Abstract: A shock and vibration resistant structure includes a frame having a plurality of substantially rectangular regions therein. A plurality of modular units are received in the regions. The units have a lower external surface, side external surfaces, and a top external surface. A plurality of shock and vibration isolators extending from portions of the frame toward at least two adjacent external surfaces of the units, isolate the units from shock and vibration. The units are removable and replaceable. An elevator is used to lift the units so that they may be transferred horizontally from the elevator to the frame. Stabilizing members disposed between the units and the frame fall away when the structure is subjected to shock and vibration.
