Competition limited interwar Anglo-American design sharing

Outside limited cases, British and American naval constructors observed one another more often than they exchanged complete warship plans.

Question

Did the Royal Navy and United States Navy share ship and submarine plans during the interwar period?

Short answer

Not usually; they exchanged observers and occasional assistance, but their design organizations remained competitive and largely separate.

Notes

The Royal Navy and United States Navy exchanged few complete ship or submarine plans during the interwar period. Each service occasionally sent personnel to advise or observe the other. Those contacts operated alongside a competitive relationship between British naval constructors and the American Bureau of Ships. The result was professional awareness and selective learning rather than a fully integrated design partnership.
