In the Royal Navy, the fleet flagship is, in practice, the warship designated as the fleet's most prestigious vessel, currently HMS Queen Elizabeth.
In the modern era, the fleet flagship has usually been an aircraft carrier, but that changed in 2010 with the assignment of HMS Albion. The flag was transferred to HMS Bulwark in 2011 and HMS Ocean in June 2015,[1] then to HMS Albion in 2018.[2] Finally, the flag reverted to an aircraft carrier when HMS Queen Elizabeth took up her position in January 2021.[3]
