Sea-Land Vietnam Container Service

Sea-Land Vietnam Container Service began in 1967, when Malcom McLean's Sea-Land won a U.S. military contract to carry supplies in containers to Cam Ranh Bay, easing a badly congested war supply chain.

1967 Cam Ranh Bay, South Vietnam

What happened and why it matters

The Vietnam contract proved containers could fix a broken supply chain and, almost by accident, opened Asia to container trade with the United States. Military ports in South Vietnam were jammed with ships waiting to unload loose cargo, and Sea-Land reinforced the pier and built its own terminal at Cam Ranh Bay at its own cost and risk. Ships returning empty began calling in Japan to carry exports back to the United States, and services to Hong Kong, Taiwan and South Korea followed. That backhaul logic still drives ocean pricing: rates on a lane depend on how full ships are in each direction, which is why Asia to U.S. rates differ so much from the return leg.
