Vehicles worth more than £30,000 were stolen and more than £20,000 of damage was caused after thieves broke into Southdown Gliding Club in Cootham.
Between 8.30pm on Wednesday June 4 and 8.30pm on Thursday June 5, intruders cut wire fencing and smashed locks to enter aircraft hangars at the club in Pulborough Road.
They stole three buggies that were used by club members to get around the airfield.
To get to the buggies the thieves moved some of the gliders, causing more than £20,000 of damage in the process to their wings and rudders.
Two of the vehicles were John Dere Gator buggies and one was a Kawasaki buggy.
PCSO Louisa Hull said: “The intruders have caused a considerable amount of damage to get to the vehicles, including wrecking fencing, locks and security systems.
“The damage to the gliders is particularly upsetting to the members of the club as they are needed for their activities.
“The buggies that were stolen are very distinctive and are easily identifiable to someone who sees them.
“If you see them, are offered them for sale or hear of some for sale please contact us immediately.”
