The US Air Force just edged closer to its goal of outfitting aircraft with laser weapons. Testers at the White Sands Missile Range have successfully shot down multiple air-launched missiles using the Self-Protect High Energy Laser Demonstrator (SHiELD), proving that it can hold up under intense situations. While SHiELD is currently a ground-based behemoth (see below), the finished technology should be portable and rugged enough to be used aboard aircraft.
