Why postwar British warship exports depended on politics

How could Britain have improved postwar warship exports, and were design or wartime lessons the main problem?

Politics was the largest constraint, outweighing the design and experience factors raised in the question.

Politics is the dominant explanation for Britain's weaker postwar warship exports. Design flexibility and whether wartime experience was fully absorbed still matter to the product offered. Buyers, financing, and contract access, however, were shaped primarily by relationships between states. Export performance therefore cannot be read as a simple technical verdict on British designs.
