At high altitudes of 3,000 m, it navigates with a visual positioning system using roads and other visible landmarks. A video link option is available so an operator can manually guide the drone to hit moving targets, but this adds costs and only works at shorter ranges. The basic Scythe airframe costs USD $15,000, which increases to USD$30,000 with a guidance system and other features; this compares to around USD$20,000 for a Shahed-136 one-way attack munition used by Russia . Swarms can use a leader-follower method, where one lead drone carrying a navigation system is followed by nine basic drones, which help saturate the target area and draw off enemy defenses from the lethal version.
