Unique Unmanned System- C-Enduro

Unmanned systems are available in many different designs. They have the option to be equipped with numerous and varying sensors, types of propulsion and control systems.

The C-Enduro by ASV Unmanned Marine Systems is a long endurance maritime unmanned surface vehicle. When long term data acquisition is a necessary function the C-Enduro is a practical platform as it can be deployed for 30-90 days at sea, depending on its configuration. A platform that can operate for up to 3 months at a time is not entirely unique, however it is a strong asset. This combined with its mobility, ruggedness, and ability to tailor its power system to climatic conditions creates a very capable platform. The C-Enduro can use diesel or methanol, but also has energy harvesting technology utilizing wind turbines and solar panels, which aids in its deployability. With two brushless DC motors the unmanned vessel can travel at 6.5 knots.  The carbon fiber hull provides a strong and efficient design that is also self-righting, ideal for an ocean-going vessel.  At approximately 14 feet in length, 8 feet wide, 9 feet tall (including antennae), a draft of less the 1 and a half feet and a weight of 771lbs the platform classifies as a lightship. The size and weight allow a single person the capability of launching from a pier or boat launch via truck and trailer. By radio/satellite the operator can control the vessel semi-autonomously or configure for full autonomy. A wide range of sensors can be fitted to the unmanned vehicle including cameras, wave measurement, sonar, and even electronic warfare. A winch gives the ability to lower sensors or devices to greater depths for a broader range of capabilities. This allows the C-Enduro to fulfill multiple roles from environmental monitoring and oceanographic data collecting to security. Overall, I would rate the design and effectiveness of the C-Enduro highly. It fits the roles and capabilities for an unmanned vehicle concept I had previously thought should be employed. I think a small variation that could be implemented to increase the spectrum and range of capability is to incorporate search and rescue functions. This might not mean that any further sensors are required, perhaps thermal imaging could be useful, but lifesaving equipment such as flotation devices, a small inflatable raft, and possibly neoprene items.
