i'm guessing that the original ball was obliterated, but what machine shot it?

turns out, that this is a result from testing impact of space debris, i cannot however find anything regarding the size of the ball or plate, but for shielding purposes, i doubt this was "12 inches", but not the first time a guy exaggerated

If that is indeed a 12inch thick steel block then that steel shot is approximately 1.9 inches in diameter by my calculations

How'd you pull that number?

I pulled the picture up on my computer and then divided the height of the steel bar (which is allegedly 12 inches) by the height of the steel shot.

See that bulge on the bottom? That's called spalling. That's the principle behind HEAP ammo. It only works on solid armor though, so it's not effective against reactive or layered armor.

"The image above shows a 1.2-cm (0.47-in) aluminum sphere striking a seven inch (18 cm) thick aluminum plate at a velocity of 6.8 km/s (4.2 miles per second), giving some idea of the destructive power of hypervelocity impacts." http://www.gizmag.com/space-debris-kessler-syndrome-nasa-debrisat/24911/

How do you get balls to move that fast?

Magnets. Essentially a rail gun
