Under the New START Treaty, the United States and the Russian Federation were required to come within the following central limits on their strategic offensive arms by February 5, 2018, and must remain within the limits thereafter, for the life of the treaty:

  • 700 deployed intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and heavy bombers (HBs);
  • 1,550 warheads on deployed ICBMs and SLBMs and warheads counted for deployed heavy bombers; and
  • 800 deployed and non-deployed ICBM launchers, SLBM launchers, and heavy bombers.

The charts below document U.S. and Russian force levels for delivery vehicles (DVs), launchers, and warheads subject to the treaty, including before the treaty’s central limits came into effect. U.S. and Russian force numbers routinely fluctuate, such as when systems change deployment status due to routine maintenance. The United States assesses Russian forces subject to the treaty have remained below the central limits since they took effect on February 5, 2018.
