When a modified FPV drone sweeps across an airport runway at 150 km/h, when a fiber-optic-video “black flight” racing drone circles over a chemical park on a reconnaissance run, when an unidentified aircraft suddenly appears above a concert grandstand — traditional “soft-kill” countermeasures are failing across the board. In 2025, China’s police drone market reached RMB 8.64 billion, and the public-safety drone market exceeded RMB 12.86 billion. At the same time, the number of low-altitude security incidents caused by FPV drones has climbed in step. High-speed FPV interceptor drones and hard-kill equipment are shifting from “optional” to “mandatory.”

01 Industry Pain Points: Low-Altitude Security Is Entering the “Hard-Kill” Era

In 2026, low-altitude security threats are no longer as simple as “tourist aerial photography.” They are high-frequency risks spanning airports, energy facilities, sporting events, borders, and corrections:

Modified FPV drones intruding into airport clear zones, forcing flights to divert or be delayed;

Racing drones circling chemical plants and power stations to film processes and data, creating espionage risk;

Unidentified aircraft appearing above concert and stadium grandstands, putting crowd safety under pressure;

GPS-disabled modified drones, fiber-optic FPVs, pre-programmed autonomous-route drones, and low-altitude swarms are spreading into civilian scenarios.

Why do traditional countermeasures fail? Jamming guns cannot catch high-speed targets and are essentially useless against autonomously flying drones; net-capture drones lack the speed to stop modified FPVs; laser weapons degrade in rain, fog, and dust, and are costly to deploy; and large-area air-defense equipment offers extremely poor cost-effectiveness against low, slow, and small targets. The underlying logic of low-altitude defense must shift from “soft deterrence” to “hard kill” — and the high-speed FPV interceptor drone is precisely the core vehicle for this “last line of defense.”

02 Who We Are: Foshan Nullspace Innovation Technology

From “second-trigger individual interception” to “multi-aircraft coordination covering a 60 km depth,” the LKHB series delivers seamless layered protection on a single technology stack.

04 Core Technology Breakdown: Five In-House Capabilities

The technical bar for high-speed FPV interceptor drones is far higher than that of ordinary consumer racing drones. The core barriers of the LKHB series are reflected at five levels:

In-house high-speed flight controller: not a modified open-source flight controller, but deeply optimized for high-G maneuvering above 350 km/h, strong wind disturbance, and jamming suppression;

Dual-sensor AI composite guidance: a 640-pixel uncooled infrared thermal imager plus a 1200TVL visible-light camera, capable of locking onto targets as small as 3×3 pixels, with target recognition accuracy ≥85% and a false-alarm rate <5%; resistant to occlusion, vibration, and decoys, with terminal impact accuracy at the 0.3-meter level;

Anti-jamming data link: 915 MHz / 2.4 GHz / 5.8 GHz multi-band redundancy, maintaining stable communications in strong electromagnetic environments such as industrial zones, substations, and borders;

Pure kinetic hard kill: no explosive warhead, no fragmentation, no risk of secondary deflagration; after interception, damaged components can be replaced and the aircraft reused, giving a long-term cost of ownership significantly better than one-shot net-capture projectiles or missiles;

System-level closed loop: radar/electro-optical detection → AI classification (distinguishing birds, kites, consumer drones, and FPV types) → threat assessment on the command platform → interceptor launch → tracking and impact → 4K video, geotagged timestamps, RTSP streams, and full event archiving.

05 Countermeasure Comparison: Why High-Speed Kinetic Interception Is the “Endgame”

Put the mainstream counter-UAS methods in a single table, and the conclusion becomes very clear:

Countermeasure	Vs. Autonomous FPV	Vs. Fiber-Optic FPV	Urban Compliance	Cost-Effectiveness	Operational Deployment
Jamming gun	Poor	Ineffective	Spectrum-control risk	Medium	Deterrence only
Navigation spoofing	Poor	Ineffective	High compliance risk	Medium	Soft kill
Net capture	Poor	Poor	Acceptable	Low	Cannot catch high-speed drones
Laser hard kill	Good	Good	Heavily weather-dependent	High system cost	Suited to fixed key sites
High-power microwave	Good	Good	Electronic collateral damage	Medium	Difficult to deploy in urban areas
High-speed kinetic interception (LKHB)	Good	Good	No explosives, minimal collateral	High	Individual, vehicle-mounted, or hangar

The conclusion is straightforward: soft-kill methods are the first layer of deterrence, while high-speed kinetic hard kill is the fallback engagement capability. Especially against fiber-optic FPVs and pre-programmed autonomous drones that do not depend on a remote-control link, only a high-speed FPV interceptor drone that physically locks onto the target itself can truly complete the “shoot-down.”

07 Benchmark Cases

Civil airport clear zones: radar detects an FPV target → threat assessment on the command platform → the LKHB series executes a hard kill, with video records across the entire process for after-action traceability;

Energy and chemical sites: 24/7 unattended defense for power plants, substations, and oil and gas facilities, greatly reducing the staffing burden of manual watchkeeping;

Major sporting events and concerts: portable deployment quickly covers grandstands, stages, and spectator areas;

Border areas: long-endurance blended-wing platforms conduct deep patrols and engagements against cross-border modified drones;

Industrial parks and correctional facilities: fixed hangar deployment enabling 24/7 automatic alert-standby defense.

08 Frequently Asked Questions (FAQ)

Q1: Can it counter fiber-optic FPVs and pre-programmed autonomous drones?

A1: Yes. The LKHB series relies on electro-optical and infrared AI to lock onto the physical target itself, independent of the control link, and is equally effective against fiber-optic FPVs and autonomous-route drones.

Q2: What advantages does hard kill have over jamming guns?

A2: Jamming may fail against autonomous drones that do not rely on a link; hard kill achieves a genuine “shoot-down” through pursuit, lock-on, and physical impact.

Q3: Will debris falling after interception injure people?

A3: Interception missions are typically executed in safe airspace after the target is detected; we work with customers to design interception flight paths and debris descent control protocols.

Q4: Is the top speed of 460 km/h an exaggeration?

A4: The LKHB-1.5 has a measured flight speed of 350 km/h; the 10-inch blended-wing and high-performance 7-inch models reach peak speeds of 390–460 km/h, outperforming the vast majority of modified civilian FPVs on the market.

Q5: Can it be integrated with existing radar, electro-optical, and command platforms?

A5: Yes. Standard interfaces and APIs are provided so it can be integrated into existing security architectures as a hard-kill execution module.

Q6: Is on-site testing supported before purchase?

A6: Yes — including factory visits in Foshan, hardware demonstrations, live interception tests, operator training, and after-sales maintenance.
