Temporary harbours turn a beachhead into a supply base

Can a modern force assemble a temporary harbour after an amphibious landing?

Yes. Modular pontoons, Mexeflotes, bridging systems, and flexible fuel-storage arrangements can create a practical unloading and sustainment base.

Temporary harbours remain a practical part of amphibious planning. British Mexeflote pontoons and Army bridging systems can be combined into unloading and access infrastructure. Flexible fuel bladders can even be stored underwater, where water pressure assists delivery, cooling reduces risk, and concealment offers some protection. A landing force needs this port-like supply system after the opening assault.
