New START (Strategic Arms Reduction Treaty) (Russian: СНВ-III, SNV-III) is a nuclear arms reduction treaty between the United States and the Russian Federation with the formal name of Measures for the Further Reduction and Limitation of Strategic Offensive Arms. It was signed on 8 April 2010 in Prague, and, after ratification, entered into force on 5 February 2011. It is expected to last at least until 2021.
New START replaced the Treaty of Moscow (SORT), which was due to expire in December 2012. Its name is a follow-up to the START I treaty, which expired in December 2009, the proposed START II treaty, which never entered into force, and the START III treaty, for which negotiations were never concluded.
Under terms of the treaty, the number of strategic nuclear missile launchers will be reduced by half. A new inspection and verification regime will be established, replacing the SORT mechanism. It does not limit the number of operationally inactive that remain in the high thousands in both the Russian and American inventories.
According to a Reuters report on February 9, 2017, in US President Donald Trump's first 60-minute telephone call with Russian President Vladimir Putin, Putin inquired about extending New START. President Trump denounced the treaty, claiming that it favored Russia and was "one of several bad deals negotiated by the Obama administration".
Under the terms of the treaty, the number of strategic nuclear missile launchers will be reduced by half. The treaty limits the number of deployed strategic nuclear warheads to 1,550, which is down nearly two-thirds from the original START treaty, as well as 10% lower than the deployed strategic warhead limit of the 2002 Moscow Treaty. The total number of deployed warheads, however, could exceed the 1,550 limit by a few hundred because per bomber only one warhead is counted regardless of how many it actually carries. It will also limit the number of deployed and non-deployed inter-continental ballistic missile (ICBM) launchers, submarine-launched ballistic missile (SLBM) launchers, and heavy bombers equipped for nuclear armaments to 800. The number of deployed ICBMs, SLBMs, and heavy bombers equipped for nuclear armaments is limited to 700. The treaty allows for satellite and remote monitoring, as well as 18 on-site inspections per year to verify limits.
