Existing Operational Unmanned Systems as
Mobile Networked Nodes
An Undersea Distributed Network System (UDNS) is defined as a warfighting system consisting of sensors, unmanned vehicles, and platforms, all networked together to provide an accurate perception of the underwater battlespace. A key question is: How can the UDNS community leverage these components to experiment with innovative concepts, while minimizing investment in interim hardware? This paper focuses on existing Boeing unmanned vehicles that can support UDNS sensor and network experimentation. The underwater battlespace ranges from the sea floor to the sea surface, and from the deep ocean to the littorals. While manned platforms such as submarines are very capable over most of these regimes, unmanned vehicles operate capably over all these ranges and more. Unmanned vehicles offer additional benefits including force multiplication, covertness, and the ability to perform missions in areas denied to manned platforms. Key requirements for unmanned vehicles supporting UDNS include: · Fully autonomous behavior sufficient to perform

Existing mine detection/classification acoustic sensor suite (FLA, SLS). SAS and L-PUMA capable. Alternate payloads could replace existing comm and sensors. Vehicle drop weight could be replaced with additional payload. If vehicle is extended > 240", use an additional payload section.

planned missions and operate payload(s). Autonomy must handle both nominal and off-nominal conditions, without manned platform support. · Accurate internal navigation with minimal reliance on external navigation resets. · Communication and sensor payload support. Communication payloads include acoustic, laser, and/or RF communication link(s) to other unmanned vehicles or manned platforms. Sensor payloads include acoustic, ISR, and other sensors. Payload support includes volume and UUV operational considerations such as buoyancy/ballast/trim control, surfacing, and antenna extension/retraction. · Battery Endurance and Power sufficient for vehicle range/mobility, sensor payload(s) and communication payload(s) that meets mission needs. · Reliable launch, operation, and recovery from host platform (submarine or surface ship) that meets host compatibility (e.g. TEMPALT/SHIPALT) and supportability needs. Unmanned vehicles have been in development for
