Under the New START Treaty, the United States and the Russian Federation are obligated to exchange data on treaty-accountable items twice a year. Regrettably, the Russian Federation announced a unilateral and unjustified purported suspension of the Treaty on February 28, 2023.  Subsequently, the Russian Federation did not fulfill its obligation to provide updated data in March 2023 and is not implementing other key provisions of the treaty.

As a lawful countermeasure in response to the Russian Federation’s violation of its New START Treaty obligations, the United States did not provide its March data update to Russia.  In the interest of transparency and the U.S. commitment to responsible nuclear conduct, the United States is voluntarily releasing aggregate data for its nuclear forces covered by the New START Treaty in this Fact Sheet.  This data is current as of March 1, 2023.  The United States calls on the Russian Federation to return to full compliance with the New START Treaty and all the stabilizing transparency and verification measures contained within it.
