Nuclear sharing is a concept in NATO's policy of nuclear deterrence, which allows member countries without nuclear weapons of their own to participate in the planning for the use of nuclear weapons by NATO. In particular, it provides for involvement of the armed forces of those countries in delivering nuclear weapons in the event of their use.

Contents

As part of nuclear sharing, the participating countries carry out consultations and make common decisions on nuclear weapons policy, maintain technical equipment (notably nuclear-capable airplanes) required for the use of nuclear weapons and store nuclear weapons on their territory. In case of war, the United States has told NATO allies the Non-Proliferation Treaty (NPT) would no longer be controlling. [1]

Of the three nuclear powers in NATO (France, the United Kingdom and the United States), only the United States is known to have provided weapons for nuclear sharing. As of November 2009, Belgium, Germany, Italy, the Netherlands and Turkey have been hosting U.S. nuclear weapons as part of NATO's nuclear sharing policy. [3] [4] Canada hosted weapons under the control of the North American Aerospace Defense Command (NORAD), rather than NATO, until 1984, and Greece until 2001. [3] [5] [6] The United Kingdom also received U.S. tactical nuclear weapons such as nuclear artillery and Lance missiles until 1992, even though the UK is a nuclear-weapon state in its own right; these were mainly deployed in Germany.

In peacetime, the nuclear weapons stored in non-nuclear countries are guarded by United States Air Force (USAF) personnel and previously, some nuclear artillery and missile systems were guarded by United States Army (USA) personnel; the Permissive Action Link codes required for arming them remain under American control. In case of war, the weapons are to be mounted on the participating countries' warplanes. The weapons are under custody and control of USAF Munitions Support Squadrons co-located on NATO main operating bases who work together with the host nation forces. [3]

As of 2021, 100 tactical B61 nuclear bombs are believed to be deployed in Europe under the nuclear sharing arrangement. [2] The weapons are stored within a vault in hardened aircraft shelters, using the USAF WS3 Weapon Storage and Security System. The delivery warplanes used are General Dynamics F-16 Fighting Falcons (F-16s) and Panavia Tornados. [7]

Historically, the shared nuclear weapon delivery systems were not restricted to bombs. Greece used Nike-Hercules Missiles as well as A-7 Corsair II attack aircraft. Canada had Bomarc nuclear-armed anti-aircraft missiles, Honest John surface-to-surface missiles and the AIR-2 Genie nuclear-armed air-to-air rocket, as well as tactical nuclear bombs for the CF-104 fighter. [8] PGM-19 Jupiter medium-range ballistic missiles were shared with Italian air force units and Turkish units with U.S. dual key systems to enable the warheads. [9] PGM-17 Thor intermediate-range ballistic missiles were forward deployed to the UK with RAF crews. [10] [11] An extended version of nuclear sharing, the NATO Multilateral Force was a plan to equip NATO surface ships of the member states with UGM-27 Polaris missiles, but the UK ended up purchasing the Polaris missiles and using its own warheads, and the plan to equip NATO surface ships was abandoned. [12] After the Soviet Union collapsed, the nuclear weapon types shared within NATO were reduced to tactical nuclear bombs deployed by Dual-Capable Aircraft (DCA). [3] According to the press, Eastern European Member States of NATO have resisted the withdrawal of the shared nuclear bombs from Europe, fearing it would show a weakening of U.S. commitment to defend Europe against Russia. [13]

In Italy, B61 bombs are stored at the Ghedi Air Base and at the Aviano Air Base. According to the former Italian President Francesco Cossiga, Italy's role in a planned retaliation consisted in striking with those nuclear weapons Czechoslovakia and Hungary had the Warsaw Pact waged nuclear war against NATO. [14] [15] He acknowledged the presence of U.S. nuclear weapons in Italy, and speculated about the possible presence of British and French nuclear weapons. [16]

The only German nuclear base is located in Büchel Air Base, near the border with Luxembourg. The base has 11 Protective Aircraft Shelters (PAS) equipped with WS3 Vaults for storage of nuclear weapons, each with a maximum capacity of 44 B61 nuclear bombs. There are 20 B61 bombs stored on the base for delivery by German PA-200 Tornado IDS bombers of the JaBoG 33 squadron. Germany's Tornado IDS aircraft are due to be retired by the end of 2024; while 2010 and 2018 assessments questioned what nuclear sharing role, if any, Germany would then retain, [3] [17] in 2020 Germany announced that it would buy 30 Boeing F/A-18E/F Super Hornets to replace the Tornado in its nuclear sharing role. [18] The Super Hornet was not yet certified for the B61 bomb, but Dan Gillian, head of Boeing's Super Hornet program, had previously stated his optimism about achieving this certification in a timely manner. [19] In 2022, against the backdrop of the Russian invasion of Ukraine, the Super Hornet order was cancelled and Germany instead chose to order 35 Lockheed Martin F-35 jets for nuclear sharing use. [20] [21]

On 10 June 2013, former Dutch prime minister Ruud Lubbers confirmed the existence of 22 shared nuclear bombs at Volkel Air Base. [22] This was inadvertently confirmed again in June 2019 when a public draft report to the NATO Parliamentary Assembly was discovered to reference the existence of US nuclear weapons at Volkel, as well as locations in Belgium, Italy, Germany, and Turkey. A new version of the report was released on 11 July 2019 without reference to the locations of the weapons. [23]

In 2017 due to an increasingly unstable relationship between the United States and Turkey it was suggested that the United States consider removing 50 tactical nuclear weapons stored under American control at the Incirlik Air Base in Turkey. [24] [25] [26] [27] [28] [29] [30] The presence of US nuclear weapons in Turkey gained increased public attention in October 2019 with the deterioration of relations between the two nations after the Turkish military incursion into Syria. [31] [32] [33] [34] [35]

In 2022, after the Russian invasion of Ukraine, reports appeared about the possible inclusion of Poland in the nuclear sharing policy, with president Andrzej Duda calling the country's lack of nuclear weapons a "problem" and saying that it was in talks with the United States about the possibility of nuclear sharing. [36] In June 2023, then-prime minister Mateusz Morawiecki declared Poland's interest in hosting nuclear weapons under the policy, citing the reported deployment of Russian nuclear weapons to its Kaliningrad region and Belarus, while National Security Bureau head Jacek Siewiera said the country was interested in certifying its upcoming F-35A fleet as being capable of delivering B61 bombs. [37] In April 2024, president Duda said that Poland was "ready" to host nuclear weapons and had been discussing the matter with the United States government for "some time". [38] The current Polish prime minister, Donald Tusk, said that he wanted to speak with Duda to understand the intention behind the statement and that he wanted Poland to "be safe and well-armed, but [he] would also like any initiatives to be very well prepared by the people responsible for them and for all [Poles] to be convinced that this is what [they] want." [39] In May, foreign minister Radosław Sikorski accused president Duda of failing to consult with him on this and other major foreign policy announcements and said that he had "asked the president privately and publicly not to discuss such delicate and secret matters in public, because it [did] not help Poland"; he also said that the previous Polish government had been told that the idea of Poland being involved with nuclear sharing was "not on the table". [40]

Preparations for Russia–Belarus nuclear weapons sharing

On 27 February 2022, shortly after the 2022 Russian invasion of Ukraine, Belarusians voted in a referendum to repeal the post-Soviet Constitutional prohibition on basing of nuclear weapons in Belarus. [41] At a meeting on 25 June 2022, Russian President Putin and President of Belarus Lukashenko agreed the deployment of Russian short-range nuclear-capable missiles. The deployment of nuclear warheads for nuclear sharing would require a further decision, possibly after a number of years, and might be tied to future NATO decisions. [42]

Russia will supply Belarus with nuclear-capable Iskander-M missile systems. [42] Both conventional and nuclear versions of the missile would be provided to the Belarusians. [43] Additionally, Putin said that he would facilitate the modifications necessary for Belarusian Su-25 bombers to carry nuclear missiles. [44]

Potential nuclear sharing between Pakistan and Saudi Arabia

It is common belief among foreign officials that Saudi Arabia and Pakistan have an understanding in which Pakistan would supply Saudi Arabia with warheads if security in the Persian Gulf was threatened. A Western official told The Times that Saudi Arabia could have the nuclear warheads in a matter of days of approaching Pakistan. Pakistan's ambassador to Saudi Arabia, Muhammed Naeem Khan, was quoted as saying, "Pakistan considers the security of Saudi Arabia not just as a diplomatic or an internal matter but as a personal matter." Naeem also said that the Saudi leadership considered Pakistan and Saudi Arabia to be one country and that any threat to Saudi Arabia is also a threat to Pakistan. [45] Other vendors were also likely to enter into a bidding war if Riyadh indicated that it was seeking nuclear warheads. Both Saudi Arabia and Pakistan have denied the existence of any such agreement. [46] Western intelligence sources have told The Guardian that "the Saudi monarchy paid for up to 60% of the Pakistani nuclear programme, and in return has the option to buy a small nuclear arsenal ('five to six warheads') off the shelf". [47] Saudi Arabia has potential dual-purpose delivery infrastructure, including Tornado IDS and F-15S fighter bombers and improved Chinese CSS-2 intermediate range ballistic missiles with accuracy sufficient for nuclear warheads but delivered with high explosive warheads. [48] [49]

In November 2013, a variety of sources told BBC Newsnight that Saudi Arabia was able to obtain nuclear weapons from Pakistan at will. The new-report further stated, according to western experts, it was alleged that Pakistan's defense sector, including its missile and defense labs, had received plentiful financial assistance from Saudi Arabia. [50] Gary Samore, an adviser to Barack Obama, said, "I do think that the Saudis believe that they have some understanding with Pakistan that, in extremis, they would have claim to acquire nuclear weapons from Pakistan." [51] Amos Yadlin, formerly head of Israeli military intelligence, said "They already paid for the bomb, they will go to Pakistan and bring what they need to bring." [51]

Response

According to the US based think-tank, the Center for Strategic and International Studies, the BBC report on possible nuclear sharing between Pakistan and Saudi Arabia is partially incorrect. There is no indication of the validity or credibility of the BBC's sources, and the article fails to expand on what essentially constitutes an unverified lead. Furthermore, if Pakistan were to transfer nuclear warheads onto Saudi soil, it is highly unlikely that either nation would face any international repercussions if both nations were to follow strict nuclear sharing guidelines like those of NATO. [52] A research paper produced by the British House of Commons Defence Select Committee states that as long as current NATO nuclear sharing arrangements remain in place, the NATO states would have few valid grounds for complaint if such a transfer were to occur. [53]

Nuclear Non-Proliferation Treaty considerations

Both the Non-Aligned Movement and critics within NATO believe that NATO's nuclear sharing violates Articles I and II of the Nuclear Non-Proliferation Treaty (NPT), which prohibit the transfer and the acceptance of direct or indirect control, respectively, over nuclear weapons.[ citation needed ]

The United States insists that its forces control the weapons and that no transfer of the nuclear bombs or control over them is intended "unless and until a decision were made to go to war, at which the NPT would no longer be controlling", so there is no breach of the NPT. [54] [55] However, the pilots and other staff of the "non-nuclear" NATO countries practice handling and delivering the US nuclear bombs, and non-US warplanes have been adapted to deliver US nuclear bombs which involved the transfer of some technical nuclear weapons information. Even if the US argument is considered legally correct, some argue such peacetime operations appear to contravene both the objective and the spirit of the NPT. [53] Essentially, all preparations for waging nuclear war have already been made by supposedly non-nuclear weapon states.

There are concerns that this arrangement undermines, and possibly contravenes, Articles I and II of the NPT. According to US lawyers, the transfer of control is legal because, on the outbreak of "general war", the NPT has failed in its purpose and can be regarded as no longer in controlling force. This arrangement was conceived in the early to mid-1960s to contain proliferation. It is arguable that several European nations including Germany were persuaded not to become nuclear states themselves because of the NATO nuclear umbrella. However, a nuclear sharing arrangement that may have had some logic in the pre-NPT and cold war world is now a source of weakening for the NPT, as it offers a rationale to other states to pursue a similar programme. NATO's nuclear sharing programme could now be used as an excuse by China, Pakistan or any other nuclear-armed nation to establish a similar arrangement. Imagine if China were to offer such an arrangement to persuade North Korea to give up its nuclear ambitions. Or if Pakistan were to undertake nuclear sharing with Saudi Arabia or Iran. Such developments would be perceived as a threat to security in North Asia or the Middle East, and even as a direct threat to NATO. Yet, while the NATO arrangements remain in place, NATO members would have few valid grounds for complaint. The Committee should recommend the immediate termination of NATO nuclear sharing arrangements. [53]

Evidence submitted to House of Commons Defence Committee (UK Parliament), The future of NATO and European defence (4 March 2008) (p. Ev 80, paras. 50–51)

At the time the NPT was being negotiated, the NATO nuclear sharing agreements were secret. These agreements were disclosed to some of the states, including the Soviet Union, negotiating the treaty along with the NATO arguments for not treating them as proliferation. Most of the states that signed the NPT in 1968 would not have known about these agreements and interpretations at that time. [56]

The Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT, is an international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy, and to further the goal of achieving nuclear disarmament and general and complete disarmament. Between 1965 and 1968, the treaty was negotiated by the Eighteen Nation Committee on Disarmament, a United Nations-sponsored organization based in Geneva, Switzerland.

<span class="mw-page-title-main">Nuclear proliferation</span> Spread of nuclear weapons

Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as "Nuclear Weapon States" by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare, de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states.

<span class="mw-page-title-main">United States and weapons of mass destruction</span>

The United States is known to have possessed three types of weapons of mass destruction: nuclear, chemical, and biological weapons. As the country that invented nuclear weapons, the U.S. is the only country to have used nuclear weapons on another country, when it detonated two atomic bombs over two Japanese cities of Hiroshima and Nagasaki during World War II. It had secretly developed the earliest form of the atomic weapon during the 1940s under the title "Manhattan Project". The United States pioneered the development of both the nuclear fission and hydrogen bombs. It was the world's first and only nuclear power for four years, from 1945 until 1949, when the Soviet Union produced its own nuclear weapon. The United States has the second-largest number of nuclear weapons in the world, after the Russian Federation.

<span class="mw-page-title-main">China and weapons of mass destruction</span>

The People's Republic of China has developed and possesses weapons of mass destruction, including chemical and nuclear weapons. The first of China's nuclear weapons tests took place in 1964, and its first hydrogen bomb test occurred in 1966 at Lop Nur. Tests continued until 1996, when the country signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT), but did not ratify it. China acceded to the Biological Weapons Convention (BWC) in 1984 and ratified the Chemical Weapons Convention (CWC) in 1997. Since 2020, China has been wielding a nuclear triad, alongside four other countries.

<span class="mw-page-title-main">India and weapons of mass destruction</span>

India possesses nuclear weapons and previously developed chemical weapons. Although India has not released any official statements about the size of its nuclear arsenal, recent estimates suggest that India has 172 nuclear weapons and has produced enough weapons-grade plutonium for up to 200 nuclear weapons. In 1999, India was estimated to have 800 kilograms (1,800 lb) of separated reactor-grade plutonium, with a total amount of 8,300 kilograms (18,300 lb) of civilian plutonium, enough for approximately 1,000 nuclear weapons. India has conducted nuclear weapons tests in a pair of series namely Pokhran I and Pokhran II.

<span class="mw-page-title-main">Pakistan and weapons of mass destruction</span>

Pakistan is one of nine states that possess nuclear weapons. Pakistan began developing nuclear weapons in January 1972 under Prime Minister Zulfikar Ali Bhutto, who delegated the program to the Chairman of the Pakistan Atomic Energy Commission (PAEC) Munir Ahmad Khan with a commitment to having the device ready by the end of 1976. Since PAEC, which consisted of over twenty laboratories and projects under reactor physicist Munir Ahmad Khan, was falling behind schedule and having considerable difficulty producing fissile material, Abdul Qadeer Khan, a metallurgist working on centrifuge enrichment for Urenco, joined the program at the behest of the Bhutto administration by the end of 1974. Producing fissile material was pivotal to the Kahuta Project's success and thus to Pakistan obtaining the capability to detonate a nuclear weapon by the end of 1984.

<span class="mw-page-title-main">Tactical nuclear weapon</span> Nuclear weapon designed for use on a battlefield

A tactical nuclear weapon (TNW) or non-strategic nuclear weapon (NSNW) is a nuclear weapon that is designed to be used on a battlefield in military situations, mostly with friendly forces in proximity and perhaps even on contested friendly territory. Generally smaller in explosive power, they are defined in contrast to strategic nuclear weapons, which are designed mostly to be targeted at the enemy interior far away from the war front against military bases, cities, towns, arms industries, and other hardened or larger-area targets to damage the enemy's ability to wage war. As of 2024, no tactical nuclear weapons have ever been used in combat.

<span class="mw-page-title-main">Strategic nuclear weapon</span> Nuclear weapons used on strategic targets outside of battlefields

A strategic nuclear weapon (SNW) is a nuclear weapon that is designed to be used on targets often in settled territory far from the battlefield as part of a strategic plan, such as military bases, military command centers, arms industries, transportation, economic, and energy infrastructure, and countervalue targets such areas such as cities and towns. It is in contrast to a tactical nuclear weapon, which is designed for use in battle as part of an attack with and often near friendly conventional forces, possibly on contested friendly territory. As of 2024, strategic nuclear weapons have been used twice in the 1945 United States bombings of Hiroshima and Nagasaki.

About 100 of these (versions −3 and −4) are thought to be deployed at six bases in five European countries: Aviano and Ghedi in Italy; Büchel in Germany; Incirlik in Turkey; Kleine Brogel in Belgium; and Volkel in the Netherlands. This number has declined since 2009 partly due to reduction of operational storage capacity at Aviano and Incirlik (Kristensen 2015, 2019c). ... Concerns were raised about the security of the nuclear weapons at the Incirlik base during the failed coup attempt in Turkey in July 2016, and the chairman of the Senate Foreign Relations Subcommittee for Europe stated in September 2020 that "our presence, quite honestly, in Turkey is certainly threatened," and further noted that "we don't know what's going to happen to Incirlik" (Gehrke 2020). Despite rumors in late 2017 that the weapons had been "quietly removed" (Hammond 2017), reports in 2019 that US officials had reviewed emergency nuclear weapons evacuation plans (Sanger 2019) indicated that that there were still weapons present at the base. The numbers appear to have been reduced, however, from up to 50 to approximately 20.
