Fuzzy logic for depth control of Unmanned Undersea Vehicles
IEEE Journal of Oceanic Engineering, 1995Fuzzy logic is a viable control strategy for depth control of undersea vehicles. It has been applied to the low speed ballast control problem for ARPA's unmanned undersea vehicle (UUV), designed and built by Draper. A fuzzy logic controller has been designed and tested in simulation that issues pump commands to effect changes in the UUV depth, while ...

Hydrogen Fuel Cells for Unmanned Undersea Vehicle Propulsion
ECS Transactions, 2016The high efficiency of fuel cells combined with the high energy of hydrogen can be used to create energy systems for long endurance vehicles. As the automotive sector has developed fuel cells for this purpose, the same technology might enable long endurance unmanned undersea vehicles (UUVs).

Solid Oxide Fuel Cells in Unmanned Undersea Vehicle Applications
MRS Proceedings, 2006 ABSTRACTThe Navy is currently investigating solid oxide fuel cells (SOFCs) for the propulsion of unmanned undersea vehicles (UUVs). SOFCs are being targeted because of their potential to carry out extended missions, which are not possible using current battery technology.

Undersea communications between submarines and unmanned undersea vehicles in a command and control denied environment [PDF]
, 2015 Nuclear powered submarines are most vulnerable to detection and attack while at periscope depth. Submarines also have specific communication and time requirements they have to meet and the primary method of transmitting and receiving data is via satellite, which requires the submarine to be at periscope depth.

Recovering unmanned undersea vehicles with a homing and docking sonar
Proceedings of OCEANS 2005 MTS/IEEE, 2005There is a great deal of interest in deploying and recovering an unmanned undersea vehicle (UUV) with a submarine or a surface ship. This paper describes a homing and docking sonar (HDS) that was developed for a 21-inch diameter UUV and host platform.

Expanding Missions for Small Unmanned Undersea Vehicles (UUVs)
Volume 3: Materials Technology; Ocean Engineering; Polar and Arctic Sciences and Technology; Workshops, 2003Small unmanned undersea vehicles (UUVs), those less than 150 pounds, have many advantages for field operations over the larger models. The increase in number and capabilities of these vehicles is opening doors for an ever expanding number of applications.

US Navy unmanned undersea vehicle navigation
Proceedings of OCEANS'94, 2002The ability to guide and position an undersea vehicle with high precision lends itself to multiple missions, including mine warfare and undersea surveillance. In addition, precise navigation provides the capability to locate security threats and biological and oceanographic anomalies.
