These are two entirely separate streams of developments. Can’t see why failure or success in one is related to another.That’s true for cruise missiles. But Rudram family is of ballistic missiles. This shows that DRDO has again failed to make a cruise missile and the missile will be converted to a ballistic missile only. Practically it’s a longer ranged guided Pinaka.
BTW, Nirbhay been deployed in limited numbers since Galwan incident.
