The State Department released New START aggregate data for Russia and the United States. As of 1 March 2013, Russia had 492 deployed strategic delivery systems, 1480 accountable operational warheads, and the total of 900 launchers. The U.S. March 2013 numbers are 792, 1654, and 1028 respectively.
In the previous data exchange, reflecting the status of the strategic forces as of 1 September 2012, Russia declared 491 deployed delivery systems, 1499 warheads, and 884 deployed and non-deployed launchers.
The 16 launchers that were added to the total could be the launch tubes of the Vladimir Monomakh submarine that was launched (entered water) in December 2012 - once it happened, the tubes are counted against the non-deployed launchers limit.
