HevenDrones, a leader in hydrogen-powered drone technology, has announced the acquisition of Zepher Flight Labs (ZFL), a move that enhances its modular, long-endurance unmanned aerial systems (UAS) for defense and commercial applications.
The acquisition, announced on April 25, 2025, aims to integrate Zepher's expertise in vertical takeoff and landing (VTOL) drones with HevenDrones' hydrogen fuel cell technology. This synergy is expected to produce drones capable of operating from remote, infrastructure-limited environments, addressing the need for long-range, low-maintenance aerial platforms in military operations.
Bentzion Levinson, CEO of HevenDrones, stated,
"This acquisition strengthens our position in the market and underscores our commitment to providing the most advanced and reliable drone solutions."
Adam Stolz, CEO of Zepher Flight Labs, added,
"Teaming up with Heven means we can accelerate what we’ve always aimed to do: push drone technology to the edge of what’s possible."
The integration of Zepher's lightweight, quick-deployable drones with HevenDrones' hydrogen propulsion systems is anticipated to result in UAS with extended flight times and increased payload capacities. This development is particularly significant for military applications requiring persistent surveillance and logistics support in austere environments.
