A mortar includes at least one barrel mounted movably over a ball journal in a bottom supporting device, and an aiming device serving to aim the barrel vertically and horizontally. In order to be able to aim the barrel of the mortar automatically in a simple and cost advantageous manner, the aiming device preferably comprises a carriage that can be moved along guideways essentially horizontally towards or away from the barrel. At the carriage, the first end region of a pivoted arm is mounted so that it can be rotated about a pivot axis, and the second end region of the pivoted arm is connected with a spherical plain bearing, guiding the barrel. The spherical plain bearing embraces a housing part, which is open at its end faces and in which an inner part is mounted spherically (rotatably), which contains a cylindrical barrel guide, for movably accommodating the barrel.

1. A mortar comprising: (a) a bottom supporting device;(b) at least one weapon barrel mounted to move via a ball-ended rod on the bottom supporting device; and(c) an aiming system operable to aim elevation and azimuth of the at least one weapon barrel, wherein the aiming system comprises: i. a hinge
1. A mortar comprising: (a) a bottom supporting device;(b) at least one weapon barrel mounted to move via a ball-ended rod on the bottom supporting device; and(c) an aiming system operable to aim elevation and azimuth of the at least one weapon barrel, wherein the aiming system comprises: i. a hinged bearing having a housing part, wherein the housing part has two open end faces and on an outside of the housing part a pivoting arm is mounted so that the pivoting arm is rotatable about a horizontal axis, and a rotatably mounted inner part is located in the pivoting arm, wherein the rotatably mounted inner part is connected to a cylindrical barrel guide for movable accommodation of the at least one weapon barrel, and the rotatably mounted inner part facilitates a de-coupled, axis-parallel installation of a system for determining geographical location to an interior component, wherein the system for determining geographical location comprises a gyroscope system, andii. a carriage that moves along at least one guide path substantially horizontally toward the at least one weapon barrel or away from the at least one weapon barrel, wherein an end area of the pivoting arm is operably mounted on the carriage. 2. The mortar as claimed in claim 1, wherein a first end area of the pivoting arm is mounted on the carriage so that the pivoting arm is rotatable about a pivoting axis arranged at right angles to a plane of the carriage, and a second end area of the pivoting arm is connected to the hinged bearing, wherein the hinged bearing is disposed at a distance from the bottom supporting device and the hinged bearing guides movement of the at least one weapon barrel. 3. The mortar as claimed in claim 2, wherein, in order to move the carriage along the at least one guide path, the carriage is connected to a first drive unit that comprises a first actuating motor. 4. The mortar as claimed in claim 3, wherein, in order to rotate the pivoting arm, the pivoting arm is connected to a second drive unit that comprises a second actuating motor. 5. The mortar as claimed in claim 4, wherein a first device for determining a three-dimensional barrel orientation is attached to the cylindrical barrel guide of the hinged bearing, and the first device acts on the first drive unit and the second drive unit via an electronic control device. 6. The mortar as claimed in claim 5, wherein a manual control device is provided on the housing part for manual adjustment of the hinged bearing in azimuth. 7. The mortar as claimed in claim 1, wherein the at least one guide path is a guide strip in the form of a rail and is arranged on or adjacent to a base frame. 8. The mortar as claimed in claim 1, wherein, in order to rotate the pivoting arm, the pivoting arm is connected to a drive unit that comprises an actuating motor. 9. The mortar as claimed in claim 1, wherein the pivoting arm includes two parts in the form of rods or tubes, wherein the two parts are arranged parallel to one another and surround the housing part of the hinged bearing at sides of the housing part, and the two parts are connected to the housing part via bearing journals so that the two parts pivot. 10. The mortar as claimed in claim 2, wherein the pivoting arm includes two parts in the form of rods or tubes, wherein the two parts are arranged parallel to one another and surround the housing part of the hinged bearing at sides of the housing part, and the two parts are connected to the housing part via bearing journals so that the two parts pivot. 11. The mortar as claimed in claim 1, wherein the interior component comprises an electronic control unit.
