English: Many of DOD’s items, such as Strykers, high-mobility multipurpose wheeled vehicles, and mine resistant ambush protected vehicles, will not fit in the standard 96-inch-wide container; they require a 102-inch-wide container. The SBS enables container vessels to transport 102-inch containers in a more space- and cost-efficient manner. To allow stacking of 102-inch containers atop 96-inch containers, SBS beams are placed athwart a layer of 96-inch-wide containers. Twist locks secure the beams to the 96-inch containers, and similar twist locks secure the 102-inch containers to the beams, which are placed side by side. Items too large for the 102-inch container can be placed into a CONTRAIL. A CONTRAIL is an easy-to-load and easy-to-handle heavy-duty platform that enables over-sized and over-height equipment to be placed in a container-like envelope. CONTRAILs can be 10, 12, 14, and 16 feet wide and 40, 45, and 48 feet long. The 40-foot CONTRAIL was designed to stow below decks. All others can be stowed on deck using SBS beams. Most military equipment will fit in the standard 12-foot by 40-foot CONTRAIL. Vehicles are driven into the CONTRAIL using a built-in ramp. Once the vehicle is secured, the CONTRAIL is loaded aboard the ship using standard gantry cranes. With collapsible end posts, the CONTRAILs can be folded when empty for compact storage.
