United States, May 2 -- Sikorsky, a Lockheed Martin company and Rain, a leader in the emerging firetech industry, demonstrated and tested autonomous wildfire suppression techniques on both propane and burning brush piles using Sikorsky's optionally piloted MATRIX flight autonomy system layered with Rain's wildfire suppression planning software. Performed in late April in Southern California, the flight tests familiarized firefighters with the potential of autonomy to help crewed and uncrewed firefighting helicopters find and suppress early-stage wildfires.The autonomous wildfire suppression tests in late April were the first performed by Rain and Sikorsky in California over live fires in wildfire-prone terrain; at 3,300-ft altitude; sometim...
