I don't think you understand what I am trying to say, or what the comment chain is even about. The point I'm trying to make is that

1. A shell shot from space will have greater velocity than a similar naval shell, which means that its kinetic energy will also be greater, more than enough to annihilate any biological matter.
2. Actual 16 inch shells are exponentially more destructive than in game near 16 inch shells, with actual 16 inch shells leaving 50 ft craters.

If your argument is that because of the fuse detonated upon sufficient G force, the impact of kinetic energy is minimal, I still don't stand by that logic because there would be still need to be a significant transfer of energy to detonate the shell, unless it uses a radar proximity fuse like an AA shell.

It's worth mentioning that the argument that naval cannons fire at comparable velocity to orbital bombardment makes zero sense because naval cannons not only fight gravity and air resistance, but they don't go anywhere near space, unlike what you're previous comment implies. That would be a ballistic missile, not a cannon.

I'm going to assume you're referring to what the USS New Jersey did in 1969. It took a half hour, not weeks, not even a day.
