It might look like a helicopter, and act like a helicopter, and perform tasks typically associated with a helicopter, but it isn’t a helicopter. And that’s exactly the point.

Showcased in a big way at XPONENTIAL 2025 at the Unmanned Aerospace booth, the GH-4 combines the long-flight endurance of a fixed-wing UAV with the hovering capability of a helicopter. It features patented Automatic Pitch System (APS) technology, allowing it to take off and hover like a helicopter while consuming 40% less energy in forward flight. This patented technology is the key ingredient that makes these capabilities possible.

With a hover time of 30 minutes, 140 NM range and total flight time of four hours, the GH-4 is well suited to support critical delivery and inspection across hard-to-reach locations. It is also designed to evolve into larger rotorcraft, making it adaptable for both military and commercial operations. The hydrogen fuel-powered engine utilizes fuel cells and hybrid booster batteries for these sorts of long-endurance missions.

The rack-release system allows cargo to be carried outside the fuselage and be released on demand. Applications that range from ship-to-shore delivery to aerial inspections to long-distance missions that support offshore oil rigs are just the beginning of where and how this technology can be used.

“The GH-4 has nothing to do with helicopters but can do anything that a helicopter does,” said Gad Shaanan, CEO & Founder at Unmanned Aerospace. “It represents a whole new way to approach long-distance operations and can scale up however needed, so we’re excited to explore the many different ways that this clean energy option can make a difference for anyone looking to reduce costs and save time.”
