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. The treaty limit is 1,550 deployed strategic warheads, with one bomber counted as a single warhead. Both sides reached that limit in February 2018.
New START took effect in 2011 and limits 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). It is due to expire next February, but can be extended for up to five years.
President Donald Trump wants to replace New START with a trilateral arms control agreement that also limits China’s nuclear arsenal, and caps other types of nuclear weapons and launchers. Beijing has repeatedly said it will not consider participating in such an 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.
