Hot Air had this post the other day. According to Danger Room, the modified 747 is supposed to start test-zapping missiles next year. They’ve been working on this one for a while, and it seems they’re getting close.
This could be huge, if it works as planned. The combination of the ABL orbiting near a danger area, and the Navy’s newly well-tested missles to shoot down anything that slips by, could very well keep us, and Europe safe from whatever the Iranians, Russians, or Chinese might want to sling our way.
