Definition/Scope: The XM157 Class IV Unmanned Aerial Vehicle (UAV) has a range and endurance appropriate for the brigade mission. It supports the Brigade Combat Team (BCT) Commander with communications relay, long endurance persistent stare, and wide area surveillance. Unique missions include dedicated manned and unmanned teaming (MUM) with manned aviation; Wide Band Communications Relay; and standoff Chemical, Biological, Radiological, Nuclear (CBRN) detection with on-board processing. Additionally, the Class IV has the payload to enhance the Reconnaissance, Surveillance, and Target Acquisition (RSTA) capabilities by cross-cueing multiple sensors. The Class IV can land without a dedicated air field. Development of this vehicle is shared with the Navy's Fire Scout program. FM 3-0 has replaced UAV with UAS, however not all systems have been able to change their signs/names yet.
