A variant of the Phalanx gun was developed for terminal interception,
basically 20k to 80k feet, as I recall, that would put up a wall of
steel in the path of a warhead. It was meant to be sited within several
hundred yards of the warhead's target, typically missile silos or
military bases.

I wonder why larger guns have not been made with more intelligent guided
munitions. You can't beat the acceleration, probably better than THAAD,
and if the shell has its own upper stage and maneuvering thrusters with
a guidance system and a fragmentation warhead, ..... ought to be more
reliable and less expensive than a missile system.
