Terminal Ballistics Research Laboratory (TBRL) is a laboratory of the Defence Research and Development Organisation (DRDO). Located in Chandigarh, the laboratory has become one of the major DRDO labs in the field of armament studies. TBRL is organized under the Armaments Directorate of DRDO. The present director of TBRL is Dr. Satish Kumar.
TBRL was envisaged in 1961 as a modern armament research laboratory under the Department of Defence Research & Development. It became fully operational in 1967 and was formally inaugurated in January 1968 by the then Defence Minister.
While the main laboratory is situated in Chandigarh, the firing range, spread over an area of 5,000-acre (20 km2), is located at Ramgarh in Haryana, 22 km away from Chandigarh.
TBRL conducts basic and applied research in the fields of high explosives, detonics and shock waves. It is also involved in evolving data and design parameters for new armaments, as well as assessing the terminal effects of ammunition.
