Years ago here, I remember a thread that described a ‘titanium spear’ that when dropped from 20,000 feet could penetrate ___ (don’t remember how far). Anyone heard anymore about that titanium spear?
I am not familiar with a titanium spear but I saw one program on one of the history type channels where we used practice bombs quite a bit as real bombs.
With the guided GPS packs on them, they had enough energy to destroy the target with just kinetic energy without damaging nearby targets.

If I remember correctly it was one of the proposals under Reagan’s Strategic Defense Initiative.
But I think it was to be dropped from space. Classified as a kinetic energy weapon.
The ‘titanium spear’ with a defeated uranium core could be dropped by the thousands over perhaps a tank battalion, the self-guided spear could impale the tank from the top.
A small rocket motor might be added to ignite at the last moment before impact to aid penetration.
