How difficult is it understand for you ?. India is not buying Derbies in future..
I-Derby range is 80-90 km
Derby ER range is 100 km.
Astra MK1 is already better than both. MK1 will replace all other BVR of this range in future.
MK1 is already integrated with SU 30.
For the rest of the fleet process is going on.
You answered the point. "In the future"
Until then SU-30s basically are outranged by AMRAAM and PL-15. Just like in 2019....
