Vice Admiral is a naval rank of three star level, equivalent to Lieutenant General in seniority. In the United States Navy, Vice Admirals generally command the numbered fleets around the world that make up the naval components of each of the regional unified commands. Thus, Vice Admirals do not usually have a sea-going command today.
In the Royal Navy the rank of Vice Admiral should be distinguished from the office of Vice Admiral of the United Kingdom, which is an Admiralty position usually held by a full Admiral.
