Animal Dynamics is developing a range of unmanned aerial delivery vehicles called Stork, based on powered paraglider wing technology. The current roadmap includes a range of vehicles:

ST 50 capable of carrying 30 kg and ST 150, capable of carrying 100kg. Further vehicles are planned, capable of carrying loads up to 3000kg.


Each system comprises a canopy, a vehicle with landing gear and a power unit. The 50kg vehicle is powered by an electric motor. The larger vehicles are powered by internal combustion engines. Each unit has an autonomous guidance system, comms, and camera. 


  • Short take-off and landing capability

  • Autonomous guidance and navigation in both GPS and GPS-denied environments

  • Stealthy: low noise and radar signature, and can glide silently to target

  • Long endurance, high efficiency, long range ST150 range over 100km; ST1800 over 300km

  • Low cost: the cost of the vehicle per kg delivery capacity is <1/10th of the capital cost of all other delivery systems; running costs are lower still

  • Robust: the canopy is damage tolerant, and the vehicle has a graceful failsoft mode, gliding to a gentle landing in the rare event of catastrophic engine or systems failures

  • The vehicle itself packs down small, and is easy to transport on a standard NATO pallet

  • Vehicle mass between 20% and 30% of the potential payload mass.


Supply Into Hazardous Environments

Stork can be used to supply medical equipment, food, fuel and vehicle parts from a Forward Operating Base (FOB) to front-line users. The vehicle can be loaded up ready for take-off from outside the warehouse or ground vehicle.

Stork models are capable of travelling 1- 300km at 70 km/h to a pre-set GPS location, depending on size (larger vehicles travel a greater distance).
