A Lancaster Bomber will make a fly-past on the Saturday
Croome Park is to celebrate the 70th anniversary of the formation of RAF Defford, near Pershore.
The park was requisitioned to form part of a new airfield in 1940, and was used by the Telecommunications Flying Unit during World War II.
A range of wartime recipes can be sampled at the 1940s canteen, in the restored former military hospital.
The event runs from 1100 to 1600 BST, on Saturday, 17 and Sunday, 18 July, and normal admission prices apply.
Other attractions during the weekend event include a Lancaster bomber flypast, 1940s vehicles, re-enactments and a family spy trail.
The Malvern Hills District Brass Band will be playing wartime classics, at the Temple Greenhouse on Saturday, 17 July, including Glen Miller and other music with an aviation theme, such as Magnificent Men in their Flying Machines, Aces High and 633 Squadron.
House and Visitor Services Manager, Amy Forster, said: "We will be bringing the 1940s back to life by showing visitors some of the memories people had of that period and of the war.
"Some of our visitors will remember that time, and we hope they will share their memories with us, but it will also be a fun day out for people of all ages, with plenty to see and do."
The RAF buildings at Croome, now owned by the National Trust, were originally the Sick Quarters for the base and included an airmen's recovery ward, de-contamination chamber and surgical block.
Original features, such as hand-painted signs on the walls, have been retained during the restoration.
