The invention relates to a remote-controllable underwater vehicle (1) with a device for uncovering submerged objects, and to an underwater system with an underwater vehicle (1) of this type. In order to permit cost-effective and safe removal of objects, to which access is difficult, from the bottom of a body of water, in particular weapons to which access is difficult, according to the invention the device for uncovering submerged objects comprises a working nozzle (8) which guides a stream of water, and a counterpressure nozzle (17) acting counter to the working nozzle (8).

The invention relates to an apparatus for transferring data and to a method for transferring data from or to an underwater pressure body 30 having a bulk storage apparatus 10. The bulk storage apparatus 10 is normally located within the underwater pressure body 30, such that only by means of a time-consuming disassembly of the underwater pressure body 30 can the bulk storage apparatus 10 be disconnected from a computation unit 32 of the underwater pressure body 30, and the data of the separate bulk storage apparatus 10 can be transferred by passing on to the bulk storage apparatus 10. The problem of time-consuming transfer of data is solved by means of an apparatus according to the invention which comprises the bulk storage apparatus 10, which has a pressure-resistant insulation body 24 through which water cannot pass and which has no air in it, and which can be detachably connected to a connecting apparatus 36 which is arranged on the outside of the underwater pressure body 30. There is therefore no need to disassemble the underwater pressure body 30 in order to remove the bulk storage apparatus 10, and the time for transferring the data is substantially shortened.

The invention relates to a method for identifying changes of course and/or speed for a destination using a multiplicity of measured bearing angles (22) which are ascertained by virtue of the directionally selective reception of sound waves emitted from the destination using an arrangement of water borne sound pickups (86) in a sonar receiving installation. To this end, a first bearing profile (40) is calculated from a predetermined number k of most recently ascertained bearing angles, and a second bearing profile (42) is calculated from a predetermined number i of earlier bearing angles ascertained before the k bearing angles. An expected bearing angle (56, 58) for each of the two bearing profiles (40, 42) is calculated at a current time (54) and is used to form a bearing angle difference | d |. This bearing angle difference | d | can be compared with a plurality of threshold values C1, C2, wherein an intersection point (72) for the bearing profiles (40, 42) and an associated target manoeuvre time (74) are ascertained when one of the threshold values C1, C2 is reached and are output together with an information signal (75) relating to the identification of the target manoeuvre. The invention also relates to an apparatus for carrying out such a method.
