'''Defence Research and Development Laboratory''' ('''DRDL''') is an Indian missile development laboratory, part of the [[Defence Research and Development Organisation|Defence Research and Development Organization]] (DRDO). Their charter is centered on the design, development, and flight evaluation of various types of missile systems for the [[Indian armed forces]].

=== Vision and mission ===
Being a design and development house for missile-based weapon systems needed for tactical applications across multiple platforms is the organization's objective. Its aim is to create the cutting-edge technology and infrastructure needed for various class of missiles. Give the production agency the required technology for the guided missiles manufacturing.<ref name="drdl-vm">{{Cite web |title=DRDL - Homepage {{!}} Defence Research & Development Laboratory DRDO DRDO |url=http://drdo.gov.in/drdo/labs1/DRDL/English/indexnew.jsp?pg=homepage.jsp |archive-url=http://web.archive.org/web/20181111173658/https://drdo.gov.in/drdo/labs1/DRDL/English/indexnew.jsp?pg=homepage.jsp |archive-date=2018-11-11 |access-date=2025-04-29 |website=drdo.gov.in}}</ref>
▲In 1958, the government of India constituted a team of Indian engineers, mostly from the [[Indian Ordnance Factories]]- called the '''Special Weapons Development Team''' - to research guided missile weapons development. It was founded by [[S. P. Chakravarti]], the father of Electronics and Telecommunication engineering in India, who also founded the DLRL and the [[Electronics and Radar Development Establishment]] (LRDE).<ref>{{cite journal |url=https://in.booksc.eu/book/53133498/850b31 |title=Prof. S.P.

The DRDO launched [[Project Devil]] and [[Project Valiant]] to reverse engineer Soviet-origin guided missiles and create intercontinental ballistic missiles, respectively, which prompted the DRDL to begin developing missile guidance systems. Although both initiatives were abandoned before they were successful, the work completed aided DRDL in increasing its capacity. Afterwards, this assisted DRDL in leading the [[Integrated Guided Missile Development Programme|Integrated Guided Missiles Development Program]] (IGMDP). By 2011, India started producing cutting-edge components in-house and was fully independent in end-to-end missile development.<ref name=":0" />
