In a speech last week before the Veterans of Foreign Wars in Kansas City, President Donald Trump repeated a point he has frequently made about the wonder of American military technology—that the F-35 Lightning II's "super stealth" technology makes it literally invisible.

This is an incredible plane. It's stealth—you can't see it. So when I talk to even people from the other side, they're trying to order our plane. They like the fact that you can't see it.  I said, "How would it do in battle with your plane?" They say, "Well we have one problem—we can't see your plane." That's a big problem. Stealth, super stealth. The best in the world. We make the best military equipment in the world. Also, remember this: jobs.
