According to the Federation of American Scientists, an organization that assesses nuclear weapon stockpiles,
in 2013, Russia possessed an estimated 8,500 total nuclear warheads of which 1,800 were strategically operational.[2] The organization also claims that the U.S. had an estimated total 7,700 nuclear warheads of which 1,950 were strategically operational.[1] Other sources however say that the U.S. has more nuclear warheads and the actual numbers remain a subject of estimations and ongoing constant discussion depending on their respective source. The figures are, by necessity, only estimates because "the exact number of nuclear weapons in each country's possession is a closely held national secret."[1] In addition to nuclear weapons, Russia declared an arsenal of 39,967 tons of chemical weapons in 1997,[3] of which 57% have been destroyed.[4][5] The Soviet Union ratified the Geneva Protocol on April 5, 1928 with reservations. The reservations were later dropped on January 18, 2001. Russia is also party to the Biological Weapons Convention and the Chemical Weapons Convention. The Soviet Union had a peak stockpile of 45,000 nuclear warheads in 1988.[6] It is estimated that from 1949 to 1991 the Soviet Union produced approximately 55,000 nuclear warheads.
