Government Document
The Department of Defense (DOD) has continuing efforts to modernize its airlift and tanker fleets by investing billions of dollars to modify legacy airlift systems, such as the C-5 and C-130, and procure new aircraft, such as a tanker replacement. Acquisition has been on GAO's list as a high risk area since 1990. GAO has reported that elements contributing to a sound business case for an acquisition are missing or incomplete as DOD and the services attempt to acquire new capabilities. Those elements include firm requirements, mature technologies, a knowledge-based acquisition strategy, a realistic cost estimate, and sufficient funding. Acquisition problems that include failure to limit cost growth, schedule delays, and quantity reductions persist, but fiscal realities will not allow budgets to accommodate these problems any longer. Today's testimony addresses (1) the analyses supporting the Department of Defense's (DOD) mobility capabilities and requirements and (2) actions that are needed to improve the outcomes of weapon system acquisitions. For this testimony, GAO drew from issued reports, containing statements of the scope and methodology used, as well as recently completed work not yet reported. GAO's work was performed in accordance with generally accepted government auditing standards. Past GAO reports, including two recently issued, raise concerns about the quality of analyses underpinning the programmatic decision-making surrounding DOD's airlift requirements. In September 2006, GAO issued our report (GAO-06-938) on DOD's Mobility Capabilities Study (MCS). The MCS determined that the projected mobility capabilities are adequate to achieve U.S. objectives with an acceptable level of risk during the period from fiscal years 2007 through 2013; that is, the current U.S. inventory of aircraft, ships, prepositioned assets, and other capabilities are sufficient, in conjunction with host nation support. GAO's report stated that conclusions of the MCS were based on incomplete data and inadequate modeling and metrics that did not fully measure stress on the transportation system. GAO further observed that the MCS results were incomplete, unclear, or contingent on further study, making it difficult to identify findings and evaluate evidence. It was not clear how the analyses done for the study support DOD's conclusions and GAO suggested that decision makers exercise caution in using the results of this study to make programmatic decisions. In March 2007, GAO reported (GAO-07-367R) on the lack of mandatory analyses to support a passenger and cargo capability for the new replacement refueling aircraft, the KC-X tanker. Contrary to mandatory Air Force implementing guidance, the Air Force proposed a capability without analyses identifying an associated gap, shortfall, or redundancy. GAO believes that without sound analyses, the Air Force may be at risk of spending several billion dollars unnecessarily for a capability that may not be...
