Theseus (AUV)
Theseus is a large autonomous underwater vehicle (AUV) designed for laying fibre-optic cable on the seafloor. History In 1987, the Canadian government released a long-awaited white paper on defence; one of the key points in this paper was Canada's commitment to maintaining sovereignty over its Arctic waters, through both the acquisition of nuclear submarines and advances in passive subsea surveillance techniques. Project Spinnaker was a defence research project initiated to develop the technologies needed to deploy acoustic listening posts on the seafloor in Canada's Arctic Archipelago. These arrays needed to be deployed in deep waters on the edge of the Continental Shelf; since these waters were ice-covered year round, a novel solution was needed to lay trunk cables from on-shore data processing centres out to the arrays. Project Spinnaker was the brainchild of the Defense Research Establishment Pacific (DREP), a defence research laboratory specializing in Arctic acoustics. T ...

Autonomous Underwater Vehicle
An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring continuous input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV). Underwater gliders are a subclass of AUVs. Homing torpedoes can also be considered as a subclass of AUVs. History The first AUV was developed at the Applied Physics Laboratory at the University of Washington as early as 1957 by Stan Murphy, Bob Francois and later on, Terry Ewart. The "Self-Propelled Underwater Research Vehicle", or SPURV, was used to study diffusion, acoustic transmission, and submarine wakes. Other early AUVs were developed at the Massachus ...
