Scale Model of Tejas' Uttam Radar, Featuring Multi-Target Tracking and 95% Indigenous Tech, to be Displayed at Aero India 2025

The Defence Research and Development Organisation (DRDO) is poised to impress at Aero India 2025 with a scale model of the Uttam Active Electronically Scanned Array (AESA) Radar, designed for the Tejas MkI and MkII fighter jet programs. This event, held in Bengaluru, will serve as a prominent showcase for India's advancements in indigenous defence technology.

The Uttam AESA Radar represents a significant leap forward in radar technology for the Tejas light combat aircraft. Developed by the Electronics and Radar Development Establishment (LRDE), a DRDO laboratory, the radar offers superior air-to-air, air-to-ground, and air-to-sea operational capabilities.

With features like multi-target tracking, electronic counter-countermeasures (ECCM), and low probability of intercept (LPI), the Uttam radar is set to significantly boost the combat effectiveness of the Tejas.

Key features of the Uttam AESA Radar include:

• Scalability: The radar's design allows for adaptation to different aircraft sizes, making it suitable for both the Tejas MkI and the more advanced MkII, and potentially other platforms in the future.
• High performance: It boasts a detection range exceeding 100 kilometers against fighter-sized targets, with the ability to track multiple threats simultaneously and engage priority targets with precision.
• Indigenous development: Approximately 95% of the radar's components are indigenous, aligning with India's drive for self-reliance in defence technology.
• Integration with Tejas: Plans are underway to integrate the Uttam AESA Radar into later batches of Tejas Mk1A aircraft, with successful testing already conducted on prototypes, demonstrating its readiness for deployment.

The display of the Uttam AESA Radar at Aero India 2025 will highlight India's growing capabilities in developing advanced defence technologies. This radar is a testament to the country's commitment to self-reliance in critical areas and its ability to produce cutting-edge systems for its armed forces.

Good News, with 95% Radar componets are Indigenous thats sound Good hope remaining 5% would soon b Indigenous one

When will it be production ready?

Another scale model? Fantastic! Seriously, does anyone know how I can send the RC plane I built a few years to Aero India as well? The model is of a Spitfire (mostly), and actually flies, so it is better than these models, I guess.

When will it be production ready?

This is one are we can expect everything to go smoothly. Be it Uttam or Ati Uttam or Virupaksha LOL. Extracting more power from engines to get the most out of the radar is another matter altogether.

If they can somehow negotiate with the French to test an Uttam variant from the Rafale, that will be big victory. We can even share some of Uttam's technology with them in exchange for secret submarine/nuclear or aero engine tech.

I congratulate DRDO for giving us scale model of Uttam Radar. 51st Mk1A will have Uttam radars, that means DRDO has around 5 years to build and perfect it assuming they supply 10 per year.

Rafale uses Vivaldi TRMs which are much more advanced compared to the Slot/Patch type used in Uttam.

So that's a no go.

Not in this decade

Lol...Uttam itself is based on the French tech we got during the Rafale offset deal. So sharing it back is kind of boastful.
