A method for surveying a body of water includes providing a plurality of vehicles to a body of water. Each the plurality of vehicles includes a vehicle body, an electric-propulsion motor system mounted on the vehicle body, a rechargeable battery, at least one sonar device attached to the vehicle body, and a first communication device. The method also includes submerging each of the plurality of vehicles in the body of water, surveying an area, using the at least one sonar device, to map the body of water and to determine a location of each of the plurality of vehicles, and determining, based on the surveying, that a target object is detected within the area. The method also includes resurfacing each of the plurality of vehicles and transferring data, using the first communication device, between at least two of the plurality of vehicles at the surface of the body of water.

The present disclosure relates to methods, apparatuses, and systems for unmanned underwater vehicles capable of operation in the Arctic region. An example unmanned underwater vehicle includes: a hull; one or more guide rails extending from the hull and attached to the hull by one or more legs; a vertically-deployed mast, wherein the vertically-deployed mast is configured to penetrate through an ice sheet; and a communications antenna, wherein the communications antenna is deployed with the vertically-deployed mast and enables communication above the ice sheet. The dorsally-located guide rails of an example define an extended position and a retracted position, wherein the guide rails disposed in the extended position are disposed further from the hull than the guide rails disposed in the retracted position. Embodiments described herein include systems employing air-deployable buoys, water-deployed buoys and small UUVs, and ice-penetrating buoys to support communications in the Arctic region.

A device for containing and releasing sonobuoys, comprising a carousel rotatable about a respective axis X of longitudinal extension and having a lower portion and an upper portion, each of which endowed with a plurality of seats for housing respective sonobuoys; each seat comprising a support system for supporting the sonobuoy from below; characterised in that each seat further comprises a plurality of retaining elements, each of which switchable between a configuration of laterally retaining a respective sonobuoy, wherein it defines in the seat a housing volume for the sonobuoy, and a configuration of access to the seat in order to house the sonobuoy in the seat.

A remote launcher includes a base frame, a cradle, a cradle actuator, and a launch control system. The cradle is pivotably coupled to the base frame and includes one or more skids that are configured to receive and support an unmanned water-based deployable. The cradle actuator is coupled to the base frame and to the cradle. The launch control system includes a communication interface, a processor, and memory having instructions. The instructions direct the launch control system to receive, via the communication interface, one or more wireless launch signals and then, in response thereto, generate at least one cradle control signal to enable the cradle actuator to incline the cradle to a launch angle.
