Upton was a mooring-out station for anti-submarine patrol non-rigid airships from Polegate. This airfield was sited among woodland to the north of Upton Country Park and saw significant activity in the final months of World War One. Peacetime brought swift closure as with all other similar supportive airfields engaged in this role.

The following organisations are either based at, use and/or have at least potentially significant connections with the airfield (as at 30/11/2018):
