CBO Paper: Long-Term Implications of Current Defense Plans: Summary Update for Fiscal Year 2005 [open pdf - 2MB]
From the Summary and Introduction: "Decisions about national defense that are made today - whether they involve weapon systems, military compensation, or numbers of personnel - can have long-lasting effects on the composition of the U.S. armed forces and on the budgetary resources needed to support them. In the past two years, the Congressional Budget Office (CBO) has published a series of reports projecting the resources that might be needed each year over the long term to carry out the plans contained in the Administration's fiscal year 2003 and then 2004 Future Years Defense Program (FYDP). The Department of Defense (DoD) has since prepared a new FYDP reflecting changes that have been made to the department's programs and priorities over the past year. This paper updates CBO's projections to be consistent with the plans contained in the 2005 FYDP, which covers fiscal years 2005 through 2009. The total resources that the new FYDP anticipates for defense over the 2005-2009 period do not differ substantially from those in the 2004 FYDP."
