India’s ambitious fighter jet programs, the Tejas Mk1A and Tejas MkII, are set to share the same state-of-the-art Uttam Active Electronically Scanned Array (AESA) Fire Control Radar, underscoring a focus on commonality and advanced technology in the country’s defense aviation sector. This decision not only streamlines production and integration but also enhances the operational capabilities of both aircraft platforms.
The Uttam AESA radar, developed by India’s Defence Research and Development Organisation (DRDO), features 912 Transmit-Receive Modules (TRMs) with 896 active elements, and 16 receive-only elements using Gallium Arsenide (GaAs) technology. This radar offers exceptional performance in air-to-air, air-to-ground, and air-to-sea missions, ensuring high levels of situational awareness and targeting precision.
The Tejas MkII radar’s standout capability lies in the modification of the Active Aperture Array Unit (AAAU) interface plate, which will be adjusted with an 8-degree tilt to align with the MkII’s aerodynamic and structural design its rotating repositioner, which allows it to scan a 140-degree search volume within a 200-degree look angle. This functionality significantly enhances the aircraft’s ability to track multiple targets across a wide field of view, giving Indian fighter jets a decisive edge in combat scenarios.
Equipping both aircraft with the same radar ensures reduced development timelines and cost efficiencies while maintaining cutting-edge performance standards. It also simplifies maintenance and training for operators, creating a seamless user experience across the Indian Air Force’s fleet.
