An unmanned aerial launch vehicle (UAV) launch apparatus is disclosed that includes a UAV (400) having an exterior surface, an aerial vehicle (AV) tab (510) extending from the exterior surface, a tube (440) containing the UAV (400), the tube (440) including a tab stop (515) configured to controllably hinder travel of the AV tab (510) past the tab stop (515), and a pair of opposing tab guides (700, 705) configured to position the AV tab (510) for travel over the tab stop (515).

Heavy inert gas insulation layer(s) are provided for containers configured to contain components that include an energetic material. The heavy inert gas insulation layer delays desensitization or inhibits premature reaction of the energetic material due to high external temperatures. The layers may be formed in hollow walls of the container itself or as inserts that are attached to the container. An inert gas fills a sealed void space in the walls or the insert. The inert gas has a density of at least 1.5 Kg/m.sup.3 and a thermal conductivity (Tcond_gas) of no greater than two-thirds of a thermal conductivity of air (Tcond_air) to form the heavy inert gas insulation layer. The inert gas may be Argon, Krypton, Xenon or a synthetic gas and is suitably held at a pressure of 760 Torr (1 atmosphere) or greater at sea level.
