VAERN develops the software and assembles the complete system: partner radar, RF and EO/IR sensors, a resilient datalink and the HAMMER operator console — fixed or mobile, for civil sites and defence.
Status: the HAMMER console runs on simulated data today. The physical chain from sensor to response has not yet been built or validated.
VAERN develops the software and assembles the complete counter-drone system — sensors and radios from specialist partners, effectors from authorised partners.
Partner sensors · VAERN integration
Radar, passive RF and EO/IR from specialist partners — or the sensors already on site — designed to feed one picture through VIGIL. SCOUT forward nodes are designed to extend coverage when the unit moves.
Status: integration planned.
VAERN software
NEXUS is the planned datalink between the nodes, and CORE the planned role for fusion and classification. HAMMER, the operator console, exists today as a prototype on simulated data and brings the picture, the operator's decision and the decision record together.

Status: HAMMER is a prototype on simulated data · NEXUS and CORE are planned.
Authorised partners · human approval
STRIKER is designed to connect the operator's decision to partner effectors: nets, interceptors and jammers. The integration is being developed together with partners and is not finished yet.
VAERN does not manufacture effectors. Partners supply them under their own authorisations and only where the law allows. A human authorises every engagement. At civilian sites, VAERN provides the air picture; authorities with a legal mandate carry out any intervention.
HAMMER is the operator console. The current demo uses simulated data and synthetic scenarios; the physical sensor and effector chain has not been validated.
VAERN's role: site survey, system design for your site or unit, and integration of partner hardware and the HAMMER console into one chain. The final configuration follows a site survey.
An unknown track approaches. The first observation starts the illustrated operator workflow.
VIGIL · Sensor observationAn illustrated design goal for one site — not live data or demonstrated performance.
The sensor layer gives the operator the first indication.
Observations from different angles are planned to travel through the same network.
HAMMER shows the track and the basis for its assessment.
The operator assesses the threat and authorises the response in HAMMER.
A partner effector, operated by the force or authority with the legal mandate, activates after authorisation, and the event is logged. The entire sequence illustrates a design goal.
Capture, shoot down or jam — only after a human authorises it. VAERN does not manufacture effectors. Partners supply them under their own authorisations and only where the law allows. A human authorises every engagement. At civilian sites, VAERN provides the air picture; authorities with a legal mandate carry out any intervention.
The sequence above illustrates a design goal — not live data or demonstrated performance. The example layouts show how sensors, console and response route could be placed at different types of site.

Fixed at a refinery, power plant or port, on board a ship, or moving with a unit: the same chain from detection to decision, with sensors and response matched to the site — and to who has the mandate to intervene.
Status: the HAMMER console runs on simulated data today. The physical chain from sensor to response has not yet been built or validated.

Counter-drone for naval vesselsThe sensors, the console and the decision record are the same. What differs is who may intervene.
Airports, energy sites, ports, ships and hospitals: the system is designed to give site security early warning and a decision record. At civilian sites, VAERN provides the air picture; authorities with a legal mandate carry out any intervention.
Typical set-up: radar, RF and EO/IR · HAMMER in the control room · hand-over to the police or, for ships, the coastguard or authority with the mandate.
For bases, mobile units and naval vessels the system is designed to run the full chain, including partner effectors operated by the armed forces or authorities under their own authorisations and only where the law allows.
Capture, shoot down or jam — only after a human authorises it.
Typical set-up: fixed or vehicle-mounted sensors · SCOUT nodes · NEXUS mesh · STRIKER to partner effectors.

Copenhagen Airport (Kastrup)
On the evening of 22 September 2025, air navigation provider Naviair halted all take-offs and landings at Copenhagen Airport after reports of two to three drones nearby. Traffic resumed around 00:30. In June 2026, Copenhagen Police said it could neither demonstrate nor rule out drone activity.

Auvere power station, Ida-Viru County
At 03:43 on 25 March 2026, a drone that entered Estonian airspace from Russia hit a chimney at the Auvere power station near the Russian border. Nobody was hurt. The government said several drones crossed the border that morning during a Ukrainian attack on the Russian port of Ust-Luga.

Esbjerg, Sønderborg and Air Base Skrydstrup
On the night of 24–25 September 2025, police received reports of drones near Esbjerg and Sønderborg airports and Air Base Skrydstrup. The Danish Armed Forces said drones had been observed at several military installations, including Skrydstrup and the army barracks in Holstebro.
