Most drones are significantly smaller than crewed aircraft and have shorter flight ranges, meaning they cannot replace large airtankers in delivering massive payloads of water or other fire\-suppressing payloads to remote wildfires\. But companies and fire agencies—along with organizers of the $11 million XPRIZE competition—are testing whether drones can help firefighting crews respond more quickly to small fires and put them out before they become more destructive\. The California Department of Forestry and Fire Protection, also known as CAL FIRE, ran its own field test involving five autonomous drones that worked together to deploy between 500 and 1,000 gallons of foam combined for suppressing fires on July 15, according to the[TV station KPMH](https://kmph.com/news/local/calfire-tests-autonomous-drones-to-bolster-wildfire-operations-in-california)\. The demonstration was organized with the help of the nonprofit FireWERX and the California\-based[company Seneca](https://seneca.com/), which is making the drones commercially available starting in 2026\. Each of Seneca’s Argo\-1 drones can carry about 100 pounds of water or fire retardant while working together in swarms of four to six drones\. Once a human operator uploads a GPS waypoint, the autonomous drones fly toward their target and use onboard sensors to spot the heat signature of a fire,[HeliOps Magazine](https://www.heliopsmag.com/airattack/articles/firefighting-drones-move-to-the-next-generation/)reported\. The drones then find the best hovering altitude before each lining up to spray the fire, one after the other\. The fully loaded drones are limited to a round trip of 10 miles while flying at about 30 miles per hour on average, which means they would ideally need to be prepositioned in fire\-prone areas or first transported by ground vehicle\. But each drone can fit in the back of a pickup truck with the tailgate down, and two people can even manually carry the empty drones\.
