As wildfires plague the United States nearly year-round, a new tool is being tested to help combat these blazes: firefighting drones. Companies like Seneca and Dryad Networks are developing autonomous systems capable of spraying water and fire retardants, with some already demonstrating their capabilities in California and Alaska this summer.
The challenge facing firefighters has grown significantly due to climate change, transforming wildfire season into a prolonged risk for much of the country. Traditional crewed aircraft have limitations, including shorter flight ranges and higher costs compared to drones. However, these smaller drones can work together in swarms to suppress fires more quickly and efficiently.
Seneca's Argo-1 Drones: A Rapid-Response Tool?
Seneca’s Argo-1 drones are designed for rapid-response firefighting. Each drone can carry about 100 pounds of water or fire retardant, with a maximum round trip range of 10 miles at an average speed of 30 miles per hour. The drones use onboard sensors to spot the heat signature of a fire and then line up to spray it one after the other.
In a demonstration organized by the nonprofit FireWERX and Seneca, five autonomous drones worked together to deploy between 500 and 1,000 gallons of foam for suppressing fires on July 15. The goal is to enable firefighters to refill a returning drone’s payload and swap in a fresh battery so that it’s ready to fly again in two minutes.
XPRIZE Competition Pushes the Boundaries of Firefighting Drones
The $11 million XPRIZE competition has been testing various firefighting drone systems, including Dryad Networks’ Silvaguard autonomous system. In finals testing just outside of Fairbanks, Alaska in June 2026, Silvaguard worked with Dryad’s Silvanet wildfire detection network to autonomously detect and suppress a wildfire within the competition’s 1,000 square kilometer test area.
Dryad’s detection system consists of solar-powered sensors attached to trees that are designed to detect smoke from smoldering fires. When a sensor triggers an alarm via a wireless mesh network, a prepositioned Silvaguard observation drone launches to confirm and geolocate the fire using infrared and optical imaging sensors.
Early Adopters and Future Prospects
The Aspen Fire Protection District in Colorado has already committed to a $5 million contract for deploying five of Seneca’s drones over five years. CAL FIRE, which operates the world’s largest aerial firefighting fleet with more than 70 crewed fixed-wing aircraft and helicopters, has not signed up any firefighting drones just yet but represents another large potential customer.
The ultimate test for these drone systems will come if fire agencies deploy them during the lengthening wildfire season. If successful, they could provide a valuable tool in the fight against wildfires, helping to save lives and property while reducing the environmental impact of traditional firefighting methods.
