Defence Research and Development Laboratory


About Lab

To develop guided missile weapon systems in India, a Special Weapon Development Team (SWDT) was formed in 1958. This team was later expanded into a full-fledged laboratory in June 1961 at the campus of Defence Laboratory, Metcalfe House, Delhi. The laboratory moved to its present location at Kanchanbagh, Hyderabad, in 1962.

In the early years of its inception, DRDL was involved in the successful development of first generation Anti-Tank Guided Missiles, surface to air missiles ‘Devil’ and building up of infrastructure.

In order to equip India with state of the art missile technology and to ensure self reliance in defence systems, DRDO was entrusted with the task of developing various Missile systems through Integrated Guided Missile Development Programme (IGMDP) initiated in the year 1983. DRDL took a quantum jump through IGMDP by taking up design and development of various types of Missile Systems simultaneously and leading them to limited series / full scale production. After six years of commencement of IGMDP, the very first missile of PRITHVI (experimental flight) blasted off to a perfect flight from SHAR. There were a number of flight trials of PRITHVI, TRISHUL, AKASH, AGNI and NAG under IGMDP. The results of flight trials had their share of successes, failures and many areas of learning. Experience and knowledge gained in the fields of special technologies led to further development of Advanced Missiles Systems. To meet the growing demands of development, integration, testing and quality assurance, three establishments namely Research Centre Imarat (RCI), Composite Product Development Centre (CPDC), and Interim Test Range (ITR) came out under the parenthood of DRDL. A separate qualification agency Missile System Quality Assurance Agency (MSQAA) was established during this period. Later, these establishments acquired independent status. In the year 2000 another laboratory called Advanced Systems Laboratory (ASL) was carved out of DRDL to meet the specific requirements of long range systems.

Over the years, DRDL has grown in stature to become a multi-disciplinary Missile System Laboratory. The main thrust is on design, development and flight evaluation including weapon system command & control, and activities leading to production of various types of missile systems for our Armed Forces.

At present DRDL is involved in development of various missile systems like enhanced version of AKASH, ASTRA, LRSAM, HELINA, QRSAM, NGARM and MPATGM, SLCM, SMART, DHRUVASTRA, LRSAM-IAC; technologies like Liquid Fuel Ramjet, Solid Fuel Ducted Rocket Ramjet and Hypersonic Technology Demonstration Vehicle; infrastructure development like Hypersonic Wind Tunnel.

Today, DRDL along with other Missile Complex Laboratories viz. RCI, ASL, ITR and TBRL, form the cluster “Missiles & Strategic Systems”, which is the pioneer missile research cluster in the country.

Dr Dasharath Ram

Dr Dasharath Ram born on 1st February 1962, received his B.Tech in Electrical Engineering from Motilal Nehru Regional Engineering College, Allahabad University in 1984, M.Sc Engineering in Advanced Manufacturing Technology from Cranfield Institute of Technology, UK in 1992 and Ph.D in Production Engineering from Bharathiar University, Coimbatore in 2007.

He joined DRDL as Scientist-B in 1984 and presently he is Distinguised Scientist & Director, DRDL and Programme Director, PJ-10.

He headed number of Technology Directorates of DRDL to pursue the design and development of various missile projects. He has exposure in multi disciplinary areas and built-up state of art advanced manufacturing facility catering prototype hardware development of different missile projects at DRDL. He has significantly contributed in the areas of facility built-up, manufacturing technology development and its transfer to production agencies for productionisation.

He has been Project Director to establish a Hypersonic Wind Tunnel, 5th of its kind in the world to meet test requirements for design of futuristic Hypersonic Missiles and re-entry vehicles which requires generation of extensive aerodynamic data in hypersonic regime. He was involved in the design and development of the critical technologies such as Cored brick heaters, thermal insulator, modeling of heater and development and characterization of cored brick.

He has taken over as Programme Director of PJ-10, a joint venture BrahMos missile development between India and Russia. He has been responsible for the overall Weapon System Design and Development of the Complete Shore Based Complex, Inertial Guidance System, Missile Airframe Sections, Nose Cap, Canister, Telemetry and Transponder System for the Flight Testing, Productionisation of Missile Subsystems and Ground Complex, Development of Integration Infrastructure and Indigenization of Missile Sub-systems for Land/ship versions and air version.

He has published more than 40 papers in international journals and conferences. He has evaluated Ph.D thesis of Anna University, JNTU, Hyderabad, Osmania University, Hyderabad and NIT, Warangal.

He is recipient of Award for fabrication of Torque Shaft components of LCA Rudder Assembly, Swarna Jayanti Award – 1999 by Aeronautical Society of India, Eminent Mechanical Engineer Award – 2012 by Institution of Engineers (India) and I.T. Mirchandani Memorial Research Award-2013 by Indian Institute of Welding, India.

He is a fellow of Indian National Academy of Engineering, The Institution of Engineers (India), Aeronautical Society of India and Indian Institution of Production Engineers. He is a member of Indian National Society for Aerospace and related Mechanism, MINARM and Founder Life Member, Society for Failure Analysis, MSFA.
