India’s Radar Modernisation Driven By DRDO Uttam AESA And Israel’s EL/M-2052 AESA Radars

India’s radar modernisation plans are formed by two essential AESA radars—the
indigenous DRDO Uttam AESA and Israel’s EL/M-2052, every reflecting a distinct
strategic path.

AESA know-how itself marks a generational leap, changing mechanically
scanned radars with electronically steered beams that permit quicker goal
detection, simultaneous multi-mode operations, low interception chance,
and robust anti-jamming resilience.

The Uttam AESA, developed by DRDO’s LRDE, is on the coronary heart of India’s
self-reliance drive. Constructed round solid-state GaAs transmit–obtain modules,
it helps over 50 simultaneous goal tracks, multi-role modes together with
air-to-air, strike, SAR mapping, and built-in EW capabilities, all inside a
modular open-architecture design scalable for fighters like TEJAS MK-1A,
Su-30MKI, AMCA, and future UAVs.

Presently in superior trials with formal integration into TEJAS MK-1A already
cleared, Uttam goals to supply India not simply radar autonomy but additionally long-term
value effectivity and deep compatibility with indigenous digital warfare
frameworks, guaranteeing independence from exterior disruptions.

The EL/M-2052 by Elta Programs, Israel, represents a combat-proven and
export-successful AESA radar, already fielded throughout Indian Jaguar DARIN-III
upgrades and provided for MiG-29 and Tejas platforms.

With a demonstrated vary of over 150–200 km in opposition to fighter-sized targets,
capability to trace 60+ aerial objects concurrently, and a number of operational
profiles together with maritime surveillance and terrain-following, it has constructed a
fame for top reliability throughout numerous situations.

Its main benefit lies in confirmed efficiency, intensive logistical assist,
and instant availability, making it optimum for fast operational upgrades
in legacy fleets.

A direct comparability highlights that each radars occupy overlapping efficiency
brackets—notably in goal monitoring and multi-role versatility—however differ
in maturity and ecosystem energy.

EL/M-2052 at the moment surpasses Uttam in detection vary and fight validation,
whereas Uttam provides strategic advantages of sovereignty, future scalability into
Fifth-gen platforms, and decreased lifetime prices as a result of native assist chains.

For India, the implication lies in steadiness: EL/M-2052 can ship instant
functionality for ageing fleets like Jaguars and probably MiG-29 upgrades,
guaranteeing no operational gaps, whereas Uttam progressively matures into the radar
spine of next-generation fighters resembling TEJAS MK-1A, AMCA, and TEDBF.

This hybrid strategy of overseas stopgap and indigenous indigenisation permits
the IAF to take care of short-term readiness whereas constructing long-term independence
in a vital area of recent aerial warfare.

Detailed platform-specific roadmap comparability displaying how DRDO’s Uttam AESA
and Israel’s EL/M-2052 radars may very well be distributed throughout the Indian Air Drive
(IAF) and Navy fighter fleets:
