Figures released by the U.S. State Department on Monday elaborated on cumulative totals for fielded and non-deployed nuclear-capable delivery vehicles as of the beginning of March.
Under the New START arms control accord, Washington fielded 1,654 strategic warheads, compared to the 1,480 weapons fielded by Russia. The 2011 bilateral treaty requires both nations to reduce their respective stockpiles of deployed strategic warheads to 1,550 by 2018 and to reduce the number of fielded missiles and bombers to 700, with an additional 100 delivery vehicles allowed in reserve.
As of March, the United States had 792 deployed delivery vehicles, in contrast to 492 maintained by Russia. U.S. totals included 449 deployed Minuteman 3 ICBMs; 314 non-deployed Minuteman 3 and Peacekeeper missiles; 232 deployed Trident D-5 submarine-based ballistic missiles; 176 non-deployed D-5 missiles; 111 deployed B-2 and B-52 bomber aircraft; and 24 non-deployed B-2 and B-52 bombers.
President Obama last month invited the Kremlin to new two-way talks on reducing their deployed strategic nuclear arsenals below New START levels to about 1,000 warheads. Russia, though, has signaled it is not ready to participate in more arms cuts if they do not involve other nuclear-weapon nations and so long as a pending dispute over U.S. missile defense plans in Europe remains unresolved.
