Three Type C Fighter Pens

The site comprises three Type C fighter pens, laid out in a line along the airfield's perimeter track, spaced 55 metres apart. Each pen has three arms arranged in a curvilinear 'E' shape, enclosing a concrete hardstanding designed to accommodate two aircraft, one on either side of the central arm. The arms appear as turf-covered earth mounds, bordered by low brick walls along the sides of the central mound and on the inside edge of the outer mound. The central arm is approximately 23.8 metres long, 6.4 metres wide, and 2.2 metres high. The curved outer mound is roughly 3 metres high and 12 metres wide; its northern slopes are wider and longer due to the natural topography.

Within the outer mound, on either side of the central arm, are brick-lined entrances leading to pre-cast concrete Stanton air-raid shelters, which could hold up to 25 personnel. A third entrance, originally an emergency exit, is located at the rear of the outer curved mound. The hardstandings are paved with concrete slabs, with some areas patched with tarmac. The eastern hardstanding reveals four round holes, thought to be where aircraft were tied down.

Extending from the main perimeter track, midway between the western and central fighter pens, is an F-shaped taxiing area with concrete tracks. This area originally led to three Blister hangars, which have since been removed. Concrete footpaths link the eastern and central fighter pens to the area beyond. A small road provided access for vehicles to the flight offices. Raised platforms, rectangular and circular in shape, mark the former locations of sleeping shelters, flight offices, squadron offices, a parachute store, a drying room, and a latrine.
