The Battle of Britain will be marked at Newhaven Fort with a flypast by the Spitfire of the Battle of Britain Memorial Flight on Sunday September 15.
There will be live music from The Swingtime Sweethearts and Seaford Silver Band, as well as dancing from Studio Tempo.
And there will be the first visit of Puttin’ on the Blitz barbershop quartet.
A vintage hair and make-up salon will be amongst the attractions, while visitors will also be able to enjoy military vehicles and living history displays.
The day of nostalgia and commemoration will mark The Battle of Britain, the German air force’s attempt to gain air superiority over the RAF from July to September 1940 in the UK.
Their failure was one of the turning points of World War Two and prevented Germany from invading Britain.
Newhaven Fort was built in the 1860s but went on to play a role during World War II.
The German invasion plan, Operation Sea Lion, included a landing by the German 9th Army between Brighton and Beachy Head.
Its 9th Division was to come ashore in Seaford Bay to capture Newhaven Port.
