In 1948, the U.S. Army Transportation Corps developed the "Transporter", a rigid, corrugated steel container, able to carry . It was long, wide, and high, with double doors on one end, was mounted on skids, and had lifting rings on the top four corners.
After proving successful in Korea, the Transporter was developed into the Container Express (CONEX) box system in late 1952. Based on the Transporter, the size and capacity of the Conex were about the same, but the system was made ''modular'', by the addition of a smaller, half-size unit of long, wide and high.][Development of Containerization // J. van Ham, J.

The term "CONEX" remains in common use in the US military to refer to the similar but larger ISO-standard shipping containers.
