Foreign Relations Committee and Senate Armed Services Committee both held hearings on the
treaty. The U.S. Senate gave its advice and consent to ratification on December 22, 2010, by a
vote of 71-26. Both houses of the Russian parliament—the Duma and Federation Council—
approved the treaty in late January 2011, and it entered into force on February 5, 2011, after
Secretary of State Clinton and Foreign Minister Lavrov exchanged the instruments of ratification.
New START provides the parties with seven years to reduce their forces, and will remain in force
for a total of 10 years. It limits each side to no more than 800 deployed and nondeployed ICBM
and SLBM launchers and deployed and nondeployed heavy bombers equipped to carry nuclear
armaments. Within that total, each side can retain no more than 700 deployed ICBMs, deployed
SLBMs, and deployed heavy bombers equipped to carry nuclear armaments. The treaty also
limits each side to no more than 1,550 deployed warheads; those are the actual number of
warheads on deployed ICBMs and SLBMs, and one warhead for each deployed heavy bomber.
