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 (15), the at least one ancillary device (15) is fixedly connected to a lifting body (16), 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 (16) are selected such that the lifting force acting in the water on the ancillary device (15) and the lifting body (16) compensates for the force of gravity acting on the ancillary device (15) and the lifting body (16).

The invention claimed is: 1. Underwater vessel having a pressure hull, a drive assembly, and at least one ancillary device arranged on the pressure hull; and wherein: the at least one ancillary device is fixedly connected to a lifting body, which has a lower density than the density of the water, with the density and volume of the lifting body being selected such that the lifting force acting in the water on the ancillary device with the lifting body compensates for the force of gravity acting on the ancillary device and the lifting body; the drive assembly has two or more propeller drives, which are accommodated in drive tubes, which are arranged distributed on the outside of the pressure hull and have a propeller protruding at one end of the tube; and each propeller drive has associated with it, as an ancillary device, a protection apparatus surrounding its propeller, and a lifting tube, which is fixedly connected to the protection apparatus and is pushed onto each drive tube as the lifting body. 2. Underwater vessel according to claim 1, wherein the lifting tube has an end section having a reduced outer diameter, and the protection apparatus has a fixing ring, which surrounds the end section and is fixed on the end section of the lifting tube. 3. Underwater vessel according to claim 2, wherein the outer diameter of the fixing ring is dimensioned to be equal to the outer diameter of the lifting tube such that the fixing ring and the lifting tube are flush with one another when the protection apparatus is pushed onto the lifting tube. 4. Underwater vessel according to claim 1, wherein the protection apparatus is made from metal or an impact-resistant plastic. 5. Underwater vessel according to claim 1, wherein the protection apparatus has a protective grating, which covers the propeller at one end, and a protective grating holder, which engages around the propeller and at whose one end the protective grating is fixed and at whose other end the fixing ring is arranged. 6. Underwater vessel according to claim 5, wherein the protective grating holder has axial webs, which are offset with respect to one another through circumferential angles, are bent back at an angle towards the fixing ring and are fixed to said fixing ring, and the protective grating is placed onto the free ends of the axial webs and fixed thereto. 7. Underwater vessel according to claim 5, wherein the protective grating has a ring and radial struts fixed to the ring, holes, which are offset through circumferential angles, are provided in the ring for the purpose of passing through the end sections of the axial webs, and the end sections of the axial webs are provided with a thread, with threaded nuts being screwed onto said end sections and fixedly clamping the protective grating on the protective grating holder. 8. Underwater vessel according to claim 7, wherein the holes provided in the ring are offset through the same circumferential angles. 9. Underwater vessel according to claim 1, wherein the drive assembly has four propeller drives. 10. Underwater vessel having a pressure hull, a drive assembly, and at least one ancillary device arranged on the pressure hull; and wherein; the at least one ancillary device is fixedly connected to a lifting body, which has a lower density than the density of the water, with the density and volume of the lifting body being selected such that the lifting force acting in the water on the ancillary device with the lifting body compensates for the force of gravity acting on the ancillary device and the lifting body; the ancillary device is an underwater antenna having an electroacoustic transducer arrangement; and the lifting body is arranged on that side of the underwater antenna which faces away from the direction in which sound is incident. 11. Underwater vessel according to claim 10, wherein the lifting body has a bearing surface for the purpose of bearing on the underwater antenna and a bearing surface for the purpose of bearing on the pressure hull or on a drive tube, said bearing surfaces in each case being matched to the contour of the underwater antenna or the pressure hull or the drive tube, and fixing means are provided which engage over the lifting body and can be fixed to the underwater antenna and to the pressure hull or to the drive tube. 12. Underwater vessel according to claim 6, wherein the protective grating holder axial webs are offset with respect to one another through the same circumferential angles.
