Pentagon Eyes Laser-Armed Drones to Shoot Down Ballistic Missiles

January 20, 2016

Defense One:

Four years after the Air Force’s missile-zapping Boeing 747 went to its final resting place in the Arizona desert, the Pentagon is thinking anew about airborne lasers that shoot down ballistic missiles. This time, they’d be mounted on smaller, higher-flying drones.

The idea has been around for decades, but the Pentagon’s missile defense chief says its time may have come. The plan is to see how the laser technology matures over the next three years to fit it on a high-altitude drone, Vice Adm. James Syring, the Missile Defense Agency director, said Tuesday

“We have significantly ramped up our program in terms of investment and talking about it more of what else needs to be done to mature this capability,” Syring said at a Center for Strategic and International Studies event in Washington.

Such drones would be designed to fly at 65,000 feet or higher, far above bad weather. They would stay aloft for days, even weeks, loitering around launch sites so they could fire upon enemy missiles as they lift off.

The military has long sought a way to get at ballistic missiles in their vulnerable “boost phase,” drawing a bead on them before they reach full speed, deploy decoys, or take evasive action. The Pentagon spent 16 years and $5 billion building the Airborne Laser, a heavily modified Boeing 747 jetliner with a bulbous chemical laser on its nose. In 2010, it shot down a missile in a test.

“It proved that this this concept could work,” Syring said. “It proved that, given enough power, given enough beam quality, given enough altitude, intercept of a ballistic missile … [at a] wide variety of ranges would theoretically be possible.”

But the Airborne Laser’s short range required it to be so close to a launch site that it would expose itself to enemy fighter jets or ground fire. And providing round-the-clock defense would have required small fleets of 747s plus fighter jets for protection and tanker aircraft to keep everything fueled up.

Then there was the laser itself. Powered by chemicals, the laser and its support equipment was comparable in size and weight to six Chevrolet Suburban SUVs. Each time the laser was fired, the plane would need to land to have its chemicals refueled.

It was “hard to maintain a chemical laser,” Syring said…
