About Reliant
Reliant combines vertical takeoff and landing with more than ten hours of endurance, a 160+ km data-link range, and a compact 10 × 10 metre launch-and-recovery footprint. A two-person team can assemble the aircraft, while a single operator can run missions from remote terrain, vehicles, rooftops, or ships.
Dual hot-swappable payload bays support electro-optical, SAR, SIGINT, electronic-warfare, SATCOM, relay, and navigation-resilience packages. Onboard Jetson Orin compute supports detection and adaptive mission execution, and the July 2026 upgrade introduced hybrid-electric propulsion, payload capacity up to 9 kg, and full MOSAIC UXS integration.
