Drones have emerged as the ultimate disruptive technology for modern militaries, combining low mass-production costs, agile airframes, and rapid deployment for all mission types. Additionally, advancements in non-GPS guidance and fiber-optic-controlled systems have made some drones immune to jamming or spoofing. Where EW (electronic warfare) is ineffective or inapplicable, two kinetic solutions are increasingly used as the last-layer response:

shotguns and net-launchers. 

Let’s talk about them.

Shotguns have presented an “old-school” solution to a modern challenge. Their wide availability, relatively low manufacturing costs (compared to RF jamming weapons), and universal familiarity appeals to operators. Instead of firing a single bullet at a target, shotguns disperse a blast of pellets in a cone-like shape towards the target. This increases hit probability at very short ranges. But shotguns have critical shortcomings that lead to dangerous consequences. 

First, a shotgun’s effective range for engaging enemy drones is typically approx. 5-30 meters. At these distances, a drone struck by a shotgun shell may break apart or even detonate if it carries an explosive payload, creating shrapnel risk to the shooter and nearby personnel. As we’ve seen in recent conflicts, small UAVs have also been a key component in attacks on urban targets within civilian environments. A shotgun, like any rifle, has less relevance in such domains, as the threat of collateral damage or harm to uninvolved parties is too high. Add to that the legal ramifications of using weapons in public spaces, and their effectiveness dwindles even more. Therefore, a countermeasure that retains effectiveness while utilizing non-lethal technology is needed to defend the final layer of drone threats. 

The growing use of nets to intercept enemy drones has gained popularity for their effectiveness and simplistic design. Net-launchers offer a similar capability to shotguns, where instead of a spread of individual pellets, a large net is launched that immobilizes the drone’s rotors and causes it to crash. ParaZero’s DefendAir net-launcher is similar in size and weight to modern shotguns, has a competetive effective range of up to 35 meters, and has low training requirements. But most importantly, the net-launcher utilizes a non-lethal and non-explosive technology, expanding its implementation into both combat zones and civil environments. That means no explosive shrapnel or missed shotgun pellets hitting innocent civilians. The capture-vs-destroy design means that a drone downed via a net retains its forensic integrity, allowing operators to gain valuable data and intelligence from the preserved drone.

While no defense is impenetrable, the net-launcher offers a simple yet innovative approach to C-UAS, and a more adaptable option as opposed to shotguns. The design of the net pods allows for fast and reliable integration across many launching applications, from personal protection launchers to aerial interception via drones outfitted with net pods. On top of that, if the goal is to intercept a drone without creating additional risks to personnel or surrounding areas, the non-lethal interception technology has a clear advantage. These characteristics also align with modern safety doctrines and regulations, giving users operational influence in both military and civilian environments.

Counter-UAS is about control, not chaos. For your last layer of defense, precision and safety are the true measures of success.
