Payload Agnostic
Power Over Tether
Tactically Repositionable

Payload Agnostic

Built for radios, qualified payloads include Silvus, Trellisware, Persistent Systems, L3 Harris, Viasat, goTenna, multiple sensors, cameras, and others.

Power Over Tether

Unlike battery-powered drones, our tethered drones have unmatched power and unlimited flight time for hours, days, and weeks.

Tactical Repositioning

Transporting portable drones is efficient and convenient with quick setup for maximum flexibility in stationary or mobile missions.

Superior Drone Technology

Hoverfly Technologies is a leading national provider of federal defense drones, security drones, and public safety drones. The SPECTRE has unparalleled situational awareness capabilities to the dismounted leader and features a field-swappable open architecture payload bay, providing persistent ISR and extending the communication range by dozens of miles/km. This model provides full auto-piloting when in autonomous flight, precision take-off/landing, and battery backup with auto-landing in the event of power or communication loss. There are no RF signals which ensure secure video and data over tether with our jam-proof design.

In The Field

Our tethered drones are fielded by branches of the Armed Forces and industry partners to provide a mobile ad-hoc network of flying communications or ISR nodes.

Made in the USA

Our drones are proudly designed, built, and supported in the U.S. Hoverfly has been developing the best Unmanned Aerial Vehicles (UAVs) for government, industrial, commercial, and other specialized applications across the globe.

Seamless SDK Integration

Hoverfly’s Software Development Kit (SDK) allows Hoverfly and its sensors to be controlled over various networks or the internet for multiple fused sources in a Common Operating Picture (COP). It also enables seamless integration with existing security and video management systems with libraries for .NET, C++, and more coming soon. Our SDK provides three levels of access to the Hoverfly system: full control, payload-only control, and telemetry monitoring.
