$1.2 billion

For Israel’s “Iron Beam” defense laser. The laser can take out air threats from over four miles away and never runs out of ammo (paywall link). The Iron Beam can destroy threats for about $2,000 a pop (the cost of electricity), compared to $50,000 for traditional missile defense. I hope this is on the U.S. military’s wishlist.
