The Leviathan™ is a fully autonomous small unmanned aircraft system (sUAS) with an industry-leading payload capacity and endurance. With an open-architecture flight control system, spacious payload bay, and included GCS software, Leviathan is the premier platform for developing sensors, data processing and autonomy technology. These open-architecture elements support 3rd party payload and autonomy development.

The Leviathan is the smallest sUAS on the market that is hand-launchable with both beyond-line-of-sight (BLOS) communications and structurally-integrated air sampling hardware. The aircraft has an industry-leading hand-launch maximum takeoff weight and payload volume, reducing the miniaturization requirements for low-TRL sensors. Leviathan supports catapult-launch and has a short development path to high-altitude deployment.
