The Atomic Weapons Establishment (AWE) is a United Kingdom Ministry of Defence research facility responsible for the design, manufacture and support of warheads for the UK's nuclear weapons. It is the successor to the Atomic Weapons Research Establishment (AWRE) with its main site on the former RAF Aldermaston and has major facilities at Burghfield, Blacknest and RNAD Coulport.
AWE plc, responsible for the day-to-day operations of AWE, is owned by the Ministry of Defence and operated as a non-departmental public body.
Until June 2021, AWE plc was owned by a consortium of Jacobs Engineering Group, Lockheed Martin UK, and Serco through AWE Management Ltd, which held a 25‑year contract (until March 2025) to operate AWE, although all the sites remained owned by the Government of the United Kingdom which had a golden share in AWE plc. [1] In November 2020, it was announced that the Ministry of Defence had triggered a contractual break point and would take ownership of AWE Plc in July 2021. [2] [3]
The establishment is the final destination for the Campaign for Nuclear Disarmament's Aldermaston Marches march from Trafalgar Square, London. The first Aldermaston March was conceived by the Direct Action Committee and took place in 1958.
The British nuclear weapons programme, then operating under the project name 'High Explosive Research' within the Ministry of Supply, established operations on 1 April 1950 at the former RAF Aldermaston airfield. [4] The airfield was constructed in World War II and had been used by the Royal Air Force and the United States's Eighth and Ninth Air Force as a troop carrier (C‑47) group base, and was assigned USAAF station No 467. In 1952, the High Explosive Research project was renamed the Atomic Weapons Research Establishment (AWRE), with William Penney appointed as the first director. [5]
In 1954 AWRE was transferred to the newly created United Kingdom Atomic Energy Authority (UKAEA). In 1971, under the provisions of the Atomic Energy Authority Act 1971, the production activities of UKAEA were transferred to the newly created British Nuclear Fuels Ltd. (BNFL).
In 1973 AWRE was transferred to the Procurement Executive of the Ministry of Defence, see Atomic Energy Authority (Weapons Group) Act 1973. Parts of AWRE's weapons production processes were carried out at two Royal Ordnance Factories (ROFs): ROF Burghfield and ROF Cardiff. In 1984 these two ROFs were separated from the other ROFs, which were then formed into a government-owned defence company, Royal Ordnance plc and was privatised in 1987. ROF Burghfield and ROF Cardiff remained within the Procurement Executive and came under the control of AWRE.
In 1987, AWRE was combined with ROF Burghfield and ROF Cardiff to form the Atomic Weapons Establishment (AWE), [4] these sites being renamed AWE Burghfield and AWE Cardiff (the latter was closed in 1997).
It remained with the Ministry of Defence, Procurement Executive. However, in 1989, the UK government announced its intention to find a suitable private company to run AWE under a Government Owned/Contractor Operated (GO‑CO) arrangement.
In 1993 the government awarded a contract to Hunting-BRAE, a consortium of Hunting Engineering, Brown and Root and AEA Technology. During Hunting-BRAE's management AWE decommissioned the RAFs WE177 freefall nuclear bomb. In 1998 the company suffered two prosecutions for safety breaches, one for discharge of tritium into a nearby stream [6] and another for an incident where two workers inhaled plutonium. [7]
In 1999 Hunting-BRAE lost the contract to AWE Management Ltd (AWE ML), a consortium of BNFL, Lockheed Martin and Serco. AWE ML's subsidiary, AWE plc, assumed responsibility for the operation of all AWE sites on 1 April 2000. This was not full privatisation as the Ministry of Defence continued to own all the AWE sites as well as a golden share in AWE plc.
Critics pointed out that BNFL and Lockheed Martin did not have perfect safety records either. BNFL suffered embarrassing revelations of falsified quality checks in nuclear fuels and Lockheed was the subject of scathing reports on the operation of US nuclear facilities. Lockheed's failings included safety concerns at the Y-12 facility at Oak Ridge, Tennessee, an American weapons plant similar in certain ways to Aldermaston.
In December 2008, the BNFL share in AWE Management Ltd was sold to Jacobs Engineering Group, an American engineering services company. [8]
Since about 2013 the Office for Nuclear Regulation (ONR) has given both AWE sites enhanced regulatory attention due to "safety and compliance concerns, and the continued undertaking of operations in ageing facilities due to delays to the delivery of modern standard replacement facilities." The ONR anticipated AWE would move back to normal regulatory attention in 2021 after the new facilities are completed. [9]
Scientists at AWE were involved in testing for radioactive poison after the poisoning of Alexander Litvinenko. No gamma rays were detected; however, the BBC reported that a scientist at AWE, who had worked on Britain's early atomic bomb programme decades before, recognised a small spike at an energy of 803 kilo-electron volts (keV) as the gamma ray signal from polonium-210, a critical component of early nuclear bombs, which led to the correct diagnosis. Further tests using spectroscopy designed to detect alpha radiation confirmed the result. [10]
In July 2015 the Office for Nuclear Regulation issued an improvement notice to AWE demanding that it demonstrate that it has a long-term strategy for managing Higher Active radioactive Waste in order to reduce the risk to the public and its employees. [11]
In 2011 a project named MENSA to construct a new warhead assembly and disassembly facility at Burghfield had been approved, to be completed in 2017 at a cost £734 million. In 2020, a National Audit Office report found that costs had increased by £1.07 billion to £1.8 billion and completion date had slipped to 2023. Construction was begun before design had been finalised and risk was not shared with contractors, so they were not incentivised to control costs. [12] [13]
In November 2020, it was announced that the Ministry of Defence had triggered a contractual break point and would take ownership of AWE Plc in July 2021. [2] [3] Sir John Manzoni was announced as chair-designate, and he formally took on the role of chair of the board on 1 July 2021. [14]
AWE is tasked to help the United Kingdom maintain a credible and effective minimum nuclear deterrent:
A significant programme of investment took place over the three-year period from 2005 to 2008, of about £350 million per year, to provide assurance that the existing Trident missile warhead is reliable and safe throughout its intended in-service life. The new facilities and extra supporting infrastructure are required in the absence of live nuclear testing no longer allowed under the Comprehensive Test Ban Treaty. [15]
AWE co-operates with the Los Alamos National Laboratory in the United States and other American nuclear weapons laboratories in carrying out subcritical nuclear tests at the Nevada underground test site to obtain scientific data to maintain the safety and reliability of nuclear weapons. Subcritical tests are not banned by the Comprehensive Test Ban Treaty on nuclear weapons. The most recent test took place in February 2006. [16]
The cost of decommissioning AWE facilities when they become redundant, including nuclear waste disposal, was estimated at £3.4 billion in 2005. [17]
On 3 August 2010 a fire broke out in the explosives processing area at AWE Aldermaston, resulting in the evacuation of nearby residents from their homes. [18] Investigations by a local newspaper revealed that from 1 April 2000, to 5 August 2011, 158 fires broke out at AWE sites, with the fire brigade being called out to deal with alarms on average four times a week over this period. [19] The Health and Safety Executive took the decision to prosecute AWE plc on three charges relating to health and safety after their investigation into the fire in 2010, the first hearing in this case being held on 6 August 2012. [20] On 16 May 2013 AWE pleaded guilty to a single offence contrary to the Health and Safety at Work Act 1974. [21]
In 2013 a whistleblower alerted the authorities to lapses in security caused by misconduct among police officers guarding the base. The MoD said that security was never threatened, but MoD police considered it a "critical" incident. Six officers were dismissed for gross misconduct and 25 resigned. [22]
Formerly part of the Ministry of Defence, AWE Blacknest has, for over 40 years, specialised in forensic seismology, researching techniques to distinguish the seismic signals generated by underground nuclear explosions from those generated by earthquakes. It is approximately 1 mile west of the main AWE site.
Blacknest's main function is to develop and maintain expertise in using seismic techniques to detect and identify underground explosions. This expertise and the techniques have been used in the past to provide assessments for the UK government on nuclear explosions carried out by other countries. The expertise is to be used as part of Britain's contribution to the Comprehensive Nuclear-Test-Ban Treaty which was signed in 1996, but which, as of 2015, has not come into force.
Chevaline was a system to improve the penetrability of the warheads used by the British Polaris nuclear weapons system. Devised as an answer to the improved Soviet anti-ballistic missile defences around Moscow, the system increased the probability that at least one warhead would penetrate Moscow's anti-ballistic missile (ABM) defences, something which the Royal Navy's earlier UGM-27 Polaris re-entry vehicles (RVs) were thought to be unlikely to do.
The United Kingdom Atomic Energy Authority is a UK government research organisation responsible for the development of fusion energy. It is an executive non-departmental public body of the Department for Energy Security and Net Zero (DESNZ).
The WE.177, originally styled as WE 177, and sometimes simply as WE177, was a series of tactical and strategic nuclear weapons with which the Royal Navy (RN) and the Royal Air Force (RAF) were equipped. It was the primary air-dropped nuclear weapon in the United Kingdom from the late 1960s into the 1990s.
Chapelcross nuclear power station is a former Magnox nuclear power station undergoing decommissioning. It is located in Annan in Dumfries and Galloway in southwest Scotland, and was in operation from 1959 to 2004. It was the sister plant to the Calder Hall nuclear power station plant in Cumbria, England; both were commissioned and originally operated by the United Kingdom Atomic Energy Authority. The primary purpose of both plants was to produce weapons-grade plutonium for the UK's nuclear weapons programme, but they also generated electrical power for the National Grid. Later in the reactors' lifecycle, as the UK slowed the development of the nuclear deterrent as the cold war came to a close, power production became the primary goal of reactor operation.
In 1952, the United Kingdom became the third country to develop and test nuclear weapons, and is one of the five nuclear-weapon states under the Treaty on the Non-Proliferation of Nuclear Weapons.
Royal Ordnance Factories (ROFs) were munitions factories run by the UK government during and after the Second World War. The three main types of factories were engineering, filling and explosives, and these were dispersed across the country for security reasons. ROFs were the responsibility of the Ministry of Supply and later the Ministry of Defence until privatisation in 1987.
The US–UK Mutual Defense Agreement, or the 1958 UK–US Mutual Defence Agreement, is a bilateral treaty between the United States and the United Kingdom on nuclear weapons co-operation. The treaty's full name is Agreement between the Government of the United States of America and the Government of the United Kingdom of Great Britain and Northern Ireland for Cooperation on the uses of Atomic Energy for Mutual Defense Purposes. It allows the US and the UK to exchange nuclear materials, technology and information. The US has nuclear co-operation agreements with other countries, including France and other NATO countries, but this agreement is by far the most comprehensive. Because of the agreement's strategic value to Britain, Harold Macmillan called it "the Great Prize".
The Special Escort Group (Ministry of Defence Police) or SEG (MDP) are a specialised unit of the Ministry of Defence Police. It is primarily responsible for the movement of all nuclear weapons and Defence Special Nuclear Material within the United Kingdom.
Violet Club was a nuclear weapon deployed by the United Kingdom during the Cold War; the name was chosen in adherence to the Rainbow code system. It was Britain's first operational "high-yield" weapon and was intended to provide an emergency capability until a thermonuclear weapon could be developed from the 1956–1958 Operation Grapple tests. Violet Club was ultimately replaced in service by the Red Snow warhead, derived from the US W28 warhead.
Royal Naval Armaments Depot Coulport, shortened to RNAD Coulport, on Loch Long in Argyll, Scotland, is the storage and loading facility for the nuclear warheads of the United Kingdom's Trident programme.
Defence Nuclear Material Transport Operations refer to the movements of military Defence Nuclear Materials (DNM) within, to and from the United Kingdom. Defence Nuclear Material Transport Operations are also known as DNM Transportation; Defence Nuclear Material in transit; Nuclear movements; and DNM movements.
Trident, also known as the Trident nuclear programme or Trident nuclear deterrent, covers the development, procurement and operation of nuclear weapons in the United Kingdom and their means of delivery. Its purpose as stated by the Ministry of Defence is to "deter the most extreme threats to our national security and way of life, which cannot be done by other means". Trident is an operational system of four Vanguard-class submarines armed with Trident II D-5 ballistic missiles, able to deliver thermonuclear warheads from multiple independently targetable re-entry vehicles (MIRVs). It is operated by the Royal Navy and based at Clyde Naval Base on the west coast of Scotland. At least one submarine is always on patrol to provide a continuous at-sea capability. The missiles are manufactured in the United States, while the warheads are British.
Nuclear history of the United States describes the history of nuclear affairs in the United States whether civilian or military.
A Gravel Gertie is a type of bunker designed to provide containment during the nuclear weapons assembly process, when the plutonium or highly enriched uranium "pit" is mated with the high explosive components and wired into the electronics of the warhead.
Royal Ordnance plc was formed on 2 January 1985 as a public corporation, owning the majority of what until then were the remaining United Kingdom government-owned Royal Ordnance Factories which manufactured explosives, ammunition, small arms including the Lee–Enfield rifle, guns and military vehicles such as tanks. It owned some 16 factories; and employed about 19,000 staff.
Burghfield Brook is a small stream in southern England. It rises in Wokefield Common between the Berkshire villages of Mortimer and Burghfield Common. It is a tributary of Foudry Brook, which it joins near Hartley Court Farm, just to the south of the M4 motorway.
Action AWE is a grassroots activist anti-nuclear weapons campaign/group launched in February 2013. Its aim is to increase and activate public opposition to the UK Trident nuclear weapons system, and depleted uranium warheads manufactured at AWE Burghfield, along with AWE Aldermaston.
Following the success of Operation Grapple in which the United Kingdom became the third nation to acquire thermonuclear weapons after the United States and the Soviet Union, Britain launched negotiations with the US on a treaty under in which both could share information and material to design, test and maintain their nuclear weapons. This effort culminated in the 1958 US–UK Mutual Defence Agreement. One of the results of that treaty was that Britain was allowed to use United States' Nevada Test Site for testing their designs and ideas, and received full support from the personnel there, in exchange for the data "take" from the experiment, a mutual condition. In effect the Nevada Test Site became Britain's test ground, subject only to advance planning and integrating their testing into that of the United States. This resulted in 24 underground tests at the Nevada Test Site from 1958 through the end of nuclear testing in the US in September 1992.
Kate Pyne was an English historian working at the Atomic Weapons Establishment (AWE), Aldermaston. Her work there included the writing of technical history on various aspects of the British nuclear weapons programme from its earliest days to the present time. Prior to taking a degree in Modern History at Queen Mary and Westfield College, University of London, she worked for many years in the aircraft industry.
The Orion Laser Facility is a high power laser facility based at the Atomic Weapons Establishment (AWE) on the former RAF Aldermaston site in the United Kingdom.
