DRDO to Showcase Uttam AESA Radar for Tejas MkI and MkII at Aero India 2025

India's Defence Research and Development Organisation (DRDO) is gearing up to make a significant impact at Aero India 2025 by unveiling a scale model of the Uttam Active Electronically Scanned Array (AESA) Radar. This advanced radar system, specifically designed for the Tejas MkI and MkII light combat aircraft, underscores India’s progress in indigenous defense technology. The event, hosted in Bengaluru, will highlight the radar's cutting-edge features and its potential to transform aerial combat capabilities.

A Leap in Radar Technology

The Uttam AESA Radar is the brainchild of the Electronics and Radar Development Establishment (LRDE), a prominent DRDO laboratory. With its state-of-the-art design, the radar is tailored to meet the complex operational needs of modern combat scenarios. It supports diverse operational modes, including:

• Air-to-Air: Engaging multiple aerial targets simultaneously.
• Air-to-Ground: Precision tracking of ground targets for enhanced strike missions.
• Air-to-Sea: Monitoring and engaging maritime threats effectively.

Key Features and Specifications

1. Scalability:

   • The Uttam radar is adaptable to various platforms beyond the Tejas MkI and MkII. Its modular architecture ensures seamless integration across multiple aircraft.

2. Performance:

   • Detection range exceeding 100 kilometers against fighter-sized targets.
   • Multi-target tracking capabilities with precision targeting for priority threats.

3. Electronic Warfare:

   • Features advanced Electronic Counter-Countermeasures (ECCM) to counter enemy jamming.
   • Low Probability of Intercept (LPI) to ensure the radar remains undetected.

4. Indigenous Content:

   • Approximately 95% of the radar’s components are sourced domestically, reflecting India’s emphasis on self-reliance under the "Make in India" initiative.

5. Integration Readiness:

   • Already tested on prototypes, the radar is slated for integration into later batches of Tejas Mk1A aircraft.

Role in the Tejas Program

The Uttam AESA Radar will be a core component of the Tejas MkI and MkII, enhancing their combat efficiency and operational flexibility. For the MkII, which is set to feature a more powerful engine and increased payload capacity, the radar ensures compatibility with advanced weaponry and sensor systems. Its inclusion in the Tejas Mk1A will elevate the aircraft's competitiveness in international markets and strengthen the Indian Air Force's operational capabilities.

The Future Potential

The radar’s modular design opens possibilities for deployment in other aircraft, including India’s Advanced Medium Combat Aircraft (AMCA) and Unmanned Aerial Vehicles (UAVs). With continuous upgrades and enhanced performance, the Uttam AESA Radar positions India among global leaders in radar technology.

A Milestone in Aero India 2025

As DRDO unveils the scale model of this advanced radar at Aero India 2025, it will symbolize India’s relentless pursuit of technological excellence in defense. The event will serve as a global stage to showcase not just the radar’s capabilities but also India’s commitment to developing world-class indigenous defense solutions.
