The 1,000-kg prototype remained airborne for 16 hours, covering 2,400 km and demonstrating excellent fuel efficiency and aerodynamic performance.<br /><br />The U.S. company with Belarusian roots, UAVOS, recently announced the successful test results of its new medium-altitude, long-endurance (MALE) unmanned aerial vehicle (UAV), the S1V300.<br /><br />During a recent test flight, the 1,000-kg UAV stayed aloft for about 16 hours, covering approximately 2,400 km — a significant milestone that highlights the platform’s potential for long-range operations.<br /><br />According to UAVOS founder and CEO Alexey Stratsilatov, the successful results stem from a series of technical improvements that directly enhanced flight efficiency and endurance. These include a large-span wing with aerodynamic tips, improved wing mechanization, a lightweight composite landing gear, retractable air intakes, and a Y-shaped tail.<br /><br />Cruising at a speed of 130 km/h, the S1V300 consumes only 10 liters of fuel per hour. UAVOS reports that the system is capable of flying for more than 40 hours while carrying a payload of 30 to 40 kg.<br /><br />The platform is offered for both civilian and military applications. In the commercial sector, it can be used for environmental monitoring, border security, infrastructure inspection, and precision agriculture. In defense operations, the S1V300 is suitable for intelligence, surveillance, and reconnaissance (ISR) missions.<br /><br />The new system strengthens UAVOS’s portfolio of MALE (Medium Altitude Long Endurance) solutions, consolidating the company’s position as one of the leading independent developers of unmanned aviation technologies in the global market.<br /><br />Source and images: UAVOS.
