Why lol you have scram jet engine in those missiles and Scram is capable of intercepting fast targets only and is not good for slow ones. If a fast target has a trajectory changing capability it cannot intercept. Sacram jet is only fule efficient at a speed of above mach 3. your missiles are fired with a rocket booster to achieve a start speed for a scram jet engine
With my own eyes, I have witnessed Barak 1 intercepting a sea skimming P-20 missile at 7 NM range.
