RAF/USAF Alconbury

I don’t profess to be any kind of expert on airfields, not even close, but they do interest me, especially Cold War airfields. The following is a ‘cut up’ of material from a variety of locations mingled in with some of my own words. Its certainly not a definitive history on Alconbury, more of an overview to accompany the pictures.

Thanks for looking 🙂

RAF Bomber Command use (1939-1941)
In September 1939, RAF Upwood squadrons were given operational training roles and Alconbury became RAF Wyton’s satellite under No. 2 Group, Squadron Nos. 12, 40 and 139. These squadrons were frequently deployed to Alconbury, No. 139 being the first to be actually stationed there. Squadrons 15 and 40 converted from Battles to Bristol Blenheim bombers. No. 15 Squadron took up residence on 14 April 1940, when additional requisitioned accommodation was available. It flew its first raid of the war on 10 May against a German occupied airfield near Rotterdam.

In May 1942, RAF Alconbury was allocated to the United States Army Air Force:

The Cold War, Spy Planes & Operation Desert Storm
In 1959 with the Cold War hotting up (lame humour..), the 10th Tactical Reconnaissance Wing arrived at Alconbury and over the coming years flew many reconnaissance, electronic warfare and ‘Aggressor Support’ missions.

The Strategic Air Command arrived at Alconbury on 1 October 1982 when the 17th Reconnaissance Wing was activated, bringing with them the U2 and later the TR-1 Spy Plane. These assets required major remodelling of the airfield including Ready Sheds, 13 extra wide Hardened Aircraft Shelters, a Photographic Interpretation Centre and a Nuclear Hardened Command Post/Avionics Suite for the TR-1 spyplanes known only as Building 210 (later nicknamed Magic Mountain).
 
After the fall of the Berlin Wall and the threat of the Cold War vanishing there were rumours that RAF Alconbury would be closed down but then in August 1990, Iraq invaded Kuwait.
Some of the first aircraft to be sent into the Gulf were three TR-1A’s from Alconbury’s 17th Reconnaissance Wing and 23 A-10’s from the 10th Tactical Fighter Wing (511th Tactical Fighter Squadron) were deployed to Saudi Arabia for combat operations.

The 511th TFS A-10s flew no fewer than 1700 combat missions during Operation Desert Storm and played an important part in wreaking havoc on Iraqi tank forces, Scud missiles and other ground positions during the conflict.

In recent years things have wound down considerably and in 1995 the USAF returned the base to the MoD (but retaining the Base Support Area under USAF control). The USAF 423d Air Base Squadron and USAF 501st Combat Support Wing still operate from Alconbury.

Ok, long overdue, some full on Cold War action for you…

In the 1950’s Skunkworks (Lockheed Advanced Development Projects) created a single engined, very high-altitude reconnaissance aircraft to be used in the Cold War to help determine Soviet capabilities and intentions. Elements of previous Lockheed designs such as the Lockheed F-104 Starfighter were incorporated to build what became the Lockheed U-2 Spy Plane (and later the TR-1). The first live flight was in August 1955 at Area 51 in Nevada and soon a variety of intelligences packages were developed for use with the plane that could be switched around depending on the mission (Interchangeable nose sections were fitted with large format cameras, radar and other cutting edge surveillance equipment). They flew so high that the pilot had to wear a space suit and breath bottled oxygen.

When the USAAF 17th Reconnaissance Wing was activated the 95th Reconnaissance Squadron was formed at RAF Alconbury bringing with them a fleet of TR-1 Spy planes. Building 210 was the Avionics and Photography Interpretation Centre for the TR-1/U2 Spy plane taking two years to build at a cost of $39 million and was later given the nickname Magic Mountain. The building was linked to various other US bases and also to the Strategic Air Command in Omaha, Nebraska.

Inside the stainless steel lined entrance corridor are a series of large rooms with raised access flooring for computer cabling. Building 210 has its own power plant, closed air conditioning, decontamination chambers, water supply and sewage systems. A Positive Air Pressure system was used to prevent any fallout or poisonous gas getting inside the facility. The bunker is on two floors and built of steel and reinforced concrete, sitting on a bed of gravel and giant ‘spring coils’ allowing the structure to shift during an attack and absorbing the impact. Allegedly it could withstand a direct hit from a nuclear bomb.

The political situation changed in 1989 with the fall of the Berlin Wall and within six months of opening Magic Mountain was obsolete. By July 1991 the USAAF 17th Reconnaissance Wing was deactivated and by 1993 the entire base was handed back to the MoD.

On this visit I could not gain access to the subterranean bunker itself so you will have to make do with the few photo’s I could get, I will however be going back so watch this space…
