Because of limitations in the Army’s process for determining war reserve spare parts requirements, uncertainties exist regarding the accuracy of the war reserve spare parts requirements and funding needs. These limitations include (1) not using the best available data on the rate at which spare parts would be consumed during wartime for its war reserve spare parts requirements calculations, (2) having a potential mismatch between the Army’s process for determining spare parts requirements for war reserves and how the Army plans to repair equipment on the battlefield, and (3) lacking a fact-based assessment of industrial base capacity to provide needed parts for the two major theaters of war scenario. Some uncertainties are likely to remain for the foreseeable future as the Army contemplates a significant transformation of its forces and other changes are considered affecting military strategy and force structure. However, improvements in the above areas could lessen the degree of uncertainties that exist.
What GAO Found

According to the current National Military Strategy the United States should be prepared to fight and win two nearly simultaneous wars in different parts of the world. Military policy calls for each of the services to acquire and maintain enough war material inventories to sustain a two-war scenario until the industrial base can resupply our armed forces. Because of limitations in the Army's process for determining war reserve spare parts requirements, however, the accuracy of the war reserve spare parts requirements and funding needs are uncertain. These limitations include (1) not using the best available data on the rate at which spare parts would be consumed during wartime for its war reserve spare parts requirements calculations, (2) having a potential mismatch between the Army's process for determining spare parts requirements for war reserves and how the Army plans to repair equipment on the battlefield, and (3) lacking a fact-based assessment of industrial base capacity to provide needed parts for the two-war scenario. Uncertainties are likely to persist for some time as the Army contemplates a significant transformation of its forces and other changes are considered affecting military strategy and force structure. However, improvements in the above areas could lessen the degree of uncertainties that exist.
