HRH Prince Michael of Kent, GCVO, has attended a rededication ceremony of HMS King Alfred in Portsmouth.
The Prince was attending in his role as Commodore-in-Chief of the Maritime Reserve.
The event marked the culmination of a major refurbishment programme that turned the historic Semaphore tower and surrounding buildings into a first-class training centre within HMNB Portsmouth.
It includes a new drill shed, gym, messes and a wardroom overlooking the harbour.
Watch: HMS Queen Elizabeth's artisan Trafalgar Day tribute.
There is also a new virtual reality training suite enabling the reserves to acquaint themselves with the various classes of Royal Navy vessels.
Music was provided by the Bands of HM Royal Marines Portsmouth and a Queen's Colour Party formed of Royal Naval Reserve personnel presented a Royal Salute for the Queen's cousin.
Eighteen-year-old recruit Katie Stocks, the youngest member of HMS King Alfred, got to cut the rededication cake with Prince Michael.
