A KZO system consists of 10 UAVs and 2 ground units, consisting of one control station, one radio, one launch, one maintenance vehicle with a refuelling facility for the UAVs and one recovery vehicle. The UAV is launched with a booster rocket directly out of its container. Landing is done with a parachute. The KZO's main objective is to locate mobile threats and provide target locations for artillery. KZO replaced the German Army's other main UAV, Drohne CL 289. Two electronic warfare variants have also been developed as the Mücke ("mosquito") and the Fledermaus ("bat").
