Tethered aerial operations provide continuous overwatch for hours or days without battery limitations.

Integrated EO/IR aerial sensing and surface-based sonar deliver situational awareness across domains.

Engineered for night operations, surf zones, flooding, and low-visibility conditions.

A mission-configurable payload design supports SAR-focused deployment with optional secondary applications.

Search and rescue operations often take place in environments where conventional tools struggle:
Autonomous surface mobility, long endurance, stable sensor base, communications hub.
Persistent EO/IR surveillance, spotlighting, communications relay.
Imaging and side-scan sonar for rapid localization.
Representative application areas include:
These areas reflect the broader operational relevance of the underlying technology and complement the company’s SAR-first focus.

deJongSmit is engaging with partners to translate the system concept into practical deployment pathways for SAR and maritime use cases.
