Thor missile site at former RAF North Luffenham

The Thor missile site at the former RAF North Luffenham is a Grade II* listed site featuring reinforced concrete bases, structures, and infrastructure. It is located in an isolated area at the far eastern point of the airfield, accessible from the airfield perimeter track. The site includes three launch emplacements arranged in a typical broadly triangular configuration within a compound, with parts of the inner fence-line still visible to the east, south, and south-west of the emplacements.

Each of the three emplacements retains its blast walls, launcher erector mountings, and the footings for fuel dump pits on either side of the erector. Most of the rails leading to the causeway and the end of the shelter are still present. The fuel pipe conduits from the pits to the launcher are intact, and the steel fuel pipes surrounding the launcher mounting are visible, along with platforms for the short-range theodolites.

All emplacements have their theodolite shed platforms, but only the central and eastern emplacements have partially standing theodolite sheds and the lower portions of the concrete long-range theodolite pillars.

The Surveillance and Inspection Building is a single-storey, flat-roofed structure made from pre-fabricated concrete slabs, which has been extended to the north by a taller structure covered in corrugated metal. The interior of this building was not inspected.
