An armored panel construction for a shelter to defeat ballistic fragment and thermal radiation threats comprises an inner structural panel of aluminum alloy sheets bonded to a honeycomb core and an outer face panel of an aramid fiber fabric in a multi-ply resin matrix laminate. The face panel is in a specific spaced relationship to the inner structural panel such that the energy of an impacting projectile is distributed over a large area and the face panel is allowed to flex inwardly in the absorption of such energy.

A configuration for a lightweight and portable shelter having wall and roof panels armored against ballistic fragment and thermal radiation threats comprises in combination: vertical and horizontal aluminum alloy corner extrusions defining a cove angle at an inward extent and forming a skeleton framework of the shelter; inner structural panels supported in the corner extrusions, said structural panels comprising inward and outward facing aluminum alloy sheets bonded to a lightweight honeycomb core, the inward facing sheet mechanically fastened to the cove angle in the corner extrusion; an extruded aluminum alloy cap angle mechanically fastened to the outward facing sheet of the inner structural panel and covering the corner extrusions forming the framework; and an outer face panel comprised of a multi-ply laminate of at least seven plies of an aramid fiber fabric in a resin matrix, said face panel overlapping and mechanically fastened to the cap angle extrusion such that a gap of at least 1.5 mm (0.6 inch) is defined as between the face panel and the outward facing aluminum sheet of the inner structural panel.
