Drone Services
Drone Services a low-cost way to deliver long-range emergency support for defence, humanitarian aid, research and civil air cargo, where existing infrastructure is poor. In coordination with our network partners, we provide an end-to-end multimodal supply chain from the supplier to the client over air, land, and sea. We specialize in remote site solutions for operations in conflict zones throughout Eastern Europe, Africa, Middle East, and Central Asia.
Drone Operations Platform
The ULTRA drone platform brings together advanced aircraft technology, integrated autopilot systems and mission control software and operational services that draw on best practices from military and civil aviation.
Designed and built to take on a variety of roles across diverse environments, ULTRA drones have completed missions in seven countries on three continents, from isolated communities in North America to reconnaissance and resupply in Ukraine.
With a useful payload of up to 150kg and a range of up to 1,000km, ULTRA drone provides autonomous air cargo drone transport to places where infrastructure is limited and costs are high.
Aircraft that Defies Limits
At the heart of the Windracers ULTRA platform is the ULTRA cargo aircraft, designed explicitly for heavy-lift operations without the hefty price tag. Unlike smaller cargo drones with limited capacity and range, ULTRA is an unmanned aerial vehicle that handles heavy loads across middle-mile distances and for extended endurance.
A rugged fixed-wing build means the ULTRA can master even the harshest weather. It has proven successful in the sub-zero temperatures of Antarctica, as well as the wind and rain of the North Atlantic, and is set to expand operations into Africa soon.
Powered by standard fuel and designed for fast turnaround on the ground, ULTRA is the go-to solution for transporting goods in areas where road infrastructure is poor or non-existent.
Every aspect of ULTRA has been engineered and constructed with high redundancy, ensuring minimal risk of failure so you can rely on it, no matter the circumstances.
