10 Things You Didn't Know About Drones - By Micah Zenko | Foreign Policy: The Pentagon now boasts a fleet of approximately 7,500 drones, up from just 50 a decade ago. According to a congressional report, "manned aircraft have gone from 95% of all [Defense Department] aircraft in 2005 to 69% today." Over the next decade, the Pentagon expects the number of "multirole" drones -- ones that can both spy and strike -- to nearly quadruple, to 536. In 2011, the Teal Group consulting firm estimated that worldwide spending on unmanned aerial vehicles will nearly double over the next decade from $5.9 billion to $11.3 billion annually. In the future, drones are projected to: hover just behind infantry soldiers to watch their backs; carry airborne lasers to intercept ballistic missiles; perform aerial refueling; and conduct long-range strategic bombing missions. Given that drones will become cheaper, smaller, faster, stealthier, more lethal, and more autonomous, it is harder to imagine what they won't do than what they will. Whatever limits drones face will be imposed by us humans -- not technology.
