Looks like damage. Note how a wave is forming on the outer edge of the cavity? That shows it happened after the strike. Kind of like a meteor crater.

@ch27, while it may be rounded, this shape is definitely not spherical. Also, I agree that the metal looks slightly "smushed" up from about 9 to 1 o'clock around this depression.

Not only is there crater edging, the indentation is at an angle. The Rockwell test I would imagine should be a direct straight on hit.

The meteor crater is 3/4 mile wide. The meteor broke up on Impact and pieces expelled out a distance away.
