New Delhi: Arudhra Radar has come into the spotlight after an AI-assisted simulation reportedly demonstrated the indigenous radar’s ability to detect and track a simulated Lockheed Martin F-35A stealth fighter within India’s integrated air defence network.
While the exercise was a computer-based simulation and not a real-world interception, it highlights the growing capabilities of India’s indigenous radar ecosystem and the increasing role of artificial intelligence in modern air warfare.
Details of Arudhra Radar
A recent AI-assisted simulation showcased how the DRDO-developed Arudhra Medium Power Radar (MPR) could identify, monitor and relay tracking information of a simulated F-35A stealth aircraft within the Indian Air Force’s network-centric air defence architecture.
According to available information:
- The exercise was conducted in a virtual environment.
- The radar continuously tracked a simulated low-observable target.
- Data was transmitted to the Indian Air Force’s Integrated Air Command and Control System (IACCS).
- AI models were used to assess tracking quality and engagement options.
- The exercise aimed to evaluate India’s capability against advanced stealth threats.
What is Arudhra Radar?
Arudhra is an indigenous 4D Active Electronically Scanned Array (AESA) Medium Power Radar developed by DRDO and manufactured by Bharat Electronics Limited (BEL). It is designed for:
- Air surveillance
- Target detection
- Aircraft tracking
- Missile tracking
- Air defence coordination
What are the Features of Arudhra Radar
- Electronic beam steering
- 360-degree coverage
- Multi-target tracking capability
- Resistance to electronic warfare measures
- Integration with India’s air defence network
The radar is expected to replace several ageing surveillance systems currently used by the Indian Air Force.
Why Tracking an F-35A Matters
The F-35A Lightning II is among the world’s most advanced fifth-generation stealth fighters.
Its major advantages include:
- Reduced radar cross-section
- Advanced electronic warfare systems
- Sensor fusion capabilities
- Network-centric warfare features
Stealth aircraft are designed to reduce detection by conventional radars. Therefore, any radar demonstrating the ability to track such aircraft—even in simulation—attracts significant attention in defence circles.
What is the Role of IACCS in the Arudhra Radar
The Indian Air Force’s Integrated Air Command and Control System (IACCS) acts as the digital backbone of India’s air defence network.
The system:
- Integrates radar feeds nationwide.
- Combines military and civilian sensor data.
- Provides a real-time air picture.
- Supports rapid threat assessment.
- Enables coordinated responses across different commands.
In the simulation, Arudhra reportedly fed tracking data into this network, demonstrating how indigenous sensors can contribute to a unified air defence environment.
Why This Development Is Important
1. Strengthening Indigenous Defence Technology
India has increasingly focused on reducing dependence on foreign military systems.
Arudhra represents:
- Indigenous radar design.
- Local manufacturing.
- Domestic software integration.
- Reduced import dependency.
This aligns with the government’s broader Atmanirbhar Bharat defence strategy.
2. Growing Focus on Counter-Stealth Warfare
Future air combat will increasingly involve stealth aircraft such as:
- F-35A
- J-20
- Su-57
- J-35
To counter these threats, India is investing in:
- AESA radars
- Passive radar networks
- Long-range surveillance systems
- AI-powered threat analysis
The Arudhra simulation fits into this larger modernization effort.
3. AI Becoming a Force Multiplier
Artificial Intelligence is transforming military operations.
Potential benefits include:
- Faster target identification
- Better threat classification
- Reduced operator workload
- Improved engagement decisions
- Enhanced battlefield awareness
The simulation demonstrates how AI could support future air defence operations rather than relying solely on human operators.
Important Caveat: Simulation Is Not Real-World Proof
Defence experts note that computer simulations are valuable for testing concepts but cannot fully replicate real combat conditions.
Factors that affect actual radar performance include:
- Weather conditions
- Electronic jamming
- Terrain masking
- Flight profiles
- Pilot tactics
- Electromagnetic interference
Therefore, the exercise should be viewed as a technology demonstration rather than confirmation that Arudhra can consistently track operational F-35 aircraft in real-world combat scenarios.
What Comes Next?
India is expected to continue expanding its indigenous radar network through:
- Arudhra MPR deployment
- Ashwini Low-Level Transportable Radar induction
- Long-range surveillance radar projects
- AI-enabled command systems
- Integrated air defence modernization programs
These developments are aimed at improving India’s ability to detect and respond to emerging aerial threats across multiple domains.
