Nuclear Stockpile Update

The United States and Russia's strategic stockpiles are edging closer toward the New START levels of 1,550 deployed nuclear warheads with each side fielding just under 1,600 warheads, new data from the State Department shows.

America deployed 45 fewer warheads on its strategic submarines, heavy bombers and intercontinental ballistic missiles in March compared to the previous count in September 2014, according to an April 1 update from the State Department's bureau of arms control, verification and compliance. Russia's stockpile dipped to 1,582 warheads in March, down 61 weapons compared to the last count.

The New Strategic Arms Reduction Treaty, ratified in 2010, would limit each side to 700 deployed delivery vehicles -- not including cruise missiles -- by February 2018.

On March 1, the U.S. declared 785 deployed nuclear-capable submarines, bombers and ICBMs and Russia declared 515. The U.S maintains 113 delivery vehicles in a non-deployed status and Russia has 375 nuclear-capable platforms in its non-deployed inventory.
