Integrating innovative energy-efficient stealth technologies, the Stealth Hawk HE-400 marks the direction of covert military operations. Its distinctive airframe design lowers drag and increases lift, hence lowering power demand during longer surveillance operations. Using next-generation lithium-air batteries to drive a complex electric propulsion system, the drone offers an amazing power-to----weight ratio. Further improving its energy economy are advanced heat management systems and regenerative braking technologies, which enable missions up to 72 hours without refuelling.
