Abstract: A rapidly deployable protective and structural cover system comprising a frame structure and at least one multilayered flexible cover which is comprised of a flexible cover sheeting and a structural netting. The flexible cover sheeting has a plurality of eyelets arranged over the surface area of the flexible cover sheeting. The cover sheeting is attached at a selected plurality of eyelets to the structural netting at the intersections of horizontal and vertical members or strands of the structural netting. The frame structure is preferably comprised of steel cables attachable at the ends thereof to a rigid support structure; turnbuckles to tension the cables. The multilayered flexible cover is removably attachable along edges of the structural netting to the frame and to the cables.
