Wildfire systems beat 10-minute detection target in Alaska tests

Three teams testing autonomous wildfire technology in Alaska each detected a high-risk fire in under 10 minutes, a promising step towards giving firefighters earlier warning while a blaze may still be easier to control.

The June 2026 trials, part of the XPRIZE Wildfire competition, challenged teams to find and completely extinguish a fire within 10 minutes of ignition across 1,000 square kilometres of rural terrain, while leaving decoy fires alone. Finding the fire proved more successful than stopping it: two teams deployed drones that attempted suppression, but none fully extinguished the blaze. The grand prize for autonomous response went unclaimed.

The systems offered different ways to spot trouble early. Anduril Industries used a tower with heat-sensing equipment and AI to identify possible ignitions, then sent surveillance and fire-suppression drones. Dryad Networks combined 170 solar-powered ground sensors that detect gases from smouldering fires with drones to locate and tackle the blaze.

XPRIZE recognised these and other advances with US$4.55 million in awards across its autonomous response and satellite-based detection tracks. The competition now moves into a planned 12- to 15-month follow-up phase to help promising technologies reach practical deployment. The tests demonstrated faster detection, while making clear that reliably stopping a fire without human intervention still needs work.
