Abstract: A remote-operable firing pin safety catch is provided. A mechanical firing pin safety catch is supplemented by a further electrically remote-operable safety catch device, wherein it is basically the case that firing is possible only when the safety catch of a firing pin has been both locally mechanically released and also electrically released by means of a remote controller. As an electrical firing pin safety catch, an electric actuator is incorporated into the mechanical firing pin safety catch.

Abstract: A device and a method for performing thermal compensation of a weapon barrel of a gun having at least one weapon barrel which is mounted in a barrel cradle and in a barrel support as a prolongation of the barrel cradle. A plurality of temperature sensors are integrated into the barrel cradle and the barrel support and are connected via data lines to a data box. The data box is connected to a data processing device, which acts on actuators of the gun. The temperature at the barrel cradle and the barrel support is measured by temperature sensors. The temperature difference between upper and lower sides and right-hand and left-hand sides of the barrel cradle and the barrel support are determined. The barrel inclination is then calculated from these values, and the barrel inclination is then compensated by adjusting the orientation of the weapon barrel in its azimuth and/or elevation.
