HER Majesty The Queen sent a message to troops at RAF Uxbridge to mark her condolences at the closure of the famous base.
In the letter to Squadron Leader Gareth Rossiter, from her equerry Wing Commander Calame, the value of the base in the Battle of Britain was noted.
It reads: "Her Majesty thought it was most appropriate that the day will be marked by a parade of The Queen's Colour Squadron and the Royal Air Force Central Band, and as importantly will be attended by members of the local community, who have offered the Station such stalwart attention since 1918.
"Her Majesty was interested to hear that, in this anniversary year, the historic Number 11 Group Operations Rooms Bunker has been listed and will be preserved as a Royal Air Force asset.
"Hopefully, the facility will continue as a permanent reminder of those who fought and won the Battle of Britain.
"Her Majesty hopes that the relocation to Royal Air Force Northolt will continue to progress well and wishes all personnel at Uxbridge best wishes for the future."
The base has been visited in the past by Royals, with King George V first attending the site in 1918.
King George VI also attended the base to oversee operations in 1940.
War time Prime Minister Winston Churchill also attended the base countless times during the Battle of Britain.
