The U.S. State Department released aggregate New START numbers from the 1 March 2016 data exchange. Russia declared 1735 deployed warheads, 521 deployed launchers, and 856 total launchers. In September 2015 the numbers were 1648, 526, and 877 respectively.
The increase of 87 deployed warheads is most likely due to the deployment of Bulava missiles on the Vladimir Monomakh submarine that was completed in April 2015. Some older missiles were apparently withdrawn from service.
The U.S. numbers in March 2016 were 1481 warheads, 741 deployed and 878 total launchers (1538, 762, and 898 in September 2015).
