An underwater body having a movable component which can be moved into a retracted position and, as a result, increases the volume of the underwater body. In addition, a method is disclosed for operating such an underwater body. An expansion means conducts a fluid into a hollow space. The hollow space is operatively connected to the movable component. When the fluid is conducted into the hollow space, the movable component is moved into the extended position relative to the shell of the underwater body. The fluid in the hollow space hardens. The hardened fluid in the hollow space holds the movable component in the extended position.

An underwater vehicle may include a first propulsion element disposed on a first swivel holder, a first drive motor that is able to drive the first propulsion element, and a swivel mechanism that is able to move the first swivel holder relative to an outer hull of the underwater vehicle from a swiveled-in position into a swiveled-out position. The underwater vehicle can detect a given event automatically under water. In response to the detection of the event, the underwater vehicle may activate the swivel mechanism. The activated swivel mechanism may then move the first swivel holder into the swiveled-out position.

The invention relates to a launch apparatus for an Unmanned Underwater Vehicle&#x2014;in particular, for an Autonomous Underwater Vehicle or for a Remotely Operated Vehicle&#x2014;with a launching tube having an inner wall and an outlet, and the Unmanned Underwater Vehicle contained within the launching tube, whereby the Unmanned Underwater Vehicle has a vehicle casing with a vehicle casing inhomogeneity, such that an ejection of the Unmanned Underwater Vehicle causes different contact loads between the vehicle casing and the inner wall, whereby the Unmanned Underwater Vehicle has a detachable compensating form, which is designed in such a way that the vehicle inhomogeneity is compensated, such that the result is a combination of the Unmanned Underwater Vehicle and the detachable compensating form, the combination whereof, when ejected, causes a substantially more uniform contact load to occur between the combination and the inner wall.

The invention relates to a mockup with an optical transmission path, which optically connects the optical entrance to the optical exit, wherein an optical attenuator is arranged in the optical transmission path, wherein an optical condition of the transmission path is adjusted by means of the optical attenuator so that an optical transmission behavior of a wound optical fiber is simulated. The invention also relates to a mockup system, underwater vessel and/or sinker, a transfer mechanism, and a vessel, together with a training method with a mockup, which is deployed in an underwater vessel and/or in a sinker.

The invention concerns a group of vessels (), having an unmanned surface vessel () and an unmanned underwater vessel (), wherein the underwater vessel comprises a location device, in particular a sonar device, for sensing location data () in the underwater area and one evaluation unit or more evaluation units, and the evaluation unit or the evaluation units are arranged in such a manner that these comprise detection means () for detecting () a contact (MILEC) with the aid of the sensed location data () and with classification means () for classifying () the detected contact (MILEC) as a mine-like contact (MILCO) or non mine-like contact (NONMILCO), whereby classification is accomplished by comparing the contact (MILEC) with known mine information so that a mine-like contact (MILCO) can be identified as a mine contact (MINE) or as another object (NOMBO).

The present disclosure provides a method for clearing weapons that have been sunk in waterways using a weapon clearance appliance. The weapon clearance appliance comprises means for detachable connection to an unmanned underwater vehicle, so that the underwater vehicle is a safe distance away when the weapon is detonated. The volume of the weapon clearance appliance is chosen such that the buoyancy force which acts on the weapon clearance appliance under water compensates for the force of gravity acting on the weapon clearance appliance. Therefore, the weapon clearance appliance has neutral buoyancy, as a result of which, after the weapon clearance appliance has been released from the underwater vehicle, there is no need to retrim the underwater vehicle. Therefore, there is no need for trimming devices on the underwater vehicle.

A method for detecting anomalies on a submarine object, in particular in the submarine region on a hull of a moored warcraft, which method carries out very reliable sensing of the submarine object by way of an unmanned small submarine vehicle that is equipped with simple sensor equipment, such as an acoustic sensor for measuring distances and a barometric cell for determining depth, and which method obtains a profile of the submarine object by navigating the small submarine vehicle with a constant transversal distance to the submarine object, in which profile an anomaly present on the submarine object becomes is apparent from the profile line.

The invention relates to a weapon clearance appliance for clearing weapons, such as underwater mines or munitions which have been sunk in waterways, under water by detonation of the weapon. In this case, the weapon clearance appliance is provided with means for detachable connection to an unmanned underwater vehicle, so that the underwater vehicle is a safe distance away when the weapon is detonated. In order to allow the use of conventional small underwater vehicles, the volume of the weapon clearance appliance is chosen such that the buoyancy force which acts on the weapon clearance appliance under water compensates for the force of gravity acting on the weapon clearance appliance. Therefore, the weapon clearance appliance has neutral buoyancy, as a result of which, after the weapon clearance appliance has been released from the underwater vehicle, there is no need to retrim the underwater vehicle. There is therefore no need for trimming devices on the underwater vehicle. The invention also relates to an underwater vehicle having a weapon clearance appliance of this kind, and to a method for clearing weapons using a weapon clearance appliance of this kind.

An appliance for lowering and tracking an underwater vessel includes a carrier arranged on an end of a holding cable; a holding device on the carrier used to receive/release the underwater vessel with a controllable holding element; and a tracking device arranged on the carrier and used for acoustically determining the position of the underwater vessel lowered into the water. As a result, a light, compact lowering appliance is provided that is suitable for handling vessels on small platforms and ensures acoustically undisturbed operation of the tracking device, which is arranged on one end of the carrier, the carrier being mounted such that it can be pivoted on the holding cable in an articulated manner in a central longitudinal region thereof. Following release of the underwater vessel from the holding element, a pivoting device pivots the carrier including the tracking device out of a lowering position, into a tracking position.

Appliance for deployment and tracking of an unmanned underwater vehicle

With an unmanned underwater vessel having a pressure hull, drive assembly and at least one ancillary device arranged on the pressure hull, for example a propeller protection apparatus (), the at least one ancillary device () is fixedly connected to a lifting body (), which has a lower density than the density of the water, in order to make it possible to replace the ancillary devices or to arrange additional ancillary devices on the pressure hull without changing the trim of the underwater vessel as a result. The density and volume of the lifting body () are selected such that the lifting force acting in the water on the ancillary device () and the lifting body () compensates for the force of gravity acting on the ancillary device () and the lifting body ().
