Abstract: A system for monitoring a remote underwater location using an unmanned underwater vessel (5). The system includes an unmanned surface vessel (8), a communication unit (7) for submerged location and connected to the unmanned surface vessel (8) and in which the unmanned surface vessel has a position tracking control system for controlling the position of that vessel on a body of water and relative to the unmanned underwater vehicle (5). The communication unit (7) has a first wireless communication arrangement for communication with the unmanned underwater vehicle, a second wired communication arrangement (10) for communication with the unmanned surface vessel and the unmanned surface vessel has a third communication arrangement for communication with an operator or observer (1) remote from the unmanned surface vessel and the unmanned underwater vehicle.

Abstract: A charge deployment system for ordnance neutralization. The system is suited to deploying multiple disposal charges to neutralize multiple items of ordnance, in particular mines, in a single sortie. The system includes at least one deployment unit, each unit including a housing for stowing a charge in a stowed position; means for mounting a charge within the deployment unit; means for controllably moving a charge and mounting means from the stowed position to a deployment position; means for controllably releasing a charge from the mounting means; and a controller for controlling each moving means. It further relates to an unmanned vehicle, such as an unmanned underwater vehicle, including such a charge deployment system for ordnance neutralization.
