Skydweller Aero, a U.S.-Spanish aerospace company, has successfully completed a series of uncrewed test flights of its solar-powered drone, the “Skydweller,” over the Gulf of Mexico. The drone, capable of flying continuously using solar energy, is designed to perform long-duration missions and could revolutionize surveillance operations. The longest test flight during the recent campaign lasted 22.5 hours, while another lasted 16 hours, with both departing from Stennis International Airport in Mississippi.
The Skydweller aircraft, built from lightweight carbon fiber, has an impressive 236-foot wingspan, larger than a Boeing 747, yet weighs only 5,620 pounds. It operates entirely on solar power, collecting energy through 17,000 solar cells during daylight hours and storing it in batteries to sustain flight at night. The aircraft is designed to fly patrol missions for weeks at a time, with plans for continuous missions that could last months.
The test flights are part of a broader collaboration with the U.S. Navy, which awarded Skydweller Aero a $5 million contract in 2021 to evaluate the drone’s potential for autonomous maritime patrol missions. The drone could be used for a variety of tasks, including monitoring airspace, detecting illegal fishing or drug smuggling operations, and tracking wildlife migrations. Skydweller CEO Robert Miller highlighted the potential of the technology, calling the tests “a new era in autonomous aviation.”
Skydweller’s success builds on previous solar-powered flight projects, benefiting from expertise gained from Solar Impulse, a manned aircraft that flew around the world in 2016. The company aims to position Skydweller as a reliable platform for military and commercial operations, filling gaps left by earlier failed solar-powered aviation projects from companies like Google and Facebook.
Next steps in the project will focus on integrating surveillance payloads and expanding flight durations, with the ultimate goal of developing a fleet capable of months-long missions. Skydweller Aero plans to continue testing at Stennis International, leveraging the Gulf’s strategic location for monitoring maritime activities.
The drone’s potential for zero-emission, cost-effective surveillance operations has attracted significant interest, and with ongoing development, Skydweller Aero hopes to push the boundaries of solar-powered flight further in the coming years.
