Abstract
A rigid thermal sleeve 5 mountable over at least part of a gun barrel 3 in such a way that it is symmetrical about a longitudinal plane A--A to provide a reduced thermal image and radar cross section. The sleeve 5 comprises thermally insulating material 13 between an inner skin 15 and an outer skin 17. The outer skin 17 is arranged to have two mutually convergent planar faces 7,9, each one of which makes up at least 15% of the outer surface of the sleeve 5 and which have a mutual line of convergence extending externally and longitudinally of the sleeve 5.
