Then on the on 20 August an actual Spitfire and a Hurricane will perform a commemorative fly-over.
In-house caterers Sodexo have joined the celebrations my creating a seven course tasting menu inspired by Winston Churchill.
"[Churchill] was passionate about food and, despite there being a war on, he insisted on having three course meals as often as possible. When he dined in the War Rooms, his own personal cook would come down to the bunker to cook for him," said head chef Kevin Gaffney.
"Churchill's favourite food was British and French cuisine and our celebration menu reflects this."
The seven course costs £70 per person for a minimum of ten people.
