Gave us:

This is what is being used in smart munitions now. Survives well over
15,000 Gs.

I saw this in the
"For comparison, dropping a laptop produces a shock of about 2 to 4 g's. "

Where did they come up with that nonsense? Maybe by dropping it into a box
of styrofoam peanuts. Just dropping it a few inches on a hard surface is
many more G's than that. For only 14,000 G's, they must have crashed their
high-speed ordinance into something fairly soft.

The guidance package isn't expected to survive impact with the target; it
just has to make it through launch. Of course, that could be out of a
cannon. I agree about the laptop, though.

Guidance, yes. But what about a detonator for a penetrator bomb? They
have to break through several steel-reinforced floors, detect some
predetermined condition* and then initiate detonation. Those suckers
must be tough. Nearly as dense as M.P.'s skull. ;-)

*Some just count levels (empty space between floors). Others have side
looking sensors to detect occupants, electronic emmisions or some other
target characteristics.
