AIR DEFENSE Taiwan faces one of the most difficult air defense problems in the world. Because of that, it cannot easily look to how other nations have invested in air defenses to guide its force structure decisions. What makes Taiwan’s air AIR DEFENSE defense problem so difficult is the combination of its proximity to China and the massive investments that the People’s Republic of China has made in a range of systems that threaten Taiwan’s aircraft. China now has the capability OPTIONS FOR to destroy all of Taiwan’s aircraft at their bases. Although some aircraft might be safe in caves, Taiwan cannot use them from those shelters for sustained OPTIONS FOR combat operations. Thus, Taiwan needs to rethink how it can accomplish its air defense goals in a major conflict without heavy reliance on its fighter aircraft. Fighter aircraft are not the only element of Taiwan’s air defense; surface-to-air missiles are the other major element. Still, air defense in a major war is only one possible category of demands for Taiwan’s air defenses. A variety of TAIWAN more-limited military conflicts could draw on air defense capabilities. This report analyzes Taiwan’s options for allocating future resources for air defense capabilities. It describes the essential air defense problem posed by TAIWANAn Assessment of Relative Costs and Operational Benefits the People’s Liberation Army, characterize the current capabilities and level of funding that Taiwan invests in air defense, and then develop several alternative investment strategies. The authors then test those investment strategies in three vignettes that span the range of conflict, from quite limited coercive uses of force to a full invasion.

It begins with a description of the PLA air- power threat and how it could overwhelm Taiwan’s current defen- sive capabilities, describes a set of force structure options in a cost- constrained environment, and compares those options using several vignettes that highlight key operational differences. The analysis pro- vides a basis to inform decisions about a direction for Taiwan’s defense program to meet current air defense challenges. These involve not only new systems but also new concepts for employment. This should be of interest to those in Taiwan concerned about defense issues and to those in the United States and other countries who care about Taiwan’s secu- rity and the overall security of northeast Asia.
