Vesper is an American-made, NDAA-compliant and Blue UAS-cleared quadcopter UAS (unmanned aerial system) designed to provide rapidly deployable aerial reconnaissance day or night. The versatile drone platform offers two interchangeable rotor assemblies: a shrouded set for operating indoors or near people, and a reconnaissance set for enhanced speed, endurance and stealth.
The aircraft incorporates a field-swappable, three-axis stabilised gimbal featuring dual 4K EO sensors and a choice of 320 × 240 or 640 × 480 LWIR thermal imagers, making it well suited to mission-critical ISR (intelligence, surveillance and reconnaissance) and civilian applications such as inspection. Vesper packs into a compact IP68-rated hard-shell field case with a combined weight of just 1 kg and can be deployed within 90 seconds.
Designed for sensitive military and government applications, Vesper features AES-256 encryption on all communications and bonded construction to prevent tampering.
