The United States and Russia were each deploying fewer strategic nuclear weapons as of March 1 than they did six months earlier, according to the Department of State’s latest data on the bilateral New START nuclear treaty.
Since the last official State-published tally in September 2019, Russia cut more strategic warheads from its arsenal than the U.S.: 100, compared with three. That left Moscow with 1,326 weapons on deployed long-range missiles and strategic bombers, slightly under Washington’s count of 1,373.
Year over year, the U.S. added eight deployed warheads across those same counted forces, as Russia cut 135.
New START took effect in 2011 and limits to 1,550 the number of strategic nuclear weapons that Washington and Moscow may deploy on a mixture of intercontinental ballistic missiles (ICBM), heavy bomber aircraft, and submarine-launched ballistic missiles (SLBM). Both sides reached that limit in February 2018.
The accord is due to expire next February, but can be extended for up to five years. The countries had yet to begin talks about an extension, at deadline Thursday.
Russia has said it would extend the treaty. The Donald Trump administration continues to press for a new trilateral agreement also involving China, with American officials saying there is still time if needed to extend New START. Critics say Washington is only running out the clock because the Trump administration favors killing the treaty. Beijing has repeatedly said it will not consider participating in a new accord.
The COVID-19 pandemic has, in any case, put some New START activities on hold.
The Wahsington-based Arms Control Association, citing “diplomatic and Congressional sources,” said this week that the U.S. and Russia agreed to suspend on-site inspections of one another’s arsenals until May 1. Likewise, the New START Bilateral Consultative Commission, where the sides hash out the details of treaty compliance, suspended a scheduled March meeting. The sides will now exchange notices that would have passed through the commission via “regular diplomatic channels,” the nongovernmental pro-disarmament group wrote.
Under the pact, the State Department reports a tally of deployed, treaty-covered warheads and launchers, as of the first days of March and September.

New START does not cover tactical and novel nuclear weapons, though President Donald Trump has said he wants a follow-on treaty to address those arms. The former are sometimes called battlefield weapons — relatively smaller nukes that theoretically could be used in relatively low numbers to destroy key adversary weapons, troops, or supporting infrastructure. Strategic weapons, launched in great numbers, are capable of destroying an adversary’s entire military and economic infrastructure, along with much of the population.
Novel weapons are strange devices such as the uncrewed, nuclear-powered, nuclear-armed submersible that Russian President Vladimir Putin has said his country is developing. Also included is Russia’s nuclear-armed, nuclear-powered cruise missile, a test version of which is suspected to have killed several Russians last year.
