New data shows the U.S. Air Force is increasingly relying on drones, rather than manned aircraft, in the ongoing war in Afghanistan. In 2015, drones released 530 bombs and missiles in Afghanistan. This accounts for 56 percent of the weapons deployed by the U.S. Air Force. In contrast, in 2011, drones were used for only 5 percent of the weapons deployed by the Air Force. President Obama had previously said the 2014 drawdown would “reduce the need for unmanned strikes.”
