Abstract

A military vessel may include a directable weapon and an antenna. The antenna can be swiveled from a first position, in which the antenna is disposed essentially vertically, into a second position, in which a height of the antenna above the military vessel is reduced to increase a directing range of the directable weapon compared to the first position. A method for operating a military vessel with a directable weapon and an antenna may involve swiveling the antenna from a first position, in which the antenna is disposed essentially vertically, into a second position, in which the height of the antenna above the vessel is reduced to increase the directing range of the weapon compared to the first position.

First claim

What is claimed is:

1. A military vessel comprising:
a directable weapon; and
an antenna configured to be swiveled from a first position in which the antenna is disposed substantially vertically to a second position in which a height of the antenna above the vessel is reduced to increase a directing range of the directable weapon relative to the first position,
wherein the antenna is configured as a linear antenna.

2. The military vessel of claim 1 wherein the antenna is disposed substantially horizontally in the second position.

3. The military vessel of claim 1 wherein a free end of the antenna is disposed in a region of a side of a hull of the military vessel in the second position.

4. The military vessel of claim 1 wherein the antenna swivels in a swivel plane that encloses an angle with a longitudinal axis of a hull of the military vessel.

5. The military vessel of claim 4 wherein the swivel plane is disposed perpendicularly to the longitudinal axis of the hull.

6. The military vessel of claim 4 wherein the swivel plane is parallel to an imaginary connecting line extending between the antenna and the directable weapon.

7. The military vessel of claim 1 wherein the antenna swivels about a swivel axis that is disposed in an edge region of a deck of the military vessel.

8. The military vessel of claim 1 further comprising a locking bolt for locking the antenna in at least one of the first position or the second position.

9. The military vessel of claim 1 further comprising a motorized swiveling device for swiveling the antenna.

10. The military vessel of claim 9 wherein the motorized swiveling device is rigidly or elastically connected to a deck of the vessel.

11. The military vessel of claim 9 wherein the motorized swiveling device comprises a rotatably supported shaft on which the antenna is disposed.

12. The military vessel of claim 11 wherein the motorized swiveling device comprises a housing and a sealing device for sealing against water that is disposed between the housing and the shaft.

13. The military vessel of claim 1 wherein the antenna is configured as a rod-shaped antenna.

14. The military vessel of claim 1 further comprising:
at least one of a transmitter or a receiver; and
an adjustment device for adapting antenna impedance to the at least one of the transmitter or the receiver, wherein the adjustment device is adjustable such that the antenna impedance is adjustable when the antenna is in the first and second positions.

15. A method for operating a military vessel that includes a directable weapon and a linear antenna, the method comprising swiveling the linear antenna from a first position in which the linear antenna is substantially vertically disposed to a second position in which a height of the linear antenna above the military vessel is reduced to increase a directing range of the directable weapon relative to the first position.

16. The method of claim 15 comprising swiveling the linear antenna to the second position if the directable weapon adopts at least one of a predetermined elevation directing position or a predetermined azimuth directing position.

17. A method for operating a military vessel that includes a directable weapon and an antenna, the method comprising swiveling the antenna from a first position in which the antenna is substantially vertically disposed to a second position in which a height of the antenna above the military vessel is reduced to increase a directing range of the directable weapon relative to the first position, and swiveling the antenna to the second position if the directable weapon adopts at least one of a predetermined elevation directing position or a predetermined azimuth directing position.
