Unmanned Aircraft Systems: New DOD Programs Can Learn from Past Efforts to Craft Better and Less Risky Acquisition Strategies

摘要

Through 2011, the Department of Defense (DOD) plans to spend $20 billion to significantly increase its inventory of unmanned aircraft systems, which are providing new intelligence, surveillance, reconnaissance, and strike capabilities to U.S. combat forces--including those in Iraq and Afghanistan. Despite their success on the battlefield, DOD's unmanned aircraft programs have experienced cost and schedule overruns and performance shortfalls. Given the sizable planned investment in these systems, GAO was asked to review DOD's three largest unmanned aircraft programs in terms of cost. Specifically, GAO assessed the Global Hawk and Predator programs' acquisition strategies and identified lessons from these two programs that can be applied to the Joint Unmanned Combat Air Systems (J-UCAS) program, the next generation of unmanned aircraft.
