The Air Force is relying increasingly on the unmanned MQ-1 Predator aircraft to conduct combat air patrols in Iraq and Afghanistan. Predators now provide more than 13,400 hours of video, with the capability of hitting enemy targets with AGM-114 Hellfire missiles – doubling the workload they carried in May 2007. The aircraft are launched by crews at CENTCOM bases in the combat theaters, and operated by other crews at bases in the U.S. The Air Force plans to expand Predator training and stand a second squadron early next year.
