US Army awards Heven AeroTech agreement for hydrogen-powered Z1 drone

The US Army has awarded Heven AeroTech a Basic Ordering Agreement covering its Z1 hydrogen-powered unmanned aerial system, marking a significant endorsement of hydrogen propulsion for military applications. The Z1 is a hydrogen fuel cell-powered UAS designed for long-endurance, low-acoustic-signature missions. The agreement allows the Army to place orders for the platform under a pre-negotiated framework, streamlining procurement for defence users. The award reflects growing defence interest in hydrogen VTOL and long-endurance unmanned platforms that can operate independently of traditional fuel logistics. Source: The Defense Post, March 2026.
