Nuclear-weapon endorser: hosts nuclear weapons on its territory

50 U.S. nuclear weapons hosted

Did not participate in TPNW negotiations

Has not yet joined TPNW

Turkey is one of the five NATO states to host US nuclear weapons as part of NATO's nuclear sharing agreement. The Turkish air force is assigned approximately 50 B61 nuclear bombs, which are deployed at Incirlik Air Base.

Turkey has not yet signed or ratified the Treaty on the Prohibition of Nuclear Weapons. It did not participate in the negotiation of the treaty at the United Nations in New York in 2017 and thus did not vote on its adoption. 

Turkey voted against a UN General Assembly resolution in 2019 that welcomed the adoption of the treaty and called upon “all states that have not yet done so to sign, ratify, accept, approve, or accede to the treaty at the earliest possible date”.

On the opening day of the TPNW negotiating conference in 2017, Turkey joined the United States and several other states in protesting the treaty-making process.

In 2016, Turkey voted against the UN General Assembly resolution that established the formal mandate for states to commence the negotiations in 2017 on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

In a “non-paper” sent to NATO members ahead of the vote, the United States “strongly encourage[d]” members, including Turkey, to vote against the resolution, “not to merely abstain”. In addition, it said that, if the treaty negotiations do commence, allies and partners should "refrain from joining them”.
