Three Type C Fighter Pens

Laid out in a line along the perimeter track of the airfield, 55 metres apart, each fighter pen consists of three arms arranged in the shape of a curvilinear 'E', enclosing a concrete hardstanding, for two aircraft, one either side of the central arm. The arms are evident as turf covered, earth mounds, revetted by low brick walls on either side of the central mound and on the inner edge of the outer mound. The central arm measures approximately 23.8 metres long, 6.4 metres wide and 2.2 metres high. The outer mound is curved and is approximately 3 metres high and 12 metres wide. As the natural topography drops down to the north, the northern slopes of the outer mound are considerably longer and wider than the internal slopes. On either side of the central arm of the fighter pens and set within the curved outer mound, is a brick-lined entrance which gives access to a pre-cast, concrete, Stanton type air-raid shelter set within the central section of the outer mound. The shelter could accommodate up to 25 men during an attack. The rear of the outer curved mound contains a third entrance, originally an emergency exit. The hardstandings are surfaced in concrete slabs and some small areas have been patched with tarmac. The eastern hardstanding has four round holes which are believed to have been the positions of aircraft tie-down points.

Outside the footprint of the fighter pens, an F-shaped taxiing area consisting of a series of concrete tracks extends from the main perimeter track, midway between the western and the central fighter pen. Originally, three Blister hangars were located at the end of the tracks, but these are now gone. Concrete footpaths run between the eastern and central fighter pen to support buildings, now lost, beyond the fighter pens. A short road allowed vehicle access to the flight offices. Rectangular and circular slightly raised platforms represent the remains of a sleeping shelter for each fighter pen, flight offices, squadron offices, a parachute store, a drying room and a latrine.
