Note: The loadings given above for the U.S. nuclear submarine force represent maximum potential loadings with the available inventory of warheads and launchers (this is true of the bomber and ICBM forces as well). In January 1998 STRATCOM (U.S. Strategic Command) indicated that the warhead loadings currently being used for submarines on patrol are much lower than this. It has not been disclosed why this is.
