The U.S. currently has several drone interceptor systems, including the Bumblebee V1/V2 physical‑collision interceptors; the Perseus Harpe has a 2-kilometer range and collides with targets, while the Merops/Surveyor high‑speed explosive interceptor drones can destroy one or more drones within range of their explosion.

Bumblebee V1 & V2 are FPV (First Person View) drones that physically collide with incoming drones. Delta does this using video from surveillance drones and Ukrainian troops feeding back to the Delta battle management system by capturing video from surveillance drones to provide overall battlefield data, with all Ukrainian troops using the system. The system detects Russian troop positions and includes them on the battle map in real time. This enables automated warfare, in which enemy targets are assigned to specific Ukrainian units, which then carry out the attacks. This has caused many Russian troops to spend most of their time hiding from the Delta system, because detection usually means death.

Using an AI/Artificial Intelligence system, the Ukrainians can track over 10,000 Russian weapons systems, troop positions, and drone operators each week. The map of these contacts is continually updated as the Russians move or are destroyed. At the same time, Ukrainian commanders can also see the positions and movements of their own troops. This has dramatically reduced the incidents of friendly fire when Ukrainian soldiers are hit by Ukrainian drones or artillery fire.

One of last year’s innovations in drone warfare was the Ukrainian use of AI for drone targeting systems. The AI drone contains a targeting system that finds targets. The AI drone operator confirms which targets are real and, once a target is confirmed, the AI targeting system needs no further communication. It resists all forms of jamming.

FPV drones have radically changed modern warfare. These drones are a perpetual threat to armored vehicles and infantry. Each FPV drone costs less than a thousand dollars. Operators use the drone's camera to see what is below and find targets. Armed FPV operators are several kilometers away to decide when their FPV drones will drop explosives on an armored vehicle, which has thinner armor on top, or infantry in the open or in trenches. To do so, drone operators often work in pairs, with one flying behind the other and focusing on the big picture while seeking a likely target. When the reconnaissance drone finds a target, the armed drone is directed to it. The two FPV drone operators are usually in the same room or tent and can take control of new drones, which are lined up and brought outside for launch when needed. Reconnaissance drones are often unarmed so they can spend more time in the air searching for a target.

The Perseus Harpe Interceptor weighs about 36 kg and has a range of about two kilometers collides with incoming drones. Nearby units supply target information using control systems like Delta.

The Merops / Surveyor Interceptor Drone is a fast propeller‑driven explosive interceptor. Top speed of nearly 300 kilometers an hour/75 meters per second. This interceptor is designed to destroy swarms of Shahed-136 drones. Unfortunately, like most items produced by the American defense industry, each Merops costs about $15,00o and can deal with cruise missiles and large attack drones.
