On May 24, 2002, Presidents George W. Bush and Vladimir Putin signed the Strategic Offensive Reduction Treaty (SORT), under which the United States and Russia reduced their strategic arsenals to 1,700-2,200 heads. The warhead border came into force and expired on the same day, December 31, 2012. Although the two sides have not agreed on specific counting rules, The Bush administration stated that the United States would reduce only warheads used on strategic active-duty delivery vehicles (i.e. “operational” warheads) and would not count warheads removed from service and placed in warehouses or warheads on delivery vehicles that are obsolete or repaired. The limits of the agreement are similar to those provided for START III, but the contract did not require the destruction of delivery vehicles, as START I and II did, nor the destruction of warheads, as planned for START III. The treaty was approved by the Senate and Duma and came into force on 1 June 2003. SORT was replaced by New START on February 5, 2011. New START In response to an ICAN appeal, more than eight hundred parliamentarians around the world supported a ban treaty, called on “all national governments to negotiate a treaty banning nuclear weapons and leading to their total eradication” and calling it “necessary, feasible and more urgent.” Among the countries they represent were members of existing nuclear-weapon-free zones and NATO countries. Of the five permanent nuclear members of the UN Security Council, the United Kingdom was the only one with the support of elected representatives for this initiative.  The Air Force`s current acquisition plan for LRSO provides for approximately 1,000 new nuclear missiles, about twice the size of the existing ALCMs fleet. According to the service, the planned purchase of 1,000 missiles includes far more missiles than planned to arm and deploy nuclear warheads.
For GJ 2019, the NNSA requested $654 million for the W80-4, making it the second most expensive nuclear warhead next to the B61-12. In addition, the Air Force requested $615 million for the development of the LRSO rocket. Rosatom also builds several floating nuclear power plants.  The completion of the first, called Academik Lomonosov, was considerably delayed by financial difficulties and legal proceedings between Rosenergoatom and the construction of the ship, Baltiiskiy zavod.  However, the ship was tested in 2016 and began the first leg of its voyage to Pevek, on Russia`s Arctic coast, in April 2018.  Once commissioned, the plant will replace electricity generated by the Bilibino nuclear power plant and the Chaunsky thermal power plant. Power and heat are expected to begin in October 2019.  The Treaty on the Prohibition of Nuclear Weapons prohibits the use, possession, development, experimentation, use and transfer of nuclear weapons under international law.
Russia also possesses a large number of non-strategic or tactical nuclear weapons, most of which most analysts believe are linked to air, naval and ground air defence and ABM forces.  Russia has never disclosed the number and nature of weapons in its non-strategic nuclear arsenal. Presidential nuclear initiatives (NIPs) from 1991 to 1992 resulted in substantial reductions in non-strategic nuclear deployments by the United States and Russia, but did not require Washington or Moscow to exchange information on their respective stockpiles or include an implementation verification mechanism.
