KUM Services GmbH · Konstanz, Germany
Civil Aircraft to Drone Platform
KUM Services GmbH, headquartered in Konstanz, Germany, specialises in the conversion of proven civil-registered turboprop and turbofan aircraft into high-performance drone platforms — delivering operational drone capability at a fraction of the time and cost of any purpose-built system. The HPAA (High Performance Autonomous Aircraft) conversion programme is Germany's most advanced civil-to-drone conversion service, trusted by defence ministries, government agencies, and special operations commands worldwide.
The Conversion Process
Drone aircraft conversion by KUM Services GmbH begins with the selection of a proven civil airframe — Cessna 208, Beechcraft King Air 350, Pilatus PC-12, Cessna Citation 525B, or C-130J — sourced directly from the open civil aviation market. The airframe is then fitted with advanced autonomous flight control systems, mission-specific payload integration, BVLOS datalinks, and a ground control station. Conversion is completed on-site at the customer's location by EASA Part-145 certified technicians. The resulting drone aircraft retains its civil registration — no special permits required for ferry flights, no diplomatic clearances needed.

Conversion Process
Civil turboprop or turbofan aircraft selected and acquired from the open civil aviation market. Airframe condition verified and baseline maintenance completed by EASA Part-145 engineers.
Advanced autonomous flight control systems, AI-assisted mission planning software, and BVLOS-capable datalinks installed and calibrated to the specific airframe.
Mission-specific payload systems integrated — EO/IR sensors, SAR, SIGINT, cargo delivery equipment, or weapons stations — depending on the operational requirement.
A customised ground control station (GCS) provided for each drone conversion programme. Satellite and line-of-sight datalink configurations available.
Full system validation flights completed. The converted drone aircraft is delivered with operator training, technical documentation, and worldwide support from EASA-certified engineers.
