India Reveals Next-Gen NETRA AEW&C Mk2: Enhanced with DRDO’s Uttam Radar and Modified Airbus A321

India’s journey to modernize its airborne defence capabilities took a giant leap forward with the recent unveiling of the DRDO-Airbus NETRA AEW&C (Airborne Early Warning and Control) Mk2 model. Displayed during the inauguration of the new C295 aircraft final assembly line in Vadodara, the model represents India’s commitment to enhancing its surveillance and command infrastructure with state-of-the-art technology and international partnerships. 

The NETRA AEW&C Mk2 is no ordinary surveillance aircraft. It combines the latest in radar technology and airborne warning systems, purpose-built for the Indian Air Force (IAF). Designed as an upgrade over India’s existing NETRA Mk1 systems, the Mk2 model brings an impressive set of enhancements, beginning with its core radar: DRDO’s indigenous Uttam Active Electronically Scanned Array (AESA) radar. 

The Power of the Uttam Radar

A standout feature of the NETRA AEW&C Mk2 is its incorporation of the Uttam AESA radar. Originally developed for the Tejas Light Combat Aircraft, the Uttam radar’s multi-target tracking capability is key to the Mk2's enhanced situational awareness. Known for its capacity to monitor and lock onto multiple targets at once, the radar can detect both airborne and maritime threats with high precision. This versatility significantly boosts the IAF’s defensive and offensive reach, offering a broader and more detailed scope of enemy activities across the operational theater.

The Uttam radar is also versatile across weather conditions and can differentiate between friend and foe, a crucial advantage in modern warfare. With its electronically scanned array, the radar offers a broader field of vision compared to traditional mechanically scanned radars, helping Indian forces detect threats early and with minimal delay.

Airbus A321: A Sturdy Platform for an Advanced System

The A321 aircraft itself, modified extensively to house this advanced AEW&C system, has been customized to carry the NETRA’s radar and support equipment while maintaining excellent performance and range. Airbus is conducting these structural modifications in its Spain facilities, where the aircraft is being equipped with essential subsystems to prepare it for AEW&C operations. Once these modifications are complete, the aircraft will return to India, where DRDO will perform the final integration of the Uttam radar and other indigenous components.

These customizations enable the A321 to meet the needs of the NETRA system while also accommodating additional power sources and cooling systems for the radar and onboard sensors, which have considerable power demands. The Airbus platform thus becomes a high-endurance, long-range asset for surveillance and reconnaissance.

Multi-Role and Enhanced Surveillance Capabilities

The NETRA AEW&C Mk2’s value extends beyond radar technology. This platform is equipped to operate as a mobile command center, directing both air and maritime operations and coordinating multiple platforms. With its advanced sensor systems, it can pinpoint the location of hostile aircraft, ships, and missiles, all while maintaining secure communications with other Indian assets. The Mk2 model thus plays a key role in joint operations by bridging data and communications among IAF and Indian Navy assets.

The platform also features electronic intelligence (ELINT) and communications intelligence (COMINT) capabilities, collecting and analyzing signals from hostile forces and providing IAF commanders with invaluable intelligence. These advanced systems allow the NETRA Mk2 to function not only as an early warning system but as a comprehensive command-and-control center in the sky.

Building a Fleet for the Future

India’s ambitious expansion of its airborne surveillance network is notable. The IAF is planning to add 12 AEW&C Mark-1A and Mark-2 platforms by the 2030s. These aircraft will join the current fleet of three NETRA Mk1 AEW&C systems and three Phalcon AWACS units, creating a formidable airspace monitoring network across the Indian subcontinent. This fleet expansion aligns with India’s goal of establishing a robust, self-reliant airborne surveillance capability capable of deterring and responding to any regional threats.

Strategic Collaboration and Indigenous Development

The DRDO-Airbus partnership reflects India’s strategy to strengthen its indigenous defence manufacturing sector while harnessing the expertise of global aerospace leaders. The modifications undertaken by Airbus enable DRDO to implement the full suite of NETRA’s systems within a reliable and tested platform, reducing the program’s development time and enhancing its operational readiness. With the A321 platform’s proven reliability and the high-tech modifications from DRDO, the Mk2 model showcases the blend of foreign collaboration and domestic innovation crucial to India’s defence strategy.

India’s NETRA AEW&C Mk2 model represents a significant advancement in India’s military technology. With its powerful Uttam radar, modular A321 platform, and comprehensive suite of electronic warfare and command systems, this airborne early warning system is poised to become an indispensable asset for the Indian Armed Forces, cementing India’s stature in regional defence and surveillance capabilities.
