What combination of strategic mobility forces--airlift planes, sealift ships, and sets of military equipment prepositioned abroad--best suits the needs of the United States? Since the Department of Defense (DoD) no longer plans to confront a well-armed Soviet Union in a European conflict, some people might argue that its need for mobility forces has declined. But today the Administration envisions a smaller, yet more flexible, set of forces that can counter regional aggressors anywhere in the world. For that reason, proponents say a robust system for transporting military forces over intercontinental distances is more important than ever.
This analysis, conducted by the Congressional Budget Office (CBO) for the House Committee on National Security, looks at several alternatives for modernizing DoD's strategic mobility forces and compares the costs and capabilities of each option with those of the Administration's plan. In keeping with CBO's mandate to provide objective analysis, the study makes no recommendations.
Rachel Schmidt of CBO's National Security Division prepared the study under the general supervision of Cindy Williams and R. William Thomas. Shaun Black developed CBO's analytic model for sealift analysis and wrote sections of Chapter 3. Nathan Stacy wrote most of the discussion of the Civil Reserve Air Fleet in Chapter 2 and Appendix B. Jo Ann Vines, Jeannette Deshong, and Victoria Fraider of CBO's Budget Analysis Division provided the cost analysis. The author would like to thank Evan Christman, Ivan Eland, Wayne Glass, Frances Lussier, and Doug Taylor of CBO, as well as numerous employees of the Department of Defense and the military services, for their help. Philip Webre and Arlene Holen of CBO, David Kassing of RAND, and Owen Cote of Harvard University's Center for Science and International Affairs provided thoughtful comments on an earlier draft of the study. (The assistance of external participants implies no responsibility for the final product, which rests solely with CBO.)
Christian Spoor edited the manuscript, and Marlies Dunson provided editorial assistance. Judith Cromwell produced drafts of the study. Kathryn Quattrone and Jill Sands prepared the report for publication.
