How did containerization affect military and commercial sea transport?

Containerization, the method of transporting freight in standardized, sealed boxes, revolutionized both commercial and military sea transport by enabling rapid loading and unloading of cargo.12

Impact on Commercial Shipping

Beginning in the 1960s, containerization became a dominant force in commercial ocean shipping. The development of specialized container ships allowed for faster, more frequent trips by minimizing time spent in port. Because containers can be seamlessly transferred between trucks, railroads, and ships, this system significantly reduced the costs and complexities associated with handling uncontainerized cargo.13

Impact on Military Logistics

In the context of military logistics, containerization significantly influenced ship design and the stowage of irregularly shaped freight. While military sea lift during the post-1945 period continued to rely on traditional vessels, the integration of containerization allowed for more efficient management of supplies. This complemented other specialized maritime developments, such as roll-on-roll-off capabilities, which were adapted from World War II landing craft to facilitate the rapid discharge of vehicles and equipment without the need for traditional hoisting.2
