India is aggressively scaling its airborne surveillance and command-and-control capabilities through a phased expansion of its indigenous Airborne Early Warning and Control (AEW&C) fleet. The initiative, overseen by the Ministry of Defence, aims to eliminate gaps in national airspace monitoring and establish a comprehensive “digital shield” capable of detecting and neutralizing airborne threats well before they reach their targets.
The strategy centers on a two-pronged approach: the rapid procurement of the Netra Mk-1A to provide immediate capacity, and the long-term development of the Netra Mk-2 to secure high-tier technological sovereignty.
The Expansion Plan
The immediate priority for the Ministry of Defence is the rollout of the Netra Mk-1A aircraft. Under current procurement projections, India intends to triple the size of its indigenous surveillance fleet by 2028. This expansion will see the total number of operational indigenous aircraft increase from six to eighteen.
The Netra system serves as a force multiplier for the Indian Air Force (IAF), acting as a flying radar station that can detect enemy aircraft, missiles, and drones at long ranges. By increasing the fleet to eighteen units, the IAF can maintain a more persistent presence in the sky, ensuring that multiple sectors of the border are monitored simultaneously without leaving critical windows of vulnerability.
Parallel to the Mk-1A rollout, the government has initiated the Netra Mk-2 program. This next-generation initiative is designed to deliver more advanced, fully indigenous AWACS (Airborne Warning and Control System) platforms by 2032. While the Mk-1A focuses on quantity and immediate coverage, the Mk-2 is intended to push the boundaries of detection range, resolution, and data processing, ensuring that India remains competitive against evolving stealth technologies and hypersonic threats.
Why It Matters
The ability to detect an incoming threat is the first and most critical step in any air defence architecture. Without airborne surveillance, ground-based radars are limited by the “curvature of the earth” and geographical obstructions like mountains, which create “blind spots” that enemy aircraft can exploit by flying at low altitudes.
AEW&C aircraft solve this problem by lifting the radar high into the atmosphere, providing a top-down view of the battlespace. This allows the IAF to:
1. Extend Detection Ranges: Identify threats hundreds of kilometers away, providing interceptor jets more time to scramble and engage.
2. Coordinate Interceptions: Act as a command-and-control hub, directing fighter aircraft to the exact coordinates of a target without the fighters having to reveal their own positions by turning on their own radars.
3. Monitor Low-Flying Threats: Detect cruise missiles and low-altitude strike aircraft that would otherwise be invisible to ground stations.
By tripling the fleet, India is moving from a “point-defence” posture—where specific high-value areas are protected—to a “blanket-coverage” posture, where the entire frontier can be monitored in real-time.
Background and Context
Historically, India has relied on a mix of indigenous efforts and foreign acquisitions to maintain its aerial surveillance. While the IAF operates a limited number of high-capability AWACS platforms, the reliance on foreign Original Equipment Manufacturers (OEMs) for spare parts and software updates has often created operational bottlenecks.
The Netra program represents a pivot toward “Atmanirbhar Bharat” (Self-Reliant India) in the defence sector. The development of the Netra series is a collaborative effort involving the Defence Research and Development Organisation (DRDO) and various domestic industry partners.
The transition from the early Netra models to the Mk-1A and eventually the Mk-2 reflects a learning curve in radar technology. Early iterations focused on basic detection; the current and future phases focus on “system-of-systems” integration, where the AEW&C aircraft can seamlessly share data with ground-based air defence systems, naval ships, and fighter jets in a unified network.
Analysis:
The strategic shift toward the Netra Mk-2 suggests that India is no longer content with “sufficient” surveillance but is seeking “dominant” surveillance. The move to a more advanced platform indicates an awareness of the proliferation of stealth aircraft and advanced electronic warfare (EW) suites in the region.
The decision to triple the fleet by 2028 is a calculated move to ensure overlapping coverage. In military terms, overlapping coverage means that if one aircraft must leave its station for refueling or maintenance, another is already in position to cover the sector. This eliminates the “blind spots” that are often the primary target of surprise aerial incursions. Furthermore, by investing in the Mk-2, India is attempting to decouple its national security from the supply chains of foreign powers, reducing the risk of sanctions or diplomatic pressure affecting its ability to maintain its “eyes in the sky.”
What to Watch Next
As the procurement of the Netra Mk-1A accelerates, several key indicators will determine the success of the program:
* Integration Timelines: Whether the eighteen aircraft can be integrated into the IAF’s command structure by the 2028 deadline without significant delays.
* Technological Leap in Mk-2: Whether the Mk-2 can successfully incorporate AESA (Active Electronically Scanned Array) radar technology and advanced signal processing to counter stealth threats.
* Industrial Scaling: The ability of domestic aerospace firms to scale production to meet the Ministry of Defence’s ambitious numbers.
* Network Centricity: The extent to which these platforms can integrate with the IAF’s newer fighter acquisitions, such as the Rafale and the upcoming Tejas Mk-2, to create a seamless kill-chain.
Conclusion
The expansion of the Netra fleet is more than a procurement exercise; it is a fundamental restructuring of India’s aerial early warning capabilities. By scaling the Mk-1A and developing the Mk-2, India is building a layered surveillance architecture designed to ensure that no airborne threat—be it a drone, a cruise missile, or a stealth fighter—can enter its airspace undetected. As the fleet grows toward 2028 and 2032, the IAF will transition from a reactive posture to a proactive one, securing the skies through indigenous intelligence and superior battlespace awareness.
