Responding to lawmakers' questions about how close the Army is to developing offensive and defensive directed-energy weapons, Mary J. Miller responded: "I believe we're very close." Miller, deputy assistant secretary of the Army for Research and Technology, testified before the House Armed Services Committee's Subcommittee on Emerging Threats and Capabilities recently regarding the Army's Science and Technology (S&T) Program for fiscal year 2017.

The Army's S&T effort is committed to pursuing high-energy lasers, she said. That effort has been used in an analysis of alternatives for the Indirect Fire Protection Capability program of record. That effort has now been "aligned to transition into a program of record in the fiscal 2023 timeframe," she said. It's already planned and funded.

It will take that long because it's being done in a "step-wise demonstration of capability," she explained. "We have to make sure the lasers work and do the full set of scopes against the threats we project. And those threats include the counter-rockets, counter-artillery and counter-mortar as well as [Unmanned Aerial Vehicle] and cruise missile threats."

Miller explained that the Army wants to understand the lasers' full capabilities "before we offer it to a soldier," because operators need to trust what lasers can do. "Lasers have been promised for a long time, but they've never held up and delivered what was asked for, so the operators are rightfully skeptical," she pointed out. That's why the Army is taking lasers out into operational environments and testing them. In the meantime, "there will be steps along the way where we spin off lesser capable laser systems that can do good things on smaller platforms. Those will come out soon," she concluded.

Dr. David Walker, deputy assistant secretary of the Air Force for Science, Technology and Engineering, Office of the Assistant Secretary of the Air Force for Acquisition, agreed with Miller's logic for step-wise rollouts. "We too have spun off lesser-capable laser systems," he said, following Miller's remarks.

The Air Force is flying every day with lasers under its transport aircraft, using them as infrared countermeasure system," so we too spun off lesser-capable laser systems and as we get larger power outputs and better thermal management out of smaller package lasers, we will build those powers into defensive to offensive capability as well," Walker said.

Walker also said the Air Force is working with Special Operations Command to develop an offensive laser that will be fitted to AFSOC AC-130 gunships. Part of that technology, he said, includes "beam-steering and power and thermal management." The Navy's science representative described similar laser programs for ships, subs and Marines.
