A Complementary Red-Zone Defense for C-UAV Systems

Weaponized drones, as in common multirotor-type hovering drones, are emerging as a disruptive threat for any combat scenario. Swarms of these drones present a particularly difficult battlefield challenge, as they threaten the real possibility of overmatching Counter-Unmanned Aerial Vehicle (C-UAV) defensive systems, by virtue of sheer numbers. There are some excellent C-UAV systems deployed, or nearing deployment. And many more are under development. An exemplary system uses RF suppression/jamming to degrade the remote control ability of the UAV, combined with a powerful laser aligned to a radar tracking system, to destroy the drone if necessary. These systems appear to be reasonably effective in single drone encounters, in which the drone is willing to hover or fly a predictable trajectory while the laser can be trained on it. However there are some troubling realities to be considered in an actual battlefield scenario. For one thing, C-UAV systems are radically more expensive and complex than drones, so there will be orders of magnitudes more drones than C-UAV defensive installations. The cost and complexity of C-UAV systems limits their deployment on, for example, ground vehicles. In any ground combat scenario there will be many vehicles without C-UAV systems installed. Should for example any of the drones in an attacking swarm get through the defensive screen of the on-scene C-UAV system (assuming there is one), those vehicles would have no protection at all, and would be easy kills. Additionally, available information seems to indicate that the laser kill function of a typical C-UAV system requires that the laser be on the drone continuously for several seconds, in order to produce enough functional damage to bring the drone down. An obvious tactic to counter lasers would be to simply program the drone to fly a randomized, slightly erratic course to target. This would challenge even the most sophisticated tracking and aiming system, and would likely result in a reduction of effectiveness of the laser kill system. Such programming mods could be embedded in the drone’s own hardware, thus mitigating RF disruption. In a swarm attack, there may simply not be enough time to burn holes in all of the drones before they reach their targets. Many more potential loopholes to current C-UAV systems may be envisioned, but the larger point is that it seems likely that a swarm of drones could have at least some success penetrating current C-UAV architectures.

This points to the need for a simple and cheap kinetic close-in defensive system, to be used in conjunction with C-UAV systems as a complementary “red zone defense” against any attacking drones that penetrate the wider-area defensive dome. This system would need to be simple and inexpensive enough to mount on any vehicle or defended installation. Ideally the system would also provide defense against other common asymmetric threats, such as RPG’s.

The Active Rotating Countermeasures (ARC) System represents a simple, inexpensive kinetic close-in defensive system. As a “last resort” line of defense the ARC system could complement current and future RF / Directed Energy C-UAV systems. An individual-target defensive capability, the ARC system is suitable for mounting on any vehicle. The kinetic defensive requirements at very short ranges consist of very quick aiming, barrier overkill, and the ability to address multiple threats simultaneously (from different directions). The ARC system fulfills these requirements in a simple architecture. The ARC system features a modest energy budget and is designed for reasonable acquisition and maintenance costs. The ARC system also offers the flexibility to deploy a variety of countermeasures, and the development potential to keep pace with the evolution of battlefield threats.

Primary Components

There are two primary components in our active countermeasures system: One is a continuously rotating turret that through its LIDAR interface can release a countermeasure faster and defeating incoming ordinance further from the vehicle, cutting down concerns over fratricide, or collateral damage. The turret features over a dozen individual countermeasure launchers and is capable of defeating multiple threats, simultaneously.

The second component is the munition. Unlike current “shotgun” type solutions to RPG defense, our solution utilizes a rocket towed barrier (RTB) that is able to deflect incoming ordinance from its primary flight path, rendering it ineffective or disabling it entirely. In this system there is no explosive munition and no significant danger to friendly troops.

Active Rotating Countermeasure (ARC System)

Aka. “The Turret”


The rotating launcher spins constantly, and can deliver ordinance faster defeating objects further away than current Active Countermeasure solutions

Rocket Towed Barrier (RTB) Munition

Illustrated Battlefield Scenario


Munitions used in the turret can take on many forms including that of a kevlar parachute towed by a rocket with a wide, non-lethal RPG intercept range.

Notional Deployment

The ARC system coupled with the RTB (Rocket Towed Barrier) is suitable for deployment on any VTOL aircraft as well as land vehicles.
