Koios S2 class VTOL UAS for strategic ISR operations
Koios

The Koios S2 class UAS is a medium-sized, VTOL platform engineered for both defence and civil ISR missions. Designed for rapid deployment in austere environments, it combines strategic surveillance reach with a compact operational footprint. Fully runway-independent, Koios employs eight brushless electric motors to achieve vertical lift with redundant power architecture, ensuring operational continuity in remote or unprepared zones.

Payload-agnostic and field-proven across diverse mission sets, Koios accommodates up to 7 kg including fuel and can be rapidly deployed by a two-person crew. The system disassembles into two transportable cases and can be assembled, checked, and airborne in under ten minutes.
