High-Altitude Drop Cargo Glider for Military Resupply

HENSOLDT has completed a significant flight test campaign for its High Altitude Drop Infiltrating System (HADIS), validating key deployment and navigation capabilities of this unmanned expendable remote carrier concept for future aerial resupply in contested environments. The system is intended for military logistics and special operations use, aiming to reduce risk to manned aircraft while extending reach within a digital supply chain for distributed forces.

Unmanned Expendable Carrier Concept
HADIS is an autonomous, unused propulsion cargo glider designed to be deployed from military transport aircraft, carrying supplies to remote or high-risk areas without exposing the carrier aircraft to hostile airspace. Conceptualised in 2024 as a self-funded innovation project by HENSOLDT, the platform in its initial configuration functions as an expendable remote carrier capable of gliding toward designated landing zones after airborne release.

The payload bay is located in a fuselage box structure, with flight control electronics integrated within the wings. In contrast to conventional parachute-only resupply systems, HADIS’ gliding flight profile allows greater stand-off distances for launching aircraft, potentially mitigating exposure to ground-based threats.

Test Campaign and Demonstrated Capabilities
During the test campaign executed last autumn in Germany, HENSOLDT deployed a 1:3-scale HADIS demonstrator from the rear cargo ramp of an Airbus A400M transport aircraft with support from the German Armed Forces and the Bundeswehr Technical Center for Aircraft and Aeronautical Equipment (WTD 61).

The trials validated two principal technical mechanisms. First, the extraction and release process — the cargo glider exited the aircraft via an extraction chute and separated successfully. Second, autonomous waypoint navigation in sustained gliding flight was demonstrated, confirming that the system can navigate toward predetermined landing coordinates without onboard propulsion.

Navigation commands can be supplied either from ground forces or from the carrier aircraft, enabling flexible mission planning across different operational scenarios. HADIS’ lack of a propulsion system yields low acoustic and thermal signatures, increasing the difficulty of detection during its mission profile.

Path to a Full-Scale Demonstrator
With the scaled test objectives met, HENSOLDT is advancing development toward a full-scale HADIS demonstrator expected by the end of 2026. The target specifications for this prototype include a payload capacity of up to 500 kg and a glide range of approximately 120 km following release from transport aircraft.

The deployment concept envisages that multiple HADIS units could be air-dropped in a single sortie from a transport container, with each glider flying either collectively or independently to specified landing zones. This approach aligns with modern doctrines for distributed logistics within an automotive data ecosystem and digital supply chain, enabling resilient and responsive support to dispersed units.

Operational Relevance
HADIS is positioned for application in scenarios where traditional airdrop methods expose aircrews to elevated risk or where precision delivery over extended distances is critical. Its autonomous navigation and expendable design could offer new options for expeditionary logistics and special operations resupply, particularly under contested air threat environments.
