Embraer's Netra Mk1A Upgrade: A Leap Forward in India's Airborne Surveillance Capabilities

The Indian Ministry of Defence is poised to finalize a deal with Brazilian aerospace major Embraer for the supply of six modified EMB-145 aircraft, which will serve as the backbone of the country's Airborne Early Warning and Control (AEW&C) programme. The programme, dubbed Netra Mk1A, represents a significant upgrade to the indigenously developed Netra Mk1 AEW&C system, which has already demonstrated its effectiveness in critical situations, including the 2019 Balakot airstrike and Operation Sindoor conducted on May 7, 2025.

The Netra Mk1A programme is a major leap forward in India's airborne surveillance capabilities, and a significant boost to the country's air defense posture. The programme's success hinges on Embraer's ability to source suitable used airframes from an increasingly thin global market of retired regional jets. With the EMB-145 production line long since discontinued, Embraer must scour the secondary market for suitable airframes, which will then be inspected, cleared, and modified at an Embraer facility before final sensor and radar integration takes place in Bengaluru.

This challenging task is not new to Embraer, as the company previously supplied three EMB-145s to India in the early 2010s for the original Netra programme, modifying them to integrate CABS' AESA radar, IFF systems, datalinks, and self-defence suites to IAF specifications. The Netra Mk1A represents a significant upgrade to the original Netra Mk1 system, with the addition of six new Mk1A aircraft set to significantly enhance the IAF's ability to detect low-flying objects, track enemy aircraft, drones, and cruise missiles, and manage complex operations.

The cornerstone of the Mk1A upgrade is the integration of Gallium Nitride (GaN) solid-state components into the aircraft's AESA radar, replacing the older Gallium Arsenide (GaAs) technology used in the original Netra Mk1 with modules offering superior power generation, better thermal management, and a longer operational lifespan. As a result, the upgraded radar system is projected to push its detection envelope to approximately 450 kilometres, a substantial improvement over the current Mk1 platforms.

Embraer will handle the sourcing, inspection, and initial structural modification of the airframes at its own facility, while DRDO's Centre for Airborne Systems in Bengaluru will manage the complex modification process, with technical collaboration from Embraer. CABS will handle the sensor and radar integration, with support from Indian private-sector partner Adani Defence and Aerospace. Once the modified airframes arrive in India, CABS will carry out the integration of the indigenous radar, electronic warfare suite, and other mission systems, followed by testing before final delivery to the IAF.

Reports suggest the contract could be concluded in the first half of next year, with platform delivery by late 2028. This tracks broadly with earlier industry estimates, and any shift in these dates would reflect the practical difficulty of sourcing suitable used airframes from an increasingly thin global market of retired regional jets.

Notably, Embraer has not stood entirely still on the airframe question. In June 2026, Embraer proposed its newer Praetor 600 business jet as an alternative structural platform for the Mk1A programme, a potentially significant pivot given the aircraft's range exceeding 7,400 kilometres, a service ceiling of 45,000 feet, and superior cruise speed and endurance compared to the ageing ERJ-145 design.

Whether the eventual deal sticks with used EMB-145 airframes or shifts towards the Praetor 600 alternative, remains an open question as negotiations proceed. One thing is certain, however - the Netra Mk1A's success will be a major leap forward in India's airborne surveillance capabilities, and a significant boost to the country's air defense posture.
