Why British submarine successes faded from public memory

Why are Royal Navy submarine achievements in World War II often played down?

They were celebrated at the time but later overshadowed by German, American, and Cold War Soviet submarine narratives.

British submarine successes, especially those of U-class boats in the Mediterranean, were publicized during the war. Later popular memory centered more heavily on German U-boats and the American Pacific campaign. The Cold War then recast submarines chiefly as a Soviet threat. Those successive narratives displaced the Royal Navy's wartime record from public attention. The forgetting reflects a change in cultural emphasis rather than evidence that contemporaries ignored the achievements.
