DRDO Insights
On January 1, 2026, the Defence Research and Development Organisation (DRDO) marked its 68th Foundation Day, celebrating nearly seven decades of innovation and commitment to India’s national security. Defence Minister Rajnath Singh acknowledged DRDO’s crucial role in bolstering indigenous defense capabilities and equipping the Armed Forces with state-of-the-art technologies, thereby driving India’s defense self-reliance and the ‘Atmanirbhar Bharat’ vision. This milestone followed “Operation Sindoor,” where DRDO-developed weapon systems played a decisive role, highlighting the organization’s professionalism and contribution to national interests.
DRDO, established in 1958 under the Ministry of Defence, originated from the amalgamation of the Technical Development Establishment (TDEs) of the Indian Army, the Directorate of Technical Development & Production (DTDP), and the Defence Science Organisation (DSO). It has grown into a network of over 50 laboratories across seven technology clusters, employing thousands of scientists and engineers in disciplines like aeronautics, armaments, electronics, combat vehicles, missiles, and naval systems.
DRDO’s core mission is to provide cutting-edge defense technologies for self-reliance through indigenous design, development, and production. Its mandate includes optimizing combat effectiveness, promoting troop well-being, and building a robust indigenous technology base with skilled manpower, reflecting strategic foresight and the pursuit of technological autonomy.
Operation Sindoor: A Defining Moment for DRDO Indigenous Defense Technology
“Operation Sindoor,” launched on May 7, 2025, was a decisive military action by the Indian Armed Forces against terrorist infrastructure in Pakistan, following a terrorist attack in Pahalgam on April 22, 2025, which killed 26 civilians. The operation, reportedly eliminating at least 100 terrorists, demonstrated India’s strategic resolve and indigenous technological strength. Defence Minister Rajnath Singh highlighted the seamless functionality of DRDO-developed weapon systems during the operation, boosting Armed Forces morale and proving DRDO’s professional excellence. DRDO Chairman Samir Kamat described the operation as a “declaration” of India’s self-reliance.
Key indigenous platforms and systems deployed in Operation Sindoor included:
- Akash Surface-to-Air Missiles: Medium-range air defense.
- BrahMos Supersonic Cruise Missile: Joint venture with Russia, a universal long-range missile.
- D4 Anti-Drone System: To counter UAV threats.
- Akashteer System: Advanced air defense control system integrating sensors and weapons.
- Sensors and Unmanned Systems: For intelligence, surveillance, and reconnaissance (ISR).
- Secure Communications: Indigenous systems for seamless coordination.
- AI-Based Decision Support Systems: For rapid decision-making.
- Precision Weapons: Including laser-guided bomb kits.
Operation Sindoor showcased India’s advanced capabilities in drone warfare, layered air defense, and electronic warfare, driven by DRDO’s sustained efforts.
Charting India’s Future: The Sudarshan Chakra Initiative and Next-Gen DRDO Technologies
DRDO is shaping India’s future defense landscape through long-term initiatives like the “Sudarshan Chakra initiative.”
Sudarshan Laser-Guided Bomb Kit: Precision in the Skies
This indigenous laser-guided bomb (LGB) kit, developed by DRDO’s Aeronautical Development Establishment (ADE) with support from Instruments Research and Development Establishment (IRDE), transforms conventional bombs into precision-guided munitions. Similar to GBU-16 Paveway II, it includes a computer control group (CCG), steerable canards, and a wing assembly. Following successful trials in 2010, the Indian Air Force (IAF) began upgrading its bomb inventory, enhancing precision strike capability and reducing reliance on foreign kits.
Mission Sudarshan Chakra: A Multi-Layered Air Defence Shield for India
This ambitious national security project, unveiled by Prime Minister Narendra Modi on Independence Day in 2025, aims to establish an indigenous, multi-layered, all-encompassing, and AI-enabled networked air defense architecture by 2035. It will provide complete aerial protection against threats like terrorist attacks, military strikes, ballistic missiles, hypersonic platforms, fighter aircraft, loitering munitions, and swarm drones, akin to Israel’s Iron Dome.
DRDO is the lead agency, responsible for developing and equipping vital installations. The system will integrate:
- Space-Based Tracking: Satellite networks for early detection.
- Automated Command and Control: AI-driven systems for threat assessment and response.
- Ground and Sea-Based Weapon Batteries: Including IADWS, QRSAM, and VSHORADS.
- Overlapping Network of Tracking and Early-Warning Sensors: Radars and sensors for comprehensive coverage.
- Directed Energy Weapons (DEW): High-energy lasers for neutralizing aerial threats.
The urgency of Mission Sudarshan Chakra is underscored by the experience of Operation Sindoor. DRDO is collaborating with the private sector and start-ups to expedite development.
