Solar drone with Boeing 747 wingspan promises month-long flights

The article discusses a groundbreaking solar-powered drone developed through a partnership between French defense electronics company Thales and US aerospace startup Skydweller Aero. This unmanned aerial system, named MAPS (Medium-Altitude Pseudo-Satellite), features a wingspan larger than a Boeing 747 and can carry payloads up to 881 pounds (400 kg). Designed for persistent, long-duration flights lasting weeks to a month, the drone operates at medium altitudes without carbon emissions, enabling near-continuous surveillance of vast maritime areas such as Exclusive Economic Zones, shipping lanes, and contested waters. A key innovation is the integration of Thales’ AirMaster S radar, an AI-enabled, lightweight sensor suite with Active Electronically Scanned Array (AESA) technology, which provides rapid situational awareness across air, land, and sea domains. The radar’s AI-driven data processing allows onboard target classification, reducing data transmission needs and enhancing bandwidth efficiency critical for extended autonomous missions. This combination creates a fully autonomous
