Russia has 1,643 nuclear missiles ready to launch - one more than the US - according to an official State Department report. Both countries have been upgrading their active nuclear arsenals since the outbreak of the Ukrainian conflict, reports GHN based on RT.
The US report is based on official figures exchanged between the two countries as part of the New START disarmament treaty, and includes missiles deployed before September 1. The numbers show a significant increase from March, when data showed that Washington had a capacity of 1,585 payloads, and Moscow 1,512.
The current figures are in violation of the New START treaty, signed in 2010 by Barack Obama and then-President Dmitry Medvedev, during the short-lived reset in relations between the two states, which prescribe a limit of 1,550 deployed warheads.
Overall, the authoritative Center for Arms Control and Non-Proliferation believes Moscow has more than 8,000 warheads, and Washington over 7,000, although not all of them can be allocated to efficient delivery systems.
Russia recently announced a planned overhaul of its entire nuclear arsenal by 2020, as part of a wider rearmament program that has been budgeted at $700 billion.
Although Moscow has not provided a detailed breakdown of how it achieved the upgrade of nuclear capacity over the past months, experts on both sides of the Atlantic have speculated that the rise has been due to the armament of one - or possibly two - Borei-class nuclear submarines.
