What we doSpecial Missions
Built for jobs that don't come with a manual.
Surveillance, survey and other unusual work, with aircraft modified in-house.
The short version
We take a Twin Otter, integrate the mission system in our own hangar, certify it, crew it, maintain it and fly it, for as long as the contract runs. One company, one set of approvals, one phone number.

Proof
Case in point: Denmark
In April 2023 the Danish Ministry of Defence awarded Zimex an eight-year lease for two DHC-6-300 surveillance aircraft. We modified them at Altenrhein and integrated Airborne Technologies' Airborne LINX system: sensors plus an operator workstation. The aircraft entered service in 2024 as Hugin and Munin. In their first year they flew about 1,000 hours on 150 missions for the police, defence, Frontex and NATO's Baltic Sentry. A third aircraft, Sleipnir, was announced in September 2026.

What we can build
Maritime and border surveillance
Survey and mapping
Parachute operations
Sensor and mission-system integration
Special cabins, from medical evacuation to operator workstations
Unusual is normal.
We've been modifying aircraft for odd jobs since the 1980s, when a Zimex twin turboprop carried a purpose-built dispenser that released parasitic wasps over the cassava fields of Africa. Surveillance is one of the less unusual things we've been asked to do.

Questions
Which aircraft do you modify for special missions?
The Twin Otter. For the Danish Home Guard we modified DHC-6-300s at Altenrhein and integrated Airborne Technologies' Airborne LINX system: sensors plus an operator workstation.
Do you only modify the aircraft, or fly it as well?
Both. We integrate the mission system in our own hangar, certify the aircraft, crew it, maintain it and fly it, for as long as the contract runs.
Who looks after airworthiness during the contract?
We do. Maintenance and CAMO stay in-house, under the same set of approvals as the flying: EASA Part-145 CH.145.0230 and Part-CAMO CH.CAMO.1025.
How long can a contract run?
As long as you need. The Danish Home Guard lease, signed in 2023, runs for eight years.
What else can you build besides surveillance aircraft?
Survey and mapping aircraft, parachute operations, sensor and mission-system integration, and special cabins, from medical evacuation to operator workstations.
