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. Manjit Singh.[1]


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.[2]

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.

Areas of work

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.[2]

Other Areas of work Include:[3]

  • Performance of armour defeating projectiles and immunity profiles
  • Studies of ground shock, blast damage, fragmentation and lethality
  • Preparation of safety templates for various weapons
  • Studies of underwater detonics and pressure wave propagation
  • Explosive forming, cladding and welding.
  • Detonation dynamics of high explosives.

Projects and Products

TBRL is responsible for the development of Explosive lenses for India's Nuclear weapons. These lenses were used on the Nuclear devices detonated in Pokhran-I and Pokhran-II.[4] Apart from this, TBRL also develops explosives-based products for conventional military and civilian use.[5]

Technologies for Civilian use

TBRL has developed a Non-lethal Riot control Plastic bullets for use by paramilitary forces and police, including usage for crowd control in Jammu and Kashmir manufactured by the Indian Ordnance Factories.[7][8]

    "The Bangalore range will be constructed by the Terminal Ballistic Research Laboratory, Chandigarh, a unit of the DRDO. The range will facilitate six firing positions and layers of wood-embedded walls will prevent bullets from going astray. Protecting walls will be built at every 20 feet of the firing range for a distance of 300 metres."
