Coastal search and rescue missions often involve rough seas, darkness, drift, and rapidly changing conditions. Conventional drones have limited endurance, while crewed assets can expose responders to unnecessary risk.
deJongSmit’s integrated system combines persistent aerial awareness, stable surface operations, and optional subsurface sensing to support safer and faster decision-making.
The tethered UAV maintains continuous overwatch above the search area, while the USV remains on station as a mobile operational platform.
A more persistent SAR capability when time, weather, and visibility matter most.
Flood incidents create chaotic environments where access is restricted, visibility is poor, and communications may be disrupted. Response teams need rapid understanding of where people are stranded, which routes remain open, and how conditions are evolving.
deJongSmit’s integrated system combines mobile surface operations with persistent aerial awareness to support safer and faster response.
The USV can navigate flooded streets, waterways, and urban edges while the tethered UAV provides elevated EO/IR visibility and temporary communications relay capability.
Persistent awareness when conventional access is no longer possible.


Ports, terminals, offshore assets, and coastal infrastructure require continuous monitoring across wide areas, often in low light or poor weather conditions.
deJongSmit’s platform provides persistent surface presence with elevated aerial awareness to support inspection, perimeter monitoring, and rapid incident assessment.
The USV can patrol designated zones while the tethered UAV delivers EO/IR visibility and enhanced situational awareness without requiring constant crewed deployment.
A flexible monitoring capability built on the same safety-first architecture.
Coastal zones, ports, rivers, and shallow waters often require regular data collection where access is difficult, conditions change quickly, or crewed operations are costly.
deJongSmit’s platform combines persistent surface presence with modular payload options to support hydrographic, environmental, and inspection missions.
The USV can carry sonar, cameras, or water-quality sensors while the tethered UAV provides overhead awareness, positioning support, and rapid visual assessment.
A safer and more efficient way to collect data in complex environments.


Offshore wind farms and marine energy assets operate in demanding environments where weather, distance, and safety constraints increase operational cost and complexity.
deJongSmit’s platform can provide persistent surface presence with elevated aerial awareness to support inspection, monitoring, and operational readiness around offshore assets.
The USV can operate near turbines or offshore structures while the tethered UAV provides EO/IR visibility, close-range inspection views, and rapid situational awareness without exposing personnel unnecessarily.
A safer and more efficient support layer for offshore operations.
