What is a UAS/UAV? The UAV is an acronym for Unmanned Aerial Vehicle, which is an aircraft with no pilot on board. UAVs can be remote controlled aircraft (e.g. flown by a pilot at a ground control station) or can fly autonomously based on pre-programmed flight plans or more complex dynamic automation systems. UAVs are currently used for a number of missions, including reconnaissance and attack roles. A UAV is defined as being capable of controlled, sustained level flight and powered by a jet, electric, or reciprocating engine. In addition, a cruise missile can be considered to be a UAV, but is treated separately on the basis that the vehicle is the weapon. The acronym UAV has been expanded in some cases to UAVS (Unmanned Aircraft Vehicle System). The FAA has adopted the acronym UAS (Unmanned Aircraft System) to reflect the fact that these complex systems include ground stations and other elements besides the actual air vehicles.

UAS Types by mission Target and decoy - providing ground and aerial gunnery a target that simulates an enemy aircraft or missile. (first used WW2) Reconnaissance - providing battlefield intelligence (most common) Combat - providing attack capability for high-risk missions (see Unmanned Combat Air Vehicle, (UCAV) Research and development - used to further develop technologies to be integrated into UAS aircraft Civil and Commercial UAVs - UAVs specifically designed for civil, and potential commercial, applications such as agriculture, forestry, etc.
