Reference bmpd: “Mini-UAVs of the RQ-11 Raven family (weight up to 2 kg, range up to 10 km) are manufactured by the American company AeroVironment Inc. for the US Army and Air Force since 2003, and are actively used by Americans in the military campaigns of the last decade. These UAVs are also widely supplied by Americans both on a commercial basis and in order to help other countries (operated in at least 25 states) - in particular, in 2015, the supply of 30 kits for military aid to Ukraine was announced. UAV RQ-11 Raven is considered the most massive military unmanned aerial vehicle in stories (to date, about 25 thousand units have been manufactured). ”
