In a major boost to India's indigenous defence capabilities, the first batch of the domestically developed Uttam Active Electronically Scanned Array (AESA) radar is scheduled for delivery starting in 2026.
This initial set of approximately 33 radars, produced through a collaboration between the Defence Research and Development Organisation (DRDO) and private industry, will be integrated into the Tejas Mk1A Light Combat Aircraft (LCA).
This development marks a critical achievement for the 'Atmanirbhar Bharat' initiative, significantly reducing dependency on foreign suppliers for crucial fighter jet technology.
The Uttam radar system is a sophisticated piece of technology that enhances a pilot's situational awareness and the aircraft's combat effectiveness.
Under the current production plan for the Tejas Mk1A, the first 40 aircraft will be equipped with the Israeli ELTA ELM-2052 AESA radar. This transitional measure ensures that the aircraft production timeline, managed by Hindustan Aeronautics Limited (HAL), proceeds without interruption.
From the 41st jet onwards, the indigenous Uttam radar will become the standard fitment.
Developed by DRDO's Electronics and Radar Development Establishment (LRDE), the Uttam is an advanced X-band radar.
Unlike older mechanically scanned radars that physically move to direct the radar beam, the Uttam AESA radar steers its beam electronically. This allows for instantaneous tracking of multiple targets, superior resistance to electronic jamming, and the ability to conduct simultaneous air-to-air, air-to-ground, and air-to-sea operations.
The radar system is built with 912 transmit-receive modules, which are key to its high performance.
The successful integration and operationalisation of the Uttam radar in the Tejas Mk1A fleet are expected to have a cascading effect on India's future military aviation projects.
It is slated for use in the more advanced Tejas Mk2 and the futuristic Advanced Medium Combat Aircraft (AMCA), India's fifth-generation fighter program.
Furthermore, the modular design and advanced capabilities of the Uttam radar position it as a strong candidate for export to friendly nations, potentially elevating India's status in the global defence market.
The incorporation of this cutting-edge, home-grown radar will provide the Indian Air Force's 4.5-generation Tejas Mk1A jets with a significant technological edge, making them more formidable assets for national defence.
