The Defence Research and Development Organisation (DRDO) is making significant strides with the Netra Mk-2 Airborne Early Warning and Control (AEW&C) initiative, marking a massive upgrade over its predecessor.
This ₹20,000 crore programme aims to replace the constraints of older systems with cutting-edge radar and sensor technology.
By stepping up to this next-generation platform, the Indian Air Force (IAF) is set to receive a substantial boost to its long-range scanning, target tracking, and overall combat-management strengths.
Reports indicate that the latest Mk-2 framework brings sweeping enhancements to the aircraft's radar design, tracking range, and sensor net.
These improvements are set to turn the aircraft into an elite aerial monitoring powerhouse, extending the defensive shield to detect threats from distances exceeding 500 kilometres.
At the heart of this upgrade is a highly advanced Active Electronically Scanned Array (AESA) radar, which traces its roots back to the indigenous Uttam radar project but has been specially modified for early warning duties.
Furthermore, this formidable radar setup is being built to fit onto modified Airbus A321 commercial jetliners, formerly operated by Air India, offering much greater endurance and flight ceiling than the smaller Embraer jets used in the past.
Choosing the larger Airbus A321 airframe provides engineers with the physical space needed to drastically scale up the radar systems and fuel capacity.
Consequently, the distinctive "balance beam" radar antenna mounted along the upper spine of the aircraft will be noticeably larger and more capable than the version seen on the older Netra Mk-1.
This beefed-up dorsal radar unit will pack nearly twice as many Transmit/Receive Modules (TRMs) as the previous iteration.
Crucially, these new modules will utilise advanced Gallium Nitride (GaN) technology, which runs cooler, requires less power, and emits stronger signals.
This massive increase in module count and efficiency sharpens the radar's clarity and range, empowering it to lock onto tiny, hard-to-spot threats like modern stealth fighter jets, cruise missiles, and unmanned drones.
A vital architectural shift in the Netra Mk-2 is the installation of a secondary AESA radar directly inside the nose of the plane.
Previous versions of the Netra depended heavily on the top-mounted radar, which unfortunately left a scanning blind spot directly in front of the aircraft.
By placing a dedicated radar in the nose, designers have successfully eliminated this flaw, granting the crew a clear view of what lies ahead.
In practical terms, the large top-mounted antenna delivers a sweeping 240-degree view covering both sides of the aircraft.
Meanwhile, the newly added nose radar adds a vital 60-degree sweep (±30 degrees) straight ahead.
Combined, this dual-sensor approach pushes the aircraft's total scanning field to roughly 300 degrees, reducing the unmonitored zone to just a narrow 60-degree sliver directly behind the tail.
Furthermore, the Netra Mk-2 relies on a cutting-edge 4D AESA multi-mode radar that operates on both S-band and X-band frequencies at the same time.
This versatile dual-band system allows the aircraft to execute a variety of complex roles simultaneously.
It can conduct extensive air-to-air scanning, track enemy naval vessels at sea, identify stealthy airborne threats, and keep a lock on fast, agile targets, including ballistic missiles.
All of this incoming data is then refined using advanced sensor fusion and instantly relayed to the IAF’s Integrated Air Command and Control System (IACCS) and friendly fighter squadrons.
With the first deliveries of the six planned aircraft anticipated around 2026 to 2027, the Netra Mk-2 is poised to become a vital force multiplier.
It will drastically elevate the Indian Air Force's capacity to spot stealth adversaries, manage multiple threats over massive areas, and direct complex aerial operations, guaranteeing absolute control of the skies during any future high-stakes conflicts.
