Why losing a ship named for the state threatened Nazi prestige

Why was Hitler especially concerned about the Royal Navy sinking a ship named Deutschland?

Because losing a ship named for Germany would have been a serious symbolic defeat for a dictatorship whose legitimacy depended heavily on projecting strength.

A question about naming ships America or United States leads to the renaming of Deutschland as Lützow. A dictatorship built around claims of strength and permanence had more to lose if an enemy sank a warship bearing the nation's name. Democratic systems can more readily absorb visible failures, while Soviet political legitimacy rested on different foundations. The same concern helps explain Hitler's reluctance to risk large surface ships and his reaction after German cruisers failed to break through British destroyers at the Battle of the Barents Sea. A later comparison sharpens the scale of the symbolism: Britannia was one of more than seventy British battleships, whereas Deutschland represented one of only a small number of German major surface units.
