"Current status[edit]

Listed as part of the National Historic Fleet, HMS Victory has been the flagship of the First Sea Lord since October 2012. Prior to this, she was the flagship of the Second Sea Lord.[75][76] She is the oldest commissioned warship in the world[Note 1] and attracts around 350,000 visitors per year in her role as a museum ship.[77] The current and 100th commanding officer is Lieutenant Commander Rod Strathern Royal Navy, who assumed command in September 2011.[78]

HMS Victory, officially, has a surprisingly large crew complement, though visitors are unlikely to see any naval personnel. It is a legacy of naval legislation that all naval ratings and officers must be assigned to a ship[79] (which may include a shore establishment – still regarded as Her Majesty's Ships by the navy). Any navy person allocated to work in a non-HMS location (such as the Ministry of Defence in London) is recorded as being a member of the crew of HMS Victory"
