Maj. Gen. William Hix, director of strategy, plans and policy in the office of the deputy chief of staff (G-3/5/7), said at the Directed Energy Summit March 29 in Washington that some of those directed-energy challenges include improving the mobility, size, weight, power, all-weather capability, and the ability to complement other systems. "There are also some other opportunities out there . . . communications, operations in space, and perhaps, in the deeper future, direct fire," he said.
