Royal Air Force Aldermaston, or more simplyRAF Aldermaston, is a formerRoyal Air Forcestation located 8 miles (13 km) east ofNewbury,Berkshire and 9.8 miles (15.8 km) southwest ofReading, Berkshire,England.
Originally built as anRAF Bomber Command airfield during 1941-1942, Aldermaston was transferred to theUnited States Army Air Forces in August 1942.[1] Placed under the jurisdiction ofEighth Air Force, it was home to severalDouglas C-47 Skytrain Troop Carrier Groups. It was transferred toNinth Air Force in 1943 primarily as a Troop Carrier Command base.[2] Returned to RAF Control at the end of 1945, it was used by Technical Training Command before being placed on Care and Maintenance. In 1946, it was transferred to the Ministry of Civil Aviation and used by BOAC aircraft for training.[1]
Also used by the Ministry of Aircraft Production forSupermarine Spitfire assembly and flight testing, the airfield closed in 1950 and the site became home of the Atomic Weapons Research Establishment (later theAtomic Weapons Establishment) from 1950.[1]

Aldermaston was initially planned as an RAF Bomber Command airfield, being constructed in 1941-1942. RAF 92 Group was programmed to occupy the facility withVickers Wellington bombers. The facility was constructed as a "Class A" bomber airfield with three concrete runways. The main was 1,830m aligned 06/24, with two crosswind secondary runways of 1,280m aligned 11-29 and 17-35.[3] The airfield had an encircling perimeter track with both the pan and loop-type aircraft hardstands for aircraft parking.[3] The technical site was on the south side of the airfield, consisting of various administrative buildings, maintenance shops and four large T-2 hangars.[1]
However, to support theUnited States Army Air Forces (USAAF) Eighth Air Force in August 1942, jurisdiction of Aldermaston was transferred from RAF Bomber Command to the USAAF. The USAAF assigned station No. 467 to the facility.USAAF Station Units assigned to RAF Aldermaston were:[2]
Regular Army Station Units included:
A non-flying facility located about one-half mine north of the airfield. It is a large country house which was purchased from the Keyser family by the British Government at the outbreak of World War II. Taken over by the USAAF, it became the headquarters of theXIX Tactical Air Command (formerly XIX Air Support Command). It was given the designation of AAF-476.[6]

Due to Aldermaston's location in Berkshire, Eighth Air Force decided to use the base to station as a C-47 Troop Carrier base. Upon completion of construction in August, the60th Troop Carrier Group (60th TCG) was transferred from its temporary locations atRAF Chelveston andRAF Podington in East Anglia, which became heavy bomber bases. The operational squadrons of the 60th TCG were:[7]
The unit trained with Army paratroop units during the fall of 1942, preparing for combat operations in North Africa as part of theOperation Torch invasion of French North Africa. It flew its only combat mission on 8 November 1942 when it transported airborne paratroopers from Aldermaston, and dropping them at Oran, Algeria during the early hours of the invasion.[7]
With the successful operation, the group moved toRelizane Airfield, Algeria on 8 November 1942. There, it was transferred to the newTwelfth Air Force where it continued combat operations as part of theMediterranean Theater of Operations until the end of the war.[9]
With the 60th's move to North Africa, the 107th Reconnaissance Squadron,67th Observation Group, was moved to Aldermaston on a temporary basis fromRAF Membury in Berkshire. It flew a mixture of light observationL-4 Grasshopper single engine andDouglas A-20 Havoc two-engine reconnaissance aircraft. It also had severalSupermarine Spitfires. The squadron remained only until 8 January 1943 when it was moved back to Membury.[8]

Replacing the 60th TCG was the315th Troop Carrier Group, which was deployed from theFlorence Army Airfield, South Carolina in December 1942.[9] Also equipped with C-47s, operational squadrons of the group at Aldermaston were:
Prior to its arrival, two of the group's squadrons were reassigned to Twelfth Air Force in North Africa, and the group only had 24 aircraft assigned while at Aldermaston. On 25 May 1943, twenty-one of the 315th's aircraft left forAlgeria to support combat operations in North Africa. Although not participating in the airborne phase of theinvasions of Sicily and Italy, the aircraft did support those operations by transporting supplies in the theater.[9]
With the reassignment ofNinth Air Force from Libya to the United Kingdom in October 1943, the 315th, along with all of the Eighth's Troop Carrier groups were transferred to the Ninth. The remaining components of the 315th TCG were moved toRAF Welford (AAF 474) in Berkshire. Jurisdiction of Aldermaston Airfield was also transferred to the Ninth,[9]
In December 1943 the 15th Tactical Reconnaissance Squadron arrived in England fromKey Field, Mississippi, It was initially assigned directly to Ninth Air Force, but the squadron arrived un-equipped.[8] Ninth Air Force attached the squadron to the67th Reconnaissance Group atRAF Middle Wallop (AAF-449) in late December.[8] At Aldermaston, the squadron received Supermarine Spitfires from the Ministry of Aircraft assembly plant and trained with the aircraft until 1 May, when it was moved toRAF Chilbolton (AAF-404) in Hampshire.[8]
Delays in base construction and equipment delivery from the United States meant that the 370th Fighter Group arrived at Aldermaston in early February 1944 fromBradley Field, Connecticut un-equipped.[9] Upon its arrival, the group expected to receiveRepublic P-47 Thunderbolts, however due to a lack of equipment in the United Kingdom, the unit was instead equipped with available Lockheed P-38 Lightnings.[8] Also, Aldermaston was only a way-station for the unit, as the base was already programmed for Troop Carrier units to support the upcoming invasion of Normandy. After receiving the P-38s, the group was moved toRAF Andover (AAF-106) in Hampshire at the end of February.[9]

With the transfer of the 370th FG, the 434th Troop Carrier Group was moved to Aldermaston from RAF Fulbeck (AAF-488) in Lincolnshire on 3 March 1944.[9] Its operational squadrons were:
The 434th was programmed to drop the101st Airborne Division in preparation for the invasion of northern France, and it was located with the 101st. The 434th was one of the groups trained and designated to deliver gliders on D-Day.As the assigned delivery group for Mission Chicago, the 52 C-47s of the 434th TCG each towed aWaco CG-4A glider to Normandy, losing one aircraft to flak in the darkness. For this, and two follow-up missions with gliders and supplies, the group was later awarded the coveted Distinguished Unit Citation.[10]
After the invasion of France, the mission of the 435th became resupply and casualty evacuation of Allied ground forces on the continent. Supplies transported were, for the most part, critically needed items such as communications equipment and special ammunition[10] In September, the 434th was again assigned the 101st Airborne Division which it transported into the Nazi-Occupied Netherlands as part of Operation Market, the airborne component of Operation Market-Garden.[10] For the balance of 1944, the group returned to conducting resupply and casualty evacuation transport missions.[10]
The 434th remained at Aldermaston until 12 February 1945 when the group moved to anAdvanced Landing Ground (ALG) atMourmelon-le-Grand Airfield (ALG A-80) in France.[9]
With no further USAAF requirement for the station, Aldermaston was returned to the Air Ministry on 15 June 1945.[1]

In July 1943 Vickers erected a large assembly facility and took over Hangar 5 for Supermarine Spitfire production. Components produced in the Southampton area were sent to the facility for assembly and final aircraft production. This was part of the dispersal program aimed at minimizing aircraft production due to the possibly of German bombing raids.[clarification needed][3] It was co-located in the airfield technical site, and used the airfield along with the USAAF for test-flying newly produced aircraft. It remained in operation at Aldermaston until the Royal Air Force received operational control of the facility in 1946.[11]
In 1949,Fairey Aviation used Aldermaston airfield for the first flight of the first prototypeFairey Gannet, serialled VR546, which was built in its factory at Hayes, Middlesex then taken by road to Aldermaston, reassembled and successfully test flown by the company's chief test pilot Gp/Capt R G Slade on 19 September.

The airfield was relinquished to theAir Ministry on 15 June 1945. It was to be the site for a flying school, where more than 1,000 former RAF pilots would be retrained to fly civil aircraft. Many of the buildings were refurbished and improved runway lights were installed.
From 15 June 1945 the following organisations used the airfield:[12]
In 1950 the airfield was taken over by theMinistry of Supply to house theAtomic Weapons Research Establishment (A.W.R.E.).
