An AUV support system includes: a surface ship; an underwater station configured to support an AUV which autonomously sails in water; and a cable connecting the surface ship and the underwater station. The cable includes: a first cable portion extending downward from the surface ship through a water surface when the underwater station is suspended in the water by the cable from the surface ship that is in a stop state on the water; a second cable portion extending upward from a lower end portion of the first cable portion when the underwater station is suspended as above; and a third cable portion extending downward from an upper end portion of the second cable portion and connected to the underwater station when the underwater station is suspended as above.

A field configurable autonomous vehicle includes modular elements and attachable components. The vehicle can be assembled from these modular elements and components to meet desired mission and performance characteristics without the need to purchase specially designed vehicles for each mission. The vehicle and other autonomous vehicles can be transported to the location of use by a ferry vehicle thereby conserving vehicle systems and resources and expanding the vehicle utility.

The present disclosure is directed to delivering nodes to an ocean bottom. A system can include a tether management system (TMS) towed by a vessel that moves on the surface of the ocean in a first direction. An underwater vehicle (UV) can be connected to the TMS and can move in a second direction that is different from the first direction. A thruster can be coupled to the TMS can cause the TMS to move in a third direction that is different from the first direction. A control unit can control the thruster to move the TMS in the third direction based on a cross-line location policy, and cause the UV to deploy nodes to target locations on the ocean bottom.
