Yes, unguided ballistic missiles are that inaccruate. They are area weapons; meaning you are aiming them at a point on the map and they will land within a somewhat-predictable area. Hitting a specific point target is either a matter of coincidence or saturation. When the US introduced modern guided munitions during the First Gulf War it was a complete game changer, and we've led the way in their development since.
Well, a dozen missiles isn’t saturation, is it?
I dunno. It doesn’t sound like a lot if they’re unguided and that would maybe explain the lack of casualties?
Again, I know nothing of these things.
Thanks.
If you want to use dumb missiles then you launch them in vast quantities. In hundreds or thousands, like the Russians did in WW2. The Iranians have thousands. It does appear that the recent launchings were face-saving because a handful of dumb rockets achieve next to nothing. Just my take.
