Threod Systems Theia is a fixed-wing military/ISR drone built for organizations that value persistent airborne surveillance more than consumer-style convenience. Based on the supplied data, it stands out for a 24-hour endurance figure, a 75 kg maximum takeoff weight, and a 4.2 m wingspan, putting it firmly in the institutional and defense-oriented UAV category. For readers comparing long-endurance ISR platforms, Theia matters because its published headline numbers suggest a serious fixed-wing system, even though many commercial and payload details are still not publicly confirmed.
