Was about post this, good that you did.
Take our Indian media to be trigger happy idiots, and goofs with nil knowledge of Defense.
They took the test bed name, and gave it to the radar. Its just Uttam Mark 3 , Uttam Mk1 and Mk2 will go on Tejas Mk1 and Tejas Mk2.
This is a great opportunity to clear all misconceptions regarding Uttam Radar
1.
Uttam mk1 (768 TR Modules) GaAs based, although intended for Tejas mk1a but was only used for testing purposes and will never go into production because GaAs technology has started to become obsolete.
2.
Uttam mk1a (912 TR Modules) GaN based, has more TR modules than the baseline uttam mk1 due to them being more closely packed.
Is intended for Tejas mk1a, can be seen flying on LCA PV's all the time.
All Tejas mk1a's onwards the 21st one (or 41st one I'm not sure) will come with this version of the Radar
3.
Uttam mk2 (992 Tr Modules) GaN based, Intended for Tejas mk2, has completed all of its preliminary testing and does not require anymore testing, it's software is being optimised on uttam mk1a which as earlier stated is flying on Tejas PV's
4.
Uttam mk3 (nearly 2000 TR Modules) GaN based, intended for Su 30mki and AMCA.
Is undergoing preliminary testing on the Hawker 800 based test bed called Virupaksha.
Hope this clears any and all confusions of all the members of PDF
