The Vice-Admiral of the Blue was a senior rank of the Royal Navy of the United Kingdom, immediately outranked by the rank Vice-Admiral of the White (see order of precedence below). Royal Navy officers currently holding the ranks of commodore, rear admiral, vice admiral and admiral of the fleet are sometimes considered generically to be admirals. From 1688 to 1805 this rank was in order of precedence sixth; after 1805 it was the seventh. In 1864 it was abolished as a promotional rank.
