The Austrian grand admirals were all members of the Imperial family, except for Anton Haus, the commander of the Austro-Hungarian Navy for part of World War I:[citation needed] In Bourbon Restoration France, the rank was an honorific one equivalent to that of marshal in the French Army.

[citation needed] In the Imperial German Navy, and later in the Kriegsmarine, the rank Großadmiral was the equivalent of a British admiral of the fleet or a United States fleet admiral; as a five-star rank (OF-10).

It was established primarily to honour Paolo Thaon di Revel, who had been head of the Italian Regia Marina during World War I — he was the only person to be awarded the rank.

[citation needed] In 1967 the rank of Grand Admiral of Peru (Spanish: Gran Almirante del Perú) was awarded posthumously to Miguel Grau Seminario and is equivalent to the army rank of Grand Marshal of Peru.

It is awarded by the Grand National Assembly of Turkey to persons who are holding the rank of admiral and displayed distinguished merit in wartime.
