I was noticing similar question repeating from multiple people on SM.
Not getting into whether the news about nirbhay is correct or not.
Assuming it is true my take is that, it indicates two things:
1) There are targets beyond 500 km range, and IA does not want to follow a ballistic missile trajectory to hit those targets.
2) Since it takes atleast two years to fulfill any purchase of this kind, they are prepping for next round and getting nirbhay in place for next escalation, which is 3 years away anyways.

Nirbhay test soon. Last test before induction...! Whats happening? Everyone thought, Nirbhay prog was closed as a TD & new programs launched for actual CM to be operationalise. Was this the plan all along or its the
#IndiaChinaFaceOff which changed it?
