A solar-powered drone has actually been lost at sea after a record-breaking flight lasting 8 days in between late April and early May. The crash likewise marks the unforeseen death of the pioneering airplane Solar Impulse 2, which formerly carried out the world’s very first solar-powered crossings of the Atlantic and Pacific oceans before ending up being an uncrewed test platform for United States military objectives.

The carbon-fiber airplane might carry out such tasks of aerial endurance while running entirely on renewable resource and batteries due to the fact that of a 236-foot (72-meter) wingspan– equivalent to a Boeing 747 jumbo jet’s wings– covered with more than 17,000 solar batteries. The business Skydweller Aero bought and customized the initial Solar Impulse 2 airplane to end up being a test platform for “continuous uncrewed flight” with the ability of bring approximately 800 pounds (363 kgs) of payload.

Skydweller Aero was carrying out test flights for maritime patrol objective circumstances with the United States military, and the business likewise holds agreements with the Navy and Air Force.

In the Navy

After leaving from Stennis International Airport in Mississippi, the Skydweller drone flew to sign up with the United States Navy’s yearly Fleet Experimentation (FLEX) works out near Florida’s Key West, according to a Skydweller Aero article. The Navy’s news release explains the FLEX 2026 occasion as screening AI and drone innovations for maritime patrols “in the battle versus global the mob.”

As part of the occasion, the drone utilized radar in addition to visual and thermal imaging to observe targets on the water throughout 4 days of constant flight, according to Skydweller Aero. It likewise served as a flying interactions center for Navy airplane and warships while supporting AIS transponder-based tracking of ships in the location.

The Navy likewise highlighted the presentation of a “advanced kill chain” which integrated business drones with crewed United States military helicopters and the Freedom-variant littoral fight ship USS WichitaTogether, such possessions “effectively discovered, repaired, tracked, and targeted a recorded drug boat” in a situation leading up to “kinetic engagements damaging a number of recorded drug boats,” according to the Navy’s news release.

It is uncertain what function the Skydweller drone might have played in the workout’s drug boat situation. Ars has actually connected to the United States Navy for remark.

The marine workout comes as United States Southern Command (SOUTHCOM) has actually carried out lots of “deadly kinetic strikes” versus declared drug boats running in the Caribbean and Pacific given that September 2025. The deadly strikes have actually eliminated around 194 individuals to date, according to the not-for-profit think tank InSight Crime– and legal and human rights specialists have stated the strikes break both domestic and global law.

The drone ultimately placed itself south of Cuba and north of the Cayman Islands while suffering a duration of bad weather condition.

Last location

By the night of May 3, the drone was experiencing extreme climate condition that consisted of “severe vertical air mass irregularity going beyond 10 times common climb and descent rates,” Skydweller Aero composed. The business highlighted that all airplane systems were small throughout the flight– however an absence of energy reserves to handle the severe weather condition ultimately lowered the drone.
