It's a PESA radar not AESA because of it's IFF nodes. China bought PESA radar from Russia around early 2000s.
LCA is a Light Combat Fighter, in that role other than Gripen E/F it's the best.
Tejas took around 15 years for actual work (designing, construction, testing) to be done. We were making a 4+ Gen fighter for the first time on our own. It took nearly 12 - 15 years to get the necessary industrial capacity together before work could begin. But today it can arguably be said to be the best in it's class (Gripen C/D, JF 17, F16 A/B and early C variants,etc included) due to the some amazing technologies used.
1. HMDS (Dash Helmet Mounted Display Sights)
2. FLIR/ Passive IRST (Litening Pod)
3. Internal MAWS, RWR, systems
4. High Thrust to Weight Ratio 1.07
5. Very Low Wing Loading (50.7 lbs/sqft)
6. All Axis Digital Flight Control System (Quadruplex Redundant)
7. ELTA 2032 Hybrid Multi Mission Radar (150 KM Air to Air range for 3 - 5 msq target, 300 KM for Air to Ground target the size of tank.)
8. Stealth Composites
9. Very Low RCS (0.3 msq)
10. Very Low Cost ($ 26 million only)
JF 17 has only point 10. to call it's own
It's a two seater!
