Tests are dun in steps .Also this PDV will form the base for our own Iskander family type of missiles.
DO you think s-300/s-400 type of MDS have nuclear war heads?
How do I know if Russian missiles interceptor used nuclear warhead? US missiles interceptor tested with a very low percentage of success rate. US missile interceptor can only destroy 3 out of 10 incoming missiles with their trial tested and they call it a failure with the system not partially success of the system.
