Missile Defense Agency has new hope for airborne lasers

Airborne lasers are back in the sights of the Missile Defense Agency — a decade after the first attempt to build a system collapsed, having swallowed 16 years and $5 billion in research and development.

This time, however, MDA is taking things slow. Rather than jumping straight to shooting down missiles in space, the agency is first focusing on using low-powered lasers for tracking and working its way toward higher-powered systems for intercept.

“Tracking characterization work will grow MDA’s capabilities for the use of low-power tracking lasers. The systems associated with this risk reduction work are also directly applicable to more advanced systems, including non-kinetic intercept systems,” an agency spokesperson told Breaking Defense.

“MDA’s approach is to progress technology development and demonstrations for near term missions like tracking while higher power lasers required for the future are in development by [the Pentagon’s Office of Research and Engineering]. MDA and the Department are working toward future directed energy systems which have lower size, weight, and power, to support mobility and maximum proliferation across the battlespace,’ the spokesperson added.

One of the reasons that MDA is focusing on airborne systems, the spokesperson explained, is that such a system could provide advantages for research and development activities over both ground-based and space-based missile defense approaches.

“An airborne directed energy technology demonstrator provides favorable environments and ranges over ground based systems; it provides iterative directed energy technology development flexibility not offered by space based systems,” they said.

MDA Director Lt. Gen. Heath Collins told the Center for Strategic and International Studies on June 6 that the agency asked for $11 million in research and development money to explore airborne laser technology, starting with tracking. The effort builds off of recommendations from an independent team of government, industry and academic experts, he said.

Asked for details about the make up of the study group and the report, the MDA spokesperson said only that the report has been designated Controlled Unclassified Information and will not be released.

New Lasers Open Up New Possibilities

Mark Lewis, who served as the Pentagon’s senior scientist in 2020 and now is CEO of the Purdue Applied Research Institute (PARI), gave MDA a thumbs up for taking a new look at the concept, noting that the technology has come a long way since 2014. Not only are there new power sources for lasers, but also improvements have been made to technologies for beam stabilization and cutting through the Earth’s atmosphere, he explained.

“I would argue that … even though airborne laser was, how do I say this diplomatically, not a success, there’s actually value in going back and revisiting, and asking, ‘Well, have things changed?’ So good on MDA,” he said.
