The closing preview explains how national infrastructure shaped carrier design. The US Navy had to consider the Panama Canal, which made beam a distinctive restriction on its carriers. The Royal Navy's concern was the Suez Canal, where draft mattered more in the period discussed. Japan faced neither canal constraint in quite the same way for Pacific operations, yet its ships still had to fit what domestic infrastructure could construct and sustain. Carrier dimensions therefore depended on the routes, yards, and support systems available to each navy.

Canals and infrastructure impose different carrier-design limits
A preview of later carrier videos contrasts the US Navy's Panama Canal beam limit, the Royal Navy's Suez draft concern, and Japan's construction infrastructure.
