Indigenous Uttam AESA Fire control radar (FCR) has completed crucial air to air mode trials successfully and by mid of 2021, DRDO is expecting that it also completes its Air to Ground and Air to Sea Mode before it is cleared for production sometime at end of 2021 or in early 2022 said a report prepared by the Delhi Defence Review. Air to Air mode trials made up 80% of the flight trials and major section of the software development required for the program.

Uttam AESA FCR has been tested in Basic and Advance air to air mode in the trials in the last few years, it has been, further fine-tuned with regular software upgrades and scan refinements, and it has shown better search and track results then the Israeli ELTA ELM-2052 AESA FCR found on the Jaguar Ground attack jets.

Uttam AESA FCR is a frontrunner to be equipped on both Tejas Mark 2 and TEDBF jets since both will be using the same Digital flight control computer (DFCC) when they enter production in 2029. While Tejas Mark 1A too will used same DFCC, but it will incorporate Israeli ELTA ELM-2052 AESA FCR but, DRDO has been trying to make available its Uttam AESA FCR earlier so that it can be considered for 83 Mark 1A jets that are to be ordered, even though the final specification configuration has been frozen by the HAL.

DRDO has conducted a technical feasibility study of equipping an upscaled Uttam AESA FCR to replace the present N011M Bars PESA Radar onboard Sukhoi-30MKI fleet and the findings of the study has been accepted by the Indian Air Force (IAF) and it is likely a new antenna with higher solid-state transmit/receive module (TRM) will be designed soon for the Sukhoi-30MKI fleet.

Uttam AESA FCR will likely to be equipped also on IAF’s Mig-29UPG and Mig-29K fleet of Indian Navy. The radar will be identical to the one developed for the Tejas Mark 2 program. TEDBF currently being developed for the Indian Navy will also receive a variant of the Uttam AESA FCR that has been further fine tuned for over the sea operations. Uttam AESA FCR based on the gallium nitride (GaN) technology that is next generation in the radar technology evolution also has been proposed to be equipped on India’s 5.5th Generation AMCA Stealth fighter jet program when it is ready for production in 2035.
