The V-BAT series aircraft is the only operationally deployed single-engine ducted fan vertical takeoff and land (VTOL) UAS that can launch and recover from a hover and fly on wing in horizontal flight. With more than five years of persistent operational experience at sea, U.S. and international customers view the V-BAT as a flexible platform capable of performing Group 2 to Group 5 UAS missions and beyond. Ducted-fan technology enables industry leading max-takeoff weight to payload weight ratio. V-BAT's duct increases thrust by 80%+ at equivalent engine power, enabling take-off and landing with a single power plant and achieving unmatched payload mass fraction. It can fly for a half day or stop and hover for hours on end.
