The present invention relates to a system for attaching a device to an object, comprising: an attachment device for attaching the device to an object, the attachment device having a trigger for triggering activation of the attachment device; a releasable coupling device for releasably coupling the attachment device to a deployment system. The releasable coupling device comprising: a housing; a trigger system, configured to trigger the attachment device trigger; and a retaining system, configured to releasably retain the attachment device. The releasable coupling device is configured such that: in a first configuration, the trigger system is in a disarmed state; in a second configuration, the trigger system is in an armed state, such that movement of the attachment device relative to the housing of the releasable coupling device activates the trigger of the attachment device; and in a third configuration, the retaining system releases the attachment device. The invention is particular of use in attaching an ordnance clearance charge to underwater ordnance. The invention further relates to an unmanned underwater vehicle comprising such an attaching system.

Systems and methods are provided for underwater use. In one example the system includes an autonomous mother unmanned underwater vehicle (AMUV) and one or more auxiliary unmanned underwater vehicles (UUV). The AMUV is configured for autonomously searching for and detecting undersea objects potentially present in an undersea region of interest (ROI), for generating object information relating to the objects detected thereby to enable identification of at least one object of interest (OOI) among the detected objects, and for selectively transporting the UUV to at least within a predetermined distance from a location of the OOI. The UUV is configured for interacting with the OOI at least within the predetermined distance. Such a system is further configured for providing verification information indicative of the interaction between the UUV and the OOI. The AMUV includes a communications system at least configured for transmitting at one or both of the verification information and the object information.
