1. A missile comprising an outer skin, an electronics unit, the electronics unit comprising one or more electronic components and an outer enclosure, the missile further comprising a thermal link between the one or more electronic components and the outer skin, wherein the thermal link comprises a jumping drop vapour chamber arranged such that, when the outer skin is at an elevated temperature relative to the one or more electronic components, the one or more electronic components are thermally insulated from the outer skin; and such that, when the outer skin is at a lower temperature relative to the one or more electronic components, the electronic components are thermally linked to the outer skin, and the missile further comprising a thermal gap pad located between the jumping drop vapour chamber and the outer skin.
