Drone boat picked up downed US Army helicopter pilots—a first for sea rescues

9 June 2026 at 16:44

A drone boat picked up two US Army pilots from waters near the Strait of Hormuz after their helicopter gunship went down, US military officials said. The incident apparently represents the first time the US military has used a drone for such a rescue mission at sea.

The two crew members from the US Army AH-64 Apache were “rescued by American forces” at 7:33 pm US Eastern Time after their helicopter went down off the coast of Oman on June 8, according to a US Central Command press release. That press release mentioned support from US Navy units including the US 5th Fleet’s Task Force 59, which is charged with integrating uncrewed aerial, surface, and underwater vehicles, alongside AI, into 5th Fleet maritime operations.

Anonymous US military officials initially told CBS News that the Apache air crew was rescued by an uncrewed surface drone operated by Task Force 59 from the US Fifth Fleet in Bahrain. The officials also described the incident as the first time the military had used a drone to rescue people from the water.

For David and Ruth Hudspeth, the process of turning their 1950s brick veneer house in Melbourne’s eastern suburbs into a cosy, efficient and fully electric home took several years.

They started with insulation in the ceiling and replacing an old and “pretty dangerous” gas heater. They swapped their leaky hot water system for a heat pump, and built a roof over the outdoor deck for shade and extra solar panels, later adding an electric car and a home battery into the mix.

Used Waymo robotaxi batteries become backup storage for power grids

4 June 2026 at 12:00

Thousands of electric vehicles in Waymo’s autonomous robotaxi fleet may eventually give up their used batteries for a very different purpose—contributing up to hundreds of megawatt-hours of stationary energy storage to local power grids.

That prospect comes from a “strategic supply agreement” announced by Waymo and B2U Storage Solutions on June 4. B2U has been repurposing thousands of used batteries from various electric vehicles by installing them in large stationary energy storage projects. Such energy storage facilities can capture excess renewable energy during low demand periods and release such energy when local power grids are experiencing peak demand periods.

“Our business is getting the full residual value out of electric vehicle batteries after they're no longer suitable for automotive use,” Freeman Hall, CEO of B2U Storage Solution, told Ars. “Waymo puts a lot of miles on EVs and their model is expanding rapidly, and so we're just very pleased and honored to be able to work with them.”
