As small unmanned aircraft become cheaper, faster, and more autonomous, physical netting has emerged as a dependable layer in counter-drone strategy. Where radio-frequency detection and jamming systems struggle against autonomous or fiber-optic-guided drones, a properly engineered net works passively, around the clock, with no spectrum coordination required. The result is a containment solution that protects people, equipment, and sensitive airspace, whether the goal is keeping research drones safe, hardening a defense installation, or shielding an industrial site.
Engineered Netting Systems for Unmanned Aircraft Testing, Training, Research & Security
León de Oro USA manufactures custom UAS / UAV containment systems for military, civil, commercial, research, and institutional applications. Our systems help create controlled flight environments for UAV testing, pilot training, research programs, restricted-area protection, public demonstrations, and facility safety.
León de Oro USA does not approach UAS / UAV containment as a one-size-fits-all netting product. Each system can be configured around the aircraft, operating environment, enclosure size, safety objective, and performance requirements of the project.
Material options range from lightweight containment netting for controlled training, research, and demonstration environments to advanced high-performance fiber constructions for demanding applications. Depending on the project, systems may incorporate polypropylene, polyester, Dynoro® UHMWPE-based netting, Kevlar® / aramid options, or other specialized materials.
Dynoro® is León de Oro’s proprietary UHMWPE-based netting option for projects requiring a lightweight, high-strength containment material. It is suited for applications where strength-to-weight performance, low stretch, and specialized system design are important.
Mesh opening, cord diameter, border construction, attachment method, and hardware interface can be specified to suit the application. This allows León de Oro USA to support a wide range of UAS / UAV environments, from indoor university labs and pilot training areas to civil infrastructure, defense, industrial, and high-security applications.
Military & Defense
Anti-drone netting has become one of the fastest-growing applications in physical security, and for good reason. Small drones now pose a credible threat to installations, vehicles, and personnel, and electronic countermeasures alone cannot reliably stop every threat. Physical netting closes that gap. León de Oro USA counter-drone nets are engineered to intercept and contain small unmanned aircraft, providing a passive, always-on layer that complements detection and jamming systems.
- Counter-UAS Perimeter Netting – Engineered barriers that physically block small drones from entering protected airspace, defending against surveillance and payload-carrying threats.
- Forward Operating Bases & Installation Perimeters – Rapidly deployable and permanent netting systems that harden the boundaries of bases, depots, and command facilities.
- Training Ranges & Test Facilities – Containment for live-fire ranges and drone test environments where controlling flight boundaries is essential.
- Defense Research & Development – Secure flight enclosures for defense labs and contractors developing and evaluating unmanned systems.
- Vehicle & Equipment Protection – Overhead drape nets and shrouds that shield parked vehicles, staging areas, and critical equipment from drone-dropped or first-person-view threats.
Universities & Research
Research drones are expensive, and the work they support, autonomy development, sensor testing, environmental monitoring, is often impossible to repeat under identical conditions. León de Oro USA drone nets give research teams a controlled environment to fly, test, and recover their equipment without risking damage or losing data.
- University Drone Programs – Custom flight cage netting for engineering departments, aerospace labs, and student competitions, supporting both instruction and sponsored research.
- Autonomy & Algorithm Testing – Enclosed indoor and outdoor flight spaces where teams can develop navigation, swarming, and AI flight behavior within a contained area.
- Prototype Validation – Catch netting that protects high-value prototypes from crash damage during early-stage flight testing.
- Environmental & Marine Research – Drone containment systems for facilities running water-based operations, including configurations that support retrieval of equipment from the water.
- National & Aerospace Labs – Large-format containment for institutions running sustained flight research across multiple drone classes.
Industrial
For industrial and commercial operators, drones represent both a security risk and a safety hazard. León de Oro USA industrial drone netting protects critical infrastructure, restricts access to controlled airspace, and contains drone activity across a wide range of facilities.
- Critical Infrastructure & Utilities – Protection for substations, telecommunications sites, water treatment plants, and data centers where airspace intrusion is a security concern.
- Energy & Petrochemical – Drone containment for refineries, oil and gas operations, nuclear facilities, and LNG terminals where unauthorized overflight carries serious risk.
- Corporate Campuses & Manufacturing – Perimeter and overhead netting that guards proprietary operations, research areas, and high-value facilities against drone surveillance.
- Logistics & Warehousing – Containment systems for distribution centers and sites testing drone-based inventory or delivery operations.
- Correctional & Secure Facilities – Netting that prevents contraband delivery and unauthorized surveillance at detention centers and other controlled sites.
- Stadiums & Event Venues – Airspace control for arenas, public gatherings, and events where drone activity must be restricted for safety and security.
Why Physical Netting
Counter-drone strategy increasingly relies on layered defense, and physical netting fills gaps that electronic systems cannot.
- It works against autonomous and fiber-optic drones – Jamming disrupts the radio link between a drone and its operator, but autonomous drones flying preprogrammed routes, and fiber-optic-guided drones with no radio link at all, are unaffected. A net stops them physically.
- It runs passively, around the clock – Once installed, netting requires no power, no operator, and no radio spectrum coordination. It protects continuously.
- It is cost-effective – Compared with kinetic interception or active electronic systems, netting delivers reliable containment at a fraction of the operating cost.
- It is predictable – A net does not misidentify targets or require a decision in the moment. It simply contains.
