From Balakot to Operation Sindoor: Why DRDO's Netra AEW&C Is One of India's Most Important Defence Assets
India has achieved another major milestone in defence self-reliance with the Defence Research and Development Organisation (DRDO) officially handing over the Final Operational Clearance (FOC) of the indigenous Netra Airborne Early Warning and Control (AEW&C) system to the Indian Air Force (IAF).
The clearance marks the successful completion of years of testing, operational validation, and system improvements, bringing one of India's most sophisticated airborne surveillance platforms into its final operational configuration.
Often described as India's indigenous "Eye in the Sky," Netra is designed to detect hostile aircraft, incoming missiles, ships, drones, and electronic emissions long before they become a threat. By providing real-time intelligence and battlefield awareness, the system enables military commanders to make faster and more informed operational decisions during both peacetime surveillance and wartime missions.
The achievement also represents another significant step towards the Government's Aatmanirbhar Bharat vision by reducing dependence on imported airborne surveillance systems while strengthening India's indigenous aerospace and defence manufacturing capabilities.
What Is Netra AEW&C? Understanding India's Indigenous Airborne Early Warning and Control System
DRDO's Advanced Airborne Radar and Command Centre Designed to Detect Threats Hundreds of Kilometres Away
The Airborne Early Warning and Control (AEW&C) system is a sophisticated military surveillance platform that combines advanced radar, communication systems, electronic intelligence sensors, and airborne command-and-control capabilities on board an aircraft.
Unlike conventional ground-based radar systems, airborne early warning aircraft operate at high altitudes, allowing them to detect aerial and maritime threats over a much larger area while overcoming limitations caused by the Earth's curvature and mountainous terrain.
According to DRDO, the AEW&C system consists of advanced sensors mounted on an aircraft that perform multiple critical functions simultaneously, including:
Detecting hostile aircraft.
Tracking incoming missiles.
Monitoring sea surface targets.
Identifying hostile electronic emissions.
Providing early warning to military commanders.
Supporting interception missions.
Sharing real-time battlefield intelligence with ground stations and combat aircraft.
By continuously monitoring India's airspace and surrounding regions, Netra functions as an airborne command centre capable of coordinating multiple air defence assets simultaneously.
Why Is Netra Called India's 'Eye in the Sky'?
The Airborne Surveillance Platform Gives the Indian Air Force Real-Time Situational Awareness
Modern aerial warfare increasingly depends on information superiority.
Rather than waiting for hostile aircraft or missiles to approach national airspace, militaries now rely on airborne surveillance systems capable of detecting threats hundreds of kilometres before they reach friendly territory.
This is precisely the role performed by Netra AEW&C.
Operating high above the battlefield, the system continuously scans vast areas using advanced radar while simultaneously tracking multiple airborne and maritime targets.
It provides:
Real-time air picture.
Enemy aircraft tracking.
Missile detection.
Maritime surveillance.
Electronic intelligence.
Airspace management.
Command and control support.
The information collected is instantly transmitted to:
Indian Air Force command centres.
Ground-based air defence systems.
Fighter aircraft.
Military commanders overseeing operations.
This integrated situational awareness allows India to react far earlier than would otherwise be possible.
Netra AEW&C Receives Final Operational Clearance After Nearly Eight Years
FOC Marks Completion of Extensive Operational Testing Since Initial Clearance in 2017
The latest milestone is particularly significant because the Netra programme has been under development for nearly two decades.
The system received its:
Initial Operational Clearance (IOC)
in October 2017.
Initial Operational Clearance allowed the Indian Air Force to begin operational deployment while DRDO continued testing, software upgrades, hardware refinements, and mission validation under actual operational conditions.
After years of extensive evaluation and improvements, DRDO has now formally handed over the:
Final Operational Clearance (FOC)
to the Indian Air Force.
The FOC confirms that Netra has successfully completed:
Flight testing.
Performance validation.
Operational evaluations.
Reliability assessments.
Software upgrades.
Hardware improvements.
Mission capability verification.
Safety certification.
It also signifies that the aircraft has reached its final approved operational standard for long-term military deployment.
Netra Uses India's Indigenous AESA Radar Technology
Advanced Electronically Scanned Radar Provides High-Speed Detection of Multiple Threats
One of Netra's most advanced features is its:
Active Electronically Scanned Array (AESA) Radar
developed indigenously by DRDO.
Unlike mechanically rotating radar systems, AESA radar electronically steers radar beams without physically moving the antenna.
This provides several advantages:
Faster target detection.
Higher tracking accuracy.
Improved reliability.
Simultaneous tracking of multiple targets.
Better resistance to electronic jamming.
Reduced maintenance requirements.
The radar is housed within an:
Active Antenna Array Unit (AAAU)
mounted on top of the aircraft.

Netra Can Detect Low-Flying Aircraft and Missiles Long Before They Become Visible to Ground Radar
The indigenous AESA radar provides approximately:
240-Degree Radar Coverage
while mounted on two modified:
Embraer EMB-145 Regional Jets
The radar is capable of detecting:
Low-flying fighter aircraft.
Cruise missiles.
Drones.
Helicopters.
Maritime targets.
Hostile aircraft formations.
According to available information, Netra can detect low-flying aerial threats at distances of approximately:
375 Kilometres
This capability significantly enhances India's early warning network by providing advance notice of incoming threats before they approach defended airspace.
How Does Netra Compare With India's Phalcon AWACS?
Netra Complements the Israeli-Origin Airborne Warning Fleet Operated by the Indian Air Force
While Netra represents India's indigenous airborne surveillance capability, the Indian Air Force also operates:
Three Phalcon Airborne Warning and Control Systems (AWACS)
These aircraft combine:
Israeli EL/W-2090 radar.
Russian Ilyushin Il-76 heavy transport aircraft.
Compared with Netra, the Phalcon system offers:
Approximately 360-degree radar coverage.
Detection range of around 500 kilometres.
Netra, on the other hand, provides:
Indigenous technology.
Lower operational costs.
Greater domestic control over upgrades.
Enhanced self-reliance.
Reduced dependence on imported systems.
Rather than replacing the Phalcon fleet, Netra complements India's overall airborne surveillance architecture.
A Major Step Towards Aatmanirbhar Bharat in Defence Technology
Indigenous Development Reduces Dependence on Foreign Military Platforms
The successful completion of Netra AEW&C reflects India's growing capability to design and manufacture highly sophisticated defence technologies domestically.
Developing an airborne early warning platform involves expertise in:
Radar engineering.
Signal processing.
Aerospace integration.
Electronic warfare.
Mission computers.
Secure communications.
Sensor fusion.
Command-and-control software.
The Final Operational Clearance demonstrates that Indian defence scientists have successfully integrated these complex technologies into an operational military platform.
The achievement also strengthens India's long-term objective of building a self-reliant defence industrial ecosystem capable of producing advanced surveillance and command systems for future military requirements.
Why Netra AEW&C Is Becoming a Game-Changer for India's Air Defence
With the award of Final Operational Clearance, Netra has moved beyond developmental status to become a fully operational component of India's air defence network.
Its advanced radar, indigenous technology, real-time surveillance capability, and battlefield command functions make it one of the most important force multipliers available to the Indian Air Force.
However, Netra's true operational value became evident during two of India's most significant military operations—the 2019 Balakot air strike and Operation Sindoor—where it quietly played a decisive role behind the scenes.
How Netra AEW&C Helped India During Balakot Air Strike and Operation Sindoor | The Silent Guardian Behind India's Precision Air Operations
From Monitoring Enemy Aircraft to Providing Real-Time Airspace Awareness, Netra Played a Crucial Role in Two of India's Most Important Military Missions
While fighter aircraft and precision-guided weapons often receive the most attention during military operations, modern air warfare depends equally on airborne surveillance and command systems operating far behind the frontlines.
The indigenous Netra Airborne Early Warning and Control (AEW&C) system has quietly emerged as one of the Indian Air Force's most valuable force multipliers, providing commanders with real-time intelligence, surveillance, target tracking, and battlefield awareness.
During the ceremony marking the Final Operational Clearance (FOC) of Netra AEW&C, the Deputy Chief of the Air Staff confirmed that the indigenous platform had been successfully employed during both:
Operation Sindoor, and
The 2019 Balakot Air Strike
The confirmation publicly established what defence experts had long believed—that Netra had become an integral component of India's modern air warfare doctrine.
Operation Balakot: Why India Launched the Air Strike
The Indian Air Force Carried Out a Precision Strike Following the Pulwama Terror Attack
On 14 February 2019, a suicide terrorist attack in Pulwama, Jammu and Kashmir, claimed the lives of 40 Central Reserve Police Force (CRPF) personnel.
In response, India decided to conduct a carefully planned cross-border air operation targeting a major Jaish-e-Mohammed (JeM) terrorist training facility located at Balakot in Pakistan.
The operation, conducted on 26 February 2019, was code-named:
Operation Bandar
It marked one of the most significant air operations undertaken by India in decades.
Unlike previous responses confined largely to ground operations or artillery exchanges, the Balakot strike demonstrated India's willingness to employ air power against terrorist infrastructure located deep inside Pakistani territory.
How the Indian Air Force Executed the Balakot Air Strike
Mirage-2000 Fighter Jets Led the Precision Attack Before Dawn
The mission was executed during the early hours of 26 February 2019, when the Indian Air Force deployed its battle-proven Mirage-2000 fighter aircraft.
Originally manufactured in France, the Mirage-2000 fleet had already established its combat credentials during the 1999 Kargil War.
For the Balakot mission, the aircraft were equipped with advanced avionics, including:
Night-vision capable glass cockpits.
Upgraded navigation systems.
Modern Identification Friend or Foe (IFF) technology.
Advanced multi-mode radar.
Integrated electronic warfare systems.
These capabilities enabled the aircraft to undertake a complex precision strike under darkness while minimising the chances of detection.
Mirage-2000 Jets Were Escorted by Sukhoi Su-30 Fighters
Air Superiority Was Maintained Throughout the Operation
Approximately twelve Mirage-2000 fighter aircraft participated in the strike mission.
They were escorted by four Sukhoi Su-30 fighters, which performed an air defence role during the operation.
The Sukhoi aircraft were tasked with:
Protecting the strike package.
Responding to possible Pakistani Air Force intervention.
Maintaining aerial superiority during the mission.
According to available information, no direct aerial engagement with Pakistani fighter aircraft occurred during the strike.
How India Avoided Pakistani Radar Detection
Low-Level Flying, Terrain Masking and Decoy Aircraft Helped Maintain Surprise
One of the most remarkable aspects of Operation Balakot was the Indian Air Force's ability to approach the target without triggering an effective Pakistani response.
According to defence sources, multiple tactics were employed simultaneously.
These included:
Terrain Masking
The strike aircraft used surrounding hills and mountainous terrain to remain concealed from enemy radar for much of their flight.
Low-Level Flight
The Mirage-2000 fighters flew at extremely low altitude before climbing sharply shortly before weapon release.
Decoy Aircraft
The Indian Air Force also reportedly employed two decoy formations designed to distract Pakistani air defence systems and create uncertainty regarding the actual direction of attack.
The combination of these tactics significantly reduced Pakistan's ability to detect and intercept the strike package.
Precision Weapons Used During Operation Balakot
SPICE-2000 and Crystal Maze Missiles Delivered High-Accuracy Strikes
The Mirage-2000 aircraft carried sophisticated precision-guided weapons capable of striking targets from safe stand-off distances.
Among the principal weapons employed were:
SPICE-2000
and
Crystal Maze Mark-II (AGM-142 Popeye)
Both weapons are designed for high-precision attacks against fortified targets.
What Is SPICE-2000?
Smart Guidance Kit Converts Conventional Bombs into Precision Weapons
SPICE stands for:
Smart, Precise Impact and Cost-Effective
Rather than being an entirely new missile, SPICE-2000 is an advanced guidance kit developed in Israel.
The system converts standard:
2,000-pound Mk-84 unguided bombs
into precision-guided munitions capable of striking designated targets with exceptional accuracy.
Using satellite navigation, electro-optical guidance, and advanced target-recognition capabilities, SPICE-2000 significantly improves strike precision while reducing collateral damage.
What Is the Crystal Maze (AGM-142 Popeye) Missile?
Stand-Off Missile Allows Aircraft to Strike Without Flying Directly Over the Target
Another key weapon available to the Mirage-2000 fleet is the:
Crystal Maze Mark-II
also known as:
AGM-142 Popeye
Developed in Israel, the missile is designed for stand-off attacks.
Its approximate operational range of:
90 Kilometres
allows aircraft to launch the weapon from a considerable distance without flying directly over heavily defended targets.
This capability substantially enhances aircraft survivability during high-risk strike missions.
Netra and Phalcon Worked Together During the Balakot Operation
India's Airborne Surveillance Aircraft Ensured the Airspace Remained Clear
While Mirage-2000 fighters conducted the strike, airborne surveillance platforms continuously monitored the surrounding airspace.
The Indian Air Force deployed:
Israeli Phalcon Airborne Warning and Control System (AWACS), and
Indigenous Netra Airborne Early Warning and Control (AEW&C)
throughout the mission.
According to official information, these airborne platforms confirmed that:
No Enemy Aircraft Came Within Approximately 100 Kilometres of the Strike Package During the Operation
This continuous surveillance enabled commanders to maintain real-time situational awareness and ensured that the mission proceeded without unexpected aerial interference.
Netra AEW&C Also Played an Important Role During Operation Sindoor
Deputy Chief of Air Staff Confirms Operational Deployment
During the Final Operational Clearance ceremony, the Deputy Chief of the Air Staff publicly confirmed that Netra AEW&C was also operationally deployed during:
Operation Sindoor
Although detailed operational information remains classified, the confirmation demonstrates that Netra has become a trusted component of India's operational air defence architecture.
Its deployment during two major military operations highlights the confidence placed in the indigenous system by the Indian Air Force.
Why Airborne Early Warning Systems Are Critical in Modern Air Warfare
Modern combat aircraft may deliver weapons, but success increasingly depends upon information dominance.
Airborne Early Warning and Control systems such as Netra perform functions that fighter aircraft alone cannot accomplish.
These include:
Detecting enemy aircraft hundreds of kilometres away.
Monitoring multiple aerial threats simultaneously.
Tracking hostile missiles.
Coordinating friendly aircraft.
Managing complex airspace.
Providing real-time intelligence to commanders.
Supporting interception operations.
Integrating airborne and ground-based surveillance.
Without platforms like Netra, modern precision strike missions become significantly more difficult to execute safely and effectively.
From Airborne Surveillance to Integrated Battlefield Management
Netra's successful deployment during both Operation Balakot and Operation Sindoor demonstrates that India's indigenous airborne surveillance capability has matured into a reliable operational asset.
However, airborne surveillance represents only one component of India's increasingly sophisticated air defence network.
Behind every radar contact, fighter aircraft, missile battery, and airborne warning platform lies an integrated digital command system that combines information from every sensor into a single operational picture.
Integrated Air Command and Control System (IACCS): The Digital Brain Behind India's Air Defence Network | How Netra, Phalcon, Fighter Jets and Radars Work Together
From Netra AEW&C to Akashteer: How India Is Building a Fully Network-Centric Air Defence System for Modern Warfare
While Netra AEW&C provides the Indian Air Force with airborne surveillance and early warning capabilities, the true strength of India's air defence lies in its ability to connect every radar, sensor, missile battery, command centre, and fighter aircraft into a single, integrated network.
This role is performed by the Integrated Air Command and Control System (IACCS)—an advanced digital command-and-control network that serves as the backbone of India's air defence architecture.

During Operation Sindoor, the IACCS played a decisive role by integrating airborne surveillance systems such as Netra and Phalcon with ground-based radars, communication networks, and operational command centres, enabling military commanders to respond rapidly to evolving aerial threats.
The system has transformed the Indian Air Force from operating individual platforms into a fully network-centric fighting force, where every sensor and every weapon contributes to one common operational picture.
What Is the Integrated Air Command and Control System (IACCS)?
India's Fully Automated Air Defence Network That Connects Every Sensor, Radar and Fighter Aircraft
The Integrated Air Command and Control System (IACCS) is an automated command-and-control network developed to integrate all air defence assets operated by the Indian Air Force.
The system has been developed by Bharat Electronics Limited (BEL), one of India's leading public sector aerospace and defence electronics companies.
Rather than functioning as a single radar or command centre, IACCS acts as a nationwide digital network that continuously gathers, processes, and distributes information received from multiple defence assets.
Its primary objective is to provide commanders with a single, real-time operational picture of India's airspace.
How Does IACCS Work?
The System Combines Data From Multiple Military and Civilian Sources Into One Unified Operational Picture
One of the biggest challenges during modern air operations is handling enormous volumes of information arriving simultaneously from different surveillance platforms.
IACCS addresses this challenge by integrating data from numerous sources, including:
Ground-based military radar.
Airborne Early Warning and Control (AEW&C) aircraft.
Phalcon AWACS.
Civilian radar networks.
Communication nodes.
Air defence command centres.
Fighter aircraft.
Missile defence units.
Other surveillance assets.
Instead of commanders receiving fragmented information from separate systems, IACCS merges all available data into one consolidated operational display.
This significantly improves both situational awareness and decision-making during military operations.
Why Real-Time Situational Awareness Is Critical in Modern Air Warfare
Military Commanders Need Immediate Information to Counter Fast-Moving Threats
Modern aerial threats—including fighter aircraft, cruise missiles, drones, helicopters, and ballistic missiles—can appear with little warning and travel at extremely high speeds.
In such scenarios, delays of even a few seconds can have significant operational consequences.
By continuously updating information from multiple surveillance systems, IACCS enables commanders to:
Detect hostile aircraft early.
Track multiple threats simultaneously.
Monitor friendly aircraft movements.
Identify potential interception opportunities.
Coordinate fighter responses.
Allocate missile defence assets.
Maintain comprehensive airspace awareness.
This integrated picture allows commanders at different levels to make faster and more informed operational decisions.
How IACCS Supported Operation Sindoor
Net-Centric Warfare Enabled Better Coordination During India's Air Operations
During Operation Sindoor, the Indian Air Force brought together multiple surveillance and combat assets through the IACCS network.
The system integrated information from:
Netra AEW&C.
Phalcon AWACS.
Ground radar stations.
Communication networks.
Air defence command centres.
The availability of a continuously updated operational picture allowed commanders to coordinate air operations more efficiently while maintaining awareness of potential aerial threats.
According to available information, this net-centric operational capability proved vital for conducting modern military operations requiring rapid coordination among multiple platforms.
Why Radar Integration Makes India's Air Defence More Effective
Overlapping Radar Coverage Reduces Blind Spots Across Indian Airspace
A major advantage of IACCS is its ability to combine overlapping radar coverage from different surveillance systems.
Rather than relying on a single radar installation, information from multiple sources is fused together.
This approach offers several operational advantages:
Reduced blind spots.
Better target tracking.
Greater reliability.
Continuous monitoring.
Improved airspace management.
Reduced duplication of surveillance efforts.
Even if one radar temporarily loses contact with a target, another sensor within the network can continue tracking it, ensuring uninterrupted situational awareness.
Netra AEW&C and IACCS: A Powerful Combination
Airborne Surveillance Becomes More Effective When Connected to a Nationwide Defence Network
Netra AEW&C is extremely capable on its own.
However, its effectiveness increases significantly when connected to IACCS.
Once Netra detects:
Enemy aircraft.
Missiles.
Drones.
Maritime targets.
Electronic emissions.
the information is transmitted almost instantly to the wider IACCS network.
This allows:
Air defence commanders.
Fighter squadrons.
Missile batteries.
Ground-based radar operators.
Command headquarters.
to receive the same operational information simultaneously.
Such real-time information sharing is one of the defining characteristics of modern network-centric warfare.
What Is Akashteer? India's Army Air Defence Network Explained
Indian Army Operates a Similar Digital Air Defence System
While the Indian Air Force relies on IACCS, the Indian Army operates a comparable air defence command-and-control network known as:
Akashteer
Akashteer connects the Army's various air defence units into a unified reporting and command system.
Its primary functions include:
Air defence coordination.
Target reporting.
Threat identification.
Missile deployment support.
Communication between Army air defence units.
Although operated separately, both IACCS and Akashteer represent India's broader transition toward digitally integrated military operations.
Why Airborne Early Warning Systems Have Become Essential in Modern Warfare
Countries Cannot Rely Solely on Ground Radar for National Air Defence
Modern military aircraft increasingly operate with:
Stealth technology.
Electronic warfare capabilities.
Long-range precision weapons.
Stand-off missiles.
Swarm drones.
As a result, airborne surveillance platforms such as Netra AEW&C have become indispensable.
Compared with traditional ground radar, airborne early warning systems offer:
Greater surveillance range.
Earlier threat detection.
Better low-altitude coverage.
Wider battlefield visibility.
Faster operational response.
They also serve as airborne command centres capable of directing fighter aircraft during complex combat operations.
What Netra AEW&C Means for India's Defence Modernisation
