Full Form of DEW
What is DEW?
Distant Early Warning (DEW) refers to a network of radar systems designed to detect incoming aerial threats at long ranges, providing crucial advance notice for defensive responses. In the Indian context, DEW systems are operated by the Indian Air Force and the Integrated Air Command and Control System (IACCS) to monitor airspace along the country's borders, particularly in the northern and western sectors. These radars can identify hostile aircraft, cruise missiles, and drones many kilometers before they reach Indian territory, allowing fighter jets and air defense units to scramble. DEW technology is employed continuously at static radar stations and mobile units deployed during heightened tensions. The term originated from the Cold War-era DEW Line in North America, but in India it is used generically for long-range early warning radars. For defense aspirants, understanding DEW is essential for topics like air defense strategy, radar types, and IACCS integration, often appearing in written exams and interviews for the Indian Armed Forces and DRDO.
