DEAL was founded in 1965 in Mussoorie (Uttar Pradesh); it was then known as the Himalayan Radio Propagation Unit. In 1968, the lab was shifted from Mussoorie to Dehradun (Uttar Pradesh)* and in 1976 renamed as the Defence Electronics Applications Laboratory (DEAL). Since then, DEAL has expanded into a "major system laboratory" of the DRDO.

*Dehradun is now the capital of Uttaranchal, a new province that was carved out of Uttar Pradesh province in November 2000.

DEAL has developed:

  • "Jam-resistant data links for applications in real-time transmission of battlefield information for effective control of airborne platforms, target tracking and acquisition, and also in reconnaissance and surveillance using remotely piloted vehicles."
  • Microwave scanning antenna, which is part of the "terminal guidance system" used in ballistic missiles developed under the Integrated Guided Missile Development Program.
  • Command transmitter for the naval version of the Trishul short-range surface-to-air missile system.
