Full Description

The structure is situated in a private field to the west of the B1363 at 53°59'29.01"N & 1° 5'23.72"W. It has been identified variously in the past as a Bunker, Storage Bunker, Taxiway Structure or Blast Bunker but is in fact a Type B Fighter Dispersal Pen (small) FSW4513. It is located off a surviving stub of Perry Track (perimeter track) that leads to the east end of the former east –west runway of RAF Clifton Moor.

These pens were constructed to allow for the safe dispersal around the airfield of the resident North American P51 Mustangs or Curtis Tomahawk Mk11s of 169 Army Co-operation Sqn and 613 Sqn RAF. These units moved into RAF Clifton Moor in December 1942. Originally these structures would have been arranged around the perimeter circuit of the airfield to protect parked aircraft from air attack, as took place at Clifton Moor during the Luftwaffe’s Baedeker raids on York. Today however, this is the sole example to have survived the development of the site. The structure consists of three traversed arms of earthen banks and dwarf brick wall arranged in the standard Type ‘B’ pattern. To the rear of the central arm a pre-cast concrete shelter provides protection for 25 personnel.

Additional defences were sometimes added to these pens to protect them from ground attack. These could take the form of permanent loop-holed brick walls at the end of the outer arms and slit trenches to the rear as seen at RAF Culmhead in Churchstanton in the Blackdown Hills of Somerset. The type of defensive asset deployed varied from station to station and from pen to pen. Whilst no permanent brick defensive positions were present at this site a number of hollows visible in the grassland surrounding the pen were observed, and these could be indicative of the presence of backfilled slit trenches.

The distance between the tip of the central pier and the end of an outer arm was approximately 23m (or 76ft), from the tip of the central pier to the rear of the pan was 23m (76ft), and from tip of the central pier to the rear of the earthen bank was approximately 34m (110ft). These proportions meant that each bay of the dispersal could accommodate one single engine fighter such as a Mustang or one small twin engine aircraft such as a Bristol Blenheim. Larger Type B dispersals were capable of supporting a pair of aircraft per bay.

As was the norm on the Type B an emergency exit was positioned to the rear of the dispersal. This could be positioned to the rear of either the left or right hand bays, and in this instance it was placed to the left.
The structure is in an excellent state of preservation. The dwarf revetment walls are intact as is the vaulted roof of the 25 person shelter. The interior is free from damage and graffiti. The earthen banks are complete and the concrete floor of the bays is intact as is approximately 330m of Perry Track running from the field boundary to the south, past the dispersal and onwards to the eastern end of the east – west aligned runway, upon which now sits a farmhouse and associated agricultural sheds. The only noticeable damage was the absence of a course of soldier bricks above the left hand entrance to the emergency shelter.
