The panels have facesheets (98) sandwiching one or more core portions and adjacent dense packs oriented in an axial direction. The box structure (12) further has a plurality of spars (40) . Each spar has a web and web attachments and has a spar length in the axial direction. The plurality of spars (40) are connected to the panels with the web attachments located at the dense packs. The facesheets (98) are configured to carry primarily torsion and pressure loads in shear and no significant axial loads. The dense packs are configured to carry all significant box bending in axial tension and compression loads.
