One fused air picture for the sites you must protect.
For airports, critical infrastructure, bases and forces: detect, understand and decide against low-altitude drones — using the sensors and effectors you already have alongside ours, with accountable, human-authorised control and a dual-use core.
Dual-use: defence and civilian.
Airports
Protect approach and perimeter airspace; keep operations running.
Critical infrastructure
Energy and ports: persistent watch over fixed assets.
Military bases
Force protection for fixed installations.
Borders
Wide-area awareness along a line.
Mobile / convoy escort
The layer moves with the force; forward-deployed.
Helipads & hospitals
Safe approach and departure for rescue and air-ambulance helicopters — in forest and city.
How the layer stands up on site.
Pick a site type to see an illustrative setup. Brass-blue markers are VAERN systems; grey are second/third-party sensors and partner effectors; red is the threat picture. Click a marker or a row to highlight.

Illustrative setups — composition and placement are fixed after a site survey. Sensor packages can be VAERN's own or second/third-party — open by design.
Fixed, mobile and interoperable.
Deploy at fixed sites or on the move. A modular sensor mesh scales with the task and takes in what is already on site: your existing sensors and C2, third-party radar, RF or cameras, and the partner effectors you already operate. Sensor packages can be VAERN's own or second/third-party — VAERN sensors are one option, not a requirement. Open by design, vendor-independent.
- Fixed sites and mobile.
- Modular sensor mesh.
- Integrates with existing sensors, C2 and partner effectors.
- Open / interoperable — no vendor lock-in.
Accountability, built in — for buyers.
- One fused air picture — from every sensor, ours or yours.
- Explainable, auditable classification.
- Human authorisation for every consequential decision (accountability & ROE).
- Dual-use core.
- European supply chain (sovereignty).
- Partner-effector flexibility.
- Dynamic deployment & architecture — no vendor lock-in; integrates what you already own.
The landscape — and our difference.
The counter-UAS landscape spans primes (Elbit, Leonardo, Hensoldt, Lockheed Martin/L3Harris, Northrop Grumman, Raytheon, Rafael), sensor specialists (DroneShield, Dedrone, MyDefence), software and autonomy players (Anduril), and Danish names (Weibel, Terma).
What sets VAERN apart is narrow: the dual-use, explainable decision layer with a person in the loop — open to any vendor's sensors, fixed or forward, built on a European supply chain by design.
Channels we build toward.
