== Description ==
It is a liquid cooled AESA radar featuring quad band modules that can be stacked to form a larger unit. This allows the manufacturer to scale the radar to be used in larger aircraft. There are plan to create a larger scalable design to be used in [[India]]'s fifth-generation HAL AMCA jet fighter.<ref name="uttamaerojournal">{{cite web|title=Uttam AESA radar: Everything you need to know|url=http://www.aerojournalindia.com/enews/?p=2914|access-date=14 January 2019|publisher=Aero Journal India}}</ref>

The radar development began in 2012 and its full-scale model was displayed at the 2017 [[Aero India]] air show and aviation exhibition.<ref>{{cite news|title=Uttam AESA radar ready for induction in Tejas MK1A|url=https://defenceview.in/uttam-aesa-radar-ready-for-induction-in-tejas-mk1a/}}</ref> A fully functional AESA radar prototype was unveiled at Aero India 2019, the prototype was mounted inside the glass nose of a HAL Tejas prototype.<ref name="uttamaero19">{{cite web|title=India Displays Locally-made AESA Radar for Tejas Jet at Aero India 2019|url=https://www.defenseworld.net/news/24318/India_Displays_Locally_made_AESA_Radar_for_Tejas_Jet_at_Aero_India_2019#.Xp_nUZrhWV4|access-date=20 February 2019|publisher=DefenseWorld}}</ref> As of 2021, three units were in various phases of testing,. The Uttam radar has completed 230 hours of airborne testing onboard two Tejas fighter jets (LSP2 and LSP3) and on an executive jet; presumed to be DRDO's [[Dornier 228]] "Nabhratna" used as a flying test bed by LRDE.<ref>{{cite news|title=Exclusive: Why desi Uttam AESA radar is a game-changer|url=https://guardingindia.com/exclusive/exclusive-why-desi-uttam-aesa-radar-is-a-game-changer/}}</ref> Once fully validated and certified, it is planned is to introduce the radar in later batches of Tejas Mark 1A aircraft.<ref name="uttam-mk1a" /><ref>{{cite web|title=HAL cuts its profit on Tejas Mark 1A deal by 50%, fighter jets to take to sky by 2022|url=https://theprint.in/theprint-essential/hal-cuts-its-profit-on-tejas-mark-1a-deal-by-50-fighter-jets-to-take-to-sky-by-2022/383730/|access-date=19 March 2020|publisher=The Print}}</ref> The Uttam radar will be used with DRDO's Unified [[Electronic Warfare]] suite.<ref>{{cite web|title=Single Engine Fighter Cancellation Provides An Opening For Tejas MK-2|url=http://delhidefencereview.com/2018/02/26/single-engine-fighter-cancellation-provides-an-opening-for-tejas-mk-2/|access-date=26 February 2018|publisher=Delhi Defence Review}}</ref>

During Aero India 2021, there was a licensing agreements for [[technology transfer]] from DRDO to [[Hindustan Aeronautics Limited]] for manufacturing and integration of the Uttam in the Mark 1A variant of the HAL Tejas.<ref>{{cite web|date=5 February 2021|title=DRDO hands over Licensing Agreements for Transfer of Technology for 14 technologies to 20 industries|url=https://pib.gov.in/PressReleasePage.aspx?PRID=1695630|publisher=PIB}}</ref>

[[Indian Air Force Test Pilot School]] will start final demonstration trial of Uttam AESA radar from December 2021 and if successful will be sent for serial production. As per Project director D Seshagiri of [[Electronics and Radar Development Establishment]] (LRDE), Uttam AESA radar is 95% indigenous, with only one imported subsystem. The radar has the capacity to track 50 targets at a range greater than 100 km while engaging 4 targets simultaneously. All 83 [[HAL_Tejas#Tejas_Mark_1A|Tejas Mark 1A]] and [[HAL AMCA|AMCA]] will come equipped with this radar. Uttam AESA radar will also be installed into upgraded [[Sukhoi Su-30MKI]] and [[Mikoyan MiG-29K]] currently in use as front line platform of [[Indian Air Force]] and [[Indian Navy]]. [[Hindustan Aeronautics Limited]] is the lead integrator and [[Bharat Electronics]] is major supplier of subsystems. LRDE already completed 250 hours of performance testing on two Tejas fighters as well as [[Hawker 800]] executive jet. National Flight Testing Centre had evaluated the radar and cleared it after performance tests. The integration problem of [[Astra (missile)|Astra BVRAAM]] due to older generation of radars will also be solved by Uttam.<ref name=":0">{{Cite web|last=Gupta|first=Shishir|date=2021-12-08|title=India develops AESA radar to make IAF fighters more lethal|url=https://www.hindustantimes.com/india-news/iaf-to-showcase-use-of-indigenous-aesa-radar-101638924141445.html|url-status=live|access-date=2021-12-08|website=Hindustan Times|language=en}}</ref>
