Also keep in mind that the target we are talking about here is nothing more than a lump of metal. The lump of metal can be bent broken warped twisted or perforated and it retains exactly the same value to the weapons programme (just so long as you can find all the pieces). Designing a strike that can functionally 'destroy' small disks of metal is (I would imagine) not a trivial undertaking, even if you know to the nearest cm where they are.
