Vice-Admiral: Rank, History, and Insignia of the Royal Navy
In the hierarchical structure of the United Kingdom's maritime forces, the Vice-Admiral (VAdm) serves as a critical senior leadership role. As a flag officer—a term used for officers entitled to fly a personal flag—the Vice-Admiral occupies a high-level command position within the Royal Navy, bridging the gap between the Rear Admiral and the full Admiral.
Under the standardized NATO rank system, the Vice-Admiral is designated as rank code OF-8. This ensures seamless interoperability and clear chains of command when the Royal Navy operates alongside international allies.

The Evolution of the Rank
The Royal Navy has utilized the rank of Vice-Admiral since at least the 16th century. Historically, when a fleet was deployed, the Vice-Admiral was positioned in the van (the leading portion of the fleet), where they served as the primary deputy to the Admiral.
The rank's origins are linked to the position of Lieutenant of the Admiralty, which existed between 1546 and 1564. This officer acted as the secretary to the Lord Admiral of England. While the specific title of Lieutenant of the Admiralty lapsed in 1876, it was later revived by King Edward VII in 1901.
Until 1864, the Royal Navy was organized into coloured squadrons. An officer's career path and the specific command flags they flew were determined by which squadron they belonged to, leading to titles such as Vice-Admiral of the Red, White, or Blue.
Rank Insignia and Identification
Vice-Admirals are identified by specific visual markers on their uniforms and through the flags they fly while in command.
Uniform Insignia
The rank is displayed on the sleeve lace as a broad band accompanied by two narrower bands. On shoulder boards, the rank is designated by stars. Since 2001, the Royal Navy has officially designated this as a three-star rank, increasing the number of stars on the shoulder board to three to align with modern standards.
The Personal Flag
As a flag officer, a Vice-Admiral is entitled to fly a personal command flag. This flag consists of a St George's cross defaced with a red disc located in the hoist (the part of the flag nearest the flagpole).
