Abstract

An arrangement for cooling the gun barrel of a combat tank wherein the gun barrel is provided with helical cooling channels on its outer surface, and an insulation layer on at least the inner circumferential surfaces of the cooling channels. This reduces the IR signature of the gun barrel during combat and avoids deformation of the barrel under the influence of radiation from the sun.
