The conclusions of the bottom-up review influenced the development of the FY 1994 Defense budget, although detailed work on the budget had begun as soon as Aspin took office. In March 1993 Aspin introduced a FY 1994 budget proposal costing $263.4 billion, about $12 billion below current levels, and reflecting cuts in the military services similar to those later included in the bottom-up review. To some critics of high military spending, Aspin's budget plan differed little from that of the Bush administration.
