DRDO, HAL & Defence Orgs

Defence GK · DRDO, HAL और रक्षा संगठन

📋Quick Overview

India has a robust defence industrial base led by DRDO, HAL, BEL, BEML, and other Defence Public Sector Undertakings (DPSUs). The Ordnance Factories Board was dissolved in 2021 and its units reorganised into 7 DPSUs. India aims for self-reliance in defence through the 'Atmanirbhar Bharat' policy, iDEX startup ecosystem, and the Defence Acquisition Procedure (DAP 2020).

DRDO was established on January 1, 1958. It has 50+ laboratories and employs about 30,000 scientists. HAL (Hindustan Aeronautics Ltd) was established in 1940 in Bangalore — it is Asia's oldest and largest aerospace company.
