H2D55

H2D55 is Heven AeroTech’s hydrogen-powered multirotor aircraft for intelligence, surveillance, overwatch and tactical missions. It carries up to 4.5 kilograms of payload at a maximum takeoff mass of 29 kilograms and can remain airborne for as long as three hours with a payload installed. The aircraft cruises at up to about 35 kilometres per hour and uses vertical takeoff and landing for confined operating sites.

The platform is designed around replaceable hydrogen tanks that can be exchanged in under five minutes, matching its sub-five-minute field assembly time. Low acoustic and thermal signatures support observation work where detectability matters, while the multirotor layout allows stationary overwatch and precise landing. H2D55 is a complete aircraft system, distinct from Heven’s larger Z1/H2D250 and other hydrogen platforms.
