Defence Research and Development Laboratory (DRDL) is a Missile System laboratory - under the Defence Research and Development Organisation (DRDO) - with thrust on design, development and flight evaluation of various types of Missile Systems for the Indian armed forces. In 1958, the government of India constituted a team of Indian scientists - called the Special Weapons Development Team - to research guided missile weapons development. This team was later expanded into DRDL, a full-fledged laboratory, in June 1961, at the campus of Defence Science Centre, Delhi. It later shifted to Hyderabad after the state government granted them the former Nizam's army barracks. This was the genesis of the Defence Research and Development Laboratory (DRDL), under the Defence Research and Development Organisation.
