The US State Department on Monday revealed the size of the US nuclear arsenal, explaining that it means to continue to abide by the New START nuclear disarmament treaty and urging Russia – which suspended its participation in it earlier this year – to do the same.

As of March 1, the U.S. had a total of 662 intercontinental ballistic missiles deployed — including submarine-launched missiles and strategic bombers — with 1,419 nuclear warheads and 800 launchers, a State Department press release listed.

“The US calls on Russia to abide by its legal obligations and fully comply with the New START treaty and the stabilization, transparency and verification measures it contains,” the statement said.

Russia suspended its membership of the treaty in February in retaliation for Western military aid to Ukraine. Her decision was roundly condemned by Western governments.

The New START treaty, signed in 2010, is the latest bilateral agreement on nuclear disarmament between the Russians and the Americans. Moscow had already announced in early August that it had suspended planned inspections of its military facilities.

New START limited the nuclear arsenals of the two states, the world’s largest, to a maximum of 1,550 deployed nuclear warheads each, in other words reducing them by nearly 30 percent compared to 2002, when the previous limits were agreed. It also limited the number of launchers and strategic bombers to a maximum of 800.

The treaty provided for verifications of the arsenals, mutually. Inspections have been suspended due to the novel coronavirus pandemic. The government of the current US President Joe Biden made an effort to restart, in vain.
