishment (DRDE), Gwalior.
- DRDO is planning a new research lab in Lucknow.
๐ค Leadership & Organisational Structure
- Secretary, DDR&D and Chairman DRDO (additional charge, June 2026): Shri Rajesh Kumar Singh, IAS โ took over from 31 May 2026, after Dr Samir V. Kamat's tenure (Aug 2022โMay 2026).
- Notable past Chairmen: Dr G. Satheesh Reddy (2018โ22, missile systems); Dr A.P.J. Abdul Kalam ("Father of India's military missile programme," led Project Devil, later 11th President); Dr Tessy Thomas ("Missile Woman of India," Agni programme).
- DRDO is organised into 7 Technology Clusters (domain-specific R&D, each headed by a Director General) and 5 Corporate Clusters (cross-cutting administrative/strategic functions).
Hierarchy: Raksha Mantri โ Secretary DDR&D & Chairman DRDO โ DRDO Management Council โ 7 Technology Clusters + 5 Corporate Clusters โ 41 Laboratories + 5 DYSLs.

๐ฐ๏ธ Remote Sensing & Satellite-Related Work at DRDO
DRDO is a defence R&D organisation, not a space agency like ISRO โ but several labs use remote sensing, GIS and satellite imagery for defence applications.
| Item | Detail |
|---|
| SASE / DGRE | Snow & avalanche remote sensing โ uses optical/microwave satellite imagery to identify avalanche-prone Himalayan regions; publishes the Avalanche Warning Bulletin. |

- Aims to transform DRDO into a leaner, DARPA-like institution โ R&D only, transferring prototype development/production to private industry & PSUs.
- Proposes a Department of Defence Science, Technology and Innovation (DDSTI) and a Defence Technology Council (DTC) headed by the PM.
- Recommends consolidating ~40 labs into ~10 national-level facilities plus 5 national test facilities open to private-sector use.
- Focus shift toward next-gen tech: directed energy weapons, photonics, quantum systems, AI. DRDO has reportedly agreed to implement ~60% of major recommendations.

๐ฏ Exam Angle
Prelims likes to test lab-location-function triads (DRDL/RCI/ASL โ Hyderabad โ missiles; NPOL โ Kochi โ naval physical/oceanographic; NSTL โ Visakhapatnam โ naval systems) and which cluster a given product belongs to. Mains rewards discussing DRDO 2.0's DARPA-like reform vision alongside India's broader defence self-reliance (Atmanirbhar Bharat) push โ the IGMDP-to-Agni-VI missile lineage is a strong illustrative example of indigenous capability building over four decades.
