A vacuum insulation layer is wrapped around the length of a warhead to thermally insulate the warhead from fire or aerodynamic heating. The vacuum insulation layer may be integrally formed into the warhead casing or provided as a sleeve that may be permanently or removably positioned about the warhead casing. The vacuum insulation layer is held under vacuum with a pressure of less than 25 Torr and a thermal conductivity Tcond_vac of less than one-third of the thermal conductivity of air Tcond_air.

Vacuum insulated warhead

A heavy inert gas insulation layer is wrapped around the length of a warhead to thermally insulate the warhead from fire or aerodynamic heating. The insulation layer may be integrally formed into the warhead casing or provided as a sleeve that may be permanently or removably positioned about the warhead casing. The insulation layer contains an inert gas such as Argon, Krypton, Xenon or a synthetic gas having a density of at least 1.5 kg/mand a thermal conductivity Tcond_gas no greater than two-thirds of the thermal conductivity of air Tcond_air.
