Drones are unmanned aerial vehicles (UAVs) that are used bythe military in a number of ways, including missile testing, air strikes, aerial refueling, surveillance, transporting cargo, live-fire exercises and even long-range bombing. The U.S. military began experimenting with unmannedaircrafts as early as World War I, but they were called remotelypiloted vehicles (RPVs) at the time. Today, UAVs are used by various organizations, including the U.S. Air Force, Navy and the U.S. Geological Survey.
