A separate Department of Defence Research and Development was formed in 1980 which later on administered DRDO and its 50 laboratories/establishments. The DRDO was established in 1958 by amalgamating the Defence Science Organisation and some of the technical development establishments. 4.1 Development cum Production Partner programme.4 Industry linkages, technology transfer and indigenisation.3.9.4 Long Range - Land Attack Cruise Missile (LR-LACM).3.8 Communication-Centric Intelligence Satellite (CCI-Sat).3.7.3 DRDO Smart Anti-Airfield Weapon (SAAW).3.6.12 Submarine-launched ballistic missile.3.6.11 Ballistic Missile Defence Programme.

2.1 Cluster Laboratories/Establishments.

The organisation includes around 5,000 scientists belonging to the DRDS and about 25,000 other subordinate scientific, technical and supporting personnel. With a network of 52 laboratories, which are engaged in developing defence technologies covering various fields, like aeronautics, armaments, electronics, land combat engineering, life sciences, materials, missiles, and naval systems, DRDO is India's largest and most diverse research organisation. Subsequently, Defence Research & Development Service (DRDS) was constituted in 1979 as a service of Group 'A' Officers / Scientists directly under the administrative control of Ministry of Defence. It was formed in 1958 by the merger of the Technical Development Establishment and the Directorate of Technical Development and Production of the Indian Ordnance Factories with the Defence Science Organisation. The Defence Research and Development Organisation ( DRDO) ( IAST: Raksā Anūsandhān Evam Vikās Sangaṭhan) ( Hindi: रक्षा अनुसंधान एवं विकास संगठन) is the premier agency under the Department of Defence Research and Development in Ministry of Defence of the Government of India, charged with the military's research and development, headquartered in Delhi, India.
