NATO Non-Nuclear Weapon State
Sharing US Nuclear Weapons
Two German PA-200 Tornados,
Estimate Arsenal Size
- 10-20 U.S. non-strategic gravity B-61 warheads at the Büchel Air Base 
- Reliable documents indicate that an estimated 130 U.S. nuclear weapons at the Ramstein Air Base were removed between 2001 and 2005. 
- Non-strategic warheads: B-61-3, B-61-4 
- Delivery Aircraft: German PA-200 Tornados
- The U.S. National Nuclear Security Administration (NNSA) is currently modernizing the non-strategic warheads deployed in Europe. NNSA is refurbishing and replacing components of the aging B-61-3 and B-61-4 warheads, converting them into the updated B61-12 model. Under NNSA’s B61-12 Life Extension Plan, the updated warheads will enter full production in 2020 and be deployed by 2024. 
Destructive Power 
- B-61-3: maximum yield of 170 kilotons
- B-61-4: 45 kilotons
Nuclear Weapons Policies
- 1999 NATO Strategic Concept confirms commitment to deploying nuclear weapons in Europe to maintain the "minimum level sufficient to preserve peace and stability."  In 2010 NATO reasserted that it would be a nuclear alliance while nuclear weapons continue to exist. 
- While NATO continues to reaffirm the importance of deploying U.S. nuclear weapons in Europe, disagreements among member states on this issue have become more pronounced since the German government expressed support for the withdrawal of U.S. nuclear weapons from Germany and Europe in October 2009.  In 2010 Germany, along with other NATO nations, restated its request for the U.S. to remove nuclear weapons stationed in European NATO member states. 
- With the withdrawal of 130 U.S. nuclear weapons from the Ramstein Air Base, the number of U.S. nuclear weapons in Germany was reduced to only 20. 
- The Deterrence and Defense Posture Review adopted at the May 2012 NATO Summit in Chicago states that "the Alliance's nuclear force posture currently meets the criteria for an effective deterrence and defense posture." Therefore, some experts argue that the scheduled nuclear modernization contradicts this concept. 
- On 5 September 2014 NATO asserted the centrality of nuclear deterrence to the security of NATO members, with U.S. nuclear capabilities playing a key role in this strategy. While stating that a situation in which a nuclear weapon would be detonated is highly unlikely, NATO declared that current relations with Russia have halted cooperative disarmament efforts. U.S. nuclear weapons are therefore likely to remain in Germany and other NATO nuclear-sharing countries. 
- NATO's 2016 Warsaw Summit Communique criticized Russia's annexation of Crimea, destabilization of Ukraine, and aggressive rhetoric. NATO went on to reiterate the role of nuclear weapons as a deterrent. On the issue of disarmament, NATO stated that disarmament efforts must take into account the current security situation, and that it is regrettable that the prospects for disarmament are "not favorable today." 
- Germany supports the Australia-led Humanitarian Initiative.  While the alternative Austria-led Initiative maintains that regardless of circumstance nuclear weapons should not be detonated, the Australia-led initiative has not made that declaration. 
- Germany is a member of the Non-Proliferation and Disarmament Initiative (NPDI), a group of non-nuclear weapon states dedicated to disarmament, nonproliferation and peaceful nuclear activities as outlined in the NPT and the 2010 NPT Review Conference.
