Drone-Mounted Laser Weapons Are On the Way

Daniel_Stuckey writes "DARPA is funding research into drone-mounted laser weapons. The project, called Endurance, is referred to in DARPA's 2014 budget request as being tasked with the development of 'technology for pod-mounted lasers to protect a variety of airborne platforms from emerging and legacy EO/IR guided surface-to-air missiles.' The budget explains that it will be the first application of DARPA's much-discussed Excalibur laser defense system, which developed lasers powerful enough to use as weapons. With the new program, DARPA is focused on miniaturizing the technology, as well as 'developing high-precision target tracking, identification, and lightweight agile beam control to support target engagement. The program will also focus on the phenomenology of laser-target interactions and associated threat vulnerabilities." In other words, DARPA hopes that drone-mounted lasers will soon be able to shoot missiles out of the sky."

Power source? I am immediately struck by the design obstacle of stashing enough power capacity onto a 140 hp propeller UAV. Even if designers manage to get enough power stored on board, it will most likely result in the drone being limited to a single blast (while seriously degrading operational range).

The problem is the arms race.

Except, as I just mentioned, a reflective surface would be a piss poor defense against a laser. Between dust, condensation, wavelengths, and the fact there's no such thing as a perfect reflective surface it would be mostly pointless. An ablative surface, such as the space shuttle used, would be a significantly better defense.

How much power does it take to punch through a metal casing? We already have laser pointers that can burn through paper and thin pieces of wood.

With a beam of light? A lot. Check out the latest demos of ground-based missile defense lasers. The power sources (and related cooling) for those are in trailers hauled around by 18-wheelers. Doesn't sound like something you'll be able to fit on a drone any time soon.
