A couple of things:
The press release you sited from Boeing was 2012. It was public, not classified.
This is old technology in a big way. I’m VERY happy to see we’ve got something like this, and I suspect something like this was used by Israel against the Bushear nuclear facility a ways back.
I don’t want to know if there is a counter to this that we’ve got, or whether the Chinese/Russians have something similar/better than CHAMP.
