Various techniques are disclosed for the detection of discrepancies between imaged maritime vessels and received identification information. In one example, a method includes capturing an image of a maritime vessel and processing the image to extract information associated with the vessel. The method also includes receiving automatic identification system (AIS) data, comparing the extracted information to the AIS data, and generating an alarm in response to a discrepancy detected by the comparing. Additional methods, systems, and devices are also provided.

An apparatus and method transports, launches, and recovers an unmanned undersea vehicle (UUV) on a boat. A pair of support rails secures the UUV to the boat during the transport across a body of water on the boat. The support rails support the UUV in sliding movement along the support rails during the launch from the boat into the body of water and during the recovery from the body of water onto the boat. A ramp is deployed that extends the support rails into the body of water through a stern of the boat. The ramp includes a pair of alignment rails for aligning the UUV with the support rails during the recovery. A winch pulls the UUV out of the body of water during the recovery, with the winch pulling the UUV into the alignment rails and then onto the support rails in the boat.

Methods and apparatus for deploying an unmanned marine vehicle into water are disclosed. The unmanned marine vehicle includes a float and a glider connected by a tether. The float is selectively retained in a buoyant frame by a float clamp assembly. A glider retainer assembly is coupled to the buoyant frame and selectively retains the glider. The glider retainer assembly and the float clamp assembly execute a deployment sequence for deploying the unmanned marine vehicle from the apparatus. In some embodiments, the apparatus is self-propelled to permit remote operation and deployment of the unmanned marine vehicle.

Methods and apparatus for retrieving an unmanned marine vehicle from water are disclosed. The unmanned marine vehicle includes a float and a glider connected by a tether. The apparatus includes a buoyant frame having spaced frame arms defining a receiving bay sized to receive the float, and the buoyant frame includes a front end defining an opening of the receiving bay. A glider recovery assembly is coupled to the buoyant frame and includes a first tether guide coupled to the buoyant frame, and a second tether guide coupled to the buoyant frame, wherein the first tether guide and the second tether guide are cooperatively shaped to define a tether capture gap having a tether inlet adjacent the front end of the buoyant frame and a tether stop positioned rearward of the tether inlet.

A pressure tolerant energy system may comprise a pressure tolerant cavity and an energy system enclosed in the pressure tolerant cavity configured to provide electrical power to the vehicle. The energy system may include one or more battery cells and a pressure tolerant, programmable management circuit. The pressure tolerant cavity may be filled with an electrically-inert liquid, such as mineral oil. In some embodiments, the electrically-inert liquid may be kept at a positive pressure relative to a pressure external to the pressure tolerant cavity. The energy system may further comprise a pressure venting system configured to maintain the pressure inside the pressure tolerant cavity within a range of pressures. The pressure tolerant cavity may be sealed to prevent water ingress.
