Why SRBMs with passive radar homing were not intorduced?
I think that it could be done with WW2 tech.
Certainly states with Scuds could lump one its enemies to supress radars?
Iraq, Egypt, Syria all could have used such tweaked Scuds for great efect.
Espacially in 60s-80s when not many SAMs had ABM capability it could do great trick.
