Abstract

The installation space dimensions of a weapon system in the tower are complied with, and a loading space diameter of a caliber-larger weapon barrel is approximately maintained in relation to the smaller caliber. The required larger loading space volume for the caliber increase is predominantly achieved by an extension of the loading space of the caliber-larger weapon barrel relative to a loading space of the caliber-smaller weapon barrel itself. Since the loading space diameter of a larger caliber remains virtually unchanged, the outer dimensions of the caliber-larger weapon barrel also remain virtually unchanged compared to the outer dimensions of the caliber-smaller weapon barrel in the region of the loading part.

First claim

What is claimed is:

1. A weapon system comprising:
a blowback system, comprising a breech block; and
a replaceable barrel with a loading space,
wherein the replaceable barrel has a loading space lengthening compared with a loading space of a smaller-caliber barrel while maintaining a loading space diameter of the smaller-caliber barrel,
wherein the replaceable barrel has a caliber part with a larger caliber diameter than that of the smaller-caliber barrel, and
wherein the caliber part of the replaceable barrel is a 130 mm caliber part and the caliber part of the smaller-caliber barrel is a 120 mm caliber part.

2. A combat vehicle comprising a weapon system as claimed in claim 1 .

3. The combat vehicle as claimed in claim 2 , wherein the combat vehicle is a battle tank.

4. A weapon system, comprising:
a replaceable barrel configured to accommodate an ammunition cartridge, comprising:
a loading space; and
a caliber part,

wherein a length of the loading space is longer than a length of a loading space for a barrel accommodating an ammunition cartridge smaller than the ammunition cartridge of the replaceable barrel,
wherein a diameter of the caliber part is larger than a diameter of a caliber part for the barrel accommodating the ammunition cartridge smaller than the ammunition cartridge of the replaceable barrel,
wherein a diameter of the loading space is the same as a diameter of the loading space for the barrel accommodating the ammunition cartridge smaller than the ammunition cartridge of the replaceable barrel, and
wherein the ammunition cartridge of the replaceable barrel is a 130 mm ammunition cartridge and the ammunition cartridge of the barrel accommodating the ammunition cartridge smaller than the ammunition cartridge of the replaceable barrel is a 120 mm ammunition cartridge.
