The Unmanned Aircraft Systems Test Directorate piloted the helicopter fueled with a combination of JP-5 aviation fuel and plant-based camelina. The biofuel blend reduces carbon dioxide output by 75 percent when compared to conventional aviation fuel. The MQ-8B Fire Scout Vertical Take-Off and Landing Tactical Unmanned Aerial Vehicle provides critical situational awareness, intelligence, surveillance, reconnaissance (ISR), and targeting data to the forward deployed warfighter."
