The following tables are based on official data exchanged between the parties
to the START I treaty. A START I Memorandum of Understanding (MOU) is produced
at the beginning and middle of each year, and is declassified three months
after the initial data exchange. Under the terms of the START I treaty
the main unit of account is the launcher: the missile silo, mobile launcher,
or bomber. Even after a missile is removed from the silo, that silo still
counts as a launcher for the type of missile for which it was designed,
and is counted in the MOU data. For START I purposes both the missile and
the warheads it carried will continue to be counted until the silo is destroyed,
the destroyed silo has been inspected, and a 90 day period after inspection
has elapsed. For more information, please see the explanation
of START I counting rules.

NRDC RUSSIAN STRATEGIC STOCKPILE ESTIMATE END OF 1997
This estimate, by Robert Norris and William Arkin of the Natural Resources
Defense Council (NRDC), is based on START I data. The data have been corrected
by not counting missiles and bombers that have been withdrawn from service,
but which are still START accountable. Norris and Arkin also count ALCM-capable
bombers at their full loading, and thus the total number of air-delivered
warheads is higher than under the START I counting
rules. NRDC has also compiled a tables of US and Soviet/Russian force
levels since 1949, see the NRDC
Web site .
