The New START Treaty is a nuclear arms reduction agreement between the United States and the Russian Federation, which was signed on Apr. 10, 2010.
The treaty restricts the number of deployed strategic nuclear warheads to 1,550. It also limits the number of deployed and non-deployed intercontinental ballistic missile (ICBM) launchers, heavy bombers equipped, and submarine-launched ballistic missile (SLBM) launchers for nuclear armaments to 800. Furthermore, the treaty’s duration is ten years and will expire on February 5, 2021. The involved parties can agree to extend the treaty for no more than five years.
On January 21, 2021, the White House press secretary Jen Psaki said in a briefing said that the Biden administration would seek a five-year extension to the New START arms control treaty with Russia, which expires in February.
