Hempy, Ad Hominem to KenV's post isn't helpful chum. Can we all please leave the personal issues at the door now, and perhaps move on with some considered debate? Perhaps it also might help if posters signposted 'fact', 'opinion' or 'guess' behind their posts. That way we don't start demanding evidence or a source behind a held opinion or guess.
Just a thought (opinion)
I also can't see the link between gr's video link and this thread. Other than the fact we have impressive CIWS....
