(See the below table) According to the data as of February 5, 2018—the deadline for reducing their strategic arsenals under the treaty—the number of Russian and U.S deployed strategic delivery vehicles and deployed/non-deployed strategic delivery vehicles/launchers, besides deployed strategic warheads, fell below the limit. The two countries declared they have met the limits for strategic nuclear forces.
