The RQ-1 Predator was the primary remotely piloted aircraft used for offensive operations by the USAF and the CIA in Afghanistan and the Pakistani tribal areas from 2001 until the introduction of the MQ-9 Reaper; it has also been deployed elsewhere. Because offensive uses of the Predator are classified by the U.S., U.S. military officials have reported an appreciation for the intelligence and reconnaissance-gathering abilities of RPAs but declined to publicly discuss their offensive use. The United States Air Force retired the Predator in 2018 replacing it with the Reaper.
